## Summary

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 outperform NVIDIA's GeForce RTX 5090 by 15-25% in 4K raster rendering and local AI workloads.

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.

## 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.

## Why it matters

A consumer GPU with 48 GB of fast VRAM would significantly lower the cost of running large local AI models like Llama 3 70B, which currently require multiple cards or enterprise hardware.
