Undisputed

Resolution Scaling

The measured frame rates for Undisputed with this AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4090 combination show a clear pattern of GPU-bound scaling as resolution increases. At 1080p with Low settings, the system delivers 528.4 FPS, which drops to 381.7 FPS at 1440p and further to 246 FPS at 4K. This represents a 53.5% reduction from 1080p to 4K at Low settings, indicating that the RTX 4090 is still the primary limiting factor even at the highest resolution tested.

The High preset tells a similar story with different magnitudes. At 1080p High, the system achieves 318.5 FPS, falling to 230 FPS at 1440p and 143.6 FPS at 4K. The drop from 1080p to 4K at High settings is 54.9%, nearly identical to the Low preset's scaling. This consistency suggests that the game's rendering load scales predictably with pixel count, and the GPU's 24 GB of GDDR6X memory with 1.01 TB/s bandwidth is sufficient to avoid any memory-related bottlenecks across all tested configurations.

Ultra settings reveal the most dramatic scaling curve. At 1080p Ultra, the system produces 205.5 FPS, which decreases to 145.8 FPS at 1440p and 95.7 FPS at 4K. The 4K Ultra result represents a 53.4% reduction from the 1080p Ultra figure. Interestingly, the percentage drop is remarkably consistent across all presets, hovering around 53-55% when moving from 1080p to 4K. This uniformity indicates that the resolution scaling is primarily driven by pixel throughput rather than by any particular setting's computational cost.

The data shows that at 1080p Low, the frame rate of 528.4 FPS is so high that the CPU's role becomes more prominent. The Ryzen 5 8400F's 6 cores and 12 threads with a boost clock of 4.70 GHz must feed frames to the RTX 4090 at an extremely rapid pace. The fact that the system still achieves over 500 FPS at 1080p Low suggests the CPU is keeping pace adequately, though the scaling from 1080p to 1440p at Low (528.4 to 381.7 FPS, a 27.8% drop) hints that both components are working near their limits in this configuration.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture with a 4 nm process node. Its base clock of 4.20 GHz and boost clock of 4.70 GHz place it in a competitive position for gaming workloads. In synthetic benchmarks, this CPU achieves a Cinebench R23 multicore score of 20,851 and a single-core score of 2,943. The 3DMark single-thread score of 951 and 16-thread score of 6,091 provide additional context for its threading capabilities.

In Undisputed, a sports title, the CPU's role is primarily to maintain consistent frame pacing and handle game logic. The benchmark results indicate that at 1080p Low, the system produces 528.4 FPS, which is likely near the CPU's practical limit for this game. The 3DMark 2-thread score of 1,874 and 4-thread score of 3,563 suggest that the processor's single-thread performance is adequate for the game's core simulation tasks. The 16 MB of shared L3 cache and 83.2 GB/s memory bandwidth provide sufficient data throughput for the CPU to feed the GPU without becoming a bottleneck at standard resolutions.

Comparing the CPU to its nearest rivals, the Ryzen 5 8400F's average benchmark score of 25,064 places it nearly identical to the AMD Ryzen 7 2700X (25,057, 0% delta) and the AMD Ryzen 5 7500F (24,993, 0.3% delta). It trails the AMD Ryzen AI 5 PRO 340 by 0.1% (25,099) and the AMD EPYC 9474F by 0.2% (25,103). This tight grouping indicates that the 8400F's computational throughput is well-matched to its peers, though none of these processors are specifically optimized for gaming beyond their general-purpose capabilities.

The CPU's percentile ranking of 82 against all processors places it in the upper quintile, which aligns with its observed behavior in Undisputed. At 1080p High, the 318.5 FPS result shows that the CPU can still supply frames faster than most displays can refresh. However, the jump from 1080p High (318.5 FPS) to 1440p High (230 FPS) represents a 27.8% decrease, which is larger than the pixel count increase of 77% from 1080p to 1440p. This disproportionate drop suggests that the CPU is beginning to influence results at lower resolutions, where the GPU has more headroom.

