Ryzen 7 4800U vs 3800XT
Description
Both models 4800U and 3800XT are based on Zen 2 architecture.
Zen 2 is fabricated on the 7nm process from TSMC and it’s the third generation of Zen CPUs. It comes with 64kB of L1 cache and 512kB of L2 cache per core. Zen 2 CPUs are divided into 3 categories: Matisse (desktop), Rome (Server) and Castle Peak (high-end desktop).
Using the multithread performance as a reference, the 4800U gets a score of 356.8 k points while the 3800XT gets 508.9 k points.
Summarizing, the 3800XT is 1.4 times faster than the 4800U. To get a proper comparison between both models, take a look to the data shown below.

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 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.
