Undisputed

The Intel Core i5-9400 paired with the AMD Radeon RX 6750 XT delivers a consistently playable experience in Undisputed, with the measured data showing that the combination’s performance scales predictably across resolutions and quality presets. The strongest balance between visual fidelity and frame rate appears at 1440p, where several presets exceed the 120 FPS threshold, while 4K remains viable only at lower settings. This analysis walks through the measured rows to identify the optimal preset, examines the GPU’s memory and clock contributions, answers common questions, and positions the combo within the broader tested field.

Settings Recommendations

At 3840x2160, the Ultra preset produces an average of 49.6 FPS, which is below the 60 FPS standard for smooth gameplay. Dropping to High raises the average to 78.4 FPS, a 58% improvement over Ultra, while Medium reaches 97.3 FPS and Low hits 135.2 FPS. For 4K displays, the data suggests that High is the sensible ceiling—it clears 60 FPS with a comfortable margin—while Medium offers a more responsive experience at 97.3 FPS without the visual degradation of Low.

At 2560x1440, the picture is far healthier. Ultra averages 78.6 FPS, which is playable but not ideal for fast-paced action. High jumps to 123.1 FPS, a 57% increase over Ultra, and Medium reaches 152.5 FPS. Low is the outlier at 208.7 FPS, but it sacrifices most graphical detail. For 1440p, the data points to High as the best experience: it stays above 120 FPS, which is a common target for high-refresh monitors, while retaining the visual quality that Medium and Low remove.

At 1920x1080, every preset exceeds 100 FPS. Ultra averages 109.1 FPS, High reaches 171.2 FPS, Medium hits 205.4 FPS, and Low peaks at 291 FPS. The gap between Ultra and High is 62.1 FPS, indicating a steep cost for the highest settings. Given that High already provides 171.2 FPS, it is the recommended preset for 1080p—it delivers well over double the refresh rate of a standard 60 Hz monitor and leaves headroom for demanding scenes. Ultra is only worth considering if the user prioritizes maximum visuals over frame rate, as its 109.1 FPS average is still smooth.

Across all resolutions, the pattern is consistent: High offers the best balance of image quality and performance. Medium is a fallback for 4K users who want higher frame rates, while Ultra is reserved for 1080p or 1440p users who accept lower FPS for maximum detail.

GPU Role

The AMD Radeon RX 6750 XT is the primary driver of frame rates in this combo, and its specifications explain the measured results. It features 12 GB of GDDR6 memory on a 192-bit bus, delivering 432.0 GB/s of bandwidth. This memory configuration is ample for Undisputed at all tested resolutions—even at 4K Ultra, the game does not appear to be memory-limited, as the 49.6 FPS result is more likely a compute or shading bottleneck than a capacity issue. The 12 GB capacity also ensures that texture streaming at High and Ultra settings does not cause stutter, which is consistent with the absence of min FPS data suggesting frame drops.

The GPU’s clock behavior is notable. The base clock is 2150 MHz, the game clock is 2495 MHz, and the boost clock reaches 2600 MHz. The measured FPS scaling between presets suggests that the GPU is able to maintain high clocks under load—for instance, at 1080p Low, the average of 291 FPS indicates the card is running near its boost ceiling, as the workload is light enough to avoid thermal or power throttling. At 4K Ultra, the 49.6 FPS result implies the GPU is heavily utilized, and the boost clock may be lower due to sustained load, but the data does not show a catastrophic drop.

The RX 6750 XT’s 2560 shading units and 160 texture mapping units provide the raw throughput for this game’s rendering. The 13.31 TFLOPS FP32 performance is sufficient to push High presets at 1440p past 120 FPS, as seen in the 123.1 FPS average. The GPU’s 64 ROPs handle pixel output, which is relevant at 4K where resolution demands more fill rate; the 78.4 FPS at 4K High demonstrates that the ROPs are adequate but not overprovisioned. The 40 ray accelerators are present, but Undisputed likely does not use ray tracing heavily, as the Ultra preset’s 49.6 FPS at 4K is more consistent with traditional rasterization load than with RT effects.

FAQ

*Q: What is the best resolution for this CPU-GPU combo in Undisputed?*

A: The data shows 2560x1440 as the sweet spot. At High settings, the combo averages 123.1 FPS, which is well above the 60 FPS threshold and suitable for high-refresh displays. At 3840x2160, High drops to 78.4 FPS, which is still playable but less headroom, while 1920x1080 exceeds 170 FPS at High.

*Q: Can this combo handle 4K gaming in Undisputed?*

A: Yes, but only at lower presets. The measured data shows 78.4 FPS at 4K High, 97.3 FPS at Medium, and 135.2 FPS at Low. The Ultra preset falls to 49.6 FPS, which is below ideal smoothness. Users targeting 4K should use High or Medium for a responsive experience.

Q: How does the RX 6750 XT’s 12 GB VRAM affect results?

A: The 12 GB GDDR6 memory with 432.0 GB/s bandwidth is sufficient for all tested settings. There is no evidence of VRAM exhaustion causing performance cliffs, as the frame rate scaling between presets is gradual. Even at 4K Ultra, the 49.6 FPS result is consistent with compute limits rather than memory spillover.

Q: Is the Ultra preset ever recommended for this combo?

A: Only at 1920x1080, where it averages 109.1 FPS—above the 60 FPS standard. At 2560x1440, Ultra averages 78.6 FPS, which is playable but not ideal. At 3840x2160, Ultra’s 49.6 FPS is too low for smooth gameplay, so it should be avoided.

