The Core i5-8265U is a cpu manufactured by Intel that was released on August 2018. This model has 4 Whiskey Lake-U cores with HyperThreading, runs at 1600 MHz as base frequency and has a a thermal design power of 15 W.
The i5-8265U has 4x32+4x32 kB of cache L1, 4x256 kB of cache L2 and 6144 kB of cache L3.
Whiskey Lake is the third 14nm process-refinement and it’s a mobile architecture with a short list of U models.
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

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.
Test#1 (Integers) [% vs time]
Test#2 (FP) [% vs time]
Test#3 (Generic, ZIP) [% vs time]
Test#1 (Memory) [% vs time]
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.
