This means the majority of ray tracing games that work on Nvidia RTX – such as Shadow of the Tomb Raider, Fortnite and Watchdogs Legion – are compatible with RX 6000 graphics cards. The good news is that AMD will support all ray tracing titles that use industry-based standards. It also needs to be manually added to a game by developers, which is a key reason that there are only a select number of titles that support the tech at the moment. The only downside is that ray tracing puts a serious performance drain on a GPU, and can half frame rate counts in some titles. Allowing for real-time rendering of reflections in mirrors or liquids, for example, the tech has proved impressive in the early games we’ve tested, making titles look significantly more realistic. Ray tracing is a graphics technology that aims to let graphics cards more realistically render light, shadows and reflections. This is an incremental step for AMD and the first time any of its cards have supported DirectX Ultimate-level ray tracing. However, the specs aren’t the most interesting bit about the RX line. GPUĪll information in this table is based on the firms’ first-party cards. You can see how the RX 6800 compares to its siblings and the Nvidia competition on core specs below. However, considering the fact it’s yet to appear on the 3070 Nvidia card, this isn’t a deal breaker for the RX 6800. Nvidia’s latest RTX 3080 and RTX 3090 cards made the jump to GDDR6x which offers greater bandwidth, but is more expensive. The only spec some gamers may sniff at is its use of 16GB of GDDR6 RAM. This means it beats its main rival in this regard, although given the architectural differences between Ampere and RDNA 2 and how they handle different workloads, that isn’t the best metric to judge overall performance. When it comes to raw specs it stacks up against the competition fairly well, coming with 60 compute units and a reasonable 1815MHz game frequency. Like most of 2020’s graphics cards, it’s more demanding than older units, with AMD recommending you power it with a 650W PSU minimum. The card has a triple-fan design that makes it marginally larger than the RTX 3070, but it uses a basic 2x 8-pin PCIe connection instead of the custom pin system seen in Nvidia’s new cards, so there’s no need to worry about an adapter. This means most of the improvements are a result of developments to the card’s architecture, not the manufacturing process. The AMD Radeon RX 6800 is built on a 7nm manufacturing process, as was the case with last year’s 5000 cards. RDNA 2 architecture provides a performance boost.The only downside is that, with AMD yet to have an answer to DLSS, ray tracing frame rates are occasionally an issue. Make no mistake, the RX 6800 is a fantastic GPU and the perfect choice for any gamer looking to make the jump to 4K. However, having thoroughly put the RX 6800 through its paces, we can confirm AMD has well and truly put its money where its mouth is. But, with AMD having oversold its graphics cards performance more than once in the past, you may justifiably be taking these claims with a pinch of salt. With AMD quoting the card as offering “ RTX 2080Ti / 3070” level performance, this makes it a seriously enticing prospect for any gamer looking to make the jump to 4K – especially considering the lack of 3070 stock at the moment. This makes it one of the first AMD cards to support ray tracing, a key feature that radically improves the presentation of light and reflections in games that had previously been limited to Nvidia’s line of RTX graphics cards. If that sounds familiar, it should – the PS5, Xbox Series X and Xbox Series S’ custom GPUs are all built using the same tech. The RX 6800 is currently the cheapest card on the market that’s built on AMD’s new RDNA 2 architecture. The Radeon RX 6800 is AMD’s answer to Nvidia’s outstanding GeForce RTX 3070 graphics card, which is one of only a few tech pieces to achieve Trusted Reviews’ hallowed 5/5 rating.
