If I wouldn’t of got my 3080 for £650 before prices went up and I wasn’t so low in the queue on ocuk I’d of probably been cancelling and ordering the 6800xt

looks a beast of a card, if you watch Linus most recent video though I’d be a tad skeptical of the performance comparison chart as it shows the + rage and + smart access memory both in play the latter benefiting only from when you get one of the new amd cpus too

You have a Gsync or Freesync monitor?

Not for the 6800XT they didn't.

I suspect they enabled it on the 6900XT slides because without it the improvements over the 6800XT were pitiful - even with both turned on it's only winning over the completely stock 6800XT by around 9-10% on most, 15% on some.

Equally with the 6800 it is far enough away that it wasn't going to make the stock 6800XT look daft, but would hammer home how much it beats up the 3070 to justify that slightly high (imo) price point.

With the 6800XT however they played it straight against the 3080 with none of the tweaks, probably to reinforce that they really do compete like for like.

I think the performance delta is the point though.

Well for apples to apples which I very much doubt this is, but I was more thinking in the realms of ECH below.

Ignore it. That demo is coded in a way that takes advantage of Nvidia hardware approach. Which uses concurrency with preemption.

AMD's approach is parallel. Meaning they are more efficient if it's all done at one time.

The creator of the demo would need to create an .exe for Radeon.

I'll give you one better. I run the same demo on my 2070S and got wild results just by moving other windows around, or for example clicking the window and making it active (144FPS) VS clicking on empty desktop to make it inactive (342FPS) - the latter gave me considerably higher FPS for no reason at all! In other words, that benchmark gives horribly inaccurate results and I wouldn't use it for any sensible comparison at all.

It appears you need smart access memory which is available on Ryzen 5000 series CPUs to get optimal performance.

Its making sense now, they showed their most competitive GPU on the 8th October (RX 6800 XT), as the RTX 3080 is the main product they need to compete with.

That's a respectable price for it. No need for buyers remorse unless you'd spend 800quid on one.

I agree, I was really going to just get one at launch and think about it later. When the scalper/bots flatlined the launch for 98% of people I sat back and decided to give AMD another chance. £649 is the target but when it goes £700+ I lose interest exponentially.
 
AMD clearly thinks they can win over the big spenders who normally buy Nvidia GPUs, I cant see why not tbh, especially with the lower power requirements and 'bonus' performance from Ryzen 5000 CPU combos.
 
Do we know if the extra benefits of pairing these with a 5000 CPU are only on x570 motherboards, or also B550 or even the 400 series?

Actually mate, its the total opposite. They only did that for the 6900.

For the 6800 they showed base slide and THEN they showed the performance increase with RAGE and SMART access afterwards.

did we watch the same presentation?
 
Im sure AMD will already be planning a follow up with 5nm GPUs next year. NV might be able to gain the lead again if they make the leap from 12nm to 5nm next year...

AMD will need the 5nm+ process to take on Intel's desktop 10nm CPUs, in 2h 2021.

It's been mentioned a lot so most people obviously were watching a different one.

X570 and B550 only, i think pcie4 is a requirement

Free performance sounds good if you already have or are planning on getting a 5000 Series CPU and X570 or B550 board but I don't think it would be worth the price of upgrading if you have something like B450 and a 3000 series CPU, especially when at higher resolutions.
