The world will probably never see a newly designed, single core CPU of any architecture.
I wanted to know what is the fastest single core x86 CPU produced by both AMD & Intel.
I don't want to include running a single core (Turbo Boost) of a multi core CPU, either.
I will try and include both Opteron and Xeon server chips but I don't know enough about those.
Of the existing single core CPU's for sale I don't think you can count the
AMD Sempron 140 / 145 (Sargas) since despite AMD's marketing it as a single core it will actually unlock to a Athlon X2 4400E CPU.
Intel has the Celeron 430 Conroe-L LGA775 @ 1.8GHz with 512Kb L2 Cache but at that speed I don't think it would qualify for the fastest if it is truly a single core Core 2.
To me it looks like on the AMD side it was the
AMD Athlon 64 FX 90nm San Diego core FX-55 and FX-57 @ 2.6GHz and 2.8GHz.
Or perhaps it was a Socket AM2 Athlon 64 Orleans 90nm or Lima 65nm?
It looks like the Orleans only went up to 2.6GHz while the Lima to 2.8GHz.
On the Opteron side I'm not sure if the full 1MB L2 Cache made either the Socket 940 Venus, Troy or Athens 1356 @ 3.0GHz the fastest?
The Intel CPU's I know less about since I avoided them at this time. It looks like its either the Prescott 2M CPU with 2MB L2 Cache 662 / 672 @ 3.6GHz and 3.8GHz.
Or could it be the Pentium 4 Cedar Mill 631 / 641 / 651/ 661 up to 3.6GHz? Wikipedia says overclockers got these up to 8GHz with liquid nitrogen cooling but I'm not asking about overclocking performance.
Maybe its a Socket 603 Xeon Irwindale chip I know nothing about? Everything I read says that the Opterons of this time outperformed the Xeon's in everything but a few benchmarks where Hyperthreading came into play, which sort of overrules my single core requirement.
Anyone who actually used these chips know which is the fastest?
