Undisputed

The AMD Ryzen 7 7800X3D paired with the Intel Arc B390 presents a striking imbalance in Undisputed, a sports title that scales heavily with resolution. The data shows a system where the CPU is capable of delivering very high frame rates, but the GPU becomes the overwhelming bottleneck as graphical load increases. This analysis walks through the measured FPS data to explain the performance profile of this specific combination.

Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and reveals a clear GPU-bound scenario. At 1080p with Low settings, the combo achieves an average of 127 FPS. Moving to 1440p Low drops that to 92 FPS, a reduction of 35 FPS. At 4K Low, the average falls to 58 FPS, which is less than half the 1080p Low result. This steep decline is a classic indicator that the Intel Arc B390, with its 9th percentile ranking among all GPUs, is the limiting component.

The trend continues across all settings presets. For High settings, the average FPS goes from 76 at 1080p, to 55 at 1440p, and finally to 35 at 4K. The Ultra preset shows the most severe scaling, starting at 49 FPS at 1080p, dropping to 35 FPS at 1440p, and bottoming out at 22 FPS at 4K. The pattern is linear and consistent: every increase in resolution imposes a heavy penalty on performance, which indicates that the GPU's rendering capabilities are being saturated well before the CPU’s processing power is exhausted.

The percentage differences between resolutions are telling. From 1080p to 1440p on Low, performance drops by roughly 27.5%. From 1440p to 4K on Low, the drop is approximately 37%. This accelerating decline suggests that the Arc B390 is not just struggling with pixel count, but also with the increased memory bandwidth demands of higher resolutions, as its memory bandwidth is listed as "System Dependent." The fact that the 4K Medium preset (42 FPS) is slower than the 1080p High preset (76 FPS) underscores that the GPU’s fill rate and shading power are the primary constraints, not the CPU.

Benchmark results indicate that the transition from 1080p to 4K on Medium settings cuts the average frame rate from 91 to 42 FPS, a loss of over half the performance. This is a far more significant drop than what would be expected from a balanced system. In a balanced configuration, the CPU would start to limit performance at lower resolutions, causing the FPS drop to plateau or flatten out as resolution increases. Here, the FPS continues to plummet, proving that the Intel Arc B390 is the sole bottleneck. Users with this combo should expect that 4K gaming is only viable on the Low preset, and even then, the 58 FPS average is not consistently smooth.

CPU Role

The AMD Ryzen 7 7800X3D is a high-end desktop processor with 8 cores and 16 threads, based on the Zen 4 architecture. It has a base clock of 4.20 GHz and a boost clock of 5.00 GHz. Its benchmark scores are robust, with a Cinebench R23 multicore score of 16817 and a single-core score of 1713. In the context of Undisputed, the CPU’s role is to feed the GPU with draw calls and game logic, and the data suggests it performs this task with ease.

The processor’s 96 MB of shared L3 cache is a notable feature, but the measured FPS data shows that this cache is not a limiting factor in this specific game. The most compelling evidence for the CPU’s sufficiency is that the 1080p Low preset produces 127 FPS. This high frame rate is far beyond what the GPU can handle at higher settings, meaning the CPU is capable of pushing far more frames than the Arc B390 can render. The CPU is simply not the constraint.

Comparing the Ryzen 7 7800X3D to its nearest rivals shows it is in a performance tier where it excels. Its average benchmark score of 33079 is statistically identical to the AMD Ryzen 7 8700G (33089), the Intel Core i7-13650HX (33089), and the AMD Ryzen 7 7745HX (33091), with a delta of 0%. It is 0.4% ahead of the AMD Ryzen 9 PRO 6950H (33201). This parity means that swapping the 7800X3D for any of these rivals would likely yield the exact same frame rates in Undisputed, because the game is not CPU-limited at any tested setting.

The data shows that the CPU’s single-thread performance, as measured by a Geekbench single-core score of 2426, is more than adequate. Even in the most CPU-intensive scenarios, such as 1080p Low where the frame rate is highest, the CPU is not the bottleneck. The 7800X3D is performing its job so well that it is effectively invisible in the performance equation; the only factor that matters is the GPU. For this game, the CPU is a non-factor, and its high cost would not translate to any additional FPS in Undisputed compared to a much cheaper processor.

FAQ

*Q: Can this combo run Undisputed at 4K smoothly?*

A: No. At 4K Ultra, the average FPS is 22. At 4K High, it is 35 FPS. The only playable option is 4K Low, which yields an average of 58 FPS, but this is still below the 60 FPS threshold often considered ideal.

Q: What is the best resolution for this system?

A: 1080p is the most viable. The Low preset achieves 127 FPS, and the Medium preset achieves 91 FPS. Even the High preset at 76 FPS is smoother than any 1440p or 4K result.

Q: Is the CPU or GPU the limiting factor in this game?

A: The GPU is the clear limiting factor. The Intel Arc B390 has a 9th percentile ranking among all GPUs. The FPS drops significantly as resolution increases from 1080p to 4K, indicating a GPU bottleneck. The CPU is not the constraint.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: The Arc B390 has a 3DMark Steel Nomad score of 1482. It is 1.3% faster than the NVIDIA GeForce GT 520MX (1463), and 2.7% faster than the NVIDIA GeForce GT 710 (1443). These are all very low-end GPUs.

Q: Is there any scenario where the CPU's 3D V-Cache helps in this game?

A: The benchmark data does not indicate any specific benefit. The FPS is consistently limited by the GPU at all settings. The CPU’s performance is sufficient, but its advanced cache does not translate to higher frame rates because the GPU cannot keep up.

