This is our review of the AMD RX 6800 XT video card, looking at RDNA2 and the reference cooler vs. the RTX 3080, 3090, 3070, RX 5700 XT, & more. Includes Smart Access Memory tests.

As a reminder, the RX 6800 XT competes directly with the NVIDIA GeForce RTX 3080 cards (theoretically at $650 for the XT vs. $700 MSRP for the 3080). The RX 6800 non-XT competes with the RTX 3070 (with the 3070 running theoretically cheaper). Our review of the AMD RX 6800 XT looking at thermal design, cooling, noise levels, gaming performance, Smart Access Memory on vs. off performance, AMD Ryzen vs. Intel performance, ray tracing (RTX/DXR) benchmarks vs. NVIDIA, RDNA2 overclocking behaviors, and more. This is one of the densest-packed reviews we've published lately, and we barely finished it before embargo lift. More to come in short order. Our pressure testing and flatness testing will be pushed into a secondary piece focusing entirely on thermals, as this review ran long enough as is. PCIe 4 vs. PCIe 3 doesn't make much impact on performance, as we showed previously with the RTX 3080, and so any AMD vs. Intel CPU differences are primarily resultant of the higher performance of AMD (particularly at 1080p). Our benchmarks include 4K, 1440p (2560x1440), and 1080p for the RX 6800 XT vs. RTX 3080, et al. Smart Access Memory testing includes the requisite Ryzen 5000 (5900X) CPU, X570 board, and RX 6000 GPU. NVIDIA is working on its own competing feature, but they didn't launch it in time for this review.
