Have the differences in IPC and single core perf. been overstated in games, between Zen 3 and Golden Cove?

My 12900k can get 927 cpu z ST with e cores on btw.

What speed do P cores at and what can ring clock boost to on auto??

I know ring clock can still boost high with e-cores on as long as they are completely unused and it is on auto. But if an e-core is even used a slight bit, ring clock tanks to 3600MHz. But I have seen ring clock boost to 4600MHz if e-cores are on, but not called on.

5.6 ghz on 3 pcores. Can do 5.7 but it gets toasty, hitting 85c on the 3 cores that boost that high. Cache is on auto, don't think it affects cpu z

So, 4600mhz or higher is possible, and clocking it higher improves the single threaded performance?

I would imagine that the Zen ring cache is about the same as the average clock speed? So, Zen 4 will probably have a ring/cache clock of 5ghz or more?

Games not showing that difference probably has more to do with being GPU bottlenecked even at 1080P

I'm doubtful about that, in the Techspot review they used a 6900XT, easily enough for 1080p. In most games, the minimum FPS is similar between Zen 3 and Golden Cove. The minimum FPS (10 game average) was 147 for the 5800X and 151 for the 12700KF, both operating at stock settings.

Notably, in some games like Horizon Zero Dawn, the 5800X has 130 min FPS and the 12700KF had 122 min FPS. In Watchdogs:Legion, Rainbow Six and Shadow of the Tomb Raider, the 5800X was slightly ahead. It's probably true though that you'd see more of a difference in CPU performance in games like Cyberpunk, at 720p resolution.

Will be interesting to test once faster video cards come out. We will not really know as how do we know the video card and CPU are both not bottlenecked in certain situations making the gap smaller as its possible that the 1% lows cannot be any higher no matter Zen 3 or Golden Cove with current video cards in certain spots of some games??

The test will be interesting once Radeon RX 7900 XT and GeForce RX 4090 come out in a few months.
 
Even at 720p, the difference in framerate between the Zen 3 CPUs with 8-16 cores and the 12700K is around 7-8%, in Techpowerup's review:

Intel Core i7-12700K Review - Almost as Fast as the i9-12900K

With the Core i7-12700K, Intel has released a formidable competitor to AMD's Ryzen 5800X and even 5900X. Thanks to eight powerful Golden Cove cores, the processor handles all workloads very well, including gaming. Compared to the i9-12900K, it runs almost as fast, but much cooler, with better...

At 1440p, the difference on average framerate falls to around 4%, which I think for most, the difference would be quite hard to distinguish.

I think what this shows, is that there's not an exact correlation between IPC and game performance (there's other factors involved like cache, core count to a lesser extent), otherwise we would expect around 20% higher minimum and average framerates in most games, at lower resolutions.
