Doom

The AMD Ryzen 5 5600GT paired with the Intel Arc B390 in Doom presents a dataset defined by stark contrasts. The CPU is a modern 6-core, 12-thread Zen 3 part with a strong showing in synthetic benchmarks, while the GPU is an integrated graphics solution based on the Xe3-LPG architecture that ranks in the 9th percentile of all tested GPUs. The measured frame rates reveal a system where the graphics processor is the definitive performance bottleneck at every resolution and setting tier, making this combination suitable only for the most modest performance targets in this title.

FAQ

Q: What is the best average FPS this combo achieves at 1920x1080?

A: The highest measured average frame rate is 107 FPS, which is achieved with the Low preset. This is significantly higher than the 64 FPS average recorded at the Ultra preset, indicating that the GPU is heavily taxed by higher graphical fidelity.

Q: How does the combo perform at 3840x2160 (4K) resolution?

A: Performance at 4K is poor across all settings. The average FPS ranges from 22 FPS at Ultra to 37 FPS at Low. Even the best-case scenario at 4K falls below the threshold for smooth, consistent gameplay, with the Medium preset showing a minimum FPS of 28.

Q: Which component is the limiting factor in this configuration?

A: The data strongly indicates the Intel Arc B390 is the limiting factor. The Ryzen 5 5600GT has a high average benchmark score and ranks in the 74th percentile of all CPUs, while the Arc B390 scores just 1482 in its benchmark and ranks in the 9th percentile of GPUs. The GPU's low performance relative to the CPU creates an imbalance.

Q: What is the frame rate difference between the Low and Ultra presets at 2560x1440?

A: At 1440p, the Low preset averages 69 FPS, while the Ultra preset averages 41 FPS. This represents a drop of 28 FPS when moving from the lowest to the highest quality settings, demonstrating the GPU's struggle with the increased shading and texture work required by the Ultra preset.

Q: What is the combo's ranking among all tested combinations for this game?

A: The combination ranks 2580th out of 2930 tested combos for Doom. This places it in the bottom 12% of all tested systems, consistent with the very low percentile ranking of the Intel Arc B390 graphics processor.

Q: Does the Ryzen 5 5600GT's integrated graphics play a role in this benchmark?

A: No. The benchmark configuration uses the discrete Intel Arc B390 GPU. The Ryzen 5 5600GT does list an integrated graphics unit, the Radeon Vega 7, but the measured FPS data is for the system operating with the Arc B390.

GPU Role

The Intel Arc B390 is the decisive component in this configuration, and its specifications clearly indicate why it is the bottleneck. The GPU has a base clock of 300 MHz and a boost clock of 2500 MHz, which is a wide dynamic range. However, its memory allocation is listed as "System Shared," meaning it relies on the system's main DDR4 memory rather than dedicated VRAM. The memory bus width and bandwidth are also "System Shared" and "System Dependent," respectively. This architecture means the GPU's performance is tied to the system's memory performance, which is a significant disadvantage for a graphics workload.

The GPU's compute resources are similarly constrained. It has 1536 shading units, 48 texture mapping units, and 24 raster output units. This hardware configuration can produce a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. Its FP32 throughput is 7.680 TFLOPS. While these are not negligible figures on paper, the data shows they are insufficient for demanding scenarios in Doom. The GPU's benchmark score in 3DMark Steel Nomad is 1482, which places it in the 9th percentile of all GPUs. Its nearest rivals, according to the data, are the NVIDIA GeForce GT 520MX, GT 625 OEM, and GT 710, which are all entry-level parts from years ago. This context makes the measured FPS results predictable: the GPU simply does not have enough raw throughput or memory bandwidth to feed the display at high resolutions and quality settings.

Resolution Scaling

The measured FPS data shows a severe and consistent performance penalty as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average FPS drops from 78 at 1080p, to 51 at 1440p, and finally to 28 at 4K. This is a steep curve. The drop from 1080p to 1440p represents a 35% reduction in average FPS, and the drop from 1440p to 4K represents a further 45% reduction. This scaling pattern is a classic indicator of a GPU-bound system. As the resolution increases, the number of pixels the rasterizer must fill grows exponentially, placing a much heavier load on the GPU's pixel fillrate and memory bandwidth.

This behavior is consistent across all settings. At the Low preset, the average FPS falls from 107 at 1080p to 69 at 1440p and then to 37 at 4K. Even at the lowest quality settings, the GPU cannot maintain a playable frame rate at 4K. The data clearly shows that the Arc B390's performance limit is reached long before the CPU's processing capabilities are stressed. The Ryzen 5 5600GT is a capable processor, but its potential is untapped because the GPU is unable to render frames fast enough to keep up. The performance degradation from resolution scaling is the most direct evidence that this system is severely GPU-limited in Doom.

