Doom

The Intel Core Ultra 9 275HX and NVIDIA GeForce RTX 5070 combination delivers a robust Doom experience across the board, but the data reveals a clear hierarchy of performance that shifts dramatically depending on resolution and settings. At 1080p, the system is capable of triple-digit frame rates on every preset, with the Low preset reaching a measured 224 FPS average. Moving to 1440p, the average frame rates remain highly playable, ranging from 87 FPS on Ultra to 145 FPS on Low. At 4K, the system begins to show its limits, with the Ultra preset dipping to a 47 FPS average, while High and Medium presets still manage 58 and 68 FPS respectively. The measured data indicates that this mobile-class GPU and flagship-class CPU pairing is well-suited for high-refresh-rate 1080p and 1440p gaming, while 4K requires careful settings selection to maintain smooth performance.

Resolution Scaling

The performance drop from 1080p to 4K is substantial and reveals the GPU as the primary bottleneck at higher resolutions. At 1080p with the High preset, the system produces 165 FPS average. Scaling to 1440p High drops that to 107 FPS, a reduction of 58 FPS (or roughly 35%). Moving from 1440p to 4K High further reduces performance to 58 FPS, another 49 FPS drop (or approximately 46%). This pattern is consistent across all settings presets, indicating that the RTX 5070’s rendering workload grows disproportionately with pixel count.

The Low preset shows the most dramatic scaling behavior. At 1080p Low, the system hits 224 FPS average. At 1440p Low, it falls to 145 FPS, and at 4K Low, it reaches 79 FPS. The step from 1080p to 1440p represents a 79 FPS decrease, while the step from 1440p to 4K represents a 66 FPS decrease. This suggests that even at the lowest graphical settings, the GPU is still heavily taxed by the resolution increase, rather than the CPU becoming a limiting factor.

Examining the Medium preset, which includes measured minimum and maximum frame rates, provides additional insight into frame time consistency. At 4K Medium, the average FPS is 68, with a minimum of 58 and maximum of 79. The spread from minimum to maximum is 21 FPS, indicating some variability in frame delivery. At 1440p Medium, the average is 126 FPS, with minimum 107 and maximum 145, a spread of 38 FPS. At 1080p Medium, the average is 195 FPS, with minimum 166 and maximum 224, a spread of 58 FPS. The widening spread at lower resolutions suggests that CPU-side frame pacing or driver overhead becomes more variable when the GPU is less saturated, though the overall frame rates remain high.

The Ultra preset demonstrates the steepest scaling curve. At 1080p Ultra, the system achieves 135 FPS average. Dropping to 1440p Ultra yields 87 FPS, a 48 FPS reduction. At 4K Ultra, the average falls to 47 FPS, another 40 FPS reduction. This 4K Ultra result is the only measured configuration that falls below the 60 FPS threshold, making it marginal for smooth gameplay on typical 60 Hz displays.

The data points to the RTX 5070 as the limiting component at 4K, given that the Core Ultra 9 275HX has substantial headroom in synthetic benchmarks. The CPU’s Cinebench R23 multi-core score of 35589 and single-core score of 2204 place it in the 94th percentile of all CPUs, according to the benchmark database. The GPU’s 82nd percentile ranking among all GPUs, combined with its 3DMark Steel Nomad DX12 score of 5077, suggests that while capable, it is not an extreme-performance part. The resolution scaling pattern is typical for a GPU-bound scenario, where frame rate decreases almost linearly with pixel count increases.

Settings Recommendations

The measured FPS data provides clear guidance for optimizing the experience across different resolutions. At 1080p, any preset delivers playable performance, but the High preset at 165 FPS average is an excellent choice for high-refresh-rate monitors, as it substantially exceeds the 144 Hz threshold while maintaining better visual fidelity than Low or Medium. For users with 240 Hz displays, the Medium preset at 195 FPS average is a better match, offering a 30 FPS advantage over High while still looking respectable. The Low preset at 224 FPS average is only necessary for the most demanding competitive scenarios where every frame matters, but the visual compromise is significant.

