Sapphire Launches the Radeon RX 6900 XT TOXIC Limited Edition

[btarunr]

Sapphire on Thursday (Feb 18) formally launched its flagship graphics card, the TOXIC Radeon RX 6900 XT Limited Edition. This liquid-cooled graphics card features an all-in-one, closed-loop cooling solution that pulls heat from the GPU and memory, while a fan-heatsink cools the VRM and provides some additional air-cooling to the card. The liquid cooler uses a large 360 mm x 120 mm radiator. ARGB illumination covers everything from the radiator fans, to the on-card fan, and the cooler shroud.

The TOXIC Radeon RX 6900 XT Limited Edition features Sapphire's highest factory-overclock for the RX 6900 XT, with engine boost clocks stated to be "beyond" 2365 MHz (vs. 2250 MHz reference). The memory is untouched at 16 Gbps (GDDR6-effective). The card pulls power from a combination of two 8-pin and one 6-pin PCIe power connectors. Display outputs include three DisplayPort 1.4a and an HDMI 2.1. Sapphire is officially pricing the TOXIC Radeon RX 6900 XT Limited Edition at USD $1,499, a 50% premium over the reference design, but you can bet that the real-world pricing could be north of $2,000.

Every 6900 XT is limited edition.

Except if they have a highly binned 6900XT that is garantied to overclocked like crazy, 2000$ would be scary.

 

[thesmokingman]

This thing really needs a real waterblock, just straight waterblock and call it a day. 6900's have terribly poor block support too, shame shame.

50% premium over MSRP of USD 999, does it run 50% faster?

In addition, all these AIO water cooling solution really just cools the GPU. The rest of the components are still sizzling hot, but left to air cooling. Even with a chunky heatsink on the VRAMs and VRMs, I don't think they are that easy to cool.

I am not sure what sorts of crazy overclocking are you looking at. So far all the RX 6900/6800 have a overclocking limit baked into the BIOs. So even if you can get some exotic cooler on it, the RX 6800 caps out at 2.8 Ghz and 6900 @ 3 Ghz? Memory overclocking is also badly limited to 2150Mhz. To me, the memory overclock limit is probably one of the worst thing on the RDNA cards because I feel the card can benefit with a higher memory bandwidth at 4K resolution. This is especially the case in games that may not be optimized to fully utilize the Infinity cache.

I like the regular version more. Less flashy. I guess it all comes down to single LED color or RGB.

sometimes i wonder with something like limited edition, you may keep it for years and re sell it in high price then

That's the whole point, it's not meant to cool the entire computer.

What I was referring to is overclocking in direction of the limit which is 3GHz.
Yes, 6800XT is limited to 2.8GHz and 6900XT to 3.0GHz but very few cards achieve 2.7GHz.
Mine achieves 2650MHz frequency and after that it becomes unstable. I have reference 6800XT which is custom watercooled.
Not all can achieve 2150MHz on VRAM. Mine cannot more than 2100MHz. Set it 2110MHz and run some graphic load and my whole computer hangs requiring reboot.

After following the forums since some time as owner of 6800XT looking at experience from other owners, there is no garantie that cards that have 3×8pin can overclock towards the limit.
So it can happen you have super expensive card and it does not overclock as well as some of reference cards.
What I meant hopefully when they built such a nice watercooled card with 2×8pin and 1x6pin, hopefully they will also select a high binned GPU chip to exploit the potentials.

I agree with you and don't understand why they never do full cover block to cool the other components as well like VRM.
That's why I usually prefer reference card and put it myself under full cover block. The only thing is that it is all up to luck either you get a cards that is good enough and worth the water cooling or it's waste.
Mine definitely worth it as the performance gain from OCing is not that bad. I am getting around 7% higher game performance compared to my own GPU at default setting.
Here are some links to my tuning experiments.

Well, it's a limited edition. There will be few of them, will be well numbered, will have a proof of purchase and maybe in decades will be more valuable. That's what limited editions are for.

There are tons of limited editions of consoles and they perform the same, that doesn't have to do anything with it's performance.

 

[tomc100]

Nobody will be able to buy these cards except for scumbag scalpers with their bots.

LMAO! Best first post of 2021!

I think you missed my point. GPU really means just the GPU chip itself, and not the graphic card.

I like the regular version more. Less flashy. I guess it all comes down to single LED color or RGB.

The VRM temps is really not significantly better than the best air cooler, i.e. TUF. GPU temps are expected to be low considering the AIO is only cooling the GPU, and not the VRAM and VRM. A lot of people may not realize this, but assuming the same air cooler, when the cooler's only role is to cool the GPU, i.e. without cooling the VRAM and VRM, you should expect to see a drastic drop in temp in the region of around 10 degs or more. I've tested this when changing the my stock GTX 1080 Ti cooler to an Arctic Accelero Xtreme IV, the temps dropped from 85 degs under load to around 73 degs. There are reviews out there that proved the same results where it outperforms even the Asus Strix GTX 1080 Ti. While the cooler is huge just a few years back, the main reason why it ran so cool is because its only cooling the GPU chip.

Even if the thermals permit the card to be overclocked further, it will still hit the overclocking hard limit set by AMD.

 

[lightning70]

It looks really nice but I wish it would come out with an exterme air-cooler model.

 

[nguyen]

Actually these exorbitant "Limited" edition are easier to buy than the regular version because scalpers and miners don't touch these.

With the artificial OC limits on gpu's these days I dont really see much of a need for a review anyway, it will preform the same, just be a tad cooler
