Actually decreased # of xtors.
A thousand cuts made whole.
They'll have to throw a properly long and annoying ISSCC presentation to explain all of it.
Not even twice.
That's reserved for N31.

I said better reason lol. Series X technical paper is convincing enough that whatever perf/w figure they are touting is purely on node improvement, not on the architecture level, and even that is meaningless without knowing what is being compared.

No.
No.
Ha.
what.
What node improvement?
N7+ over N7p is like 5% better power.
They're comparing fmax to fmax parts too, so you must understand that fmax went way up.
You didn't even see it.
Silence.
You just know.
Get you goddamed popcorn ready.

That is called a node improvement
Oh, I read it, both old RDNA and Series X hot chips presentation. and telling people to silence shows a lot about your character.

5% to 50%?
That's some 0 missing.
That 5% power in vacuum trasnalated to like 2% fmax and that's not the case.
At all.
Read them harder.
Yeah, gotta make sure no one says anything that could age badly.
I dropped some unkind words about AMD's chances in mobile and now have to be silent and watch.
Quietly.
Going from N7P to N7+ wouldn't bring the huge improvement that we see in the Series X GPU over RDNA GPUs. It has a 52CU GPU at a slightly higher sustained frequency than the 5700 XT's game clock, yet consumes significantly less power than a 5700.

Worse, XSX isn't even N7+.
EUV is deemed too voodoo for consoles.
Yes, this is the real shit.
That's how they plan to win gaming mobile with N22/23 and SmartShift.
True, I completely forgot about that.
Those look like they will be more than competitive against Ampere given recent events, I just wonder in how many laptops they'll make it. Cezanne+N23 will be a killer combo for sure.

A lot.
N22 too.
CZN is systems on shelf I think mid-late January'21; not much left to wait.
Plenty enough, it is just RDNA1+RT
And you don't get to decide that.
5700xt can be driven with lot less power without a big performance loss when undervolted. Plus, Enhanced N7 they are using on Series X is bringing 10% improvement on power on same frequency. I think this is the reason why Big Navi with RDNA2 is getting overhyped.

Bold.
Oh lord.
It's a console. It's inherently overvolted for yield salvaging.
Navi1x is already N7p bro.
The first shipping N7p part at that, ironically enough.
No there's no hype besides me shitlording here and on twatter.
AMD isn't even talking about Milan, Vermeer, Van Gogh, Cezanne and RDNA2 parts.
At all.
And those are literally 1-5 months away.
So are you saying Sienna Cichlid is N31 now? Or that Sienna Cichlid isn't RDNA at all?
Since we have Sienna Cichlid in Linux patches/drivers right now with HBM

No.
There's also patches for it with GDDR6.
Paranoid, survive, yadda, yadda, yadda.

They call it because everyone kinda adopted their die numbering scheme in usual conversations.
It's a 4die lineup with some extra bits.
What did it reveal about RDNA2's RBEs and rasterizer?
Also physical design?
Physical design optimisations of discrete GPU chips can be more aggressive, unlike monolithic APUs having to provision for the co-existence of high-frequency CPU blocks.
Also it is not like the architecture will look drastically different at the level of colourful white paper diagrams after just, eh, 1 year since the big revolutionary crop. Heck, these diagrams have barely changed structurally since Tahiti.

No one else here does. It brings nothing to the discussion.
