Far Cry Primal's Dunia Engine 2 responds well to high clock rates and IPC throughput. However, it also seems to prefer when we turn off simultaneous multi-threading, so you'll notice the Core i5 processors are very competitive.

We do see a bit more frame time variance between certain models, but the lead again shuffles back and forth between patched and unpatched configurations. That means we can chalk these differences up to expected variances.

Typically, our reviews include similarly-priced models, so the floors and ceilings aren't so pronounced. Today's exploration gives us a good opportunity to see how different CPU classes scale. For instance, the average frame rate delta between Intel's Pentium G4560 and Core i7-7700K is 27 FPS.

The Grand Theft Auto V benchmark again reveals little variance between configurations, and a negligible impact on frame times.

We do spot several notable outliers from Intel's Core i3-8350K, but those occur whether the CPU is patched or not. We also record a 42 FPS 99th percentile measurement with the patched Core i3-7350K compared to the unpatched configuration's 47 FPS. That's one of the largest deltas reported in today's data.

Hitman (2016)

We're graphics-bound in our Hitman test, so there is little to no variation between the Core i7 and i5 processors.