How This Combo Ranks

The combination of the AMD Ryzen 7 7800X3D and Intel Arc B390 ranks 2491 out of 2813 tested combos in Undisputed. This places it in the bottom 11.5% of all systems tested, which is a poor result. The ranking is heavily dragged down by the GPU, which has a 9th percentile ranking among all GPUs. This low ranking is consistent with the measured FPS data, which shows the system struggling to maintain playable frame rates at higher resolutions and settings.

The combo’s rank is particularly poor considering the CPU’s high standing. The Ryzen 7 7800X3D has an 83rd percentile ranking among all CPUs, indicating it is a top-tier processor. However, the pairing with a bottom-tier GPU creates a severe bottleneck. The data suggests that the CPU’s potential is almost entirely wasted in this configuration. The rank of 2491 means that 322 other combos perform worse, but the vast majority of systems (over 88%) will outperform this specific pairing.

This ranking makes sense when looking at the GPU’s nearest rivals. The Arc B390 is only slightly faster than the NVIDIA GeForce GT 520MX and GT 710, which are legacy, entry-level parts. The system is effectively a high-end CPU paired with a very low-end graphics solution. Users would likely see a massive improvement in rank by simply swapping the GPU for a more capable part, as the CPU is already proven to be more than sufficient for this game. The measured FPS data confirms that the GPU is the sole reason for this poor ranking.

Measured FPS Breakdown

The measured data provides a complete picture of performance across three resolutions and four settings presets. Here is the exact breakdown.

At 1920x1080, the results are as follows:

• Low: Average 127 FPS.
• Medium: Average 91 FPS, with a minimum of 78 FPS and a maximum of 105 FPS.
• High: Average 76 FPS.
• Ultra: Average 49 FPS.

At 2560x1440, the results show a significant drop:

• Low: Average 92 FPS.
• Medium: Average 66 FPS, with a minimum of 56 FPS and a maximum of 76 FPS.
• High: Average 55 FPS.
• Ultra: Average 35 FPS.

At 3840x2160, the performance is largely unplayable except for the Low preset:

• Low: Average 58 FPS.
• Medium: Average 42 FPS, with a minimum of 36 FPS and a maximum of 48 FPS.
• High: Average 35 FPS.
• Ultra: Average 22 FPS.

The data shows that the Medium preset is the only one with min/max FPS values provided, indicating that the other presets may have more variable frame pacing or were measured differently. The 1080p Medium preset has a 27 FPS spread between minimum and maximum, while the 1440p Medium has a 20 FPS spread. The 4K Medium preset has a 12 FPS spread, which is tighter but still shows instability. The overall trend is that higher settings and resolutions lead to lower average FPS, with the 1080p Low preset being the only configuration that consistently exceeds 120 FPS.

Settings Recommendations

Based on the measured FPS, the best experience for this combo is at 1080p. The Low preset provides the highest average frame rate at 127 FPS, which is ideal for competitive play or high refresh rate monitors. However, if visual fidelity is a priority, the Medium preset at 91 FPS is an excellent compromise, offering a significant visual upgrade over Low while still maintaining a frame rate well above 60 FPS. The High preset at 76 FPS is also playable and provides a better visual experience than Medium, though the frame rate is lower.

At 1440p, the options are more limited. The Low preset at 92 FPS is the only setting that provides a smooth experience. The Medium preset at 66 FPS is borderline, and the High preset at 55 FPS is below the 60 FPS target. The Ultra preset at 35 FPS is not recommended. For 4K gaming, the only viable option is the Low preset at 58 FPS. All other 4K settings result in average frame rates below 42 FPS, which is not a smooth experience for a sports game.

The data suggests that the best overall experience is 1080p with Medium settings, as it provides a high frame rate with improved visuals over Low. The 91 FPS average is smooth, and the minimum of 78 FPS ensures that the frame rate rarely drops into noticeable stutter territory. For users who prioritize frame rate above all else, 1080p Low is the clear winner. For those who want a balance, 1080p Medium is the sweet spot. Pushing to 1440p or 4K is not recommended unless the user is willing to accept Low settings and sub-60 FPS performance.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on a 3 nm process. It has a base clock of 300 MHz and a boost clock of 2500 MHz. Its performance is extremely limited, as shown by its 9th percentile ranking among all GPUs. The measured 3DMark Steel Nomad score of 1482 places it in the same performance tier as the NVIDIA GeForce GT 520MX and GT 710, which are ancient, low-end discrete GPUs. This GPU is fundamentally not designed for modern gaming at high resolutions.

The GPU’s memory configuration is "System Shared," meaning it relies on the system’s main memory for VRAM. This is a major disadvantage, as the memory bandwidth is "System Dependent" and not dedicated to the GPU. This explains why performance drops so sharply at higher resolutions, as the GPU must compete with the CPU for memory bandwidth. The 7.680 TFLOPS of FP32 performance is insufficient for the demands of Undisputed at 1440p or 4K with high settings.

The data shows that the GPU is the absolute bottleneck. At 1080p Low, the system achieves 127 FPS, which is likely near the GPU’s maximum output. At higher settings, the GPU’s shading units and texture mapping units are overwhelmed, leading to the severe FPS drops seen in the data. The GPU’s 1536 shading units and 48 TMUs are simply not enough to handle the game’s visual effects at higher presets. The RT cores (12) and DirectX 12 Ultimate support are irrelevant when the raw rasterization performance is this low.

The GPU’s 80 W TDP and IGP slot width confirm it is an integrated solution, not a high-performance discrete card. The benchmark results indicate that this GPU is only suitable for 1080p gaming at Low to Medium settings in Undisputed. Any attempt to push higher resolutions or settings will result in a poor experience. The Arc B390 is the primary reason this combo ranks 2491 out of 2813, and its limitations are evident in every measured metric.
