Valorant

Valorant is a lightweight tactical FPS that scales in a very specific way with the Intel Core i5-10400F and AMD Radeon RX 6600 combination. The measured data shows a system that is heavily CPU-bound at lower resolutions, with the GPU only becoming a meaningful factor when pushing 4K. The average frame rates across all tested settings and resolutions are exceptionally high, ranging from 224.1 FPS at 4K Ultra to 388.3 FPS at 1080p Low. This indicates that the pairing is more than capable of driving high-refresh-rate monitors, though the bottleneck shifts depending on where you set the resolution slider. The following sections break down the scaling behavior, component roles, and optimal settings based strictly on the measured rows.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial but not catastrophic, revealing a clear shift in the limiting component. At Low settings, the average FPS falls from 388.3 at 1920x1080 to 365 at 2560x1440, then to 341.2 at 3840x2160. That is a total drop of 47.1 FPS, or roughly 12.1% when moving from 1080p to 4K. This relatively modest decline suggests that at Low settings, the CPU is still the primary constraint even at 4K, as the RX 6600 has enough headroom to handle the lighter pixel load.

The scaling picture changes when you raise the quality preset. At High settings, the average FPS drops from 326.2 at 1080p to 292.4 at 1440p, and then to 230.7 at 4K. The gap between 1440p and 4K here is 61.7 FPS, which is significantly larger than the 33.8 FPS gap between 1080p and 1440p. This disproportionate decline indicates that the GPU begins to take over as the bottleneck at 4K High, as the Radeon RX 6600’s rendering load increases with the higher resolution and more demanding effects.

The Ultra preset shows the most pronounced resolution sensitivity. The average FPS drops from 317.2 at 1080p to 277.9 at 1440p, and then to 224.1 at 4K. The total decline from 1080p to 4K is 93.1 FPS, which is the largest absolute drop among all settings. This confirms that Ultra settings place the most stress on the GPU, making the 4K Ultra configuration the only tested scenario where the graphics card is unequivocally the limiting factor. The data suggests that for 1080p and 1440p gaming, the i5-10400F is the primary driver of performance, while the RX 6600 only becomes the clear bottleneck at 4K with higher presets.

GPU Role

The AMD Radeon RX 6600 is a RDNA 2.0 part with 8 GB of GDDR6 memory on a 128-bit bus, delivering a bandwidth of 224.0 GB/s. Its boost clock sits at 2491 MHz, with a game clock of 2044 MHz. The card features 1792 shading units, 112 texture mapping units, and 64 raster output units. In the context of Valorant, these specifications are more than sufficient, as the game does not heavily tax VRAM capacity. The 8 GB frame buffer is never a concern at any of the tested resolutions, as even 4K Ultra stays comfortably within that limit.

The GPU’s raw compute performance is rated at 8.928 TFLOPS FP32, which is substantial for a game like Valorant that relies more on draw call efficiency than brute pixel throughput. The measured results reflect this: at 1080p Medium, the system achieves 327.8 FPS, which is only 1.6 FPS higher than the 1080p High result of 326.2 FPS. This near-identical performance across Medium and High at 1080p indicates that the GPU is not the limiting factor at these settings, as the CPU is able to feed frames faster than the GPU can render them.

However, the GPU’s role becomes more apparent at 4K. The difference between 4K Low (341.2 FPS) and 4K High (230.7 FPS) is 110.5 FPS, showing that the RX 6600’s rendering pipeline is stressed by the higher resolution combined with more complex shading. The card’s 64 ROPs and 159.4 GPixel/s pixel rate are adequate for 4K in Valorant, but the gap between Low and High at 4K demonstrates that the GPU’s fill rate and shader throughput do matter when you push the resolution. The benchmark results indicate that the RX 6600 is a capable air-cooled, dual-slot card that performs best when paired with a CPU that can keep up at lower resolutions.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor based on the Comet Lake architecture, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. It has 12 MB of shared L3 cache and supports dual-channel DDR4 memory with a bandwidth of 42.7 GB/s. The CPU’s benchmark scores show a strong single-thread performance, with a Cinebench R23 single-core score of 1453 and a Passmark single-thread score of 2541. This single-thread strength is critical for Valorant, which is known to be sensitive to CPU frequency and per-core performance.

The CPU’s role is most evident at 1080p, where the frame rates are consistently high across all settings. At 1080p Low, the system hits 388.3 FPS, which is the highest recorded result in the entire dataset. The fact that lowering settings from High to Low only increases the average FPS by 62.1 FPS at 1080p suggests that the CPU is already near its limit for generating frames, and the GPU has enough headroom to render them quickly. The i5-10400F’s 6 cores and 12 threads are more than adequate for Valorant’s threading model, which typically uses fewer than 4 threads for gameplay logic.

The CPU’s bottleneck becomes more apparent when comparing 1440p results. At 1440p Low, the system achieves 365 FPS, which is only 23.3 FPS lower than the 1080p Low result. This small drop indicates that the CPU is still the primary limiter at 1440p Low, as the increased resolution does not significantly impact the CPU’s workload. However, at 1440p Ultra, the average FPS falls to 277.9, which is 87.1 FPS lower than 1440p Low. This shows that while the CPU sets the ceiling, the GPU’s rendering load at higher presets starts to pull the frame rate down. The i5-10400F’s 3DMark scores, including a 4-thread score of 2560 and an 8-thread score of 3929, reinforce that it has sufficient multi-threaded capability for this game, but the single-thread performance is what really matters here.

Settings Recommendations

The measured data suggests that the best experience for most players is the Medium preset at 1440p, as it balances visual quality with a high frame rate. At 2560x1440 Medium, the system averages 305.7 FPS, which is only 59.3 FPS lower than the 1080p Low result of 388.3 FPS, while providing noticeably better visuals. Compared to 1440p High (292.4 FPS), Medium is 13.3 FPS faster, and it is 27.8 FPS faster than 1440p Ultra (277.9 FPS). The gap between Medium and High at 1440p is relatively small, but the extra frame rate headroom can be valuable for maintaining consistent performance in competitive scenarios.

For players who prioritize maximum frame rate over visual fidelity, the Low preset at 1080p is the clear choice. At 1920x1080 Low, the system achieves 388.3 FPS, which is 61.1 FPS higher than the 1080p High result of 326.2 FPS. This setting is ideal for high-refresh-rate monitors, as it provides the most headroom above the 240 Hz refresh rate that many competitive players target. The difference between Low and Medium at 1080p is 60.5 FPS, so Low is worth considering if you are chasing every frame.

At 4K, the Medium preset is the most sensible option. The 3840x2160 Medium result of 245.3 FPS is 14.6 FPS higher than High (230.7 FPS) and 21.2 FPS higher than Ultra (224.1 FPS). While 4K Low is faster at 341.2 FPS, the visual compromise is significant, and the 4K Medium result still provides a smooth experience on most high-refresh-rate 4K displays. The data shows that Ultra settings at 4K are the least efficient, offering only a marginal visual improvement over High while costing 6.6 FPS, so it is best avoided unless you have a monitor that supports the frame rate.
