AMD started off October with a bang, announcing the new Ryzen 5000 series CPUs and now to close out the month, we've got official details on three new Radeon RDNA 2 GPUs - RX 6900 XT, RX 6800 XT and RX 6800. All 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. The AMD Radeon RX 6800XT features 72 compute units, 2015Mhz game clock, 2250Mhz boost clock, and 128MB Infinity Cache. It also comes with 16GB of GDDR6 VRAM, and requires 300W total power. This GPU will be priced at $649, and will be available on November 18th. The AMD Radeon RX 6800 features 60 compute units, 1815Mhz game clock, 2105Mhz boost clock, and 128MB Infinity Cache. It also comes with 16GB of GDDR6 VRAM, and requires 250W total power. This GPU will be priced at $579, and will be more powerful than the RTX2080Ti. AMD also revealed its highest RDNA 2 model, the AMD Radeon RX 6900XT. AMD Radeon RX 6900XT will be available on December 8th and will cost $999. This GPU will challenge the RTX3090, a GPU that costs way more than it. The AMD Radeon RX 6900XT features 80 compute units, 2015Mhz game clock, 2250Mhz boost clock, and 128MB Infinity Cache. It also comes with 16GB of GDDR6 VRAM, and requires 300W total power.
