AMD Navi 23 ‘NVIDIA Killer’ GPU Rumored to Support Hardware Ray Tracing, Coming Next Year

[timorous]

Making excuses for what is a lie.

Are you now claiming that games on PC will now be optimised on a per GPU basis like consoles?

1) Speculation and estimation are not lies so stop being dramatic.

2) That is what the AMD / NV driver teams do in the PC space. In the console space devs optimise for the console hardware.

On a different note I am pretty convinced that N21 cannot be 500+mm^2 @ 3080/3090 performance. The money is just not there for that large a GPU. A wafer of N21 dies @ 500mm^2 would create 83 good dies. If all bin to 6900XT requirements then that is around $58k in revenue (split between AMD, retailers, distribution etc). If they used that wafer for Zen3 dies instead they would make 782 good CCDs which even if used in 5600X's would generate around $230k in revenue (again split). I think that kind of disparity is too much for AMD and their shareholders to swallow.

That doesn't line up with anything leaked recently. bit-tech, for instance, cite videocardz which list 80, 72 and 64 CU models on Navi 21 and Navi 22 coming in at 40 CUs.
https://videocardz.com/newz/amd-radeon-rx-6900xt-to-feature-navi-21-xtx-gpu-with-80-cus

So where did you get your list?

I am guessing he is just speculating, but it wouldn't be the first time that AMD have kept their perf well under wraps. Remember the 4870 with the guaranteed 480 shaders?

This reminds me of the 6970 - AMD kept the specs close to their chest until very close to launch and everyone had decided 1920 SPs for absolute definite (and I was a lone voice claiming 1536)... then when real performance numbers started to come through people were claiming AMD were sandbagging and it was 6950 numbers.

EDIT: Not to say anything I'm saying now is in any way right - I'm just being realistic - I got my info back then from someone who worked in game development and had the cards to test.

Hmmm where did you get that?

Same source coreteks coprocessor came from, rear entry point. But one can dream right

6900xt > 96CU Amd exclusive initially
6900 > 88CU Amd Exclusive initially
6800XT > 80CU Amd reference only at launch, AIB shortly there after
6800 > 72CU AMD reference only at launch, AIB Shortly there after

No i think it will be 80 CU but the performance of those 80 CU's will be higher than some people are suggesting. that is it will be more, higher up the tier than a 3700.

We've still got a few weeks before consoles, I don't think we definitely would've seen leaks yet.

Sargatanas2511 was saying the cards could possibly be available to buy on the "reveal", 28th October.
If that was the case, stock would be on the way to retailers now, with a good chance of some leaks.

It has been reported that retailers have received some (limited) stock of 3070 cards which releases on 29th October.

Re . The consoles, they release on the 10th and 12th November so there isn't much time after the reveal.

 

[Kirby Wurm]

Perhaps AMD will release one SKU prior to the consoles to make good on their aim?

 

[five8five]

Just saying what was said. Nothing more than that.

I am hopeful it'll come before the consoles but if it doesn't it's not the end of the world.

I'm just meaning, are AMD classing the reveal as releasing before the consoles to cover that base?
As I said in another post, there isn't much time between the reveal and the consoles releasing on the 10th and 12th.
Assuming it's not a limited stock release, volume shipping would have to have started. ie containers.

I suggested that a few weeks ago but the latest rumours seem to indicate three SKUs.

I never said this will happen or anything, just that AMD have said they will be available as the first RDNA2 product. I mean it could literally be a paper launch of one single card or it could be a hard launch of a whole stack for all I know. Or it could be pushed back "due to ongoing global issues".

 

[LoadsaMoney]

They should be released, within 13 days of the reveal.

AMD can't get away with pretending that a "reveal" is classed as a "release". Fanboys on both sides would take up pitchforks against them.

Container shipping from China to the UK is roughly 6 weeks. So they either on the water already or are being air freighted if they intend to release them in the next few weeks.

If bandwidth mitigation in the form if Infinity Cache works well

Infinity Cache I find confusing - unless it is very different to the information so far it has no place on the PC and will be a poor crutch that will only work some of the time - while a valid technique on consoles due to the architecture differences and that console game developers will work with it in mind from the ground up.

Is there a source for this please?

If they're air-freighted then it'll probably be a limited stock release like the 3080/90.

Hypothetical - and a crazy idea that's been lurking in my head for a while now

What if the reason AMD have kept wraps on the top SKU is because its a 5nm mcm design?

Bonkers right, but what if

There is a small possibility AMD are leveraging 5nm at least for a surprise SKU - TSMC 5nm is actually in a pretty good place making this somewhat feasible though unlikely because it wouldn't be commercially viable for a limited run GPU but possible they might run a "pipe cleaner". AMD themselves have stated 7nm but the place 5nm is in it isn't an impossibility.

I find a surprise MCM GPU very unlikely as unless someone has made an amazing hardware breakthrough then outside of general compute use there would need to be wider development changes really including at OS level and we should see signs of that at least a year ahead of such GPUs as it was tested.

I just have my doubts that if the card Lisa Su showed was actually a 6800xt that it would be just 72CUs.
A 3 fan, 2.5 slot card for just 72CUs? An 80CU card would seem more appropriate if that rumor was true.

But we will see in a few days.

what absolute drivel.

Its so bad it made me chuckle. Like hambugs napkin maths.

 

[EastCoastHandle]

I wonder if AMD will intro a Ryzen 5000 series with a Radeon 6000 series cards in their reviews next week? And completely do away with intel CPUs? I wonder how much such a system would cost? Less then $2k?

That would make sense of course. But looking at potential projected power draws of the top navi, which could be around 320-360W, a three(3) fan 2.5 slot is bare minimum by the look of it.

Water cooled edition could be incoming to cool that puppy,
