We’ll be evaluating the new MSI R6970 Lightning with our X58 testbed which has the following specifications:
Since the basic performance of the Radeon HD 6970 SKU has been established in our original Radeon HD 6900 series article and we've also furthered that with a Radeon HD 6900 CrossFire performance article, we've decided to cutback on the number of tests for this card rather than running the usual suite of benchmarking tests.
Since the R6970 Lightning is touted for its overclocking capabilities, we are interested to find out just how far we could push the card. We will also present results of the card in it’s overclocking state to show just how much more performance you can eke out from such a highly-tuned card. To this end, we managed a maximum stable overclocking state of 1000MHz at the core and 5600MHz DDR at the memory, which is respectable for a Radeon HD 6970.
We are also interested to find out, in stock form, how much faster would this card be than a reference one. And for comparison, we have also included results of other high-end cards such as the Radeon HD 6950 and GeForce GTX 580 and GTX 570.
