A few comparisons just from a gaming PC with a 9800X3D (8C16T 5.2 Ghz Boost).

7 Zip benchmark

9800X3D 130 GIPs compression, 134 GIPs decompress.

C8A 21577 MIPs (21.5GIPs) compression, 9868 MIPS decompression (9.9GIPs).

Geekbench 5

9800X3D 16975 multithread, 2474 single thread

C8A 4049 multithread, 2240 single thread

A desktop class CPU is definitely quicker single threaded and multithreaded, no surprises there most of these are dual core. The single threaded performance of the C8A is actually pretty good but its also the best of the bunch by a wide margin most of the CPUs are far behind. Memory performance appears to be attrocious all around.
