Doom

The Intel Core Ultra 5 245 and NVIDIA GeForce RTX 5080 combination delivers exceptional performance in Doom, a title from 2016 that remains extremely playable at the highest settings. The data shows a system capable of dramatically high frame rates across all tested resolutions, with the primary bottleneck shifting from the GPU at 4K to the CPU at 1080p. This analysis breaks down the measured results to explain how the hardware components interact with the game’s engine.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly illustrates the changing workload on the system. At 1920x1080 with Low settings, the combo produces an average of 416 FPS. Moving to 2560x1440 at Low settings drops the average to 269 FPS, a 35% reduction. At 3840x2160 with Low settings, the average falls further to 146 FPS, which is a 46% reduction from the 1440p figure and a 65% reduction from the 1080p result. This steep decline at lower settings indicates that the GPU is being increasingly taxed as pixel count rises, but the CPU is still keeping pace.

The scaling pattern changes when looking at Ultra settings. At 1080p Ultra, the average is 250 FPS. At 1440p Ultra, it drops to 162 FPS, a 35% decrease. At 4K Ultra, the average falls to 88 FPS, a 46% decrease from 1440p. The consistent percentage drops between resolutions at both Low and Ultra presets suggest a balanced system, but the absolute numbers reveal the limiting factor. At 1080p Low, the 416 FPS average is extraordinarily high, and the jump from 306 FPS at 1080p High to 416 FPS at 1080p Low shows that the CPU is capable of feeding the GPU well beyond typical display refresh rates. The data suggests that at 1080p, the game engine’s draw call overhead and single-thread performance are the primary constraints, as the RTX 5080 is not being fully utilized.

At 4K, the situation inverts. The difference between Low (146 FPS) and Ultra (88 FPS) is 58 FPS, a 40% performance hit purely from raising graphical quality. This gap is significantly larger than the 1080p gap between Low (416 FPS) and Ultra (250 FPS), which is a 40% difference as well, but the absolute frame rates are much lower at 4K. The 4K results indicate the GPU is now the dominant bottleneck, with the pixel fill rate and shading workload of the RTX 5080 determining the final output. The RTX 5080’s 112 ROPs and 56.28 TFLOPS of FP32 performance are being pushed hard at this resolution, and the scaling shows that the card’s raw compute power is the deciding factor for high-fidelity 4K gameplay.

How This Combo Ranks

In the benchmark database, this specific CPU and GPU pairing ranks 147th out of 2930 tested combinations for Doom. This places the combo in the top 5% of all tested systems, a position that reflects the high-end nature of both components. The combination of a 14-core Intel Core Ultra 5 245 and the RTX 5080 is clearly a formidable pairing for this title, as the rank demonstrates that it outperforms the vast majority of other hardware configurations. The percentile ranking of the CPU itself is 90, meaning it performs better than 90% of all CPUs tested on the site. The GPU’s percentile is 87, indicating it is also in the top 13% of all graphics cards.

The combo’s rank is a function of both components’ strengths. The CPU’s high single-core performance, evidenced by its Cinebench R23 single-core score of 4648, is critical for Doom’s engine, which relies heavily on a few fast cores for game logic and draw call submission. The GPU’s massive compute throughput, with a Passmark G3D score of 36565, ensures that the rendering pipeline is never starved. While the combo does not reach the top 100, its position at 147 out of 2930 is a strong indicator of a system that will not struggle to maintain high frame rates in this game. The data shows that this pairing is significantly more powerful than the average system, and the rank reflects the synergy between the Ultra 5’s high clock speeds and the RTX 5080’s immense shading power.

GPU Role

The NVIDIA GeForce RTX 5080 is the primary driver of graphical performance in this system. It is built on the Blackwell 2.0 architecture and features 10752 shading units, 336 texture mapping units, and 112 ROPs. The card operates at a base clock of 2295 MHz and boosts to 2617 MHz. This high clock speed, combined with the massive number of cores, allows the GPU to process the complex lighting and particle effects in Doom with ease. The GPU’s memory configuration includes 16 GB of GDDR7 memory on a 256-bit bus, providing a bandwidth of 960.0 GB/s. This high bandwidth is essential for feeding the shaders at 4K resolution with high-resolution textures.

The GPU’s role is most evident in the Ultra preset results. At 4K Ultra, the average frame rate drops to 88 FPS, while at 1080p Ultra, it reaches 250 FPS. The 162 FPS difference shows that the GPU’s compute and memory bandwidth are being saturated at higher resolutions. The card’s FP32 performance of 56.28 TFLOPS is a theoretical peak, and the measured results show that in practice, the card is able to sustain high throughput. The texture rate of 879.3 GTexel/s and pixel rate of 293.1 GPixel/s are directly related to the fill rate demands of the game. In comparison to its nearest rivals, the RTX 5080 has an average benchmark score of 56083, which is 0.6% higher than the AMD Radeon 8060S and 0.7% higher than the AMD Radeon RX 6750 GRE 12 GB. It trails the AMD Radeon RX 9070 GRE by 2.2%. These small percentage differences in synthetic benchmarks translate to the measured FPS results, where the RTX 5080’s raw power is the deciding factor in the 4K Ultra setting, where it produces 88 FPS, a number that is still very playable but significantly lower than the lower resolution results.

