Test System And Benchmarks

AMD Radeon HD 7970: Promising Performance, Paper-Launched
By , Igor Wallossek

Our original plan was to test Radeon HD 7970 on an X79-based platform with Core i7-3960X. However, AMD pulled the rug out from under us as our desired platform was en route to the snowy whiteness that is Canada in December. Instead, we were forced to run all of our performance data on an admittedly more common LGA 1155-based Core i5-2500K overclocked to 4 GHz. The Sandy Bridge-E-based testing will have to wait until next month, when AMD lets its next batch of information spill on the 7900-series family.
