Core i7-640LM
Performance
Description
We need your help: we don't have results in all modes. If you have a i7-640LM and want to help us to complete the stats, you just have to run the benchmark at stock frequency (no oc) in modes FPU, and validate the results. You don't have to register and the whole process will take less than 3 minutes per mode.
The Core i7-640LM is a cpu manufactured by Intel that was released on January 2010. This model has 2 Calpella cores with HyperThreading, runs at 2133 MHz as base frequency and has a a thermal design power of 25 W.

SSE3 optimized benchmark
The benchmark in mode I (SSE) is optimized for the use of SIMD instructions with 128 bits register and the SSE set up to version 3. Nearly every modern CPU has support for this mode.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.
Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.
If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
