As the date of the announcement of the Radeon RX 6000 (Navi 2X) graphics cards with the 2nd generation RDNA architecture approaches, the flow of information about the main hope of all supporters of the “red” camp is growing. Just yesterday, we learned about the power consumption of the new generation of Radeon cards, and today the videoCardz profile web resource revealed the key characteristics of the GPU Navi 21, which will serve as the basis for at least three video cards of the Radeon RX 6000 series.

Building on previous leaks, at the start, the line of Radeon RX 6000 graphics cards will be represented by three adapters – Radeon RX 6900 XT, RX 6800 XT and RX 6800. All have the same basis – 7nm Navi 21 GPU, but in different configurations (XTX, XT and XL).

As anticipated, the company will continue to use the GPU architecture in its RDNA 2 architecture, in which a single CU contains 64 SP stream processors. This scheme has been in use since the first generation Graphics Core Next architecture.

The full version of the GPU Navi 21 XTX, which will be used in the flagship Radeon RX 6900 XT (aka Big Navi), will receive 80 compute units or 5120 stream processors. GPU frequency – from 2040 to 2330 MHz. The card will be a temporary AMD exclusive. That is, modifications from OEM partners will not appear soon. Also, the source warns about the limited availability of this model.

A notch below is a stripped-down version of the Navi 21 XT (RX 6800 XT) with 72 CUs (4608 stream processors) and a frequency from 2015 to 2250 MHz. Even lower is a more stripped-down version of Navi 21 XL (RX 6800): 64 CUs, which corresponds to 4096 stream processors, and frequencies from 1815 to 2150 MHz.

All three Radeon RX 6000 cards will receive 16 GB of GDDR6 video memory with a 256-bit bus, complemented by special caching technology Infinity Cachewhich should ensure parity in memory bandwidth with competing RTX 3080/3090 models using faster GDDR6X memory.

Also in the latest report, the RX 6700 XT and Radeon RX 6700 based on Navi 22 GPU appear. Their announcement is expected in January 2021. So far, only the characteristics of the older model RX 6700 XT are known: 40 CUs (2560 stream processors), 12 GB GDDR6 and a 192-bit bus.

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