CPU Comparison
Apple M1 vs Intel Core i3-8145U
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.
Adequate for a single Word or Excel window, but modern heavy web applications will saturate the 4 threads quickly.
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.
Not capable of modern gaming. UHD 620 can only handle very old or lightweight 2D games.
Virtualization
Capable for a couple of light VMs, but not ideal for large parallel VM farms due to core count and memory ceiling.
4 threads and 4MB cache make virtualization practically impossible for anything beyond a tiny Linux container.
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.
The 10nm process provided good idle battery life for 2018-era laptops, though sustained loads drain the battery quickly due to the low core count.
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 hardware.
- 2 cores are insufficient for any modern AI workload.
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
- UHD 620 is not a gaming GPU.
- 2 cores cannot feed modern game engines.
- Playable only in legacy eSports titles at lowest settings.

Our Verdict on Each
A landmark chip that delivered class‑leading efficiency and single‑thread speed for thin laptops, still very capable for most users but increasingly outdated compared to M2/M3 and modern x86 rivals in multi‑thread and GPU workloads.
Best for: Used or refurbished M1 MacBook Air / Mac mini for general use, study, or light creative work at a low price
Read the full reviewHistorically significant for being Intel's first 10nm mobile i3 with hardware security fixes, but its 2-core layout and high $281 launch price make it entirely obsolete for modern computing.
Best for: Only if repairing an existing laptop that uses this specific chip and the board is not compatible with newer generations.
