7900X equivalent 9900X has 120W TDP as opposed to 170W. Is it that much more power efficient?

Surprisingly not that much to be excited about IMO. AMD isn't using TSMC's latest node and the CPUs only officially support DDR5 speeds up to 5600MHz (yes, I know that you can use faster RAM). The CPUs are also using the previous-gen graphics architecture, RDNA2.

15% IPC boost is mildly disappointing.

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

That 170W TDP was chasing the benchmark crown. The 7950X lost <5% MT perf when run at 120W.

It's because x86 chips are no longer leading in the client. ARM chips are. Specifically, Apple chips. Though Qualcomm has huge potential leapfrog AMD/Intel chips in a few generations too.

Faster GPU is reserved for APUs. These graphics are just here for basic support.

Until ARM has a proper UEFI support, it's not a practical desktop/server with a few notable exceptions (Mac, Raspberry Pi) and only because there's so much support from the respective vendors.

I know that there's some work happening about UEFI+ARM (https://developer.arm.com/Architectures/Unified%20Extensible...), but its support is very rare. The only example I can recall is Ampere Altra: https://www.jeffgeerling.com/blog/2023/ampere-altra-max-wind...

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.
