Gaming performance

Let's see how good Xeon W3580 and Xeon E3-1220 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Xeon W3580

Cheaper ($215 vs $395)
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)

Advantages of Intel Xeon E3-1220

0.7% faster in synthetic tests
Finer manufacturing process technology (32 vs 45 nm)
Less power hungry (80 vs 130 watts)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
AES-NI save
