DDR2 vs DDR3: The Battle of Latency vs. Bandwidth - Asus P5K3 Deluxe WiFi & Corsair TWIN3X2048-1333C9DHX Review - PAGE 12 William Henning - Thursday, July 5th, 2007
Doom 3 may be an old benchmark, but I still really like it.
We keep seeing the same result - DDR3-1333 is just a bit slower than very low latency DDR2-1066; and that DDR3 starts to take off at over 1500MHz. The less we say about the performance of DDR3 at under 1333MHz the better, and I cannot in good conscience recommend that anyone get DDR3 memory at lower speeds than 1333MHz
Quake 4
Quake 4 is a bit more latency bound than Doom 3, but as we've observed, DDR3-1333 performs well.
