AMD wants to make its chips 30 times more energy-efficient by 2025 [techspot.com]

Today, [AMD] announced [amd.com] its most ambitious goal yet—to increase the energy efficiency of its Epyc CPUs and Instinct AI accelerators 30 times by 2025. This would help data centers and supercomputers achieve high performance with significant power savings over current solutions.

If it achieves this goal, the savings would add up to billions of kilowatt-hours of electricity saved in 2025 alone, meaning the power required to perform a single calculation in high-performance computing tasks will have decreased by 97 percent.

Increasing energy efficiency this much will involve a lot of engineering wizardry, including AMD's stacked 3D V-Cache [techspot.com] chiplet technology. The company acknowledges the difficult task ahead of it, now that "energy-efficiency gains from process node advances are smaller and less frequent."

What does it mean? [amd.com]

In addition to compute node performance/Watt measurements, to make the goal particularly relevant to worldwide energy use, AMD uses segment-specific datacenter power utilization effectiveness (PUE) with equipment utilization taken into account. The energy consumption baseline uses the same industry energy per operation improvement rates as from 2015-2020, extrapolated to 2025. The measure of energy per operation improvement in each segment from 2020-2025 is weighted by the projected worldwide volumes multiplied by the Typical Energy Consumption (TEC) of each computing segment to arrive at a meaningful metric of actual energy usage improvement worldwide.
