![]() At the very high-end is the $999 Radeon RX 6900 XT. Ray Tracing Overclocked Radeon RX 6800 XT PerformanceĪMD launched the Radeon RX 6000 series of video cards on November 18 th, 2020, also known as Big Navi.4K Overclocked Radeon RX 6800 XT Performance.1440p Overclocked Radeon RX 6800 XT Performance.For now support is enabled on a handful of 500-series chipset-based motherboards, but it will be coming to more in the future. Processors have always had the ability to peek into some portion of GPU memory (a legacy limitation of only 256MB), but Smart Access Memory grants Ryzen 5000 processors full access, which can improve performance with some workloads. SAM allows AMD Ryzen 5000 series processors to access the entire pool of memory attached to a Radeon RX 6000 series GPU over its PCIe 4 interface, when used on a compatible motherboard and chipset. AMD Smart Access Memory, or ASAM, is what AMD is calling its implementation of a feature that is part of the PCIe spec called Resizable BAR. The Radeon RX 6000 series include support for a number of new features as well, namely “AMD Smart Access Memory” and “Rage Mode”. The net effect is a 54% - 65% uplift in performance-per-watt, depending on the particular model GPU tested and about ~2X greater performance (give or take) versus the previous-gen. The new architecture and tuned process, however, have also allowed AMD to boost frequencies by about 30% as well. Before we get down to brass tacks though, let’s take a quick tour of the cards and find out what makes them tick.Ĭombine the benefits of the new architecture, Infinity Cache, along with AMD’s use of optimized libraries for the 7nm process node used to build Big Navi, and the Compute Units in this first wave of RDNA 2-based GPUs end up being approximately 30% more energy efficient than previous-gen offerings. We’ve got the Radeon RX 6800 and Radeon RX 6800 XT in-hand and have a host of data to share with you on the pages ahead (the Radeon RX 6900 XT will be arriving in a few more weeks). ![]() Today, we get to find out how the Radeon RX 6800 series’ performance shakes out on our own. Considering how dominant the GeForce RTX 30 series cards were when they hit the scene, AMD’s claims were intriguing to say the least. And the mighty Radeon RX 6900 XT would go head to head with the powerful GeForce RTX 3090. The Radeon RX 6800 XT would do battle with the GeForce RTX 3080. AMD claimed the Radeon RX 6800 would beat the GeForce RTX 2080 Ti (and by extension the GeForce RTX 3070). The performance numbers AMD showed at its event certainly painted an interesting picture. So, when AMD’s Radeon RX 6000 series was officially unveiled in late October and it is was revealed that the Radeon RX 6800, RX 6800 XT, and flagship Radeon RX 6900 XT would complete directly with the best NVIDIA had to offer, lots of those enthusiasts realized a viable alternative at the high-end of the gaming GPU market on which to spend those dollars might be arriving soon. But, limited availability of GeForce 30-series cards has left a large contingent of enthusiasts in the lurch, with a pile of cash burning a hole in their pockets, itching to upgrade. NVIDIA shook up the GPU market over the last few months with its Ampere-based GeForce RTX 30-series cards, which offer significantly more performance and value than their predecessors. For the past few weeks, PC gamers have been eagerly anticipating the launch of AMD’s Radeon RX 6000 series, a.k.a.
