Overpower

# Overpower — AMD Ryzen 9 8945HX + NVIDIA GeForce RTX 4090

The AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 4090 combination delivers a stratified performance profile in Overpower, where frame rates scale predictably with resolution and settings, but the gaps between presets reveal a system that is never truly bottlenecked at any tested configuration. With measured averages ranging from 78 FPS at 4K Ultra to 213 FPS at 1080p Low, this pairing demonstrates headroom that shifts depending on where the workload lands. The data shows a combo ranked 602nd out of 2,980 tested combinations, placing it comfortably in the top 20% of all systems evaluated for this title.

Resolution Scaling

The transition from 1080p to 4K produces a clear and consistent frame rate decline across every settings preset, but the magnitude of that drop varies significantly depending on the quality level. At Low settings, the average FPS falls from 213 at 1920x1080 to 190 at 2560x1440, then to 161 at 3840x2160 — a total reduction of 52 FPS, or roughly 24% from the 1080p baseline. This relatively modest scaling suggests that at Low settings, the CPU and GPU are both operating with enough headroom that even a 4x increase in pixel count (from 1080p to 4K) cannot fully saturate the pipeline.

Medium settings tell a different story. The average drops from 133 FPS at 1080p to 118 FPS at 1440p, then to 101 FPS at 4K. The 32 FPS gap between 1080p and 4K represents a 24% reduction — nearly identical in percentage terms to the Low setting scaling. However, the absolute frame rates are lower across the board, indicating that the increased graphical workload at Medium is already engaging more of the GPU's resources before resolution scaling begins.

High settings exhibit the steepest relative decline. From 123 FPS at 1080p, the average falls to 110 FPS at 1440p and then to 93 FPS at 4K — a 30 FPS drop that equals a 24.4% reduction. Ultra settings, meanwhile, show a 102 FPS average at 1080p, 91 FPS at 1440p, and 78 FPS at 4K, for a 23.5% decline. The consistency of these percentage drops — all hovering between 23% and 24.5% — suggests that resolution scaling in Overpower follows a predictable curve for this hardware, with no single resolution or setting combination causing an anomalous cliff.

What the data implies is that the limiting component shifts subtly across the resolution spectrum. At 1080p, the relatively narrow gaps between Low (213 FPS) and Ultra (102 FPS) — a 111 FPS spread — indicate that the CPU is capable of feeding the GPU at high rates, but the GPU's workload at Ultra brings it closer to its performance ceiling. At 4K, the spread narrows to 83 FPS (161 Low vs. 78 Ultra), suggesting that the GPU becomes more dominant as the pixel count increases, compressing the performance envelope.

GPU Role

The NVIDIA GeForce RTX 4090 in this configuration carries 24 GB of GDDR6X memory across a 384-bit bus, yielding 1.01 TB/s of bandwidth. In Overpower, these specifications provide ample headroom for texture streaming and asset loading at all tested settings, as evidenced by the fact that even at 4K Ultra, the system maintains a 78 FPS average without dipping below playable thresholds (min FPS data is only recorded for Medium settings, where 86 FPS at 4K represents the lowest single-moment figure in the entire dataset).

The GPU's clock behavior — a 2235 MHz base and 2520 MHz boost — contributes to the observed scaling. The boost clock is likely sustained during the lighter 1080p and 1440p workloads, allowing the card to deliver 213 FPS at Low 1080p. At 4K Ultra, the sustained load likely prevents the boost clock from holding maximum frequency, which partially explains the 78 FPS result. The 88th percentile ranking among all GPUs places this card in the upper tier, though the nearest rivals — Intel Arc Pro A60 (0% delta), AMD Radeon Pro Vega 48 (0.3% delta), and AMD Radeon PRO V710 (2.9% delta) — are not consumer gaming parts, which contextualizes the RTX 4090's position relative to its actual competition.

The 5 nm process node and Ada Lovelace architecture with 16,384 shading units provide the raw compute necessary for Overpower's effects. The 82.58 TFLOPS FP32 throughput is likely leveraged during particle-heavy action sequences, while the 128 RT cores handle any ray-traced elements the game may present — though the measured data does not isolate RT performance specifically. The 24 GB VRAM capacity exceeds what Overpower likely requires even at 4K Ultra, meaning memory capacity is not a limiting factor in any measured configuration.

FAQ

Q: Why does the FPS drop from 213 at 1080p Low to 161 at 4K Low, but the percentage drop is similar to other settings?

