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.

  • High energy efficiency with a low 35W TDP, making it ideal for small, low-power systems
  • Low heat generation; operates at cool temperatures (max around 66°C) and requires minimal cooling
  • Enables silent or near-silent PC builds because low thermal output allows for quiet fan profiles or fanless heatsinks
  • Reliable performance for daily productivity, light work, and basic multitasking
  • Supports modern features for its era, including DDR4 memory and hardware virtualization

What customers don't like about Intel Core i5-6600T

  • Lower performance compared to standard desktop models, sacrificing roughly 30% peak power for its low energy footprint
  • Poor price-to-performance ratio for gamers, as it often cost more than faster standard models at launch
  • Multiplier is locked, which strictly limits any potential for overclocking
  • Integrated graphics (UHD 530) are low-end and only suitable for older games at low settings
  • Limited longevity for modern heavy workloads; struggles with 4K content and demanding multitasking by current standards

Verdict

The Intel Core i5-6600T is a 6th-generation 'Skylake' quad-core desktop processor featuring 4 cores, 4 threads, and a 6MB Intel Smart Cache. Built on a 14nm lithography, it operates at a base clock speed of 2.70 GHz with a maximum turbo frequency of 3.50 GHz and includes integrated Intel HD Graphics 530. Its primary advantages are its low 35W Thermal Design Power (TDP), making it highly energy-efficient and ideal for compact, low-heat systems, and its support for both DDR4-2133 and DDR3L-1600 memory. However, its low-power 'T' designation results in lower performance compared to standard i5 models, it lacks Hyper-Threading, and it is now considered a legacy component as it is officially discontinued and lacks native support for Windows 11.
