Apple M3 vs Apple M3 Max
The M3 Max delivers 4.6x the FP32 throughput of the M3 (16 vs 3.5 TFLOPS dense). The M3 Max also carries 104 GB more memory (128 GB vs 24 GB).

What actually differs
Both GPUs launched in 2023: the M3 on Apple M3 and the M3 Max on Apple M3.
Dense throughput for the M3 against the M3 Max: FP32 3.5 vs 16 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 24 GB against 128 GB, fed at 100 GB/s versus 400 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.
