AMDs MCM approach for GPUs failed pretty hard...
Typically MCM will deliver much better efficiency. We saw that with Zen. However RDNA3 is completely messed up in this regard.
I wonder if AMD will go back to a monolithic design for Radeon 8000 series.
Watt usage (games, video and multi monitor usage), drivers and support (early access titles and lesser popular titles just run bad on AMD, most emulators included), features like Reflex, DLSS, DLAA, DLDSR including ray tracing and path tracing, everything is just inferior on the AMD side. Hence the lower price and still its not selling well. AMD is in full panic mode when it comes to software in general.
AMD needs to focus on low to mid-end or Intel will eat them alive with Arc in a few years. When Intel starts blasting out Arc on their own nodes and AMD still relies 100% on TSMC which will milk them dry (because of node competition). Apple and Nvidia have priority at TSMC, even Intel has more money to go 3nm before AMD is able to use it. If AMD will use TSMC 4/5n instead of 3n, money is the reason.
Starting to miss ATi, at least they focused solely on GPUs. AMD don't and never will.'
Atleast AMD fixed the massive power spike issues present in 6800 and 6900 series with 7000 series tho.
