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, NVIDIA DGX Spark 128GB can run Command A 111B with a S grade (Runs well). Expected decode speed: 2.6 tok/s.
Command A 111B (111B parameters) requires approximately 85.6 GB of memory with Q4_K_M quantization.
The recommended quantization for Command A 111B is Q4_K_M, which balances quality and memory efficiency.
On NVIDIA DGX Spark 128GB, Command A 111B achieves approximately 2.6 tokens per second decode speed with a time-to-first-token of 73308ms using Q4_K_M quantization.
For coding workloads, Command A 111B on NVIDIA DGX Spark 128GB receives a S grade with 2.6 tok/s and 111K context.
On NVIDIA DGX Spark 128GB, Command A 111B can safely use up to 111K tokens of context. The model's official context limit is 262K, 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. NVIDIA DGX Spark 128GB 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.
