confirmed: AMD's big Navi launch to disrupt 4K gaming

3 SKUs rumored for RDNA 2

  1. 275w - 80 CU @ 256bit (16 GB) ~= RTX 3080
  2. 225w - 40 CU @ 192bit (12 GB) ~> RTX 3070
  3. 150w - 32 CU @ 128bit ( 8 GB) ~< RTX 2080ti
EDIT:
custom 80 CU skus from AIBs likely to have unlimited power target targetting 3090 performance (& price) ??

( So what happened to the 60 CU sku ? Did the short price gap between RTX 3080 & RTX 3070 scupper AMD's plan for a 60 CU sku or was it never in the works !? )

A twitter user today published on social media the preliminary specifications of what seems to be a custom AMD Navi GPU based on RDNA 2 architecture.

16GB GDDR6
255W TGP

~2.4 GHz (Game Clock)

The TGP (total graphics power) of 255W is more than likely for the custom AIB variant. Bear in mind that TGP is not equal to TBP (total board power). The TBP will be higher as it accounts for all components on the PCB. Also keep in mind that Big Navi has a USB Type-C connector, which on RTX 20 series required 30W alone.

We are almost there. 8 more days lol. As I look back at my life I truly believe all is meant to be. Me not being able to snag a 3080 after checking everyday has been for a reason that reason is I must #WaitForBigNavi.
 
I'm just going to sit here schlumped with my face close to the monitor waiting for Brent's assessment of these cards. I will cross my fingers this release will be kittens and rainbows because if AMD can have a product that is available and worthy of purchase they will have won a spot in my computer, ...........maybe.

If you can get one before the unwashed masses of crypto miners drive the price of the cards "to the moon...

Actually this time. Nvidia has better hand in crypto I believe. RDNA is more gaming oriented so I think gamers might have a better shot lol. Since ampere is more compute oriented this time around. Almost like amd and nvidia swapped hands haha.

Update from same twitter user:

AIB Navi 21 XT cards can go upto 290 watts TGP (memory + gpu & not the rest of the card)

(AIB cards are expected to release in 2021 as per Tweaktown's sources)

If AMD really has a Navi 21XTX card up its sleeve, then power target is likely to be higher than 290 watts TGP for that card

Patrick Schur (@patrickschur_) Tweeted:
- Max. TGP of Navi 21 XT is 290 W.
- AIB partners are testing different TGP for their cards.
- The ~2.4 GHz was achieved with an AIB partner card. So assume that the card was slightly overclocked.

Absolutely not true, the 3080 is not very good at crypto (it's decent at hash rate, but sucks power) and the 3090 is an even worse investment. The 5700 is still the best, followed by the 5700XT... NVIDIA cards were much further down. The 3080/3090 are finally getting decent hash rates, but they do so using more power, which is not optimal for crypto. You want the most hashes per watt and nvidia cards are not (and haven't really been) where it's at. The only reason people were scooping up nvidia cards during the mining craze was because AMD cards were sold out, and even though they weren't the best, they were better than nothing.

3080 is about 20% better than a VII @ hash rate, but over 50% more power. Unless you're very constrained on physical space and have damn near free power, it's not worth it. And by free, I don't mean solar, because even solar farms are energy constrained by how much solar they can generate. I mean you're getting really dirt cheap as much as you can use power. It is about on par with a Vega 56 as far as hash/watt.

Some testing that I've found, these aren't mine but should represent close enough:
2080ti - 52.5MH/s - 180watts
3080 - 96MH/s - ~248watts
5700 - 51MH/s - ~140watts
VII - 81MH/s - ~210watts

If you divide it out, the 3080 has now caught up to the 5700 and 5700xt for hashes/watt (or WATTS per MH if you prefer).

