DiRT 3 In SLI
Again, small differences in performance between Intel’s six-core offerings and its quad-core Sandy Bridge-based chips are just as likely to be tied to threading optimizations as PCI Express bandwidth. In fact, because the gaps get smaller as resolution increases, differences in processing performance again make the most sense.
DiRT 3 takes advantage of up to eight threads, though it’s not clear if it prioritizes physical cores over logical ones.
Core i7-3960X manages to score a more sizeable gain in three-way SLI at 1680x1050 and 1920x1080. The performance of all three platforms narrows at 2560x1600, though.
