CPU News


Sep 1
	Last week's updates: I added CPU pages for all recently released Core 2 Duo Mobile and Core 2 Quad Mobile processors. Core 2, K10, K8 and K7 family pages now include relationship tables - these show which family relate to current CPU family. See how it looks on the Athlon 64 page. Some CPU pages now use tabbed navigation. Some CPU pages now include breadcrumb navigation - links at the top of the page that allow visitors to quickly return to parent, or parent's parent, etc pages. Posted more new pictures of Celeron M and Pentium M processors.		Intel Pentium M 745

Aug 24
	This was a short week for me due to vacation, so not much work was done on the site. I posted S-spec numbers of all recently released Core 2 mobile, Xeon and Celeron M processors, and updated identification and processor number pages. CPU pages for new processors will be added next week.

Aug 16
	I split Core microprocessors family into Core Solo and Core Duo families. This was done to eliminate possible confusion of the Core family with Core microarchitecture. A few new pictures of Core Solo/Duo CPUs were added to both families. You can find the links to pages with new pictures below. I also added Core 2 Duo and Core 2 Quad processors released this week. I'm leaving for vacation for 5 days. All submitted comments will be approved and e-mails answered when I get back.

Aug 10
	This week updates: All new Core 2 Duo mobile processors were added to the site. This includes not just CPU pages, but also processor numbers, CPU charts and identifications pages. Many new S-Spec numbers, primarily for Xeon, Celeron M and Core 2 Duo families, were added to the S-Spec database. I posted pictures of Celeron M, Pentium M and Pentium Dual-core mobile processors.

Aug 3
	I did many small site updates this week - each one of them wasn't big enough to post it in the news, so today I decided to post the summary of what I did: New AMD processors released in the last two months were added to Phenom X4 family (thanks to those people who constantly reminded me about them :), Turion X2 Ultra family, and a few other K8 families. I created its own page for Athlon 64 X2 for Notebooks family. All new processors were included into combined CPU chart, and I also updated model numbers and identification pages. Other changes were really minor - a few new AMD stepping codes and Intel S-Spec numbers, and page corrections. I believe that modern AMD families are now up to date. I will try to add all recently released Intel processors next week - again, this will involve a lot of small changes here and there, so I won't post news during the week, and will only post a summary of changes next Sunday.

Jul 26
	I added identification / site search input box to all S-Spec and to some CPU pages. In addition to that all these pages now include better related CPUs/S-Spec numbers search tool - the pages still support old options (finding lower, the same and higher frequency processors, or finding CPUs with the same CPUID or stepping), and you can also specify whether you want the same FSB and socket type. In unrelated news, I'm leaving for a few days for vacation. All submitted comments will be approved when I get back.

Jul 22
	Recently updated page with Intel processor numbers was split into two pages: desktop processor numbers and mobile processor numbers.

Jul 19
	I posted a few pictures of socket 478 and socket 775 Celeron_D processors.		Intel Celeron D 355
		Intel Celeron D 335 - RK80546RE072256 / NE80546RE072256 (BX80546RE2800C) Intel Celeron D 340 - RK80546RE077256 / NE80546RE077256 (BX80546RE2933C) Intel Celeron D 346 - JM80547RE083CN / HH80547RE083CN (BX80547RE3066CN) Intel Celeron D 352 - HH80552RE088512 (BX80552352) Intel Celeron D 355 - HH80547RE093CN (BX80547RE3330CN) Intel Celeron D 356 - HH80552RE093512 (BX80552356)

Jul 18
	AMD model numbers and Intel processor numbers pages are now up to date. Intel processors numbers page is getting really big - in the near future I'm going to split it into two pages, possibly into desktop processor numbers and mobile processor numbers.

Jul 16
	I uploaded benchmarks of a few socket 775 Pentium 4 and Pentium D microprocessors to the CPU benchmark database. CPU pages were updated too.

Jul 13
	All benchmark data that was recently added to the benchmark database, is now added to CPU pages too. The pages now include easy way to compare the CPU with other CPUs/families. For example, please see it looks on a socket 939 Athlon 64 X2 4800+ page.

