AMD's Zen 3 (Ryzen 5xxx series) are beating the Apple M1 in single core score: https://browser.geekbench.com/v5/cpu/singlecore

As another datapoint Ian (of Anandtech) estimated that the M1 would need to be clocked at 3.25Ghz to match Zen 3, and these systems are showing a 3.2Ghz clock: https://twitter.com/IanCutress/status/1326516048309460992

No, they aren't. All of the top results have crazy overclocking and liquid cooling. You need to look the numbers here: https://browser.geekbench.com/processor-benchmarks. Top end Zen 3 is slightly lower than M1.

Not exactly.

You can check the clock speeds: https://browser.geekbench.com/v5/cpu/4620493.gb5

Up to 5050MHz is stock behavior for the 5950X and it's using standard DDR4 3200 memory.

Even if the Ryzen wins out, that would still be comparing a desktop CPU to a mobile one, using 105W vs 10W. It is incredible that we are making these comparisons. Apple outdid themselves.

There's going to be a AMD mobile version of the 5000 generation soon and when looking back at 4000 generation their single core (boost) performance is going to be virtually the same as the desktop variant.

Desktop CPUs differ from the mobile CPUs mainly in how much can they boost more/all cores.

In my experience mobile cpus run at about 75%-90% the single-core performance of desktop counterparts. Zen 3 APUs will be close.

Isn't the M1 fabbed on TSMC 5nm? Zen 3 is on 7nm. If a Zen 3 APU will run close to Apple Silicon I will be mightily impressed.

Best single core scores for Ryzen 2 on Passmark:

* 3800X (105W desktop) scores 2855

* 4900H (45W mobile) scores 2707 or 95% of 3800X

* 4750U (15W mobile) scores 2596 or 91% of 3800X

That's pretty good. For geekbench we see:

* 3800XT = 1357 (100%)

* 4800H = 1094 (~80%)

* 4800U = 1033 (~76%)

I would expect a 5800U to score at best around 1500, but realistically closer to 1300-1450. That's still behind the M1, but pretty darn close for being behind a node (and will still probably be faster for applications that would require x86 translation).
