All die sizes are within 5mm^2. The poster here has been right on some things in the past afaik, and to his credit was the first to saying 505mm^2 for Navi21, which other people have backed up. Even still though, take the following with a pich of salt.

Navi21 - 505mm^2

Navi22 - 340mm^2

Navi23 - 240mm^2

Yeah, all gamepass.
Really bad revenue, catastrophic flots monetarily.
Ah, you don't use it yourself, so it must be niche ... that's a way to see it.
Local LLMs are just niche.

Hmm, so I really should have sold off my 6700xt and used that cash to buy a 9060xt 16gb a few months ago. I thought dropping hawaii chip support in 2020 or so was annoying but sort of understandable. This makes little sense to me given how many 6000 series cards are out there.

Yeah AMD's management of their APU product stack is very confusing. I don't understand their refusal to have the latest GPU IP on its latest APUs. And also their refusal to launch cheaper NEW APUs instead of just rebranding old ones.

Like do they really not have cash to ensure that 2025 APUs have RDNA4 iGPUs? How does Intel manage to have their latest CPUs use the latest Xe when theyre a lot more strapped on cash?

Ryzen 5000H mainline series released in mid 2021 was still using Vega. And Barcelo R rebrand in 2023 still having Vega. New base Ally still using RDNA2. Krackan Point launch this year with RDNA3.5. Hawk Point refresh this year using RDNA3.

Why is it so hard to just synch up CPU and GPU IP, release at the same time, and ensure the entire product stack moves forward at the same time instead of releasing rebrands to satisfy the low end, while simultaneously dropping driver support for those rebrands?

Now yes, I get that this behavior doesnt actually affect sales much and thats why they do it to save money. But its still annoying and anti-consumer.

From what we've seen. AMD doesn't target node flexibility for their graphics silicon IP. If they design RDNA2 on N6, it can only be produced on an N6 node. They designed RDNA3 for N5, 3.5 on N4P. You rarely see them port graphics IP across nodes these days. When they "refresh" an older product, all they typically do is just rename an existing product and tweak the bin dividing lines for yield.

Continuing with the rant on the theme of AMD mismanagement of mobile products....its very sus that theres no RDNA4 mobile dGPUs when RDNA1, 2 and 3 all had mobile SKUs. Sure they sold poorly but AMD still decided to release them. But now that they FINALLY have a good arch, all of a sudden they decide not to release mobile dGPUs? This is either extreme incompetence from AMD or some kind of industry wide manipulation to prevent competition.

I see that you changed the goalposts from:

And oh, no one heard about Indy.

to:
Really bad revenue, catastrophic flots monetarily.



I'll take that as a retraction.
Regardless, that's over 5 million people playing AAA Vulkan games in their PCs in 2025 just from recent IdSoftware titles. This is without counting that little game a couple people heard of called Baldur's Gate 3 and probably has over 200k unique users playing it on Steam.
And then there's the game Valve will use to push Deckard, which could be Half Life 3.

Meaning Vulkan is still widely used and isn't going away anytime soon. Taking away its support is a terrible idea.

And here I thought AMD was becoming a software company

AMD is Becoming a Software Company. Here's the Plan

Just a few weeks ago, AMD invited us to Barcelona as part of a roundtable, to share their vision for the future of the company, and to get our feedback. On site, were prominent AMD leadership, including Phil Guido, Executive Vice President & Chief Commercial Officer and Jack Huynh, Senior VP &...

I was pondering whether to keep my RX 6900XT with a new eGPU case to use with my Legion Go or sell it.



AMD decided for me that I just need to get rid of this GPU ASAP, after them screwing up its resale value.

And now I might never go back to AMD desktop GPUs ever again, after 20 years of using those almost exclusively.

Bravo, AMD.

AMD backtracks after blowback

https://www.tomshardware.com/pc-com...d-handhelds-will-still-work-with-future-games


AMD clarifies that RDNA 1 and 2 will still get day zero game support and driver updates — discrete GPUs and handhelds will still work with future games​

News
By Andrew E. Freedman published 48 minutes ago
"Maintenance mode" might be a bit more than just maintenance, AMD tells Tom's Hardware.

Following AMD's decision to put RDNA 1 and 2-based GPUs into "maintenance mode" in order to focus on new features for its more recent graphics technology, the company is backtracking a bit. AMD tells Tom's Hardware that RDNA 1 and 2 won't be left in the dust entirely when it comes to game optimizations.

"New features, bug fixes and game optimizations will continue to be delivered as required by market needs in the maintenance mode branch," an AMD spokesperson told Tom's Hardware.

That's a statement that's likely to confuse some customers, as it's unclear what those "market needs" are. This sounds like new features will still be focused on RDNA 3 and 4-based GPUs, but AMD's clarification implies that RDNA 1 and 2 will continue to get day-zero support for games, including on handhelds.

This is meant to clarify a statement from yesterday that read: "In order to focus on optimizing and delivering new and improved technologies for the latest GPUs, AMD Software Adrenalin Edition 25.10.2 places Radeon RX 5000 series and RX 6000 series graphics cards (RDNA 1 and RDNA 2) in maintenance mode. RDNA 1 and RDNA2 graphics cards will continue to receive driver updates for critical security and bug fixes."

That statement, which would apply to a number of fairly recent graphics cards, as well as the integrated graphics in some laptops (like the Ryzen 7000 and 6000 series) and the Asus ROG Xbox Ally handheld (but not the more expensive Xbox Ally X), caused serious blowback among PC gamers and in the enthusiast press.

Tim at Hardware Unboxed had a 15 rant about it yesterday. Same with Daniel Owen. Hopefully this is a real walkback and not PR spin after the fallout. I'm definately leaning towards just going with a 5060ti 16gb if I buy a new card this year.

They may not really be backtracking... since they never said that games wouldn't work. Only that it wouldn't get optimizations.
And now they're saying game optimizations are coming to RDNA1 and 2.


Honestly, I think most people would be understanding for not optimizing for RDNA1. There's like 3 dGPUs with that arch that stopped selling in 2020/2021, and zero iGPUs.

It's stopping RDNA2 optimizations that was really bad.

Well, looks like it has been slightly retracted / corrected :