Jul 12
	I uploaded pictures of Celeron Northwood CPUs. With the exception of Celeron 1.6 GHz, all these are very common microprocessors. The Celeron 1.6 GHz SL7EZ is the slowest Pentium 4-based Celeron built on 0.13 micron process. It seems that not many of SL7EZ processors were manufactured, so they are not easy to find.

Jun 28
	I added a few benchmarks of Celeron M, Core Solo and Core Duo processors to the benchmark database.

Jun 24
	I added a few pictures of Motorola 68030 microprocessors, including two microprocessors with "PC" prefix (supposedly engineering / pre-production samples), and one mechanical sample:		Motorola PC68030FE25B
		Motorola XC68030MECHFE Motorola PC68030FE20 / PC68030FE20B Motorola PC68030FE25 / PC68030FE25B Motorola XC68030RC40 / XC68030RC40B

Jun 22
	Benchmarks of Pentium M processors were added to the benchmark database.

Jun 21
	I added pinouts of Pentium 4 and Pentium M microprocessors.

Jun 15
	Browse/Search feature of our Benchmark database was greatly improved: It is now possible to select individual processors in addition to CPU families. The resulting chart can optionally show processor performance as percentage relative to selected CPU. For every test result we now display links to page with detailed information on the test system and the CPU. Individual CPUs can now be removed from the chart.

Jun 14
	I uploaded test results of about 10 socket AM2 microprocessors to the benchmark database. I have many socket 939 CPUs in collection, but I can't test them due to problems with my socket 939 motherboard, so there won't any socket 939 benchmarks soon. Next week I will post more benchmarks of socket 754 processors, and then I will start testing Intel processors.

Jun 13
	I added pictures of Athlon 64 X2 microprocessors:		AMD Athlon 64 X2 4600+
		AMD Athlon 64 X2 3800+ - ADA3800DAA5CD (ADA3800CDBOX) AMD Athlon 64 X2 3800+ - ADA3800IAA5CU (ADA3800CUBOX) AMD Athlon 64 X2 3800+ - ADD3800IAA5CU AMD Athlon 64 X2 4000+ - ADO4000IAA5DD (ADO4000DDBOX) AMD Athlon 64 X2 4200+ - ADA4200DAA5BV (ADA4200BVBOX) AMD Athlon 64 X2 4600+ - ADA4600DAA5BV (ADA4600BVBOX) AMD Athlon 64 X2 4800+ - ADA4800DAA6CD (ADA4800CDBOX)

Jun 8
	More than 50 new S-spec numbers were added to the S-Spec database.

Jun 7
	More benchmark results for socket 754 processors were added to the benchmark database. Six of the 9 tested processors are mobile Turion 64 and Mobile Sempron CPUs. Next week I'm going to post test results of remaining socket 754 CPUs (that I have), and I will also post benchmarks of Athlon and Athlon 64 X2 socket AM2 processors.

Jun 5
	Links to four CPU and chip collector sites were added to Links section: 155la3.ru Collection of electronic rarities (in Russian), CPU-Ukraine, Silirium.ru Online Chips Museum, and Vintchip Chip collection.

May 31
	I added pictures of 9 different K8 Sempron microprocessors, including 4 boxed Sempron CPUs. I took a few pictures of each boxed Sempron. To see them please go to individual Sempron pages and then click on the "More pictures" link.		AMD Sempron 64 LE-1150

May 26
	Socket 940 page was added to the Sockets section.

May 24
	Part numbers of RoHS-compliant i960 microprocessors were added to Intel 80960 family. Also, the family now includes information on 80960RS and 80960VH CPUs.

May 21
	Benchmark results of socket 754 K8 Sempron and Athlon 64 processors were uploaded to the benchmark database. I have a small pile of single-core socket 939 / AM2 processors ready to be tested, so more benchmark results will be coming in the next two weeks. For now I will include only dhrystone, whetstone, superPI, 3DMark and Sandra tests.

May 20
	I uploaded a few pictures of AMD Athlon 64 processors. This update includes one interesting pre-release processor with non-standard part number ADAAA2800ACN5, and four socket 939 CPUs:		AMD Athlon 64 3700+
		AMD Athlon 64 2800+ - ADAAA2800ACN5 AMD Athlon 64 3200+ - ADA3200DAA4BW (ADA3200BWBOX) AMD Athlon 64 3500+ - ADA3500DAA4BP (ADA3500BPBOX) AMD Athlon 64 3500+ - ADA3500DAA4BW (ADA3500BWBOX) AMD Athlon 64 3700+ - ADA3700DKA5CF (ADA3700CFBOX)

May 19
	I added missing B1- and B2-stepping Third Generation Opterons and updated Opteron model numbers page. I also added a page with identification of Phenom and Third Generation Opteron processors. Identification tool was updated too - it can now recognize all (or so I hope) processors from K10 family.

