M1 Max vs M2 Max
One generation apart. M2 Max delivers ~22–26% higher LLM throughput — a meaningful but not dramatic improvement.
M1 Max and M2 Max share the same tier positioning: high-performance MacBook Pro and Mac Studio chips with 30–40 GPU cores and 32–96 GB RAM. The M2 generation brings improved memory bandwidth efficiency, which translates directly to faster LLM token generation.
Benchmark comparison — 3 shared models
Best published result for each model on each chip family. Q4_K Medium quantization. Higher tok/s is better.
| Model | M1 Max (best) | M2 Max (best) | Difference |
|---|---|---|---|
| Llama 3.2 1B Instruct Q4_K - Medium |
125.8 tok/s M1 Max 32-core GPU, 32 GB |
153.0 tok/s M2 Max 38-core GPU, 32 GB |
+22% |
| Llama 3.1 8B Instruct Q4_K - Medium |
37.8 tok/s M1 Max 32-core GPU, 64 GB |
46.4 tok/s M2 Max 38-core GPU, 96 GB |

Chip specs compared
| Spec | M1 Max | M2 Max |
|---|---|---|
| GPU cores | 24 or 32 | 30 or 38 |
| Memory bandwidth | ~400 GB/s | ~400 GB/s |
| Max unified RAM | 64 GB | 96 GB |
| Largest model at Q4 | 32B (fits in 64 GB) | 48B+ (fits in 96 GB) |
| 70B models | No (64 GB max is tight) | Marginal (needs 128 GB for Q4) |
Neither M1 Max nor M2 Max can comfortably run 70B models — both peak below the ~48 GB needed for a Q4 70B. The RAM ceiling difference (64 GB vs 96 GB) enables M2 Max to run ~48B models that M1 Max can't reach.
Verdict
Going from 37.8 to 46.4 tok/s on Llama 3.1 8B is meaningful for a sustained coding session — roughly 2 seconds faster per typical response. The RAM ceiling difference (64 GB vs 96 GB) is the more important consideration for developers planning to run models larger than 14B. For M1 Max owners: the upgrade is reasonable if you need 96 GB RAM. For pure throughput, M4 Max delivers 55+ tok/s on the same model — the bigger jump.