Since ethereum is up a bit right now, lets do the math on payback:
@ 96MH/s you would gross $2.32 a day... I estimated $0.12 for electricity (that's what I pay on average), which leaves you about $1.72 per day. This is about $52 a month. If you find one at MSRP $700 / $1.72 = ~407 days. So if you were to invest in a 3080 for mining it would take you over a year of running it 100% (not including AC for your house or w/e other overhead) to get payback.
If you only paid $0.08 in electricity you'd end up netting $1.92 per day, so 700/1.92 = 364 1/2 days! So pretty much a year.

Anyways, all this to say, it's probably not on most miners top list so you just have to compete with bots. Of course the crypto market could boom again and all cards sell out and skyrocket, or it could tank and a massive influx of old cards (the hold outs) may hit used markets. This is only representitive of today, last week the #'s would have been worse, 3-4 months ago they would have been more favorable.

Some power calculations done by Igor of Igor's Lab:

To get a fair comparison with NVIDIA now, you have to look at the whole thing in its entirety.

I had already done the math for the GeForce RTX 3090 and was almost right on the watt. With the actual GPU power (according to NVIDIA’s Thermal Design Guide) of 228 watts for the GeForce RTX 3090, I ended up with only 2 watts difference.

I transfer now the former calculation once to the GeForce RTX 3080 for better comparability:
that’s just a projection on my part, but it’s plausible.

Table02-1.jpg

So we see that the actual power consumption of the Navi21 XT should be about the same level as that of the GeForce RTX 3080!

what happens now with the board partner cards and the factory OC?

Table03-1.jpg

With the smaller version Navi 21 XL the calculation would look like this, because only memory with 14 Gbps is used and also the clock rate of the GPU is moch lower:

The power consumption numbers here is very similar to what to information sent to me last week from people at 2 AIB's. I just didn't share the numbers, but said not much room for OC and also mentioned PWR ~ 3080. This means AMD are going all out :)

I think he is overestimating it so it doesn't look bad either way. Look at 5700xt its only 40w for rest of the stuff, yea they are using more memory. But he is being quiet liberal with his estimates. Not sure how we go from 185w 5700xt + 40 watt for rest to almost 80w+ for rest with RDNA 2. We shall see but I would expect overall it to be 30-40 less then what he is estimating.

( So what happened to the 60 CU sku ? Did the short price gap between RTX 3080 & RTX 3070 scupper AMD's plan for a 60 CU sku or was it never in the works !? )

Rumor from coreteks on Navi 21 (80 CU) SKUs:
  1. N21 XL = 6800 vanilla = 64 CUs, 220w TDP, 290w? TBP
  2. N21 XT = 6800 XT = 72 CUs, 255w TDP, 290w?? TBP
  3. N21 XTX = 6900 XT??? (AMD exclusive), 80 CUs !?!?!

He claims that Lisa Su displayed the 72 CU sku
looking at the pictures I can tell you that the one that Lisa Su was holding during the 6000s event last week was in fact the 6800XT. The 6800 is slightly different although it also features a triple-fan design. The 6800 seems to be 2 slots while the 6800XT seems to be 2.5 slots judging by how the shroud covers the bracket (unlike the 6800 which has the bracket rolling over it), although it’s difficult to say exactly given the angle of the pictures.

Sometime people need to really read their own article. He still is sticking to 10-15% faster then 2080ti for 6900xt and then went on to say lisa showed 6800xt which was more then 20% faster then 2080ti and almost matched 3080. I am like scratching my head lol. I think he doesn't want to go away from what he said 6 months ago, if its faster all good. If its the same he can say I said so lol. I like him but he is sticking hard to what he heard a while back lol.

Well now that I read the Igorlab latest article it makes sense. AMD is holding back and limiting the performance in drivers to hide final performance it seems and that is what AIBs were reporting to coretek 15% a while back lol.

Videocardz has info on the next tier AMD card

The Radeon RX 6700XT is expected to be 40 CUs (2560 Stream Processors) & 12GB GDDR6 192-bit memory.

