Doom

The AMD Ryzen 7 5800X paired with the Intel Arc B390 ranks near the bottom of the database for Doom, placing 2580th out of 2930 tested combinations. This positions the combo in the 12th percentile of all tested systems, indicating that while the CPU is a high-end desktop part, the integrated GPU severely bottlenecks the experience. The data shows a system that can run the game, but only at modest settings and resolutions, with the graphics card being the definitive limiting factor in every measurable scenario.

How This Combo Ranks

The combination of the Ryzen 7 5800X and the Arc B390 achieves a rank of 2580 out of 2930 tested combos in Doom. This places it in the bottom 12% of all systems tested, a position driven almost entirely by the GPU's performance tier. The Arc B390 itself sits at the 9th percentile among all GPUs, with an average benchmark score of 1482, which aligns with its low-end positioning. In contrast, the Ryzen 7 5800X is a far more capable component, holding the 81st percentile among all CPUs.

This disparity between CPU and GPU capability creates a profoundly unbalanced system for gaming. The benchmark results show that even at 1080p with Low settings, the system only achieves 107 FPS, which is respectable, but the GPU's limitations become apparent as resolution and settings increase. The 5800X, with its 8 cores and 16 threads based on the Zen 3 architecture, is theoretically capable of feeding a much faster graphics card. However, the Arc B390's performance ceiling caps the entire system's output.

The nearest rivals to this GPU in the database include the NVIDIA GeForce GT 520MX, which scores 1463 (1.3% slower), and the NVIDIA GeForce 800M, scoring 1460 (1.5% slower). These are all entry-level or legacy mobile-class parts, further confirming that the B390 is not designed for high-performance gaming. The combo's rank reflects this reality: it is a system that can play Doom, but it will not provide a smooth or visually rich experience at higher demands. The CPU's strength is essentially wasted in this configuration, as it cannot push the GPU beyond its limits.

GPU Role

The Intel Arc B390 is the primary bottleneck in this system. It is an integrated graphics processor (IGP) based on the Xe3-LPG architecture, manufactured on a 3 nm process. The GPU has a base clock of 300 MHz and a boost clock of 2500 MHz, but its memory configuration is "System Shared," meaning it relies on the main system RAM rather than dedicated VRAM. This shared memory setup has a bandwidth that is "System Dependent," which is a significant drawback for a game like Doom that benefits from fast memory access.

The GPU's raw compute specifications are modest. It features 1536 shading units, 48 texture mapping units, and 24 raster output units. Its pixel rate is 60.00 GPixel/s and its texture rate is 120.0 GTexel/s. The FP32 performance is rated at 7.680 TFLOPS. These figures place it in the same performance bracket as the NVIDIA GeForce GT 710 and GT 625 OEM, based on the nearestRivals deltaPct values of 2.7% and 2.5% respectively. This is not a GPU built for 1440p or 4K gaming at high frame rates.

In Doom, the GPU's limitations are stark. At 4K with Ultra settings, the average FPS drops to 22, which is unplayable. Even at 1080p with Low settings, the GPU manages 107 FPS, but this is its peak performance. The data suggests that the Arc B390 is capable of running Doom only at lower resolutions and with reduced graphical fidelity. The boost clock of 2500 MHz helps, but the lack of dedicated VRAM and the low overall throughput prevent it from handling the game's engine demands at higher settings. The GPU is simply outclassed for this application.

Resolution Scaling

The measured FPS data shows a clear and predictable trend: performance degrades significantly as resolution increases. At 1080p with Low settings, the system achieves 107 FPS. Moving to 1440p Low drops this to 69 FPS, a 35.5% reduction. At 4K Low, the average FPS falls to 37, which is a 65.4% reduction from the 1080p baseline. This scaling pattern indicates that the GPU is the limiting component; if the CPU were the bottleneck, the frame rates would be more consistent across resolutions.

