3DMark06 CPU
3DMark06 is a discontinued DirectX 9 benchmark suite from Futuremark. Its CPU part containts two tests, one dedicated to artificial intelligence pathfinding, another to game physics using PhysX package.
Cinebench 10 32-bit single-core
Cinebench 10 32-bit multi-core
Cinebench 11.5 64-bit single-core
Cinebench R11.5 is an old benchmark by Maxon, authors of Cinema 4D. It was superseded by later versions of Cinebench, which use more modern variants of Cinema 4D engine. The Single Core version loads a single thread with ray tracing to render a glossy room full of crystal spheres and light sources.
Cinebench 11.5 64-bit multi-core
Cinebench Release 11.5 Multi Core is a variant of Cinebench R11.5 which uses all the processor threads. A maximum of 64 threads is supported in this version.
WinRAR 4.0
WinRAR 4.0 is an outdated version of a popular file archiver. It contains an internal speed test, using 'Best' setting of RAR compression on large chunks of randomly generated data. Its results are measured in kilobytes per second.
x264 encoding pass 1
x264 benchmark uses MPEG 4 x264 compression method to encode a sample Full HD (1080p) video. Pass 1 is a faster variant that produces a constant bit rate output file. Its result is measured in frames per second, which means how many frames of source video file were encoded per second.
x264 encoding pass 2
x264 Pass 2 is a slower variant of x264 video compression that produces a variable bit rate output file, which results in better quality since the higher bit rate is used when it is needed more. Benchmark result is still measured in frames per second.
TrueCrypt AES
TrueCrypt is a discontinued piece of software that was widely used for on-the-fly-encryption of disk partitions, now superseded by VeraCrypt. It contains several embedded performance tests, one of them being TrueCrypt AES, which measures data encryption speed using AES algorithm. Result is encryption speed in gigabytes per second.
Geekbench 2
Passmark
Passmark CPU Mark is a widespread benchmark, consisting of 8 different tests, including integer and floating point math, extended instructions, compression, encryption and physics calculation. There is also one separate single-threaded scenario.
Mining hashrates
Cryptocurrency mining performance of Core i7-2640M. Usually measured in megahashes per second.
Game benchmarks
Let's see how good Core i7-2640M is for a gaming PC, compared with system requirements of some popular titles. Remember that sometimes official hardware requirements may reflect real performance inaccurately.
Relative perfomance
Overall Core i7-2640M performance compared to nearest competitors among notebook CPUs.
AMD equivalent
We believe that the nearest equivalent to Core i7-2640M from AMD is Turion 64 MK-38, which is nearly equal in speed and higher by 8 positions in our rating.
