Official AMD Radeon RX 7000 Series (RDNA 3) Thread

Not sure I see that they all have 2 GCD's but there are 2 XTX variants according to one leaker listed under rogame. Latest rumor is that theres more IF cache in one model.

well "Three possible AMD RDNA 3 "Navi 3X" GPU board IDs"

Navi 3X is listed a 2 GCD's

very well could all be the same base Navi 3X card and higher clocks and or water cooling or a forth power plug

[pax]

The GCD is said to be 308 mm2 on 5nm vs the 520 mm2 on 7 nm that navi21 had but it only contains the shaders and RT cores... no IF cache as they are on the MCD's and info is pretty solid on it being 12k shaders per gcd. 533 mm2 total with MCD's.

GCD is small enough that they could fit 2 on the package tho for sure.

I think what makes a dual gcd board likely is that its a bit hard to see them make 3 7900's from a single gcd. That would be like 2 cut down dies and at some point it gets close to the full Navi32 die or the perf in between cut down navi 31 dies is minimal. With navi 33 being close to the perf and shader count of the 6900xt there wouldnt be room for more than one navi 32...

Would be great to see Su show the 7900xt package with a slot for a second gcd like she did for ryzen way back when before dual cd's were a thing.

Also having more IF cache on the top sku makes more sense if you're having issues feeding 2 GCD's on the 384 bit bus.

List under one GCD only would be:

12k shader xtx

10k shader xt

??? shader le?

8k shader navi 32

~4k-5k shader navi 33.


Makes way more sense to see 16 k dual gcd xtx so

16k dual gcd xtx (potential for more later like 20k or even 24k?)

12k xt

10k le

then navi 32 has maybe 2 skus

8k full xt

6k cut down

navi 33 tween 4-5k

That last being cut down to low end. Its hard to see navi 33 having more shaders than navi 21. So my bet is its ~4k shaders max

I can imagine there would be 4 8 pin plugs on the dual gcd one and tho it would likely run lower clocks it would still leap ahead at 24 k at 2.5 ghz vs the 3 ghz 12k shader model.

It wouldnt bother me in the least to see 4 8 pin plugs. Id just worry about overall wattage. Probably 600w easy so watercooling for sure.

Recently saw a post that showed nvidia had an air cooler even bigger than ref... cant find that link right now tho

oops found it: https://videocardz.com/newz/massive-...-been-pictured





Speced for 900w damn... maybe amd is reaching for the same kind of thing. I mean why just go for value that everyone is hoping for when you can go for both lower cost mid range to high cost trophy winner.

AMD Radeon RX 7000 (RDNA3) GPUs Will Be Vulkan 1.3 Conformant

All three major GPU manufacturers now support the new standard.

The Vulkan 1.3 specification released in January this year is now widely supported by AMD, NVIDIA, and Intel GPUs. The recently launched GeForce RTX 4090 GPU supports the newest 1.3.3.1 implementation, and it appears that Radeon RX 7000 desktop GPU will have similar support as well.

A brief look at the conformance list shows that almost all modern graphics, including NVIDIA GeForce RTX 30/40 and Intel Arc A-series, now support the latest 1.3 standard. AMD has recently confirmed that ‘undisclosed products’ based on RDNA3 GPU family has successfully completed Vulkan 1.3.3.1 conformity test suite. Support for this graphics API is confirmed for Ubuntu and Windows 10.

Mighty fine of them to validate them vulkans. I do be wondering how long Microsoft and Khronos are gonna last before we start needing new gpus to take advantage of a major DX/Vulkan version bump

Hopefully gone are the days where that is needed

more likely they would just run both cores in their efficiency sweet spot which would let them run off 3 plugs just fine i'd imagine. don't need the clock of all clocks if you are throwing all the cores at it.

for thr stock cards

Asus, MSI and Sapphire .... would OC and need 4 plugs most likely and better cooling

but they got all those 4090 coolers the size of aircraft carriers and it oc is so locked up it doesn't need them

I remember the old days when major Direct3D updates were frequent. They had to lay a lot of groundwork for the games of today.

