Gears of War E-Day is an uncharacteristically CPU-heavy Unreal Engine 5 game
Unreal Engine 5 doesn’t normally stress your CPU, but Gears of War E-Day will.

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. Most of them haven’t made the cut, simply because of a lack of scaling. We’ve tried to include games like Clair Obscur: Expedition 33, The Elder Scrolls IV: Oblivion Remastered, and Halo: Campaign Evolved, due to the prevalence of Unreal Engine 5 in modern AAA games, but the CPU scaling just doesn’t matter.
There are some exceptions, notably Marvel Rivals with its dense fighting arenas, large teams, and destructible environments, and The Blood of Dawnwalker, which has a large, sparsely populated city in the middle of the map that will bring most CPUs to their knees. Even then, however, these UE5 games don’t show the same level of scaling as other games in our test suite, such as Starfield or Baldur’s Gate 3.
Gears of War E-Day is an exception. It’s not only demanding on the CPU, easily spiking even the Ryzen 7 9800X3D to full utilization at 1080p, it also shows scaling across a wide pool of chips. And further, this is true even at the game’s Ultra preset (though not the Ludicrous preset, which we’ll dig into later). This heavy CPU burden was consistent throughout the opening hours of the game, as well, regardless of scene complexity or interactions.
If you're interested in GPU performance, make sure to check out our Gears of War E-Day GPU benchmarks, as well.
We tested Gears of War E-Day on the same test systems we use for CPU reviews, short of the GPU driver, which we changed for this benchmarking session (the game won’t launch without the Game Ready driver). Otherwise, everything is identical, down to the frozen OS images we use across AMD and Intel test systems.
As usual, we tested with the RTX 5090 Founders Edition at 1080p to showcase the differences between each CPU. We ran a handful of chips at 1440p, as well, to get an idea of how performance scales at a higher resolution. We omitted 4K, as our graphics analysis of the game showed that it was completely GPU-bound at that high of a resolution. Go figure.
