AMD Radeon RX 10800 XT could outperform RTX 5090, insider leaks suggest
Insider leaks attribute massive specifications to AMD's upcoming flagship graphics card, the Radeon RX 10800 XT, which is based on the RDNA 5 microarchitecture. Leaked details suggest the chip could feature up to 200 Compute Units, a 512-bit bus, up to 48 GB of fast GDDR7 memory, and operating frequencies between 3.1 and 3.4 GHz on a 3 nm process. These specifications could allow the card to…
Key points
- Leaked AMD Radeon RX 10800 XT specs include up to 200 Compute Units and 48 GB of GDDR7 memory.
- The card could outperform the NVIDIA RTX 5090 by 15-25% in 4K raster rendering.
- The 48 GB VRAM would enable running Llama 3 70B locally on a single GPU.
For local AI tasks, the rumored 48 GB of video memory would allow users to run large language models like Llama 3 70B directly on a single GPU. This memory capacity would surpass the RTX 5090's reported 32 GB, giving AMD an advantage in processing larger batch sizes and loading complex scenes. However, NVIDIA's upcoming Rubin-based RTX 6090 is expected to retain the lead in absolute graphics power, path tracing, and CUDA-based professional rendering.
Radeon RX 10800 XT can outperform the RTX 5090 by 15-25% in 4K gaming and local AI
