Intel Core i5 versus i7 processors – which is better for gaming?

AMD Zen to reach high-end desktops by the end of 2016

Most PC gamers with high-end in South Africa use Intel Core i5 or i7 processors for modern gaming, as most modern triple-A titles require a 4-core CPU to run optimally.

However, it is uncertain whether games benefit enough from an equivalent Core i7 processor to warrant the increase in price.

We’ve compared Core i5 and Core i7 gaming benchmarks in order to determine the real difference between four and eight-thread gaming.

Benchmarks conducted a series of benchmarks testing the performance difference between Core i5 and Core i7 processors, check them out below:

The results of these benchmark comparisons display a performance deficit that mostly depends on the game being played.

This makes sense, as different games offload different amounts of physics processing to the CPU – as seen above by the Core i7’s increased performance in Crysis 3.

This phenomenon is even more apparent in newer, more processor-intensive titles such as Fallout 4. Check out the GamersNexus CPU benchmarks for Fallout 4 below:

Although high-end PC gamers are still better off investing in a top-of-the-range graphics card than upgrading to a Core i7 processor, the eight-thread CPU does have its advantages.

Specifically, a Core i7 processor allows gamers to enjoy better performance on physics-focussed games in addition to newer titles.

This performance boost is not as significant as a graphics card upgrade, although it could remove a performance bottleneck in some cases.

With PC gaming pushing the boundaries of gaming hardware, it is only a matter of time before more advanced processors are required for gamers to enjoy new technologies such as virtual reality.
