Overpower

Overpower, an action title released in August 2023, exhibits a clear GPU-bound scaling pattern on this AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5090 combo. The frame rate drops from 222 FPS at 1080p Low to just 81 FPS at 4K Ultra, a 64% reduction that underscores the extreme demands of 4K rendering. The data indicates that the RTX 5090 remains the limiting factor even at lower resolutions, as the CPU's 16-core Zen 4 architecture provides ample headroom.

Resolution Scaling

The measured FPS data reveals a predictable but steep decline as resolution increases. At the Low preset, the combo delivers 222 FPS at 1920x1080, 198 FPS at 2560x1440, and 168 FPS at 3840x2160. This represents a 24% drop from 1080p to 1440p, and a further 15% drop from 1440p to 4K. The scaling is nearly linear with pixel count, which is the classic signature of a GPU-bound workload. The CPU is not the bottleneck here; the Ryzen 9 8945HX with its 16 cores and 32 threads is more than capable of feeding the GPU at these frame rates.

For the High preset, the pattern holds: 129 FPS at 1080p, 115 FPS at 1440p, and 98 FPS at 4K. The percentage drops are 11% and 15% respectively, showing that the High preset is slightly less demanding than Low, allowing the GPU to maintain higher utilization across resolutions. The Medium preset shows a similar trend, with 139 FPS at 1080p, 124 FPS at 1440p, and 105 FPS at 4K. Notably, the Medium preset at 4K (105 FPS) is faster than the High preset at 1440p (115 FPS), suggesting that the preset's impact on GPU load is more significant than the resolution change in this mid-range.

The Ultra preset is the most demanding, yielding 107 FPS at 1080p, 95 FPS at 1440p, and 81 FPS at 4K. The gap between 1080p and 4K at Ultra is 26 FPS, or 24%, which is smaller in absolute terms than the 54 FPS gap at Low. This indicates that at Ultra settings, the GPU is working closer to its maximum capacity even at 1080p, so the resolution scaling effect is somewhat muted. Overall, the data suggests that this combo is optimized for high-refresh 1440p gaming, where it can exceed 100 FPS on most presets, while 4K gaming is viable but requires dropping to Medium or High to maintain smooth frame rates.

How This Combo Ranks

In the Overpower benchmark database, this combination of AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 5090 ranks 561st out of 2980 tested combos. This places it in the top 19% of all configurations, which is a strong showing for a mobile platform. The percentile data for the individual components reinforces this: the CPU sits in the 95th percentile against all CPUs, while the GPU is in the 92nd percentile against all GPUs. This combination of two top-tier parts yields a system that is comfortably above average for this game.

The CPU's nearest rivals provide context for its performance. The Intel Core Ultra 9 285HX has an average score of 76155, which is a 0.1% delta from the Ryzen 9 8945HX's 76212. This is essentially a statistical tie, meaning the two processors are interchangeable in terms of raw compute for this title. The AMD EPYC Embedded 8224P (76492) and AMD Ryzen Threadripper PRO 9945WX (76513) are 0.4% ahead, while the AMD Ryzen 9 9950X3D (75779) is 0.6% behind. All four rivals are within 1% of the 8945HX, indicating that CPU choice has minimal impact on Overpower's frame rates when paired with a high-end GPU.

The GPU's nearest rivals show a different picture. The NVIDIA Tesla P100 PCIe 16 GB has an average score of 79605, a 0.3% delta from the RTX 5090's 79842. The Tesla P100 PCIe 12 GB (79396) is 0.6% behind, and the AMD Radeon RX 6850M XT (78940) is 1.1% behind. However, the AMD Radeon Pro Vega 64X (80959) is 1.4% ahead, which is a notable margin in the benchmark database. This suggests that while the RTX 5090 is a top-tier gaming GPU, its raw compute score is not the absolute highest in every metric, and some workstation-oriented parts can exceed it in synthetic tests.

GPU Role

The NVIDIA GeForce RTX 5090 is the primary driver of Overpower's performance, as evidenced by the resolution scaling data. Its 32 GB of GDDR7 memory on a 512-bit bus provides a massive 1.79 TB/s of bandwidth, which is more than sufficient for the game's textures and geometry at all tested settings. The memory clock is listed at 1750 MHz with 28 Gbps effective speed, and the base clock is 2017 MHz with a boost clock of 2407 MHz. These clocks are high for a laptop GPU, and the boost behavior ensures sustained performance during extended gaming sessions.

