Question Speculation: RDNA2 + CDNA Architectures thread

[uzzi38]

All die sizes are within 5mm^2. The poster here has been right on some things in the past afaik, and to his credit was the first to saying 505mm^2 for Navi21, which other people have backed up. Even still though, take the following with a pich of salt.

Navi21 - 505mm^2

Navi22 - 340mm^2

Navi23 - 240mm^2

Do you honestly think AMD would showcase their fastest, top of the line card in a teaser 3 weeks before the reveal? No, this was the 6800XT. I would almost put money on it.

I would absolutely expect those numbers to be reflective of the 6900XT unless they said otherwise. She even qualified the performance by saying they're still tweaking/optimizing (I forget the exact phrasing), which makes me think they're really saying "this is the best we got right now, but we're still working on the software"

 

[Paul98]

Not bad, not amazing, we don't know at what power, which card, or how much vram. But this does mean it's hopeful for AMD on the GPU side.

I should take a look to see where the 5700xt stands on those titles and not just vs the 3080 as we have seen a wide variation on where AMD or NVidia shines on certain titles

 

[Vope45]

This is the nth time I've seen AMD fans' mental gymnastic, from Evergreen to Hawaii to Fiji to Polaris to Vega It'll likely be 10% to 15% slower than the 3080.

 

[Zstream]

Using TPU numbers for BL3 and Gears 5 this 6000 series part is about 2x the performance of the 5700XT.

In both cases the 5700XT barely beats the 2060 Super so neither game is especially Radeon friendly.

I don' think BA settings DX12 are in TPU, unless I'm reading it wrong.

 

[Midwayman]

Honestly unlikely to go bargain priced. GPU demand appears to be such that it'll sell out at any halfway sane price point.

Based on those benches, I wouldn't consider that bargain priced. Its slower than a 3080. AMD doesn't have feature parity. TBH their history of software support isn't as good. If it went up much more like to $649, I know I'd prefer the 3080. You have to assume those benches are cherry pick too.

Hopefully the all RDNA2 architecture won't have the hangups the Hybrid RDNA 1 had in some games.

According to Eurogamer/Digital Foundry the RTX 3080 also does ~61 FPS in BL3 at 4K with Badass settings.

overclock3d.net shows the 3080 getting 58.5 fps for BL3 at 4K Badass settings. Like I said, people shouldn't jump to conclusions here, there are a ton of variables in play and we need to see the cards in a controlled environment before being able to determine comparative standing with any kind of real granularity.

According to Eurogamer/Digital Foundry the RTX 3080 scores ~81 FPS in Gears 5 at 4K Ultra settings.

Absolutely not. This wasn’t a Radeon reveal. I guarantee you that wasn’t AMD’s fastest card. From a business perspective it would be foolish to do so.

Agreed.

Or they just wanted to avoid Big Navi from getting overhyped like Vega.

Why not, particularly if it's able to beat a 3080 convincingly? It's not like NVidia can do anything about it in response.

I suppose going with a second best card that's a bit cutdown helps level out expectations and does leave room for a big reveal at the actual RDNA2 launch event.

It doesn't change much though. It's not like NVidia wouldn't consider the possibility they didn't show the best card or that an extra few weeks can allow for driver improvements.

 

[Saylick]

Either AMD shot themselves in the foot by showing off a slower GPU as their fastest Big Navi card in a teaser 3 weeks before the announcement, or the part shown was not their fastest card.

Yeah. I think I'll give AMD the benefit of the doubt and go with the latter.

 

[insertcarehere]

?

AMD showing titles they lose in is not something out of the norm.

Not comparable at all, this was 1 Title out of 10 in gaming benchmarks for a 12 core CPU where AMD have spent the entire presentation showing how the CPU beats the piss out of its rivals everywhere else. AMD no doubt tested Big Navi on way more than 3 games at this point and these are the games they show, what does that tell us?

