Vega cards were literally called Vega 56 & Vega 64.

RX 6800 are Big Navi.

You're still overestimating the amount of effort I'm prepared to put into remembering this stuff.

Saying "New AMD GPUs" may be better so, just to avoid confusion

I'm reading that the 16GB of VRAM is 'too big' and realistically can't load textures in and out quick enough to be truly useful. Admittedly this was on the nVidia subreddit... :pac:

Any thoughts? Is 16GB of GDDR6 just a gimmick?

Sounds like a load of horse shíte. 6X can in theory process textures faster, but no developers are using it as their benchmark at the moment, and likely won't be until it becomes a standard when GDDR6 and old cards are phased out.

yesterday saw that 'rumour' on AMD use 80% of their 7nm wafers on consoles - thats why the supply is f*cked in Q4 this year (AMD already knew this since the beginning). I thought it makes sense, consoles chips save their bankruptcy back so they have to deliver that.

Have to say the 6800xt fromm XFX is pure TECH PORN.

No, not a gimmick at all. There is virtually no penalty for having better textures, provided that they fit into vram. If GPU needs to reach out to system RAM to get textures, that ruins the performance.

That makes perfect sense. I said that before - AMD has contractual obligations towards MS and Sony. AMD wants to maintain good relationship with them as well. From what's left, they would rather make 7x more Zen chiplets than RDNA2 cores.

Is this because they are using 16 GB of GDDR6 instead for GDDR6x?

Is the 3090 suffering from the same performance hit or its totally different architecture.

Another problem with drivers? Pairing Amd gpu and cpu lowers average fps.

Nvidia was selling it's video cards to crypto miners
I hope and was not doing the same
If so you may not get cards until end March according to a few websites

AMD drivers, always need a couple of versions to reach a good state.

However, unlike Nvidia, they always give boost to the cards, even older models.

Been saying it for a while as well. TSMC's 7nm fabs were maxed out from various big contracts. Console being only a small part of that for them but a big part of AMD's orders. They pre made 10 million PS5's APU's, I think Microsoft only had about 2 million Xbox's from what I've read. They also had next gen Ryzen cpu's to make.

It should all calm down after Christmas with AMD saying there will be a lot more supply in 1-2 months with some third party cards available near MSRP.

Nvidia had to go with Samsungs inferior 8nm node making the gpu dies bigger and less power efficient than Samsungs 7nm. The 3080 and 3090 do see better gains going to 4k than the 3070, which uses standard ddr6 as well, which hints that the gddr6x does make a difference at that resolution.

Not that much... The main advantage comes from the 384bit and 320bit buses for 3090 and 3080 respectively, against 256bit for the 3070. Same reason 6800XT falls behind in 4K

BloodBath

The speeds are closer than I thought. I had read gddr6 maxes around 16gb/s but it's actually running closer to 19.2gb/s on the 6800xt which is around the same as Nvidias gddr6x so yeah it's practically all the bus width then.

Did Nvidia only go with gdd6x for the power savings then? That big Samsung die is power hungry.

The other thing about VRAM is that it depends on how any given game engine deals with the textures; how does it store the textures, how does it deal with first load/recall requests, is compression/decompression involved, etc etc. Engine A might be really good at the load/recall process, which might make one think it would mitigate the difference in VRAM size, whereas another engine might excel at identifying which textures are best kept in memory which might actually be more efficient. That's why gaming is in many ways a meaningless benchmark because you never actually know what's going on under the hood, or whether what's going on under the hood is **** (Crysis).

Hurry and get your $1,699 RX 6800 XT

In fairness, its a scammer. Newegg have tried to be amazon, but failed badly at doing the reseller thing.

Is that your Twitter profile? Your name is showing on the top right if it is.

Also just under the name you can clearly see the item is sold by "Creator" so Newegg aren't scalping.

My RX6800 was delivered by Fastway this morning and signed for by me. Except it wasn't, and receptionist knows nothing about it either. Call to Fastway got nowhere. Seriously hope it turns up tomorrow.

It's me. And it's their website, not anyone can go on there and make a listing. Very much their burden of liability, and brand relations.

Fingers crossed it turns up buddy

That's happening very often with deliveries in general. We have it with a lot of our orders due to Covid. Most of the time the delivery driver didn't get time to deliver it on his run and will sign your name and try again the next day.

Typical Fastway. Deliver it, dump it in garden.

Yeah but usually the garden they dump it in is about 20 miles away from where it should be...i hate fastway..i steer well away from any site using them as delivery.

Rumours floating around this morning that AMD have had talks with AIB partners to ensure their cards are sold at MSRP and we should expect a influx of those MSRP cards within 8 weeks

I didn't realise they would be the courier, if I had I would not have used them.

They are unbelievable, they literally leave parcels on doorsteps all the time.

For all I know they left my RX6800 on my doorstep at 7am and it was stolen.

I mean what happens in that case, it says I signed for the ****ing thing, I'm sure AMD will look at it and go "you signed for it"...how are they supposed to know that's not my signature?
