Hitman 2

Hitman 2 presents an interesting paradox for the Intel Core Ultra 5 125H paired with the NVIDIA GeForce RTX 4090. The benchmark data shows a system where the GPU is ostensibly the star, yet the CPU consistently caps performance in lower-resolution scenarios. The measured FPS figures reveal a steep scaling curve that shifts from a CPU-bound plateau at 1080p to a GPU-bound cliff at 4K. This analysis breaks down how the combination of a mobile processor and a flagship desktop GPU behaves across settings and resolutions, providing a clear picture of where the bottleneck lies and how to optimize the experience.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic and reveals a classic dual-bottleneck scenario. At 1920x1080 with High settings, the system delivers 135 FPS. Moving to 2560x1440 reduces that to 86 FPS, a 36% decrease. The jump to 3840x2160 further craters performance to 46 FPS, which is a 66% reduction from the 1080p baseline. This scaling pattern indicates that at 1080p, the Intel Core Ultra 5 125H is the limiting factor; the RTX 4090 has ample headroom but is starved by the CPU's single-thread capabilities. As resolution increases, the rendering load on the GPU grows, and the bottleneck shifts. At 4K, the data suggests the RTX 4090 is finally being pushed to its limits, as the frame rate drops to a level that aligns more closely with the GPU's raw compute capabilities.

The trend continues across all settings. For Low settings, the system hits 238 FPS at 1080p, but this falls to 152 FPS at 1440p and then plummets to 81 FPS at 4K. The 4K Low result is particularly telling: it is only 34% of the 1080p Low score. This massive drop at 4K, even on Low, confirms that the RTX 4090 is the primary constraint at that resolution, as the reduced CPU load at Low settings cannot compensate for the sheer pixel count. Conversely, at 1080p, the delta between Low and Ultra is 139 FPS (238 vs 99), which is a smaller gap than the resolution scaling, suggesting that CPU limitations are flattening the performance curve regardless of GPU load.

The data shows that the system is most balanced at 2560x1440. At Medium settings, the system achieves 114 FPS, and the scaling from 1080p (178 FPS) to 1440p (114 FPS) represents a 36% drop, which is a more moderate and playable degradation. This resolution appears to be the sweet spot where the CPU and GPU workloads are more evenly matched, allowing the RTX 4090 to stretch its legs without being completely constrained by the Ultra 5 125H. At 4K, the system's performance collapses, with even High settings only managing 46 FPS, indicating that this combination is not suited for native 4K gaming in Hitman 2.

Settings Recommendations

For the best experience per the measured rows, the Medium preset at 2560x1440 offers the most compelling balance. The data shows 114 FPS average with a minimum of 97 FPS and a maximum of 131 FPS. This combination provides a smooth, high-refresh-rate experience that is well above the 60 FPS threshold, while the minimum FPS figure suggests consistent frame pacing without severe stutters. While High at 1440p is also playable at 86 FPS, the Medium preset's 114 FPS average is a significant 33% improvement and comes with a more stable frame time envelope, as indicated by the recorded minimum.

At 1920x1080, the Medium preset is the clear winner. It delivers 178 FPS average with a minimum of 152 FPS, which is exceptionally smooth. While Low settings push higher to 238 FPS, the visual quality trade-off is substantial for a game like Hitman 2, where environmental detail and crowd density matter. High at 1080p yields 135 FPS, but the jump to Medium is only 43 FPS higher and provides a better frame rate buffer. Ultra at 1080p drops to 99 FPS, which is still playable, but the performance cost of Ultra over Medium (a 79 FPS deficit) is not justified by the visual gains in this CPU-bound scenario.

For 4K, the data discourages high-end presets. Ultra is unplayable at 34 FPS, and High is marginal at 46 FPS. Low settings at 81 FPS are the only viable option for 4K, but this sacrifices most graphical fidelity. The recommendation is clear: stick to 1440p Medium for the best overall experience, or 1080p Medium if you prioritize frame rates above all else. The 4K resolution should be avoided unless you are willing to accept Low settings, as the system simply does not have the CPU headroom to feed the RTX 4090 adequately at that resolution.

GPU Role

The NVIDIA GeForce RTX 4090 is a monstrous piece of silicon, but its role in this pairing is often wasted. The GPU features 24 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 1.01 TB/s. This vast memory pool is more than sufficient for Hitman 2 at any resolution, as the game's textures and geometry are unlikely to exceed even half of that capacity. The card's boost clock of 2520 MHz and its Ada Lovelace architecture with 16,384 shading units are theoretically capable of far higher frame rates than those recorded.

The benchmark results indicate that the RTX 4090 is severely underutilized at 1080p. The fact that Low settings yield 238 FPS and Ultra yields 99 FPS at the same resolution suggests that the GPU is not the bottleneck; otherwise, the Ultra score would be much closer to the Low score. The GPU's percentile ranking of 88 and its average benchmark score of 60347 place it in the top tier, but in this game, it is often waiting on the CPU. The PassMark G3D score of 38194 highlights its raw power, yet the measured FPS in Hitman 2 at 4K High (46 FPS) is surprisingly low for such a capable card.

The role of the GPU becomes more apparent at 4K. The drop from 81 FPS at Low to 46 FPS at High shows the GPU is finally being loaded, but the scaling is still poor. The RTX 4090's 24 GB VRAM is a future-proofing asset, but for Hitman 2, it provides no tangible benefit over a smaller pool. The card's memory clock of 1313 MHz and 21 Gbps effective speed are adequate, but the data suggests that the GPU's performance is being capped by the CPU's inability to issue draw calls quickly enough. The result is a system that can brute-force 4K at Low settings but cannot deliver a premium 4K experience due to the processor bottleneck.

