CPU Role

The AMD Ryzen 9 8945HX is a 16-core, 32-thread processor from the 8000 series, built on TSMC's 5 nm process with the Zen 4 architecture under the Dragon Range codename. It operates with a base clock of 2.50 GHz and a boost clock of 5.40 GHz, which provides substantial single-thread headroom for action games like Overpower that often rely on a few primary threads for game logic and physics. The processor's 64 MB of L3 cache and 1 MB of L2 cache per core help keep frequently accessed data close to the execution units, reducing memory latency in CPU-bound scenes.

The CPU's benchmark results demonstrate its capability in multi-threaded workloads. In Cinebench R23, it scores 42713 in multicore and 6030 in single-core tests. The Passmark multithread score reaches 51405, while single-thread performance sits at 3907. These numbers indicate a processor that can handle both heavily threaded rendering tasks and the lighter single-threaded demands of game simulation. The CPU's 95th percentile ranking versus all CPUs confirms that it sits near the top of the performance spectrum.

For Overpower specifically, the CPU's role becomes more pronounced at lower resolutions. At 1080p with Low settings, the combo achieves 222 FPS, which is substantially higher than the 168 FPS seen at 4K Low. This pattern suggests that at 1080p, the CPU has enough headroom to feed the GPU with frames, while at 4K, the GPU becomes the primary limiter. The CPU's 16 cores and 32 threads also provide ample parallelism for background tasks, streaming, and any auxiliary processes running alongside the game.

The processor's memory bandwidth of 83.2 GB/s over dual-channel DDR5 is adequate for feeding 16 cores, and the PCIe Gen 5 interface with 28 lanes ensures the GPU has a high-bandwidth connection for texture streaming. The integrated Radeon 610M graphics are present but not relevant for gaming performance when a discrete RTX 5090 Mobile is installed.

GPU Role

The NVIDIA GeForce RTX 5090 Mobile is built on the Blackwell 2.0 architecture with the GB203 chip on a 5 nm TSMC process. It packs 10496 shading units, 328 texture mapping units, and 112 raster output units, along with 82 ray tracing cores and 328 tensor cores. The GPU operates with a base clock of 990 MHz and a boost clock of 1515 MHz, while the 24 GB of GDDR7 memory runs at 1750 MHz (28 Gbps effective) across a 256-bit bus, delivering 896.0 GB/s of memory bandwidth.

The GPU's compute capabilities are substantial, with 31.80 TFLOPS of FP32 performance and an equal 31.80 TFLOPS for FP16. The pixel rate reaches 169.7 GPixel/s and texture rate hits 496.9 GTexel/s. These specifications translate to strong raw throughput for filling pixels and applying textures, which directly impacts Overpower's visual fidelity at high resolutions and detail settings.

In benchmark tests, the RTX 5090 Mobile scores 30034 in Passmark G3D and 13401 in GPU compute, with a 3DMark Steel Nomad DX12 score of 5871. The Geekbench OpenCL score of 201834 and Vulkan score of 198405 further demonstrate the GPU's compute and rendering prowess. The 84th percentile ranking versus all GPUs places it well above average, though not at the very top tier.

For Overpower, the GPU's 24 GB VRAM capacity is particularly relevant at 4K resolution with High or Ultra settings, where large texture sets and high-resolution assets consume significant memory. The 896.0 GB/s memory bandwidth ensures that the GPU can quickly access these textures without becoming a bottleneck. The difference between Low and Ultra settings at 4K is stark — 168 FPS versus 81 FPS — indicating that the GPU is the dominant factor in scaling visual quality.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 222 FPS, Medium settings reach 139 FPS with a minimum of 118 and maximum of 160, High settings hit 129 FPS, and Ultra settings drop to 107 FPS. The gap between Low and Ultra at this resolution is 115 FPS, showing that the GPU has significant headroom at 1080p.

Moving to 2560x1440, the frame rates scale down proportionally. Low settings average 198 FPS, Medium settings average 124 FPS with a range of 105 to 142, High settings reach 115 FPS, and Ultra settings settle at 95 FPS. The difference between Low and Ultra here is 103 FPS, slightly less than at 1080p, indicating that resolution scaling is beginning to pressure the GPU.

