Nvidia GeForce GTX 480 3-way SLI scales performance mightily

There’s a serious give and take relationship between CPU and GPU performance which can lead to bottlenecks in many situations. It would seem that the CPU is currently at a disadvantage in the pairing.

The Nvidia GeForce GTX 480  running in a 3-way SLI setup reaches impressive performance heights which may, or may not, be held back by even highly clocked processors. Guru3D has the review:

Get this, our Core i7 965X processor is overclocked at default at 3750 MHz, and man .. it’s just not enough to satisfy three GTX 480 cards most of the time. And that makes sense as it’s just such a truckload of raw GPU horsepower. I mean that’s 9 billion, yes nine BILLION transistors that need to be fed by the processor with some juicy data. The equivalent would be say roughly six GeForce GTX 285 cards. Severe CPU bottlenecks, we see it time after time in 3-way SLI setups.

One has to wonder if even a highly-clocked 6-core CPU would keep such a rig well fed with data.
