Default First AMD Benchmarks With DDR3 Memory Spotted

Better late than never, AMD is embracing the DDR3 memory standard. Its newest desktop CPU socket, the AM3, connects the processor to dual-channel DDR3 memory. Initial specifications about AMD's processors on the new socket suggest that DDR3 1333MHz (PC3-10600) will be held as the memory standard the integrated memory controllers on AMD's processors support. The far-east team of Tom's Hardware posted the first series of benchmarks of a Phenom II AM3 processor, when paired with DDR3-1333. The benchmarks featured Gigabyte's MA790FXT-UD5P motherboard along with Corsair's dual-channel DDR3-1333 kit running at DRAM timings of 9-9-9-24. The CPU-Z window also shows that the memory modules are running unganged, meaning that the two memory controllers of the Deneb core are independent, with each controller handling a 64-bit wide memory channel. This state is somewhat comparable to that of single-channel memory, except that multi-threaded applications will still be able to independently address memory on each channel, utilizing all the bandwidth on offer.

Going from 2,6GHz to 3,1GHz they get no increase in superpi time?
And where is the DDR2 phenom to compare with?

if you ever see a system get a increase in SuperPi time when overclocking, let me know

Okay, maybe I ment decrease, although they proved they got an increase in calculation time when overclocked

seems more likely they either made a typo ?

but I agree, this test is pretty much worthless when it comes down the DDR2 vs DDR3 performance

their Wprime results are horrible, AMD Phenom II X4 at 3.5Ghz scores 10 seconds in Wprime 32M
they do Wprime 32M in 44 seconds at 3.2Ghz ? wtf most likely they forgot to run it on all 4 cores
