Say AMD do provide significant value improvements with RDNA4 but don't see much uptick in sales/market share, do you think they stop that strategy and go back to mirroring nvidia's prices more closely (we tried and it didn't work so maximise $/card) or carry on for a few gens to see if they can get a foothold?

This post’s accuracy is not substantiated. Exercise discretion and wait for verified sources before accepting its claims.
they're not going back to anything, the strategy is to build a pile with hundreds of WGP and hopefully win it all!
(yes it's an exact copy of how CPU guys did it, but hey it works).
What was it 128megs for the 4k infinity cache ? I'm not sure that will be enough but we will have to see
For me to consider them i'd need 4080 performance at $600.

Yeah, but there are other caches besides MALL.
Slower but maybe (hopefully) for less.
they need to move units.
eh, might be too slow then compared to the competition. Certainly to slow for me. 4080 is the minimum i'd consider to replace my 3080 with. maybe it will last me another gen until rdna 5
that´s why I find hard to believe it will fit to ~240 mm2

I was thinking that too but looking into this, the fastest mass production GDDR6 is Samsung's 20gbps, SK Hynix and Micron are 18gbps. Samsung are sampling 24gbps and SK Hynix are (I assume) sampling 20gbps so it's not as bad as I first thought. Guess GDDR7 is around the corner so effort's put into that instead but would've been nice if 20gbps+ was more plausible for RDNA4

Plus side is more even arch/gen comparisons
The problem with GDDR7 for GPU designed with GDDR6 in mind would have a mismatch between bandwidth and compute, as well as memory support and compute size. Combined with a GPU that's going to be dropped in 18 months, and GDDR7 being more expensive per GB/s as it initially comes out, "eh forget it" sounds like a good strategy.

It's funny but not as eye popping as Zen5.
Mainstream parts will do just fine with G6.

it´s pitty that this cache didn´t make it´s way to the other Strix version. Still no mention about clock improvemnet (regarding to RDNA4)

Is RDNA4 going to show up in laptops next year? Intel is starting to put up a fight for the iGPU space, and I'm sure AMD would like to continue its dominance of the iGPU gaming market. "Battlemage" is showing what I'm assuming to be a 40% uplift (it says 56 EU vs the 128Eu benchmarks, but I'm guessing they're going for the doubled up floating point pipeline thing just like everyone else). Admittedly just in Sisoft so not a great benchmark, but RDNA4 plus a 16mb LLC would certainly be welcome.

No.
No they aren't.
That's very-very dead.
The next stop is Medusa, in 2026.

AMD wanted to do a major laptop push with both RDNA2 and RDNA3, and, well, crickets. Geforce is not just plain better in a limited power envelope, but also has a such massive brand power that laptop makers don't want to tie their expensive products to the brand that the market feels is inferior.
I think that outside APUs, laptop GPU penetration will significantly lag desktop GPU market penetration. Which is probably why Strix Halo, it lets AMD build a single product that's both the best CPU on the market and the best GPU AMD can put in the power budget.

RDNA2 did very well in laptops.
3, though. Oops!
Ouch. But happens.
Nah it's just that Apple proven big APUs are workable/viable in laptops and now certain OEMs get major stiffies for any IHV emulating them.
Also why LNL exists!