At 3840x2160, the performance envelope tightens considerably. Low settings average 168 FPS, Medium settings average 105 FPS with a minimum of 90 and maximum of 121, High settings achieve 98 FPS, and Ultra settings drop to 81 FPS. The spread between Low and Ultra at 4K is 87 FPS, the smallest of the three resolutions. This narrowing suggests that at 4K, even the RTX 5090 Mobile begins to approach its limits, and the CPU's role diminishes relative to the GPU.

Across all resolutions, the Medium settings consistently show a wider FPS range (minimum to maximum) compared to other settings, which have null min/max values. For instance, at 1080p Medium, the range is 118 to 160 FPS, while at 4K Medium, it is 90 to 121 FPS. This variance may indicate that Medium settings produce more frame time variability in Overpower.

Resolution Scaling

The FPS drop from 1080p to 4K reveals how the workload shifts between CPU and GPU. At Low settings, the average FPS goes from 222 at 1080p to 198 at 1440p and 168 at 4K. This represents a 24.3% reduction from 1080p to 4K. At High settings, the progression is 129 to 115 to 98 FPS, a 24.0% reduction. Ultra settings go from 107 to 95 to 81 FPS, a 24.3% reduction. The consistency of these percentages across settings indicates that resolution scaling is uniform regardless of visual quality.

The fact that the percentage drop is nearly identical across Low, High, and Ultra settings suggests that the limiting component does not change with settings. If the CPU were the bottleneck at low settings, we would expect a smaller percentage drop when increasing resolution, because the GPU would have more headroom to work. Instead, the steady 24% reduction implies that the GPU is the primary limiter at all settings, even at 1080p Low where 222 FPS is achieved.

However, the absolute FPS at 1080p Low (222) is high enough that the CPU must be capable of feeding the GPU at that rate. The Ryzen 9 8945HX's boost clock of 5.40 GHz and strong single-thread performance (6030 in Cinebench R23 single-core) provide the necessary throughput. At 4K Ultra, the 81 FPS figure indicates that the GPU's fill rate and shading capacity are the constraints, not the CPU.

The Medium settings data points, which include min and max FPS values, offer additional insight. At 1080p Medium, the range is 118 to 160 FPS, a 42 FPS spread. At 1440p Medium, the range is 105 to 142, a 37 FPS spread. At 4K Medium, the range is 90 to 121, a 31 FPS spread. The narrowing range at higher resolutions suggests that frame pacing becomes more consistent as the GPU becomes more uniformly loaded.

Settings Recommendations

Based on the measured FPS values, the optimal settings depend on the target refresh rate and resolution. At 1080p, all settings exceed 100 FPS, with Ultra still delivering 107 FPS. For players with 144 Hz displays, High settings at 129 FPS or Medium at 139 FPS both provide smooth gameplay, while Ultra at 107 FPS may be preferable for those prioritizing visual quality over raw frame rate.

At 1440p, the choice becomes more nuanced. Ultra settings at 95 FPS remain playable, but High at 115 FPS offers a better balance for high-refresh displays. Medium at 124 FPS is the highest average at this resolution, though the 105 to 142 FPS range suggests some variability. For competitive play, Low at 198 FPS provides maximum responsiveness.

At 4K, the situation changes dramatically. Ultra settings at 81 FPS are playable for cinematic experiences but may not satisfy players with 120 Hz or 144 Hz displays. High settings at 98 FPS offer a better compromise, while Medium at 105 FPS with a minimum of 90 FPS provides the best balance of visual fidelity and performance for most 4K displays. Low at 168 FPS is available for players who prioritize frame rate above all else.

The data suggests that Medium settings provide the best overall experience at each resolution, as they offer the highest average FPS among the quality-oriented presets (excluding Low) while maintaining acceptable visual quality. At 1080p Medium, 139 FPS is only 10 FPS below High but offers a noticeable improvement over Ultra. At 1440p Medium, 124 FPS is 9 FPS above High. At 4K Medium, 105 FPS is 7 FPS above High and 24 FPS above Ultra.