GPU Role

The NVIDIA GeForce RTX 4090 represents the flagship of the GeForce 40-series, built on the Ada Lovelace architecture with a 5 nm process. Its 24 GB of GDDR6X memory on a 384-bit bus provides 1.01 TB/s of bandwidth, which is more than sufficient for Undisputed's texture and geometry demands at any resolution. The GPU's boost clock of 2520 MHz and 82.58 TFLOPS of FP32 compute power drive the high frame rates observed across all settings.

The GPU's PassMark G3D score of 38,194 and 3DMark Steel Nomad DX12 score of 9,223 demonstrate its raw rendering capability. In Undisputed, this translates to 4K Ultra performance of 95.7 FPS, which is above the 60 FPS threshold for smooth gameplay on high-refresh-rate displays. At 4K High, the 143.6 FPS result shows substantial headroom even at the highest resolution tested. The GPU's percentile ranking of 91 against all GPUs places it in the top decile, consistent with its observed performance.

The RTX 4090's nearest rivals in benchmark scores include the NVIDIA Tesla T4 (66,733, -0.4% delta) and the AMD Radeon Pro Vega 56 (67,097, -0.9% delta). The GPU's average benchmark score of 66,473 places it slightly below these workstation-oriented cards, though the gaming-focused architecture of the RTX 4090 with its 16,384 shading units and 512 tensor cores provides superior real-world gaming performance. The 128 RT cores and 512 TMUs contribute to the GPU's ability to handle complex rendering workloads in Undisputed.

The VRAM capacity of 24 GB ensures that even at 4K Ultra, the game's assets remain fully resident in graphics memory. The measured 4K Ultra frame rate of 95.7 FPS, compared to 4K High at 143.6 FPS, represents a 33.4% reduction when moving from High to Ultra. This indicates that the Ultra preset introduces significant additional rendering costs, likely through increased shadow quality, post-processing effects, and draw distances, all of which the RTX 4090 handles without memory-related stuttering.

Settings Recommendations

Based on the measured frame rates, the Ultra preset at 1440p provides the best balance of visual quality and performance. At 2560x1440 Ultra, the system produces 145.8 FPS, which comfortably exceeds the 144 Hz refresh rate of most gaming monitors. This configuration allows for full visual fidelity without sacrificing smoothness. For users with 4K displays, the High preset at 3840x2160 delivers 143.6 FPS, making it the recommended choice for 4K gaming. The 4K Ultra preset at 95.7 FPS remains playable and is suitable for users prioritizing visual quality over maximum frame rates.

At 1080p, the Ultra preset at 205.5 FPS is the clear recommendation, as it provides the best visual quality while still maintaining frame rates well above what any current display can show. The Medium preset at 1080p (385.1 FPS) and 1440p (273.4 FPS) offers diminishing returns in visual quality for only modest frame rate gains. The Low preset, while achieving 528.4 FPS at 1080p and 246 FPS at 4K, should be avoided due to the significant visual compromises it imposes, particularly since the system has ample GPU headroom at all resolutions.

The data shows that the High preset offers the most consistent experience across all resolutions. At 1080p High (318.5 FPS), 1440p High (230 FPS), and 4K High (143.6 FPS), the system maintains a minimum of 143.6 FPS even at the highest resolution. This consistency makes High the most versatile preset for users who may switch between displays or resolutions. The Ultra preset's 4K performance of 95.7 FPS, while above 60 FPS, introduces a noticeable step down from the High preset's 4K performance, suggesting that the visual differences between High and Ultra may not justify the 33.4% frame rate reduction for most users. For competitive play where maximum frame rates are paramount, the Medium preset at 1440p (273.4 FPS) or 1080p (385.1 FPS) provides an excellent compromise between visual quality and responsiveness.
