Yes. Gemma 4 E2B (effective 2.3B) fits in fast memory on M3 Max (40c GPU) 64GB at Q8_0 (7.2 GB needed, 48.0 GB usable), about 53 tok/s (estimate).
Hardware: M3 Max (40c GPU) 64GB · Model: Gemma 4 E2B (effective 2.3B)
M3 Max (40c GPU) 64GB has 64 GB of unified memory and 400 GB/s of memory bandwidth. M1 Max (32c GPU) 64GB and M2 Max (30c GPU) 64GB and M2 Max (38c GPU) 64GB have the same memory and bandwidth, so the fit numbers match; this page is M3 Max (40c GPU) 64GB. The checker leaves macOS a share of unified memory, so Ollama can use 48.0 GB. Gemma 4 E2B (effective 2.3B) (5.12B, Google) at Q8_0 is a 6 GB download and needs 7.2 GB with headroom for about 8k tokens.
