Does the speed (bandwidth) of memory matter?

Thank you @septc , I have posted a code here,

Memory bandwidth test code for M1 and PC

Dear all, I just wanted to test a code, to see if there are speed dfference between M1 and PC. I have a code, I have to say, this definitely may not be the best code to test memory bandwidth, but I wanted to share the test code with you. You may test and report the result, especially if you have M1, M1 Pro, M1 Max, or even M1 Ultra. The code is basically solving a simple 2-equation stochastic differential equation (SDE). Because it is stochastic differential equation, you can imagine you need…

You may test when you have time. Thanks again!
