Roblox

The Intel Core Ultra 7 155H is a 16-core, 22-thread mobile processor based on the Meteor Lake architecture, with a base clock of 3.80 GHz and a boost clock of 4.80 GHz. In synthetic benchmarks, its Cinebench R23 multi-core score of 15028 and single-core score of 1743 place it in the 83rd percentile of all CPUs, indicating strong overall compute capability. However, for a game like Roblox, which is not typically demanding on multi-threaded workloads, the data suggests that the processor’s high thread count is less critical than its capable single-core performance. The Passmark single-thread score of 3468 aligns with the processor’s boost clock, providing the responsiveness needed for the game’s physics and logic. The 24 MB of shared L3 cache further supports efficient data handling, but the measured frame rates show that at lower resolutions, the GPU becomes the primary bottleneck, as the CPU is capable of feeding frames well beyond what the display refresh rate can show.

The processor’s nearest rivals, based on average benchmark scores, include the Intel Core i5-14600T with a score of 32707 and a deltaPct of 0, and the AMD Ryzen AI 7 PRO 360 with a score of 32662 and a deltaPct of 0.1. The Intel Core Ultra 7 155H’s own average benchmark score is 32697, which places it essentially level with these competitors. The AMD Ryzen 5 7400F is slightly ahead at 32750, while the AMD Ryzen 7 PRO 6850H leads the group at 32812. In the context of Roblox, these differences in synthetic scores are unlikely to translate into meaningful frame rate differences, as the game’s engine is not heavily parallelized. The data indicates that the CPU is rarely the limiting component in this configuration, especially at 1080p where frame rates exceed 300 FPS on lower settings, demonstrating that the processor has ample headroom for the game’s requirements.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core Ultra 7 155H’s configuration of 16 cores and 22 threads is far more than Roblox requires, as the game typically scales well with a few strong cores rather than many weaker ones. The base clock of 3.80 GHz and boost clock of 4.80 GHz are the key specifications here, as they determine the processor’s ability to handle the game’s primary thread, which is responsible for rendering commands and game logic. The Cinebench R23 single-core score of 1743, which falls in the 83rd percentile, confirms that this chip has strong per-core performance, ensuring that the game’s main thread does not become a bottleneck. In contrast, the multi-core score of 15028 is more indicative of the processor’s ability to handle background tasks, which is less relevant for Roblox’s frame rate output.

The data shows that the CPU’s performance is sufficient to drive very high frame rates in Roblox, particularly at 1080p. At 1920x1080 with Low settings, the average FPS reaches 364, which is a clear indicator that the CPU can process game logic and issue draw calls faster than the GPU can render them at lower graphical loads. This is further supported by the fact that even at 4K with Ultra settings, the frame rate only drops to 90 FPS, suggesting that the CPU is not the limiting factor in any scenario tested. The processor’s 28 W TDP, while modest, does not appear to hinder its ability to maintain high clock speeds, as evidenced by the consistent frame rates across different resolutions.

Comparing to its nearest rivals, the Intel Core Ultra 7 155H is statistically tied with the Intel Core i5-14600T, which has an average score of 32707, and the AMD Ryzen AI 7 PRO 360, which scores 32662. The differences are within a fraction of a percent, with deltas of 0 and 0.1 respectively. This means that in a game like Roblox, swapping between these processors would yield no observable difference in frame rates, as the game is not sensitive to the marginal changes in multi-threaded performance. The AMD Ryzen 7 PRO 6850H, with a score of 32812 and a deltaPct of -0.4, is also effectively equivalent. The CPU’s role in this combo is to provide a stable, high-frequency platform that allows the RTX 4070 to operate at its full potential without being starved of data.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 is a discrete mobile GPU based on the Ada Lovelace architecture, featuring 5888 shading units and 12 GB of GDDR6X memory on a 192-bit bus. The memory clock runs at 1313 MHz, which translates to 21 Gbps effective, providing a bandwidth of 504.2 GB/s. For Roblox, this amount of VRAM is far beyond what the game requires, even at 4K Ultra settings, as the game’s assets are relatively simple and do not consume large amounts of video memory. The GPU’s boost clock of 2475 MHz is the primary driver of its performance, and the measured frame rates indicate that it is more than capable of handling the game’s graphical demands at all tested settings.

