New AMD RX 6800 vs 6900XT RDNA2 Based Benchmarks Comparison | New AMD Graphic card performance
11All three GPUs are based on AMD’s new RDNA 2 architecture, delivering up to 65% more performance per watt compared to the original RDNA 1 architecture while using the same 7nm process. AMD has also been able to squeeze out an additional 30 percent in average clock speeds.
Another interesting feature is Infinity Cache, which allows for more bandwidth while keeping power consumption down. This is a particularly big benefit for 4K gaming, where large amounts of data needs to move through the GPU memory.
In the images above, you’ll see some of the gains expected from RDNA 2 GPUs, as well as comparisons to RDNA 1 and Nvidia’s RTX 3080. Compared to the RX 5700, an RDNA 2 GPU can offer up to 2.2x more performance at 4K. Moving down to 1440p, the RX 6800 XT is shown trading blows with the Nvidia RTX 3080 while using 20W less power.
If you pair an RX 6000 series GPU with a Ryzen 5000 series CPU and a 500-series motherboard, then you’ll get access to more performance. AMD has implemented a new feature called AMD Smart Access Memory, which provides full access to GPU memory between a Ryzen 5000 series CPU and an RDNA 2-based GPU. This in turn provides a performance uplift, one that grows when you activate ‘Rage Mode’, AMD’s new one-click overclocking tool for CPU and GPU.
