Minimum

The AMD Ryzen 7 7800X3D paired with the Intel Arc B390 produces a profoundly GPU-limited experience in Minimum, a 2014 Third-Person Shooter. The integrated-class graphics solution is the overwhelming bottleneck at every tested setting and resolution, with the 8-core, 16-thread Zen 4 processor effectively idling. Benchmark results show a combo that ranks 3299th out of 3712 tested combinations, placing it in the bottom 11% of all systems, yet the frame rates suggest a playable experience at 1080p with modest settings.

Resolution Scaling

The performance drop from 1080p to 4K is stark, revealing a graphics core that struggles as pixel count increases. At High settings, the average frame rate falls from 61 FPS at 1920x1080 to 39 FPS at 2560x1440, a 36% reduction, and then plummets to 21 FPS at 3840x2160, a 66% drop from the 1080p baseline. This scaling curve is characteristic of a system where the Intel Arc B390’s 1536 shading units and 24 ROPs are saturated well before the CPU can become a factor.

The Low preset tells a similar story with slightly better absolute numbers. The transition from 1080p to 1440p sees a decline from 95 FPS to 61 FPS, a 36% loss, while moving from 1440p to 4K further reduces performance to 33 FPS, a 46% drop. The fact that even at Low settings the 4K result is just one-third of the 1080p result indicates that the GPU’s fill rate and memory bandwidth—listed as "System Shared" and "System Dependent"—are the limiting components, not the CPU’s 4.20 GHz base clock or 5.00 GHz boost clock.

Ultra settings magnify the scaling penalty. The 46 FPS at 1080p falls to 30 FPS at 1440p and then to 16 FPS at 4K. The magnitude of these losses—35% and 65% respectively—is nearly identical to the High preset, which suggests the bottleneck is purely pixel-throughput driven. The Ryzen 7 7800X3D’s 96 MB of shared L3 cache and 83.2 GB/s of DDR5 memory bandwidth are irrelevant here; the Arc B390’s 7.680 TFLOPS FP32 compute simply cannot sustain higher frame rates as resolution increases.

Settings Recommendations

For 1080p displays, the Low preset delivers the best measured experience, with an average of 95 FPS. This is the only configuration in the entire dataset that approaches high-refresh-rate territory, and it does so without the frame time variance seen elsewhere. The Medium preset at 1080p offers 72 FPS with a minimum of 62 FPS and a maximum of 83 FPS, providing a 24% performance penalty relative to Low but presumably better visual fidelity. Given that the game is a Third-Person Shooter from 2014, the Medium preset at 1080p represents the best balance of smoothness and quality, staying above 60 FPS at all measured points.

At 1440p, the situation becomes more constrained. Low settings produce 61 FPS, which is playable but with no headroom for demanding scenes. Medium settings drop to 47 FPS with a minimum of 40 FPS, which may introduce visible stutter during combat. High and Ultra settings at 1440p yield 39 FPS and 30 FPS respectively, making them unsuitable for fast-paced gameplay. Users with 1440p panels should stick to Low or Medium, accepting that the latter will dip below 45 FPS.

4K is not a viable resolution for this combo. Even Low settings only reach 33 FPS, and the Medium preset’s average of 25 FPS with a minimum of 21 FPS is below the threshold for comfortable play. High and Ultra at 4K produce 21 FPS and 16 FPS respectively, which are effectively slideshows. The data clearly shows that this pairing is intended for 1080p gaming, with 1440p possible only at the lowest quality settings.

How This Combo Ranks

The combo rank of 3299 out of 3712 places this system in the 11th percentile of all tested combinations in Minimum. This is a poor showing, but it must be contextualized by the GPU’s standalone performance. The Intel Arc B390 sits in the 9th percentile of all GPUs, with a 3DMark Steel Nomad DX12 score of 1482. Its nearest rivals are the NVIDIA GeForce GT 520MX, which scores 1463 (1.3% lower), and the NVIDIA GeForce 800M at 1460 (1.5% lower). The Arc B390 is 2.5% faster than the GeForce GT 625 OEM and 2.7% faster than the GeForce GT 710, all of which are entry-level parts from a decade ago.

The CPU, by contrast, is a high-end part. The Ryzen 7 7800X3D ranks in the 83rd percentile of all CPUs, with an average benchmark score of 33079. Its nearest rivals include the AMD Ryzen 7 8700G and Intel Core i7-13650HX, both scoring 33089 (0% delta), and the AMD Ryzen 7 7745HX at 33091 (0% delta). The only rival with a measurable difference is the AMD Ryzen 9 PRO 6950H, which is 0.4% slower. This massive disparity between a top-tier CPU and a bottom-tier GPU explains the combo’s low rank—the system is only as fast as its weakest link, and the Arc B390 is a severe weak link.

Measured FPS Breakdown

At 1920x1080, the full settings sweep shows a clear hierarchy. Low averages 95 FPS, Medium averages 72 FPS with a range of 62 to 83 FPS, High averages 61 FPS, and Ultra drops to 46 FPS. The step from Low to Medium costs 23 FPS, while the step from Medium to High costs another 11 FPS. The jump from High to Ultra is a 15 FPS loss, which represents a 25% reduction for what is typically a marginal visual gain in a 2014 title.

At 2560x1440, the same pattern holds but with compressed values. Low averages 61 FPS, Medium averages 47 FPS (minimum 40, maximum 54), High averages 39 FPS, and Ultra averages 30 FPS. The delta between Low and Ultra is 31 FPS, meaning Ultra delivers less than half the frame rate of Low. The Medium preset’s minimum of 40 FPS is particularly notable, as it suggests that even moderately complex scenes can cause the Arc B390 to dip below smooth thresholds.

At 3840x2160, the results are uniformly poor. Low averages 33 FPS, Medium averages 25 FPS (minimum 21, maximum 29), High averages 21 FPS, and Ultra averages 16 FPS. The spread from Low to Ultra is just 17 FPS, demonstrating that the GPU is so overwhelmed that settings changes have diminishing returns. The Medium preset’s minimum of 21 FPS matches the High preset’s average, indicating that frame pacing is erratic at this resolution.

CPU Role

The Ryzen 7 7800X3D is a desktop processor built on the Zen 4 architecture, codenamed Raphael, and manufactured on a 5 nm process at TSMC. It features 8 cores and 16 threads, with a base clock of 4.20 GHz and a boost clock of 5.00 GHz. The chip has a 120 W TDP and uses a dual-channel DDR5 memory interface with a bandwidth of 83.2 GB/s. Its cache hierarchy includes 64 KB of L1 per core, 1 MB of L2 per core, and a substantial 96 MB of shared L3 cache.

In Minimum, the CPU’s role is minimal due to the GPU bottleneck. The 3DMark multi-threaded scores show 7980 for 16 threads and 6539 for 8 threads, while single-thread performance is 959. Cinebench R23 results show 16817 multi-core and 1713 single-core. These numbers indicate a processor that could easily feed a much more powerful GPU, but the Arc B390’s 80 W TDP and integrated graphics design (with "System Shared" memory) prevent the CPU from ever being challenged.

The 7800X3D’s 96 MB of L3 cache is a notable asset for gaming, but it is wasted here because the GPU cannot render frames fast enough to benefit from the CPU’s low-latency cache access. The PassMark physics score of 3522 and integer math score of 103639 further confirm that the CPU has ample compute headroom. In any scenario where the GPU were upgraded, this processor would continue to perform well, but with the current Arc B390, the CPU is effectively idling while the GPU operates at its limits. The data suggests that this pairing is fundamentally unbalanced, with the CPU contributing nothing to the frame rates measured in this game.