The GPU’s benchmark scores, such as a Passmark G3D score of 26927 and a 3DMark Steel Nomad DX12 score of 3854, place it in the 81st percentile of all GPUs. Its nearest rivals include the NVIDIA Tesla P4 with an average score of 37628 and a deltaPct of 0.1, and the AMD Radeon RX Vega 56 with a score of 37507 and a deltaPct of 0.4. The RTX 4070’s own average score is 37648, making it the leader of this group, while the NVIDIA GeForce RTX 4080 Mobile is slightly ahead at 38135 but with a negative deltaPct of -1.3, indicating that it outperforms the 4070 by a small margin. In Roblox, these synthetic differences are not fully utilized, as the game’s engine does not push the GPU to its limits in the same way that AAA titles do.

The GPU’s role becomes more apparent as resolution increases. At 1920x1080, the GPU is not the bottleneck, as frame rates exceed 290 FPS even on High settings. However, at 3840x2160, the frame rates drop to 111 FPS on High and 90 FPS on Ultra, which is still very playable but demonstrates that the GPU is being tasked more heavily. The 12 GB of VRAM is never a limiting factor, as the game does not require more than a few gigabytes, even at 4K. The GPU’s 29.15 TFLOPS of FP32 performance and 455.4 GTexel/s texture rate are more than sufficient for Roblox’s relatively simple shaders and textures. The data indicates that the GPU is the primary performance limiter at 4K, but it does so gracefully, maintaining smooth frame rates even at the highest settings.

Measured FPS Breakdown

The measured FPS data for this configuration covers three resolutions (1920x1080, 2560x1440, and 3840x2160) and four settings presets (Low, Medium, High, and Ultra). At 1080p, the performance is exceptionally high, with the Low preset achieving an average of 364 FPS, which is the highest frame rate recorded in the entire dataset. The Medium preset averages 332 FPS, with a minimum of 282 and a maximum of 381, showing that even with moderate graphical demands, the system maintains high frame rates with minimal variance. High settings average 293 FPS, while Ultra drops to 238 FPS, still far above the refresh rate of most displays. The progression from Low to Ultra at 1080p shows a 34.6% reduction in average FPS, from 364 to 238, indicating that the GPU is being taxed more heavily as graphical fidelity increases.

Moving to 2560x1440, the frame rates remain high but show a clear step down. The Low preset averages 243 FPS, which is 33.2% lower than the same setting at 1080p. Medium averages 221 FPS, with a minimum of 188 and a maximum of 254, demonstrating a tighter range than the 1080p Medium results. High settings average 196 FPS, while Ultra drops to 159 FPS. At this resolution, the gap between Low and Ultra is 84 FPS, or 34.6%, which is consistent with the percentage drop seen at 1080p. This suggests that the GPU is scaling predictably with resolution, and the CPU is still not the limiting factor.

At 4K (3840x2160), the frame rates become more moderate but remain playable. Low settings average 138 FPS, which is a significant drop from the 243 FPS at 1440p, representing a 43.2% reduction. Medium averages 125 FPS, with a minimum of 106 and a maximum of 144, showing that the GPU is now the clear bottleneck. High settings average 111 FPS, while Ultra drops to 90 FPS. The difference between Low and Ultra at 4K is 48 FPS, or 34.8%, which is remarkably consistent with the percentage differences at other resolutions. This consistency indicates that the game’s settings presets have a relatively uniform impact on GPU load, and the CPU’s performance is sufficient to maintain these frame rates without introducing stutter or frame time spikes.

How This Combo Ranks

The combo of the Intel Core Ultra 7 155H and the NVIDIA GeForce RTX 4070 ranks 1990 out of 3711 tested combinations for Roblox, placing it in the 54th percentile of all systems. This ranking is based on the measured FPS data, which shows that while the system is capable of very high frame rates, there are many combinations that perform even better, particularly those with higher-end desktop components or newer GPUs. The ranking is not indicative of poor performance, as the 1080p results show frame rates above 300 FPS, but the large number of tested combos means that even small differences in FPS can result in a mid-pack ranking.

