Let's see how good Xeon E5-2623 v4 and Xeon E5-2643 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.
Advantages of Intel Xeon E5-2623 v4
21.4% faster in synthetic tests
Much newer (20 June 2016 vs 6 March 2012)
Finer manufacturing process technology (14 vs 32 nm)
Less power hungry (85 vs 130 watts)
AVX2 (Advanced Vector Extensions 2 - an extension to AVX, the set of SIMD instructions working with 128- and 256-bit registers)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)
Advantages of Intel Xeon E5-2643
Cheaper ($218 vs $444)
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)
So, Xeon E5-2623 v4 or E5-2643?
Judging by the results of synthetic and gaming tests, Technical City recommends Intel Xeon E5-2623 v4.
