What actually differs
Both GPUs launched in 2023: the M3 Max on Apple M3 and the M3 on Apple M3.
Dense throughput for the M3 Max against the M3: FP32 16 vs 3.5 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 128 GB against 24 GB, fed at 400 GB/s versus 100 GB/s. More memory per GPU means larger models fit before you have to shard across cards, which often matters more than raw TFLOPS for inference.
For LLM training and inference, weight the FP8 and FP16 rows and memory capacity most heavily. For scientific and HPC workloads, the FP64 row is the one to read.
