Valorant

The AMD Ryzen 9 8945HX paired with the NVIDIA GeForce RTX 5090 is a top-tier mobile combination, and in Valorant, the data shows a system that is entirely unburdened by the CPU or GPU at any resolution. The measured frame rates are exceptionally high across the board, with the lowest average being 417 FPS at 4K Ultra. This places the combo in the 462nd rank out of 2,883 tested combinations, firmly in the top percentile for this title. The benchmark results indicate that this is a system built for maximum refresh rates, where the primary differentiator between settings is not playability, but sheer headroom.

Resolution Scaling

The frame rate deltas across resolutions are remarkably tight, which is a strong indicator that Valorant is not a demanding title for this hardware. At High settings, the average FPS moves from 497 at 1920x1080, to 471 at 2560x1440, and finally to 438 at 3840x2160. This represents a drop of 26 FPS (5.2%) from 1080p to 1440p, and a further drop of 33 FPS (7.0%) from 1440p to 4K. The total scaling penalty from 1080p to 4K is just 59 FPS, or roughly 11.9% of the 1080p performance.

This minimal scaling behavior suggests that the system is heavily bound by the game's engine or CPU single-thread performance, rather than the GPU. The RTX 5090, with its massive 32 GB of GDDR7 memory on a 512-bit bus, has a bandwidth of 1.79 TB/s, which is far more than any current game needs for frame buffer access. The data shows that even at 4K, the GPU is not struggling to fill pixels; the pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are more than sufficient. The difference between 1080p and 4K is only a 12% reduction in FPS, which is typical for a game that is not GPU-bound at these settings.

The trend is consistent across all settings presets. For Low settings, the drop is slightly steeper in percentage terms, going from 593 FPS at 1080p to 522 FPS at 4K, a 71 FPS or 12% reduction. This is because at lower settings, the CPU has to handle a higher frame rate, and the slight increase in CPU load at higher resolutions becomes more apparent. Conversely, at Ultra settings, the difference is a mere 72 FPS (489 to 417), showing that the GPU is still not the limiting factor. The conclusion is clear: this processor and graphics card combination has enough raw power to keep Valorant's frame rate pinned to CPU limits, regardless of the resolution you choose.

Settings Recommendations

The measured data provides a clear hierarchy of performance across the four presets. At every resolution, Low settings yield the highest average frame rate, followed by Medium, then High, with Ultra being the slowest. However, the differences are so small that they are almost negligible in real-world terms. At 1920x1080, the spread is from 593 FPS on Low to 489 FPS on Ultra, a gap of 104 FPS. At 4K, the spread narrows to 522 FPS (Low) versus 417 FPS (Ultra), a 105 FPS difference.

For players with high-refresh-rate monitors, the best experience is arguably at Medium settings. The data shows that at 1080p Medium, the average FPS is 505, with a minimum of 430 and a maximum of 581. This is only 88 FPS slower than Low, but it comes with the visual improvements of Medium. The same pattern holds at 1440p (479 average) and 4K (445 average). The 1% low values for Medium are also solid, indicating consistent frame pacing. High settings offer a slight visual upgrade over Medium but cost about 26 FPS on average at 1080p (497 vs 505) and just 7 FPS at 4K (438 vs 445). Ultra is the most demanding, but it still delivers an average of 417 FPS at 4K, which is far above the refresh rate of any current monitor.

Given the data, the recommendation is to select Medium as the baseline for the best balance, as it provides a significant FPS boost over High and Ultra while maintaining a smooth experience. For those seeking the absolute maximum frame rate, Low is the only choice, but the difference is small. Since the minimum FPS for Ultra is not listed, the data suggests that Medium is the safest choice for a locked, high-refresh experience, with the measured 430 FPS minimum at 1080p ensuring no drops below 360Hz displays.

GPU Role

The NVIDIA GeForce RTX 5090 is a behemoth of a graphics card, built on the Blackwell 2.0 architecture with a 5 nm process node from TSMC. It features 21,760 shading units and 176 ROPs, with a boost clock of 2407 MHz. In Valorant, however, these specifications are largely irrelevant, as the game's engine—designed for competitive play—places minimal load on the GPU. The data confirms this: the GPU's role here is to render frames at a rate that the CPU can feed it, and it does so without breaking a sweat.

