AMD Venice v. San Diego Core Performance in Linux Platform
Date: Tuesday, October 25, 2005 @ 19:31:14 EDT

For our performance comparison, we used an AMD 3700+ San Diego (2.2GHz) and a 3200+ Venice (2.0GHz). To compare the cores at the same frequency, three frequencies of 2.0 (200x10), 2.2 (220x10), and 2.6 (260x10) GHz were used. To achieve such frequencies for the San Diego, the VCore remained 1.414V for all three frequencies; on the other hand, for the Venice, a voltage bump to 1.586V was required to obtain 2.6GHz.

? The RAM used was a pair of 512MB Corsair XMS PC3200C2 v1.1 (Winbond BH-6 chips), and the memory timings were maintained at 2-2-2-5 throughout the test. To achieve such timings, we kept the VDimm at 3.0V for 200 HTT, 3.2V for 220 HTT, and 3.6V for 260 HTT. To make sure the memory ran stable, we ran Memtest86 extensively prior to running all the benchmarks to make sure it was free from errors. The CPU was cooled by a Thermalright XP-90 with an Enermax 92mm fan, while a 92mm fan above the modules actively cooled the memory as well. The video card used was a XFX GeForce 6600GT left at stock core and memory speeds.
