CPU Comparison
Apple M1 vs Intel Core i7-4558U
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.
High clock speeds ensure good performance in office apps.
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.
Iris 5100 allows for playable frame rates in older or well-optimized games.
Virtualization
Capable for a couple of light VMs, but not ideal for large parallel VM farms due to core count and memory ceiling.
Capable of running one light VM, but limited by 2 cores.
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.
28W TDP is warmer than 15W parts but justified by performance.
Specialized Performance
AI / ML
- 16‑core Neural Engine accelerates Core ML models

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
- Iris 5100 is a major step up from HD 4400
- Can run older games at low settings
- Not suitable for modern AAA titles

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class‑leading efficiency and single‑thread speed for thin laptops, still very capable for most users but increasingly outdated compared to M2/M3 and modern x86 rivals in multi‑thread and GPU workloads.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 reviewA premium 28W mobile CPU that combined high clock speeds with Iris graphics, delivering an excellent balance of CPU and GPU performance for 2013.
Best for: If you are considering a laptop with the Intel Core i7-4558U, you are likely looking at a used MacBook Pro or a premium ultrabook. This processor remains capable for everyday productivity, programming, and light 1080p video editing. The inclusion of Iris 5100 graphics provides a noticeable boost in graphical tasks compared to standard U-series chips. It is an excellent choice for users who need a compact, moderately powerful machine without paying the premium for modern hardware. However, be aware that it is an older Intel-based Mac, meaning it will eventually lose macOS support. Avoid this processor if you need to run modern AAA games or heavy 3D rendering workloads. It is best purchased at a discount for general use.
