CPU Instruction sets

The CPU's instruction set is the codes or instructions that the CPU can use to process its data. The more it has the more likely it is to be efficient. However all CPU's don't use the same instructions to process that data. Intel and AMD went there separate ways when adding more instructions to the basic instruction set. First to come out was MMX from Intel. MMX was Multimedia extensions, and it added extra instructions to the original set which was recognised by the original IBM 8086 CPU's.

Below is a table of what instruction sets each of the latest CPU's use. As well as some of there features and clock frequency range.

CPU Instruction Set(s) Chip Frequencies Other Info
AMD Athlon (original) MMX, 3DNOW 500Mhz - 1Ghz Used a cartridge instead of a chip. Had DDR functionality between CPU and cache.
AMD Athlon Thunderbird MMX, Enhanced 3DNOW 650Mhz - 1.4Ghz AMD went back to the socket after finding ways to increase the speed to these chips. Also uses DDR. Cache ran at full speed unlike the original Athlon.
AMD Athlon XP MMX,  3DNOW Professional* 1500+ (1.3Ghz) - 2800+ (1.73Ghz) A new core produced more power whilst making less heat. AMD also started to go off the MHz rating in favour of model numbers, in other words they used an old style PR rating based on the thunderbird.
AMD Athlon64 SSE2
3DNOW! Professional		 3200+ (more to be introduced) The Athlon 64 is the first CPU by AMD to use 64-bit operations. This chip is specifically design to use 64-bit Operating systems and Applications. It also uses a hyper transport link to get access to the memory instead of the normal FSB because of its inboard memory controller allowing it to bypass the chipset on route to the main memory.
Intel P4 MMX, SSE 2 Socket 423 1.3Ghz- 2Ghz
Socket 478 2Ghz - 2.4Ghz (now higher)		 The first CPU to use a 400Mhz system bus for its chip. changed to socket 478 to allow extra grounding pins, allowing it to go beyond 2Ghz.
Intel P4 Northwood MMX, SSE 2 2Ghz - 3.2Ghz The Northwood drops the micron size down to .13 and also adds an extra 256K of L2 cache to the previous version of the P4. Also as the chips got faster they got a FSB boost from 400Mhz (100*4) to 533Mhz (133*4)
Intel P4 Prescott PNI (Prescott New Instructions) Could be called SSE 3 3.2Ghz + Once again the New Pentium 4 is produced using an even smaller Micron technology. .09 in this instance. And like the Northwood the Prescott adds more cache. An extra 8K of L1 Data cache and an extra 512K of Level 2 Cache taking it a massive 1Mb of On Chip cache. SSE 3 offers an extra 13 instructions from SSE 2 you can find out about them at Geek.com
Intel PIII MMX, SSE 450Mhz - 1.4Ghz Went from the slot 1 form factor back to the sockets just like AMD did. This was Intel longest running CPU in terms of broadness of MHz in its chips.
Intel Celeron MMX, SSE Celeron PII 266Mhz - 533Mhz
Celeron PIII 533Mhz - 1.2Ghz		 The Celeron has gone through many stages from the PII to to the latest P4. The Celeron was always based on the power CPU with the cache cut down and the system bus knocked down as well (except in the case of the P4 Celeron where the system bus was kept at 400Mhz). This was either due to a fault meaning it could not be sold as the higher CPU or by design.
Intel Celeron Pentium 4 MMX, SSE 2 1.7Ghz-1.8Ghz
Celeron Tualatin MMX SSE 1Ghz - 1.2Ghz
Cyrix III MMX, 3DNOW 500Mhz - 700Mhz VIA was quick to drop to the .15 micron process. Unfortunately as with all the VIA CPU's the FPU prevented it from being anything more than a cheap reliable business type machine.
AMD Duron MMX, 3DNOW

SSE in the Morgan core

 Duron Spitfire 600Mhz - 950Mhz
Duron Morgan 1Ghz - 1.5Ghz		 The Duron has to be one of the best chips available for all concerned. It was an Athlon with 64K cache. The Morgan core even had the SSE built in like the Athlon XP. The price for these chips is very reasonable and is a fast CPU considering its aimed at the budget market.

* 3DNow Professional was labelled as such by AMD, the actual technology is that identical to SSE and is recognised as such by programs that support it.

The difference's between the CPU's are getting smaller as each company see's the advantages of their rivals technology and tries to either use or emulate it.
