Zen3 6 cores / 12 threads "5600x" -> "~15.9 average gflops per core"That sure is an interesting idea. Since the 5950X gets the best dies, you could test the limits of the architecture in terms of the highest ST/MT clocks for a specific core configuration. Then we might see what Zen 3 is realistically capable of with high-end cooling.
Compressing: 90.191 gflops
Decompressing: 100.974 gflops
Average: 95.582 flops
Zen3 8 cores / 16 threads "5800x" -> "~15.35 average gflops per core"
Compressing: 115.747 gflops
Decompressing: 129.894 gflops
Average: 122.821 flops
Zen3 12 cores / 24 threads "5900x" -> "~14.36 average gflops per core"
Compressing: 154.536 gflops
Decompressing: 190.556 gflops
Average: 172.396 flops
Zen3 16 cores / 32 threads 5950x -> "~13.53 average gflops per core"
Compressing: 182.202 gflops
Decompressing: 250.876 gflops
Average: 216.539 flops
Conclusion: as core counts go up, each core get less and less memory bandwidth resulting in lower throughput per core.
