By the time rdna3 releases we'll finally able to buy rdna2 cards.
Remember when AMD promised they would have plenty of stock?
Were they underestimating the amount of people wanting to upgrade or was it just talking smack XD
its a smack talk similar to hash rate limiter.
They might have had stock. But even if they did it would go to miners first. Since well it seems chinese have easier time to buy in bulk before the things are even released
I had a hope for a bigger stock for the 6700xt but disappointed
Black colored 6800 XT's doesn't seem like it'll be any different or anything but a new batch of cards with a slightly different color scheme are going up later today on AMD's website.
Red Devil Ultimate
EDIT: I'm not too sure what this is going to do though, might be a tad better but my expectations are fairly mild but this is a thing now, going to be entertaining to see the reviews of it at least.
And the price tag.
Working into the earlier higher clocked less limited Navi2 SKU rumor from before then.
EDIT: And if this is the one GPU with lessened restraints and limits yeah availability on this will be really low even against existing RDNA2 and NVIDIA Ampere stock.
Ampere and it's software suite and drivers or also the GPU performance and certain features or ray tracing might also be a big factor even if this GPU might attempt to take the standard rasterization based performance lead for now.
Well the article also covered testing and with tweaking landed it around 2.6 - 2.7 Ghz so it's not a massive difference over the 6900XT just that it's a bit less silicon lottery here with the higher binned chip.
EDIT: 1.2v GPU core voltage and 330W power draw.
So not too different here a bit more core voltage though over a stock 6900XT (1.175) and a little bit extra wattage. (+30?)
It reminds me of when Polaris had XT(480), XTX(580) and XTR( higher binned 580) released only from few manufacturers. Red Devil Gold was one of them as well as my Aorus XTR.
Wouldn't the XTR be the 590?
No 590 is a polaris30.
TIL - Always thought it was just a 580 with higher power limit.
100mhz clocked higher at 12nm. Its not that much faster than these high binned 580's.
From reading the Reddit the XTXH is a bit confusing you have the GPU itself it's a Red Devil but with a binned chip though it comes with a unique device ID.
Claims on it being higher binned but it's not that much higher clocked and it caps out similar to existing 6800XT's or 6900XT's around 2.6 to 2.7 Ghz.
The changes on the card itself appears to be a modest increase in GPU core voltage over the 6900XT and a slightly higher power draw though the voltage remains locked from More Power Tool modifications or the GPU locks into lower speeds but at least for the better PCB variants 330W power draw could be considered safe allowing the cards to draw a little bit more possibly retaining boost clocks better and under more demanding workloads were it requires additional power thus improving performance somewhat.
The additional changes are from some review driver which is where I assume the device ID and support for this particular card comes into effect with Wattman allowing a higher modifier on it's various sliders although it seems to be only for the GPU core so memory is same as before
Curious if the better binning lends itself well to undervolting and keeping the GPU below hitting any thresholds while still allowing a 2.5 - 2.6 Ghz instead of trying to hit 2.8 or higher looks like that's what the review kinda did landing at 1.175v core voltage but to sustain the clock speeds the card was now on liquid nitrogen so seeing what it can do either on stock air cooling or under water will be interesting once reviews are available for this variant.
AMD selectively changing the limits in the driver is annoying though, that restriction is just a hassle and making additional cards where they can alter these limitations is weird but I suppose since the actual performance difference is 10% - 15% for each step here if you could fully control the GPU and had better limits before it capped or reverted to some fail safe mode it'd be trivial to get the 6800XT to perform at or above the 6900XT levels.
(You already close more than half this average performance difference just with the existing limits, bit more still with More Power Tool.)
EDIT: Expecting the bios to have some restrictions as well otherwise at least all the 6800XT and 6900XT Red Devil GPU users could flash to Ultimate variants to get the higher limits. Same PCB after all with a different device ID but that's just to denote the XTXH variant but that's just the Navi21 chip with some higher binning and since it requires more power and higher voltage it can't be too different from the quality on the 6900XT itself and Navi21XTX chips.
(6900XT for now, would not surprise me if they did a 6800XT version though.)
But it's not really required, a bit more power draw via More Power Tool and just applying this when updating the drivers again is all and the 6800 XT's and 6900 XT's can get close already possibly matching or even exceeding these results.
(The Wattman limits being loosened would be nice for fine tuning the GPU however either for overclocking or better undervolting.)
Eh not too good at explaining and such as usual.
I do wonder however if this might be a thing going forward, if Power Color gets to do a customized variant wouldn't Sapphire want a Nitro++ or XFX something like the Merc319 Pure Black whatever, I don't do marketing terms and names.
Would at least imagine AMD limiting the Merc 319, Nitro (And Toxic) and some other higher-end variants (Plus the original Red Devil.) wasn't too popular and now if they allow Power Color to get a exception I would think the other vendors with these high-end designs would really want in on that too assuming these XTXH binned chips aren't entirely exclusive to Power Color via some deal or agreement between them and AMD.
But even then the regular Navi20 chips could be used in unlocked GPU variants with a slightly higher stock OC, would really like this little artificial limit entirely removed but I wouldn't be entirely surprised if doing it like this especially with current GPU demand and the market situation going on might be what will happen here.
The words 'Launch' and 'Release' normally mean different things but with such poor availability of both NV and AMD cards the release seems meaningless.
