Vista Ultimate x64Damn, that's a great score for a C2D and 8800 on Vista--the worst performing OS (for 3DMark01) out there!
I've noticed that there are certain CPU architectures 3DMark01 seems to really like, and Penryn/Wolfdale is one of them. In fact, in 3DMark01 they seem to be as fast per MHz as Nehalem!
PIII Tualatin, Pentium M Dothan, and Haswell are also very 3D'01 friendly. Overclocked Tualatin slightly outperforms Thoroughbred at the same clock speed. Dothan easily beats Athlon 64 at equal clock rates. And Haswell, despite being only ~5% faster than Sandy/Ivy Bridge in most modern apps, manages to be around 30% faster in 3DMark01.
I believe it may be related to the processors' cache performance. While Thoroughbred has far more memory bandwidth available to it, the L2 cache is only 256KB and 64-bits wide. Tualatin may be stuck with PC133 on an antiquated SDR FSB, but it has 512KB of very fast (256-bit) cache.
Athlon 64 has extremely fast, low latency access to main memory, but its L2 cache is only 512-1024KB in size and 128-bits wide. Pentium M Dothan, on the other hand, has a 2MB, 256-bit wide cache.
Penryn/Wolfdale CPUs may lack an L3 cache and integrated memory controller, but they have 3-6MB of extremely fast, very low latency L2 cache. Nehalem's L3 cache is a bit slower than Wolfdale's enormous L2.
While Haswell's L2 and L3 caches are similar to Sandy/Ivy Bridge, the L1 cache is twice as fast, which seems to give it an edge in 3DMark01. Unfortunately, it doesn't seem to matter much in modern applications.
I had a.. what was essentially the fastest wolfdale dual core ever, but then I did a idiot thing and ruined it 😵 At least it was only a $23 chip today. I had a E3110, which is the 6MB version of the wolfdale dual core chips, and it was stable @ 4.65 ghz with only like 1.5v v-core, and then.. I did a stupid. I tried 'lapping' it with sandpaper, did it wrong, and it only made it run hotter. It still worked fine, but it ran so hot it was idle at like 70c in windows after that and I couldn't even do much with it. I still have the chip but doubt I'll be using it for anything. So.. I picked up this E7300 off ebay for $9 used. Works great.. it's just in comparison a really, really poor overclocker, takes a whole 1.66v just to do 4ghz. Doesn't really matter on water cooling, it just won't ever clock any higher.
What's the fastest quad core chip for 3dmark 2001 for LGA775? Penryn?
