AMD Radeon RX 6800, AI & Machine Learning Benchmarks & Specs

16GB · AI Score 2.3/100 · anchored estimate vs 51 measured cards

2.3 AI Score Includes estimates

We have not run AMD Radeon RX 6800 on our bench. These figures are anchored estimates, interpolated per workload against the 51 GPUs we did measure (confidence: low). On Llama 3.1 8B (Q4_K_M) AMD Radeon RX 6800 should deliver about 80.3 tokens/sec. Llama 3.3 70B does not fit. It needs roughly 42GB and this card has 16GB. 2 of the 12 workloads won't fit on 16GB at the tested precision, Qwen3 32B, Llama 3.3 70B. We publish those as hard gates rather than quietly dropping to a smaller quant. Image, video and 3D models aren't listed for this card. They're built for NVIDIA's CUDA, and on AMD they only run through ROCm workarounds whose speed depends more on the driver and OS than on the card, so we don't estimate them, and they count as not supported in the AI score. For text generation (llama.cpp runs natively on ROCm and Vulkan), the numbers above hold up.

How this estimate is derived. This card hasn’t been through our bench yet, so its numbers are anchored estimates, interpolated from the 51 first-party measured cards (Bandwidth Theil-Sen ladder off NVIDIA anchors × vendor factor (LLM ×0.85, diffusion ×0.5); realistic VRAM floors). The VRAM “won’t fit” gates are exact, since they’re pure capacity limits. Confidence: low. Estimates are replaced with measured data as more silicon goes through the bench. Full methodology →

Verdict, capable, but 16GB sets the ceiling

AMD Radeon RX 6800 scores 2.3/100, #69 of 102. It ran 3 of 12; 2 exceeded its 16GB. Figures are anchored estimates, not measurements, we flag that on every row.

The silicon

Transistors26,800 million
Die size520 mm²
Process node7 nm
Fabricated byTSMC
Transistor density51.5 million per mm²

Denser than 85% of the 746 cards we have silicon data for. Density is the clearest measure of what a process node bought: a card that gained it without growing the die got its speed from the fab rather than the architecture.