May 17
	Search benchmarks page was re-written. Currently it can display benchmark results for one or more CPU families as a simple bar chart. I also updated benchmarks administration page. It is no longer possible to add benchmarks of new types (besides those that are already in the database). This is a temporary restriction, I will remove it when I add come up with a way to add new benchmark types.

May 12
	National Semiconductor Geode SC2200 family was added to the site. I apologize for the lack of updates in the past few weeks - I spent way more time implementing benchmark database than I planned for it, and since last week I'm working on important side project. I hope to finish the project by next weekend, then I'll have more spare time to work on new site updates.		National Semiconductor Geode SC2200UFH-266

May 3
	CPU benchmark database now includes results of all benchmarks of Pentium, K5, 6x86, Pentium II, and other processors, which I did long time ago, and which you can find on old benchmarks page. The new page is difficult to use, but it should be significantly improved in the near future.

Apr 28
	On December 31st of last year I mentioned in the news that I'm working on a new CPU benchmark database. I was planning to finish it in the January of this year, but due to lack of time - I spent lot of time working on other areas of the site - the project was delayed. Today I finished the first phase of this project and put the database online. The database is not limited to specific benchmarks, so you can post anything that may serve as a benchmark. For example, a loop from 1 to 1000 or 10000 written in BASIC language on a very old computer can be considered a benchmark. Another important feature of the database - it is not limited to AMD and Intel processors, or x86 CPUs, and Windows OS. So, you can run any type of benchmark on any OS on any system, and add results to our database. The database search page doesn't have many options yet - it will be improved in the near future. A few notes about posting your own benchmarks. To post the benchmarks you will need to register in the forum (the administration page and the forum share usernames and passwords), and proceed to the administration page. You don't need to register if you're already a registered user in the forum. Please, don't post bogus benchmarks - I will take them down.

Apr 27
	Recently released Phenom 8x50 triple-core processors and energy efficient Athlon X2 4x50 CPUs were added to the site. I also added Sempron X2 CPUs - these processors were not officially launched by AMD, although they're already selling in online stores here in US.

Apr 16
	AMD K7 and K8 stepping codes pages were updated today. I also started new pages - AMD K10 stepping codes and Timeline of AMD K10 stepping codes. I don't have many stepping codes for Phenom and Third Generation Opteron processors yet, so if you have any new ones or even existing ones with different date codes please submit them. When you submit them please specify complete second line from the CPU markings, i.e. the stepping code, date code and other rest of the line. This is how submitted stepping code should look like: CAAZB AA 0743FPMW.

Apr 15
	I added missing processor modules to Mobile Celeron modules page. The page included only older modules based on 0.25 micron mobile processors. All CPU modules added today are based on 0.18 micron Coppermine core, and have PMN* part numbers.

Apr 13
	Earlier this week AMD released new Third-Generation Opteron processors based on B3 core stepping. All these processors were added to the site.

Apr 10
	I didn't have any pictures of socket 775 processors on the site, so I added a few of them today:		Intel Pentium D 915
		Intel Pentium D 915 Intel Core 2 Duo E6300 Intel Pentium 4 510/510J 2.8 GHz Intel Pentium 4 524 3.06 GHz Intel Pentium 4 630 3.0 GHz

Apr 7
	Banias core and Dothan core pages were added today.

Apr 6
	New pictures of VIA C3 / VIA Cyrix III processors were added today. I've made a few changes to the VIA C3 family and put some basic description of it, but not everything was finished. I will write better description, add information on Nehemiah processors, and create VIA CPU charts in the next week or two.		VIA Cyrix III-466MHz
		VIA C3-466MHz / Cyrix III-466MHz VIA C3-550MHz / Cyrix III-550MHz 1GigaPro C3-667AMHz EBGA (ES) VIA C3-800AMHz EBGA (1.65V) VIA C3-933AMHz EBGA (1.35V and 1.4V) VIA C3-1.0AGHz EBGA

Apr 2
	More than 50 new S-spec numbers were added to the S-Spec database. You can find the list of all added numbers on this page. As you can see there, two thirds of newly added S-Spec numbers are engineering samples, and about half of all added S-Specs are for Core 2 Duo Mobile family.

