Apertus v1.5 70B needs ~50.1 GB but Intel Arc A370M 4GB only has 4.0 GB. Try a smaller quantization or lighter model.
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.

Usable VRAM is the main blocker for this model.
Not enough usable memory
The model needs 50.1 GB, but this setup only exposes 4.0 GB of usable VRAM.
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.
Add more VRAM headroom
The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
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.

Inference speed
Estimated decode speed (tokens/sec) for Apertus v1.5 70B at Q4_K_M across popular GPUs and Apple Silicon, including multi-GPU rigs, using the fastest local runtime per device. Fastest is 2× RX 7900 XTX 24GB at ~17 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.

No, Apertus v1.5 70B requires more memory than Intel Arc A370M 4GB provides.
Apertus v1.5 70B (72B parameters) requires approximately 50.1 GB of memory with Q4_K_M quantization.
The recommended quantization for Apertus v1.5 70B is Q4_K_M, which balances quality and memory efficiency.
On Intel Arc A370M 4GB, Apertus v1.5 70B achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using Q4_K_M quantization.
For coding workloads, Apertus v1.5 70B on Intel Arc A370M 4GB receives a F grade with 2.0 tok/s and 4K context.
On Intel Arc A370M 4GB, Apertus v1.5 70B can safely use up to 4K tokens of context. The model's official context limit is 262K, but available memory constrains the safe maximum.

Add more VRAM headroom. The first useful upgrade is more dedicated VRAM so you can fit the model without shrinking context or dropping to a much lower quant.
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.
