Undisputed

The AMD Ryzen 9 7900X paired with the AMD Radeon RX 580 produces a performance profile dominated by the graphics card in Undisputed. Across all tested resolutions, the RX 580 is the primary constraint, with the high-end 12-core CPU providing ample headroom that goes largely unused. The data reveals a system that can deliver smooth frame rates at 1080p but struggles significantly at higher resolutions, making it a clear candidate for resolution-specific settings adjustments.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep and consistent, confirming that the GPU is the limiting component in this combination. At High settings, the average frame rate falls from 73 FPS at 1920x1080 to 53 FPS at 2560x1440, a reduction of 20 FPS. Moving to 3840x2160, the average drops further to 33 FPS, representing a 40 FPS loss compared to 1080p. This scaling pattern—roughly a 27% decrease from 1080p to 1440p and a 55% decrease from 1080p to 4K—indicates that the RX 580's 256-bit memory interface and 6.175 TFLOPS of FP32 compute are being saturated as pixel count rises.

The trend holds across all settings presets. On Low, the system manages 122 FPS at 1080p, which drops to 88 FPS at 1440p and 56 FPS at 4K. The Medium preset shows a similar trajectory: 88 FPS at 1080p, 64 FPS at 1440p, and 40 FPS at 4K. Even the most demanding Ultra preset, which starts at a modest 47 FPS at 1080p, falls to 34 FPS at 1440p and bottoms out at 21 FPS at 4K. The consistent proportional drops across all four presets strongly suggest that the limiting factor is raw pixel throughput rather than any specific game setting.

What this resolution scaling reveals is that the CPU is not a bottleneck at any point. The Ryzen 9 7900X, with its 12 cores and 24 threads boosting to 5.60 GHz, is more than capable of feeding the GPU at even the lowest resolution tested. The fact that 1080p Low produces 122 FPS while 4K Low produces only 56 FPS—a 66 FPS difference—demonstrates that the game's performance is entirely contingent on the RX 580's ability to render pixels, not on the CPU's processing speed. Users seeking higher frame rates at 1440p or 4K would need to lower settings dramatically, but even then, the ceiling is limited by the GPU's 1340 MHz boost clock and 8 GB of GDDR5 memory.

How This Combo Ranks

In the broader context of all tested hardware combinations for Undisputed, this pairing ranks near the bottom. The combo holds position 3386 out of 3718 tested combos, placing it in the 9th percentile of all systems. This low ranking is unsurprising given the significant mismatch between the CPU and GPU. The Ryzen 9 7900X is an elite processor, ranking in the 91st percentile against all CPUs, while the RX 580 sits in the 53rd percentile against all GPUs. The combination of a top-tier CPU with a mid-to-low-tier GPU creates a system that underperforms relative to what the processor alone would suggest.

The data shows that this combo's ranking is pulled down almost entirely by the GPU. The CPU's average benchmark score of 53,288 places it just 0.2% ahead of the AMD EPYC 7313P and 0.6% ahead of the Intel Xeon 634, but these are server-class processors with different design goals. In gaming, the 7900X's high single-thread performance—evidenced by its 2,617 Geekbench single-core score and 4,238 Passmark single-thread score—should theoretically support high frame rates. However, the RX 580's average benchmark score of 12,928 puts it just 0.1% behind the NVIDIA GeForce RTX 3050 Ti Mobile and 0.4% behind the NVIDIA GeForce GTX 1660 SUPER, both of which are similarly constrained in modern titles.

The rank of 3386 out of 3718 means that roughly 91% of tested combos deliver better frame rates in Undisputed. This is a direct consequence of the GPU's 8 GB VRAM capacity and 14 nm process node, which limit its ability to handle the game's demands at higher resolutions. The CPU's contribution to this ranking is minimal; swapping in a much weaker processor would likely produce nearly identical results, as the game never appears to stress the 7900X beyond a fraction of its capacity.

GPU Role

The AMD Radeon RX 580 is the decisive component in this system, and its specifications explain the measured frame rates. Based on the Polaris 20 chip on a 14 nm process, this GPU features 2,304 shading units, 144 texture mapping units, and 32 ROPs. Its clock speeds are modest by modern standards, with a base of 1257 MHz and a boost of 1340 MHz. The 8 GB of GDDR5 memory on a 256-bit bus provides 256.0 GB/s of bandwidth, which is adequate for 1080p gaming but becomes a limiting factor at higher resolutions.

The GPU's performance in Undisputed is best understood through its benchmark scores. The Passmark G3D score of 8,813 and the 3DMark Steel Nomad DX12 score of 1,005 both place this GPU in a performance class that is roughly equivalent to entry-level gaming hardware from several years ago. The Vulkan score of 45,173 and OpenCL score of 37,453 from Geekbench confirm that while the GPU can handle compute tasks, its raw graphics throughput is insufficient for demanding modern titles at high settings.

