Intel Core i7-7740X ‘Kaby Lake-X’ 4C8T CPU Review (inc. 5.1GHz OC)

The market for people buying an expensive CPU and using it for gaming at 1080p is likely to be very slim. What 1080p does is give a good indication of the CPU’s raw gaming performance as GPU power is sufficient to push frame rates to a level where the CPU and memory limitations can be observed.

We supplement the 1080p gaming results with a pair of games tested at 1440P and 4K. We chose Ghost Recon Wildlands and GTA V as they are computationally-heavy, open-world games with good built-in benchmarks.

Ghost Recon Wildlands

We run the built-in benchmark using a 1440P and 4K resolution and the same settings as the 1080p test (Very High preset).

Grand Theft Auto V

We run the built-in benchmark using a 1440P and 4K resolution and the same settings as the 1080p test (generally Maximum quality settings including Advanced Graphics).

1440P and 4K Gaming Performance Overview:

Even with the resolutions increased, the Kaby Lake and Kaby Lake-X Core i7 CPUs maintain their positions atop the charts. If you are a high-resolution gamer, the Core i7-7740X is a good CPU for your system. However, it does not offer a noticeable performance advantage over the i7-7700K and its cheaper LGA 1151 platform.

4K60 gamers are spoilt with choice when it comes to purchasing a CPU. There’s little performance difference between all of the chips on display at this resolution where GPU horsepower is in high demand. Kaby Lake-X is up there amongst the fastest options at 4K but it isn’t necessarily the best choice if you also want to stream gameplay at the same time.
