The model fits in shared memory, but shared-memory bandwidth is now the real limiter.
Fit does not mean dedicated-VRAM speed
Unified or shared memory can make a model technically fit, but sustained tokens per second may still trail a discrete high-bandwidth GPU with less total memory.
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.
Prioritize bandwidth, not only capacity
If this workload feels slow, the next useful step is often a GPU tier with materially faster memory bandwidth rather than only a small bump in capacity.

Yes, MacBook Pro M2 Max 96GB can run Llama 3.3 70B with a A grade (Tight fit). Expected decode speed: 5.9 tok/s.
Llama 3.3 70B (70B parameters) requires approximately 58.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Llama 3.3 70B is Q4_K_M, which balances quality and memory efficiency.
On MacBook Pro M2 Max 96GB, Llama 3.3 70B achieves approximately 5.9 tokens per second decode speed with a time-to-first-token of 32765ms using Q4_K_M quantization.
For coding workloads, Llama 3.3 70B on MacBook Pro M2 Max 96GB receives a A grade with 5.9 tok/s and 50K context.
On MacBook Pro M2 Max 96GB, Llama 3.3 70B can safely use up to 50K tokens of context. The model's official context limit is 128K, but available memory constrains the safe maximum.
Prioritize bandwidth, not only capacity. If this workload feels slow, the next useful step is often a GPU tier with materially faster memory bandwidth rather than only a small bump in capacity.
Not always. MacBook Pro M2 Max 96GB 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.
