High settings deliver 62 FPS average, Low settings reach 85 FPS average, and Ultra settings produce 51 FPS average. The 4K Ultra result of 51 FPS is just below the 60 FPS threshold typically considered optimal for smooth gameplay, while 4K High at 62 FPS is playable but not ideal for high-refresh-rate monitors.

Settings Recommendations

For 4K gameplay, the data suggests that Medium settings provide the best balance of visual quality and performance. The 74 FPS average with a 63 FPS minimum ensures consistent frame delivery, while High settings at 62 FPS average are also viable. Ultra settings at 51 FPS average should be avoided for competitive play, as the frame rate dips below the 60 FPS threshold. Low settings at 85 FPS average offer the highest frame rates but sacrifice significant visual fidelity.

At 1440p, Ultra settings are the clear recommendation for most players. The 94 FPS average is well above the 60 FPS threshold, and the visual quality improvement over High settings (115 FPS) is substantial. Players with 144Hz monitors may prefer High settings to maximize frame rates, but the Ultra preset remains playable and visually superior. Medium settings at 136 FPS provide a middle ground for those seeking higher refresh rates, while Low settings at 156 FPS are only recommended for competitive play.

For 1080p, the choice depends on the monitor's refresh rate. Ultra settings at 145 FPS average are suitable for 144Hz displays, while High settings at 178 FPS can drive 165Hz monitors. Medium settings at 210 FPS average are ideal for 240Hz displays, and Low settings at 242 FPS effectively max out most refresh rates. The data shows that even at Ultra settings, the combo maintains a 145 FPS average, making 1080p Ultra the best overall experience for most users.

CPU Role

The Intel Core Ultra 7 270K Plus features 24 cores and 24 threads, operating at a base clock of 3.70 GHz with a boost clock of 5.50 GHz. This configuration is unusual — typically, CPUs with 24 threads have 12 cores with hyperthreading, but this part offers 24 physical cores. The CPU's cache hierarchy includes 192 KB of L1 cache per core, 3 MB of L2 cache per core, and 36 MB of shared L3 cache, providing substantial fast memory for game data.

In Doom, which was released in 2016, the CPU's role is primarily to handle game logic, physics, and draw calls. The game's id Tech 6 engine is known for being well-optimized for multi-core processors, and the 24 physical cores provide ample parallel processing capability. The CPU's single-thread performance, evidenced by its Cinebench R23 single-core score of 2439, is particularly important for maintaining high frame rates in scenes with complex AI or particle effects.

The CPU's benchmark results show strong multi-threaded performance, with a Cinebench R23 multi-core score of 44253 and a Passmark multithread score of 68574. Its Passmark single-thread score of 5068 places it in the 96th percentile of all CPUs, indicating that its per-core performance is among the best available. This is crucial for Doom, as the game's rendering pipeline can be bottlenecked by single-threaded tasks, especially at lower resolutions where the GPU is not the limiting factor.

Resolution Scaling

The measured FPS data reveals how the combo scales from 1080p to 4K, providing insights into the system's bottleneck. At Low settings, the average frame rate drops from 242 FPS at 1080p to 156 FPS at 1440p (a 35.5% decrease) and further to 85 FPS at 4K (a 64.9% decrease from 1080p). This dramatic scaling indicates that the GPU is the primary limiting factor, as the CPU can easily maintain high frame rates even at 4K.

At Medium settings, the scaling is similar: 210 FPS at 1080p drops to 136 FPS at 1440p (35.2% decrease) and 74 FPS at 4K (64.8% decrease). The consistency of these percentage drops across settings suggests that the GPU's compute and memory bandwidth are being fully utilized at all resolutions. The CPU shows no signs of bottlenecking, as the frame rate scaling follows the expected pattern for a GPU-bound workload.

The transition from 1440p to 4K shows the most significant performance impact. At High settings, the average drops from 115 FPS to 62 FPS, a 46.1% decrease. This steep decline indicates that the 12 GB VRAM and 432.0 GB/s bandwidth are being stressed at 4K, particularly with higher texture quality settings. The GPU's 2560 shading units are also being taxed, as the 4K Ultra result of 51 FPS suggests the card is approaching its rendering limits. The data implies that the RX 6750 XT is best suited for 1440p gaming, where it can maintain high frame rates across all settings, while 4K gaming requires compromises in visual quality to achieve playable performance.
