All You Need To Know About AMD RX 6000 Series and Big Navi

AMD Big Navi GPUs are promising big performance and efficiency gains, along with a driver update. Will Team Red finally take the pole position in our GPU hierarchy and claim the crown for the best Graphics Card? It’s hard to say with NVIDIA RTX 3090,3080 and 3070 now revealed.

Big Navi at a Glance

• Up to 80 CUs / 5120 shaders
• 50% better performance per watt
• Coming October 28
• Pricing of $549-$599 for RX 6900 XT

Other Info About Big Navi:

• Big Navi / RDNA 2 has to add support for ray tracing and some other tech, which should require quite a few transistors. AMD may also go with very large caches, which would help overcome potential bandwidth limitations caused by the somewhat narrow 256-bit and 192-bit bus widths. Note that Nvidia has opted for a 320-bit bus on the 3080 and 384-bit on the 3090, plus faster GDDR6X memory.

• The top model will almost certainly be called RX 6900 XT, with the various performance tiers as RX 6800 XT, 6700 XT, etc. It also looks like AMD is moving into higher performance segments, going by the 6900 and 6800 model numbers, with the 5600 XT replacement ending up as the 6700 XT. The 5500 XT meanwhile will eventually be replaced by 6500 XT is our assumption, so there’s a 200 point gap between the high-end 6700 and the mainstream/budget 6500.
• PS5 and XBOX SERIES X will have the new generation AMD RX 6000 series GPU

AMD could potentially launch the RX 6000 GPUs at that time, but more likely is that it will first reveal the architecture, specs, and other details similar to what Nvidia did with it’s Ampere announcement. That means actual GPUs will probably arrive in November, just in time for the holiday shoppers.