AMD Radeon RX 7900 “RDNA 3” Engineering Sample Pictured, Massive Triple-Fan Cooler With Just Two 8-Pin Connectors

[pax]

Looks like its not 3 high end models after but 2... keeping the uber for later like nvidia its 4090ti I imagine.

[Nascar24]

Yep, looks like 7800XT and 7900XT with the XTX in qtr 1.

[SSXeon]

Yep, looks like 7800XT and 7900XT with the XTX in qtr 1.

Rumor now is:


Navi 31: 7900XTX (350w) & 7900XT (300w) = Q4-22

Navi 32: 7800XTX (w?) & 7800XT (w?) = Q2-23

Navi 33: 7700XTX (w?) 7700XT (w?) 7700LE (w?) = Q1-23



3D Infinity Cache might come as the 7950 refresh, don't think they will add it for Navi 32, only clocks/mem speed.

[pax]

Jim at Adored gives a good analysis before the announcement:

[yt]yAfwhR6Bfr4[/yt]

He estimates the 7900's dies cost about 30% less than nvidia's 4090 but he doesnt think that will have anything to do with perf/price.

The chiplet strategy can give the next amd chip 50k shaders on 3nm vs max 30k on nvidia. Nvidia simply needs too much of the gpu die for L2. And he says theres no evidence nvidia has any chiplets based gpu in the works yet... that it takes years to get this kind of tech off the ground.

Nvidia about to be intel'd? With the next 4-5 years where amd has the upper hand...

Nice! Haven't listened to AdoredTV in a minute!



Yes it costs less! Its A LOT smaller and is on 5nm, not 4nm. As for price performance, no one knows real price until Lisa or Jacket says it. 2 more days!! I just hope real gamers and enthusiasts can get one if its good! This scalping with the 4090 is MADNESS!!!!!!!!!!!!!!

Ya hadnt seen a vid by him in a while. Im a bit surprised he says theres no chiplet based gpu in the works by Nvidia AFAHK. Isnt Hopper chiplet based?

[Nascar24]

Well Billy, It's the XTX for you or you wait another year for your 7950XTX.

No, hopper is not Multi Die. Jensen supposedly said why would they when they make amazing monolithic designs. Honestly he is not wrong. Maybe blackwell could do some sort of chiplet, but for gaming its still hard for multi GPU dies to work well in games it seems. The multi (2x Navi 32) that was rumored, is most likely a Pro workstation version.

Well Billy, It's the XTX for you or you wait another year for your 7950XTX.

Honestly, if it is 350w and very strong, I might be going back to team red. O yeah and IF I CAN GET A DAMN CARD!!!!!!!!!

[bill dennison]

Well Billy, It's the XTX for you or you wait another year for your 7950XTX.

7950XTX was always Q1 23

another year form now we will be looking at the 8900 XTX

with Multi Die she can and i think she will put the GPU's on the same 1 year train as Ryzen (barring another pandemic)

and do the same to NV as Intel as she can make new Multi Die faster than they can with monolithic

[SSXeon]

7950XTX was always Q1 23

Well never "always". Q1-Q2 seems likely. We shall see.

it depends where the 7900 xtx is to the 4090 how fast they bring it out i think

Alright guys, Jim at AdoredTV explains what's gonna happen!

TL/DW: Chiplets for the multi generational win!

[SSXeon]

If 7900XTX is 350w TBP, its a game changer.

But can we get one???? Preorders, bot detection, one per gamer?

We still have scalpers with 4090s, this might be the same sadly.

You’re dreaming Billy, 7950 is going to be the refresh in a year. Unless that’s what they call the 7900XTX instead. Until I see something otherwise we are on a 2 year cycle.

I find that little video silly, he acts like NV is not working on a multi chip down the line and already have.

well they are in second place at best with MCM
AMD has a ton of MCM patents by now with Ryzen and now RDNA 3


they are top dog with monolithic but MCM not so much

Sounds like they can use simds shaders to do just about anything using a software emulation to avoid any kind of bottlenecks. Unused shaders that can be repurposed to run any other function of the gpu.

Die shot that kind of reveals they are going with one GCD only. Looks like the 7950xtxxx refresh will be just more speed faster ram and more Infinity Cache.

Unless they make a new package...
