Clock for clock single thread, how does the Ryzen perform?

[Byte]

I'm seeing a lot of benchmarks with random frequencies like 7700K at 5GHz, and turbo frequencies posted. The problem with turbo frequencies is you are not guaranteed that number and it can jump around. Anyone see a review with locked frequencies, preferably all at the same. Real interested in the ipc comparison.

I'd say 5~15% less depending on the application, bit of a regression due to SMT in games but that should be sorted out soon enough.

IINM, ~Haswell on average, but bounces around depending on the specific application / benchmark.

THG tested them at the same clock speeds, but had to downclock the i7's to compare, as the Ryzen chips don't reach the same clock rates.

I'd be interested to see how Ryzen compare to past AMD chips, clock for clock. Maybe just Thuban, Piledriver and Excavator.

The answer to your question, and the some :

I'd have to question the above chart, considering how they perform at the same clock rate in every day apps. Perhaps it's not as simple as IPC which determines how they perform, but in gaming and most desktop apps, when at the same clock rate, Skylake is out performing it. Perhaps it's a software issue that will get changed over time, or perhaps it's not as simple as IPC = single thread performance.
