Not directly related to Switch but it looks like AMD is working on Van Goh's APU (potentially Steam Deck's successor), and it could be based on the upcoming Phoenix design (the APU would be for low power gaming laptops ).
Long story short, 4 core/8 thread Zen 4 CPU and RDNA 3 GPU with higher clock speeds (4GHz CPU and +2Ghz GPU) Can also get the 128 bit controller LPDDR5 or even lpddr5x (102-133GB/s bandwidth) with potentially 50% more CPU power and 60% more GPU power than the Steam Deck, and even up to 50% more bandwidth. CPU and GPU clocks will be like 25% higher but there will be new architecture efficiencies as well to boot which brings it to 50-60% more power overall.
It's expected to be released in late 2023 or early 2024 on a 4nm node (from Stream Deck's 7nm APU) with the die size of 110-150mm^2
This reminds me a lot like the 20nm tx1 to 16/12nm Mariko jump... or at least Mariko could have easily been a 50% bump in CPU and GPU with the same clock speeds..
But anyway, would be interesting to see Steam Deck 2's power draw at 4nm TSMC... Would it be able to hold the same power draw as steam deck or better? Even though we never really saw 1.6 TFLOPs in steam deck in action.. 2.56 TFLOPs at 15 watts handheld would be a sight to behold.
AMD is working on its Van Gogh SOC successor that shares a design similar to Phoenix APUs & targets next-gen Steam Deck handheld console.