The current plan is to launch them in January. According to sources, AMD has recently decided to launch these GPUs quicker than previously planned.

https://videocardz.com/newz/amd-radeon-rx-6900xt-to-feature-navi-21-xtx-gpu-with-80-cus
 
So, is anyone else thinking Lisa Su showed us the 6800 XL card at the end of the Zen3 launch?
Now this is wishful thinking, but at the end of the Radeon Presentation " Now with all these options, we still have one more for you. Introducing the 6950XTX Dual. Dual 6800 chips fused on one PCB by Infinity fabric/cache and 32GB of HBM2, so they act as one without mgpu driver level support. Priced at $1499. Available also in January."
I know I know. It's just been so looooooooooong. I just want AMD to pull something out big this time around. Just let me dream, let me dream....;)
 
Jebuz Fkin Christ. Every radeon launch is like this. OVERhype followed by reasonable performance. Net result is a bunch of people disappointed because they have expectations based on hopes, dreams and hallucinations.

Calm your tits.

I'd agree with you, the Polaris and Vega threads are hilarious to look back on in the amount of over-optimism (with a few reasonable folks trying to slow the hype train being railed against). If I had the time, I go back and dig up some choice posts to shame some members still here. There are certainly some hyperbolists out there for RDNA 2 who will be disappointed, but I have a feeling 6000 series is going to be far more competitive than we've seen from AMD in performance in years. We may be looking at a 780 vs 290 situation. Don't hold your breath on pricing, however, since remember "MSRP" is essentially just a marketing number for nV/AMD/AIBs at this point: street price of 6000s will be far higher than the MSRP announcement next week. I'm guessing the line up is going to look something like this in rasterization (subtle variation on my earlier guess):

6800 XTX (or 6900 XTX?) - 5-10% above 3080
6800 XT - 10% below 3080
6800 XL - Equal to 3070

It remains to be seen, but I have a hard time believing the compensatory caching on RDNA2 will be as good as an old-fashioned big mem bus. I think nV may end up scaling better at higher resolutions. And as for RT, there will be no competition with Ampere: it's essentially a tick on the 6000-series feature checklist.

I wouldn't say hitch your tits and pucker up just yet, but I'm rationally optimistic on performance. Even so, street pricing and availability will be dire. I'm guessing no one will see any of these cards in their hands until 2021.

The last time AMD pulled off a performance surprise was 2002 and that’s when they were still ATi. It’s long overdue.

What's the obsession with keeping the numbers big? I don't even know what XT means. Is that mean the card is better or worse (rhetorical question). It's just letters. To me it's simpler to just be 6500, 6600, 6700, 6800, 6900 - at least this would give some sense of scale.

But you know, no one wants to buy the 6500 because the number is small I guess. At least the 6700 is kinda close to the 6800XT, right? It must be almost as good :facepalm:
 


there's a new update on the maximum frequencies that Navi 2X "Big Navi" GPUs can run at by Igor's Lab. The information comes to him straight from an AIB partner of AMD and a very special one at that who has provided a BIOS of its next-generation Radeon RX 6800 XT custom board. Igor used the "MorePowerTool" to evaluate the BIOS and found out that the boost clock is set to 2577 MHz

I don't know about you, but I'll only buy video cards with at least two XXs. Obviously, adding a vowel to the name means it's faster than a non-vowel card. Zeroes do a similar function: they add speed.

While you are correct, nVidia's 3000 series are not living up to the marketing performance increase outside of RTX which is still very niche. Combine that with the absymal improvement in raster from the 1000 to 2000 series that puts nVidia in a worse position than they have historically been.

Yes AMD has a history of flubbing GPU launches and being uncompetitive since the HD5970 in 2009 (not 2002). However, AMD is under new management and they have proven themselves capable of rising to the occasion.

Time will tell, and since its near impossible to get a 3000 series, why not wait a few days and see?

As today’s announcement is not a full tech deep dive – like the Zen 3 announcement, the deep dive will come closer to launch – AMD is only sharing some high-level specifications of the new cards. But with information on the number of CUs, memory support, and power consumption now in hand, we have a good idea of what AMD is bringing to the table,
