High-Performance Computing that’s Earth Friendly
summary
Claims that Unity’s DOTS (ECS, C# Job System, Burst) reorganizes data to cut memory traffic, cites a Google study where ~60% of energy moves data not computes, and reports a microbenchmark: 10,000 moving objects drops from 6.14 ms to 0.11 ms — 55x faster for that case. Burst adds Arm NEON intrinsics for up to 10x SIMD uplift, and the talk extrapolates savings (eg. a million-player title could save >6 years of CPU time per day) across the >200 billion Arm chips deployed.
