CMN-600

You need much more than a good CPU core to conquer the server world. As more cores are added, the way data moves from one part of the silicon to another gets more important. ARM has announced today a new and faster member to their SoC interconnect IP offerings in the form of CMN-600 (CMN stands for 'coherent mesh network', as opposed to cache coherent network of CCN). This is a direct update to CCN-500 series, which we've discussed at AnandTech before. The idea behind a coherent mesh between cores as it stands in the ARM Server SoC space is that you can put a number of CPU clusters (e.g. four lots of 4xA53) and accelerators (custom or other IP) into one piece of...
