Just for context , Zen 4 was ~10-12% uplift with some minor tweaks versus Zen 3. If Zen 5 ends up being just 10-15% faster at iso clocks versus Zen 4*, then something went wrong in the design process. AMD has such advanced internal performance modeling tools that I find it impossible they would...
In a way that people who designed it disagree with you, and I tend to believe them more:

For Zen 1 it's a huge uplift versus previous core and a major redesign - they used bits and pieces from BD and...
Here are two average samples of Zen 4 with different L3 capacity that boost to same 5Ghz. 32MB version gets around ~5% higher integer score (on Windows).

https://browser.geekbench.com/v5/cpu/22313699
Total score.
I just checked integer scores of two STX samples:
https://browser.geekbench.com/v5/cpu/22424015
Integer Score 829 @ 2Ghz
https://browser.geekbench.com/v5/cpu/22427061
Integer Score 1011 @2.33
It looks like the second sample scores 5% better than what GB5 data...
I checked his 2G results and the scaling to 5.75Ghz is 0.952x (from a perfect 1x). Which aligns with 25% vs 30% uplift that I calculated.
You can check GB5 browser for 7500F vs 8600G ST results - it's full Zen 4 with 32MB of L3 vs Zen 4 with 16MB L3. The difference is around 5% as they boost...
Correct me i I'm wrong but 2.33Ghz sample with half od the L3 cache (16MB) scored 1224pts in ST test. If it scaled perfectly to 5.7Ghz it should score 5.7/2.33 x 1224 ~= 2994 which is 30% higher than what DisEnchantment gets ( with Zen 4 that has 2x the L3 and running an optimized bios with good...
20% in *some* MT workloads ,and 5-10% tops in ST workloads vs the old RPL-R (another slide claimed ~5% ST uplift vs RPL). My guess is it will get crushed by Granite Ridge, but let's wait and see.
They are referencing the old "news" from RGT... Not really reliable, just like MLID. I'm not saying I don't believe the numbers could end up being in the same ballpark, just that these news sources are dubious.
I still remember his BS claim about Redwood Cove having 20+% IPC increase (it has actually close to zero IPC increase)... That was a true facepalm moment. Maybe someone trolled him with that fake info as well, it's possible. The guy is just hilarious, and he still thinks he has real sources.