FAQ

Q: Why does the system perform so poorly at 4K Ultra (34 FPS) despite having an RTX 4090?

A: The benchmark data shows that the Intel Core Ultra 5 125H cannot feed the RTX 4090 enough data at high resolutions. The CPU's low single-thread performance (Cinebench R23 single-core score of 1647.5) becomes a bottleneck, preventing the GPU from reaching its full potential. Even at 4K High, the FPS only reaches 46, indicating that the CPU is still limiting the frame rate.

Q: Is the RTX 4090 worth pairing with this CPU for Hitman 2?

A: Based on the measured FPS, the RTX 4090 is overkill for this game at 1080p and 1440p. At 1080p High, the system achieves 135 FPS, which is likely below what the GPU could deliver with a stronger processor. The GPU's performance is only fully utilized at 4K Low (81 FPS), but even then, the results are not impressive for a card of this class.

Q: What is the best resolution for this CPU-GPU combo in Hitman 2?

A: The data shows that 2560x1440 with Medium settings provides the best balance, delivering 114 FPS average with a minimum of 97 FPS. This resolution allows the RTX 4090 to do more work than at 1080p, while the CPU can still keep up. Higher resolutions cause a steep drop-off, and lower resolutions leave GPU performance on the table.

Q: How does the Ultra 5 125H compare to its closest rivals in CPU benchmarks?

A: The Intel Core Ultra 5 125H has an average benchmark score of 27507, which is nearly identical to the AMD Ryzen 7 5800 (27535) and Intel Core i5-12600K (27578), with delta percentages of -0.1% and -0.3% respectively. It slightly outperforms the AMD Ryzen 3 PRO 5355G by 0.5%. This indicates that its CPU processing power is on par with mid-range desktop chips from a few generations ago.

Q: Does the 24 GB of VRAM on the RTX 4090 help in Hitman 2?

A: The measured FPS data does not indicate any VRAM-related performance issues. At 4K Ultra, the system only achieves 34 FPS, which is a performance limit, not a capacity limit. The 24 GB pool is far larger than what Hitman 2 requires, so the VRAM size does not influence the results. The card's compute capabilities are the relevant factor, and those are being bottlenecked by the CPU.

Q: Should I use Low settings at 4K or Medium settings at 1440p?

A: The benchmark data strongly favors 1440p Medium. That setting yields 114 FPS with a minimum of 97 FPS, while 4K Low yields 81 FPS. The 1440p Medium configuration provides a higher average frame rate, a higher minimum frame rate, and significantly better visual quality, making it the superior choice for gameplay smoothness and fidelity.

CPU Role

The Intel Core Ultra 5 125H is a 14-core, 18-thread mobile processor based on the Meteor Lake architecture. Its base clock of 3.60 GHz and boost clock of 4.50 GHz are modest for gaming, and its Cinebench R23 single-core score of 1647.5 is the critical weakness. In Hitman 2, which relies heavily on single-thread performance for game logic and draw call submission, this CPU becomes the primary limiting factor at lower resolutions.

The data shows that at 1080p, the system's FPS is largely independent of GPU load. The RTX 4090 is capable of much higher frame rates, but the CPU's 18 threads cannot process the game's instructions fast enough. The Ultra 5 125H's PassMark single-thread score of 3399 and its percentile ranking of 79 (versus all CPUs) indicate it is a competent mid-range processor, but it is not in the same league as the desktop-class CPUs typically paired with an RTX 4090. The CPU's 18 MB of shared L3 cache is adequate, but the data suggests that raw clock speed and IPC are more important for this game.

The CPU's role shifts at 4K, where the GPU becomes the bottleneck. At 4K Low, the system achieves 81 FPS, which is a 66% drop from 1080p Low (238 FPS). This drop is more attributable to the GPU's pixel-pushing limits than the CPU. However, the CPU still constrains the maximum FPS, as the 4K Ultra score of 34 FPS is likely lower than what the GPU could achieve with a faster processor. The Cinebench R20 multi-core score of 7161 shows the CPU can handle multi-threaded workloads, but Hitman 2 does not scale well with more cores, so this strength is not fully utilized. The result is a system where the CPU's single-thread speed is the ceiling for performance in most scenarios.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings hit an average of 238 FPS. Medium settings reduce this to 178 FPS, with a minimum of 152 FPS and a maximum of 205 FPS. High settings achieve 135 FPS, and Ultra drops to 99 FPS. The scaling from Low to Ultra is a 58% reduction, but even the Ultra score is playable. The narrow gap between Medium and High (43 FPS) and the larger gap between High and Ultra (36 FPS) suggest diminishing returns at the top end.

At 2560x1440, performance takes a noticeable hit. Low settings average 152 FPS. Medium settings deliver 114 FPS, with a minimum of 97 FPS and a maximum of 131 FPS. High settings manage 86 FPS, and Ultra falls to 64 FPS. The Medium preset's minimum of 97 FPS indicates that it can hold a stable frame rate, making it the most reliable option at this resolution. The drop from High to Ultra is 22 FPS, which is a significant cost for visual improvements.

At 3840x2160, the system struggles. Low settings are the only playable option, averaging 81 FPS. Medium settings drop to 61 FPS, with a minimum of 52 FPS and a maximum of 70 FPS, which is borderline playable. High settings average 46 FPS, and Ultra averages just 34 FPS. The 4K data shows a clear cliff: the gap between Low and Medium is 20 FPS, while the gap between High and Ultra is only 12 FPS, indicating that the GPU is maxed out and the CPU cannot compensate. The measured FPS at 4K Ultra (34 FPS) is the lowest score recorded, confirming that this CPU-GPU combination is not viable for high-fidelity 4K gaming.
