How do latency and bandwidth relate to the cost model for the code in the benchmark? When creating the model discussed in the post, we're using it to try to make a static prediction about how the code will execute. Note that the goal of the post is not to merely measure the memory access performance, it's to understand the specific microarchitecture and how it might deliver the benefits that we see in benchmarks.
