MojoKid writes: AMD officially launched its Radeon RX 6800 and Radeon RX 6800 XT graphics cards today, previously known in the PC gaming community as Big Navi. The company claimed these high-end GPUs would compete with NVIDIA’s best GeForce RTX 30 series and it appears AMD made good on its claims. AMD’s new Radeon RX 6800 XT and Radeon 6800 are based on the company’s RDNA 2 GPU architecture, with the former sporting 72 Compute Units (CUs) and 2250MHz boost clock, while the RX 6800 sports 60 CUs at a 2105MHz boost clock. Both cards come equipped with 16GB of GDDR6 memory and 128MB of on-die cache AMD calls Infinity Cache, that improves bandwidth and latency, feeding the GPU in front of its 256-bit GDDR6 memory interface. In the benchmarks, it is fair to say the Radeon RX 6800 is typically faster than an NVIDIA GeForce RTX 3070 just as AMD suggested. Things are not as cut and dry for the Radeon RX 6800 XT though, as the GeForce RTX 3080 and Radeon RX 6800 XT trade victories depending on the game title or workload, but the RTX 3080 has an edge overall. In DXR Ray Tracing performance, NVIDIA has a distinct advantage at the high-end. Though the Radeon RX 6800 wasn’t too far behind and RTX 3070, neither the Radeon RX 6800 XT or 6800 card came close the GeForce RTX 3080. Pricing is set at $649 and $579 for the AMD Radeon RX 6800 XT and Radeon RX 6800, respectively and the cards are on sale as of today. However, demand is likely to be fierce as this new crop of high-end graphics cards from both companies have been quickly evaporating from retail shelves.
