Apple M4 vs Apple M4 Max
The M4 Max delivers 4.3x the FP32 throughput of the M4 (18 vs 4.3 TFLOPS dense). The M4 Max also carries 96 GB more memory (128 GB vs 32 GB).

What actually differs
Both GPUs launched in 2024: the M4 on Apple M4 and the M4 Max on Apple M4.
Dense throughput for the M4 against the M4 Max: FP32 4.3 vs 18 TFLOPS. Sparse figures, where the vendor publishes them, appear under each dense number in the performance table.
Memory is 32 GB against 128 GB, fed at 120 GB/s versus 546 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.
