Discussion Zen 7 speculation thread

Zen 7 uses 40% less power than zen 6 for the same performance

A14 itself is 25-30% less power iso perf so yeah

Vs N2?

Yuh.

Super Power Rail is their brand of backside power delivery?

Valve is waiting for something like Zen 7? Call me skeptical, but Valve has made it quite clear by now, both in action and interviews, that they're not interested in adopting the current gen architectures for their hardware because they want to pursue volume at low cost. If Valve is waiting for Zen 7, then that means we shouldn't expect a Steam Deck 2 until after the launch of Zen 8. Maybe they are, but does that mean we're potentially 5+ years away from a SteamDeck 2?

The CPU probably isn't what would be keeping Valve from launching steam deck 2. If anything, they would be waiting for AMD to move past RDNA 3.5.

There are no monolithic low power rdna 5 apus with zen 6 medusa

Zen 7 grimlock point 4 should come in at 15 watts or less

It's amazing how is sounds but Intel said the same with Panther Lake vs Lunar Lake node shrink gives 25-30% Power reduction ezy plus some architectural improvement and 40% is not a tall order.

Zen 7 would be too new for a 2028 launch from valve. a 4.0 ghz zen6c is already way ahead of 3.5 ghz zen2 that's in the steam deck, and probably uses the same amount of power. And now that Ryzen Z series is an actual line of products, amd can justify making a refresh of MDS1 with RDNA 5 instead of 3.5; there's no need for amd to wait until Zen7 to put a decent GPU architecture into their mainstream APUs

What is the need other way round? For a zen 6 refresh?

We are not even sure if medusa point has taped out now ???

They can just throttle Medusa Halo. That won't necessarily meet their cost metrics though.

Wasn't there a rumored custom RDNA5 SoC for the portable playstation?

Regardless, I think it would be stupid for valve to wait indefinitely until AMD finally releases an APU that fits their needs. Van Gogh is on N6, literally anything cheap enough on >=N3E/SF2 would provide the performance and efficiency they are aiming for.

No because Deck 2 is Qualcomm.

Writing was on the wall with Qualcomm doing the VR headset. Gives Qualcomm a shot now at other similar projects elsewhere and puts in incentive for others to work out better x86 to arm translation. Strategic mistake imo

as long as playstation is on x86 its fine. If sony ever moves to any other ISA its over for x86 then its time to worry but sony won't thanks to amd gpu ip

No?
Headsets just have very strict power ranges and no one ships a 5W SoC in x86 land.

It would be a pain and why would you migrate though when your current stuff works fine and in migration you will only suffer pain.
It maybe be possible for future Sony console to based on Rapidus

Headsets work on the same power envelopes as handhelds. So it's an avenue in. I'm not disputing that without something custom/semi custom that x86 (well AMD) can't provide that now, but allowing Qualcomm into the headset gives them an opening for the steam deck 2 and that gives them better tools to break into other markets.

Luckily for Qualcomm valve are not inept software wise, and it's their expertise backing Qualcomm that's should be AMDs concern.

Delulu.
The average PC handheld runs a 20W SoC.
Your Quest can dissipate maybe 8W.

They can. Just don't want to.

but allowing Qualcomm into the headset gives them an opening for the steam deck 2 and that gives them better tools to break into other markets.

What other markets.
PC handhelds are maybe 2m units a year and are detached from anything else. They're tablets and PC tablets are ~dead~.

Oh no my child s/w is the least of QC's problem in the PC space.

Do they have a roadmap past X2 Elite?

Haven’t seen leaks for X3 Elite
