Double up 5700 XT is greater than Turing +20% IPC, and that's before you factor in the RDNA 2 improvements. In terms of raw performance, I think RDNA 2 and Ampere are going to be pretty close for a change. As for ray tracing, who nows. 4x RT performance on Ampere brings it up to usable across the stack, but AMD said they were only releasing RT capability once they could offer it across the entire product stack.

I think we're in for a pretty tight battle this generation.

I refuse to get my hopes up.

Good call.

Has it been confirmed if these are all going to be pcie4 yet?

It's going to get expensive if I need to change my board to get the best out of it.

RDNA 1 is so I have no doubt RDNA 2 will also be pcie4

Is it? I had no idea a 5700 xt was pcie4 somehow that one escaped me

Yup it would be strange for AMD to backtrack on that now.

It doesn't even matter. There is zero performance difference between using a 5700xt on a pcie4 board and a pcie3 board.
That card isn't nearly fast enough to get any benefit from pcie4.

We'd need something at least twice as fast as a 5700xt to start to see any benefit to pcie4 lanes

What, like an 80 CU RDNA2 card

or the top Ampere cards.

If the rumours in the NVIDIA thread is anything to go by, I don't think big navi is going to compete at the top end, certainly not with 3080ti. Ampere with 4x RT performance with 20% IPC increase and crazy die size NVIDIA can achieve with their architecture just don't see big navi as being enough, hope I am wrong.

I can't see Ampere hitting 4x RTX performance in a million years. Maybe 4x in ray tracing, that's plausible.

I think Big Navi with a 5700xt x2 on 5nm depending how it scales could be faster than a 3080ti. Pure speculation ofcourse.

its in Nvidia's interest to have people believe RTX = ray tracing = must buy Nvidia

wasn't Turing supposed to be x10 faster than Pascal without spelling out the niche case in which that might be true when in reality it basically translated to 'a load of nonsense and waffle'

That's what he said, 4x Ray Tracing.

4x RayvTracing would basically just mean that the raster performance is the same with rayvtracing on or off

the 2080ti is already 6x the 1080ti in ray tracing, another 4x on the 2080ti would mean the 3080ti can push 24x the 1080ti'a BVH calculation capabilities

All these numbers sound a bit like marketing gibberish though - the only important take away is that there is no performance hit to turning RT on (Or so says thy rumours)

If you do like numbers though here is another totally useless one. Nvidia said to match the 2080ti RT performance an Nvidia card without fixed function hardware would need 50tflops of compute performance. Therefore if the 3080ti rumour is true, a card with no RT cores would need 200 Tflops of compute to match it

The 2080ti has 6x the BVH capability of the 1080ti, not 10x

RT is a legitimate jump in picture quality. This is a good thing. Not a gimmick. If they can make it viable in just 2 generations, that's actually incredible.

Not looking good if the next Assasins Creed can only do 4K@30 :eek:

on RDNA2 powered next-gen consoles

I see this hype train going but the big question is at what graphic settings is it using ray tracing etc they are load more questions that need answering first.

Ubisoft already ruled out Ray Tracing, there is no Ray Tracing options in Valhalla

Really? I have missed this got a link?

What can the 2080ti run it at?

Ubisoft has always been committed to exploring new technologies, taking advantage of the capabilities of new consoles to deliver the most immersive experience possible, which is why we are excited to be collaborating with Microsoft to bring Assassin's Creed Valhalla to the Xbox Series X ".

"Currently, we can guarantee that Assassin's Creed Valhalla will run at least 30 FPS. Assassin's Creed Valhalla will benefit from faster loading times, allowing players to immerse themselves in history and the world without friction. Finally, Assassin's Creed Valhalla will benefit of improved graphics made possible by the Xbox Series X, and we can't wait to see the beautiful world we're creating in stunning 4K resolution. "

"We will have a lot more to show you about Assassin's Creed Valhalla in the near future, so stay tuned for more information soon!"

This for me is prime internet jump on the bandwagon before its even been shown or confirmed. At least doesn't mean a 30fps cap they are stating a fact it will not drop below 30fps at 4k on settings and quality we still have not seen mind you.

4k30 from a cheap console? That is very promising for the desktop GPUs.
