Doom

The AMD Ryzen 7 5700X paired with the Intel Arc B370 in Doom presents a study in extremes, where a strong 8-core processor is coupled with an entry-level integrated graphics solution. The data shows a combination that is heavily constrained by the GPU at every resolution and setting tested. This analysis walks through the CPU and GPU roles, optimal settings, and the measured performance deltas that define this system.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 7 5700X is a Zen 3 (Vermeer) architecture processor built on a 7 nm process. It provides 8 cores and 16 threads, running at a base clock of 3.40 GHz and a boost clock of 4.60 GHz. This configuration is a capable modern desktop CPU, evidenced by its 79th percentile ranking against all CPUs in the benchmark database. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and a 32 MB shared L3 cache, which is ample for gaming workloads.

In the context of Doom, the CPU’s role is to feed the rendering pipeline. The 3DMark benchmark scores for the 5700X show strong scaling from single-threaded to multi-threaded workloads. For instance, the 3DMark 2-thread score is 1821, while the 8-thread score jumps to 5768, and the max-thread score reaches 6850. This indicates that the processor can efficiently handle the game’s threading demands, ensuring that the game logic, physics, and draw calls are processed quickly.

However, the measured frame rates in Doom tell a different story. At 1080p with Low settings, the combo achieves 96 FPS. As the resolution increases to 1440p and 4K, the average FPS drops to 62 and 34, respectively, at the same Low settings. This pronounced decline with resolution is a classic sign that the processor is not the limiting factor. If the CPU were the bottleneck, the frame rates would remain relatively flat across resolutions, as the CPU's workload (game logic, AI) does not scale with pixel count. The fact that the FPS falls by over 60% from 1080p to 4K at Low settings indicates that the GPU is saturated and the CPU is waiting for it to finish rendering each frame.

The 5700X’s single-thread performance, with a Geekbench single-core score of 2016 and a 3DMark single-thread score of 921, is more than sufficient for a 2016-era title like Doom. The processor is effectively idling relative to the GPU's workload in this configuration. The data suggests that this CPU could support much higher frame rates if paired with a more powerful graphics solution, as its multi-threaded capabilities (Cinebench R23 multi-core score of 13184) are far beyond what is needed to sustain the frame rates observed here. Therefore, the CPU role in this combo is to provide a stable, unhindered foundation; it is not the constraining component in any measured scenario.

GPU Role — VRAM, clocks, and how they relate to this game's results

The Intel Arc B370 is the decisive factor in this system's performance. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, built on a 3 nm process. Its specifications are modest: it features 1280 shading units, 40 texture mapping units, and 20 raster output pipelines. The clock speeds are listed with a base of 300 MHz and a boost of 2400 MHz. Critically, its memory configuration is "System Shared," meaning it uses a portion of the system's main DDR4 memory rather than dedicated VRAM. The bandwidth is listed as "System Dependent," which often results in lower performance than dedicated graphics memory.

This GPU's benchmark results are extremely low. It has a percentile rank of just 5th against all GPUs, and its only listed benchmark, 3DMark Steel Nomad DX12, scores 1184 points. Its nearest rivals include legacy cards like the ATI Radeon HD 5770 and ATI Mobility Radeon HD 5570, with delta percentages of -0.5% and -0.2%, respectively. This places its raw compute performance in the range of graphics cards from over a decade ago. The pixel rate is 48.00 GPixel/s, and the texture rate is 96.00 GTexel/s, with an FP32 performance of 6.144 TFLOPS.

In Doom, this GPU is the definitive bottleneck. The measured FPS at 1080p Low is 96, which is playable but not exceptional. At any higher setting, the frame rate drops significantly. The fact that the GPU shares system memory is a likely contributor to the steep performance penalties when resolution and detail levels increase. The shared memory bus must compete with the CPU for bandwidth, which can cause stutters and lower average frame rates in demanding scenes. The data shows a clear ceiling: at 4K Ultra, the combo manages only 20 FPS, which is effectively unplayable. The GPU's role is to render the image, and its processing and memory bandwidth constraints are the primary cause of the low frame rates observed across all configurations. The results indicate that the Arc B370's performance is sufficient only for low-resolution, low-detail gaming in Doom.

Settings Recommendations — which preset gives the best experience per the measured rows

The measured data provides a clear hierarchy of performance across settings and resolutions. The goal here is to determine which setting preset offers the best balance between visual quality and playable frame rates. The data includes four presets: Low, Medium, High, and Ultra.

At 1080p, the Low preset yields an average of 96 FPS, which is the highest frame rate in the entire dataset. The Medium preset drops to 84 FPS, while High and Ultra fall to 71 FPS and 58 FPS, respectively. All of these are generally playable for a fast-paced FPS, but the difference between Low and Ultra is a 38 FPS gap. The Medium preset, with a min FPS of 71, offers a solid compromise. For a game like Doom, which requires high frame rates for smooth motion, the Medium preset at 1080p is the recommended choice. It provides a substantial visual upgrade over Low while maintaining an average FPS that is 13 points higher than High.

