Roblox

The Intel Core Ultra 7 155H paired with the NVIDIA GeForce RTX 5080 produces a combination that ranks at position 1024 out of 3711 tested combos in Roblox. This places the pairing in the top 27.6 percent of all tested configurations, a strong result that underscores the hardware's capability in this specific sandbox title. The ranking reflects a system that is substantially higher-performing than the median tested combo, yet it does not reach the absolute apex of the leaderboard, indicating that while the hardware is potent, other factors such as game engine limitations or specific component bottlenecks prevent it from claiming a top-tier position.

The data suggests that this combo is not merely adequate but is positioned to deliver a high-refresh-rate experience. With a percentile rank of 83 for the CPU against all tested CPUs and 87 for the GPU against all tested GPUs, both components are individually in the upper echelon of their respective categories. This dual strength translates into a system that is well-balanced for Roblox, where neither the processor nor the graphics card is likely to be a glaring weak point. The rank of 1024, while not elite, reflects the fact that this pairing offers a level of performance that is far above what the majority of users would experience, making it a formidable setup for both competitive and casual play.

CPU Role

The Intel Core Ultra 7 155H serves as the central processing unit in this combo, and its specifications are directly relevant to the frame rates observed in Roblox. The processor is a 16-core, 22-thread part from the Meteor Lake architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. This high core count and thread count are notable, but for a game like Roblox, which often relies on single-threaded performance for its core simulation logic, the boost clock of 4.80 GHz is the more critical figure. The CPU's single-core performance is evidenced by its Cinebench R23 single-core score of 1743, which is a solid result that ensures the game's primary simulation thread has ample headroom to run without causing a bottleneck.

However, the CPU's multi-core capabilities are also relevant when Roblox loads complex worlds with many active scripts and physics interactions. The Cinebench R23 multicore score of 15028 and a Passmark multithread score of 24873 indicate that the 155H can handle these heavier workloads effectively. The processor's L3 cache of 24 MB (shared) helps in maintaining fast access to frequently used data, reducing the potential for stutters in busy scenes. In comparison to its nearest rivals, the Core Ultra 7 155H is effectively tied with the Intel Core i5-14600T and AMD Ryzen AI 7 PRO 360, with a deltaPct of 0 and 0.1, respectively. It also performs within 0.4 percent of the AMD Ryzen 7 PRO 6850H, showing that its overall computational throughput is on par with these alternatives.

The relationship between the CPU and the game's performance becomes clear when examining the FPS data across different settings. At 1920x1080, the highest frame rates are achieved, with an average of 495 FPS on Low settings. This indicates that at this resolution, the CPU is capable of feeding the GPU enough data to render frames at an exceptionally high rate. The fact that the FPS drops when moving to higher resolutions, such as 3840x2160, suggests that the load shifts to the GPU, but the CPU does not appear to be a limiting factor at any tested setting. The 155H's performance in this game is strong enough to keep up with the RTX 5080, ensuring that the GPU is not starved of data, which is a key requirement for achieving the high frame rates seen in the benchmark results.

Settings Recommendations

Based on the measured FPS data, the optimal experience in Roblox with this hardware depends on the user's priority: maximum smoothness or maximum visual fidelity. The data provides clear guidance on which preset delivers the best experience per the measured rows. For users with a high refresh rate monitor (e.g., 240Hz or 360Hz), the Low settings preset at 1920x1080 provides an average of 495 FPS, which is the highest measured value. This setting is ideal for competitive play where frame rate is paramount, as it ensures that the display is fed with a continuous stream of frames that can exceed the capabilities of most monitors.

However, for those who prefer a balance between visual quality and performance, the Medium preset at 1920x1080 offers an average of 450 FPS, with a minimum frame rate of 383 FPS and a maximum of 518 FPS. This is still an exceptionally high frame rate and provides a more visually appealing experience than Low settings. The High preset at 1080p yields 398 FPS, which is also very playable. Moving to 2560x1440, the Medium preset is the sweet spot, delivering 301 FPS on average, with a minimum of 256 FPS and a maximum of 346 FPS. This resolution is a good compromise for users who want a sharper image without sacrificing too much performance.

At 3840x2160 (4K), the Medium preset delivers 170 FPS on average, with a minimum of 145 FPS and a maximum of 196 FPS. This is a solid experience for 4K gaming, especially on a 144Hz monitor. The High preset at 4K drops to 150 FPS, which is still fluid, but the Ultra preset at 4K yields 122 FPS. The data indicates that the Medium preset is the most versatile choice across all resolutions, offering a significant reduction in frame rate compared to Low but a substantial increase in visual detail. The Ultra preset, while visually impressive, cuts the frame rate by a significant margin compared to Medium, making it less suitable for high-refresh-rate displays. Therefore, the recommendation is to use the Medium preset for the best overall balance, with the Low preset reserved for scenarios where hitting the highest possible frame rate is the primary objective.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how this combo performs across three resolutions and four settings presets. Starting at 1920x1080, the performance is exceptionally high across the board. On Low settings, the average FPS is 495, which is the peak performance for this combo. Medium settings produce an average of 450 FPS, with a minimum of 383 FPS and a maximum of 518 FPS. High settings yield 398 FPS, and Ultra settings drop to 323 FPS. These numbers demonstrate that at 1080p, the RTX 5080 is not severely stressed, and the CPU is doing its part to maintain high frame rates. The delta between Low and Ultra is 172 FPS, showing that the visual settings have a substantial impact on performance even at this resolution.

