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 i7-5775R

  • Industry-leading integrated graphics for its era (Iris Pro 6200), often outperforming competing AMD APUs
  • Includes 128MB of eDRAM (L4 cache), which significantly boosts performance in specific games and applications
  • Excellent power efficiency with a low 65W TDP, consuming up to 25% less power than predecessors like the i7-4790K
  • Strong performance in emulation (e.g., RPCS3 and Cemu) due to its unique cache structure
  • Low operating temperatures, often running cool even under moderate load
  • Compatible with older LGA 1150 (Z97/H97) motherboards, offering an upgrade path for existing systems

What customers don't like about Intel Core i7-5775R

  • Lower base and turbo clock speeds compared to previous generation 'Devils Canyon' chips
  • Reduced L3 cache (6MB vs 8MB) compared to other high-end i7 processors of its time
  • Limited overclocking headroom, with many units struggling to remain stable beyond 4.2–4.3 GHz
  • High initial launch price made it a poor value compared to buying a cheaper CPU paired with a discrete GPU
  • Stiff competition from the subsequent Skylake architecture which launched shortly after

Verdict

The Intel Core i7-5775R is a 5th-generation Broadwell processor built on a 14nm process, featuring 4 cores and 8 threads with a base frequency of 3.3 GHz and a maximum turbo boost of 3.8 GHz. Its most distinctive characteristic is the inclusion of 128 MB of eDRAM, which serves as a high-speed L4 cache to significantly enhance both its Iris Pro Graphics 6200 and general CPU performance in memory-bound tasks. This unique architecture makes it exceptionally efficient for its 65W TDP, providing strong gaming and emulation performance that often rivals higher-clocked successors. However, the processor suffers from a locked multiplier that restricts overclocking, a smaller 6 MB L3 cache compared to previous i7 models, and limited availability since it was primarily designed for BGA (soldered) motherboard configurations.
