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.

Inference speed
Estimated decode speed (tokens/sec) for Kimi Linear 48B A3B at Q4_K_M across popular GPUs and Apple Silicon, including multi-GPU rigs, using the fastest local runtime per device. Fastest is 2× RX 7900 XTX 24GB at ~40 tok/s. Speed is memory-bandwidth bound, so cards that fit the whole model in VRAM run far faster than ones that offload to system RAM.

-c 4096 -ngl 99Yes, Mac mini M4 64GB can run Kimi Linear 48B A3B with a A grade (Tight fit). Expected decode speed: 5.3 tok/s.
Kimi Linear 48B A3B (48B parameters) requires approximately 38.9 GB of memory with Q4_K_M quantization.
The recommended quantization for Kimi Linear 48B A3B is Q4_K_M, which balances quality and memory efficiency.
On Mac mini M4 64GB, Kimi Linear 48B A3B achieves approximately 5.3 tokens per second decode speed with a time-to-first-token of 36449ms using Q4_K_M quantization.
For coding workloads, Kimi Linear 48B A3B on Mac mini M4 64GB receives a A grade with 5.3 tok/s and 140K context.
On Mac mini M4 64GB, Kimi Linear 48B A3B can safely use up to 140K tokens of context. The model's official context limit is 1.0M, 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. Mac mini M4 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.