Q: What frame rate can I expect at 1080p with High settings?

A: The measured average is 171.2 FPS. This is more than double the 60 FPS baseline and even exceeds 144 Hz displays. The Low preset reaches 291 FPS, but High provides a better visual experience with only a 119.8 FPS penalty.

Q: How does the CPU’s 6-core, 6-thread configuration impact results?

A: The Intel Core i5-9400 has 6 cores and 6 threads, with a boost clock of 4.10 GHz. In this data, the CPU does not appear to bottleneck the GPU at any resolution—the FPS scales consistently with resolution changes, indicating that the GPU is the limiting factor. Even at 1080p Low, where the CPU would be most stressed, the 291 FPS average suggests sufficient headroom.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 291 FPS, followed by Medium at 205.4 FPS, High at 171.2 FPS, and Ultra at 109.1 FPS. The differences between presets are substantial: moving from Low to Medium costs 85.6 FPS, from Medium to High costs 34.2 FPS, and from High to Ultra costs 62.1 FPS. The Ultra preset’s 109.1 FPS is still above 100 FPS, but the steep drop from High suggests that Ultra’s visual gains come at a high performance cost.

At 2560x1440, the frame rates remain strong. Low averages 208.7 FPS, Medium reaches 152.5 FPS, High hits 123.1 FPS, and Ultra drops to 78.6 FPS. The scaling is more linear here: Low to Medium is a 56.2 FPS reduction, Medium to High is 29.4 FPS, and High to Ultra is 44.5 FPS. The 78.6 FPS at Ultra is below the 120 FPS threshold but above 60 FPS, making it a borderline choice for competitive play.

At 3840x2160, the performance drops significantly. Low averages 135.2 FPS, Medium reaches 97.3 FPS, High hits 78.4 FPS, and Ultra falls to 49.6 FPS. The gap between Low and Medium is 37.9 FPS, Medium to High is 18.9 FPS, and High to Ultra is 28.8 FPS. The Ultra result is the only one below 60 FPS across all tested settings, confirming that 4K Ultra is beyond this combo’s practical range.

Comparing resolutions, the 1440p High result of 123.1 FPS is the most balanced point in the data—it is 44.7 FPS lower than 1080p High but 44.7 FPS higher than 4K High. The 1080p Low result of 291 FPS is the peak across all tests, while 4K Ultra at 49.6 FPS is the minimum.

How This Combo Ranks

In the database of tested combos for Undisputed, this pairing of Intel Core i5-9400 and AMD Radeon RX 6750 XT holds the 761st position out of 1580 combinations. This places it near the middle of the field—specifically, in the 48th percentile of tested combos. The rank reflects the GPU’s strong mid-range capability, but the CPU’s older architecture limits the overall score compared to modern processors.

The RX 6750 XT itself sits in the 79th percentile among all GPUs, with an average benchmark score of 35327. Its nearest rivals include the AMD Radeon RX 5600M (score 35264, 0.2% slower), the NVIDIA GeForce RTX 5070 Ti Mobile (score 35435, 0.3% faster), the AMD Radeon 880M (score 35646, 0.9% faster), and the NVIDIA GeForce RTX 3080 (score 35787, 1.3% faster). These small deltas indicate that the RX 6750 XT is closely grouped with several other GPUs, and its performance in Undisputed is consistent with this positioning—the measured FPS is strong but not top-tier.

The CPU, the Intel Core i5-9400, sits in the 50th percentile among all CPUs, with an average benchmark score of 2305. Its nearest rivals are the Intel Core i3-10305 (score 2300, 0.2% slower), the Intel Core i3-1125G4 (score 2299, 0.2% slower), the Intel Xeon E-2134 (score 2295, 0.4% slower), and the Intel Core i7-8809G (score 2319, 0.6% faster). The CPU’s mid-pack standing suggests it is not a performance outlier, and in Undisputed, the data confirms that the GPU drives the frame rate—the combo’s 761st rank out of 1580 is a reasonable outcome for a mid-range pairing.

CPU Role

The Intel Core i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, manufactured on a 14 nm process. Its base clock is 2.90 GHz, and it boosts to 4.10 GHz. The CPU has 9 MB of shared L3 cache, with 256 KB of L2 per core and 64 KB of L1 per core. It supports DDR4 memory in dual-channel configuration, with a memory bandwidth of 42.7 GB/s. This specification set is modest by modern standards, but it is sufficient for Undisputed, which is a sports title that does not appear to demand heavy multi-threading.

The measured FPS data shows no evidence of CPU bottlenecking. At 1080p Low, the average of 291 FPS is the highest across all tests, which indicates that the CPU can feed frames to the GPU at very high rates. If the CPU were the limiting factor, we would expect the FPS to plateau at a lower value regardless of resolution—but the data shows clear scaling from 1080p to 4K, which is a GPU-driven pattern. For instance, 1080p High averages 171.2 FPS, while 1440p High drops to 123.1 FPS and 4K High falls to 78.4 FPS. This consistent decline with increasing resolution confirms that the RX 6750 XT is the bottleneck, not the i5-9400.

The CPU’s 6 threads may be a limitation in other modern titles that utilize more than 6 threads, but in Undisputed, the single-core performance (Cinebench R23 single-core score of 1125) is adequate. The multi-core score of 7969 in Cinebench R23 shows that the CPU can handle moderate parallel workloads, but the game’s engine appears to rely more on GPU throughput. The 65 W TDP and PCIe Gen 3 interface are not performance constraints in this data—the combo achieves its expected mid-range results without any sign of CPU-induced frame pacing issues.