The GPU's 32 GB of GDDR7 memory is a massive amount of VRAM, but Valorant does not use it. The game's textures and geometry are simple, so memory capacity is not a bottleneck. The memory bandwidth of 1.79 TB/s is similarly overprovisioned. The benchmark results show that the GPU is not the limiting factor at any resolution or setting, as evidenced by the small FPS deltas between 1080p and 4K. If the GPU were the bottleneck, we would expect to see a much steeper drop in performance as resolution increases, which is not the case.

The RTX 5090's average benchmark score is 79,842, putting it in the 92nd percentile of all GPUs. Its nearest rivals include the NVIDIA Tesla P100 PCIe 16 GB, which is 0.3% slower, and the AMD Radeon RX 6850M XT, which is 1.1% slower. In Valorant, this performance ranking means nothing, as the GPU is effectively idling. The data suggests that a much less powerful GPU would yield nearly identical frame rates, as the system is held back by the CPU's single-thread performance and the game engine's frame rate limit. The GPU's high FP32 throughput of 104.8 TFLOPS is wasted on a game that relies more on draw calls than raw shader processing.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all combinations of resolution and settings.

At 1920x1080, the lowest resolution tested, the system is clearly CPU-bound. The Low preset delivers an average of 593 FPS, which is the highest score in the entire dataset. The Medium preset averages 505 FPS, with a minimum of 430 FPS and a maximum of 581 FPS. The High preset averages 497 FPS, and the Ultra preset averages 489 FPS. The spread between Low and Ultra is 104 FPS, but all values are exceptionally high.

Moving to 2560x1440, the results show a slight decrease. Low settings average 562 FPS, a 31 FPS drop from 1080p. Medium settings average 479 FPS, with a minimum of 407 FPS and a maximum of 551 FPS. High settings average 471 FPS, and Ultra settings average 464 FPS. The scaling penalty is minimal, with the difference between 1080p and 1440p at Low settings being just 5.2%.

At 3840x2160, the resolution is still not a challenge. Low settings average 522 FPS, Medium averages 445 FPS (min 378 FPS, max 512 FPS), High averages 438 FPS, and Ultra averages 417 FPS. The data shows that even at 4K Ultra, the system maintains an average above 400 FPS, which is more than any monitor can display. The minimum FPS recorded at 4K Medium is 378, which is still far above the 240Hz threshold. The overall pattern is a system that is so fast that the only way to see a performance drop is to increase the resolution, but even that has a negligible effect.

CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor based on the Zen 4 architecture, codenamed Dragon Range. It has a base clock of 2.50 GHz and a boost clock of 5.40 GHz, with a 64 MB L3 cache. In Valorant, the CPU is the primary component dictating performance. The data shows that frame rates are consistently high, but the scaling across resolutions is flat, which is a classic sign of a CPU bottleneck. The game's engine is not heavily multithreaded, so the 16 cores and 32 threads are not all utilized; instead, the game relies on the high single-thread performance and the 5.40 GHz boost clock.

The CPU's benchmark scores reflect its strength. Its Cinebench R23 multi-core score is 42,713, and the single-core score is 6,030. The PassMark single-thread score is 3,907. These numbers indicate a top-tier mobile processor. The nearest rivals in the CPU benchmark database are the Intel Core Ultra 9 285HX (0.1% faster), the AMD Ryzen 9 9950X3D (0.6% slower), and the AMD EPYC Embedded 8224P (0.4% slower). For Valorant, the single-thread performance is what matters most, and the data shows that the Ryzen 9 8945HX is strong enough to push frame rates past 500 FPS at 1080p.

The CPU's large 64 MB L3 cache is also beneficial, as it can store the game's frequently accessed data, reducing memory latency. The data shows that the CPU is the limiting factor in this title; no matter how low the resolution or settings are, the frame rate ceiling is around 593 FPS at 1080p Low. This is a hardware limit imposed by the CPU's ability to process the game's draw calls and game logic, not by the GPU. The fact that the system ranks 462nd out of 2,883 combinations suggests that there are a few other processors that can push even higher frame rates, but the difference is marginal. The CPU's 95th percentile ranking in the overall database confirms that it is one of the fastest mobile chips available, and its performance in Valorant is limited by the game's own engine, not by the silicon.
