No they're not, the naming scheme or (internal) chip jargons shouldn't be referenced in such a way!

Sorry, but how on earth does anyone see "Navi 2X" in friggin' quotes without any further data and think "Oh, that must mean 2x the performance"? Sorry, but that is a rather extreme leap of the imagination. Also, x as a multiplier is generally lower case, this is upper case, which is generally X as an unknown variable. 2X = 20, 21, 22, etc. is much more reasonable of an assumption than 2X = 2x performance.

2X is the generational code name for all consumer-oriented non-semi custom RDNA 2 silicon, with each piece of silicon then having a distinct second digit. End discussion.

Hopefully the cards launch in Q3 rather than Q4. Having new gaming products in time for CP2077 would be huge.

Oh in that case AMD should fire the wise guy who made that slide, I mean it makes little sense even now!
They shouldn't fire anyone, everyone's comprehension is appalling.

Fixed title, sorry for the confusion.

NVIDIA went a step further than Intel in supporting not just tier-1, but also tier-2. The complete sentence was:

"NVIDIA and Intel already implement VRS tier-1 standardized by Microsoft, and NVIDIA "Turing" goes a step further in supporting even VRS tier-2 ."
AMD also stayed that the VRS and Raytracing implementation were made in conjunction with microsoft, so it has to have the highest tier available

Maybe the delay in next-gen Navi GPUs is due to that. Will know for sure once they launch them.

I feel as though the confusion here was mostly caused because English isn't everyone's first language.

50% more performance per watt. So if a 200 Watt GPU gives you 80 FPS the next gen would give you 120 FPS? Or a more real thought would be 100 FPS.

Talk is cheap, I believe when I see it.

Vega's architecture was also supposed to bring 4X the performance per watt than previous generation.

But I hope this time it’s what AMD says.

Talk isn't particularly cheap when you're talking to investors and financial analysts. Fail to meet your promises and at best your stock tanks, at worst you get sued by shareholders for lying to them. Still, 50% sounds like a lot. Fingers crossed that it turns out that way - then we'll have a real fight on our hands in the next GPU generation, and prices ought to reflect that.

Considering that currently shipping Navi is "Navi 10" and "Navi 14", which can be summarized as "Navi 1x", I would assume that the next GPUs are "Navi 20" and "Navi 30", so the x stands for "any number", not "x-times improvement"
There we go....logic and intelligence prevail!! :)

Anyway, I can't wait to see these on the market and AMD catch up to performance per /W over the 12nm Turing parts. The put some special sauce in the 5600 XT which put it on par with Nvidia, so this should be interesting, as well as seeing an apples to apples comparison with Ampre and its increase in efficiency p /w along with the shrink to 7nm...I bet NV still holds that lead........

"special sauce"? If by special sauce you mean they freaked out and pushed out a firmware right at launch that blew initial thermal and power targets, then, yeah, "Special".

I feel it's disappointing to see that there are no major new architecture in sight; just more iterations of Navi.

If they'll actually deliver the only thing that will prevent me from buying this would be the driver issues that we saw with almost every launch from team red's GPU camp.
It has been a recurring subject with every release, since the underlying driver problems remains unfixed.

Talk is cheap, I believe when I see it.

Vega's architecture was also supposed to bring 4X the performance per watt than previous generation.
And Polaris promised 2.5x performance per watt, while it turned out that they meant if it ran at 850 MHz vs. an older GCN at a higher clock…
AMD's GPU department have a long standing tradition of over-promising and under-delivering, unfortunately.

I am not sure about that Polaris is faster than Vega and the clocks for Vega are 1630 MHz.

Forgive I should have said Tahiti at 1100 Mhz but Tahiti was no joke.

Are you on hallucinogenics ? Vega was never supposed to bring 4X the performance per watt, I swear you're all gonna scour the depths of the internet just to find that one fake leak to make your point.

It was more like that they wanted to easily defeat the 1660 Super and 1660 Ti, but because it was priced so close to the RTX 2060 non-Super, they decided to increase the clocks to make it competitive with it. They just changed targets at that price range, and it was a good idea.

I am not sure about that Polaris is faster than Vega and the clocks for Vega are 1630 MHz.
You're getting mixed up there dude. Polaris and Vega are GCN (4th and 5th gen) architectures.

Yeah I was too quick with the trigger I should have said Vega vs Navi which really impressed me with the fact that the 5700XT is faster than the Vega 64 with 1/2 the ROPs.

Looks like Nvidia guys cant tell apart which are fake and which are official AMD slide. And the fake slide is spread by WCCFTECH.o_O

Dont worry someone will take this video as official AMD video also.(Dont click)

While it is technically impressive, please note that RDNA is quite different to GCN at SIMD-level, where RDNA works with SIMD32 (native Wave32!!) and single-cycle instructions.

GCN (5th gen) used SIMD16, which means it issues instructions every 4(??) cycles, where as RDNA issues it every cycle. This inherently makes a 40 CU (RX 5700 XT) cluster faster than the previous 64 CU cards (Vega 64/Radeon VII).

Depending on what you're trying to achieve (raw core performance vs. optimized IPC), GCN5 can still compete well against its younger sibling. However RDNA can do everything GCN5 can do, except beating it in raw compute loads.