The GPU's architecture, Blackwell 2.0, includes 21760 shading units, 680 TMUs, and 176 ROPs. This configuration yields a pixel rate of 423.6 GPixel/s and a texture rate of 1636.8 GTexel/s, which are the key metrics for rasterization performance. The FP32 throughput of 104.8 TFLOPS indicates the raw compute available for shader work, and the 170 RT cores provide hardware acceleration for ray tracing effects, though the measured FPS data does not specify whether ray tracing was enabled. The 680 tensor cores are present for DLSS and other AI features, but the benchmark results are based on native rendering.

The RTX 5090's TDP is 575 W, which is substantial for a mobile platform, and it requires a 950 W suggested power supply. This power draw is a trade-off for the high performance, but the data shows it delivers. The GPU's 92nd percentile ranking against all GPUs confirms its position as one of the fastest available, and the measured frame rates in Overpower reflect this. The 3DMark Steel Nomad DX12 score of 18355 and the Geekbench Vulkan score of 376728 further corroborate the GPU's strength in modern rendering workloads.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings presets. At 1920x1080, the Low preset delivers an average of 222 FPS, which is the highest recorded. The Medium preset achieves 139 FPS with a min of 118 FPS and a max of 160 FPS, while the High preset yields 129 FPS. The Ultra preset drops to 107 FPS. This shows a clear hierarchy: Low > Medium > High > Ultra, with a 115 FPS difference between the most and least demanding settings at 1080p.

At 2560x1440, the Low preset averages 198 FPS, a 24 FPS decrease from 1080p. The Medium preset averages 124 FPS with a min of 105 FPS and a max of 142 FPS, which is a 15 FPS drop. The High preset delivers 115 FPS, and the Ultra preset averages 95 FPS. The scaling from 1080p to 1440p is consistent across all presets, with an average drop of about 12%. This indicates that the GPU is the primary limiter, as the additional pixel count directly impacts frame rate.

At 3840x2160, the Low preset still manages 168 FPS, which is impressive for 4K. The Medium preset averages 105 FPS with a min of 90 FPS and a max of 121 FPS, making it the most balanced option for 4K gaming. The High preset averages 98 FPS, and the Ultra preset drops to 81 FPS. The difference between 1080p and 4K at Low is 54 FPS (24%), while at Ultra it is 26 FPS (24%). This consistency suggests that the GPU's performance scales linearly with pixel count, regardless of the settings preset.

Settings Recommendations

Based on the measured data, the optimal settings depend on the target refresh rate and resolution. For 4K gaming, the Medium preset is the recommended choice, as it delivers 105 FPS with a minimum of 90 FPS. This ensures smooth gameplay without dipping below 90 FPS, which is a common threshold for high-refresh displays. The High preset at 4K offers 98 FPS, which is also acceptable, but the Medium preset's higher minimum frame rate makes it more consistent. The Ultra preset at 4K should be avoided for competitive play, as the 81 FPS average may feel less responsive.

For 1440p, the High preset is the sweet spot, providing 115 FPS with a comfortable margin above the 100 FPS mark. The Medium preset at 1440p offers 124 FPS, which is slightly faster, but the visual quality difference may not be worth the 9 FPS gain. The Ultra preset at 1440p averages 95 FPS, which is playable but not ideal for high-refresh monitors. For 1080p gaming, the High preset at 129 FPS is recommended for a balance of quality and speed. The Medium preset at 139 FPS is also viable, but the Low preset at 222 FPS is excessive for most displays unless targeting 240 Hz or higher.

The data shows that this combo is best utilized at 1440p, where it can exceed 100 FPS on High settings, or at 4K with Medium settings. The Ultra preset is only recommended for 1080p, where it still delivers 107 FPS. For players prioritizing frame rate over visual fidelity, the Low preset at 1440p (198 FPS) or 4K (168 FPS) offers exceptional performance that exceeds the capabilities of most displays. The benchmark results indicate that the RTX 5090's 32 GB VRAM is never a limiting factor, even at 4K Ultra, as the frame rate is constrained by the GPU's compute and memory bandwidth rather than capacity.
