AMD RDNA2 Graphics Architecture Detailed, Offers +50% Perf-per-Watt over RDNA

With its 7 nm RDNA architecture that debuted in July 2019, AMD achieved a nearly 50% gain in performance/Watt over the previous "Vega" architecture. At its 2020 Financial Analyst Day event, AMD made a big disclosure: that its upcoming RDNA2 architecture will offer a similar 50% performance/Watt jump over RDNA. The new RDNA2 graphics architecture is expected to leverage 7 nm+ (7 nm EUV), which offers up to 18% transistor-density increase over 7 nm DUV, among other process-level improvements. AMD could tap into this to increase price-performance by serving up more compute units at existing price-points, running at higher clock speeds.

AMD has two key design goals with RDNA2 that helps it close the feature-set gap with NVIDIA: real-time ray-tracing, and variable-rate shading, both of which have been standardized by Microsoft under DirectX 12 DXR and VRS APIs. AMD announced that RDNA2 will feature dedicated ray-tracing hardware on die. On the software side, the hardware will leverage industry-standard DXR 1.1 API. The company is supplying RDNA2 to next-generation game console manufacturers such as Sony and Microsoft, so it's highly likely that AMD's approach to standardized ray-tracing will have more takers than NVIDIA's RTX ecosystem that tops up DXR feature-sets with its own RTX feature-set.

Variable-rate shading is another key feature that has been missing on AMD GPUs. The feature allows a graphics application to apply different rates of shading detail to different areas of the 3D scene being rendered, to conserve system resources. 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 didn't detail its VRS tier support.

AMD hopes to deploy RDNA2 on everything from desktop discrete client graphics, to professional graphics for creators, to mobile (notebook/tablet) graphics, and lastly cloud graphics (for cloud-based gaming platforms such as Stadia). Its biggest takers, however, will be the next-generation Xbox and PlayStation game consoles, who will also shepherd game developers toward standardized ray-tracing and VRS implementations.

AMD also briefly touched upon the next-generation RDNA3 graphics architecture without revealing any features. All we know about RDNA3 for now, is that it will leverage a process node more advanced than 7 nm (likely 6 nm or 5 nm, AMD won't say); and that it will come out some time between 2021 and 2022. RDNA2 will extensively power AMD client graphics products over the next 5-6 calendar quarters, at least.

Master TomIn Germany it so hot in summer, that you need air condition anyway. In winter the i9-9900K and the Radeon Vega 64 Lquid Cooling help heating the room :)
In which country do you live?
That is with Air Conditioning.
ARFRTX 2080 Ti is a 300-watt part. So, you expect 33% higher performance, not double the performance up to 400-watt.
That would have been relevant when the 2080ti launched but not years later. Linear progression is not impressive. Too me anyway.

I would rather compare all the aspects of a graphics card. Power draw, performance, price maybe even value. The 400W is a lot for a GPU. Although if it turns out it is a monster and performs extraordinary, then why not get it. I'm sure the performance/price ratio will not be great anyway.

It's a 260W part in FE (and many card partner) form(s).

lynx29im ok with 400w as long it beats a 2080 ti by 15-20% and costs around $799
If 505mm2 RDNA2 chip doesn't beat 2080Ti by 15%, I'll apologize to Raja Koduri.
moproblems99expected performance of Ampere...but.....at significantly more power usage.
There is no levels to mind blowing fanboi insanity you guys cannot dive into, is there?
You are in a thread about 350W cards.

I judge your posts by their content, whatever you own, be it ryzen or Empire State Building, doesn't change it.

You are posting in a thread discussing 350W card, come into 400W card that is allegedly faster, then claim 400 is "substantially higher power consumption" than, oh wait, 350W.

I hope it will be even a little bit faster.

It has to be more than "a little bit" more than 15%.
This is the first GPU from AMD that supports DX12U, so should be having more significant performance optimisations.

Has anyone got information what's going on with Big Navi 2 ? Performance and launch windows estimates?

I just hope it's not the Xbox SX announcement. I mean he is from AMD right? If it was a Xbox announcement, that would come from Microsoft not AMD.

Reason I mention this is due to a Reddit thread about it.

I've never seen AMD so quiet about a CPU architecture and a GPU architecture in a very long time. Last time they were this hushed about something was back when the Athlon 64 was released. And for ATI, when the Radeon 9700 Pro.
When many months before Fury & Vega's launch, AMD was pretty vocal about them. We all know how that turned out. They were great, but not great enough per say.
This RDNA2 is a interesting and might very well propel AMD into full stack competition, evening out the GPU playing field against Nvidia. If this happens, PC Gamers are going to greatly benefit this Fall, Christmas & into 2021. :) I hope I am right :D

Yes, I hope Zen3 will surpass Intel and Big Navi the RTX 3070.

Surpass the RTX 3070? Umm Big Navi is suppose to be AMDs highest end GPU, that's quite belittling it don't ya think? Lol

Given AMD recent history its hard to gauge what their card will actually compete with. I think everyone knows they can make a 350W big ass die card to compete with the 3080/90 if they wanted to my issues is believing they would do that over making 3-4 16 core ryzen 4000 chips they can sell for $700+ each with the same amount of silicon.

Difference here is that RDNA2 is a new design. AMD hasn't had a new GPU design in a long time. We will have to wait and see what comes out.
The mainstream market is where the majority of profits & sales come from.

And that's exactly why AMD hasn't bothered competing at the top end for the last few years. A lot of people tend to expect AMD to always be the cheaper brand, even if they tend to lead in performance, efficiency or really just about anything else. Nvidia can still command a premium by selling equivalent performing cards just because they're Nvidia, this is the same even for Intel though with locked chips they tend to segment the hell out of that market covering pretty much every price point imaginable.

The point being buyers tend to expect more, a lot more for a lot less ($) from AMD than their bigger brand counterparts. This is why selling a near 3080 performant chip, at similar prices is gonna be hard for them.