Settings Recommendations

Based on the measured rows, the optimal experience for this combination is found at 1920x1080 with the Low preset. This configuration yields an average FPS of 107, which is the only setting that approaches high-refresh-rate territory. The Medium preset at 1080p averages 93 FPS, which is also playable and offers a better visual experience, but the Low preset provides the largest performance headroom. At 1080p, the Ultra preset averages 64 FPS, which is acceptable but represents a significant drop from the lower presets.

At 2560x1440, the situation becomes more constrained. The Low preset averages 69 FPS, which is the only setting at this resolution that provides a consistently smooth experience. The Medium preset averages 60 FPS, but the minimum FPS of 51 indicates that it can dip lower during intense scenes. The High and Ultra presets at 1440p, averaging 51 and 41 FPS respectively, are not recommended for a responsive experience.

At 3840x2160, no setting is recommended. Even the Low preset averages only 37 FPS, which is generally considered too low for a fast-paced FPS game. The Ultra preset at 4K averages just 22 FPS, making it effectively unplayable. Therefore, the data supports using the Low preset at 1080p for the best balance of performance and playability, with the Medium preset at 1080p as a viable alternative for those who prioritize visual quality over maximum frame rate.

Measured FPS Breakdown

The full dataset provides a clear picture of the system's capabilities across all tested configurations.

At 1920x1080, the highest average FPS recorded is 107 at the Low preset. The Medium preset averages 93 FPS, with a minimum of 79 and a maximum of 107. The High preset averages 78 FPS, and the Ultra preset averages 64 FPS. This resolution offers the only playable performance levels in the entire dataset.

Moving to 2560x1440, the Low preset produces an average of 69 FPS. The Medium preset averages 60 FPS, with a minimum of 51 and a maximum of 69. The High preset drops to an average of 51 FPS, and the Ultra preset falls further to 41 FPS. The performance at this resolution is marginal for the lower settings and inadequate for the higher ones.

At 3840x2160, the results are consistently poor. The Low preset averages 37 FPS. The Medium preset averages 33 FPS, with a minimum of 28 and a maximum of 37. The High preset averages 28 FPS, and the Ultra preset averages just 22 FPS. The data shows that the GPU is completely overwhelmed at this resolution, regardless of the quality settings chosen.

CPU Role

The AMD Ryzen 5 5600GT is a 6-core, 12-thread processor based on the Zen 3 architecture, built on a 7 nm process. It has a base clock of 3.60 GHz and a boost clock of 4.60 GHz. This CPU is a strong performer in its own right. Its Cinebench R23 multicore score is 17272, and its single-core score is 2438. In Geekbench, it scores 7986 multicore and 1843 single-core. These results place the CPU in the 74th percentile of all CPUs, with an average benchmark score of 20733.

The CPU's nearest rivals in terms of average score include the Intel Core i5-12490F, which is just 0.3% slower, and the Intel Core Ultra 5 125U, which is 0.4% slower. This indicates that the 5600GT is a very competitive mid-range processor. However, in this specific configuration, the CPU's power is irrelevant to the final outcome. The frame rates in Doom are dictated entirely by the GPU. The CPU's 16 MB of L3 cache and high boost clock are more than sufficient to handle the game's logic and draw calls, but the GPU cannot render the frames fast enough for the CPU to become a limiting factor. The benchmark data shows a system where the CPU is waiting for the GPU at every turn.

How This Combo Ranks

The combination of the AMD Ryzen 5 5600GT and the Intel Arc B390 ranks 2580th out of 2930 tested combos for Doom. This places the system in the bottom 12% of all tested configurations. This low ranking is a direct consequence of the GPU's performance. The Ryzen 5 5600GT's individual ranking is high, in the 74th percentile of all CPUs. In contrast, the Intel Arc B390 ranks in the 9th percentile of all GPUs. The pairing of a high-performing CPU with a very low-performing GPU creates a massive imbalance that drags the overall combo ranking down.

The GPU's nearest rivals are all ancient, low-end NVIDIA parts. The Arc B390's benchmark score is only 1.3% higher than the GeForce GT 520MX and 2.5% higher than the GT 625 OEM. These are not comparable modern GPUs, and their inclusion in the nearest rivals list highlights how far behind the Arc B390 is in raw performance. The data makes it clear that while the CPU is a solid foundation, the GPU is a severe limiting factor. The 2580th ranking reflects the reality of the system's performance: it is a combination built around a capable CPU but crippled by a GPU that cannot deliver adequate frame rates in a demanding FPS title, except at the lowest resolution and quality settings.
