Big Navi might still be faster than the 3080

[AndreiArgeanu]

Summary

Listings in the new Radeon Open Compute allegedly show some of the specs of the GPU's AMD might launch this fall, showing that the Big Navi GPUs

The listing hints that the GPU will feature 80 compute units (CUs) and a 256-bit memory bus. If each Compute Unit (CU) in AMD's RDNA 2 architecture still equates to 64 Stream Processors (SPs), that means Big Navi will 5,120 SPs. 

If this is true, and if the GPU runs on TSMC's latest 7nm process, the flagship RDNA 2 processor could deliver Nvidia RTX 3080 levels of performance. After all, AMD has already promised that RDNA 2 will deliver 50% more performance per watt than its first generation RDNA architecture. 

The firmware update also references a graphics card codenamed Navy Flounder, believed to be Navi 22 or Navi 23. This mid-range GPU features 40 CUs and a 192-bit memory bus, according to the listing, which amounts to 2,560 SP.

 

This card will likely arrive as a replacement for the AMD RX 5700 XT, but with its newer RDNA 2 architecture, it will support real time ray tracing and be capable of gaming in 4K. We don’t have any details about performance just yet, but it could give Nvidia’s RTX 2070 a run for its money. 

My thoughts

 It's great to see that AMD may finally bring some competition to nvidia after all these, and who knows, maybe even decrease GPU prices. But I doubt it. Still even if they can't compete with the 3090 there's a chance (if this is true) that AMD could potentially win over the GPU market, of course, if they offer better value, which they most likely will. This and the extra v-ram their adding to their cards gives me hope.

this is what they need, but it doesn't feel particularly likely. they can leave the 3090 safely in the lead for now, but if they did manage to catch the 3080, the titan class card would need to be next on the chopping block.

 

one can hope I suppose

[Spotty]

Everyone wants AMD to be able to compete with a current generation Nvidia high end card, but let's not hype it up too much just yet. Just be patient and wait a month until the card releases and there's independent reviews for it that will undoubtedly compare them to the Nvidia cards.

That's Nvidia's marketing dude. AMD needs to get there own ideas like pre-order exclusive coolers or something.

You only get coolers if you preorder. Excellent I like it.

AMD Radeon RDNA 2 Big Navi RX 6700 XT Avengers Edition

 

Supposedly Big Navi will be featuring hardware ray tracing, hence the +50% performance uplift from previous gen.

Nvidia like Intel has reached some sort of tech limitation where they are resorting to making the chips bigger to get more performance while drawing much more power. The 3000 RTX series is basically the Titan RTX with varying amounts of VRAM manufactured using newer methods that are supposedly cheaper.

 

I think AMD has a good chance here. Just not sure about their supply capacity.

Tech Yes City mentions undervolting the 3080. He drops the core clock by about 100MHz. Easily reduces power consumption by 100w, to ~220w. Performance only drop by about 3%.

 

The question is why Nvidia needs to go way outside of its norm of 250w TDP with the 3080. They can keep the same old 250w TDP and the 3080 would be almost as fast.

 

Everyone is rushing to upgrade their PSU to 750, 850w units.

Ah can we please have a Pro Display XDR move? Coolers sold separately.

I don’t know if you were being sarcastic but in case you weren’t:
 

No, the two are independent.

 

50% higher performance per watt comes from architectural improvements and the improved TSMC N7P process which RDNA2 will be using. 
 

Ray tracing is a side benefit of RDNA2. The main thing to focus on is substantial performance uplift from AMD competing with Nvidia.

 

AMD now has the clock speed advantage that Nvidia willingly gave up to be on Samsung and AMD is going to take full advantage.
 

We’ve already seen RDNA2 can clock at 1.8GHz and 2.2GHz.

Sounds like they know something we don’t such as how good RDNA2 is.

Hence why the 3090 isn’t a Titan. Could you imagine a 48GB G6 fully enabled GA102?

 

That’s the best card Nvidia can make on Ampere for gamers. The 3090 isn’t fully enabled.

Nvidia confirmed were getting a 3090 as a "titan class card" tho, I thought that means it was this gen's titan

 

Unless there's some kind of "second gen ampere" or a super/ti refresh to slap onto the 3090?

Of course there'll be. Why not?

Could they? Yes, most likely. Will they? I think it depends on what AMD brings to the table. If Big Navi really does compete with the likes of the 3080 or 3090 for that matter, then yes, I could see Jensen launching a higher tier card than the 3090. But if AMD does not, I do not see them going any higher than the 3090, as its AIB cards are already reaching nearly $2k... 

[suicidalfranco]

hope that's true, cause been using a 1060 on my system after my 390 died and... compatibility with Ubuntu is still trash. Tried both propriatary and open source drivers. For some reason it goes bonkers with two displays plugged in.

00f, make me feel good for trading my 1060 for an RX 580 when switching to Linux.

And hopefully they manage to have working drivers this time around.

Yeah that's what I was alluding to. A Titan version of the top Quadro card.

[Moonzy]

wait for benchmark

don't hype it up and get disappointed like the 3080

[Trik'Stari]

AMD actually making an effort and not shooting themselves in the foot by being the "budget" option on purpose?

 

I'll believe it when I see it.

 

Hopefully they'll finally make something that beats out a 1080ti so I can upgrade finally.

[AdmiralMeowmix]

Don't hype up based on these alone because old Navi had better specs on paper than nvidia's offerings, by al laccoutns it should have performed amazingly well. But it didn't and was performing way udner spec. So I cant trust AMD's "specs" claims.

Yeah, I agree.

 

Also (and obviously this is speculation and could be completely off base), but I think there might be a few others based on the same silicon [GA102]; with varying frame buffer sizes (VRAM) being the real differentiators between SKUs/Models (and slightly less CUDA Cores when compared to the full fat die/chip/GPU/offering).

 

RTX 3090                            [  10,496 CUDA Cores,   24GB    ]

RTX 3090 Super                [   10,560 CUDA Cores, ¿xxGB?  ]

RTX 3090 Ti                      [    10,688 CUDA Cores, ¿xxGB?  ]   

RTX "Ampere" Titan         [     10,752 CUDA Cores,    48GB   ]
