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 i5-12400T

  • Excellent value for money, often described as a 'budget king' for mid-range builds
  • Highly power efficient with a low 35W TDP, making it ideal for quiet or small form factor (SFF) systems
  • Strong single-core performance that excels in gaming and daily productivity tasks
  • Operates at very low temperatures, allowing for effective use with modest air cooling or even stock coolers
  • Includes integrated UHD 730 graphics, which is useful for office work or media transcoding without a discrete GPU

What customers don't like about Intel Core i5-12400T

  • Lower base and boost clock speeds compared to the standard i5-12400 to maintain the low power envelope
  • Lack of 'E-cores' (efficiency cores) results in lower multi-threaded performance for heavy workloads like 8K video editing
  • Can be difficult to find at retail, as 'T' series chips are primarily sold to system integrators (OEMs)
  • The included stock cooler, while functional, is often rated as inefficient by users for sustained heavy loads
  • Performance is significantly lower than higher-tier 12th gen or newer 14th gen processors in productivity benchmarks

Verdict

The Intel Core i5-12400T is a power-efficient 12th Gen Alder Lake desktop processor featuring 6 Performance-cores and 12 threads with a low 35W base TDP. It operates at a 1.80 GHz base frequency with a Max Turbo boost of 4.20 GHz, supported by 18 MB of Intel Smart Cache and 7.5 MB of L2 cache. Main characteristics include support for both DDR4-3200 and DDR5-4800 memory up to 128 GB, PCIe Gen 5.0/4.0 compatibility, and integrated Intel UHD Graphics 730. Its primary pros are exceptional energy efficiency and cool operation, making it ideal for compact mini-PCs or silent home-office builds where power consumption is a priority. However, its main cons are lower clock speeds and roughly 17% slower multi-threaded performance compared to the standard 65W i5-12400 variant.
