The raw memory story may look fine, but the software ecosystem is still a constraint here.
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.
Runtime ecosystem is narrower than CUDA
Intel GPUs can look attractive on memory per dollar, but local AI tooling, kernels, and model coverage are still broader and easier on CUDA today.
Prefer CUDA if you want the path of least resistance
If your goal is maximum runtime coverage, easier troubleshooting, and better support for new local AI releases, CUDA is usually still the safer upgrade path.
Buy headroom, not only minimum fit
A slightly larger memory tier gives you safer context growth and makes the recommendation more future-proof.

Inference speed
Estimated decode speed (tokens/sec) for 1-bit Bonsai 27B at Q1_0_G128 across popular GPUs and Apple Silicon, using the fastest local runtime per device. Fastest is RTX 5090 32GB at ~156 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

-c 4096 -ngl 99Yes, Intel Arc B570 10GB can run 1-bit Bonsai 27B with a S grade (Runs with offload). Expected decode speed: 42.0 tok/s.
1-bit Bonsai 27B (27B parameters) requires approximately 9.7 GB of memory with Q1_0_G128 quantization.
The recommended quantization for 1-bit Bonsai 27B is Q1_0_G128, which balances quality and memory efficiency.
On Intel Arc B570 10GB, 1-bit Bonsai 27B achieves approximately 42.0 tokens per second decode speed with a time-to-first-token of 4610ms using Q1_0_G128 quantization.
For coding workloads, 1-bit Bonsai 27B on Intel Arc B570 10GB receives a S grade with 42.0 tok/s and 17K context.
On Intel Arc B570 10GB, 1-bit Bonsai 27B can safely use up to 17K tokens of context. The model's official context limit is 262K, but available memory constrains the safe maximum.
Prefer CUDA if you want the path of least resistance. If your goal is maximum runtime coverage, easier troubleshooting, and better support for new local AI releases, CUDA is usually still the safer upgrade path.
Often yes, if your goal is the easiest setup and the widest runtime support. Intel can offer attractive memory capacity, but CUDA still tends to win on tooling maturity, guides, kernels, and model coverage for local AI.
