CPU Comparison
Apple M2 vs Intel Core i7-1255U
A side-by-side comparison of specs, performance and value. The Apple M2 is a second‑generation 5 nm ARM‑based system‑on‑chip for Macs, with an 8‑core CPU, up to a 10‑core GPU, 16‑core Neural Engine, and 100 GB/s unified memory bandwidth, designed for thin‑and‑light laptops and compact desktops.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very strong single‑thread and good multi‑thread performance for everyday apps and light creator workloads.
Highly responsive for daily office tasks, with plenty of E-cores to keep background apps from slowing down the system.
Gaming
Solid for 1080p and many 1440p titles at medium–high settings; not intended for high‑refresh 4K gaming or heavy ray tracing.
Can run esports games like League of Legends smoothly, but struggles with modern AAA titles on integrated graphics.
Virtualization
Capable of light VM/container use, but limited to 8 threads and not aimed at heavy server workloads.
Good for light Docker containers, but 2 P-cores limit performance when running full Windows VMs.
Efficiency
Outstanding performance per watt; typically around 20 W CPU package power under multi‑threaded load, far below comparable x86 ultrabook chips.
Excellent power management ensures long battery life during typical office use.
Specialized Performance
AI / ML
- 16‑core Neural Engine at 15.8 TOPS
- Good for on‑device inference and Core ML workloads
- No large‑scale training focus; more for consumer features than datacenter AI
- No NPU
- AI workloads handled by CPU/GPU
Content Creation
Gaming
- Integrated 8–10 core GPU with up to 3.6 TFLOPS FP32
- Good for 1080p and some 1440p gaming at medium–high settings
- Limited by unified memory bandwidth and 8 CPU threads for CPU‑heavy titles
- Best experienced in macOS; Windows via virtualization or translation has overhead
- Iris Xe 96EU handles 1080p low settings for older games
- Throttles under sustained 3D loads
- Best paired with a discrete GPU for serious gaming

Strengths & Weaknesses
Pros
- Very strong single‑core performance for an ultrabook‑class chip
- Integrated 8–10 core GPU with up to 3.6 TFLOPS and hardware ProRes acceleration
- Unified memory architecture with 100 GB/s bandwidth simplifies development and avoids CPU–GPU copies
- 16‑core Neural Engine accelerates on‑device ML workloads
- Fanless designs in MacBook Air and very quiet operation under typical loads
Cons
- Not sold as a standalone CPU; only available inside Macs
- No user‑upgradable RAM or PCIe slots; I/O limited to what Apple provides
- Only 8 CPU threads; heavy multi‑threaded workloads are limited compared to higher‑core M2 Pro/Max or x86 chips
- CPU efficiency is slightly worse than M1 at maximum performance due to higher clocks and power
- Gaming performance is constrained by 8 threads and integrated GPU; not a gaming‑focused SoC
Pros
- Excellent performance-per-watt
- Very flexible memory support
- Good single-core burst performance
- Plenty of PCIe lanes for an ultrabook chip
- Reliable Iris Xe integrated graphics
Cons
- Only 2 P-cores limit heavy multi-threading
- Soldered to the motherboard
- Can get warm during 55W turbo bursts
- Not suitable for gaming without a discrete GPU
