As Steam Deck’s APU is being segmented into Semi Custom category, I have decided to create a thread specially to discuss about current and upcoming custom APU from AMD. Below is the comparison chart for all sub-$300 gaming consoles using custom APU

As listed, AMD APU has been pretty successfully at catering sub-$300 gaming console market. Below is my take on upcoming gaming consoles:

Steam Deck 2
  • Most of the info is from MLID; the new APU is codenamed Little Phoenix which is derived from upcoming Phoenix Point from AMD with lesser CPU and GPU cores
  • With Zen4 and RDNA3 features, the upcoming Steam Deck 2 might be getting double performance than current one
  • The only issue is stock availability, AMD has just started moving the whole desktop, laptop and server CPU not to mention RDNA3 GPU to TSMC N5/N4 process, so don’t expect Steam Deck 2 ready before end of 2023?
Steam Console
  • Well, Steam Console is not mentioned by any rumour as I know, but based on my observation Valve definitely will discussion with AMD to create custom desktop APU to combat with Xbox Series S and PS5 Slim. Remember Steam Machine?
  • The best candidate most likely based on desktop version of Phoenix Point with GDDR6 support
  • The issue again is foundry limitation, that’s why my expectation date would be 2024 unless…
  • AMD backporting the new APU to 6nm since TSMC now has more availability room on N7/N6 process than N5/N4 process

PS5 Slim
  • Unlike past transition from PS4 to PS4 Slim which came with die shrinking form 28nm to 16nm and using much lesser power, the PS5 Slim would be using 6nm designed APU similar to Xbox Series S Refresh
  • Of course Sony will custom some features just like PS5

Xbox Series S Refresh
  • Current Series S APU is made on TSMC N7 process with 197 mm2 die size and 8 billion transistors. With one additional layer on EUV mask, we can expect smaller die and more APU per wafer from AMD
  • The current Series S might get price cut to US$199?
  • If Microsoft continue selling the current Series S @ $199, we can expect more features for upcoming Series S: likely with more CU and higher clock speed?
  • Microsoft wants to sell as many Xbox as possible cause the success of Xbox Game Pass depends on it.

Mac Mini
  • Mac Mini might not exactly apple to apple comparison here but we can actually learn about the power of N5 process here: with doubling transistors and much smaller die size, M1 is really leading in process technology
  • Apple is really profit oriented company. You can buy 2 units of Xbox/PS5 Slim units with money left
  • That’s why Apple is reluctant to enter the gaming console market
  • But Apple actually has another lineup that can really compete with sub-$300 market indirectly. That’s is iPad lineup and it is matter of time before Apple putting M1 into base iPad with 64GB storage @ $329 (with 256GB the price bump to $479 provided Apple maintain the ASP)

Interesting thread, but let's see each current point:
1. Steam Deck 2 it might be a real fact. But expect it to happen in at least 2 years more. Steam Deck 1 is still getting customers.
2. Steam Console... sorry, I can see a special dock for SD2 to make it useful as a console.
3. PS5 Slim is interesting. I can see only do a node shrink for it from 7 nm to 6 nm.
4. Similar thing with XBox.
5. No way it happens with Mac.

Your table is a bit odd. The Steam Console doesn't exist, the Mac Mini isn't a games console, and I don't see why you included a PS5 shrink but not an XBox Series X shrink.

One thing that I wish we had seen was an XBox One handheld. You could replace the 256-bit DDR3-2133 with a 128-bit LPDDR4X-4266 interface, and otherwise just do a straight shrink to 6nm. Getting the whole XBox One game catalogue on a Steam Deck (or Switch!) sized console would be awesome, and it would double up as a great device for streaming games from XCloud.

The only thing not [redacted] about everything MLID said in this video is that PHX2 exists. And that's been known for a long, long, looooooooooooooooooooong time now.

I'm not denying that there will be a Steam Deck 2, but I can tell you for certain it will not be using PHX2, nor are the specs that MLID listed for PHX2 correct either.

I personally believe that Valve will stay far, FAR away from any purpose built console in the future. At the very best, we might get a new update for a semi usable SteamOS for desktops. There will be a decent number of ultra small form factor desktops that ship with Rembrandt APUs next year that will make for excellent substitutes.

6nm is nice for making full fat versions slightly smaller and cheaper to produce but you won't see PS5 and XSX slim before 5nm die shrinks. maybe end of 2023 if we are lucky.
kind of same with steam deck 2. will get probably when production of 5nm node is plentiful and not fully booked with higher margin/volume chips (server, DIY, GPU, consoles)

The only accurate things here would be the PS5 die shrink abs the Steam Deck. While the Steam Deck 2 was somewhat confirmed, there are no specs for it yet because Valve hasn’t even begun the design process.

Apple TV is Apple’s console, not the Mac Mini.