Measured FPS Breakdown

At 1920x1080, the system produces staggering frame rates. With Low settings, the average FPS is 416. Moving to Medium settings, the average drops to 363 FPS, with a minimum of 308 and a maximum of 417. High settings yield an average of 306 FPS. Ultra settings at 1080p still produce an average of 250 FPS. These numbers indicate that at 1080p, the game is heavily CPU-limited, as the GPU is capable of far more than the engine can request. The difference between Low and Ultra is 166 FPS, showing the graphical settings have a significant impact, but the absolute values are so high that all presets are playable on high refresh rate monitors.

At 2560x1440, the frame rates remain exceptionally high. Low settings produce an average of 269 FPS. Medium settings average 235 FPS, with a minimum of 199 and a maximum of 270. High settings average 198 FPS. Ultra settings at 1440p average 162 FPS. The scaling here is more consistent, with the GPU beginning to take on a larger workload. The 1440p results show a 40% drop from Low to Ultra in absolute terms, similar to the 1080p drop, but the system is still delivering well over 160 FPS on the highest preset, making it an ideal resolution for high refresh rate gaming.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings average 146 FPS, which is a significant drop from the 1440p Low result of 269 FPS. Medium settings average 127 FPS, with a minimum of 108 and a maximum of 146. High settings average 107 FPS. Ultra settings at 4K produce an average of 88 FPS. The 4K Ultra result is the only one below the 100 FPS mark, but it is still a very smooth experience. The data shows that the system is capable of 4K gaming at the highest settings, though users seeking higher frame rates may prefer to use the High preset, which offers a 19 FPS increase over Ultra.

CPU Role

The Intel Core Ultra 5 245 is a 14-core, 14-thread processor based on the Arrow Lake architecture. It has a base clock of 3.50 GHz and a boost clock of 5.10 GHz. The high boost clock is critical for Doom, which is a game that benefits from strong single-thread performance. The CPU’s Cinebench R23 single-core score of 4648 confirms its strength in this area. The processor also has 24 MB of shared L3 cache, which helps reduce latency for frequently accessed game data. The CPU’s 14 cores are more than sufficient for Doom, which is not a highly threaded title, but the high clock speeds ensure that the main game thread is never a bottleneck.

The CPU’s role is most apparent at 1080p, where the GPU is not fully utilized. The jump from 306 FPS at High settings to 416 FPS at Low settings shows that the CPU is capable of pushing frame rates far beyond what the GPU can render at higher settings. The CPU’s Passmark single-thread score of 4394 and its Cinebench R15 single-core score of 468 indicate that it has excellent per-core performance. In the benchmark database, the CPU has an average benchmark score of 48995, which is only 0.4% lower than the AMD Ryzen 7 PRO 5755G and 0.5% lower than the AMD Ryzen 9 7900. It is 0.6% higher than the Intel Xeon Gold 5318H and 0.8% higher than the Intel Core i5-14600K. These close scores show that the Ultra 5 245 is a top-tier performer for gaming workloads. The data suggests that the CPU will not be the limiting factor for Doom at any resolution, as its high clock speeds and efficient architecture provide more than enough processing power to feed the RTX 5080.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings. At 1920x1080, the Ultra preset is the best choice, as it delivers an average of 250 FPS, which is well above the refresh rate of even the fastest gaming monitors. The jump from High to Ultra only costs 56 FPS, but the visual fidelity improvements are worth it. The system has so much headroom at this resolution that there is no reason to lower settings.

At 2560x1440, the Ultra preset is also recommended, delivering an average of 162 FPS. This is still high enough for 144Hz and 165Hz monitors, and the visual quality is maximized. If a user has a 240Hz monitor, they may consider the High preset, which averages 198 FPS, a 36 FPS increase. The data shows that the Medium preset, with an average of 235 FPS, is the best option for users who prioritize frame rate above all else at this resolution.

At 3840x2160, the choice is more nuanced. The Ultra preset averages 88 FPS, which is playable on a 60Hz or 90Hz display but may feel less smooth on a 120Hz panel. The High preset averages 107 FPS, which is a significant improvement and is the recommended setting for 4K gaming. It offers a 19 FPS increase over Ultra while likely providing a similar visual experience. The Medium preset averages 127 FPS, which is ideal for 120Hz 4K displays. The Low preset at 146 FPS is only recommended for competitive play where frame rate is the absolute priority, but the visual quality loss is substantial. For most users, the High preset at 4K offers the best balance of visual fidelity and performance, ensuring a smooth experience without sacrificing the graphical enhancements that make Doom look great.
