Gigabyte First To Unveil Radeon RX 6800 Series Reference Variants, $679 & $549 US 16 GB Powerhouses
The Gigabyte Radeon RX 6800 series includes the Navi 21 “Big Navi” GPU based Radeon RX 6800 XT and the Radeon RX 6800. The RDNA 2 powered graphics cards were announced yesterday & offer a superb performance per watt and IPC improvement over the RDNA 1 lineup. The specifications for the graphics cards are mentioned below (via Momomo_US).
Update: Sapphire has also added their reference Radeon RX 6800 series graphics cards on their webpage.
AMD Radeon RX 6800 XT “Big Navi 21 XT” GPU Powered 16 GB Graphics Card
The AMD Radeon RX 6800 XT will come packed with the Navi 21 XT GPU which is a cut-down SKU featuring 72 Compute Units or 4608 SPs. The card will also feature 16 GB of GDDR6 memory across a 256-bit bus interface, a 512 GB/s total bandwidth, and clock speeds of 2015 MHz base and 2250 MHz boost at reference specs. The AMD Radeon RX 6800 XT also packs 72 Ray Accelerators which are dedicated for real-time raytracing workloads. The card will feature a based TBP of 300W with factory overclocked models pushing it above 350W and will arrive at a later date.
In addition to the standard memory, the Radeon RX 6800 series graphics cards will also feature 128 MB of Infinity Cache on the GPU die. The cache will help boost bandwidth for higher performance at resolutions beyond 1080p HD. The 128 MB Infinity Cache boosts the standard 512 GB/s bandwidth by 3.25x, delivering an effective bandwidth of up to 1.664 TB/s across all Big Navi GPU based graphics cards.
