Roblox

Roblox is a uniquely scalable title, and the measured results for the Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 5060 illustrate a system that is heavily bound by the graphics processor at higher resolutions, yet transitions to a more balanced state at 1080p. The data shows a clear and consistent pattern: as resolution drops, frame rates rise dramatically, indicating that the GPU is the primary limiting factor in this configuration.

Resolution Scaling

The frame rate progression from 4K down to 1080p is steep and tells a clear story about where the bottleneck lies in this system. At 4K with High settings, the combo produces an average of 96 FPS. Dropping to 1440p High increases that average to 169 FPS, a substantial jump of 73 FPS. Moving further down to 1080p High, the average reaches 254 FPS. This scaling pattern—where performance nearly doubles from 4K to 1080p—is characteristic of a GPU-bound scenario, where the render resolution directly dictates the workload on the graphics card.

The relationship is even more pronounced at the lower settings presets. With Low settings, the system moves from 119 FPS at 4K to 210 FPS at 1440p, and finally to 315 FPS at 1080p. The fact that the 1080p Low result is nearly three times the 4K Low result confirms that the RTX 5060 is being tasked with progressively less pixel-pushing work as resolution decreases. The game engine is able to exploit the additional bandwidth and pixel throughput at lower resolutions, but the frame rate ceiling at 1080p suggests that other components, namely the CPU, are beginning to play a more significant role.

The delta between resolutions is not perfectly linear, which hints at the architecture of the game. For instance, at Medium settings, the difference between 4K (108 FPS) and 1440p (191 FPS) is 83 FPS, while the difference between 1440p and 1080p (287 FPS) is 96 FPS. This non-linear scaling is typical of a title where the CPU begins to assert its influence as the GPU load diminishes. The measured minimum and maximum frame rates at Medium settings further illustrate this: at 1080p, the range is 244 to 330 FPS, a spread of 86 FPS, whereas at 1440p the range is 163 to 220 FPS. The wider variance at 1080p indicates that the frame delivery is becoming less consistent, likely due to CPU-driven frame pacing fluctuations rather than pure GPU throughput.

GPU Role

The NVIDIA GeForce RTX 5060 is the dominant force in this pairing, and its specifications align with the observed performance scaling. The GPU operates with a base clock of 2280 MHz and a boost clock of 2497 MHz, built on the Blackwell 2.0 architecture with a 5 nm process. It features 8 GB of GDDR7 memory on a 128-bit bus, providing a bandwidth of 448.0 GB/s. These characteristics are sufficient for the demands of Roblox at high frame rates, but the data shows that the GPU is the component that capitulates first when resolution increases.

At 4K Ultra, the average FPS drops to 78, which is the lowest figure recorded across all tests. This represents a 19% decrease from the 4K High preset (96 FPS) and a 34% decrease from the 4K Low preset (119 FPS). The relatively modest memory size of 8 GB does not appear to be a hard limit at these settings, as the game still runs, but the pixel fill rate and shader workload clearly overwhelm the GPU. The 19.18 TFLOPS of FP32 performance and the 119.9 GPixel/s pixel rate are being fully utilized at 4K, and the results show that the card is unable to maintain high frame rates under that load.

In contrast, the GPU's capabilities are more than adequate at 1080p. The average FPS at 1080p Ultra is 206, which is nearly triple the 4K Ultra figure. This indicates that the RTX 5060 has ample headroom for Roblox's graphical demands when the resolution is constrained. The data suggests that the GPU is not the limiting factor at 1080p; rather, it is being fed frames faster than the CPU can process the game's logic. The benchmark results for the GPU show a Passmark G3D score of 20891 and a percentile ranking of 72 among all GPUs, placing it in a solid mid-to-upper tier position, which is consistent with its ability to handle 1080p and 1440p gaming with ease.

Settings Recommendations

The measured FPS data provides a clear path for optimizing the experience in Roblox with this hardware. For users with a 4K display, the High preset is the recommended choice. It delivers an average of 96 FPS, which is playable, while the Ultra preset drops to 78 FPS, a more noticeable decrease in smoothness. The Low preset at 4K offers a higher 119 FPS but sacrifices visual fidelity for a performance gain that may not be necessary given the High preset's acceptable frame rate.

At 1440p, the Medium preset presents the best balance between visual quality and performance. It achieves an average of 191 FPS with a minimum of 163 FPS, ensuring a consistently fluid experience. The High preset at 169 FPS is also viable, but the Medium preset provides a 22 FPS advantage with likely minimal visual difference in a game like Roblox. The Ultra preset at 137 FPS is still smooth, but the jump in settings is not worth the 54 FPS drop from Medium.

