Verdict

The Intel Core i7-5775C is a 5th-generation Broadwell processor built on a 14nm process, featuring 4 cores and 8 threads with a base clock of 3.3 GHz and a turbo frequency of 3.7 GHz. Its standout characteristic is the integrated Iris Pro Graphics 6200 paired with 128MB of dedicated eDRAM (L4 cache), which significantly boosts both graphical and certain CPU-bound tasks. Main pros include exceptional power efficiency with a low 65W TDP, compatibility with the existing LGA1150 socket on 9-series motherboards, and being fully unlocked for overclocking. However, it suffers from lower base and boost clock speeds compared to its 4th-gen predecessor (i7-4790K), a reduced 6MB L3 cache, and historically limited overclocking headroom, often hitting a wall around 4.2 GHz.
