Core i7-8550U


Description
The Core i7-8550U is a cpu manufactured by Intel that was released on August 2017. This model has 4 Kaby Lake-R cores with HyperThreading, runs at 1800 MHz as base frequency and has a a thermal design power of 15 W.

The i7-8550U has 4x32+4x32 kB of cache L1, 4x256 kB of cache L2 and 8192 kB of cache L3.

The first Kaby Lake CPU was released in August 2016. It uses a 14 nm process and was the first architecture in breaking the previous tick-tock model. Actually, it is not that different from the preceding Skylake: it has 64kB of L1 cache and 256kB L2 cache per core.

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.