Apr 1
	All Pentium 4 core pages were updated, and I added Pentium D/Pentium Extreme Edition Smithfield and Presler core names.

Mar 31
	Socket AM2 page was added to the Sockets section of the site.

Mar 30
	sSpec Chart tool now can filter S-Spec numbers by processor core name, the number of cores, and microprocessor features such as EM64T, Virtualization, etc.

Mar 29
	National Semiconductor Geode SC1200 family was added to the site:		National Semiconductor Geode SC1200UFH-266

Mar 27
	7 new AMD Phenom processors, that were released today, were added to AMD Phenom X3 and Phenom X4 pages. I also created CPU charts for all of them and added the CPUs to combined CPU chart.

Mar 26
	I posted data on Luke-Lite CoreFusion microprocessor family. Luke-Lite family in some way is similar to Luke CoreFusion family, except that it includes less feature-rich chipset. The CPU core in Luke and Luke-Lite microprocessors is the same.

Mar 25
	I added a small glossary of CPU-related terms. All pages included in the glossary were originally created as help pages for CPU and sSpec sections of the CPU-World site. The glossary has many terms missing, I will be slowly adding those over the course of the next few months.

Mar 24
	I added a page with information on Socket 754.

Mar 23
	I added a few pictures of K8 Sempron microprocessors and updated pages for many Sempron 64, Athlon 64 and other K8-based processors. all updated pages now include help information on HyperTransport technology, AMD64 technology and Enhanced Virus Protection.		AMD Sempron 64 3000+
		AMD Sempron 64 2600+ - SDA2600AIO2BA (SDA2600BABOX / SDA2600CVBOX) AMD Sempron 64 2600+ - SDA2600AIO2BX (SDA2600BXBOX) AMD Sempron 64 2800+ - SDA2800AIO3BA (SDA2800BABOX / SDA2800CVBOX) AMD Sempron 64 3000+ - SDA3000DIO2BI

Mar 21
	I added three new Xeon cores - Drake, Tanner and Cascades, and updated design of all Pentium II/Pentium III core pages. In my opinion, the updated page design slightly improves navigation and provides more details on previous, next and related core generations.

Mar 17
	I added information on and pictures of VIA Mark CoreFusion CPUs:		VIA Mark CoreFusion 800MHz
		VIA Mark CoreFusion 533MHz VIA Mark CoreFusion 800MHz

Mar 16
	Information about AMD Geode LX processors was added to the site. Geode LX microprocessors are based on Geode GX2 and include many enhancements: larger level 1 cache, level 2 cache, faster memory controller and GeodeLink interface units, better graphics controller, security block and video input port. Unfortunately, I don't have any pictures of Geode LX CPUs processors because I don't have the processors in my collection.

Mar 12
	VIA Luke CoreFusion family was added to the site.		VIA Luke CoreFusion 1.0GHz
		VIA Luke CoreFusion 533MHz VIA Luke CoreFusion 1.0GHz

Mar 8
	National Semiconductor Geode GX2 CPU family was added to the site:		AMD Geode GX 500
		AMD Geode GX 466 AGXD466EEXD0BD AMD Geode GX 500 AGXD500EEXE0BC AMD Geode GX 533 AGXD533EEXF0BD

Mar 5
	S-Spec database now includes S-Spec numbers of Intel 80860 and 80960 microprocessors. These were added primarily for CPU collectors - I doubt anybody else would be interested in them...

Mar 2
	New processors and historical price charts were added to Turion 64 X2 family page. Historical charts were also added to Turion 64 page, and I posted data on Celeron 215 and 220 CPUs.

Feb 29
	I added a few pictures of mobile Pentium processors. Some pictures are not displayed on the CPU pages, to get to these pictures you will need to click on the "More pictures" link of the CPU pages.		Intel Mobile Pentium MMX 233
		Intel Mobile Pentium 100 - TT80502100 (PP100) (one marked PP100 and another marked TT80502100) Intel Mobile Pentium 133 - TT80502133 (PP133) Intel Mobile Pentium MMX 166 - TT80503166 (TT166) Intel Mobile Pentium MMX 233 - TT80503233 (TT233)

Feb 24
	Signetics 2650 architecture page was added to the site.

