# Undisputed with AMD Ryzen 5 7400F + Intel Arc B390

The AMD Ryzen 5 7400F paired with the Intel Arc B390 delivers a playable but constrained experience in Undisputed, with the combo landing at rank 2491 out of 2813 tested configurations. The CPU is a strong modern six-core Zen 4 part, but the GPU—an integrated Arc solution with shared system memory—becomes the decisive bottleneck at higher resolutions and settings. Benchmark results show that 1080p Low is the only configuration that clears 120 FPS, while 4K Ultra drops to just 22 FPS, indicating a system that demands careful settings management to remain competitive.

Settings Recommendations

The measured data across three resolutions and four quality presets paints a clear picture: the sweet spot for this combo is 1080p Medium, which delivers an average of 91 FPS with a minimum of 78 FPS and a maximum of 105 FPS. This setting provides a meaningful jump over High (76 FPS average) while staying well above the 60 FPS threshold for smooth gameplay. The minimum frame rate of 78 FPS ensures that even demanding scenes with multiple boxers on screen won't dip into stutter territory.

For players prioritizing maximum fluidity over visual fidelity, 1080p Low is the standout choice, achieving 127 FPS average—the only measured result above 120 FPS. This is the configuration for competitive play or high-refresh-rate displays. However, the transition from Low to Medium costs 36 FPS (a 28% drop), which suggests the GPU is heavily taxed by even modest quality increases.

At 1440p, Medium settings (66 FPS average, 56 FPS minimum) offer the best balance between resolution clarity and smoothness. High settings at 1440p drop to 55 FPS average, which is borderline for a sports title that benefits from consistent frame pacing. The 1440p Low preset, at 92 FPS average, is a viable alternative for users who want higher resolution without sacrificing responsiveness.

4K is not recommended for this combo. Even at Low settings, the average FPS is 58, which is below the ideal 60 FPS threshold for most displays. The 4K Medium result (42 FPS average, 36 FPS minimum) shows frame times that will be noticeable, and 4K High (35 FPS) and 4K Ultra (22 FPS) are effectively unplayable. The data indicates that this integrated GPU solution lacks the memory bandwidth and compute throughput for 4K gaming in Undisputed.

How This Combo Ranks

With a combo rank of 2491 out of 2813 tested combinations, this system sits in the bottom 11% of all configurations tested in Undisputed. This places it firmly in the lower quartile, indicating that the vast majority of gaming PCs will outperform it. The ranking reflects the GPU's severe limitations rather than CPU deficiencies—the Ryzen 5 7400F is a capable processor, but the Arc B390's integrated nature and shared memory architecture hold the system back.

The CPU itself ranks in the 83rd percentile against all processors, with an average benchmark score of 32750. Its nearest rivals include the Intel Core i5-14600T (32707, 0.1% ahead), Intel Core Ultra 7 155H (32697, 0.2% ahead), AMD Ryzen 7 PRO 6850H (32812, 0.2% behind), and AMD Ryzen AI 7 PRO 360 (32662, 0.3% ahead). These are all within a hair's breadth of performance, confirming that the 7400F is a well-balanced mid-range CPU.

The GPU tells a different story. The Arc B390 scores 1482 in 3DMark Steel Nomad, placing it in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX (1463, 1.3% behind), GeForce 800M (1460, 1.5% behind), GT 625 OEM (1446, 2.5% behind), and GT 710 (1443, 2.7% behind). These are all entry-level or legacy discrete GPUs, and the fact that an integrated solution trades blows with them underscores the performance tier this combo occupies.

The rank disparity between CPU and GPU explains the system's overall position: a modern CPU shackled to a GPU that performs at roughly the level of decade-old discrete graphics. In Undisputed, this manifests as a system that can handle the game's physics and AI calculations easily but struggles with the rendering workload at higher settings.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel's 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster operation units, along with 12 ray tracing cores. The GPU operates at a base clock of 300 MHz with a boost clock of 2500 MHz, delivering a pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s. Floating-point performance is rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 (2:1 ratio).

