Whilst there are certain operations in a datacenter that require a fast single core, that is not the majority of workloads. This is why we have virtualisation and containers today. All that compute capability is going to waste. Worse, that virtualisation itself causes an overhead and consumes power and CPU cycles. With more cores, we have less overhead due to virtualisation.

However, it’s not just about the processor. Bamboo have re-imagined the server and removed unnecessary components that require power. This means that it is possible to get a massive compute density of around 5:1 compared to traditional servers, and using about 20% of the power needed.

Solid part, but still don’t see the utility in such platforms as servers because there’s sort of a baseline level of (single-core) performance necessary for useful applications, and those (A72-based) parts just don’t have it. Likewise, the Qualcomm part has 1 fast core, 3 mostly fast cores, and 4 horrifyingly slow cores, the asymmetry of which is also suboptimal to servers.