Looking at High settings, the trend continues. The system delivers 78 FPS at 1080p, 51 FPS at 1440p, and 28 FPS at 4K. The drop from 1080p to 1440p is 34.6%, and from 1440p to 4K is 45.1%. This steep decline is typical of a GPU that is overwhelmed by the increasing pixel count. The Arc B390's 24 ROPs and 60.00 GPixel/s pixel rate are insufficient for high-resolution rendering, causing the frame rate to crater.

The Medium settings data provides the only min and max FPS readings in the pack. At 4K Medium, the average is 33 FPS, with a min of 28 and a max of 37. At 1440p Medium, the average is 60 FPS, with a min of 51 and a max of 69. At 1080p Medium, the average is 93 FPS, with a min of 79 and a max of 107. These ranges show that the frame pacing is relatively stable, but the overall performance is still low. The data confirms that this combo is best suited for 1080p gaming, as higher resolutions push the GPU past its effective limit.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is at 1080p with Medium settings. This configuration yields an average FPS of 93, with a minimum of 79 FPS and a maximum of 107 FPS. This is the only settings level where the system maintains an average above 90 FPS while still offering a reasonable visual quality. Low settings at 1080p do produce a higher average of 107 FPS, but the visual downgrade may not be worth the extra 14 FPS.

At 1440p, Medium settings provide an average of 60 FPS, which is playable but not optimal. The minimum of 51 FPS suggests occasional dips that could be noticeable during intense action. High settings at 1440p drop to 51 FPS average, which is borderline. For a smoother experience, Low settings at 1440p are preferable, offering 69 FPS average. However, the visual quality loss is significant.

4K is not a viable option for this combo. Even at Low settings, the average FPS is only 37, which is below the threshold for smooth gameplay. Ultra settings at any resolution are also problematic; the system only manages 64 FPS at 1080p Ultra and 41 FPS at 1440p Ultra. The data clearly shows that the 1080p Medium preset is the sweet spot, balancing frame rate and visual fidelity. Users seeking higher FPS should drop to Low, but those wanting better visuals should stop at Medium, as High and Ultra presets result in diminishing returns.

CPU Role

The AMD Ryzen 7 5800X plays a supporting role in this combo, providing ample processing power that the Intel Arc B390 cannot fully utilize. The CPU features 8 cores and 16 threads based on the Zen 3 architecture, with a base clock of 3.80 GHz and a boost clock of 4.70 GHz. It has a 32 MB L3 cache and supports DDR4 memory with a bandwidth of 51.2 GB/s. These specifications place it in the 81st percentile among all CPUs, with an average benchmark score of 29123.

In terms of raw performance, the 5800X achieves a Cinebench R23 multicore score of 15476 and a single-core score of 1574.5. Its Geekbench scores are 11036 for multicore and 2032 for single-core. These results show that the CPU is exceptionally strong for gaming and productivity tasks alike. However, in Doom, the CPU's power is largely irrelevant because the GPU is the limiting factor.

The nearest rival to the 5800X is the Intel Core Ultra 5 135H, which has an average score of 29093, a 0.1% difference. The AMD Ryzen 5 5600XT is also close, scoring 28940, which is 0.6% lower. This shows the 5800X is competitive with modern mid-range CPUs. The data from the measured FPS suggests that the CPU is never the bottleneck in this system; even at 1080p Low, where the GPU is at its least stressed, the CPU could likely push higher frame rates if paired with a faster GPU.

The 5800X's 16 threads are more than sufficient for Doom, which is a game that scales well with multi-core CPUs. The CPU's high single-thread performance, as evidenced by the 943 score in 3dmark_single_thread, ensures that game logic and physics calculations are handled quickly. However, the Arc B390's 7.680 TFLOPS of FP32 performance is simply too low to translate the CPU's capability into high FPS. The conclusion is that the CPU is overqualified for this GPU, and the system's performance is entirely dictated by the graphics card.
