How This Combo Ranks

The combo rank of 2491 out of 2813 places this system firmly in the lower quartile of all tested configurations for Undisputed. This ranking is predictable given the components involved: the Ryzen 9 7900X is a high-end desktop processor with a 91st percentile ranking among all CPUs, while the Arc B390 is an integrated graphics solution that lands in the 9th percentile among all GPUs. The disparity between these two components creates a bottleneck scenario where the GPU's capabilities dictate the final performance outcome.

The data shows that the CPU is not the limiting factor in this pairing. The Ryzen 9 7900X's average benchmark score of 53288 places it within 0.6% of four rival processors, all of which are server or high-end desktop chips. This score represents the 91st percentile of all CPUs, meaning the processor outperforms the vast majority of alternatives. In contrast, the GPU's average benchmark score of 1482 places it just 2.7% above the NVIDIA GeForce GT 710, a card from a much older generation, and 1.3% above the GT 520MX. The GPU's 9th percentile ranking means it outperforms only about 9% of all graphics cards in the database.

When interpreting the combo rank, it is essential to understand that the ranking reflects the combined system performance, not just the individual components. The fact that this combo still achieves 127 FPS at 1080p Low suggests that Undisputed is not particularly demanding on the GPU at lower settings, allowing the CPU's strength to show through. However, the 2491st rank also indicates that most other systems in the database achieve better overall performance, likely due to having discrete GPUs that outperform the Arc B390.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a clear GPU-bound pattern. At Low settings, the average FPS drops from 127 at 1920x1080 to 92 at 2560x1440, then to 58 at 3840x2160. This represents a 27.6% drop from 1080p to 1440p, and a 54.3% drop from 1080p to 4K. The scaling is consistent with a GPU that is heavily taxed by increased pixel counts, as the Arc B390's 24 ROPs and system-shared memory struggle to keep up with the growing render workload.

At Medium settings, the FPS progression shows a similar pattern: 91 FPS at 1080p, 66 FPS at 1440p, and 42 FPS at 4K. The percentage drops are 27.5% and 53.8% respectively, nearly identical to the Low setting scaling. This consistency suggests that the GPU is the primary bottleneck across all quality levels, with the CPU having ample headroom to handle the increased frame time demands.

The High settings curve tells a slightly different story. From 76 FPS at 1080p, the frame rate drops to 55 FPS at 1440p (a 27.6% decrease) and then to 35 FPS at 4K (a 53.9% decrease from 1080p). The Ultra settings show the most severe scaling: 49 FPS at 1080p, 35 FPS at 1440p, and 22 FPS at 4K, with percentage drops of 28.6% and 55.1% respectively. The increasing percentage drop at Ultra settings indicates that the GPU's memory bandwidth and compute resources are being saturated more aggressively, with the system-shared memory becoming a critical constraint.

The resolution scaling data strongly implies that the limiting component is the GPU. The CPU's 12 cores and 24 threads, with a boost clock of 5.60 GHz, are more than sufficient to drive frame rates well above what the GPU can deliver. The fact that the FPS drops proportionally across all settings when resolution increases is a classic sign of a GPU bottleneck, as the CPU would typically show less scaling with resolution if it were the limiting factor.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best results. Low settings produce an average of 127 FPS, which is the only configuration to exceed 100 FPS. Medium settings achieve 91 FPS average, with a minimum of 78 FPS and maximum of 105 FPS. High settings drop to 76 FPS average, and Ultra settings fall to 49 FPS average. The gap between Medium and Low is 36 FPS, while the gap between High and Ultra is 27 FPS, suggesting diminishing returns as settings increase.

At 2560x1440, the performance drops noticeably across the board. Low settings average 92 FPS, Medium settings average 66 FPS with a range of 56 to 76 FPS, High settings average 55 FPS, and Ultra settings average 35 FPS. The Medium setting's minimum of 56 FPS is still playable, but the Ultra setting's 35 FPS average is borderline for smooth gameplay. The 1440p results show a 27.6% to 28.6% reduction compared to 1080p across all settings, indicating a consistent scaling penalty.

At 3840x2160, the combo struggles to maintain playable frame rates. Low settings average 58 FPS, which is acceptable for casual play. Medium settings average 42 FPS with a minimum of 36 FPS and maximum of 48 FPS, making it marginally playable. High settings drop to 35 FPS average, and Ultra settings fall to 22 FPS average. The 4K results reveal that this combo is not suitable for high-quality gaming at this resolution, with only the Low preset approaching a smooth experience.

The measured data shows a consistent pattern of approximately 27-28% FPS reduction from 1080p to 1440p, and an additional 36-38% reduction from 1440p to 4K. This compounding effect means that 4K performance is roughly half of 1080p performance, regardless of the quality preset selected.

GPU Role

The Intel Arc B390 is the clear performance limiter in this configuration. Its specifications reveal why: the GPU has 1536 shading units, 48 TMUs, and 24 ROPs, with 12 ray tracing cores. The base clock is 300 MHz with a boost clock of 2500 MHz, and its pixel rate is 60.00 GPixel/s with a texture rate of 120.0 GTexel/s. The FP32 compute throughput is 7.680 TFLOPS, with FP16 at 15.36 TFLOPS (2:1).

