Gaming performance

Let's see how good Core i7-2700K and A8-6600K are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i7-2700K

Less power hungry (95 vs 100 watts)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)
HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
Thermal Monitoring Technologies
IdentityProtectionTechVersion
QuickSyncVideo

Advantages of AMD A8-6600K

61.5% faster (about 1.5 times) in synthetic tests
Much newer (4 June 2013 vs 24 October 2011)
Cheaper ($142 vs $514)
3DNow! (older SIMD instructions set used by AMD CPUs. Supercedes MMX, works with 64-bit registers)
AMD64 (AMD CPUs 64-bit architecture. Almost identical to Intel 64, save for some little and rarely used nuances)
Virtualization (Hardware acceleration of virtual machines)
