Leaked Benchmarks Indicate IPC Rocket Lake-S to be slower than AMD Ryzen 5000

One of the primary benefits of the pending Rocket Lake-S series is the fact they're based on a new architecture, that architecture would offer better IPC. A website now has fired off tests at a Core i9 11900K measuring exactly that.

The end result is that, although an IPC increase definitely is measured, Ryzen 5000 remains to be the faster architecture. IPC byw ie the number of instruction-by-clock, indicative performance per core. The asia based reviewer compares the Core i9 11900K with the Ryzen 9 5950 and that reveals the existing Ryzen 5000 chips are about 6% to 10% faster than the Rocket Lake processors when both architectures run at 4 GHz and are limited to four cores and eight threads.

IS this bad, or is it OK compared to 5800x?

Some (everyone here) say Rocket Lake sux, so it better not be good

It is cool story. Good for You. But that is far from stock. Its like testing heavy undervolted zen3 running 2000 fclk. You can dish out alot of free performance but it is far from " out of the box" experience.
Most reviews don't even use PBO on Zen3. When it is free 5-10% performance...
