amd processors

[bigKr33]

Ok here it goes. Amd's are typically clocked around the 2ghz range, but heres where the real confusion comes in for me. An amd 3700 san diego core is clocked at 2.2ghz, so does that mean the 3700 means 3700mhz, but its clock is 2.2ghz. Are cpu speeds kind of like gpu speeds (in perspective), example a video card usually shows (for specs) mem. speed, and core speed, is it the same priciple with cpus for amd's, 3700mhz core, and 2.2ghz clock for....well i don't know for this one. Please help me. I've always wondered, but now i feel its time to get some answers.

It's 2.2ghz. The 3700 is a model #.

 

[bigKr33]

So its just a model number. Cool, i really didn't know it would be that simple, lol

Back when they first started the 2000 series chips, they were suppose to basically equal the performance of a P4 chip that ran at that speed.
For instance, 2200+ @ 1.8 GHz was ~ equal to a P4 at 2.2 GHz.

Now that Intle has stopped increasing their chip speeds and both have gone to dual core chips, this no longer really holds true.

Just know that a 3700+ perfroms better than a 3500+, which performs better than a 3200+, etc.

Yeah, its a bit misleading. They are named that way so that less informed customers will know about how it compares to the intel counterparts.

Yeah because comparing a 2.2ghrtz AMD Athlon 64 3700+ 1MB 90nm Rev. E San Diego 939pin, to a INTEL P4 Pentium 4 670 3.80GHZ 800 FSB 2MB L2 CACHE HYPER THREADING LGA775 LGA-775 SOCKET Processor CPU to a AMD 2.0Ghrtz X2 3800+ dualcore with 512K L2 cache per core Rev. E Manchester 939 pin with X86-64bit extensions to a Intel LGA 775 Pentium D 2.8GHz 820 800MHz FSB 2x1MB L2 Cache Dual Core EM64T isn't too difficult.

For AMD procesors of the same family and socket the amount of L2 cache as well as the speed determine the model number.

AMD Athlon 64 X2 (dual-core)
Model Frequen L2 Cache
4800+ 2.4 GHz 1MB + 1MB
4600+ 2.4 GHz 512KB + 512KB
4400+ 2.2 GHz 1MB + 1MB
4200+ 2.2 GHz 512KB + 512KB
3800+ 2.0 GHz 512KB + 512KB

AMD Athlon 64 FX
Model Frequen L2 Cache
FX-57 2.8 GHz 1MB
FX-55 2.6 GHz 1MB
FX-53 2.4 GHz 1MB
FX-51 2.2 GHz 1MB

AMD Athlon 64
Model Frequen L2 Cache
4000+ 2.4 GHz 1MB
3800+ 2.4 GHz 512KB
3700+ 2.2 GHz 1MB
3500+ 2.2 GHz 512KB

This seems more reasonable than the Processor Numbers that Intel introduced when they hit the wall somewhat below 4 GHz.

Can you make sense of these Intel Processor Numbers?
Pentium D & EE (dual core): 820, 830, 840
Pentium 4: 670, 660, 650, 640, 630
Pentium 4: 571, 570J, 561, 560J, 560, 551, 550J, 550, 541, 540J, 540, 531, 530J, 530, 521, 520J, 520
Celeron D: 351, 346, 341, 336, 331, 326, 350, 345, 340, 335, 330, 325, 320, 315

The Athlon model numbers used to indicate how the chip would perform relative to an Intel chip. For example a 3000+ was supposed to be roughly equivalent to a 3.0 GHz Intel chip. However, Intel stopped increasing clock speeds at the 3.8 GHz mark, so any value above 3800+ is just for internal comparison amongst other AMD chips. Basically:

For all model numbers <= 3800+, it indicates the chip's performance relative to Intel chips.

For all model numbers > 3800+, it indicates the the chip's performance relative to other AMD chips.

It's called PR Rating but most people believe it to be the Pentium Rating but in fact it means Performance Rating. Yep... it's misleading to a degree alright. Don't worry about the 2.2g clock speed. It's not all about how many cycles a cpu can run, it's how much it can do per cycle. Roll a tricycle tire one revolution and then do the same with a car tire tire. You would need many more revolutions with the trike tire to match the distance covered with the car or truck tire. Now you know the difference between a Celeron and a P4, AMD XP or A64. Pretty simple once you take the marketing gimmick out.

the numbers like 3700+ etc were originally supposed to indicate how an athlon would compare to a similar p4 processor... for example: athlon 3700 is only 2.2ghz but should perform similar to a p4 3.7ghz... back in the day with athlon XPs that kinda worked not sure how accurate it is nowadays...