 

[tviceman]

Yes I would expect AMD to show their best hand. Why would they sandbag their own products and presentation when their competitors just released new and well received products? If AMD could outright beat Nvidia they would have shown it today. It's obvious the 6900 XT will slot in between the 3080 and 3070.

 

[Zstream]

I'd like to get stats on the resolution percentages. Does anyone know if I can just take the 4k number in pixels, get the fps per pixel and apply that to a 3440*1440 resolution?

 

[tviceman]

3080 about 10% faster than Big Navi hmmmm
I'm assuming they would want to show their best card and hand picked 3 games.
That said don't know the system configs

https://twitter.com/x/status/1314244138716594176

Exactly. It's probably going to be right in between the 3080 and 3070 with respect to performance in rasterization, but with 16gb of vram. I imagine ray tracing will be an uphill battle for AMD vs. Nvidia this round.

DX12 instead of DX11 results

Just checked techspot (hardware unboxed) and in gears 5 4k ultra they have the 3080 at 72 fps avg and the 5700xt at 41fps. The 6000 is a 78% uplift over the 5700xt in this review. Techspot also tested with the 3950x.

Guru 3d also show a lot of variation in 3080 and 5700xt numbers so I wouldn't say the numbers AMD showed were conclusive as it seems to swing from 90% of 3080 to on par with 3080.

If that is 80CUs @ 2.2Ghz with IPC improvements it seems really poor to be honest and looks like RDNA2 did not fix the scaling issues GCN had. If it is a cut down 72CU @ 2Ghz part then it looks much better.

NV are going to sell every 3080 and 3090 they can put out between now and October 28th (and beyond probably) so if AMD have not shown the top tier card to allow them to show something surprising on October 28th then its not like it matters.

 

[swilli89]

We really need to wait for reviews. People calling for crow eating or making assumptions are just plain wrong.

Gears 5

Hardware Unboxed:


Big Navi: 73 FPS, 3080: 72 FPS

Hexus:


Big Navi: 73 FPS, 3080: 76-81 FPS

Guru3d:


Big Navi: 73 FPS, 3080: 76 FPS


Borderlands 3

PCGamesHardware.de


Big Navi: 61 FPS, 3080: 60FPS

Hexus:


Big Navi: 61 FPS, 3080: 59-62 FPS



Call of Duty: Modern Warfare

PCGamesHardware.de


Big Navi: 88 FPS, 3080: 82.2 FPS


So we have Big Navi and 3080 trading blows. What more can we even say at this point? We know trhe 3080 is a power hungry beast and was somewhat crippled at launch by the lack of higher memory options. Just from the looks of what we have here today, Big Navi with 12gb or 16gb at $700 would be a good competitor to the 3080.

That's exactly my thought. They may be sandbagging as part of their misinformation campaign knowing so few Ampere cards are even going to be available to purchase before their big announcement in 20 days.

They made some mistakes in some of their numbers (e.g. Eurogamer BL3 is 60.9 fps, not 65 fps).

Exactly. I remember hearing this same tiresome whining when 5700XT was teased and AMD only showed Strange Brigade - turned out it was a worse than average game for the card, IIRC.

Most importantly, Herkelman stressed that AMD didn’t state which Radeon RX 6000 graphics card ran these benchmarks. We don’t know whether these results come from the biggest Big Navi GPU, or a more modest offering. (Herkelman also said there’s still fine-tuning left to do before launch.)

Herkelman is hinting that this isn't the top card.

 

[moinmoin]

I'm assuming they would want to show their best card and hand picked 3 games.

How do you (and others) come to this conclusion? AMD has a history keeping the best product for last. Even in this video AMD first went with 3900X, then showed the lower CPUs, and only last showed 3950X. But as a tease for an upcoming event they would show the best possible numbers of the top card? I don't believe that.

 

[Shmee]

Well again this is marketing, should definitely wait for reviews and more info. I hope supply is good though, if it is not, then waiting for reviews might make you miss one :C
