AMD's "Big Navi" reportedly has 2x as many CUs as Radeon's RX 5700 XT

2x as many CUs, with architectural enhancements and higher clocks. What's not to like?



Read more about AMD's "Big Navi" RDNA 2 flagship reportedly featuring 80 CUs.

The price it will be.

I half expect to see some beefier cooling in the next gen consoles. But shrinking to a smaller node and going multi die on the CPU is going to make them easier to cool, so not on the same level as PC.
I hope to hell that they really have done away with the blower style coolers this time around. Otherwise i cant see them clocking much higher than that and hopefully overall better quality.

More rumours, I demand a Die Shot!

As Jay said today, if big navi is 50% faster than RTX 2080ti, this would mean next big navi cards would have to be at least 300% faster than 5700XT.

I don't think that is possible, not even x2 on the CU units and increasing core clocks.

Now, the big issue here will be prices and drivers. AMD will probably launch big navi at prices around 700$ (at VEGA VII prices). This is my guess. And the drivers are awful. They are a disaster. A enormous one. With a lot of bugs and crashes.

What about Nvidia? Well, it's said that the 3080 will be 20% faster than the RTX 2080ti according to a youtuber called "Moore's law is dead".

I think, and this is my guess, that Nvidia will win AMD flagship with the 3080. And i will say more: no way AMD is going to win the Nvidia 3080ti/super. And consider this: Nvidia will still have the Titan.

AMD should sell their products cheaper than Nvidia, because i don't think they are going to be able to compete in performance. Once you get to a certain performance you need, you care about price.

Not sure how you did your maths, but the average FPS gains I see online for RTX2080Ti vs RX5700 XT are 35%, so the new card would only need to be 203% (1.35 * 1.5 = 2.03) the speed of the 5700XT to be 50% faster than the RTX2080 Ti, IE it would only need to be 100% faster than a 5700XT rather than 300% faster.

(200% the speed of = 100% faster, 300% the speed of = 200% faster, possibly a language barrier thing?)

So if they were able to double the CUs, bump the clock speed and IPC to alleviate the efficiency losses, 50% faster than an RTX2080Ti would be fairly trivial to achieve. *IF* they can double the CUs from 40.

But yep, NVidia could probably go further still, but it's more likely to be in the region of 15-20% faster than AMD's flagship rather than the gap we've seen previously.

No, it's just JaysTwoCents poor math/way of wording things. He released a video this morning analysing RDNA2.

I've tested enough games to see a simple trend with the RTX 2080 Ti. It offers around 2x the performance of an RTX 2060. This assumes that there are no CPU limits or similar bottlenecks.

The RTX 2060 is an RX 5600/RX 5700 competitor. This makes a theoretical 2x RX 5700XT (a hypothetical RX 5900 XT) faster than an RTX 2080 Ti.

I haven't seen his video, but Jay is mistaken if he thinks the RTX 2080 Ti offers double the performance of an RX 5700 XT.

It is also worth remembering that AMD has made radical design changes with RDNA 2. Adding ray tracing, VRS and all of these other changes require changes all across the GPU. Many of these changes will deliver efficiency boosts. RDNA is a starting point, so we can expect a lot more than a 2x RX 5700 XT if AMD has indeed doubled their CU count.

A 300% gain over the RX 5700 XT is very high, but AMD doesn't need that to surpass the RTX 2080 Ti or to compete with Ampere in higher-end market segments. Maybe AMD won't best the RTX 3080 Ti, but they should be a lot closer than any time in the past five years.

From reviews I've seen, 2080Ti is only about 1.5x faster than a 2060 (founders editions) with 2.25x the core count and about 1.3-1.4x faster than a 5700XT. There's always been a case of diminishing returns for throwing more cores at it, but i'd expect a double 5700XT with a die shrink+clock boost+architectural refinements to be at least as fast as a 2080Ti, if not more so.

I want to see a bit more than a good price and drivers this time round. There were mounting pressure issues on the Reference models and huge problems with heat.
Had the world not been rooting for them, they would not have been well received. Imagine your 2080ti was overheating and crashing due to poor mounting pressure, £1200 for something you have to take apart and void your warranty for or roll the dice and get an RMA for a part used/refurbished model that may or may not have the same issue. I want AMD to bring it to Nvidia and start a price war but at the moment Nvidia are still a far better quality and more reliable supplier
