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 Falcon H1 Tiny 90M Instruct at F16 quantization (Runs well). The recommended Q4_K_M requires 1.4 GB which exceeds available memory, but at F16 it needs only 14.5 GB. Expected decode speed: 2.0 tok/s.
Falcon H1 Tiny 90M Instruct (0.09000000357627869B parameters) requires approximately 1.4 GB at Q4_K_M quantization. On NVIDIA DGX Spark 128GB, it fits at F16 using 14.5 GB.
The recommended quantization is Q4_K_M, but on NVIDIA DGX Spark 128GB the best fitting quantization is F16, which uses 14.5 GB.
On NVIDIA DGX Spark 128GB, Falcon H1 Tiny 90M Instruct achieves approximately 2.0 tokens per second decode speed with a time-to-first-token of 96800ms using F16 quantization.
For coding workloads, Falcon H1 Tiny 90M Instruct on NVIDIA DGX Spark 128GB receives a F grade with 2.0 tok/s and 4K context.
On NVIDIA DGX Spark 128GB, Falcon H1 Tiny 90M Instruct can safely use up to 15.1M tokens of context at F16 quantization. The model's official context limit is —, 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.