Moving to 2560x1440, the frame rates remain very high. The Low preset delivers an average of 330 FPS. The Medium preset achieves 301 FPS on average, with a minimum of 256 FPS and a maximum of 346 FPS. High settings produce 266 FPS, while Ultra settings drop to 216 FPS. The trend is consistent: each step up in settings reduces the frame rate by a noticeable margin. The transition from 1080p to 1440p shows a significant drop in performance, with the Low preset falling from 495 to 330 FPS, a reduction of 33 percent. This indicates that the GPU is becoming more of a limiting factor as the pixel count increases, but the overall performance is still excellent for high-refresh-rate gaming.

At 3840x2160, the performance is still very playable but shows a marked decrease. The Low preset averages 187 FPS. The Medium preset is the only one with a full range of data, showing an average of 170 FPS, a minimum of 145 FPS, and a maximum of 196 FPS. High settings produce 150 FPS, and Ultra settings drop to 122 FPS. The gap between Low and Ultra at this resolution is 65 FPS, which is a smaller absolute difference than at 1080p but represents a similar percentage drop. The minimum FPS of 145 on Medium at 4K is still well above the 60 FPS threshold for smooth gameplay, indicating that this combo can handle Roblox at 4K with a high degree of consistency. The data shows a clear hierarchy: 1080p is for maximum frame rates, 1440p is for a balance, and 4K is for visual fidelity with still-high performance.

Resolution Scaling

The FPS data reveals a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1920x1080 on the Medium preset, the average FPS is 450. This drops to 301 FPS at 2560x1440, a reduction of 33 percent. Moving from 1440p to 4K, the average FPS on Medium drops from 301 to 170, a reduction of 43.5 percent. This pattern indicates that the GPU is becoming increasingly taxed as the pixel count grows, which is a typical characteristic of a high-performance GPU like the RTX 5080. The CPU's role is to provide data to the GPU, and at 1080p, the CPU is able to supply frames faster than the GPU can render them, leading to the high frame rates observed.

The scaling from 1080p to 1440p shows a significant drop, which suggests that the GPU's rendering workload is the primary factor limiting performance at these higher resolutions. The RTX 5080, with its 16 GB of GDDR7 memory and 960.0 GB/s bandwidth, is a powerful card, but the sheer number of pixels at 4K (8.3 million) is a demanding task. The fact that the frame rate does not drop proportionally with the resolution increase (e.g., 4K has 4 times the pixels of 1080p, but the FPS does not drop to one quarter) indicates that other factors, such as memory bandwidth and fill rate, are also playing a role. The data suggests that this combo is capable of maintaining high frame rates at all resolutions, but the limiting component shifts from the CPU at 1080p to the GPU at 1440p and 4K. The performance drop is not linear, which is a sign that the system is well-balanced and that the RTX 5080 is the primary driver of performance at higher resolutions, while the CPU remains capable of keeping up.

GPU Role

The NVIDIA GeForce RTX 5080 is the primary driver of visual performance in this combo, and its specifications are critical to understanding the frame rates achieved. The GPU is based on the Blackwell 2.0 architecture and features 10752 shading units, 336 texture mapping units, and 112 render output units. It has a base clock of 2295 MHz and a boost clock of 2617 MHz. These high clock speeds, combined with the large number of cores, allow the card to process the relatively simple geometry and textures of Roblox at an extremely rapid pace. The GPU's 16 GB of GDDR7 memory on a 256-bit bus provides a bandwidth of 960.0 GB/s, which is more than sufficient for the game's asset streaming needs, even at 4K resolution.

The GPU's performance in synthetic benchmarks corroborates its strong showing in Roblox. It scores 36565 in Passmark G3D, which is a high score, and achieves 8637 in 3DMark Steel Nomad DX12. These numbers indicate a very capable card that is near the top of its class. In comparison to its nearest rivals, the RTX 5080 is 0.6 percent ahead of the AMD Radeon 8060S and 0.7 percent ahead of the AMD Radeon RX 6750 GRE 12 GB. It is also 2.3 percent ahead of the AMD Radeon Pro W5700X, but it trails the AMD Radeon RX 9070 GRE by 2.2 percent. This shows that while the RTX 5080 is a high-performance card, it is not the absolute fastest in its immediate peer group.

The GPU's role becomes more prominent as resolution increases. At 1080p, the GPU is not the bottleneck, as the CPU can generate frames faster than the GPU can render them. However, at 1440p and especially at 4K, the GPU's workload increases significantly, and its performance directly dictates the frame rates. The data shows that the RTX 5080 is powerful enough to deliver over 120 FPS at 4K even on Ultra settings, which confirms its capabilities. The GPU's 84 ray tracing cores and 336 tensor cores are not heavily utilized in Roblox, which is not a ray tracing-heavy title, but they contribute to the card's overall versatility. The RTX 5080's role is to ensure that the game looks as good as possible while maintaining high frame rates, and the measured data confirms that it excels at this task.
