GPU Role

The AMD Radeon RX 6750 XT is the primary driver of frame rate in Doom, especially as resolution increases. Built on the RDNA 2.0 architecture with the Navi 22 chip, the GPU operates at a base clock of 2150 MHz and a boost clock of 2600 MHz, with a game clock of 2495 MHz. The 12 GB of GDDR6 memory on a 192-bit bus delivers 432.0 GB/s of bandwidth, which proves sufficient for the textures and assets in Doom at all tested settings. The GPU's 2560 shading units and 64 ROPs handle the game's rendering workload, and its 40 ray accelerators provide hardware support for advanced lighting effects, though Doom's primary rendering path relies more heavily on traditional rasterization.

The GPU's performance metrics show a clear hierarchy across settings. At 4K, the average frame rate drops from 85 FPS on Low to 74 FPS on Medium, 62 FPS on High, and 51 FPS on Ultra. This 40% reduction from Low to Ultra demonstrates the significant load increase placed on the GPU as visual fidelity rises. The GPU's 13.31 TFLOPS of FP32 compute and 416.0 GTexel/s texture rate allow it to maintain playable frame rates even at the demanding 4K Ultra preset, though the 51 FPS average falls just below the 60 FPS threshold. The GPU's 166.4 GPixel/s pixel rate is a key factor in its ability to push high-resolution frames, and the benchmark results indicate that the RX 6750 XT is the limiting component at 4K, as the CPU has ample headroom to feed it frames.

Measured FPS Breakdown

The measured frame rates provide a complete picture of performance across three resolutions and four settings presets. At 1920x1080, the combo produces an average of 242 FPS on Low settings, which drops to 210 FPS on Medium, 178 FPS on High, and 145 FPS on Ultra. The Medium preset records a minimum of 179 FPS and a maximum of 242 FPS, showing a tight frame time distribution. These numbers indicate that the system is heavily GPU-bound at 1080p, as even the Ultra preset maintains a frame rate far above the refresh rate of most monitors.

Moving to 2560x1440, the average frame rates decline proportionally. The Low preset achieves 156 FPS, Medium averages 136 FPS (with a minimum of 116 and maximum of 157), High produces 115 FPS, and Ultra drops to 94 FPS. The scaling from 1080p to 1440p shows a reduction of approximately 35% across all settings, which aligns with the increased pixel count. At 1440p, the combo still comfortably exceeds 90 FPS even at Ultra settings, making this resolution the sweet spot for high-refresh-rate gaming.

At 3840x2160, the frame rates reflect the GPU's limitations. Low settings yield an average of 85 FPS, Medium drops to 74 FPS (minimum 63, maximum 85), High averages 62 FPS, and Ultra falls to 51 FPS. The transition from 1440p to 4K results in another significant drop, with the Ultra preset losing 46% of its performance. The High preset at 4K just manages to clear the 60 FPS threshold, while Ultra falls below it. The measured data shows that the system is capable of 4K gaming, but only with settings adjustments to maintain smooth frame rates.

Resolution Scaling

The performance scaling from 1080p to 4K reveals important insights about the bottleneck in this system. At 1080p with Ultra settings, the combo averages 145 FPS. When resolution increases to 1440p, the average drops to 94 FPS, a 35% reduction. Moving from 1440p to 4K, the Ultra preset falls to 51 FPS, another 46% reduction. The cumulative drop from 1080p to 4K at Ultra settings is 65%, which is slightly less than the theoretical 75% pixel count increase, suggesting that the CPU provides some headroom that gets consumed at higher resolutions.

The scaling pattern is consistent across all settings presets, indicating that the GPU is the primary limiting factor. At Low settings, the frame rate drops from 242 FPS at 1080p to 156 FPS at 1440p (36% reduction) and then to 85 FPS at 4K (45% reduction from 1440p). The High preset shows a similar trend: 178 FPS at 1080p, 115 FPS at 1440p (35% drop), and 62 FPS at 4K (46% drop). This uniform scaling behavior confirms that the RX 6750 XT's rendering throughput is the determining factor, and the CPU's performance does not introduce a bottleneck until frame rates approach the very high 200+ FPS range at 1080p Low.