A: The data shows a 24.4% reduction across that range, nearly identical to the 23.5% drop at Ultra settings. This consistency indicates that resolution scaling in Overpower affects all quality presets proportionally, suggesting the GPU workload increases linearly with pixel count regardless of the settings level.

Q: Is the RTX 4090's 24 GB VRAM necessary for Overpower?

A: The measured results do not indicate any VRAM-related performance cliffs. Even at 4K Ultra, the average FPS of 78 with no recorded minimum below 86 (at Medium 4K) suggests that memory capacity is not a bottleneck. The 1.01 TB/s bandwidth provides sufficient throughput for all tested configurations.

Q: What does the combo rank of 602 out of 2,980 mean for real-world performance?

A: This places the system in the top 20.2% of all tested combinations for Overpower. Given that this rank includes desktop and workstation configurations, the mobile-oriented Ryzen 9 8945HX paired with the RTX 4090 delivers competitive performance against a broad field.

Q: How does the CPU's benchmark performance relate to its gaming results here?

A: The Ryzen 9 8945HX scores 42,713 in Cinebench R23 multi-core and 6,030 in single-core, placing it at the 95th percentile among all CPUs. In Overpower, the 1080p Low result of 213 FPS — the highest measured — indicates the CPU can feed the GPU at high frame rates without becoming a limiting factor.

Q: Why is the FPS gap between Low and Ultra wider at 1080p (111 FPS) than at 4K (83 FPS)?

A: At 1080p, the GPU has spare capacity, so increasing settings from Low to Ultra adds workload that the GPU can partially absorb, resulting in a larger FPS spread. At 4K, the GPU is already heavily loaded at Low settings, so the incremental cost of Ultra settings compresses the range.

Q: Does the RTX 4090's 88th percentile GPU ranking reflect its Overpower performance?

A: The percentile is based on synthetic benchmarks (Passmark G3D score of 38,194), not Overpower-specific tests. The measured FPS data in this game — 78 FPS at 4K Ultra — provides a more direct indication of real-world capability, though the two metrics align in showing a high-performing part.

How This Combo Ranks

The combination of AMD Ryzen 9 8945HX and NVIDIA GeForce RTX 4090 holds the 602nd position out of 2,980 tested combos in Overpower, placing it in the 79.8th percentile of all systems evaluated. This rank reflects the pairing's ability to deliver high frame rates across all tested configurations, but it also suggests that other combinations — likely those with newer or more specialized components — achieve higher scores in this specific title.

Examining the CPU's nearest rivals provides context: the Intel Core Ultra 9 285HX scores within 0.1% of the Ryzen 9 8945HX in average benchmark score, while the AMD Ryzen 9 9950X3D trails by 0.6%. These deltas are minimal, indicating that the CPU choice has negligible impact on the combo's overall ranking when paired with the same GPU. The GPU's nearest rivals show similarly small deltas (0% to 2.9%), but these are professional and workstation cards, not gaming-focused parts, which means the RTX 4090's true competition in gaming scenarios is not represented in the nearestRivals list.

The rank of 602 suggests that while this combo is strong, it is not the absolute top-tier performer for Overpower. The 2,980 total combos include a wide range of hardware, and the 602nd position indicates that roughly 600 other combinations deliver better measured results. Given that this is a mobile CPU (55 W TDP) paired with a desktop-class GPU (450 W TDP), the thermal and power constraints of the platform may contribute to the ranking — the CPU's 5.40 GHz boost clock is impressive for a 55 W part, but sustained gaming loads may not always reach that ceiling.

CPU Role

The AMD Ryzen 9 8945HX brings 16 cores and 32 threads based on the Zen 4 architecture, with a 2.50 GHz base clock and 5.40 GHz boost clock. This Dragon Range processor, built on a 5 nm TSMC process with 13,140 million transistors across two 71 mm² dies, delivers benchmark scores that place it at the 95th percentile of all CPUs. The Cinebench R23 multi-core score of 42,713 and single-core score of 6,030 indicate strong performance in both threaded and lightly-threaded workloads.

In Overpower, the CPU's role is most evident at lower resolutions and settings where the GPU is less stressed. The 213 FPS average at 1080p Low is the highest measured figure in the dataset, and achieving that frame rate requires the CPU to process game logic, physics, and draw calls at a rate exceeding 200 per second. The 16-core configuration with 64 MB of L3 cache provides substantial headroom for these tasks, and the 83.2 GB/s memory bandwidth via DDR5 dual-channel support ensures data can flow to the cores without stalling.

