Gaming performance

Let's see how good Core i5-2540M and Core i5-4310U are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i5-2540M

Cheaper ($266 vs $281)
MMX (MultiMedia Extensions - the very first (1996) SIMD instruction expansion for Intel desktop CPUs, works with 64-bit registers)
SSE (Streaming SIMD Instructions - a SIMD instruction extension working with 128-bit registers)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
x86-64 (a general name for 64-bit extension of x86 instruction set. There are AMD64 and Intel 64 versions that differ very little)
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)
FMA4

Advantages of Intel Core i5-4310U

Much newer (19 January 2014 vs 20 February 2011)
Finer manufacturing process technology (22 vs 32 nm)
Less power hungry (15 vs 35 watts)
AVX2 (Advanced Vector Extensions 2 - an extension to AVX, the 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)
