The new Core i5 6xx and Core i3 5xx series of processors are now amongst the fastest dual-core processors money can buy. Even some quad-core processors fell victim to the Core i5 661, as it defeated the AMD Athlon II X4 620 in virtually every test. The AMD Phenom II X2 550 also struggled to keep pace with the Core i3 540 in most tests.
