AMD Radeon RX 6600 XT 8GB Specs

The AMD Radeon RX 6600 XT is based on the RDNA 2.0 7nm architecture with 2048 Stream Processors. It has a base clock of 1968 MHz, game clock of 2359 MHz and a boost clock of 2589 MHz. There are 11.1 billion transistors, 128 texture units and 64 ROPs.

The AMD Radeon RX 6600 XT 8GB is a desktop graphics card in the Radeon RX 6000 series using a die size of 237 mm². Its codename is Navi 23 and the fabrication process is TSMC 7nm. There are 32 ray tracing cores and it also has 32 compute units. The amount of L2 cache comes in at 2MB and it additionally has 32MB of infinity cache.

On board the AMD Radeon RX 6600 XT is 8GB of GDDR6 memory running at an effective memory clock of 16000 MHz. The memory has an interface width of 128-bit and a bandwidth of 256 GB/s.

The theoretical performance is based on the clock speed, cores and the floating point operations per clock cycle. The FP16 half precision theoretical performance is 21.209088 TFLOPS, 10.604544 TFLOPS is the single precision FP32 performance and the double precision comes in at 0.662784 TFLOPS. The FP16 half precision floating point operations per clock cycle is 4, for single precision FP32 it is 2 and 1/8 is for double precision FP64. The texture fillrate is 331.392 GT/s and the pixel fillrate is 165.696 GP/s.

For technologies, there is DirectX Version 12 and AMD FreeSync. There is OpenCL 2.1, OpenGL 4.6 and Shader Model 6.7. The card is VR ready but is not Crossfire compatible. Also included is AMD Software: Adrenalin Edition, AMD FidelityFX Super Resolution, AMD Link, AMD Noise Suppression, AMD Radeon Super Resolution, AMD Smart Access Memory VSR (4K), AMD Privacy View, AMD Radeon Boost, AMD Radeon Anti-Lag, AMD Radeon Image Sharpening, AMD Enhanced Sync Technology, AMD Radeon Chill, TrueAudio Next and The Vulkan API.

For connectivity, there is Display Port 1.4a and HDMI 2.1. The maximum resolution is 7680 x 4320. There is no USB-c, DVI or VGA on this card. In order to power the AMD Radeon RX 6600 XT, it needs 1 x 8 pin power connector from your PSU as it uses 160 W of power. AMD recommend a 500 W PSU for this graphics card. This graphics card uses the PCIe 4.0 x8 interface to connect to the motherboard.

The maximum HDMI resolution is 7680×4320 @ 60Hz and the maximum display port resolution is 7680×4320 @ 120Hz.

The RX 6600 XT is a 2 Slot card costing $379 USD at its release on the 11th August 2021. View more RX 6600 XT variants here.