At 1440p, the recommendation shifts toward balance. The High preset at 107 FPS average is ideal for 100 Hz or 120 Hz monitors, providing a smooth experience without excessive GPU load. The Medium preset at 126 FPS average offers additional headroom for 144 Hz displays, though the visual difference from High may be noticeable in texture detail and shadow quality. The Ultra preset at 87 FPS average is still playable on 60 Hz or 75 Hz displays, but the 20 FPS loss compared to High suggests that the extra graphical features are not worth the performance cost for most users. The Low preset at 145 FPS is overkill for most 1440p monitors and sacrifices too much visual quality.

At 4K, the choices are more constrained. The Medium preset at 68 FPS average is the only configuration that clears the 60 FPS bar, making it the recommended default for smooth gameplay on standard 60 Hz displays. The High preset at 58 FPS is borderline, and the 10 FPS gain from dropping to Medium is substantial enough to justify the visual downgrade. The Ultra preset at 47 FPS is not recommended, as it falls below the playability threshold for most action games, including a fast-paced FPS like Doom. The Low preset at 79 FPS is an option for users who prioritize frame rate above all else, but the visual degradation at 4K resolution is more pronounced than at lower resolutions.

For the best overall experience, the data suggests prioritizing the High preset at 1080p or 1440p, and the Medium preset at 4K. These configurations provide the highest average frame rates that still exceed 60 FPS, with the 1080p High and 1440p High options offering ample headroom for variable refresh rate displays. The measured minimum frame rates, available for the Medium preset, show that even at 4K, the system does not dip below 58 FPS, indicating reasonable frame pacing.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. The Low preset achieves 224 FPS average, which is the peak measured value for this combination. The Medium preset follows at 195 FPS average, with a minimum of 166 FPS and maximum of 224 FPS. The High preset reaches 165 FPS average, and the Ultra preset produces 135 FPS average. The progression from Low to Ultra shows a consistent reduction in frame rate, with the largest single-step drop occurring between Medium and High, a 30 FPS decrease. The step from High to Ultra is also 30 FPS, while the step from Low to Medium is 29 FPS. This linear degradation suggests that each settings tier adds a similar GPU workload at this resolution.

At 2560x1440, the frame rates remain high but show more separation between presets. The Low preset achieves 145 FPS average, which is still excellent for most displays. The Medium preset delivers 126 FPS average, with minimum 107 FPS and maximum 145 FPS. The High preset produces 107 FPS average, and the Ultra preset drops to 87 FPS average. The delta between Low and Medium is 19 FPS, between Medium and High is 19 FPS, and between High and Ultra is 20 FPS. This consistent 19-20 FPS reduction per settings tier indicates that the GPU is handling each tier’s additional workload in a predictable manner at 1440p.

At 3840x2160, the frame rates fall to the lowest measured values. The Low preset achieves 79 FPS average, which is still above 60 FPS. The Medium preset delivers 68 FPS average, with a minimum of 58 FPS and maximum of 79 FPS. The High preset produces 58 FPS average, and the Ultra preset drops to 47 FPS average. The step from Low to Medium is 11 FPS, from Medium to High is 10 FPS, and from High to Ultra is 11 FPS. The smaller absolute differences between presets at 4K compared to lower resolutions indicate that the GPU is becoming the dominant limiting factor, as each settings tier’s incremental cost is compressed by the overall resolution burden.

The Medium preset is the only one with complete minimum and maximum frame rate data across all resolutions. At 1080p, the spread between min and max is 58 FPS (166 to 224). At 1440p, the spread is 38 FPS (107 to 145). At 4K, the spread narrows to 21 FPS (58 to 79). This narrowing spread at higher resolutions suggests that frame pacing becomes more consistent when the GPU is fully utilized, whereas at lower resolutions, the CPU or driver overhead may introduce more variability in frame delivery times.

GPU Role

The NVIDIA GeForce RTX 5070 is built on the Blackwell 2.0 architecture, featuring the GB205 chip manufactured on a 5 nm process by TSMC. The GPU contains 31,100 million transistors on a 263 mm² die, resulting in a transistor density of 118.3 million per mm². The core configuration includes 6144 shading units, 192 texture mapping units, and 80 raster output units, alongside 48 ray tracing cores and 192 tensor cores. The boost clock is rated at 2512 MHz, with a base clock of 2325 MHz. The pixel rate is 201.0 GPixel/s, and the texture rate is 482.3 GTexel/s, with FP32 performance rated at 30.87 TFLOPS.

