Leaked AMD Gainsborough chip points to a Steam Deck 2 mostly through a name AMD picked
Leaked AMD drivers and shipping records show a semi-custom 'Gainsborough' chip on TSMC N3P, with test hardware already shipped for validation. Its tie to a Steam Deck 2 rests mostly on a Final Fantasy codename, so buyers deciding whether to wait for Valve have little more than a name and a shipping record.

What happened
- Leaker Gotou_3rd says AMD's next Ryzen Z3 handheld chips share Gainsborough's 25mm by 25mm package size and target 15 watts, the Steam Deck's power envelope.
- As of last month, according to The Verge, Valve was still working out 'how and when' to make a Steam Deck 2.
- Moore's Law is Dead says the signs point to Valve as the customer and expects a new handheld in late 2027 or early 2028.
- Gizmodo reports that core counts and clock speeds have not leaked, and the only architecture hint is AMD's rumored Zen 6.

Why it matters
- decision An owner of an aging Steam Deck has to choose between a handheld on sale today and a sequel whose chip and ship date Valve has not confirmed.
- contradiction Gizmodo and The Verge read the codename in opposite ways, and that reading decides whether the validation shipment counts as Valve news or only as AMD news.
- constraint A test-equipment shipment can only show that some customer is evaluating Gainsborough, and semi-custom history means the device that ships could belong to someone else.
- constraint If Gainsborough sits in the Ryzen Z3's 15-watt class, any generational leap would have to come from N3P and the new architecture within the original Deck's power budget.
The person this leak is for owns a Steam Deck that is four and a half years old [1]. Valve has told that person more than once that a sequel waits on a chip with a "generational leap" in performance and efficiency [1]. Gainsborough gives them a codename to weigh against the handhelds already on sale [2].
The documents themselves are narrow. AMD's latest drivers name the chip [2]. IT Home found import/export records of AMD shipping test equipment for it, and took that as a sign that a potential customer may already be testing the part [4]. Semi-custom means it was designed for one specific customer [3]. Neither the drivers nor the records name that customer [2][4].
The case for Valve rests on a name. Aerith, the first Deck chip's codename, is a Final Fantasy VII character whose surname is Gainsborough [7]. Gizmodo wrote that this "seems like a pretty strong hint" [19]. But Valve designers told The Verge that AMD picks those names, and that Valve didn't really want them [8]. AMD also sells the family to other companies: the Ryzen Z2 A that Microsoft and Asus put in the $500 Xbox Ally is an "Aerith Plus" chip [9].
The package size is a harder fact. Import records list Gainsborough at 25mm by 25mm [5], and the original Aerith reportedly measured 19mm by 19mm [10]. That is about 1.7 times the footprint, 625 square millimeters against 361 [1]. The Verge called that large for a Steam Deck. It allowed that the chip could still be efficient, and cheaper, if it stays close to AMD's own 25mm Ryzen Z3 [23].
Semi-custom parts also change hands. The original Deck chip was long rumored to have been designed for a Magic Leap headset and offered to tablet makers before Valve took it, and parts of it went unused [11]. The Verge's reporter wrote, "I'm a tad skeptical" [22].
I'd split the decision into two questions. The first is whether the handheld you own still runs your library at settings you accept. The second is whether you need a new device before late 2027, which is the earliest window Moore's Law is Dead has suggested [13]. Gizmodo calls the leaker mostly reliable [21]. If your current Deck holds up, the leak changes nothing on either side of that date. If it struggles and you need something soon, buy a handheld that ships today, because Gainsborough is still a forecast. Only the owner whose Deck struggles and who can wait past 2027 has a reason to hold out for this chip.
That owner should budget without the old anchor. Gizmodo wrote that nobody, Valve included, can estimate what a Steam Deck 2 will cost [20]. It also wrote that RAM prices ended any chance of the Steam Machine or Steam Frame costing less than $1,000 [16]. Valve software developer Pierre-Loup Griffais told IGN that the RAM crisis had not changed Valve's Steam Deck 2 plans, according to Gizmodo [17]. The original Steam Deck cost $400 [18].
What to watch
- Launch specs for AMD's Ryzen Z3 and Z3 Extreme, the closest public proxy for what a 25mm, 15-watt AMD handheld chip delivers.
- Valve naming a chip partner or a Steam Deck 2 window, which would replace Moore's Law is Dead's late-2027 estimate with a company date.
- New import/export records showing Gainsborough shipments in production volume, beyond the validation test equipment found so far.
