CPU Comparison

Apple M1 vs Core i7-5557U

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.

Performance Compared

Productivity

Apple M1Best88

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.

Core i7-5557U45

High clocks provide snappy performance for everyday tasks.

Gaming

Apple M1Best72

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.

Core i7-5557U35

Iris 6100 allows for decent 720p/1080p low gaming in older titles.

Virtualization

Apple M1Best68

Capable for a couple of light VMs, but not ideal for large parallel VM farms due to core count and memory ceiling.

Core i7-5557U20

Dual-core limits VMs, but clock speed helps.

Efficiency

Apple M1Best95

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.

Core i7-5557U35

28W TDP is less efficient than 15W U-series chips.

Specialized Performance

AI / ML

Gaming

Apple M1Good for casual and older titles
  • 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
Core i7-5557UModerate
  • Better than standard integrated graphics
  • Can play older 3D games
  • Not suitable for modern AAA titles

Industry Impact

Gaming
Moderate – pushed Windows OEMs to prioritize efficiency and integrated GPU performance in thin laptops, but M1’s gaming impact is limited by macOS software and GPU power.
Low
Workstations
High – demonstrated that ARM SoCs could compete with x86 in content creation and pro workloads at lower power, influencing subsequent Apple Silicon Pro/Max and ARM server efforts.
Low
Content Creation
High – made 4K video editing and photo editing accessible in thin, quiet laptops, changing expectations for what “ultrabook‑class” devices could do.
Moderate
Virtualization
Moderate – showed efficient VMs on ARM laptops, but x86 server and cloud ecosystems still dominate.
Low