The CPU’s percentile of 83 and the GPU’s percentile of 81 are both above average, but the combo’s ranking in the 54th percentile for Roblox suggests that the game itself may not be fully utilizing the hardware’s potential, or that other combos with higher-end GPUs (e.g., the RTX 4080 Mobile) achieve even higher frame rates. The nearest GPU rival, the RTX 4080 Mobile, has a deltaPct of -1.3, meaning it outperforms the RTX 4070 by 1.3% in synthetic benchmarks. In a game like Roblox, this small difference could translate to a few extra FPS, which might be enough to push a combo into a higher rank. The data shows that this combo is solidly mid-pack, offering high performance but not the absolute best frame rates available for Roblox.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the user’s display resolution and refresh rate. At 1080p, all settings presets deliver over 200 FPS on average, with Ultra still achieving 238 FPS. For a standard 144Hz or 165Hz monitor, the High preset (293 FPS) is more than sufficient, and the Ultra preset (238 FPS) is also viable if the user prefers higher graphical fidelity without sacrificing smoothness. The Medium preset (332 FPS) offers a good balance for users with high-refresh-rate displays (240Hz or higher), as it stays above the refresh rate threshold while providing better visuals than Low. The Low preset (364 FPS) is best for competitive play where maximum FPS is prioritized over visuals, but it is only necessary for 360Hz monitors.

At 1440p, the frame rates are lower but still very high. The High preset (196 FPS) is ideal for 144Hz displays, as it provides a comfortable margin above the refresh rate. The Medium preset (221 FPS) is suitable for 240Hz displays, while the Ultra preset (159 FPS) is still playable on 144Hz monitors but may show occasional dips if the refresh rate is not adaptive. The Low preset (243 FPS) is only beneficial for users with 240Hz or higher refresh rate displays. The data indicates that the GPU can handle 1440p High settings with ease, making it the recommended choice for most users at this resolution.

At 4K, the frame rates are more modest. The High preset (111 FPS) is the best choice for a 120Hz display, as it averages just below the refresh rate and will feel smooth with adaptive sync. The Medium preset (125 FPS) is also viable and offers a better experience on 120Hz displays, but the Ultra preset (90 FPS) is acceptable for 60Hz displays, which are still common at 4K. The Low preset (138 FPS) is only necessary for 144Hz 4K displays, which are less common. For the best experience at 4K, the Medium preset provides the highest average FPS (125) that stays comfortably above 60 FPS, making it the recommended choice for maximizing smoothness while maintaining decent visuals.

Resolution Scaling

The FPS data shows a clear and predictable scaling pattern as resolution increases from 1080p to 4K. At Low settings, the average FPS drops from 364 at 1080p to 243 at 1440p, a 33.2% reduction, and then to 138 at 4K, a 43.2% reduction from 1440p. This indicates that the GPU is the primary limiting factor at higher resolutions, as the CPU’s performance headroom is not fully utilized when the GPU is tasked with more pixels. The percentage drop from 1080p to 1440p is slightly less than the drop from 1440p to 4K, which is expected because 4K has four times the pixels of 1080p, while 1440p has only 1.78 times the pixels of 1080p.

For Medium settings, the frame rates follow a similar pattern: 332 FPS at 1080p, 221 FPS at 1440p (a 33.4% drop), and 125 FPS at 4K (a 43.4% drop from 1440p). The High settings show 293 FPS at 1080p, 196 FPS at 1440p (a 33.1% drop), and 111 FPS at 4K (a 43.4% drop). Ultra settings show 238 FPS at 1080p, 159 FPS at 1440p (a 33.2% drop), and 90 FPS at 4K (a 43.4% drop). The consistency of these percentage drops across all settings presets is notable, with the 1080p to 1440p drop being consistently around 33% and the 1440p to 4K drop being consistently around 43%. This suggests that the game’s rendering pipeline scales linearly with resolution, and the GPU’s performance is the sole determinant of frame rate at these higher resolutions.

The scaling analysis also reveals that the CPU is not the bottleneck at any resolution, as the frame rates continue to drop proportionally with resolution, which is a GPU-bound behavior. If the CPU were the limiting factor, the frame rate drop from 1440p to 4K would be less pronounced, as the CPU would cap the frame rate regardless of GPU load. The data shows that this combo is GPU-limited at 4K, with the RTX 4070’s performance being the determining factor. At 1080p, the CPU has sufficient headroom to drive frame rates above 300 FPS, but the GPU’s output is still the limiting factor, as even the Low preset cannot reach 400 FPS, indicating that the GPU’s raw pixel throughput is the ceiling for this configuration.
