Gaming performance

Let's see how good Core i7-6950X and Core i7-7820X are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i7-6950X

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)
Enhanced SpeedStep (saves energy by managing CPU frequency and voltage in realtime. Supercedes SpeedStep)
Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)

Advantages of Intel Core i7-7820X

2% faster in synthetic tests
Much newer (26 June 2017 vs 31 May 2016)
Cheaper ($599 vs $1723)
Higher maximum frequency (4500 vs 3500 MHz)
Higher base frequency (3600 vs 3000 MHz)
x86-64 (a general name for 64-bit extension of x86 instruction set. There are AMD64 and Intel 64 versions that differ very little)

So, Core i7-6950X or Core i7-7820X?

Technical City couldn't decide between Intel Core i7-6950X and Intel Core i7-7820X. The differences in performance seem too small.
