Gaming performance

Let's see how good Core i3-2312M and Core i5-520M are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i3-2312M

0.2% faster in synthetic tests
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)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
Quick Sync (hardware acceleration of video encoding and decoding for Intel CPUs. Speeds up video encoding by times, but at the cost of somewhat lower quality)
Virtualization (Hardware acceleration of virtual machines)

Advantages of Intel Core i5-520M

Enhanced SpeedStep (saves energy by managing CPU frequency and voltage in realtime. Supercedes SpeedStep)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
TXT (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
vPro (a marketing umbrella term for several Intel technologies: AMT, TXT, EDB, VT, Anti-Theft and some others)
AES-NI save
