The Ryzen 7 5800 is a cpu manufactured by AMD that was released on January 2021. This model has 8 Vermeer cores with Simultaneous MultiThreading (SMT), runs at 3400 MHz as base frequency and has a a thermal design power of 65 W.
Zen 3 uses TSMC’s 7nm process, still uses the AM4 socket and has up yo 32MB of L3 cache per CCX.
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.

AVX2 optimized benchmark
The benchmark in mode III (AVX2), like AVX1, is optimized to used 256 bits registers beside the second version of the Advanced Vector Extensions (AVX). The first AVX2 compatible CPU was released in 2013.
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.