The data suggests that the Intel Core Ultra 5 225 has sufficient single-thread performance to keep up with the GPU at most settings. The CPU's boost clock of 4.90 GHz and strong Cinebench R23 single-core score of 3655 provide the necessary instruction throughput for Doom's game logic and draw call processing. However, at 1080p with Low settings, the 242 FPS average approaches the point where CPU overhead could begin to limit performance, even though the measured data does not show a plateau.

CPU Role

The Intel Core Ultra 5 225 provides the computational foundation for this combination. With 10 cores and 10 threads, the processor operates at a base clock of 3.30 GHz and boosts up to 4.90 GHz. The 20 MB of shared L3 cache and 3 MB per-core L2 cache help reduce memory latency, while the 102.4 GB/s dual-channel DDR5 memory bandwidth ensures data flows efficiently to the GPU. The CPU's 85th percentile ranking among all processors indicates strong overall performance, and its benchmark scores confirm this: Cinebench R23 multi-core reaches 25891, while the single-core score is 3655.

In Doom, the CPU's role is primarily to manage game logic, physics, and draw calls. The PassMark physics score of 2342 and the integer math score of 65345 reflect the processor's ability to handle these workloads. The CPU's single-thread performance is particularly important for Doom's engine, and the PassMark single-thread score of 4412 demonstrates that it can keep pace with the GPU at most settings. The nearest rival CPUs—the AMD Ryzen 5 5600F, AMD Ryzen 5 5500X3D, AMD Ryzen AI 7 PRO 450, and Intel Core i9-12900T—all perform within 0.5% of the Core Ultra 5 225, meaning the choice between these processors would have negligible impact on Doom's frame rates.

The CPU's influence on performance is most evident at 1080p with lower settings, where frame rates exceed 200 FPS. At these high frame rates, the CPU must process frames quickly enough to keep the GPU fed. The measured data shows that the combo achieves 242 FPS at 1080p Low, which indicates the CPU can handle the workload at that level. However, the CPU's multi-threaded performance, while strong, does not provide a significant advantage in Doom, as the game's engine is not heavily threaded. The 10-core, 10-thread configuration without hyper-threading is sufficient for this title, and the CPU does not appear to bottleneck the GPU at any tested resolution or setting.

Settings Recommendations

Based on the measured frame rates, the optimal settings depend on the target resolution and desired frame rate. At 1920x1080, all settings provide excellent performance, with even the Ultra preset averaging 145 FPS. For gamers with a 144 Hz or 165 Hz monitor, the High preset at 178 FPS is the best choice, as it provides a substantial frame rate buffer above the refresh rate while maintaining high visual quality. The Medium preset at 210 FPS is ideal for competitive play where maximum frame rates matter, though the visual difference between Medium and High is noticeable in Doom's detailed environments.

At 2560x1440, the High preset delivers 115 FPS, which is well-suited for 120 Hz displays. The Ultra preset at 94 FPS remains smooth on 100 Hz monitors and provides the best visual fidelity. The Medium preset at 136 FPS offers the best balance for high-refresh-rate 1440p gaming, as it stays above 120 FPS while still looking polished. The Low preset at 156 FPS is unnecessary at this resolution, as the visual compromises do not justify the frame rate increase when High is already playable.

At 3840x2160, the settings selection becomes more critical. The High preset at 62 FPS is the recommended choice, as it just clears the 60 FPS threshold and provides the best visual quality among playable options. The Medium preset at 74 FPS offers a smoother experience with a 19% frame rate increase, making it the best option for gamers who prioritize frame pacing over visual details. The Ultra preset at 51 FPS falls below 60 FPS and may feel less responsive, while the Low preset at 85 FPS sacrifices too much visual quality for the resolution. For 4K gaming, the Medium preset provides the most consistent experience, with a minimum recorded frame rate of 63 FPS ensuring no drops below the 60 FPS threshold.
