A M1 Max has 400GB/s of memory bandwidth but the CPU is only capable of using half of that (see https://tlkh.hashnode.dev/benchmarking-the-apple-m1-max#memo...). So a framework 13 with ddr 5 5600 with 86GB/s of memory bandwidth has a bit less than half, nowhere near ⅕th.

If we compare like-to-like the rtx 5070 in a framework 16 has 384GB/s on its own, add the 86 and the combined memory bandwidth is higher than a M1 Max.

I was being generous. These are just the pure bandwidth speeds. For my workflow when the CPU has to go back and forth with the RAM hudreds of times with unique queries, SoCs are hundreds times faster not 5 times.
