Zen 4 has slightly higher IPC than Golden Cove so the numbers track with the above calculation, roughly speaking at least. There’s basically no way Zen 5 gets that low of an increase unless AMD completely botched something. The far more plausible answer is that it’s just that the score is an ES on an immature platform that is limiting performance.
Zen 5 is to wide to have lower ipc increase tham zen 4 over zen 3

Especially when all prior Zens were 6 wide front ends and it's now 8 wide...if they bother to change something that big, I really don't get how they'd get a tiny tick level increase.

Or maybe the meme was just a way to cope and it's really Zen 5%.
Wait for 0ther benchmarks.. geekbench can be easily tricked as chips and cheese showed

I can literally see the timestamp on the entries.

It's about time to pull the curtain on your make-believe.
?
It's okay, 2026 will be your year!
If the 1.4 GHz score is legit, I get roughly 70% IPC increase in integer. Seems too good to be true but we’ll see soon enough I guess.
Remember that IPC/freq scaling isn't quite linear.
So at prod clocks it'll be lower.

cpupower set-frequency doesn't seem to work on Zen 4. So I can't get 2000MHz results.

And while it's fun I'm pretty sure it's pointless to compare to possibly accurate GB5 results at nowhere near retail clock speeds.

Does bash not ask you to install it?

Benchmarking on Linux comes with all sorts of interesting caveats tbh. Performance may vary wildly depending on the cpu governor, scheduler, kernel timer frequency, you name it.

I was able to achieve swings ranging from -50% up to +15% of 1T performance in GB5 by tweaking these things on my old Whiskey Lake laptop compared to stock settings.

yeah Linux benchmarking is a mess outside of shelf stable server platforms.
