AMD Performance Testing
Performance Testing : AMD Athlon64 Socket-AM2 Platform
For AMD based testing, we grabbed one of AMD's new Socket-AM2 based Athlon64 processors and paired it with the Asus M2N32-SLI Deluxe motherboard, based on the nVidia nForce 590 SLI chipset. The board supports DDR2-800 natively and allows for incredible amounts of memory module tweaking via timings and voltage alteration. Just as with our Intel based platform, we ran our first set of tests with the Kingston HyperX modules at their stock CAS 4-4-4 timings against our "generic" 5-5-5 based DDR2-667 and DDR2-800 modules.
Our AMD platform shows much better performance gains with the HyperX modules over our stock brands, both in terms of memory bandwidth and latency. At stock 4-4-4 timings, our Kingston HyperX modules have an incredibly low 70.5ns latency, compared to over 100ns for our heavily overclocked Pentium-D platform. AMD's integrated dual-channel DDR2-800 memory controller really gets the most out of these memory modules.