The memory subsystem is a key differentiator for this GPU. It features 12 GB of GDDR7 memory on a 192-bit bus, providing 672.0 GB/s of bandwidth. The memory clock is 1750 MHz, operating at 28 Gbps effective. This bandwidth is substantial for a mobile-class GPU and directly contributes to the resolution scaling observed in Doom. At 4K, the higher memory bandwidth requirement for textures and geometry is met, but the overall GPU compute capacity becomes the limiting factor, as evidenced by the 47 FPS average at 4K Ultra.

Synthetic benchmarks place the RTX 5070 in the 82nd percentile of all GPUs, with an average benchmark score of 40377. In 3DMark Steel Nomad DX12, it scores 5077, while Geekbench OpenCL and Vulkan scores are 172660 and 178923 respectively. Passmark G3D score is 29137, and GPU Compute score is 15787. The nearest rivals in the benchmark database include the AMD Radeon Pro 580 with an average score of 40318 (0.1% higher), the AMD Radeon Pro WX 7100 with 40063 (0.8% higher), the AMD Radeon Pro 5300 with 40870 (1.2% lower), and the NVIDIA RTX A500 Mobile with 39568 (2.0% higher). These rival comparisons indicate that the RTX 5070 sits in a competitive bracket, but none of these rivals are modern gaming GPUs, suggesting that the 5070’s gaming performance is substantially higher than these professional workstation parts.

In Doom specifically, the GPU’s role is decisive at higher resolutions. The measured data shows that at 1080p, the GPU has enough headroom to push frame rates well beyond 144 FPS on most presets, indicating that the CPU is not a limiting factor at this resolution. At 4K, the GPU becomes fully saturated, and the frame rate drops to 47-79 FPS depending on settings. The 12 GB VRAM capacity is sufficient for this game at all measured settings and resolutions, as no out-of-memory issues are indicated by the data. The GDDR7 memory type and 672.0 GB/s bandwidth provide adequate throughput for the 4K texture data, but the compute limitations of the GPU cap performance.

The CPU’s average benchmark score is 67469, placing it in the 94th percentile of all CPUs.

The nearest CPU rivals in the database are all workstation or server processors. The Intel Xeon w5-3525 has an average score of 67673, which is 0.3% higher than the Core Ultra 9 275HX. The AMD EPYC 4484PX scores 67822, 0.5% higher. The AMD Ryzen Threadripper PRO 5955WX scores 67868, 0.6% higher. The Intel Xeon 6515P scores 67006, 0.7% lower. These comparisons show that the Core Ultra 9 275HX is competitive with high-end workstation CPUs, despite being a mobile processor.

In Doom, the CPU’s role is primarily to feed the GPU with draw calls and physics calculations. At 1080p, the measured frame rates of 135-224 FPS across settings suggest that the CPU is capable of driving very high frame rates without becoming a bottleneck. The 24 cores and 24 threads provide ample parallel processing capacity, while the 5.40 GHz boost clock ensures strong single-thread performance for game logic. The 36 MB of L3 cache helps reduce memory latency for frequently accessed game data.

At 4K, the CPU’s advantage becomes less relevant, as the GPU is the limiting factor. The frame rate difference between 1080p and 4K at the same settings is primarily attributed to GPU workload, not CPU capability. The CPU’s memory bandwidth of 102.4 GB/s is sufficient for the game’s data streaming needs, even at 4K with High or Ultra settings. The dual-channel DDR5 support provides adequate throughput without causing frame rate drops that would indicate memory starvation.

The combination of the Core Ultra 9 275HX’s high single-thread performance and the RTX 5070’s mid-range GPU compute capacity creates a system where the CPU rarely limits frame rates. At 1080p Low, the 224 FPS average is likely near the CPU’s maximum achievable frame rate for this game engine, but even the Ultra preset at 135 FPS leaves headroom. At 4K, the CPU is underutilized, as the GPU’s rendering workload dominates the frame time. This balance makes the system versatile, capable of high-refresh-rate 1080p gaming and playable 4K gaming with appropriate settings adjustments.
