Ryzen 9 5900X vs 5900HX
Description
Both models 5900X and 5900HX are based on Zen 3 architecture.
Zen 3 uses TSMC’s 7nm process, still uses the AM4 socket and has up yo 32MB of L3 cache per CCX.
Using the multithread performance as a reference, the 5900X gets a score of 840.1 k points while the 5900HX gets 421.1 k points.
Summarizing, the 5900X is 2 times faster than the 5900HX. 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.
