Doom

Measured FPS Breakdown

Starting at 1920x1080, the recorded data shows a clear progression as settings scale. At Low, the combination averages 107 FPS, which is the highest observed frame rate for this pairing across all resolutions. Medium drops the average to 93 FPS with a minimum of 79 FPS and a maximum of 107 FPS. High settings produce 78 FPS on average, while Ultra, the most demanding preset tested, still delivers 64 FPS. At this resolution, every preset clears the 60 FPS playability threshold, with Ultra holding a comfortable margin above the line.

Moving up to 2560x1440, the frame rates step down noticeably. Low settings average 69 FPS, which remains above the playable threshold. Medium averages exactly 60 FPS, with the recorded range spanning 51 FPS at the low end and 69 FPS at the high end. High settings fall to 51 FPS on average, and Ultra drops further to 41 FPS. Only Low and Medium qualify as playable at this resolution according to the database's 60 FPS threshold. The Medium preset sits precisely at the boundary, while High and Ultra fall below it.

At 3840x2160, the picture changes substantially. The highest average recorded at 4K is 37 FPS on Low settings. Medium produces 33 FPS on average, with a minimum of 28 FPS and a maximum of 37 FPS. High settings average 28 FPS, and Ultra averages 22 FPS. None of the presets at 4K reach the 60 FPS playability threshold, and even the least demanding setting falls nearly 40% short of that mark. The database records no playable settings at this resolution for this hardware combination.

The min and max data are only recorded for Medium presets across all resolutions: at 1080p the range is 79 to 107 FPS, at 1440p it is 51 to 69 FPS, and at 4K it is 28 to 37 FPS. These ranges show that frame pacing scales consistently with resolution, and the spread between minimum and maximum grows proportionally as the average drops.

CPU and GPU Roles

The data shows a system that becomes progressively more GPU-bound as resolution increases, but with an unusual twist: the Intel Arc B390 is an integrated-class part with a 9th percentile ranking among all GPUs, meaning it sits far below the median in raw graphics capability. The Ryzen 7 5800X, by contrast, ranks in the 81st percentile among all CPUs, a substantially stronger position relative to its own field. This imbalance suggests the GPU is the limiting factor at every resolution, but the degree of limitation shifts with workload.

At 1080p, the combination averages 107 FPS on Low settings, which is only 14 FPS higher than the 1440p Low average of 69 FPS. That is a 38 FPS gap between 1080p and 1440p, and a further 32 FPS gap between 1440p and 4K Low, where the average is 37 FPS. The scaling from 1080p to 1440p represents a 35.5% reduction in frame rate, while the scaling from 1440p to 4K represents a 46.4% reduction. These large proportional drops indicate that pixel throughput, not CPU processing, is the dominant constraint. A CPU-bound scenario would show far smaller frame rate differences when resolution changes.

The CPU's role becomes more apparent when looking at the difference between Low and Ultra presets at a fixed resolution. At 1080p, Low averages 107 FPS while Ultra averages 64 FPS, a 43 FPS spread. At 1440p, Low averages 69 FPS and Ultra averages 41 FPS, a 28 FPS spread. At 4K, Low averages 37 FPS and Ultra averages 22 FPS, a 15 FPS spread. The shrinking gap between presets as resolution climbs indicates that the GPU is saturated at higher pixel counts, leaving less headroom for settings to matter. The Ryzen 7 5800X, with 8 cores and 16 threads, has ample compute headroom for a 2016-era FPS like Doom, so CPU-side bottlenecks are unlikely to surface in the recorded data.

The Arc B390's memory configuration further reinforces the GPU-bound interpretation. Its memory is marked as System Shared with System Dependent bandwidth, meaning it relies on the host's DDR4 memory rather than dedicated VRAM. The Ryzen 7 5800X supports DDR4 with dual-channel memory and a memory bandwidth of 51.2 GB/s. At 4K, the shared memory subsystem has to feed significantly more pixels, which likely contributes to the steep frame rate collapse. This architecture explains why the largest resolution jump, from 1440p to 4K, produces the biggest proportional loss.

