AMD Radeon RX 8800 XT

The AMD Radeon RX 8800 XT is an unreleased desktop graphics card that was planned to launch in 2024. It is built on the RDNA 4.0 GPU microarchitecture (codename Navi 48) and is manufactured on a 4 nm process.

Memory

The RX 8800 XT has 16 GB of GDDR6 memory, with a 2,438 MHz memory clock and a 256 bit interface. This gives it a memory bandwidth of 624.1 Gb/s, which affects how fast it can transfer data to and from memory. GPU memory stores temporary data that helps the GPU with complex math and graphics operations. More memory is generally better, as not having enough can cause performance bottlenecks.

Cores and Clock Speeds

The RX 8800 XT includes 3,584 stream processors (SPs), the processing units for handling parallel computing tasks. The GPU operates at a core clock speed of 1,295 MHz and can dynamically boost its clock speed up to 2,430 MHz. It usually operates at 2,124 MHz during typical gaming workloads. Complementing the processing units are 224 texture mapping units (TMUs) for efficient texture filtering and 96 render output units (ROPs) for pixel processing. Additionally, the GPU features 56 ray accelerators dedicated to real-time ray tracing calculations.

Compatibility & Power Consumption

The RX 8800 XT occupies 2 PCIe expansion slots. It supports HDMI 2.1a, DisplayPort 2.1 display connections. AMD recommends a power supply of at least 550 W to handle the GPU's thermal design power (TDP) of 220 W.
