15% IPC boost is mildly disappointing.

It will be significantly slower in ST than M4, and even more so against the M4 Pro/Max.

I wouldn't be sure about that. Isn't apple silicon performance mostly benchmarked using Geekbench?

AMD claims +35% IPC improvements in that specific benchmark, due to improvement in the AVX512 pipeline.

AMD claims +35% IPC improvement in AES subtest of Geekbench 6. It's not the entire Geekbench 6 CPU suite. It's deceptive.

Overall GB6 improvement is likely around 10-15% only because that's how much IPC improved while clock speed remains the same.

Apple themselves have around 10% IPC uplift with M4 too.

The real issue is that most code people run doesn't use very much SIMD and even less uses AVX-512.

How come is a 15% IPC increase generation for generation a disappointing result? There might be greener pastures, I agree, but a 15% increase year over year for the quality factor of a product is nothing to be disappointed of. It's good execution, even more so in a mature and competitive sector such as microelectronics.

It's not year over year. It's 2 years.

It's disappointing because M4 is significantly ahead. I would expect Zen to make a bigger leap to catch up.

Also, this small leap opens up for Intel's Arrow Lake to take the lead.

Actually from Zen 4 to Zen 5 there is a little more than one year and a half (supposing that they will indeed go on sale in July), almost matching the AMD announcement done around the launch of Zen 4 that they will shorten the time between generations from 2 years to 1 1/2 years.

Process node advantage is real.

[aurareturn]

Of course it's real. But not only is M4 significantly faster in ST, it'll probably 3-4x more efficient than Zen5 mobile just like how M3 is against Zen4 mobile.

This difference in efficiency cannot be explained by node advantage alone as N3E vs N4 is probably around only 15-20% more efficient.

I wonder how much of the performance delta there is the OS. The performance benchmarks for Zen won't be running on OSX, credible risk they're running through the overhead of Windows.
