Core i7-6600U


Description
The Core i7-6600U is a cpu manufactured by Intel that was released on September 2015. This model has 2 Skylake-U cores with HyperThreading, runs at 2600 MHz as base frequency and has a a thermal design power of 15 W.

The i7-6600U has 2x32+2x32 kB of cache L1, 2x256 kB of cache L2 and 4096 kB of cache L3.

Sky Lake is also known as 6th generation Core. Include Thunderbolt 3.0, SATA Express and Iris Pro graphics with DirectX 12. It uses LGA 1151 socket for mainstream models and LGA 2066 for X-Series. Sky Lake comes with AVX2 support in all mainstreams CPUs and AVX-512 in some high end models.

Non-optimized benchmark
The benchmark in Mode 0 (FPU) measures cpu performance with non-optimized software. It uses the basic µinstructions from the i386 architecture with the i387 floating point unit. This mode is compatible with all CPUs so it's practical to compare very different CPUs

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.
