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.

-c 4096 -ngl 99Yes, Mac Studio M1 Ultra 64GB can run Llama 3.2 1B Instruct Q8 0 with a C grade (Runs well). Expected decode speed: 14.0 tok/s.
Llama 3.2 1B Instruct Q8 0 (1B parameters) requires approximately 8.7 GB of memory with Q6_K quantization.
The recommended quantization for Llama 3.2 1B Instruct Q8 0 is Q6_K, which balances quality and memory efficiency.
On Mac Studio M1 Ultra 64GB, Llama 3.2 1B Instruct Q8 0 achieves approximately 14.0 tokens per second decode speed with a time-to-first-token of 13829ms using Q6_K quantization.
For coding workloads, Llama 3.2 1B Instruct Q8 0 on Mac Studio M1 Ultra 64GB receives a C grade with 14.0 tok/s and 5.1M context.
On Mac Studio M1 Ultra 64GB, Llama 3.2 1B Instruct Q8 0 can safely use up to 5.1M tokens of context. The model's official context limit is —, but available memory constrains the safe maximum.
Not always. Mac Studio M1 Ultra 64GB 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.
