Doom

The data for Doom with the Intel Core Ultra 5 235 and NVIDIA GeForce RTX 5080 presents a fascinating study in bottleneck dynamics. This pairing of a 14-core Arrow Lake processor and a Blackwell-architecture GPU produces frame rates that span from the exceptionally high to the merely excellent, depending on the resolution and settings. The measured FPS rows reveal a clear narrative about where the performance ceiling lies and how each component contributes to the final experience.

Resolution Scaling

The measured FPS data shows a dramatic and predictable decline as resolution increases, but the rate of that decline tells a compelling story about system balance. At 1080p with Low settings, the combo produces a staggering 416 FPS average. Moving to 1440p Low drops this to 269 FPS, a 35% reduction. Continuing to 4K Low yields 146 FPS, which is another 46% drop from the 1440p figure. This steep scaling curve indicates that at lower resolutions, the system is heavily CPU-bound; the RTX 5080 has ample headroom to render frames far faster than the processor can feed it.

The trend continues across all settings presets, but the shape of the curve changes subtly. At High settings, the 1080p average is 306 FPS, which falls to 198 FPS at 1440p (a 35% drop) and then to 107 FPS at 4K (a 46% drop from 1440p). This consistent pattern of roughly a one-third reduction from 1080p to 1440p and another near-half reduction from 1440p to 4K suggests that the GPU begins to take on a more significant role as pixel count increases, yet the CPU remains a limiting factor even at 4K.

The most telling evidence of the CPU's influence is the difference between settings at each resolution. At 1080p, the spread between Low (416 FPS) and Ultra (250 FPS) is 166 FPS. At 4K, that same Low-to-Ultra spread narrows to just 58 FPS (146 vs 88). This compression of the settings gap at higher resolutions is a classic sign of a GPU bottleneck emerging. The data implies that at 1080p, the RTX 5080 is so powerful that it can execute even the Ultra preset's workload faster than the CPU can issue draw calls, making the graphics settings almost irrelevant to the final frame rate. At 4K, the GPU's rendering workload becomes the primary constraint, and the CPU's influence wanes.

Looking at the Medium preset frames, which include min/max data, provides further insight. At 4K Medium, the average is 127 FPS with a minimum of 108 and a maximum of 146. At 1440p Medium, the average jumps to 235 FPS with a minimum of 199 and a maximum of 270. The 1080p Medium row shows a 363 FPS average with a 308 minimum and 417 maximum. The minimum frame rates scale proportionally with the averages, suggesting a stable performance profile without severe hitches. However, the fact that the 4K Medium maximum of 146 FPS is lower than the 1080p Medium minimum of 308 FPS underscores how much headroom is lost as the GPU becomes the center of attention.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process. It operates with a base clock of 3.40 GHz and a boost clock of 5.00 GHz. Its 24 MB of shared L3 cache and dual-channel DDR5 memory support provide the foundation for its performance. The benchmark data indicates this is a capable processor, sitting in the 89th percentile of all CPUs, with an average benchmark score of 46062.

The CPU's influence in Doom is most apparent at lower resolutions. The data strongly suggests that at 1080p, the processor is the primary bottleneck. The evidence is the relatively small performance gap between the Low and Ultra presets at this resolution. When the GPU can render frames at 416 FPS on Low settings but only 250 FPS on Ultra, it suggests that the CPU's ability to process game logic and issue draw calls is the limiting factor, not the GPU's raw rendering power. This is further supported by the fact that the 1080p Medium average of 363 FPS is only 53 FPS lower than the Low preset's 416 FPS.

This processor's single-thread performance, as evidenced by a Cinebench R23 single-core score of 2085, is likely crucial for Doom's game logic. The game's engine doesn't appear to scale perfectly with the 14 available cores, as the multi-core score of 14769 in Cinebench R23 doesn't translate into a linear FPS advantage. Instead, the high boost clock of 5.00 GHz and the architecture's efficiency are probably the key factors in maintaining high frame rates. The data indicates that the CPU is powerful enough to keep up with the RTX 5080 at 1440p to a degree, but its performance ceiling is clearly visible when paired with such a high-end GPU.

The nearest rivals for this CPU in terms of average benchmark score are the AMD Ryzen AI 9 HX 375 and the Intel Core i9-13900HX, with delta percentages of 0.1% and -0.1% respectively. This places the Ultra 5 235 in a competitive position, but its performance in Doom is ultimately dictated by the game's engine and how well it utilizes the CPU's resources.

How This Combo Ranks

In the grand scheme of tested hardware, this pairing of the Intel Core Ultra 5 235 and NVIDIA GeForce RTX 5080 achieves a combo rank of 147 out of 2930 total combinations in Doom. This places it in the top 5% of all tested systems, which is a strong result for a high-end desktop configuration. The ranking reflects not just the GPU's power but the ability of the CPU to feed it effectively.

The fact that this combo ranks so highly despite being potentially CPU-bound at 1080p suggests that the overall performance is still excellent. The ranking is likely influenced by the 4K and 1440p results, where the RTX 5080's power is more fully utilized. A system with a weaker CPU might fall behind at 1080p, but this Ultra 5 235 provides enough single-thread performance to keep the frame rates high. The data indicates that the combo is well-balanced for high-resolution gaming, even if it leaves some performance on the table at lower resolutions.

