Who knows. Maybe never if M$ and Sony have a say. Lisa Su said the 6800 would be out before the consoles so where are they? Missing in action maybe?

yes NV is doing so well on the 3000's that new in the box 2080 ti Strix cards are now selling on ebay for 600 to 1000+ over MSRP

https://www.ebay.com/sch/i.html?_fro...Condition=1000


another month or two of NV doing this well and i will be able to sell my used 2080 ti strix and 1080 ti strix for more than i paid for them new

So you're calling me anti AMD. Really. So you own an AMD 580 and an Intel CPU OK. So I'm anti AMD and you're what? An MD fanboi? AMD is not your mother/father/brother/sister it's a corporate entity that has no persona that doesn't know who you are and doesn't like or dislike you. Get over it it's the same as Nvidia it's a company owned by shareholders who want to make profits so they can pay dividends. It's not a divine body

Take off the tinted glasses and see the world as it really is.

I said 'people like you'. You are a whiner and a complainer and you lack patience. You are a downer and a severe sapper of forum energy.

Please get a card soon.

The jacket is pi**ing his pants laughing at this debacle. Amazing how AMD have got so many things wrong TBH. After Nvidia's launch issues they had a massive advantage and fuc8ed it up. Sad.

Is AMD screwing them? Or is it possible with all the effects of the pandemic, and other factors, that it actually cost more to produce the 6000 series chips. Remember, Nvidia chose samsung because they did not want to pay tmsc's prices. It's possible that AMD is selling their reference cards at cost, or barely above making little profit themselves.

Now, they could be "screwing them" but right now itis just an assumption, or speculation without anything backing it, as people (hardware unboxed) has no idea what AMD's margins are, and neither do we.

Patience folks. Good things come to those who wait.

If you got a card that can do 1440p at somewhat reduced settings.. live with it till they get some stock built up.

I waited and it got me a $525 BNIB Vega 64 Liquid at a Best Buy closing special during the mining boom. Still running it to this day and it serves my needs 100%.

And to the owner of the VII.. Tempting. I don't need it, as all it'd be doing is [email protected] most likely.

I’m sorry, but you should be banned......for two weeks!

This is funny .... the prices for Radeon VII..Why they are inflated ?

Because they be limited. Maybe I should hold on to mine and see where this goes

Would they need Infinity Cache if they went HBM2(3?).

I see that MI100 uses HBM2 (32GB) @ 1.2GHz. With that clock they have app. 1228.8GB/s.

Infinity cache, as presented in RDNA2 is 2.17x "faster" than GDDR6 256b which gives it a bandwith of 1111.04GB/s.

If I recall correctly, Radeon VII actually is quite powerful for some productivity tasks, which is why it fetches a high price even though its gaming performance is only second tier. If you're someone who can use the card for work, then it also doubles as more or less 1080 Ti performance in gaming.

depends. I would argue a large cache is always useful to some degree especially if an architecture is designed around its use.

IIRC, The (Vega 20) VII's aren't neutered when comes to fp64, ie half speed, and rather profitable when comes to mining hash rate.

This is the most ridiculous dick swinging contest in a GPU thread I've ever seen, but par the course for r3d I guess.. jeez

[Trunks0]

Little bit of thread clean up to keep things on-topic. Hilarious read, but where getting a little tooooo derailed. No warnings being issued, no foul play, all in good fun. Just trying to keep the thread on-topic

Yep, anything where groups of threads are going to be hitting the same data/same data locality is going to benefit from a bigger cache, and that covers a lot of GPU work.

Ray Tracing is the only potential wrinkle in that plan, as while the first rays are nice and coherent, secondary rays can shoot off in all kinds of direction. Cache would help with keeping the data structure around and close to the cores, but might not help as much with sampling things (unless you can bundle the rays together somehow).

Spot on. I don't think infinity cache is going anywhere anytime soon. Majority of the performance improvement and power efficiency seems to be attributed to the infinity cache. I'm starting to think the 6900XT has 256mb of Infinity because it has an even higher performance per watt advantage.

AMD's site is listing the 6900XT as having 128Meg, I suspect this is because the 6900XT is the same die as the 6800(XT) but with higher binning/no CU issues so everything is active.

However, I wouldn't be surprised to see RDNA3 chips with 256meg (or maybe more; they might ratio it somehow with memory bandwidth or some CU requirement) when they appear.

So that could imply the possibility of flashing 6800 xt -> 6900 xt? Just as some speculates going from 6800 -> 6800 xt.

Unless everything is "lasercut".

Well damn, es lag direkt vorm Gesicht.

I think they will ratio RDNA3's Infinity pool with the number chiplets.

I wouldn't count on it - the specs, CU counts and related hardware aside, looks identical between the two boards/chips, so unless they are getting far more yield of fully working chips than they expected and they aren't expecting much demand for the 6900xt, I would be surprised if the 6800xt could be made to enable those extra 8 CU/4 WGP on the chip.

Did anyone break 3 Gs on this thing?

[Mangler]

There might be a clock limit of 2.8ghz right now.

Apparently the 6900XT has a GPU clock of 3GHz. That's impressive if true.

next time their going to try to get both the CPU's and GPU's at 5+ GHz


i didn't think it would be AMD that would be the first to break 3 GHz on a GPU first

.......

and i think it is max GPU clock in bios is 3 GHz not that all will hit that but some may on water

Thats the bios upper limit. Its 2.8 ghz on the 6800xt.

Wow man I thought the powercolor would be the top card but XFX has a really good cooler as well. Its not just the OC its the temps:



2.7 ghz with 70c hot spot temps? Damn... And it maintains those clocks. I think we know where this is going with the 6900xt. I really hope the Dec big driver release gives a good perf boost for 4k along with something extra for RT. And maybe jump the gddr6 from 16 to 18 gbps at least on the aibs I hope.

and a full water 6900 xt card hitting 3000 ghz

9 days of leaks maybe

We knew TSMC silicon was tops but this is insane. Its on the *same* 7nm node as the 5700xt BUT! Its a chip 3x the size with an extra full fat GHZ while running COOLER.

The mind boggles.

You can say it's 7nm+

Looks like 6700xt will have same high clocks:

In a most recent article from Igor Wallossek we learn about the Radeon RX 6700 XT designs from AMD board partners. The detailed information on power and frequency limits has now been confirmed. While Igor does not name the manufacturers whose BIOSes are being shown, there is no doubt that this is real. Igor had previously posted very similar information in regard to the RX 6800 series, which later turned out to be true.

The BIOS information reveals that the maximum GPU frequency that can be set through Radeon Software is 2950 MHz. Yesterday we reported that Radeon RX 6900XT has a maximum GPU clock of 3000 MHz, which is higher than RX 6800 XT’s 2800 MHz. That said, the RX 6700XT maximum GFX clock would sit in between Navi 21 XT and Navi 21 XTX. This particular RX 6700 XT board partner card has a maximum GFX clock of 2854 MHz, which is indeed higher than most Navi 21 designs:
