P.S. Was It really necessary to put such a big picture of M2 Pro here? The bigger the better or what?
The picture you posted before theirs is literally bigger? Maybe you have some weird image scaling bug?

The idea of pictures being too big scares me regardless, I really don't miss the old days of 56k warning tags. If it was all up to me I'd say bring on the 4k PNGs please and thank you 🙏🙏🙏.

I just checked a few easily Google-able benches: PassMark 1T, GB5 1T, GB6 1T. All about 1.25x.
Well, maybe my Google skill sucks, but generally it is far lower than 25%, closer to 18% on average.

For one the 3800X isn't on that chart. Two it includes multi-threaded tests where Zen 3 has less of an increase. Three even still the 5800X is 1.19x (100/84) on that combined metric against the 3800XT.

In the ST benchmarks the 5800X is less than 25% faster than the 3800XT.
It’s close enough, it’s fair to say it’s >=20%. In the stuff that really matters (loading JavaScript bloat) it hits 25%.

The context missing is that 2700X -> 3950X -> 5950X -> 7950X there was always an fmax increase. The fmax went from 4.35ghz -> 4.7ghz -> 4.9ghz -> 5.7ghz. For Zen 5 it will be the first fmax regression.

My point just being that Zen2 to Zen3 is not 25% or more in ST on average, 20% is still mighty impressive especially when you compare to the competition.

That's not top SKU vs top SKU.
Never do that.

Here the 5950X is 20% faster than the 3800XT in ST CB R20.

My point being that zen3 is more often ~20% faster than the zen2 than 25 in ST.

But all in all it is really not that important, to continue this discussion.

Zen2 -> Zen3 had a 19% increase in IPC (on average) and 4.255% increase in max frequency, so 24% ST increase overall. Pretty close. Zen3 could also maintain it's ST turbo much better than Zen2 so most likely the increase is effectively higher.

Edit: Anandtech showed a 32% ST Spec integer performance increase and 25% ST Spec floating point performance increase. So actual single thread performance increase was indeed 25+%.

The what?

Edit: I thought that was a typo. In fact, a quick Google search reveals there was a CPU called the 3800XT.
