In this review, we put the Radeon RX 6800 XT through its paces to test all of AMD's performance claims to tell you if AMD is back in the high-end game. AMD is marketing the RX 6800 XT as the card to buy for maxed out gaming at 4K Ultra HD resolution-the same use case the RTX 3080 is meant for. AMD is offering the Radeon RX 6800 XT at $649, or $50 less than the RTX 3080. The reference AMD RX 6800 XT features a boost clock of 2,250MHz, whereas the Sapphire Nitro+ bumps it up to an impressive 2,360MHz. Shouldn't that starve the silicon of memory bandwidth? AMD could have sought out broader memory buses, or even taken the HBM-MCM route, which would have hit the company's price-cutting headroom against NVIDIA, but the company changed tactics by introducing a clever new component called Infinity Cache, which we'll talk more about in the Architecture section. AMD also doubled the memory amount to 16 GB, although the memory bus is still 256-bit, and the company is using JEDEC-standard 16 Gbps GDDR6 (512 GB/s). Each of these RDNA2 compute units has raytracing hardware. The Radeon RX 6800 XT, along with the RX 6800, is based on the 7 nm "Navi 21" RDNA2 silicon with an 80% increase in compute units over the RX 5700 XT. Under the exoskeleton, a thick heatsink keeps thermals under tight control. An all-metal shroud houses three powerful axial-tech fans with dual ball fan bearings and extra blades. Get breathtaking gaming experiences with powerful new compute. We would have called BS on these straightaway if AMD hadn't priced these cards well upwards of $500-AMD is confident about the performance of these cards being enough for such a heavy price tag in NVIDIA's league. The TUF GAMING Radeon RX 6800 XT is a tenacious beast with a tough metal exterior, super-efficient cooling, and components that offer enhanced endurance. AMD Radeon RX 6800 Series graphics cards deliver ultra-high frame rates and serious 4K visuals. The flagship RX 6900 XT is purported to compete with the RTX 3090-it will launch later this year. AORUS Radeon RX 6800 XT MASTER Graphics Card comes with 16G GDDR6, Dual BIOS. The Radeon RX 6800 XT in this review was being compared to the RTX 3080, and the RX 6800 ( also being reviewed today) to the RTX 2080 Ti, which is essentially the RTX 3070. What was unraveled in that stream was jaw-dropping, with AMD claiming its RX 6000 series chips to go up against NVIDIA's fastest, and being competitively priced as well. When we started watching AMD's live-stream announcement for the new RX 6000 series in late October, after having reviewed the RTX 3080, little did we expect AMD to launch a "high-end" GPU. NVIDIA more than doubled the shader counts of its GeForce "Ampere" GPUs over the previous generation since it sought to make "RTX on" frame rates roughly match the "RTX off" frame rates of "Turing." Since this is AMD's first Radeon to feature real-time raytracing, a doubling of the shader count for "Big Navi" over the RX 5700 was also expected, and double them AMD did.
