Single-core memory bandwidth: Latency, Bandwidth, and Concurrency

John McCalpin

In my previous post , I reviewed historical data on single-core/single-thread memory bandwidth in multicore processors from Intel and AMD from 2010 to the present. The increase in single-core memory bandwidth has been rather slow overall, with Intel processors only showing about a 2x increase over the 13 years from 2010 to 2023.

Zero Configuration Service Mesh with On-Demand Cluster Discovery

The Netflix TechBlog

A brief history of IPC at Netflix Netflix was early to the cloud, particularly for large-scale companies: we began the migration in 2008, and by 2010, Netflix streaming was fully run on AWS. In 2010, however, nearly none of it existed: the CNCF wasn’t formed until 2015!

Amazon EC2 Cluster GPU Instances - All Things Distributed

All Things Distributed

By Werner Vogels on 14 November 2010 04:00 PM. Building general purpose architectures has always been hard; there are often so many conflicting requirements that you cannot derive an architecture that will serve all, so we have often ended up focusing on one side of the requirements that allow you to serve that area really well.

The evolution of single-core bandwidth in multicore processors

John McCalpin

Looking at sustained single-core bandwidth for a kernel composed of 100% reads, the trends for a large set of high-end AMD and Intel processors are shown in the figure below: So from 2010 to 2023, the sustainable single-core bandwidth increased by about 2x on Intel processors and about 5x on AMD processors.
