## AI overview

This article explains memory-level parallelism, the number of memory requests a processor core can keep in flight, and measures it with a pointer-chasing benchmark. Experiments on AWS compare how this capability evolved across Intel, AMD, and Graviton processors; the supplied evidence reports AMD reaching 58 concurrent cache lines on Turin.

## Source excerpt

When your program asks for memory that is not in cache, the processor has to go to RAM. That trip costs on the order of 100 nanoseconds. On a 3 GHz core, that is about 300 cycles of doing nothing. Memory latency has not improved in ten years. The 2016 Broadwell answers a random access ... Continue reading Memory-level parallelism: AMD is the king
