16-core Zen 5 CPU achieves more than 2 TFLOPS FP64. So number crunching performance scaled very well.
It is weird, that the best consumer GPU can 4 TFLOPS. Some years ago GPUs were an order of magnitude and more faster than CPUs. Today GPUs are likely to be artificially limited.

These aren't realistic numbers in most cases because you're almost always limited by memory bandwidth, and even if memory bandwidth is not an issue you'll have to worry about thermals. Theoretical CPU compute ceiling is almost never the real bottleneck. GPU's have a very different architecture with higher memory bandwidth and running their chips a lot slower and cooler (lower clock frequency) so they can reach much higher numbers in practical scenarios.
It's useful comparison in terms of achievable performance per transistor count.
