AMD Radeon RX 8800 XT to Boost Over 3GHz, will Feature Tensor Units, Fabbed on 4nm Node

AMD's RDNA 4 samples, fabbed on 4nm, are boosting between 3GHz and 3.3GHz

AMD’s Radeon RX 8000 GPUs are expected to land in the second half of the year, targeting the budget and midrange segments for gaming supremacy. The RX 8900 XTX was an advanced chiplet design with 10+ dies but was canceled. This leaves the RX 8800 XT, 8700 XT, and the RX 8600 XT. As reported previously, the RX 8800 XT will be a $500 GPU, offering comparable performance to the RX 7900 XTX (for ~half as much $$$).

Today’s leak (via Moore’s Law is Dead) claims that the RDNA 4 family will be fabbed on TSMC’s N4P (4nm+) process. Engineering samples are currently boosting between 3GHz and 3.3GHz. For reference, The RX 7900 XTX boosts up to 2499MHz, while the 7900 XT tops out at 2394 MHz. The RDNA 4 SIMD will include a Tensor core equivalent (matrix unit) and FP8 units for AI workloads.

The Radeon RX 8800 XT (Navi 48) will deliver rasterization performance between the RX 7900 XT and 7900 XTX. It is expected to have a die size of up to 350mm2 and a 256-bit memory controller. GDDR7 memory is unlikely, with high-speed GDDR6 (20Gbps) being the likely candidate.

The Radeon RX 8600 XT (Navi 44) will deliver rasterization performance between the RX 7700 XT and 7800 XT. It will be powered by a relatively small die with an area of 210mm2, with a 128-bit memory controller. The RDNA 4 GPUs are expected to be launch-ready by the end of 2024 but will likely be released in early 2025.

The reason? Midrange RDNA 3 is doing well against the RTX 40 Supers, and the RTX 5090/5080 will be the only Blackwell GPUs to land this year. The RTX 5070 and 5070 Ti, the rivals to RDNA 4, will likely drop anchor in 2025.
