An Underside tool

Test what your Mac can really do with AI.

Name: CoreScope
Author: Underside

CoreScope is your Apple Silicon Mac's local AI benchmark. It measures real inference capability across the CPU, GPU, and Neural Engine, then puts memory and thermal behaviour in context in real time.

A benchmark you can read

Local AI performance, beyond a single score.

CoreScope separates the measurements so you can see which resources your Mac uses throughout the benchmark.

Inference throughput

Follow sequential and parallel phases alongside CPU, GPU, and Neural Engine results.

Memory & bandwidth

Observe the app's memory footprint and memory-copy bandwidth during the benchmark.

Thermals & chip

Keep temperature and core load in view while the test runs, with an animated activity view.

Inside the app

Views for understanding every phase.

CoreScope dashboard showing CPU GPU and Neural Engine — Dashboard: scores, progress, and a comparison of compute engines.

CoreScope memory and bandwidth view — Memory: application footprint and bandwidth stability.

Live thermal view in CoreScope — Thermals: temperature monitoring while the test runs.

CoreScope view of CPU GPU and Neural Engine cores — Chip: a view of the detected CPU, GPU, and Neural Engine cores.

Animated chip activity visualizer in CoreScope — Visualizer: a graphic reading of CPU, GPU, Neural Engine, and memory activity.