The most critical limitation is the memory configuration: the Arc B390 uses System Shared memory, meaning it draws from the system's DDR5 RAM rather than dedicated VRAM. Memory bandwidth is listed as "System Dependent," and the bus width is also shared. This architecture creates a fundamental bottleneck for gaming, as the GPU competes with the CPU for memory access. In Undisputed, this manifests as significant FPS drops when settings increase, since higher quality presets demand more texture memory and bandwidth.

The 80 W TDP and IGP form factor (no power connectors, portable device dependent display outputs) confirm this is not designed for serious gaming workloads. DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 API support are present, but the hardware simply lacks the throughput for demanding titles at high resolutions.

The 3DMark Steel Nomad score of 1482 places this GPU at the 9th percentile, and its nearest rivals are all NVIDIA GT-series or 800M parts from years past. This positioning explains why Undisputed frame rates drop so precipitously from 1080p Low (127 FPS) to 4K Ultra (22 FPS)—the GPU's compute and memory resources are exhausted quickly as resolution and quality scale up.

Measured FPS Breakdown

1080p (1920x1080): The best-case scenario for this combo. Low settings produce 127 FPS average, which is the only triple-digit result in the entire dataset. Medium settings deliver 91 FPS average with a minimum of 78 FPS and maximum of 105 FPS, showing solid frame pacing. High settings drop to 76 FPS average, still playable but with less headroom. Ultra settings fall to 49 FPS average, which is below the 60 FPS threshold and will exhibit noticeable judder.

1440p (2560x1440): A significant step down from 1080p. Low settings yield 92 FPS average, which is respectable but 35 FPS lower than the same settings at 1080p. Medium settings produce 66 FPS average (56 FPS minimum, 76 FPS maximum), crossing the 60 FPS line but with minimums that dip below it. High settings drop to 55 FPS average, and Ultra falls to 35 FPS average—a 44% reduction from Medium.

4K (3840x2160): This resolution is largely unplayable with this combo. Low settings manage 58 FPS average, just short of the 60 FPS target. Medium settings drop to 42 FPS average (36 FPS minimum, 48 FPS maximum), showing significant frame time variance. High settings produce 35 FPS average, and Ultra bottoms out at 22 FPS average—a slideshow by any measure.

The scaling across settings at each resolution is consistent: Low to Medium typically costs 25-30% of performance, Medium to High costs another 20-25%, and High to Ultra costs an additional 30-35%. This consistent degradation pattern indicates that the GPU is the limiting factor, as each quality tier adds proportional rendering load that the Arc B390 cannot absorb.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals the system's bottleneck. At Low settings, moving from 1080p (127 FPS) to 1440p (92 FPS) represents a 28% reduction, and then to 4K (58 FPS) a further 37% reduction from 1440p. The total drop from 1080p to 4K at Low settings is 54%.

At Medium settings, the progression is 91 FPS (1080p) → 66 FPS (1440p) → 42 FPS (4K), with drops of 27% and 36% respectively—a total 54% reduction. The consistency of these percentage drops across settings indicates that resolution scaling is governed by the GPU's fill rate and memory bandwidth, both of which are severely constrained in this integrated solution.

The pixel count increases by 78% from 1440p to 4K, yet the FPS drop at Medium settings is only 36%, suggesting that the game becomes partially CPU-bound at lower resolutions. This is corroborated by the fact that at 1080p Low, the system achieves 127 FPS—a rate that requires strong CPU performance, which the Ryzen 5 7400F provides with its 6 cores, 12 threads, and 4.70 GHz boost clock. However, as resolution increases, the GPU's limitations dominate, and the FPS drops become more pronounced relative to the pixel count increase.

The data indicates that this combo is CPU-sufficient but GPU-deficient. At 1080p, the Ryzen 5 7400F can feed frames faster than the Arc B390 can render them, resulting in the GPU being the bottleneck. At 4K, both components are overwhelmed, but the GPU fails first, as evidenced by the 22 FPS Ultra result. The 32 MB of shared L3 cache on the CPU and 83.2 GB/s memory bandwidth help at lower resolutions, but the system shared GPU memory negates these advantages as resolution scales.

For users targeting 1440p or 4K, the data clearly shows diminishing returns. The 1440p Medium result (66 FPS) is the highest quality-to-performance ratio at that resolution, but it still falls short of the smoothness available at 1080p. The 4K results, regardless of settings, fail to reach consistently playable frame rates.