The 8 GB VRAM is sufficient for 1080p gaming, as evidenced by the 122 FPS average on Low settings at that resolution. However, the memory bandwidth becomes a bottleneck at 1440p and 4K, where the frame rates drop precipitously. The GPU's 42.88 GPixel/s pixel rate and 193.0 GTexel/s texture rate are simply not enough to maintain smooth performance at 4K, where even Low settings only produce 56 FPS. The fact that the GPU is rated at 185 W TDP with a 450 W suggested PSU indicates it was designed for mid-range systems, and its end-of-life production status suggests it is not intended to handle the demands of contemporary sports titles at high resolutions.

Measured FPS Breakdown

The measured frame rates provide a complete picture of this combo's capabilities in Undisputed. At 1920x1080, the system delivers playable performance across all settings. Low settings produce an average of 122 FPS, which is well above the threshold for smooth gameplay. Medium settings yield 88 FPS with a minimum of 75 FPS and a maximum of 101 FPS, indicating consistent frame pacing. High settings drop to 73 FPS, still acceptable for most players. Ultra settings, however, fall to 47 FPS, which may feel less smooth in fast-paced boxing action.

At 2560x1440, performance degrades noticeably. Low settings produce 88 FPS, which is acceptable but significantly lower than at 1080p. Medium settings average 64 FPS with a minimum of 54 FPS and a maximum of 73 FPS, placing the experience in a playable but not ideal range. High settings drop to 53 FPS, which is marginal for a sports title that benefits from higher frame rates. Ultra settings fall to 34 FPS, which is likely too low for competitive or immersive play.

The 3840x2160 results are largely disappointing. Low settings produce 56 FPS, which is borderline playable but not smooth. Medium settings average 40 FPS with a minimum of 34 FPS and a maximum of 46 FPS, indicating frequent dips below the 60 FPS threshold. High settings fall to 33 FPS, and Ultra settings bottom out at 21 FPS, both of which are below the minimum for acceptable gameplay. The data clearly shows that this combo is not suited for 4K gaming in Undisputed.

Settings Recommendations

Based on the measured rows, the optimal experience for this combo is at 1920x1080 with Medium settings. This configuration delivers an average of 88 FPS with a minimum of 75 FPS, providing a smooth and consistent experience that maximizes visual quality without sacrificing performance. The 75 FPS minimum ensures that even during intense combat sequences, the frame rate does not drop to a level that would cause noticeable stuttering.

For users prioritizing frame rate over visual fidelity, 1080p Low is the best choice, offering 122 FPS average. This setting is ideal for competitive play where responsiveness is paramount. However, the visual downgrade may be too severe for some players, making Medium the balanced recommendation.

At 1440p, Medium settings are the only viable option for a playable experience, averaging 64 FPS with a 54 FPS minimum. While this is playable, it is not ideal, and users may prefer to drop to Low settings for 88 FPS if smoothness is more important than visual quality. High and Ultra settings at 1440p should be avoided, as they produce frame rates below 60 FPS.

At 4K, only Low settings provide a remotely playable experience at 56 FPS. However, even this is marginal, and users with 4K displays should consider reducing their resolution to 1440p for a significantly better experience. Medium, High, and Ultra settings at 4K all produce frame rates below 60 FPS, making them unsuitable for gameplay.

CPU Role

The AMD Ryzen 9 7900X plays a minimal role in this combo's Undisputed performance, as the game does not appear to be CPU-intensive. The processor's 12 cores and 24 threads, based on the Zen 4 architecture on a 5 nm process, provide far more computational power than this game requires. The 4.70 GHz base clock and 5.60 GHz boost clock ensure that even single-threaded workloads are handled with ease, as evidenced by the 2,617 Geekbench single-core score and 1,093 3DMark single-thread score.

The CPU's benchmark results reinforce its capability. The Cinebench R23 multicore score of 29,300 and single-core score of 2,016.5 demonstrate exceptional performance across both multi-threaded and single-threaded tasks. The Passmark multithread score of 51,406 and single-thread score of 4,238 further confirm that this is a top-tier processor. However, in Undisputed, these capabilities are largely untapped, as the game's performance is constrained by the GPU at all tested settings.

The 64 MB of shared L3 cache and 83.2 GB/s memory bandwidth provide ample data throughput for the game's physics and AI calculations. The CPU's 91st percentile ranking against all CPUs, with an average benchmark score of 53,288, places it just 0.2% ahead of the AMD EPYC 7313P and 0.6% ahead of the Intel Xeon 634. Yet in this specific game, the CPU's influence on frame rates is negligible. The data shows that the frame rates are nearly identical to what would be expected from a much less powerful processor paired with the same GPU, confirming that the RX 580 is the sole bottleneck. Users should not expect any CPU upgrade to improve Undisputed performance with this GPU, as the processor is already operating far below its capacity.
