Question Speculation: RDNA3 + CDNA2 Architectures Thread

[uzzi38]

Man I have been dying to make this one for a while now.

First rumours for RDNA3 are here so new thread time!

Just going to start off with this one for now: kopite7kimi on Twitter: "@VideoCardz Ah, I mean a simple mcm design with 10240 cores is not enough. Because the lift from RDNA2 to RDNA3 is much bigger than from RDNA1 to RDNA2. We should expect many big improvements in GFX11. 🤔" / Twitter

No wonder Nvidia is ahead if these are the actual salaries AMD is offering.

Those are the estimated Indeed.com salary ranges. If you look at the original posting on AMD's website, the actual salary range is $128.8k to $193.2k depending on experience level. I'm not a software guy, but that seems pretty competitive to me for that location.

If we use the data on this website to compare Software Engineer salaries then the two companies offer comparable wages:

ok, that makes much more sense for rather specialized needs.

All The Watts!! is alive.

RX 7800M XT 60 CU 16GB 165W
RX 7800M 54 CU 16GB 150W
RX 7700M 48 CU 12GB 140W
RX 7900S 60 CU 16GB 135W
RX 7800S 48 CU 12GB 120W

RX 7800M XT ≥ RX 6800

So 60CU max down to 48CU. Specs look legit and what I expected.
Performance will depend on the achievable clock within a given TDP.
According to TPU, RX6800 clocks at 2218MHz median and 2205MHz as average.
If N32 manages higher clocks, then It will be faster.

That's similar to RTX 4080 laptop.

 

[GodisanAtheist]

Not understanding the 7900S vs 7800M XT.

Wouldn't the higher TDP but same core config 7800XT end up faster than the 7900S?

 

[Ajay]

Geez, the RX 7800 XT (non mobile) better be > 6900XT or what is the point.

 

[jpiniero]

N32 lives?? Why I never. There's still only one N33 laptop out there that I've seen (the TUF with the 7600S) so you have to wonder what's really going on.

Performance might be similar? But better binned so a little less TGP.

The same situation can be seen with mobile N33, so nothing new.
7800M XT will be a bit faster, but 7900S will be more efficient.

I really don't see it making much headway in laptops, but this means there will be N32 cards, maybe we will get some info on those from AMD soon.

I was thinking the opposite. If they are moving forward with N32 now, it has to be because they got enough laptop OEM interest to make it worth their while.

@ 189W TDP (or TBP)

Anyway, assuming 7800's TDP is in ~ 250-300W range and the clocks match, it could easily catch up 6950xt.
And there probably no N32 "XT" either.

UPD:
RGT was told by a "couple of different sources" (i.e. L.Su and F.Azor):
* ES board performance is 19,000 mysterious "points" (probably TS graphics score?)
* GFX clocks ~ 2600mhz and 250W (275W TDP ?) power
* they were quite confident to initially target the 4070's price
* late Q3

Any views on how it stands now?

He mentioned 189W as peak power, but before that he said 165W for 7800M XT.
So either that is some spike, which tend to be over the max TBP or that 165W is without Smart shift which is another 25W.

250W is also TBP for RX 6800. With that clock I expect ~20% higher performance at most and that is between 6800XT - 6900XT in raster, so performance and perf/W is not very exciting.
Asking the same price as RTX 4070? That's too high.

Yeah, hope they going as high as 6800 launch price at the worst case.
I think this is how they revised lineup will look like. Basically naming shifted half a tier, i.e. 7600 and 7800 are full fledged N33 and N32, whereas XT versions will be based on N32 and N31 gpus respectively, so that they can keep the 6000 pricing model.

I ran Lies of P's demo with my 6800. Half of the pipelines in a single frame don't have enough registers, resulting in incomplete occupancy. I'm getting jelly of RDNA 3's registers and caches. If N22 is correctly priced and clocked, it should be an attractive product with 16GB VRAM.

Fixed It for you.
N32 could be great, If the price is right, but for me that would have to be $499 at most.

Found another N33 laptop - Dell is selling an Alienware with the 7600M XT. Which is the full model. Not sure how many Dell plans on selling though given it's like 2 grand.

This doesn't tell us much.

Here are 2 models from Alieware's website:
Alienware m16 Gaming Laptop
Alienware m18 Gaming Laptop
CPU: AMD R7 7745HX, R9 7845HX and AMD R9 7945HX or from Intel 14C20T -> 24C32T
GPU: 7600M XT, RTX 4060->4090
Memory: 16->64GB
SSD: 512GB ->8.5TB for AMD or 512GB->8TB for Intel

But RX7600M XT can be paired only with R9 7845HX or i7 13650HX. Other GPUs or CPUs have similar limitation.
They ask $2,199.99 for R9 7845HX, 7600M XT, 16GB DDR5 and 1TB SSD. That's a lot.

N32 apparently shown by AMD in B-Roll video, without naming it:

Navi 32 collecting dust at AMD HQ With no formal announcement, AMD casually shows its next-gen GPU during an interview. Forbes had a chance to talk to AMD CEO and President Lisa Su about the past and future of the company. This video is actually not very fresh, as we are looking at content...

Honestly it doesn't bode well for N32 that AMD isn't excited to talk about it at all. I ha e a cousin that no one in the family wants to bring up. Guess how great his life is going.

Maybe it's because they are still clearing out and excess of RDNA 2 stocks.

And they were excitedly talking about which RDNA3 product?
N32 looks like a pretty good GPU with 16GB Vram, but price is a key factor.
Honestly, this could be one of the better options this gen depending on price.

 

[GodisanAtheist]

I dunno, seems like guerilla marketing buzz if you ask me. Why would an N32 die be sitting there amongst a bunch of CPU dies in some curated CEO interview with a deliberate close-up slow pan etc?

Figure it was deliberately filmed and put out there with some plants in the media brining it up and trying to build some quiet low level hype for it.

If you think AMD is going to give you a great price on this GPU for its level of performance then you haven't been paying attention. These dies are using N5 wafers, which means every one of these is roughly 3 Zen4 chiplets they didn't make instead.

Keep in mind this is the same company that up until the day before the release wanted to charge $300 for the 7600. Even with the last minute $30 price cut, it's still too expensive by at least $20, but probably more like $50.

I'm expecting them to align their pricing to whatever NVidia is charging for a rough equivalent. If this squares up well enough against the 4070 Ti then expect $700 at the cheapest.

Sometimes, the problem is that people can't tell the good news from bad news, or good price for bad price.

From 6600 XT at $379 to 7600 at $269, that's a 30% price drop, while the inflation was 10% last year.

40% improvement in price performance over 2 years is a pretty good news, IMO. But there were some children throwing temper tantrum, as if they got socks under the Christmas Tree instead of a live pony they expected.