This rank of 147 becomes more impressive when considering the number of combinations tested. With 2930 total combos, the top 147 positions represent the elite tier of gaming performance. The system's ability to maintain over 100 FPS at 4K High settings (107 FPS) confirms the GPU's power, while the 1080p results show that the CPU is not a weak link. The data suggests this is a configuration built for high-refresh-rate 1440p gaming and smooth 4K experiences, and the rank confirms its place among the best.

GPU Role

The NVIDIA GeForce RTX 5080 is the star of the show for raw rendering power. Built on the Blackwell 2.0 architecture with a 5 nm process, it features 10752 shading units, 336 texture mapping units, and 112 raster output units. It comes equipped with 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 960.0 GB/s. Its boost clock is rated at 2617 MHz, and it achieves a FP32 performance of 56.28 TFLOPS. The GPU sits in the 87th percentile of all GPUs, with an average benchmark score of 56083.

The GPU's role in Doom is to provide the massive frame rates that the CPU can't always take advantage of. At 4K, the GPU becomes the dominant factor. The difference between the Low preset (146 FPS) and Ultra preset (88 FPS) at 4K is 58 FPS, showing that the GPU's workload is significant at this resolution. The RTX 5080's 16 GB of VRAM is likely not a limiting factor in this 2016 title, even at 4K with Ultra settings. The memory bandwidth of 960.0 GB/s ensures that texture streaming and geometry processing are not bottlenecks.

The GPU's performance relative to its nearest rivals in the benchmark database is interesting. The AMD Radeon RX 9070 GRE has an average score that is 2.2% higher, while the AMD Radeon 8060S and Radeon RX 6750 GRE 12 GB have scores that are 0.6% and 0.7% lower, respectively. This suggests that in synthetic benchmarks, these cards are closely matched. However, in Doom, the RTX 5080's architectural advantages and driver optimizations likely contribute to the high frame rates seen in the measured data. The GPU's ability to achieve 107 FPS at 4K High is a clear demonstration of its high-end status.

Measured FPS Breakdown

The complete dataset provides a comprehensive view of the combo's performance across all tested configurations. At 1920x1080, the results show the CPU's dominance. The Low preset leads with 416 FPS average. The Medium preset follows at 363 FPS, with a minimum of 308 and a maximum of 417. High settings produce 306 FPS, and the Ultra preset rounds out the field at 250 FPS. This 166 FPS spread from Low to Ultra indicates that the CPU is the limiting factor, as the GPU is capable of more.

Moving to 2560x1440, the GPU begins to flex its muscles. The Low preset still leads with 269 FPS, but the Medium preset drops to 235 FPS (min 199, max 270). High settings yield 198 FPS, and Ultra settings produce 162 FPS. The spread from Low to Ultra here is 107 FPS, which is narrower than at 1080p, suggesting the GPU is becoming more involved. The 1440p results are likely the sweet spot for this combo, offering high frame rates that exceed the refresh rate of most monitors.

At 3840x2160, the GPU's workload is the primary constraint. The Low preset averages 146 FPS. The Medium preset averages 127 FPS, with a minimum of 108 and a maximum of 146. High settings drop to 107 FPS, and the Ultra preset bottoms out at 88 FPS. The spread from Low to Ultra is now just 58 FPS, confirming the GPU bottleneck. Even at 4K Ultra, the system maintains a playable 88 FPS, which is a strong result for a demanding resolution.

Settings Recommendations

The measured data provides clear guidance on which settings preset offers the best experience for different priorities. For players targeting the highest possible frame rates, particularly for competitive play on high-refresh-rate 1440p monitors, the Low preset at 2560x1440 is the standout choice. It delivers a 269 FPS average, which is more than enough for any 240Hz or even 360Hz display. The jump from 1080p Low (416 FPS) to 1440p Low (269 FPS) is significant, but the visual fidelity improvement is worth the frame rate trade-off for many users.

For a balanced experience that prioritizes visual quality without sacrificing smoothness, the High preset at 2560x1440 is the recommended configuration. The 198 FPS average at this setting is still exceptionally high, and the visual upgrade from Low or Medium is substantial. This combination offers the best of both worlds: high detail and frame rates that are well above the 144Hz threshold that most gaming monitors support. The 4K High setting, which produces 107 FPS, is also viable for users with 4K displays who prefer higher fidelity over maximum refresh rates.

The Ultra preset is best reserved for 4K gaming where visual quality is the absolute priority. The 88 FPS average at 3840x2160 Ultra is smooth enough for most single-player experiences, and the game's fast-paced action will still feel responsive. At 1080p, the Ultra preset's 250 FPS is a waste of the GPU's potential, as the CPU is the limiting factor. The data suggests that the most effective use of this hardware is to play at 1440p with High or Ultra settings, or to push for maximum frame rates at 1080p with lower settings. The Medium preset at any resolution serves as a middle ground, but the High preset at 1440p offers the most compelling balance of performance and image quality based on the measured rows.
