The Radeon RX 6600 is a performance-segment graphics card by AMD, launched on October 13th, 2021. Built on the 7 nm process, and based on the Navi 23 graphics processor, in its Navi 23 XL variant, the card supports DirectX 12 Ultimate. This ensures that all modern games will run on Radeon RX 6600. Additionally, the DirectX 12 Ultimate capability guarantees support for hardware-raytracing, variable-rate shading and more, in upcoming video games. The Navi 23 graphics processor is an average sized chip with a die area of 237 mm² and 11,060 million transistors. Unlike the fully unlocked Radeon RX 6600 XT, which uses the same GPU but has all 2048 shaders enabled, AMD has disabled some shading units on the Radeon RX 6600 to reach the product's target shader count. It features 1792 shading units, 112 texture mapping units, and 64 ROPs. The card also has 28 raytracing acceleration cores. AMD has paired 8 GB GDDR6 memory with the Radeon RX 6600, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 1626 MHz, which can be boosted up to 2491 MHz, memory is running at 1750 MHz (14 Gbps effective).
Being a dual-slot card, the AMD Radeon RX 6600 draws power from 1x 8-pin power connector, with power draw rated at 132 W maximum. Display outputs include: 1x HDMI 2.1, 3x DisplayPort 1.4a. Radeon RX 6600 is connected to the rest of the system using a PCI-Express 4.0 x8 interface. The card's dimensions are 190 mm x 110 mm x 40 mm, and it features a dual-slot cooling solution. Its price at launch was 329 US Dollars.
