Undisputed

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread desktop processor built on the Zen 4 architecture (Phoenix codename) using TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, drawing a 65 W TDP. This CPU sits on the AMD Socket AM5 platform and supports dual-channel DDR5 memory with a bandwidth of 83.2 GB/s. The cache hierarchy consists of 64 KB L1 per core, 1 MB L2 per core, and a shared 16 MB L3 cache.

For a sports title like Undisputed, the CPU's single-threaded performance is often the primary driver of frame pacing, as the game's simulation and physics logic typically run on a limited number of threads. The Ryzen 5 8400F scores 951 in the 3dmark_single_thread test and 1,874 in the 3dmark_2_threads test. These scores suggest strong per-core throughput, which is essential for maintaining high average FPS when the GPU is not the bottleneck. The multi-threaded scores (6,091 in 3dmark_16_threads and 6,165 in max_threads) indicate that the 12 threads are more than sufficient for this genre, which rarely scales beyond a handful of cores.

The CPU's overall performance profile places it at the 82nd percentile among all CPUs, with an average benchmark score of 25,064. Its closest rivals in aggregate performance include the AMD Ryzen 7 2700X (score 25,057, delta 0%) and the AMD Ryzen 5 7500F (score 24,993, delta 0.3%). This means the 8400F is statistically tied with these parts in synthetic workloads, though the 7500F is a similarly modern Zen 4 chip. The 8400F's 4 nm process and 25,000 million transistors on a 178 mm² die enable efficient performance, but the 16 MB L3 cache is relatively modest, which can impact certain gaming scenarios that rely on large datasets.

In Undisputed, the CPU's role becomes evident when examining the measured FPS at lower resolutions. At 1080p Low settings, the combo achieves 460.7 FPS, which far exceeds the refresh rate of most displays and indicates that the CPU is capable of feeding the GPU at extreme rates. However, as settings increase to Ultra at 1080p, the average FPS drops to 178.3, suggesting a shift toward GPU-bound rendering. The CPU's 6-core configuration with 12 threads is ample for this game, and the benchmark results show no signs of thread starvation.

FAQ

Q: How does the CPU's memory bandwidth compare to its L3 cache size for gaming?

A: The 83.2 GB/s memory bandwidth is substantial for a dual-channel DDR5 setup, but the 16 MB L3 cache is on the smaller side for modern CPUs. In Undisputed, this combination works well, as the game does not appear to require massive cache residency, evidenced by the high FPS at 1080p.

How This Combo Ranks

The combination of the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 5070 Ti ranks 138th out of 1,580 tested combos in Undisputed. This places the pairing in the top 9% of all configurations tested, a strong showing for a mid-range CPU paired with a high-end GPU. The rank reflects the balance between the CPU's capable 6-core design and the GPU's substantial rendering power.

In context, the 8400F's 82nd percentile CPU ranking and the RTX 5070 Ti's 87th percentile GPU ranking suggest that the combo is slightly GPU-limited in aggregate, but the FPS data reveals a more nuanced picture. At 1080p Low, the combo achieves 460.7 FPS, which is so high that the CPU becomes the limiting factor. At 4K Ultra, the average drops to 81.6 FPS, which is clearly GPU-bound. The rank of 138 indicates that this pairing is well-matched for high-refresh-rate gaming at 1440p and playable 4K, but it is not the absolute top combo due to the CPU's modest core count and cache size.

The percentile rankings of the individual components (82nd for CPU, 87th for GPU) align with the combo's top-9% placement. This suggests that the CPU is not dragging down the GPU significantly in most scenarios. However, at 1080p Low, the 460.7 FPS result shows the CPU's ceiling is higher than the GPU can exploit at lower settings, which is a typical characteristic of a balanced mid-range processor paired with an enthusiast-tier graphics card.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. All results are measured averages, with no min or max FPS recorded.

1080p (1920x1080):

• Low: 460.7 FPS
• Medium: 326.9 FPS
• High: 275.3 FPS
• Ultra: 178.3 FPS

1440p (2560x1440):

• Low: 332.8 FPS
• Medium: 239.9 FPS
• High: 195.7 FPS
• Ultra: 126.3 FPS

4K (3840x2160):

• Low: 209.4 FPS
• Medium: 153.9 FPS
• High: 125.6 FPS
• Ultra: 81.6 FPS

At 1080p, the jump from Low to Ultra represents a 61% reduction in average FPS (460.7 to 178.3). This is a significant scaling factor, indicating that the Ultra preset introduces heavy rendering effects that stress the GPU. The 1080p Low result of 460.7 FPS is the highest recorded in the entire dataset, suggesting that the CPU is the primary driver at this setting, as the GPU has minimal work to do.

At 1440p, the Ultra preset delivers 126.3 FPS, which is still well above 60 FPS and suitable for high-refresh-rate monitors. The difference between Low and Ultra at 1440p is 206.5 FPS (332.8 to 126.3), a 62% drop that mirrors the 1080p scaling pattern. This indicates that the GPU is becoming more of a bottleneck as resolution increases, but the CPU still provides enough headroom to keep frame rates high.

At 4K, the Ultra preset drops to 81.6 FPS, which is the only result below 100 FPS in the entire dataset. The Low preset at 4K still achieves 209.4 FPS, showing that the GPU is capable of handling the resolution when settings are reduced. The scaling from Low to Ultra at 4K is a 61% reduction (209.4 to 81.6), consistent with the other resolutions, but the absolute values are lower due to the increased pixel count.

Resolution Scaling

The FPS drop from 1080p to 4K reveals the limiting component at each resolution. At Low settings, the 1080p result is 460.7 FPS, which drops to 209.4 FPS at 4K — a 54.5% reduction. This indicates that even at Low settings, the GPU is heavily utilized as resolution increases, but the CPU's strong single-threaded performance keeps the 1080p result extremely high.

At Ultra settings, the 1080p result is 178.3 FPS, which drops to 81.6 FPS at 4K — a 54.2% reduction. This consistent scaling pattern across all settings (approximately 54-55% reduction from 1080p to 4K) suggests that the frame rate is primarily limited by the GPU's pixel throughput, not by the CPU. The RTX 5070 Ti's 896.0 GB/s memory bandwidth and 96 ROPs are likely the key factors in this scaling behavior.

The data shows that the CPU is the limiting component only at 1080p Low, where the 460.7 FPS result exceeds what most GPUs can sustain. At all other settings and resolutions, the GPU is the bottleneck. This is evidenced by the fact that the 4K Ultra result (81.6 FPS) is 43% of the 1080p Low result (460.7 FPS), which aligns with the 4x pixel count increase from 1080p to 4K. If the CPU were the primary limiter, the FPS drop would be less severe when moving to higher resolutions, but the data shows a near-linear relationship with pixel count.

The RTX 5070 Ti's 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, which is sufficient for 4K gaming, as evidenced by the 209.4 FPS at Low settings. However, the Ultra preset's heavy use of shading units (8,960) and texture units (280) pushes the GPU to its limits, resulting in the 81.6 FPS figure. The CPU's 83.2 GB/s memory bandwidth is not a limiting factor, as the game's data footprint fits within the 16 MB L3 cache for most operations.

In summary, this combo is GPU-limited in Undisputed at all settings above 1080p Low. The Ryzen 5 8400F provides enough single-threaded performance to avoid becoming a bottleneck, while the RTX 5070 Ti's architecture determines the scaling behavior. The result is a pairing that delivers excellent frame rates at all tested resolutions, with the caveat that 4K Ultra is the only setting that dips below 100 FPS.
