Everyone knows that more blue lights == more fastar.
Out of curiosity I ran some benchmarks on my two machines to see which came out ahead. I was assuming that a "3800+" would have more grunt than a "3.06ghz" chip (even though the AMD runs at a lower clockspeed). I was also assuming the AMD chip would run circles around my Intel one when it came to memory bandwidth - if only for the fact one runs PC3200 and the other runs PC2700.
For a Dhrystone benchmark the AMD jumps ahead by 20.32% which is consistent with a 23% difference between 3066 and 3800 ratings.
However, for a floating point Whetstone benchmark the AMD chip dropped nearly 3% - other SSE2 based FP benchmarks show between that and 30% drops for the AMD. Based on my bencmarks it seems the AMD Athlon sucks at floating point...
RAM Bandwidth tests were slightly more favourable towards the AMD. The PC3200 in my new machine pushes over 4.5gb/sec transfer rates - an impressive jump of 92% over my older machine [oh]
Ultimately these results probably mean nothing. My understanding is that SSE/SSE2 has always been Intel oriented, so maybe these tests were skewed in Intel's favour to start with. I've read about AMD having a superior memory interface on their chips (no idea if that includes mine) but equally I've no idea if I've benchmarked the RAM, the CPU or both...
In other news, I'm working on some code that'll convert a D3DX9 mesh to a D3DX10 one. Seems that the D3DX10 library is still no where near as complete as the more mature D3DX9 library, so if I can hook the two together then that makes things easier [grin]
