GPU AMD Navi 21 XT (Radeon RX 6900 XT) can overclock up to 2.4 GHz in Game Clock

Recently, the network has been filled with various rumors and leaks about Radeon RX 6000 (Navi 2X) graphics cards with 2nd generation RDNA architecture, which will debut next week. A new and rather interesting piece of information concerns the flagship GPU Navi 21 (Sienna Cichlid), confirming earlier reports of record high operating frequencies.

The latest data indicate that the Navi 21 GPU will be the mainstay of at least three Radeon RX 6000 series graphics cards. The Navi 21 GPU XT variant will be used in the flagship Radeon RX 6900 XT, codenamed Big Navi. Along with Navi 21 XT, there is also a selected exclusive version of Navi 21 XTX, intended for a potential Radeon RX 6900 XT Limited Edition (analogue of the Radeon RX 5700 XT 50th Anniversary for the upper segment), as well as a stripped-down version of the Navi 21 XL.

All three cards based on GPU Navi 21 will receive 16GB of GDDR6 video memory with a 256-bit bus, complemented by special caching technology Infinity Cache, which should provide memory bandwidth parity with competing RTX 3080/3090 models using faster memory GDDR6X.

New data indicates that the base Navi 21 XT GPU in AMD’s non-reference AIB cards will be able to overclock to an impressive 2.4GHz in Game Clock mode, which no other GPU on the market can boast of such a high operating frequency today. The TGP (total graphics power) is expected to be 255 watts. That is, the TBP (total board power) value should be at the level of the GeForce RTX 3080 (~ 320 W). At the same time, the peak frequency of the GPU Radeon RX 6900 XT in the reference version will be limited to 2300 MHz.

It is not yet clear what these impressive operating frequencies will mean in practice. Judging by the official performance tests of the Radeon RX 6900 XT, which AMD shared during the recent Ryzen 5000 announcement, the new flagship of the “red” will definitely be faster than the RTX 3070, but will it be able to compete with the RTX 3080? This question remains unanswered so far.

The full announcement of the RX 6000 series of graphics cards, which will compete with the latest NVIDIA GeForce RTX 30 series adapters, will take place on October 28.
