AMD Radeon leaks point to the Radeon RX 10800 XT as a card that could beat the RTX 5090 by 15-25% in 4K gaming. The same claim puts it ahead in local AI workloads too. That would reshape the top end of the GPU market if the numbers hold.
Radeon RX 10800 XT leaks
Moore's Law is Dead and Kepler_L2 are tied to the leak trail behind the Radeon RX 10800 XT. The card is described as RDNA 5-based, with up to 200 Compute Units, a 512-bit bus, up to 48 GB of GDDR7 memory, and 3.1–3.4 GHz frequencies on a 3 nm process. Those numbers describe a part built to push bandwidth and parallel work far beyond today's flagship class.
The article says 200 Compute Units at 64 stream processors per unit would yield 12,800 ALUs. That is still a rough way to compare it with NVIDIA's 21,760 FP32 compute cores in the RTX 5090. The raw count does not decide performance by itself, but it shows how much work AMD would have to extract from each unit to reach the claimed result.
RTX 5090 and RTX 6090
The GeForce RTX 5090 is described as using the GB202 GPU, with 170 active streaming multiprocessors out of 192 physically present on the die, plus 170 hardware RT Cores and 680 Tensor Cores. The article says the Radeon RX 10800 XT could still outpace it by 15-25% at 4K resolution in traditional raster rendering without ray tracing. That is the core claim buyers will care about first.
The comparison gets narrower once hybrid ray tracing enters the frame. The article says the Radeon RX 10800 XT would match the RTX 5090 there, while the GeForce RTX 6090 would keep a 35-50% edge in intensive panoramic path tracing. The RTX 6090 is described as Rubin-based with 192 active SMs and 24,576 CUDA cores, so the gap is not uniform across every workload.
Wave Matrix and AI
Wave Matrix units within the 200 CUs are said to enable full-fledged neural network-based FSR frame generation. The same leak set says the Radeon RX 10800 XT's 48 GB of GDDR7 would help in ROCm or HIP workloads. NVIDIA cards would still hold the lead in final rendering speed in professional 3D software with CUDA and OptiX support.
Whether AMD will actually release a Radeon RX 10800 XT with these specifications is not answered. For buyers, that leaves the practical choice unchanged for now: treat the card as a leak-driven target, not a shipping product, and wait for real silicon before betting on a 4K upgrade.
