790GX and SB750 explored and reviewed

Motherboards/AMD AM2+ by massman @ 2008-10-02

The 790GX chipset has been released a while ago and motherboards equiped with this chipset and the new southbridge chipset SB750 are now widely available in the local hardware shops. Madshrimps has had its sample, sent by AMD, on the testbench a while now and today we have a look at the new technology, including a better IGP and supposedly better overclocking.

SuperPi, Wprime and Lavalys everest

SuperPi and Wprime:

SuperPi has been around for ages now, but still reflects the performance of the technology. Being single threaded, you won't increase performance by inserting a quad core processor, but that's why we've chosen Wprime as an alternative. Wprime has been included in the HWBot benchmark suite for quite some time now and many people agree on the quality of the benchmark. Wprime works with multiple threads and is ideal to test multi-core processors.

Both 790FX and 790GX are performing at pretty much the same level.

Lavalys Everest 4.50

We used the memory benchmark utility to measure the performance of the memory management.

At stock speeds, the bandwidth of the 790GX setup is a bit higher than the bandwidth of the 790FX, in the overclocked test environment, the opposite is true.

Latency-wise, the 790FX is a lot better than the 790GX.
