League Of Legends: CPU Benchmarks
Lastly, we're testing a handful of CPUs to gauge this title's dependence on platform performance. What does it take to avoid a bottleneck?
Seeing that a dual-core Athlon II X2 260 manages to stay above 90 FPS at all times, it's a safe bet that LoL players don't have much to worry about as far as processor-based limitations are concerned. Any dual-core CPU above 2 GHz is probably a safe bet for smooth frame rates.
Remember that the mobile AMD A10-4600M (2.3 GHz base clock) and Intel's mobile Core i5-3210M (2.5 GHz base clock) are both able to keep frame rates above 35 FPS using weaker on-die graphics engines at this title's highest detail settings and a resolution of 1920x1080.
