But it repeats the 0.9.0 test on the new hardware. So the first big jump is a hardware change, but the second jump is the software changes.

It also appears to be reporting whole-CPU vs. single thread, 1.3 GB/sec is not impressive for single thread perf

Agreed. How hard is it to keep hardware fixed, load the data into memory, and use a single core for your benchmarks? When I see a chart like that I think, "What else are they hiding?"

Folks should check out https://github.com/dathere/qsv if they need an actually fast CSV parser.

I mean... A single 9950x core is going to struggle to do more than 16 GB/second of direct mem copy bandwidth. So being within an order of magnitude of that seems reasonable

4 generations?

5950x is Zen 3

9950x is Zen 5

Sine Zen 2 (3000) the mobile CPUs are up by a thousand respectively to their desktop counterparts. edit: Or Nx2000 where N is from Zen N.

And even with 2, CPU generations aren't what they used to be back when a candy bar cost less than a dollar.