Best Settings per Resolution

At 1920x1080, the best settings that stay at or above 60 FPS are Ultra, with an average of 64 FPS. This is the most demanding preset available in the test set, and it clears the threshold by 4 FPS. The database lists High, Low, Medium, and Ultra all as playable at this resolution, so the recommendation is straightforward: run Ultra at 1080p. The 64 FPS average leaves a small but real buffer above the 60 FPS line, and the recorded minimum for Medium at this resolution is 79 FPS, suggesting that even the minimum frame times on Ultra would likely remain above the threshold, though min data for Ultra is not recorded.

At 2560x1440, the best settings that stay at or above 60 FPS are Medium, with an average of exactly 60 FPS. Low also qualifies as playable with 69 FPS, but Medium is the better choice because it offers higher visual quality while still meeting the threshold. The recorded minimum for Medium at 1440p is 51 FPS, which means there will be frame dips below 60 FPS during demanding scenes, but the average holds at the line. High and Ultra both fall below the playable threshold at this resolution, so they are not recommended.

At 3840x2160, no settings achieve 60 FPS. The database records an empty playable settings list and a null best settings value for 4K. The closest option is Low at 37 FPS, which is far below the threshold. Users targeting 4K with this hardware combination would need to accept a substantially reduced experience, or reduce resolution. There is no preset that delivers a playable frame rate at 4K according to the recorded data.

How This Combo Ranks

The database ranks this combination at 3300 out of 3712 tested combos for Doom, placing it in the 11.1th percentile overall. This is a low ranking, driven almost entirely by the GPU's weak standing. The Arc B390 sits at the 9th percentile among all GPUs in the database, while the Ryzen 7 5800X sits at the 81st percentile among all CPUs. The combination's rank in this specific game is consistent with the GPU's low percentile: the CPU is a strong performer, but the GPU drags the overall result down.

In context, a rank of 3300 out of 3712 means roughly 89% of tested combinations deliver better performance in Doom. This places the combo in the bottom tier of the database for this title. The frame rate data corroborates this: even at 1080p Low, the 107 FPS average is respectable, but at higher resolutions the weak GPU becomes apparent. The 4K results, with a best-case average of 37 FPS, are among the lowest recorded for any modern CPU pairing.

Similar Performance Alternatives

On the CPU side, the Ryzen 7 5800X has an average benchmark score of 29123, with nearest rivals that cluster within 1% of its score. The Intel Core Ultra 5 135H scores 29093, a 0.1% difference. The AMD Ryzen 5 5600XT scores 28940, a 0.6% difference on the lower side. The Intel Core Ultra 5 135H and AMD Ryzen 5 5600XT are essentially equivalent to the 5800X in aggregate benchmark performance, while the Intel Xeon Phi 7210 and Intel Core i5-13500HX are within half a percent. Any of these CPUs would behave nearly identically to the Ryzen 7 5800X in this system when paired with the same GPU.

On the GPU side, the Arc B390 has an average benchmark score of 1482, with nearest rivals that are all NVIDIA parts from the GT series era. The NVIDIA GeForce GT 520MX scores 1463, a 1.3% difference. The NVIDIA GeForce 800M scores 1460, a 1.5% difference. The NVIDIA GeForce GT 625 OEM scores 1446, a 2.5% difference. The NVIDIA GeForce GT 710 scores 1443, a 2.7% difference. All four rivals fall within 2.7% of the Arc B390's score, meaning a user swapping between any of these GPUs would see nearly identical frame rates in Doom at every resolution and setting tested. None of these GPUs would change the fundamental conclusion about playability thresholds at 1440p or 4K.

The balanced view from the database is clear: the Ryzen 7 5800X is a strong CPU with multiple near-identical alternatives, but the Arc B390 sits in a very narrow performance band with several legacy NVIDIA parts. The CPU's rivals are all within 0.6% of each other, and the GPU's rivals are all within 2.7% of each other. This means the measured FPS data is representative of a broader set of hardware than just this exact pairing.

FAQ
