Around 2005 it was time to start the number name game. 3B, 3C, etc.
In late 2004 Intel and AMD both were having huge battles in processors to see who could reach the top speed. AMD stopped labeling their CPU speeds and instead started using rating numbers as names. So instead of what we normally expected with an AMD Athlon 2.8Ghz to compete with an Intel Pentium 4 2.8Ghz, we now had an Athlon XP 2800+ supposed to be rated at 2800, but ran at around 2.1Ghz.
Intel was reaching the four gigahertz speed barrier. Without overclocking it seemed that neither company could reach or break the magical 4Ghz range. At the end of 2004 Intel released a Pentium 4 Extreme Edition that reached 3.73Ghz. A true 4Ghz chip is listed on http://ark.intel.com, and a few engineering samples saw the light, but were canceled for the Dual Core chips. AMD started banking on 64-bit and so the Althon 64 brand started to come about, but still kept the rating name instead of actual speed name.
The name game starts at Intel in early 2005 with the Dual Cores, Single Cores, and even the Celeron processors. It became really fun trying to recommend technology to people based on the number name game.
By mid to late 2005 all the big OEM computer makers were selling single core, dual core, and cheap single core systems with "code name" processors. On the AMD side we had Athlon XP, 64, and Sempron systems. The Intel side had Pentium 500, 800, and 900 series, and Celeron 300 series names.
At least when AMD launched the dual cores, they made it easy to recognize by adding the X2 nomenclature to the name. You had to decipher the code on the Intel chips.
I previously posted information about hardware system 3a which is a Celeron D 351, 3.2Ghz processor.
The Intel 945G platform I am using has a huge range of supported processors. The board will run clear back to the first Pentium 4 socket 775 model all the way up to many of the Core 2 Duo models.
The board dropped all the way down to a 533Mhz bus to run the Celeron D CPU, and scales up to a 1066Mhz for the Core 2 Duo.
I will include revision letters to the additional processors tested on the same components in system 3. Only the CPU will change.
System, CPU, Speed, Cores/Threads, Cache, Bus, Codename, Lithography, Stepping, Revision, Features
3 -- Intel Pentium D 820, 2.8Ghz Dual Core, 2 Cores / 2 Threads, 2MB, 800Mhz, Smithfield, 90nm, Stepping 4, Revision-A0, 14x Multiplier, 200 FSB, MMX, SSE (1,2,3), EM64T
3a -- Intel Celeron D 351, 3.2Ghz, 1 Core / 1 Thread, 256KB, 533Mhz, Prescott, 90nm, Stepping 9, Revision G1, 24x Multiplier, 133 FSB, MMX, SSE (1,2,3), EM64T
3b -- Intel Pentium 521, 2.8Ghz HyperThreading, 1Core / 2 Threads, 1MB, 800Mhz, Prescott, 90nm, Stepping 9, Revision G1, 14x Multiplier, 200 FSB, MMX, SSE (1,2,3), EM64T
3c -- Intel Pentium D 940, 3.2Ghz Dual Core, 2 Cores / 2 Threads, 4MB, 800Mhz, Presler, 65nm, Stepping 4, Revision C1, 16x Multiplier, 200 FSB, MMX, SSE (1,2,3), EM64T, VT-X
As you can see, the Smithfield Pentium D 820 is basically two Pentium 4 521 Prescott cores on one die. The Celeron D 351 is a Pentium 4 521 with no hyperthreading, part of its cached removed, and a speed bump.
The Pentium D 900 Presler series was part of the die shrink to 65nm and gained more cache memory.
When AMD successfully launched their 64-bit chips Intel claimed few home consumers would be interested in 64-bit computing. Intel never claimed they were wrong, but answered by adding EM64T or their version of 64-bit instructions to the processor.
As virtualization started to become popular not only in servers but on the desktop as well Intel added VT-X to the Presler processors to benefit virtualization on the hardware.