The CPU's benchmark performance relative to its nearest rivals — including the Intel Core Ultra 9 285HX (0.1% delta) and AMD Ryzen 9 9950X3D (0.6% delta) — suggests that the processor is not a differentiator in this combo's ranking. All four nearest rivals fall within 1% of the Ryzen 9 8945HX's average benchmark score, indicating that Overpower's performance is more strongly influenced by the GPU. At 4K Ultra, where the GPU is the clear bottleneck, the CPU's contribution to frame pacing is likely minimal — the 78 FPS average is well below what the CPU can sustain.

The Passmark single-thread score of 3,907 and multi-thread score of 51,405 further reinforce that this processor can handle both the single-threaded game logic and any background tasks without compromising gaming performance. The 95th percentile ranking means this CPU outperforms 95% of all processors in general benchmarks, which aligns with its ability to support the GPU at 1080p without creating a bottleneck.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce a 213 FPS average, Medium achieves 133 FPS with a minimum of 113 and maximum of 153, High reaches 123 FPS, and Ultra settles at 102 FPS. The spread from Low to Ultra is 111 FPS, with the difference between Medium and High being just 10 FPS — a notably small gap that suggests Medium and High presets impose similar GPU workloads at this resolution.

Moving to 2560x1440, the averages decline across the board: Low yields 190 FPS, Medium 118 FPS (min 101, max 136), High 110 FPS, and Ultra 91 FPS. The gap between Medium and High narrows to 8 FPS, while the Low-to-Ultra spread compresses to 99 FPS. The 4K results at 3840x2160 show the lowest absolute performance: Low averages 161 FPS, Medium 101 FPS (min 86, max 116), High 93 FPS, and Ultra 78 FPS. The Medium-to-High gap shrinks further to 8 FPS, and the Low-to-Ultra spread is 83 FPS.

The Medium settings rows include minimum and maximum FPS data, which provides insight into frame time consistency. At 1080p Medium, the range from 113 to 153 FPS (a 40 FPS spread around the 133 average) indicates some frame time variance. At 1440p Medium, the range narrows to 101-136 FPS (35 FPS spread), while at 4K Medium, it tightens to 86-116 FPS (30 FPS spread). This pattern suggests that as resolution increases and the GPU becomes more saturated, frame times become more consistent — likely because the CPU has more time between frames to prepare the next one.

Settings Recommendations

For players prioritizing maximum frame rate, Low settings at 1080p deliver 213 FPS, which is more than double the 4K Ultra result. This configuration is ideal for competitive play where high refresh rates matter, though the visual fidelity trade-off is substantial. The jump from Low to Medium at 1080p costs 80 FPS (from 213 to 133), which is a significant sacrifice for the visual improvements Medium likely provides.

The Medium preset across all resolutions offers the most balanced experience, with the only complete min/max data in the dataset. At 1080p Medium, the 133 FPS average with a 113 FPS minimum remains comfortably above the 100 FPS threshold for smooth gameplay. At 1440p Medium, 118 FPS average with 101 minimum still provides excellent smoothness. Even at 4K Medium, the 101 FPS average with 86 FPS minimum keeps the experience playable on high-refresh displays, though the minimum dips closer to 60 FPS territory.

High settings offer marginal gains over Medium — just 10 FPS at 1080p, 8 FPS at 1440p, and 8 FPS at 4K — which suggests that the visual difference between Medium and High may not justify the frame rate cost. Ultra settings, conversely, impose a more substantial penalty: 31 FPS below High at 1080p, 19 FPS below at 1440p, and 15 FPS below at 4K. The diminishing returns from High to Ultra are more pronounced, making Ultra the least efficient preset for the frame rate it provides.

The optimal recommendation based on the measured data is Medium at 1080p or 1440p, depending on display resolution. Medium at 1440p delivers 118 FPS with a 101 FPS minimum, which balances visual quality and performance for most gaming scenarios. For 4K displays, Medium at 101 FPS average is the highest-quality setting that remains above 100 FPS, while High at 93 FPS may be acceptable for those prioritizing visuals over the 100 FPS threshold. Ultra settings are only advisable for players with 4K displays who prioritize absolute visual fidelity over frame rate, accepting the 78 FPS average.
