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.

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.
