DeepSeek R1 Distill 8B needs ~6.6 GB VRAM. RX 5600 XT 6GB has 6.0 GB. With Q2_K quantization, expect ~27 tok/s.
Operating mode
Interactive favors responsiveness, while light API and scale-out lean harder on serving readiness. The fit stays the same, but the recommendation lens changes.

Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 10% of the working set spills out of accelerator memory, which usually hurts latency and sustained decode throughput.
Very little memory headroom
You can run the model, but there is not much room left for longer context, bigger batches, extra apps, or future model updates.
Remove offload with more accelerator memory
Prioritize a GPU or unified-memory tier that fits the whole model natively. Removing offload usually helps more than small compute gains.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.
Increase host RAM if you keep offloading
This setup may need roughly 0.3 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RX 5600 XT 6GB can run DeepSeek R1 Distill 8B at Q2_K quantization (Very compromised (needs ~0.3 GB host RAM)). The recommended Q4_K_M requires 8.3 GB which exceeds available memory, but at Q2_K it needs only 6.6 GB. Expected decode speed: 27.1 tok/s.
DeepSeek R1 Distill 8B (8B parameters) requires approximately 8.3 GB at Q4_K_M quantization. On RX 5600 XT 6GB, it fits at Q2_K using 6.6 GB.
The recommended quantization is Q4_K_M, but on RX 5600 XT 6GB the best fitting quantization is Q2_K, which uses 6.6 GB.
On RX 5600 XT 6GB, DeepSeek R1 Distill 8B achieves approximately 27.1 tokens per second decode speed with a time-to-first-token of 7131ms using Q2_K quantization.
For coding workloads, DeepSeek R1 Distill 8B on RX 5600 XT 6GB receives a F grade with 12.4 tok/s and 4K context.
On RX 5600 XT 6GB, DeepSeek R1 Distill 8B can safely use up to 11K tokens of context at Q2_K quantization. The model's official context limit is 33K, but available memory constrains the safe maximum.
