Gaming performance

Let's see how good Xeon E5540 and Xeon E5-2609 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Xeon E5540

3.1% faster in synthetic tests
Cheaper ($30 vs $143)
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 E5-2609

Finer manufacturing process technology (32 vs 45 nm)
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