Feb 22
	Historical price charts for AMD Phenom, AMD Athlon 64 FX and all AMD Opteron processors were added to the K8 and K10 families - you can find the charts in "Related links" menu on CPU pages. Remaining price charts for AMD processor will be added by the end of next week. On related note, if anybody has official price lists, not necessary the latest ones, for Intel processors please contact me or send them to me directly (you can find my e-mail at contact us page).

Feb 21
	I added 9 pictures of Z80 microprocessors, including two CPUs made by ROHM and Kawasaki - these manufacturers are new for the Z80 CPU family page:		Mostek MKB3880P-84
		DDR U880D (FWE) Kawasaki KL5C8400C Mostek MKB3880P-84 NEC D70008A ROHM BU18400A-PS SGS-Thomson Z8400BB1 Toshiba TMPZ84C00P Toshiba TMPZ84C00AM-6 Toshiba TMPZ84C00AM-8

Feb 9
	I added a few pictures of Athlon XP-M processors:		AMD Mobile Athlon XP-M 1600+
		AMD Mobile Athlon XP-M 1600+ - AXMS1600FWS3B AMD Mobile Athlon XP-M 1600+ - AXMS1600GXS3C AMD Mobile Athlon XP-M 2000+ - AXMS2000GXS4C AMD Mobile Athlon XP-M 2200+ - AXMT2200GWS4C AMD Mobile Athlon XP-M 2400+ - AXMH2400FQQ4C

Feb 8
	Xeon 3100 and 3300 series microprocessors were added today. I believe those were the last processors missing from Xeon family. Both 3100 and 3300 series microprocessors are produced on 0.045 micron technology, packaged in 775-pin package, and can work only in single-processor systems. Xeon 3100 are dual-core processors and Xeon 3300 are quad-core processors. Both families are essentially re-branded Core 2 Duo and Core 2 Quad CPUs. Today I also added Celeron Dual Core CPU family. At this time this family includes only one CPU - Celeron E1200. Released just two weeks ago, these Celerons are not much different from Pentium Dual-Core family. Beside new brand name and smaller L2 cache there are no other important differences between Pentium and Celeron Dual-Core CPUs.

Feb 2
	Information about all recently posted Xeon processors was added to combined CPU chart. I also created separate charts for Xeon DP, Xeon MP, Xeon 3000, Xeon 5000 and Xeon 7000 CPUs. You can find links to these charts at the bottom of Microprocessor charts page.

Feb 1
	I added Core 2 Duo, Core Quad and Core 2 Duo mobile processors that were released in January. I also updated CPU charts and Intel processor numbers page with this data. Core 2 family page should be now up to date.

Jan 26
	I posted information on processors from Xeon 5300 and Xeon 5400 series: Xeon 5300 - quad-core processors for single- and dual-processor systems. These processor were built on 0.065 micron technology, and they feature large 8 MB level 2 cache. Xeon 5400 - released less than three months ago, these quad-core microprocessors are built on the latest Intel 45nm high-k metal gate silicon technology. Xeon 5400 processors feature larger L2 cache (12 MB) and SSE4.1 instruction set.

Jan 25
	Today I added a few more Xeon families to Intel Xeon family page: Xeon 5100 - first Xeon microprocessors based on Core micro-architecture. Many features of these processors can now be found in almost any Core 2 desktop CPU - shared L2 cache, Intel 64 technology (formerly EM64T), Virtualization technology and Execute disable bit. These processors could work only in single and dual-processor systems. Xeon 5200 - built on 0.045 micron technology, these CPUs have moderate power consumption while running at very high frequencies - up to 3.4 GHz. The size of level 2 cache on these processors was increased to 6 MB. Xeon 7300 - quad-core Xeon processors based on 0.065 micron technology. The 7300 have two die in the package - each die has two microprocessor cores. Like all Xeons from 7000 series, these processors are not limited to dual-processing, and can work in 4 or more processor systems. Xeon 7200 - dual-core 0.065 micron Xeons. These are similar to 7300 CPUs, they even have two die in the processor package, except that each die has only one CPU core. This is very different from all other dual-core Core 2 processors - those usually have one die with two microprocessor cores.

