CPU Comparison
Apple M1 vs Core i7-620UM
A side-by-side comparison of specs, performance and value. The Apple M1 is an 8-core ARM-based system-on-a-chip (SoC) that marked Apple’s transition from Intel to its own Apple Silicon for the Mac, combining four high‑performance and four efficiency cores, an 8‑core integrated GPU, and a 16‑core Neural Engine on a 5 nm process.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Very responsive for everyday tasks, Xcode builds, and light creative work; benefits from fast single‑core and SSD, but heavy multi‑thread workloads are constrained by 8 threads.
Will struggle immensely with modern web and software.
Gaming
Competent for 1080p gaming in macOS and via Rosetta 2 for many titles, but the 8‑core GPU and 8–16 GB memory limit modern AAA performance and resolution scaling.
No modern gaming capabilities.
Virtualization
Capable for a couple of light VMs, but not ideal for large parallel VM farms due to core count and memory ceiling.
Lacks the power for practical virtualization.
Efficiency
Outstanding performance per watt; MacBook Air and 13‑inch MacBook Pro with M1 delivered dramatically better battery life and lower heat than comparable Intel Macs.
Good for 2010, obsolete now.
Specialized Performance
AI / ML
- 16‑core Neural Engine accelerates Core ML models
- CPU and GPU also provide ML accelerators for framework‑level ops
- Not designed for large‑scale training or server‑side inference
- No AI capabilities.
Content Creation
Gaming
- 8‑core GPU comparable to low‑end discrete GPUs of its era in some Metal titles
- Rosetta 2 adds overhead for x86 games; some titles have compatibility or performance quirks
- 16 GB memory limit and 8 GPU cores cap texture resolutions and frame rates in modern AAA games
- Ironlake graphics are insufficient for any 3D gaming.
