Excerpt: The opening of an article from Tom’s Hardware. Read the original for the full story.
Unreal Engine 5 isn’t particularly heavy on the CPU, but Gears of War E-Day changes that narrative. If you have a monitoring overlay open when you load into the game, you’ll immediately notice your CPU pinned at between 80% and 90% utilization, which is a far cry from most other UE5 titles. Even stranger is that the scaling between CPUs is clear. For instance, the Ryzen 7 9800X3D netted 42% higher performance than the Ryzen 5 7600X at 1080p with the High graphics preset.
We’ve tested a lot of UE5 games with our pool of CPUs to evaluate them, not only for our rankings of the best CPUs for gaming , but also for our ongoing CPU benchmark hierarchy .
