AMD Radeon RX 6950 XT

AMD Radeon RX 6950 XT

The AMD Radeon RX 6950 XT is a high-end desktop GPU based on the RDNA2 architecture and uses the Navi 21 chip which is manufactured in 7nm at TSMC. The GPU has 80 compute units (CUs) / 5,120 shader units, as well as 16 GB of GDDR6 VRAM with a 256-bit interface (16 Gbps, 512 GB/s). The GPU supports hardware accelerated raytracing thanks to the RDNA2 architecture. Compared to the RX 6900 XT, the 6950 XT offers higher GPU clock speeds.

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 6950 XT is between a Nvidia GeForce RTX 3090 and a RTX 3090 Ti. Therefore, the RX 6950XT is one of the fastest desktop cards in 2021 and well suited for 4K gaming. 

Power consumption

The power consumption of the AMD Radeon RX 6950 XT is specified by the manufacturer at 335 Watts (TGP) and is thus somewhat less power-hungry than the GeForce RTX 3090 (350 Watts).
