Steam Deck 2 Ditches Semi-Custom APU for Off-the-Shelf AMD Silicon, Eyes 2028 Launch
Valve's next-generation Steam Deck 2 handheld console is reportedly planned for release in 2028, with significant manufacturing changes expected for this sequel to the highly successful handheld gaming device. According to a well-known industry leaker, KeplerL2, posting in the NeoGAF community, Valve is targeting a 2028 refresh for the second-generation Steam Deck. However, the ongoing supply chain shortages of DRAM and NAND Flash could cause disruptions to these plans, potentially leading to delays. Interestingly, this period is when the shortages are expected to start easing, so the Steam Deck 2 could still be released on time, depending on Valve's sourcing capabilities.
One of the most significant procurement shifts for the Steam Deck 2 is Valve's choice of the computing base that will power the handheld. Instead of using a semi-custom AMD APU, Valve is expected to use an off-the-shelf AMD APU that won't require any custom tuning from AMD to meet Valve's needs. This is welcome news, as the latest Steam Machine showed that Valve's reliance on a semi-custom APU solution made the hardware "obsolete" quickly while the rest of the industry advanced. With any semi-custom solution, stockpiling silicon and waiting for DRAM/NAND modules to arrive puts pressure on Valve to ship a product that is significantly underpowered or too expensive. However, with an off-the-shelf solution, Valve could use the best available option at the time of shipping and optimize SteamOS around it.For example, Valve currently uses a 6 nm APU from AMD with four "Zen 2" cores with eight threads running in the 2.4-3.5 GHz range and eight RDNA 2 CUs clocked at 1.6 GHz. Back in 2022, this was a strong specification that contributed to the Steam Deck's success in the handheld gaming market. However, if Valve were to use another semi-custom APU and face delays due to DRAM/NAND shortages, its specifications would lag behind what other companies could offer, especially as many OEMs like Lenovo, ASUS, and MSI have entered the handheld market since then. Instead, Valve will use what's currently available and best, likely involving some SoC configuration with "Zen 6" cores and RDNA 5 GPU IP. AMD offers its APUs with configurable TDPs, so Valve could take any off-the-shelf APU and adjust its power envelope to fit the Steam Deck.

45 Comments on Steam Deck 2 Ditches Semi-Custom APU for Off-the-Shelf AMD Silicon, Eyes 2028 Launch
Zen 6 - 4+8+2
RDNA5 - up to 24CU
LPDDR5 or 6
Same as the PS6 handheld... actually next gen compared to today.
that's why you can have things like ASRock's X600 boards & the Steam Machine that straight up don't have a PCH chip to handle the I/O because the I/O die on the CPU/APU handles it all
that said, I know there's the Claw out there with the 155H chip and I wonder how that one handles itself relative to all the AMD-based handhelds and if Intel would be interested to compete in that device segment
although I'll be honest, I suspect we're gonna see an increasing amount of ARM-based HHDs, Android handhelds are already there & SteamOS on ARM is coming through the Frame, if the Deck 2 is an x86 APU, I wouldn't be surprised if Valve already engaged in R&D with some Qualcomm APUs to see what kinda chip they can shove in there, put SteamOS on ARM on and get running to see what are the current limitations
if not them, then the "PC emulator on Android" devs are at least, we got CP77 running on Snapdragon 8 Elite gen5 after all...
The alternatives all feel rushed, over the top, poorly balanced, all three or one of them depending on which one you're holding; and are not supported by an OS built specifically for it.
The overall performance might be better, but then the question comes whether it really results in better playability, and more often than not, it doesn't and you'll still prefer battery life.
Steamdeck was never about being cutting edge. It always was about being energy efficient. It's also why it only has a 1280x800 screen. To save in rendering cost. The deck is extremely energy efficient up to the point I can do 10 hours on a single charge. All those of the shelf stuff and bigger screens devices can't come even close to that.
The other reason it doesn't make sense is that you make a product to go on for at least an X amount of years on it being built so you secure a contract for that so it doesn't matter if it's a customized chip or something AMD still has lying around in a drawer. The only difference is that Valve doesn't have to pay for R&D costs.
I still think Valve will partner with AMD on a customized chip and I wouldn't be surprised if it's similar to a new Embedded chip style approach. Low on the megahertz scale but a properly updated GPU in the APU. Being minimally RDNA4 based (which there isn't one) or maybe even an UDNA one.
What I can see happening is something like a refined Pro HX 470 or maybe a Pro 385 on a current node in 2027/28 being offered in the same 5-30 watt power envelope of the current deck. With the growth/normalistaion of DLSS/FSR etc I can see them using frame gen to making 1080p the default option.
Also we have to see what UDNA brings to gaming performance and if they will utilise that?
They are also operating on a different price tier, a yesteryear design with deactivated cores, using c cores and disabled io, clocked low may suit Steam for there handheld. Steam desk will need to be more powerful, a quad channel laptop chip using old Treadripper io die will scare the competition.
The Strix Halo / Pro 385 APU is too large to be cost effective. Laptops/handhelds with this chip are $1200+.
Both of the above use RDNA 3.5. Next gen Medusa Halo Mini (2027-2028) uses RDNA 5, and supports LPDDR6 according to leaks.
RDNA 5 is more of a longer lasting product.
So AMD deems it feasible to create what are essentially "semi-custom" chips just for handhelds.
Did it open it up to the masses yes it did but it certainly didn't create the template
18 A /P is more performant/watt than AI Max 395 as I heard.
Is Framework investing in desktop with Panther Lake?