Jan 19
	Today and earlier this week I added many new S-Spec numbers, including specification numbers of Core 2 processors that were released earlier this month, small number of S-Spec numbers of engineering samples, and majority of submitted S-Spec numbers.

Jan 15
	I uploaded a few pictures of Xeon CPUs. Most of them are engineering or qualifications samples, including two processors, Xeon 1.3 GHz and Xeon MP 2.8 GHz with 4 MB L3 cache, that never went into production:		Intel Xeon MP 2.8 GHz
		Intel Xeon 1.3 GHz - 80528KC013G0K [ES] Intel Xeon MP 1.4 GHz - YF80528KC017512 (BX80528KL140GD) Intel Low voltage Xeon 2.4 GHz - RK80532EE056512 [ES] Intel Xeon 2 GHz - RN80532KC041512 (BX80532KC2000D / BX80532KC2000DU) [ES] Intel Xeon MP 2 GHz - RN80532KC0411M (BX80532KC2000E) [ES] Intel Xeon MP 2.8 GHz - RN80532KC0724M [ES] Intel Xeon MP 7030 - NE80560KG0722MH (BX80560KG2800F) [ES]

	Today I added the following Xeon microprocessors based on Core micro-architecture: Low voltage and ultra-low voltage Xeon processors with Sossaman core. These are essentially Core Duo microprocessors that can work in dual-processor systems. Like Core Duo CPUs, these processors are packaged in 478-pin micro FC-PGA package, but the pinout of this package is different from Core Duo/Core Solo CPUs. Dual-core Xeon 3000 series processors. These CPUs are similar to desktop microprocessors with Conroe core, and they only work in uniprocessor systems. Xeons 3000 are manufactured in 775-pin Flip-Chip LGA package and work in socket 775 motherboards. Quad-core Xeon 3200 series processors. These CPUs are similar to Quad-Core desktop processor with Kentsfield core. They also work in socket 775 motherboards.

	New design of S-Spec pages is now online. Look and feel of the pages now closely matches look and feel of CPU information pages, that is the pages show the most important parameters in bold, include links to glossary, and provide a way to search for related S-Spec numbers. Search/Filtering form on the main and all family s-spec pages is now linked to the S-Spec chart.

	For very long time our S-spec pages had very basic search and filtering capabilities - it was only possible to filter by CPU frequency, bus speed, L2 cache size and package. Today I added S-Spec Chart which provides much better data filtering, displays more data and includes data sorting. The S-Spec chart works very similar to CPU chart, i.e. you can select which columns you want to display and can choose up to three different conditions per column. I had a preliminary version of this tool running on my development computer for last two months, and even that preliminary version proved very useful to me. I was able to find and fix some errors in S-Spec database, also the tool reduced research time for new Intel CPU families that I posted on the site. Hopefully this tool will be useful for everybody else.

	More information on Intel Xeon CPUs was added today. Now the Xeon page includes all NetBurst-based Xeon DP and Xeon MP microprocessors.

Jan 3
	I posted pictures of a few Celeron D microprocessors:		Intel Celeron D 320
		Intel Celeron D 320 - RK80546RE056256 / NE80546RE056256 (BX80546RE2400C) Intel Celeron D 325 - RK80546RE061256 / NE80546RE061256 (BX80546RE2533C) Intel Celeron D 330 - RK80546RE067256 / NE80546RE067256 (BX80546RE2667C)

	I updated Intel Xeon page with information on 0.13 micron and 0.09 micron Xeon processors. This update covers the following cores: Prestonia - 0.13 micron NetBurst-based processors with 400 MHz and 533 Mhz Front-side Bus. These CPUs have 512 KB level 2 cache, support SSE/SSE2 instructions and incorporate HyperThreading technology. Gallatin - this core is similar to Prestonia core, except that the Gallatin core adds 1 or 2 MB level 3 cache. Nocona - this 0.09 micron core features 64-bit technology, SSE3 instruction set, 800 MHz FSB and twice larger level 2 cache. Nocona CPUs don't have level 3 cache. Irwindale - enhanced version of Nocona core with 2 MB level 2 cache. This core also includes execute disable bit feature.