At 1440p, the situation becomes more challenging. The Low preset produces 62 FPS, which is playable. The Medium preset drops to 54 FPS, with a min of 46 FPS, which might be borderline for some players. High and Ultra are worse, at 46 FPS and 37 FPS, respectively. The Low preset is the only one that consistently stays above the 60 FPS threshold. Therefore, for 1440p, the Low preset is the recommended setting to maintain a fluid experience.

At 4K, none of the presets are capable of providing a good experience. The Low preset manages 34 FPS, Medium drops to 29 FPS, High to 25 FPS, and Ultra to a slideshow-like 20 FPS. The data suggests that 4K gaming is not viable with this combo. Even the lowest settings do not reach a playable threshold. The best course of action at 4K would be to lower the resolution to 1440p or 1080p. The Medium preset at 1080p is the sweet spot for the entire dataset, delivering an 84 FPS average while offering more visual fidelity than Low.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data is consistent and shows a predictable trend: performance scales down as resolution and detail settings increase. The following breakdown details the exact numbers for each configuration.

At 1920x1080, the combo delivers its best performance. The Low preset averages 96 FPS. The Medium preset averages 84 FPS, with a minimum of 71 FPS and a maximum of 96 FPS. The High preset averages 71 FPS. The Ultra preset averages 58 FPS. This is the only resolution where all presets are above 55 FPS.

At 2560x1440, the frame rates drop considerably. The Low preset averages 62 FPS. The Medium preset averages 54 FPS, with a minimum of 46 FPS and a maximum of 62 FPS. The High preset averages 46 FPS. The Ultra preset averages 37 FPS. The step from 1080p to 1440p costs roughly 35% performance at the Low settings (96 to 62 FPS).

At 3840x2160, the performance is poor across the board. The Low preset averages 34 FPS. The Medium preset averages 29 FPS, with a minimum of 25 FPS and a maximum of 34 FPS. The High preset averages 25 FPS. The Ultra preset averages 20 FPS. The step from 1440p to 4K costs another 45% performance at the Low settings (62 to 34 FPS).

The min and max FPS data is only available for the Medium preset at each resolution. At 1080p, the spread is from 71 to 96 FPS. At 1440p, the spread is from 46 to 62 FPS. At 4K, the spread is from 25 to 34 FPS. This limited data suggests that frame pacing is consistent, but the average frame rate is the primary concern, as even the maximum FPS at 4K Medium is lower than the minimum FPS at 1080p Medium.

Q: What is the combo's overall ranking among all tested systems for Doom?

A: The combo ranks 2696 out of 2930 tested combos for this game. This places it in the bottom 10% of all configurations tested, highlighting its performance limitations due to the integrated GPU.

How This Combo Ranks

The comboRankInGame data places this specific configuration at rank 2696 out of 2930 tested combos. This is a low ranking, placing it in the bottom 8% of all tested systems for Doom. The percentileVsAllGpus for the Arc B370 is 5, which aligns with this ranking. This is a direct consequence of the GPU's low compute performance. The CPU, on the other hand, ranks in the 79th percentile for all CPUs, indicating it is a high-performing part.

The ranking illustrates the imbalance of this pairing. The processor does not contribute to the low rank; rather, the GPU holds the entire system back. The data suggests that this combo is outperformed by the vast majority of configurations, including those with older but more powerful discrete graphics cards. The 2696th rank is a quantitative summary of the performance data seen in the measured FPS: this system is not built for high-end gaming, and its ranking reflects that. It sits just above the bottom 234 combos, which likely include systems with even weaker integrated graphics or severely outdated hardware.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling data is the most revealing aspect of this analysis. It clearly identifies the limiting component as the GPU. When moving from 1920x1080 to 2560x1440 at the Low settings preset, the average FPS drops from 96 to 62, a decrease of 34 FPS, or roughly 35%. When moving from 2560x1440 to 3840x2160, the FPS drops from 62 to 34, a further decrease of 28 FPS, or roughly 45%.

This pattern is the definitive indicator of a GPU bottleneck. The CPU's workload in a game like Doom is largely independent of resolution; the number of objects, AI routines, and physics calculations remain the same whether the game is rendered at 1080p or 4K. If the CPU were the limiting factor, the frame rate at 4K would be very similar to the frame rate at 1080p, because the CPU would still be producing the same number of frames per second, regardless of the pixel count. The GPU would simply be waiting for the CPU to finish its work.

Instead, the data shows a linear relationship between pixel count and frame rate. The GPU's fillrate and memory bandwidth are being taxed more heavily as the resolution increases. The Intel Arc B370, with its shared memory and low pixel rate, cannot keep up with the demands of rendering more pixels. The frame rate drops proportionally to the increase in resolution. The 4K resolution has roughly 4 times the pixels of 1080p, and the frame rate drops from 96 to 34 FPS, which is a factor of 2.8. This close correlation confirms that the GPU is saturated and is the primary constraint on performance. The CPU is, in this scenario, a passive observer, waiting for the GPU to complete its rendering tasks.
