"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."
