Interesting!

Worth clarifying for the non-Swedophones(?) out there: according to this, Navi 20 ("big Navi") is supposed to be "pure" RDNA, and launch in early 2020. In other words, this is not a "half now, half next generation" situation as the title might make it seem. Still odd to make a hybrid like this, but I guess the architectures are modular enough to plug-and-play the relevant blocks on a driver level as well. This also clarifies the kinda-weird mismatch between RDNA being the architecture for "gaming in the next decade" while there being a "next-gen" arch on the roadmaps for 2020.

I wonder what implications this might have for performance and driver support. One might assume that these first cards will lose driver support earlier, but then again considering how prevalent GCN is I can't see that being for another 5 years or so anyway, by which time they'll be entirely obsolete. Performance enhancements and driver tuning might taper off more quickly, though, unless the relevant parts are RDNA and not GCN.

This is not surprising I think the "big Navi" was always getting the "Next-Gen" architecture it's just now they made RDNA as the "term" for the Gaming centric arrangement of the individual nucleotides (building block) that make "Next-Gen" architecture. Next-Gen is an all encompassing idea of such building blocks, and not one architecture that fits all. I see AMD/RTG splitting the Professional on a separate strand, that makes use of nucleotides that offer the best HPC, AI, or whatever the task requires. These nucleotides (bits and pieces) can also go down to the console market and APU's.

Remember AMD/RTG is setting itself up against a huge onslaught, and not just Nvidia or Enthusiast Gaming market which is just a pittance for profits. Compared that to what they might miss-out on if Intel makes strides into all these various emerging markets, while even later unlocks consoles and delivers their own true APU's. My hope is the Raja and all these other folks that were "brought-in" by Intel where compartmentalize, and didn't have full-understanding to the vision Lisa Sue (upper management) developed since mid 2016, but I think AMD has had such strategic overview compromised.

So, RDNA is compatible with the GCN ISA. I lost all hope of a proper OpenGL driver.

Yawwwwn .... based upon recent years, I have learned that until I see test results here on TPU and elsewhere, it's not real. These announcements and single game testing never live up to the hype.

We obviously need reviews, but there's little reason to suspect that AMD's engineering team can't come up with a more powerful and efficient architecture when aiming for a blank-slate design - it just takes time. This has been on the roadmaps for a few years already, so the arch is probably 4-5 years in the making, with efforts intensifying in the past couple. I just hope they've taken the necessary time to make it stick on the first try. Perhaps that was the reason for Navi being late? If so, I sure don't mind.

If true, this takes Rebrandeon to the next level: different architectures not only within the same product line, but within the same chip line.

 

[Casecutter]

Why is it we get one data point of say 90 (30 games x 3 resolutions) and we have all we need to see it as allegement of hyperbole.

Leaked info this close to a launch, usually depicts a best case scenario, that's why. It's not foolproof, but it's an educated guess

Pascal is the same thing with Maxwell then. Turing is Pascal with RTX on top of it then.

What?

 

[GoldenX]

What?

It's not a rebrand if you keep things from the old specs to keep compatibility. Also, G92 wants it's rebrand meme back.

So, no numbers on the 5700, it sounds like it will be another boring launch.

All 3 companies are rebrand masters.
AMD has the disaster of old GCN cards getting into new series, RX500 vs RX400, etc.
Nvidia has the G92 fiasco (9 cards?), the 100, 300 and 800 series, and 90% of their mobile chips.
Intel has 4 series of CPUs with exactly the same IGP, they only added an U to the start of the name.

VIA is the only good guy here.

This was about desktop GPUs, so that's what i was talking about.
AMD routinely does stuff like: https://en.wikipedia.org/wiki/AMD_Radeon_Rx_200_series#Chipset_table (i.e. everything from Terrascale to GCN 1.3, all under the 200 moniker).

The new ground they could be breaking is Navi chips actually being from different families if the above rumor is true: little Navi built with GCN blocks, big Navi without.

Some GCN blocks. That distinction can matter quite a lot depending on what blocks they are. Calling this a rebrand, though? That's idiocy. Even if it carries over some parts of the design, it's a brand-new die design with brand new core components. If that's a rebrand, there has really never been a new chip designed, ever.

They may be rebrands (man, did you dig up series I never knew existed on the desktop), but they still don't mix different architectures under the same moniker.

Come on people. Is my English that bad? This is about putting the same label on unrelated products, not about rebranding.

Low end 700 series are Fermi, low end 400 are Tesla, the 750Ti is Maxwell v1 in Kepler's lineup, G92 cards are in 4 different series (8000, 9000, 100, 200).
Nvidia has been having a good conduct lately, doesn't mean they are innocent.

So, bottom line, you're ok if little Navi turns out a Frankenstein monster and big Navi is the completely new architecture. I'm not.

The 750ti was little Frankenstein monster Maxwell and no one complained.
What maters is if the product is good, internally it could be an Intel IGP for all I care.

Do you even understand what that article was talking about? It said the little Navi could be built with Navi and GCN blocks and only the big Navi will be entirely new. The 750Ti was nothing like that.

In general, yes. But when you mix architectures like AMD does, you end up with missing features, depending on the model. Whether some codec isn't hardware accelerated on older parts or a new HDMI revision isn't supported, there's a lot of aspects where you can end up drawing the short straw.

Getting AMD cards is being a beta tester for them, look at the Vega 56, beating the 64 when undervolted AND overclocked.

Exactly what needs to happen for idiotic GCN news to stop?

GCN is an instruction set that is not getting dropped any time soon, definitely not sooner than nVidia drops its 11 years old CUDA.
As for "microarchitectures" AMDs' own Vega is quite different to Polaris.

So, RDNA is compatible with the GCN ISA. I lost all hope of a proper OpenGL driver.

And 2080 is compatible with 11 years old CUDA.
And, wait for it, Zen2 is compatible with 39 years old x86!!!

AMD just cannot innovate!

Beating 2070 when overclocked + overvolted:

What trickery is this? How dare they sell us slower cards for cheap?

Probably you informing yourself: https://en.wikipedia.org/wiki/Graphics_Core_Next

Graphics Core Next (GCN) is the codename for both a series of microarchitectures as well as for an instruction set

But I'm not holding my breath.

Navi also ticks to big technology check-boxes

Typo. Should be two not to.
