CPU Comparison
Apple M4 vs Intel Core Ultra 7 255H
A side-by-side comparison of specs, performance and value. Apple M4 is an ARM-based system-on-chip built on TSMC’s second-generation 3nm process, pairing up to 10 CPU cores (4 performance + 6 efficiency) with up to a 10-core GPU, a 16-core Neural Engine, and a new display engine. It introduces hardware-accelerated ray tracing and mesh shading to iPad and Mac, and adds AV1 decode in the media engine, targeting high-performance, power-efficient workloads across tablets, laptops, and desktops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very fast single-thread performance and strong multi-core scaling within its power envelope, suitable for demanding productivity workloads on macOS and iPadOS.
Snappy application performance and strong multi-core scaling for a 28W chip.
Gaming
Arc 140T graphics allow for respectable 1080p gaming at medium settings without a discrete GPU.
Virtualization
Capable of running light VMs, though limited by 16 threads.
Efficiency
High performance-per-watt; Apple claims the same performance as M2 using roughly half the power in tested workloads, and M4 devices typically run cool and quiet.
Excellent efficiency thanks to LP E-Cores and mixed TSMC nodes.
