Gaming performance

Let's see how good Core i7-2677M and Core M-5Y31 are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i7-2677M

Turbo Boost 2.0 (dynamically manages an Intel CPU's voltage and core frequency, allowing them to exceed rated values for short periods of time)
Trusted Execution (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
AES (Advanced Encryption Standard instructions set - hardware acceleration of AES encryption and decryption. Speeds up encryption software, e.g. Veracrypt)
Anti-Theft (Anti-Theft enabled laptop, if equipped with a 3G module, can be blocked remotely by an SMS message when stolen)
My WiFi (allows an Intel CPU based laptop function as a WiFi router)
Idle States (a set of CPU idle states of varied depth, used for energy saving purposes)
Enhanced SpeedStep (saves energy by managing CPU frequency and voltage in realtime. Supercedes SpeedStep)
Thermal Monitorin (prevents a CPU from overheating by lowering frequency upon reaching the critical temperature)
Execute Disable Bit (allows marking some memory ranges as non-executable, thus protecting software against so-called "buffer overflow" attacks)
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 M-5Y31

Much newer (1 December 2014 vs 27 June 2011)
Finer manufacturing process technology (14 vs 32 nm)
Less power hungry (5 vs 17 watts)
AVX2 (Advanced Vector Extensions 2 - an extension to AVX, the 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)
AES-NI (Advanced Encryption Standard New Instructions - additional instructions for hardware acceleration of AES encryption and decryption)
