Gaming performance

Let's see how good Opteron 6376 and Xeon E5-4620 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of AMD Opteron 6376

Somewhat newer (5 November 2012 vs 14 May 2012)
Higher maximum frequency (3200 vs 2600 MHz)
Less power hungry (115 vs 130 watts)
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)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
FMA4

Advantages of Intel Xeon E5-4620

24.2% faster in synthetic tests
Cheaper ($400 vs $750)
Higher base frequency (2700 vs 2300 MHz)
Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)
TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
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
ECCMemory
