# Overpower with Intel Core Ultra 9 275HX + NVIDIA GeForce RTX 4090

The Intel Core Ultra 9 275HX paired with the NVIDIA GeForce RTX 4090 delivers a formidable mobile gaming combination, and the measured results in Overpower reveal a system that excels across all resolution tiers. This 24-core, 24-thread Arrow Lake-HX processor with a 5.40 GHz boost clock drives the RTX 4090 with 24 GB of GDDR6X memory and a 1.01 TB/s bandwidth, producing frame rates that range from a 213 FPS average at 1080p Low to a still-respectable 78 FPS at 4K Ultra. The data paints a picture of a laptop platform that can handle esports-level responsiveness and near-4K cinematic quality, though the scaling patterns between resolutions and settings offer intriguing insights into where the bottleneck truly lies.

Resolution Scaling

The measured FPS data shows a clear and consistent downward trend as resolution increases, but the magnitude of that drop varies significantly by settings preset. At Low settings, the average frame rate falls from 213 FPS at 1920x1080 to 190 FPS at 2560x1440—a modest 23 FPS reduction—and then to 161 FPS at 3840x2160, representing a total drop of 52 FPS from 1080p to 4K. This translates to a 24.4% performance loss at 4K relative to 1080p, which is surprisingly small given the 4x pixel count increase, suggesting the system is not purely GPU-limited at lower settings.

The story changes dramatically at Medium settings. Here, 1080p yields 133 FPS, 1440p drops to 118 FPS, and 4K reaches 101 FPS—a gentler absolute decline of 32 FPS from top to bottom, but with a 1080p-to-4K loss of 24.1%. The High preset shows a similar pattern: 123 FPS at 1080p, 110 FPS at 1440p, and 93 FPS at 4K, for a 30 FPS total drop. Ultra settings compress the range further, with 102 FPS at 1080p, 91 FPS at 1440p, and 78 FPS at 4K—a 24 FPS decline that represents a 23.5% loss at 4K.

What these numbers imply is that the RTX 4090, with its 82.58 TFLOPS FP32 throughput and 443.5 GPixel/s pixel rate, remains remarkably capable even as pixel count quadruples. The percentage losses across all presets cluster tightly between 23% and 25%, which indicates that the scaling penalty is relatively uniform regardless of settings. This uniformity suggests that the GPU's raw compute and memory bandwidth—1.01 TB/s—are sufficient to handle the increased resolution demand without a disproportionate frame rate collapse. The CPU, with its 24 cores and high boost clock, appears to keep feeding the GPU adequately even at 1080p where CPU overhead typically becomes more pronounced.

GPU Role

The RTX 4090's specifications read like a desktop-class component in a mobile chassis: 16,384 shading units, 512 tensor cores, 128 RT cores, and a boost clock of 2520 MHz. Its 24 GB of GDDR6X memory on a 384-bit bus delivers 1.01 TB/s of bandwidth, which is critical for high-resolution textures and the kind of dense action scenes Overpower likely presents. The data shows that this memory configuration prevents bandwidth starvation even at 4K, where the Medium preset still manages 101 FPS with a minimum of 86 FPS.

The GPU's benchmark scores reinforce its position. With an average benchmark score of 60,347 and a percentile ranking of 88 against all GPUs, it sits near the top of the field. Its nearest rivals in the database are the Intel Arc Pro A60 (deltaPct 0), AMD Radeon Pro Vega 48 (deltaPct 0.3), and AMD Radeon Pro W6600M (deltaPct -2.5), though these are workstation-oriented parts that trail in gaming-focused workloads. The 3DMark Steel Nomad DX12 score of 9,223 and Geekbench Vulkan score of 271,631 indicate strong API-level performance that translates well to modern game engines.

Interestingly, the GPU's end-of-life production status and launch MSRP of 1,599 USD suggest this is a top-tier part that has been superseded, yet its measured gaming performance remains exceptional. The 450 W TDP and 850 W suggested PSU hint at the power appetite required to sustain these frame rates, though in a laptop form factor, the thermal and power delivery constraints would be managed by the platform design. The data indicates that at 1080p Low, the GPU can push 213 FPS, which is well beyond typical 144 Hz display refresh rates, making the CPU the more likely limiting factor at lower resolutions.

CPU Role

The Intel Core Ultra 9 275HX brings substantial processing muscle to this pairing. With 24 cores and 24 threads (no hyperthreading), a base clock of 2.70 GHz, and a boost clock of 5.40 GHz, this Arrow Lake-HX chip is designed for high-performance mobile gaming and content creation. Its 36 MB of shared L3 cache and dual-channel DDR5 memory support with 102.4 GB/s bandwidth provide the data throughput needed to keep the RTX 4090 fed with draw calls and physics calculations.

The CPU's benchmark results are impressive across the board. Cinebench R23 multi-core score of 35,589 and single-core score of 2,204 demonstrate strong both-threaded and single-threaded performance. Geekbench scores of 20,795 multi-core and 2,458 single-core reinforce this picture. The PassMark multithread score of 55,759 and single-thread score of 4,713 place the chip in the 94th percentile against all CPUs, with an average benchmark score of 67,469. Its nearest rivals include the Intel Xeon w5-3525 (deltaPct -0.3), AMD EPYC 4484PX (deltaPct -0.5), and AMD Ryzen Threadripper PRO 5955WX (deltaPct -0.6), indicating the Core Ultra 9 sits in rarefied company—these are workstation and server-class processors, not typical laptop chips.

