Something to look forward to: With only a week until their official reveal, AMD's Big Navi graphics cards keep generating a lot of buzz, and rumors and leaks abound. Everything points to an exciting launch with powerful GPUs backed by ample memory and quite an appetite for electricity, just like Nvidia's latest offerings.

Earlier this month, AMD unveiled the Zen 3-based Ryzen 5000 series of desktop CPUs with absolute confidence that this time they'll take both the productivity performance and gaming performance crowns. The company has been relentless in delivering significant performance jumps since the first Ryzen release, which is why it gained a lot of mindshare in the eyes of enthusiasts, with 25 percent of Steam users now owning a Ryzen CPU.

AMD is also preparing the launch of its RDNA2-based Radeon 6000 series graphics cards, which are set to be revealed on October 28. As we inch closer to launch, rumors seem to be driving enthusiasm around the new hardware to a point where we might see the new cards getting sold out just as fast as Nvidia's RTX 3000 series.

When AMD CEO Lisa Su previewed the Radeon 6000 series, she said that these are geared for 60+ FPS at 4K in popular titles like Borderlands 3, which means they'll pack some serious power. Over the weekend, software engineer and reliable leaker Patrick Schur posted on Twitter the purported specifications of a Navi 21 XT graphics card that he claims were sourced from an AIB partner.

If these turn out to be accurate, "Big Navi" will be a well-deserved moniker for these cards, as this seems to confirm earlier rumors that the upcoming flagship 6900 XT will feature 16 GB of VRAM, which is more than you get with Nvidia's RTX 3080.

It's widely expected that the Navi 21 XT will be positioned as a direct competitor to the RTX 3080, which is quite power hungry with a TGP of 320 watts. A leak in the macOS Big Sur beta code showed before that Navi 21 is going to have 5120 cores, which means AMD has done some architectural wizardry for what appears to be a Godzilla GPU.

According to Igor's Lab, the 255 watt figure as shown above is just for the GPU and the Samsung GDDR6 memory (235 watts + 20 watts). Once you add in MOSFETs, fans, and other electronics, you get an additional 65 watts that bring the total to around 320 watts, so effectively on par with an RTX 3080. Some custom cards are expected to need as much as 355 watts.

The more interesting tidbits from the last batch of rumors are about availability. Considering Nvidia hasn't been great at managing supply and doesn't expect the shortage situation to get much better in the coming months. AMD could take advantage of this wide window, and Igor says AIB partners have had an easy time with implementation as Big Navi's board design isn't all that different to Navi 10. Better yet, it looks like AMD is already busy implementing measures to cope with demand and prevent scalpers from ruining the launch.

After trying to buy a 3080 at launch I'm now eagerly awaiting to see how big Navi compares. If it matches the 3080 at 4K and matches or exceeds it at 1440p then it would be very tempting, assuming it's even possible to get one, which I wouldn't hold my breath over. The only thing that would hold me back is DLSS and ray tracing implementation. If they haven't caught up in that regard then I'll probably just stick with Nvidia for now

They already have 3090 that's only 15% faster than 3080 for double the price. It seems unlikely that they're going to make a meaningfully faster 3080ti/super until late 2021 at the earliest.

Unless TSMC 7nm is far superior to Samsung 8nm. But if I remember Moore's LawIsDead correctly it's unlikely they would make one range across different manufacturers. Unless of course a Ti version doesn't count as being part of the range that is currently launching.
 
I have read RTX 3080 3090 is only meeting 10% of the demand, if RX 6000 do not have a supply problem... it will take a huge chunk of that, me included. The yield of the latest RTX is a joke....

It's actually on average only 10% faster... there is no room for a 3080Ti/Super this time around.
Their only move is to speed up the next gen, the 4000 series need to come sooner, if they lose the performance crown.
They will however for sure lose on market share and mind share, even if the biggest Navi is only as good as 3080.

Since Nvidia has no supply, beating the 2080 ti sadly big navi will have no competition. It could be slower then the 3080 and priced at $900. Only a few thousand 3080s exist in the wild. Hopefully AMD doesn't get greedy.

I think based on this simple fact, AMD truly is trying to help the end user and Nvidia is just enjoying being at the top for too long, 40% of Nvidia gamers should switch to new RX6000 series just so that the world becomes a better place. We the end user need to have a place where we can get good deals, buying power and the ability to spread the love for our passion without having to sell your liver to get a new PC... new incentives, new competitions sponsors, streamers all working together for the over all good of the end users experience rather than just a competition to who is best ... If Techspot bought 5000 cards RX6000 and sold them off at a discount one card per user, even made a small profit, that would be an amazing idea for the future of Techspot and the end user

Twice the size of 3090, on trolley wheels this time?

There maybe tough times for nVidia, since RX6000 is expected to fully support CrossFire, while nVidia pulled SLI from 3080 and below. And nVidia SLI for 3090 is a joke, given how huge the card is.

Expected by who? CrossFire as a technology name/brand has been retired 3 years ago and Navi no longer has any support for it. Only DX12/Vulkan titles with explicit multi-GPU support can use multiple Navi GPUs, but this solution is GPU model-/brand-agnostic (in theory you can pair a Navi and a Vega card, or an Nvidia card with an AMD one) and only supported by a handful of games. There's hardly any reason to revive this solution, at least for games. Compute tasks can make use of multi-GPU setups, but they, on the other hand, don't need special per-app profiles and can distribute the load across cards themselves.

Multi-GPUs are dead in gaming. They might sort of come back as multi-tile/-chiplet GPUs that appear as a single card to the system (Imagination Technologies has created such a solution), but both CF and SLI are on their way out.

Read on twitter that Navi 21 has IF that is probably going to be used for multi GPU.

Admittedly there are so many conflicting rumors right now about Navi 21 so I guess we‘ll find out soon enough.
 
If these are actually good and AMD can keep the market supplied, they have very good prospects of getting a great market share. Nvidia created a lot of hype with their price/perf of RTX 3080 but failed so far to actually deliver the product to the consumer. It will be really funny if AMD reaps what Nvidia sowed. It would also improve my chances of actually getting an RTX 3xxx for my Gsync TV...

lol. SLi and Crossfire are dead and buried. Where did you hear AMD and game devs were still supporting it after they stopped supporting it in their drivers?
 
Never had problems with Radeon drivers. But I did have problems with both Nvidia and AMD drivers regarding their size. It's just sick that video car drivers are so huge. It must be swelling with bloatware, poorly optimized crap and unnecessary crap inside.

AMD Drivers...... around 400 MB
Nvidia Drivers.... around 600 MB

That's just botch. Drivers cannot be that big unless there's a huge amount of poor and lazy programming with lots of unnecessary libraries and copy/pasted code. Which is the last thing you want in video drivers.
