N1X isn’t a threat IMO, it comes with stock ARM cores from 2024.
It has the green badge and actually useful GPU IP, plus Mediatek is doing the SoC engineering as NV is not good at that.
I'm sure they are having fun writing AArch64 gaming drivers.
Glymur at the least CPU side is going to very good but it won’t come out till H12026. Medusa will likely launch mid by 2026.
Medusa (mobile) is CES'27, desktop and server is H2'26
And yes they are the ones with the good CPU IP.

Nothing like a loss of market share or revenue to move these companies. If QC/NV can manage to win share in PC there will be some innovation.
100M USD marketing funds is pocket change for Jensen if it means adoption of their arm platform like how it was for CUDA.
NV can incentivize lots of existing SW vendors to start optimizing for their ARM platform first. As it is, lots of SW vendors already have relationship with NV, Jensen might just make it specific to his SoCs and not for QC

They do not care about Intel.
Why not? Intel currently holds the #1 position in x86. Seems like an AWFUL lofty claim. Please explain.
Venice-D CCD is, for, well, Venice-D.
They're not doing dense spam on DT.
Venice D is just a bunch of CCD's using Zen 6c cores. What makes you think that it wouldn't make sense for AMD to put one of them on the desktop along side a full Zen 6 (12c) and the new IOD? I figure AMD will NEED this to compete with Nova Lake's 54 core variant since there is no possible way a 24c Zen 6 is going to compete in MT against a 54 core Nova Lake. Do the math.

I guess AMD could simply concede the MT performance crown that they have been touting for years now to Intel and become the single thread king? Kinda a wierd role reversal don't you think?

Besides, I think it way more likely that AMD will continue to improve the IOD capabilities through trickle down from server learnings. I expect more of this cross-pollenation, not less.
Dense CCDs will never be in client, only cheap mono parts.
Ironically the Venice-D CCD is the priciest CCD ever.
Why not? What practical reason would AMD have NOT to do this?
Enough big boy cores is enough, want more than 48 threads, you need more memory channels.
Just buy Threadripper.
Except it is not likely that a Threadripper system can compete in price with a Nova Lake system. Not even close. How would the economics of that work?

It is interesting to me how many people feel that the design OEM's are simply lazy and/or stupid. Ever meet any of these guys? The reason innovation is slowing down is because foundry technology advances are slowing down. MOST of the big performance improvements have come by taking advantage of vastly larger transistor budgets gen over gen. That is no longer the case.

There are still tricks being put together though. AMD's early adoption of chiplet tech has paid HUGE dividends for them. Packaging technology is increasing rapidly side by side with chiplet design now.

There is some hope for new transistor cache densities around 2030-2035, but other than that, what large process improvements (ie 30-50% density increases of the past) are there? To make things worse, every one of the new generational improvements comes at an exponentially larger cost and is giving incrementally smaller improvements.

FYI, nVidia's genius is NOT in their chip design (which I believe they simply use brute force methods that are very expensive to get the best performance possible at all costs), but rather in their software support library and services IMO.

Because.

well the world extends beyond the walls of x86.

no it's a product with a designated CCD (well, stack, really).
What makes you think that it wouldn't make sense for AMD to put one of them on the desktop along side a full Zen 6 (12c) and the new IOD?
Because client doesn't need any of that.

No they don't.

The world is more than just cinememe.

who cares.

Completely divergent roadmaps.

Here is the thing most DIY sales are for gaming. So in that in mind, the "52" core NVL part has to outperform the 10800X3D and the 10950X3D in gaming.

Its also likely going to very expensive. So 99.99% of gamers will go for Zen6 X3D. What the NVL part will excel at is Cinebench but excelling in those don't move units otherwise Arrow lake would be selling like crazy.
----

The core of client business is laptops and here Intel just doesn't have a good product in 2026. What is Intel's response to AMD/QC/NV in the laptop space in late 2026? Its currenly a 8+4+4 NVL-H part.



They need to focus on this and not creating 52 core CPUs that will most likely get bottlenecked by mem bandwidth.

Yes, the older Genoa (by that time) will be affordable, with up to 96 cores and 12 channel memory and avx-512. Turin may or not be affordable, but it has full width avx-512, and a year or two from now, who knows.

Venice CCD being very expensive, presumable volume and margin of such a hybrid would be too low (~5000 buyers at $2K price would still be only 10 mil rev, probably not even enough to cover the engineering cost).

Plus, they already tried it with the original Threadripper; demand eventually petered out from the gaming side, while it cannibalized server parts on the workstation side, which is why they ended up making Threadripper a stripped-down version of their server platform and reduced the price/perf advantage over Epyc.

tl;dr: They won't waste money just to make a small group of desktop enthusiasts' wet dreams come true.

Remember, AMD needed *something* to show in the slides - and in case of Zen 1, Zen 1+, and Zen 2 it really couldn't be their single-thread performance. So in case of Zen 1/1+ they were fine with the server-derived 8c choice. With Zen 2 they needed something more, hence the easy-enough 2 CCD config.

Starting with Zen 3, they have been competitive in single-thread. So it was pointless to chase MT just to show something in slides. Keeping the 2 CCD config was easy enough to reuse in newer gens.

Dense version trades max clocks for density, so having 4-ish ghz peak is hardly going to be attractive on desktop

Links to some data please. I don't think this is correct.

No, they wont. This would be about maintaining dominance over Intel's Nova Lake offerings.

See below (as this is nearly word for word how I was about to reply).
Who cares if you get 32 cores at 4 ghz instead of 12 at 5.x ghz? Its roughly double the wrought Mt performance. Your primacy CCD should still be a 12c for peak st and lightly threaded loads.
I saw another rumor yesterday that suggested a dual CCD with 12 full Zen 6 and another with 16 Zen 6c. I don't see the point in this configuration since the 16 core CCD would be unique to that usage while the 32 core CCD would be shared by EPYC D Zen 6.... and it would also bring the performance of AMD's Zen 6 offering in MT up to snuff with the rumored Nova Lake.

So, from the top of my post here, I am saying that desktop processors are being replaced by laptops in MOST applications. The applications that are left are:

1) Gaming (likely <10% of desktop users)
2) Workstations for editing video/graphics (my guess is a big percentage of the remaining 90%)

Seems to me like MT is way more important than ST for desktop. Someone steer me straight if I am off base here.
