AMD has recently launched its Radeon "Big Navi" 6000 series of graphics cards, making entry to the high-end market and positioning itself well against the competition. The "Big Navi" graphics cards are based on Navi 21 XL (Radeon RX 6800), Navi 21 XT (Radeon RX 6800 XT), and Navi 21 XTX (Radeon RX 6900 XT) GPU revision, each of which features a different number of Shaders/TMUs/ROPs. The highest-end Navi 21 XTX is the highest performance revision featuring 80 Compute Units with 5120 cores. However, it seems like AMD is preparing another similar silicon called Navi 21 XTXH. Currently, it is unknown what the additional "H" means. It could indicate an upgraded version with more CUs, or perhaps a bit cut down configuration. It is unclear where such a GPU would fit in the lineup or is it just an engineering sample that is never making it to the market. It could represent a potential response from AMD to NVIDIA's upcoming GeForce RTX 3080 Ti graphics card, however, that is just speculation. Other options suggest that such a GPU would be a part of mainstream notebook lineup, just like Renoir comes in the "H" variant. We have to wait and see what AMD does to find out more.

A version with GDDR6X memory instead of 6?

Pretty sure Micron and Nvidia teamed up for GDDR6X. Not sure if it's open to others.

Mm, for me, only H stood out.
Perhaps because 6800 XTX => 6900 XT.

I wonder what H stands for. "Ha ha" perhaps?

It could represent a potential response from AMD to NVIDIA's upcoming GeForce RTX 3080 Ti
6900 XT beats 50% more expensive 3090 in a number of games.
In fact, it wins 5 to 2 against 3090 in most new/actual games

3070's sell for $700+ (the cheapest I could find in Germany is 729 Euro)

Why would AMD need anything to counter 3080Ti???

XTX is a standard classification for the high-end graphics cards.

The "H" is probably just pointing to a high-performance mobile part, like, I dunno... their CPUs?!

So XTXH is a mobile high-performance part, which makes sense, since the screen grab says "27W".

I think some basic knowledge of AMD naming would've come in handy, here.

If you stretch this a bit, and considering the hybrid naming XTXH, it could mean some APU, but I'm thinking it's just a notebook system with CPU and Radeon GPU.

I remember the XTX models back in the day... AMD come on, give us a 3090 killer :D Maybe its something to combat the 3080 Ti? Then the 6900 XT can drop a little in price?? We can but dream I guess :)

I've been dreaming of a nice new gpu for a while now...:sleep:
Myself included, been after a 3080 Tuf when I heard how much extra the 3090 was going to be... I'm happy to hold on for a little longer now and see what AMD are going to do with this XTX model... It'll be a shame if it's mobile but meh, not going to matter so much :)

Those infinity fabric interconnects can save a lot of power, if you let it buffer the communication. They are not simple copper interconnects which have fixed power consumption.

Bringing another variant when there isn't near enough inventory to supply current demand. Seems smart. Also come out with the XTX Bot Proof edition.

Either HBM version or The full fat CU with 7300+ core version ? Hope so... good that scalpers emptied all that stock that stopped me from making the move on a new GPU... Great news

The H does not stand for Mobile when it comes to AMD.. Their mobile lineup always has a M prefix when it comes to the GPU, so this could be an HBM 2.0 card.

Make sense but I doubt that HBM2e will coming to consumer product.

Benchmark Scores I once clocked a Celeron-300A to 564MHz on an Abit BE6 and it scored over 9000.
It might be a reference liquid cooled version with higher clock limits for better oc.

Hydro is likely, IMO.

The other option could be HBM for a datacenter/workstation card - I'm honestly not sure if RDNA2 memory controllers and caches were designed/compatible with HBM though.

I have yet to find a current gen AMD offerings in both CPU and GPU segments available to order at rated prices or close to it. It is just been a paper launch year. From all companies. Very disappointed.
