AMD Radeon RX 6900XT to feature Navi 21 XTX GPU with 80 CUs

AMD Radeon RX 6000 series, what we know so far

AMD Radeon RX 6000 series specifications have been known to us since Monday. This week AMD provided a lot of details to AIBs, including new (working) drivers, final SKU names, and so on. We have been able to cross-check parts of the specs and we feel confident that these are more or less final.

AMD Radeon RX 6900 XT – Navi 21 XTX

AMD’s Big Navi will feature 80 Compute Units (5120 Stream Processors). This card will be (for now) AMD exclusive. The Radeon RX 6900XT will be the AMD flagship series, which according to our sources will be in limited quantity. The card would allegedly feature 16GB of GDDR6 memory across a 256-bit bus. The graphics card would feature a 2040 MHz game clock and a 2330 MHz boost clock.

AMD Radeon RX 6800 XT – Navi 21 XT

The cut-down Navi 21 codenamed XT will feature 72 Compute Units (4608 Stream Processors) paired with 16GB of GDDR6 memory. This card will also feature a 256-bit memory bus and clock speed above 2.0 GHz. The game clock is expected to be 2015 MHz and the boost clock should be under 2250 MHz. These are of course AMD reference clocks.

AMD Radeon RX 6800 – Navi 21 XL

The RX 6800 non-X will feature Navi 21 XL variant with 64 Compute Units (4096 Stream Processors). Similarly to 6900XT and 6800XT it will also come with 16GB GDDR6 memory and a 256-bit memory bus. The clock speeds are lower for this part with an 1815 MHz game clock and 2105 MHz boost clock.

The Radeon RX 6900XT, 6800XT, and 6800 will all be unveiled on October 28th.

AMD Radeon RX 6700 XT and 6700 – Navi 22

AMD is also releasing its Radeon RX 6700 series, but not this month. The RX 6700 series will feature Navi 22 GPU. According to our sources, AMD has recently decided to launch these GPUs quicker than previously planned. The current plan is to launch them in January. The Radeon RX 6700XT is expected to be full Navi 22 with 40 CUs (2560 Stream Processors). The RX 6700 XT Navi 22 graphics card is said to feature 12GB GDDR6 192-bit memory.

A few more things

Although we had the specs since Monday, another news outlet has been the first to publish the correct SKU/configurations before us. The information posted earlier today by Coreteks is more or less the same with some small changes to the clock speeds. We are however expanding this information with RX 6700 SKUs.

We will talk more about performance and special cache built into the Big Navi later (we are still collecting information). We can confirm also that AIBs will release their custom cards next month, but the priority is on AMD reference design. According to our information, the MBA (reference) cards will even have a separate review embargo.
