Gaming performance

Let's see how good Core i7-2677M 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 i7-2677M

7.8% faster in synthetic tests
Much newer (27 June 2011 vs 4 January 2010)
Less power hungry (17 vs 35 watts)
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)
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)
Trusted Execution (Trusted Execution Technology - protects the system against viruses and rootkits residing in BIOS or in a boot sector)
Intel 64 (64-bit Intel CPU architecture. Almost identical to AMD64, except small and rarely used nuances)
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)
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)
AVX (Advanced Vector Extensions - a set of SIMD instructions working with 128- and 256-bit registers)
