Official AMD Radeon RX 7000 Series (RDNA 3) Thread

[Nunz]

Why do you think that they would go for a smaller node specifically for a power consumption issue? While it is irregular for NV to go for an advanced node, I'm not sure that it's correlated to the power consumption. If the 4nm process was specifically modified for NV, it could just be learning from the mistakes of going Samsung 8nm for Ampere. Now that there's competition, NV isn't taking the chance of gunning for maximum profit margin. They made money hand-over-fist using Samsung instead of TSMC for Ampere.

I don't think the 4090 will have 12GB of vRAM, though, unless they bring back the TITAN name and relegate the 4090 to "4080TI early access".

If this 8gb is true for 7700 xt it will one of the most greedy launch i witnessed.

AMD made 7700xt as powerfull as a 6900xt and faster in RT and you put .... 8gb ram
I saw GN calling amd greedy with the new cpus like 5500 / 5600 and now they some sheningans with 7700 xt.


Seriously ? Is this a reason so the buyers of 6900 xt should not feel so bad ?
I even thought the 3070/3070ti getting only 8gb was kinda crappy.Now is AMD turn to do a bang with 8gb on a 2022 7700xt ...

AMD is going greedier and greedier.

At best a mid range card not an enthusiast card. It is what it is I guess

[pax]

I dont get that, it should be the 7600 not the 7700. The 7700 should be navi 32. It has the basic low 128 bit mem bus. 8 gigs in that case makes sense.

IMO its gonna be a 1080p card for new engines like Unreal 5.

[badsykes]

It is replacing the 6700xt series.This one has 12gb vram now.I hope it's a typo and as pax said it is about 7600 series.

[Sasquach]

Doesnt a more efficient memory subsystem, internal cache or faster internal cache memory and bus size make up for lack of capacity?

Maybe they're banking on improvements this way?
It should at least have the same amount of memory as the product its succeeding.

[demo]

Perhaps. I do remember a few generations ago (in the 1 or 2GB days?) they were able to somewhat make up for capacity with driver trickery of some sort. I believe 'delta colour compression' was the term and it had verifiable results.

But, unless there's some sort of significant technology like this, I wouldn't hold my breath. We'll know soon enough from the marketing.

[Mangler]

Maybe they plan on making the 79xx series the 68xx replacement as an homage to the 7950 and 7970?

AMD RDNA 3 GPUs rumored to feature up to seven chiplets

We already know that AMD is going to tap TSMC for the manufacturing of these new GPUs, but Greymon55 seems to believe the company will go with a mix of process nodes for the various chips involved. For instance, the Navi 31 GPU may be comprised of two 5nm Graphic Complex Dies (GCD), four 6nm Memory Complex Dies (MCD), and an interconnect controller die.

maybe or bigger infinity cache

Other rumors indicate that the flagship RDNA 3 GPU could sport a whopping 15,360 cores paired with 32 gigabytes of GDDR6

can you do 32gb with HBM ?


......
yes

Correct me if I'm wrong but HBM RAM is more expensive, no?

Yeah, I don't know, it used to be very expensive.

but then so is gddr6x and most likely gddr7

AMD confirms the arrival of RDNA 3 GPUs this year 2022

https://tutogame.com/en/amd-confirms-the-arrival-of-rdna-3-gpus-this-year-2022/

[Nagorak]

AMD is really doubling down on their chiplet tech. This may be the first time that the union of ATi and AMD actually results in a benefit on the GPU side.

[pax]

If some of the chiplets are sram cache on a package besides the gpu die would it still be L3/Infinity Cache or some kind of L4 cache? I cant see them put sram on the gpu die 3d stacked like the 5800x3d with the heat issues that gpus have now. I mean we are looking at 300-400+w on the gpu die.

It might explain if the 7000's still use plain gddr6. They simply amped all levels of cache as much as possible.

chiplets

two 200 to 250 watt chiplets will spread out the heat

i think it will be a large package like Threadripper maybe a little bigger

it may need hbm 3 just to get it on a normal sized card

[pax]

True its 2 gpu dies for the top end for sure. Everywhere says it also has gddr6 tho... I suppose it could have both. Maybe 1GB L4 hbm per gpu die.

All eyes are on September.

Probably a soft launch as the updated 6000s is due out next month. They updated 3 of the models the 6950, 6750 and 6650...

You'd need your own generating plant!

And some serious cooling too.

[Sasquach]

There is only one computer case that would fit and have everything required:

A Delorean.

-Whatever engine is in the car (swapped or stock) should produce enough power to feed both of the GPU's.
-Blast the A/C to keep it cool
-Utilize the GPU's to generate the 1.21 GW required.
-Travel back in time to anywhere you wish.
-Run minecraft in glorious 8K resolution with RT because that is what these newfangled graphics cards are meant to be used for.

Well that is disappointing if Nvidia can get the 4080 out in Sept. I probably wont be waiting to see how they stack up. Unless they are unavailable.

You're assuming mass availability though right?

Cuz they very well could release...10 and say "we released it in sept!"

AMD Begins Driver Enablement for Radeon RX 7000 'RDNA 3' GPUs

Well thats why I laughed at if available. I worked at it for the 3080, took me a month after release to secure. I do expect it to be worse this time though now that everybody has their bots all tuned up.

[Trunks0]

Erhm, you gotta remember what drove that problem last time though. Wasn't just miners and bots wanting all the cards. There where real global logistical issues and supply chain problems. We are not fully past that, but where are well past the point where everyone is aware and should have working methods to adapt.

That said, it's going to be interesting to see how it all plays out.

if they get POS mining in the miners should be out of our hair and that will stop a lot of card supply chain problems

i think prices will be high after AMD and NV has been seeing people paying 2x to 3x MSRP for cards for a year plus
and more people back to work and no more free government money

i don't think it will be harder this time than when the 2000's first started before bitcoin went nuts
a lot of those people that just paid 2x plus for a 3080 won''t upgrade this time for 999.99 to 1199.99 for a RTX 4080

What scares me is if sales of current gen crashes this summer they might cut next gen production down in anticipation of lower demand.

Im a buying next gen and maybe even gen after that in navi4 rtx5k. Especially if it goes 3nm. What Ive read is too impressive not to.

expected or they should any way

if you were going to buy a 6000 or 3000 you have by now

https://www.nowinstock.net/computers/videocards/amd/rx6800xt/

https://www.nowinstock.net/computers/videocards/nvidia/rtx3080ti/

as lots of cards out now

unless prices drop a good bit more most will wait on next gen at this point
or till the paper paper launches at least

i would buy this 3080 ti if it drops closer to 999

Pretty much everything is in stock and prices are dropping daily now... even seeing ads for some models now where they werent advertising for months. I just hope it doesnt spook the vendors because I think its gonna drop a lot more. Some like AMD might prefer to make more cpus instead.

i think AMD will go back to normal pricing or more normal anyway on the 7000's long before NV on the 4000's
i think AMD wants to get the GPU's more even with the CPU's in sales

on the aftermarket cards Asus will be last to go done in pricing
