AMD Radeon RX 6800 XT vs AMD Radeon RX 6800

AMD Radeon RX 6800 XT

The AMD Radeon RX 6800 XT is a high-desktop GPU based on the RDNA2 architecture and uses the Navi 21 chip which is manufactured in 7nm at TSMC. The GPU has 4,608 shader units, as well as 16 GB of GDDR6 VRAM with a 256-bit interface (16 Gbps, 512 GB/s).

Features.
RDNA2 serves as the basis for the Navi 21 graphics chip, which is the successor to the Navi 10 graphics chip from the previous RX 5700 series. A number of new features like SAM (Smart Access Memory) and the Infinity Cache make the RX 6800 series very interesting. PCI Express 4.0 and RIS (Radeon Image Sharpening) are still available. The new Media Engine lets you decode video at up to 8K resolution, and the new Display Engine supports screens up to 8K at 60Hz including HDR or 4K HDR at 144Hz. 

Performance.
The performance of the AMD Radeon RX 6800 XT is comparable to a Nvidia GeForce RTX 3080. In the internal duel, the RX 6800 XT clearly surpasses the performance of a Radeon RX 5700 XT. This makes the RX 6800 XT suitable for 4K gaming.

Power consumption

The power consumption of the AMD Radeon RX 6800 XT is quantified by the manufacturer at 300 watts (TGP) and is thus somewhat more economical than the GeForce RTX 3080 (320 watts).

AMD Radeon RX 6800

The AMD Radeon RX 6800 is a high-desktop GPU and is manufactured in the 7nm process at TSMC and based on the RDNA2 architecture. The GPU has 3,840 shader units (60 CUs), as well as 16 GB of GDDR6 VRAM with a 256-bit interface (16 Gbps, 512 GB/s).
