AMD RX 6800 XT: Specification | Hashrate

Internal structure (characteristics)

After several years of using the Graphics Core Next (GCN) architecture, AMD introduced the RDNA architecture in July 2019, with the RX 5700 and RX 5700 XT becoming the first cards to use this new technology and 7nm process technology.

AMD is positioning the RX 6800 XT as the main competitor to the Nvidia RTX 3080

Average price of RX 6800 XT in Europe is ~ $ 649 ( NOT in Russia!). It turns out that the card will not sell much cheaper than its competitor, the RTX 3080 ($ 700).

The RX 6800 XT is still TSMC’s 7nm process, just like the RX 5000 series, the Navi 21 has a much larger 519mm² GPU.

The RX 6800 XT contains 72 Compute Units (CU) with 64 stream processors for a total of 4608 shaders.

The clock speed of the RX 6000 series graphics cards has increased significantly:

• Game Clock – 2015 MHz
• Boost Clock – 2250 MHz

For comparison: Game Clock RX 5700 XT – 1755 MHz.

AMD has also increased the memory capacity by installing 16GB of GDDR6 memory in each RX 6000 model (however, lower-end models are likely to get less memory).

The memory is clocked at 16 Gbps and operates over a 256-bit memory interface with a total bandwidth of 512 GB / s.

AMD has also implemented 128MB Infinity Cache on the Navi 21 GPU to dramatically increase effective memory bandwidth without excessive power consumption.

In terms of power consumption, the RX 6800 XT has a rated total power (TBP) of 300W , which is 75W more than the RX 5700 XT.
