7-Zip Compressing

7-Zip Decompressing

Architectural enhancements, most notably the larger slab of directly accessible L3 cache on each CCX, result in strong performance for Zen 3 in 7-Zip compression. The 12-core 5900X is within a hair of the performance of the Zen 2 AM4 flagship 3950X. That speaks volumes about the Zen 3 architectural improvements in this workload. In case you were interested, stock versus stock, the Ryzen 9 5900X is 31% faster than the Core i9-10900K. That’s a handy beat-down from AMD!

Decompression performance shows a similar trend, but it is more core count biased. The 5900X this time cannot trade blows with the higher core count Zen 2 3950X, but it does beat the incumbent 3900XT by an 18% margin. That performance victory for the 5900X over the Intel 10900K is a massive 53%.
