This setup is broadly balanced for this model.
Shared-memory contention still exists
The OS, browser, and inference runtime all compete for the same physical memory pool, so real-world headroom is less forgiving than raw capacity suggests.

Yes, Mac Studio M3 Ultra 256GB can run InternVL2 8B with a A grade (Runs well). Expected decode speed: 112.0 tok/s.
InternVL2 8B (8B parameters) requires approximately 35.4 GB of memory with Q4_K_M quantization.
The recommended quantization for InternVL2 8B is Q4_K_M, which balances quality and memory efficiency.
On Mac Studio M3 Ultra 256GB, InternVL2 8B achieves approximately 112.0 tokens per second decode speed with a time-to-first-token of 1729ms using Q4_K_M quantization.
For coding workloads, InternVL2 8B on Mac Studio M3 Ultra 256GB receives a A grade with 112.0 tok/s and 8K context.
On Mac Studio M3 Ultra 256GB, InternVL2 8B can safely use up to 8K tokens of context. The model's official context limit is 8K, but available memory constrains the safe maximum.
Not always. Mac Studio M3 Ultra 256GB can often fit larger models thanks to unified memory, but a discrete GPU with dedicated high-bandwidth VRAM may still decode faster once the model fits. For this combination, the important distinction is capacity versus sustained throughput.
