The Radeon PRO W6400 is a professional graphics card by AMD, launched on January 19th, 2022. Built on the 6 nm process, and based on the Navi 24 graphics processor, in its Navi 24 XL-W variant, the card supports DirectX 12 Ultimate. The Navi 24 graphics processor is an average sized chip with a die area of 107 mm² and 5,400 million transistors. Unlike the fully unlocked Radeon RX 6500 XT, which uses the same GPU but has all 1024 shaders enabled, AMD has disabled some shading units on the Radeon PRO W6400 to reach the product's target shader count. It features 768 shading units, 48 texture mapping units, and 32 ROPs. The card also has 12 raytracing acceleration cores. AMD has paired 4 GB GDDR6 memory with the Radeon PRO W6400, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 2039 MHz, which can be boosted up to 2321 MHz, memory is running at 2000 MHz (16 Gbps effective).
Being a single-slot card, the AMD Radeon PRO W6400 does not require any additional power connector, its power draw is rated at 50 W maximum. Display outputs include: 2x DisplayPort 1.4a. Radeon PRO W6400 is connected to the rest of the system using a PCI-Express 4.0 x4 interface.