In Overpower specifically, the CPU's role becomes evident when examining the 1080p results. At Low settings, the system achieves 213 FPS, which is a high enough frame rate that the CPU's per-core performance and cache hierarchy are likely the gating factors. The single-core Cinebench R23 score of 2,204 suggests strong single-threaded capability, but 24 cores at 5.40 GHz boost can still be taxed by game logic and physics threads. The fact that 1080p Low (213 FPS) is only 10.8% faster than 1440p Low (190 FPS), despite a 44% reduction in pixel count, points to the CPU becoming a more significant constraint at lower resolutions.

How This Combo Ranks

This specific combination of Intel Core Ultra 9 275HX and NVIDIA GeForce RTX 4090 holds a combo rank of 602 out of 2,980 tested combos in Overpower. That places it in the top 20.2% of all combinations in the database, which is strong but not the absolute top tier. Given that both components are high-end—the CPU in the 94th percentile and the GPU in the 88th percentile—the combo rank suggests that other pairings, likely with desktop-class components or newer generations, outperform this mobile-focused setup.

The gap between individual component percentiles and the combo rank is telling. The CPU's 94th percentile and GPU's 88th percentile would naively suggest a top-10% combo, yet the actual rank of 602 indicates that in Overpower specifically, other factors matter. This could be due to the game's optimization for certain architectures, thermal throttling in mobile chassis, or the fact that the RTX 4090's end-of-life status means newer GPUs in the database have surpassed it. The measured FPS data shows the combo is capable of 213 FPS at 1080p Low and 78 FPS at 4K Ultra, which are solid numbers, but the rank suggests there are 601 other combos that achieve higher average performance in this title.

Q: Is the CPU or GPU more likely to bottleneck at 1080p?

A: The data suggests the CPU becomes more of a limiting factor at 1080p. The frame rate difference between 1080p Low (213 FPS) and 1440p Low (190 FPS) is only 23 FPS, whereas the pixel count increases by 77.8% between these resolutions, indicating the GPU is not fully utilized at 1080p.

Q: What are the minimum FPS values recorded?

A: Minimum FPS values were only recorded for Medium settings. At 1920x1080 Medium, the minimum is 113 FPS; at 2560x1440 Medium, it's 101 FPS; and at 3840x2160 Medium, it's 86 FPS. No minimum values were recorded for Low, High, or Ultra settings.

Q: How does this combo rank compared to other tested combinations?

A: The combo ranks 602nd out of 2,980 tested combos in Overpower, placing it in the top 20.2% of all combinations. This is respectable but not the top tier, despite the individual components ranking in the 88th-94th percentiles.

Q: What memory bandwidth does the RTX 4090 provide, and does it matter?

A: The RTX 4090 provides 1.01 TB/s of memory bandwidth from 24 GB of GDDR6X on a 384-bit bus. This high bandwidth is likely why the frame rate only drops by approximately 24% when moving from 1080p to 4K across all settings, as the GPU can fetch textures and geometry without stalling.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest performance. Low settings produce an average of 213 FPS, Medium drops to 133 FPS with a minimum of 113 and maximum of 153, High reaches 123 FPS, and Ultra manages 102 FPS. The spread from Low to Ultra is 111 FPS, indicating that settings have a substantial impact at this resolution.

Moving to 2560x1440, the averages are 190 FPS at Low, 118 FPS at Medium (min 101, max 136), 110 FPS at High, and 91 FPS at Ultra. The gap between Low and Ultra narrows to 99 FPS, and the 1440p results are consistently 10-13% lower than their 1080p counterparts across settings.

At 3840x2160, the averages fall to 161 FPS at Low, 101 FPS at Medium (min 86, max 116), 93 FPS at High, and 78 FPS at Ultra. The Low-to-Ultra spread compresses to 83 FPS, and the 4K numbers represent a 24.4%, 24.1%, 24.4%, and 23.5% reduction from 1080p for Low, Medium, High, and Ultra respectively. This consistency across presets suggests that resolution scaling is uniform regardless of graphics load, a sign of a well-balanced system where neither component becomes a disproportionate bottleneck at higher resolutions.

Settings Recommendations

For players targeting the highest possible frame rates, particularly for competitive play, Low settings at 1080p deliver 213 FPS, which exceeds the refresh rate of most high-end gaming displays. However, the jump to Medium at 1080p (133 FPS) still provides a smooth experience while likely offering significantly improved visual fidelity. The Medium preset also provides the only recorded minimum FPS data, with 113 at 1080p, 101 at 1440p, and 86 at 4K—all above the 60 FPS threshold for playable performance.

At 1440p, which is the sweet spot for many gaming laptops, Medium delivers 118 FPS average with a 101 FPS minimum, making it the recommended choice for balance. High at 1440p (110 FPS) is nearly as strong and may offer better visual quality without a major frame rate penalty. At 4K, Medium (101 FPS) is the clear recommendation, as it maintains triple-digit averages while Ultra (78 FPS) and High (93 FPS) are also playable options for those prioritizing visuals over smoothness.

The data shows that Ultra settings carry a significant cost—roughly 23-24% lower FPS than Medium across all resolutions—for what may be marginal visual improvements. For most players, Medium or High at 1440p provides the best experience, with 4K Medium offering a viable path to high-resolution gaming without sacrificing the frame rate headroom needed for action sequences. Low settings are only advisable for maximum frame rate at 1080p, as the 213 FPS result indicates the system has headroom to spare in less demanding scenarios.
