Cerebras-GPT 13B needs ~18.9 GB VRAM. RX 9070 XT 16GB has 16.0 GB. With Q3_K_S quantization, expect ~32 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.
Current mode
Balanced
Balanced for general local use. Keeps the ranking neutral across personal and serving workflows.

Offload
30%
It fits through host-memory offload, and offload is the main reason performance drops.
CPU or host-memory offload is active
About 20% 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 1.0 GB of extra host RAM just for the offloaded portion, before OS and other tools.

Yes, RX 9070 XT 16GB can run Cerebras-GPT 13B at Q3_K_S quantization (Very compromised (needs ~1 GB host RAM)). The recommended Q5_K_M requires 21.9 GB which exceeds available memory, but at Q3_K_S it needs only 18.9 GB. Expected decode speed: 32.4 tok/s.
Cerebras-GPT 13B (13B parameters) requires approximately 21.9 GB at Q5_K_M quantization. On RX 9070 XT 16GB, it fits at Q3_K_S using 18.9 GB.
The recommended quantization is Q5_K_M, but on RX 9070 XT 16GB the best fitting quantization is Q3_K_S, which uses 18.9 GB.
On RX 9070 XT 16GB, Cerebras-GPT 13B achieves approximately 32.4 tokens per second decode speed with a time-to-first-token of 5970ms using Q3_K_S quantization.
For coding workloads, Cerebras-GPT 13B on RX 9070 XT 16GB receives a F grade with 17.9 tok/s and 6K context.
On RX 9070 XT 16GB, Cerebras-GPT 13B can safely use up to 11K tokens of context at Q3_K_S quantization. The model's official context limit is 131K, but available memory constrains the safe maximum.
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.
