What it is
Our main score for this model, 1–10. It combines specs, expert reviews, best-of lists and owners.
How we count it
Parts: Technical score 40%, Reviews score 25%, List score 25%, Sentiment score 10%
Marks: Each part gets a mark out of 10. For reviews, lists and owners, a typical model in this category gets about 8 and the best one gets 10.
No data yet: A part with no data shows "?". It counts as the mark of a weaker model in this category (4 in 5 models with data score higher). This way, models with reviews, lists and owners usually come out ahead.

What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.2 for now.

Third-party reviews

What customers like about Intel Core M-5Y31

  • Extremely low power consumption (4.5W TDP) which enables long battery life in thin devices
  • Supports fanless, passive cooling, allowing for silent and ultra-thin laptop and tablet designs
  • Reliable performance for everyday tasks like web browsing, office applications, and multimedia playback
  • Capable of high 'Turbo' clock speed bursts (up to 2.4 GHz) for snappy application launching
  • Integrated Intel HD Graphics 5300 supports modern APIs like DirectX 11.2 and OpenCL 2.0

What customers don't like about Intel Core M-5Y31

  • Significant performance degradation under continuous heavy load due to aggressive thermal throttling
  • Unsuitable for modern gaming, with most titles only playable on the lowest settings
  • Poor choice for demanding professional tasks such as video editing, media encoding, or large software compilation
  • Base clock speed is very low (0.9 GHz), which can lead to a sluggish feel during sustained background processes
  • Susceptible to heating up quickly despite its low wattage, which triggers the frequency drop

Verdict

The Intel Core M-5Y31 is an ultra-low voltage (ULV) dual-core SoC based on the 14nm Broadwell architecture, launched in late 2014. It features a base clock of 900 MHz with a Turbo Boost up to 2.4 GHz, 4 MB of L3 cache, and integrates Intel HD Graphics 5300 with 24 execution units. Its primary strength lies in its exceptional power efficiency, maintaining a standard TDP of just 4.5W (configurable from 3.5W to 6W), which allows for completely silent, fanless operation in extremely thin tablets and 2-in-1 laptops. However, its main drawbacks include significant performance degradation under sustained heavy workloads due to strict thermal and power limits, as well as very limited gaming capabilities that are only suitable for low-end or older titles.