For 1080p users, the Ultra preset is the clear winner. It produces an average of 206 FPS, which is well above the refresh rate of most modern monitors. The High preset at 254 FPS and Medium at 287 FPS offer even higher numbers, but the visual improvements from the Ultra preset are more valuable than chasing frame rates beyond 200 FPS. The Low preset at 315 FPS is unnecessary for a competitive advantage in this game and will degrade the experience visually. The data supports that the system can handle the Ultra preset at 1080p without any risk of dropping below the 244 FPS minimum seen at Medium settings.

Measured FPS Breakdown

The complete dataset for this combo reveals a consistent hierarchy across all resolutions and settings. At 3840x2160, the Low preset leads with 119 FPS average, followed by Medium at 108 FPS (with a min of 92 and max of 125), High at 96 FPS, and Ultra at the bottom with 78 FPS. The progression at this resolution is orderly, with each step up in settings costing roughly 10-20 FPS.

At 2560x1440, the order remains the same but the gaps widen. Low averages 210 FPS, Medium averages 191 FPS (min 163, max 220), High averages 169 FPS, and Ultra averages 137 FPS. The difference between Low and Ultra is a substantial 73 FPS, showing that the GPU is still being taxed heavily at this mid-range resolution.

The 1920x1080 results show the highest frame rates and the largest absolute differences. Low averages 315 FPS, Medium averages 287 FPS (min 244, max 330), High averages 254 FPS, and Ultra averages 206 FPS. The gap between Low and Ultra expands to 109 FPS. Interestingly, the minimum FPS at Medium settings (244 FPS) is higher than the average FPS at Ultra settings (206 FPS), indicating that even the most demanding preset at 1080p is not causing the system to struggle with frame drops below what the Medium preset can deliver.

CPU Role

The Intel Core Ultra 7 155H is a capable mobile processor, but its role in Roblox is secondary to the GPU. The CPU features 16 cores and 22 threads, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. It has a 24 MB shared L3 cache and supports DDR5 memory with a bandwidth of 89.6 GB/s. In synthetic benchmarks, it scores 15028 in Cinebench R23 multicore and 1743 in single-core, with a Passmark single-thread score of 3468. Its average benchmark score of 32697 places it in the 83rd percentile of all CPUs.

These numbers indicate a processor with strong multi-threaded and adequate single-threaded performance. However, Roblox is known to be sensitive to single-core performance, and the data suggests that at 1080p, the CPU's single-thread capabilities are the next bottleneck after the GPU. The fact that the frame rate scales from 206 FPS at 1080p Ultra to 315 FPS at 1080p Low shows that the GPU is still doing most of the work, but the 109 FPS difference between these presets is smaller than the 158 FPS difference seen between 4K High and 1080p High. This compression of frame rates at 1080p points to the CPU becoming a more significant factor as the GPU load decreases.

The CPU's nearest rivals in the benchmark database include the Intel Core i5-14600T and the AMD Ryzen AI 7 PRO 360, which have nearly identical average scores (32707 and 32662, respectively). The Core Ultra 7 155H is within 0.2% of these parts, showing that it is a mid-pack performer in its class. For Roblox, this level of CPU performance is sufficient to feed the RTX 5060 at 1080p, but it is not so powerful that it removes the GPU bottleneck entirely.

How This Combo Ranks

The combination of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 5060 holds a combo rank of 2450 out of 3711 tested configurations in Roblox. This places it in the lower third of all combos, which is a surprising result given the high frame rates measured. The ranking is likely influenced by the fact that Roblox is a game where many lower-end CPUs paired with high-end GPUs can achieve very high frame rates, pushing this mid-range combo down the list.

The relative position suggests that while the absolute performance is strong—averaging over 200 FPS at 1080p—there are many other tested combos that achieve even higher numbers, likely due to more powerful CPUs or GPUs. The data shows that this combo is not in the top tier for Roblox, but it is far from the bottom. The GPU's percentile ranking of 72 and the CPU's percentile of 83 are both respectable, but the combo's overall rank of 2450 indicates that the combination does not synergize as well as some other pairings in this specific title.

The benchmark results show that this system is well-suited for 1440p and 1080p gaming in Roblox, offering excellent frame rates at those resolutions. The 4K performance is acceptable but not exceptional, with the Ultra preset falling below 80 FPS. For a user prioritizing high refresh rate gaming at 1080p, this combo is more than adequate, but for those seeking to maximize 4K fidelity, other configurations may rank higher. The data indicates that the RTX 5060 is the stronger component in this pairing, and the CPU, while competent, does not boost the combo into the upper echelons of the ranking table.
