I did some quick math regarding the spec numbers from Rocket Lake preview on AT and the performance per clock almost perfectly matches the result AT got when they reviewed Zen3 . Zen3 has around ~15% higher ST integer IPC than Cypress Cove and around ~8% higher ST fp IPC in SPEC2017 rate-1 benchmark suite.
This is almost a perfect match to the Zen3 deep dive results, the only difference is that Cypress Cove has a bit lower performance than WC and is in the middle, basically (between IL and WC).
Below is the chart from Rocket Lake preview, if you adjust Zen3 scores for 4% deficit in clock speed you get the numbers I posted above, almost a perfect match:
So to sum it up, inferior IPC(and not a by a small amount!), worse latency due to (most likely) physical implementation compromises in the cache subsystem, somewhat higher clock speeds but nothing to write home about and extremely bad power draw. Gaming performance suffers due to worse latency than intel 10th gen but lets see the final firmware results. I doubt there will be much of a change, probably +-3% at best. They seem SOL in every workload except AVX512 and pricing is really out of touch with reality (even if you count in the scalper tax right now).
I do get the urge to launch SOMETHING new, but it kinda loses the point if it's so inferior. Looking back at their slides, if all they could show for gaming was ~4% higher numbers in their pre-selected few titles under murky test conditions, that was a tell tale sign of desperation .
