PCMark2004 is an application-based benchmark and tool for measuring overall PC performance. Results seem to scale more with Memory and System MHz with little penalty for higher latency.
The aging 3DMark2001SE is a DirectX 8.1 Benchmark that in my opinion more closely conveys the performance potential in our systems. To explain, increases in many facets of your computer contribute to its ability to provide a compelling gaming experience beyond just a graphics card. 3DMark2001SE I believe is the best Futuremark product to gauge overall system performance.
That said, we see small but appreciable gains as HTT and Memory speeds increase. At 275MHz the tighter timings alone are responsible for a respectable 414pt gain. While not earth shattering, and probably would not effect real world situations in gaming to a great extent. I'll take the speed gain with the relatively simple bios adjustment to memory timings provided stability isn't compromised, which it was not. There is no error in the above graph, as stated in system setup section, 3DMark2001SE would not complete at 285MHz/3.135GHz.
Doom3 continues with results follow previous trends set. Scores at 275MHz and Cas 2.5 3:3:7 are higher than those at 275 2.5 4:4:8, with the highest score belonging to the higher CPU and memory speeds at 285MHz HTT. Even at 640x480 and low detail I still consider Doom3 to be graphics bound, but I include it to show influences of memory speed, latency, and overall system speed on frame rates with this new, apocalyptic, and entirely frightening game.
Onto our conclusion ->
