Intel Core i7 7740X CPU Review

Final Thoughts and Conclusion

Intel has obviously put some serious work into optimizing their 14 nm process. Kaby Lake isn’t a massive jump from Skylake, however it does offer higher speeds and lower power consumption. Both are gladly welcome.

The Core i7 7740X preformed excellent in our battery of tests. While it didn’t always best the i7 7700K, it came out on top more often than not. Overclocking with Kaby Lake-X is a dream. Our i7 7740X overclocked almost identical to our previously tested i7 7700K and that easily hit 5 GHz. Voltage was quite good at 1.25v.

The Core i7 7740X is a bit of an oddity to me. I don’t quite understand why Intel chose to release 4-Core processors with the X299 chipset. All the processors for both the previous X79 and X99 HEDT have included quad channel memory controllers. The i5 7640X and i7 7740X use dual channel memory controllers. Just looking at the specifications, there doesn’t seem to be any real reason for the i5 7640X and i7 7740X.

Intel has priced Core i7 7740X at the same price as the Core i7 7700K, at $339 but is currently around $350 at Newegg and Amazon as of this writing. That sounds good until you take into account of the X299 platform being quite a bit more expensive than the Z270 platform. X299 does have its advantages, but for most users they won’t use them.


  • Better Power Consumption than Skylake
  • Very Reasonable Price
  • Excellent Single-threaded Performance


  • Very little performance advantage over the Core i7 7700K
  • More expensive platform than the similar perfoming Core i7 7700K
