Not competitive at all. It's easily visible on the laptop lines, where the same GPU manufactured on TSMC has 3 times the power/performance ratio compared to the Intel one.
Putting more cores is just another desperate move to play the benchmark. Power is roughly quadratic with frequency, every time you fall behind competition, you can double the number of cores and reduce the frequency by 1.414 to compensate.
Repeat a few times and you get CPU with hundreds of cores, but each core is so slow it can hardly do any work.
That's very interesting if it's the same GPU and perf/W is that much worse. Where are these numbers published please?
??? GPU vs CPU workloads are completely different. Comparing Panther Lake iGPU vs Ryzen iGPU is not going to tell you much about how high density server CPU performance will work out.
The Panther Lake vs Ryzen laptop performance comparisons show that Pather Lake does well, basically trading against top end Ryzen AI laptop chips in both absolute performance, and performance per watt.