The most critical limitation is the memory configuration. The Arc B390 uses System Shared memory, meaning it has no dedicated VRAM. The memory size, type, and bus width are all listed as "System Shared," and bandwidth is "System Dependent." This means the GPU must compete with the CPU for memory bandwidth through the system's DDR5 memory, which is limited to 83.2 GB/s by the CPU's dual-channel memory bus. This shared memory architecture explains why the GPU's performance degrades so significantly at higher resolutions and settings, as the increased memory demand creates contention with the CPU.

The GPU's 9th percentile ranking places it near the very bottom of the database. Its average benchmark score of 1482 is just 1.3% above the NVIDIA GeForce GT 520MX and 2.5% above the GeForce GT 625 OEM. These rivals are all older, low-end GPUs, indicating the Arc B390's performance class. In Undisputed, this translates to playable frame rates only at lower settings and resolutions, with the GPU's 80 W TDP suggesting it is designed for power efficiency rather than raw performance.

The measured FPS data shows that the GPU's shared memory is likely the primary constraint. At 1080p Low, the combo achieves 127 FPS, which requires significant memory bandwidth to feed the render pipeline. As resolution increases, the memory bandwidth requirement grows exponentially, and the system-shared memory becomes a bottleneck. The fact that the GPU's boost clock reaches 2500 MHz suggests it is capable of high clock speeds, but the memory subsystem cannot keep pace with the compute units.

Settings Recommendations

The measured FPS data suggests that the best experience for this combo depends heavily on the target resolution. At 1920x1080, the Medium preset offers the best balance, with an average of 91 FPS and a minimum of 78 FPS. This provides smooth gameplay well above the 60 FPS threshold while maintaining better visual quality than Low. The High preset at 76 FPS average is also viable, but the 15 FPS drop from Medium may not justify the visual improvements.

At 2560x1440, the Low preset is the only option that consistently exceeds 60 FPS, with an average of 92 FPS. The Medium preset averages 66 FPS but dips to 56 FPS minimum, which may cause occasional stutters in fast-paced boxing action. The High preset at 55 FPS average is borderline, and Ultra at 35 FPS is not recommended for competitive play. For the best experience at 1440p, Low settings are recommended, with Medium as a secondary option if the player accepts the minimum frame rate drops.

At 3840x2160, the situation is more challenging. The Low preset averages 58 FPS, which is below the 60 FPS target but still playable. The Medium preset averages 42 FPS with a 36 FPS minimum, which is likely too low for smooth gameplay. High and Ultra settings at 35 FPS and 22 FPS respectively are not viable for a good experience. The data indicates that 4K play is only possible at Low settings, and even then, the frame rate is marginal.

Overall, the recommended settings for this combo are Medium at 1080p and Low at 1440p. The 4K resolution should be avoided unless the player is willing to accept frame rates below 60 FPS. The Ultra preset is consistently the worst value, offering only marginal visual improvements over High while reducing FPS by 35-37% across all resolutions.

CPU Role

The AMD Ryzen 9 7900X is an exceptionally powerful processor that far exceeds the demands of Undisputed. With 12 cores and 24 threads based on the Zen 4 architecture, the CPU has a base clock of 4.70 GHz and a boost clock of 5.60 GHz. The 64 MB of shared L3 cache and 1 MB L2 cache per core provide ample data storage for game logic and physics calculations. The CPU's 91st percentile ranking among all processors, with an average benchmark score of 53288, places it well above the vast majority of CPUs in the database.

The CPU's synthetic benchmark results demonstrate its capabilities. In Cinebench R23, it scores 29300 in multicore and 2016.5 in singlecore. Geekbench scores are 19267 multicore and 2617 singlecore. These scores indicate strong single-threaded performance, which is important for game logic, and exceptional multi-threaded performance for background tasks and streaming. The CPU's nearest rivals in the database include the AMD EPYC 7313P (0.2% slower), Intel Xeon Phi 7290 (0.3% faster), Intel Xeon 634 (0.6% slower), and Intel Core i7-14700F (0.6% faster), all of which are high-end processors.

In Undisputed, the CPU's role is to handle the simulation of boxing matches, including fighter AI, physics calculations, and game state management. The 12-core, 24-thread configuration with a 5.60 GHz boost clock provides more than enough processing power for these tasks. The measured FPS data shows that the CPU is not the bottleneck at any resolution or setting, as the frame rates scale consistently with GPU load rather than CPU load. The CPU's 170 W TDP and 5 nm process node indicate a high-performance design that operates within its thermal envelope.

The CPU's memory support for DDR5 with dual-channel configuration provides 83.2 GB/s of bandwidth, which is shared with the GPU's system-shared memory. This arrangement means the CPU's memory performance directly impacts the GPU's ability to access data, creating an interesting dynamic where the CPU's memory bandwidth becomes a factor in GPU-bound scenarios. However, the CPU's 24 PCIe Gen 5 lanes are unused for graphics in this configuration, as the Arc B390 uses an IGP interface, further emphasizing the GPU's role as the limiting factor.
