Q: Where does this specific CPU+GPU combination rank among all tested combos for Roblox?

A: The combo ranks 1591 out of 3010 tested combinations. This places it in the 53rd percentile, which is surprisingly mid-pack for such high-end hardware, suggesting that other components or system configurations in the database achieve similar frame rates due to the game's performance ceiling.

GPU Role

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture and features 12 GB of GDDR6X memory on a 192-bit bus, yielding a bandwidth of 504.2 GB/s. Its base clock is 1920 MHz with a boost clock of 2475 MHz. In the context of Roblox, this GPU is a massive powerhouse. The measured FPS data shows that even at the most demanding preset (Ultra) and resolution (3840x2160), the card maintains an average of 90 FPS. This indicates that the GPU is not the bottleneck in most scenarios.

The GPU's role becomes more apparent when analyzing the scaling from 1080p to 4K. At Low settings, the frame rate drops from 364 to 138, a clear sign that the GPU is being tasked with more work as the resolution increases. However, the absolute performance is still stellar. The data implies that the RTX 4070's raw compute power, evidenced by its 29.15 TFLOPS FP32 performance, is more than sufficient to handle Roblox's rendering demands. The GPU's 81st percentile ranking among all GPUs and its proximity to the RTX 4080 Mobile (only 1.3% difference in average benchmark score) further solidify its high-end status.

Interestingly, the variance between settings at the same resolution is relatively small. At 4K, the difference between Low and High is only 27 FPS (138 vs. 111). This suggests that the GPU has enough headroom to absorb the increased graphical load from higher settings without a dramatic impact on performance. It is only at the Ultra preset that we see a more noticeable dip to 90 FPS. This shows a GPU that is operating well within its comfort zone, with the game's visual complexity not posing a serious challenge to its 504.2 GB/s of memory bandwidth and 158.4 GPixel/s pixel rate.

CPU Role

The Intel Core Ultra X9 388H is a mobile processor with 16 cores and 16 threads, a base clock of 2.10 GHz, and a boost clock of 5.10 GHz. It is based on the Panther Lake architecture and manufactured on Intel's 3 nm process. For a game like Roblox, the CPU is often the primary bottleneck due to its complex physics simulations, scripting, and world generation. The processor's strong single-thread performance is evident in its Cinebench R23 score of 2200.5 points.

Given the high frame rates observed, it is clear the CPU is performing admirably. At 1080p with Low settings, the system hits 364 FPS, which is a staggering number that points to the CPU's ability to feed the GPU with enough data to render frames at an incredible pace. The high boost clock of 5.10 GHz is likely a key factor here, as Roblox's engine typically does not scale well across many cores. The 16-core, 16-thread configuration provides ample multi-threaded power for background tasks and any potential engine optimizations, but the single-thread performance is what shines in this benchmark.

The CPU's average benchmark score of 44466 places it in the 88th percentile of all CPUs, and its nearest rival, the AMD Ryzen 5 7500X3D, is only 0.2% ahead. This suggests that the Ultra X9 388H is at the top tier of processors. However, in the context of Roblox, this power seems almost wasted. The data shows that the system's performance is so high that the CPU is likely not the limiting factor at any resolution or setting. The bottleneck may instead lie within the game's engine itself, which may not be able to utilize the full potential of such a modern, high-end processor.

Measured FPS Breakdown

The measured FPS data provides a detailed look at performance across resolutions and settings.

At 1920x1080, the results are exceptionally high:

• Low: 364 FPS average.
• Medium: 332 FPS average, with a minimum of 282 and a maximum of 381.
• High: 293 FPS average.
• Ultra: 238 FPS average.

At 2560x1440, performance remains stellar:

• Low: 243 FPS average.
• Medium: 221 FPS average, with a minimum of 188 and a maximum of 254.
• High: 196 FPS average.
• Ultra: 159 FPS average.

At 3840x2160, the frame rates start to become more reasonable but are still very high:

• Low: 138 FPS average.
• Medium: 125 FPS average, with a minimum of 106 and a maximum of 144.
• High: 111 FPS average.
• Ultra: 90 FPS average.

The data shows a clear and consistent hierarchy: Lower settings yield higher frame rates at every resolution. The delta between Low and Ultra is significant. At 1080p, the gap is 126 FPS (364 vs. 238), which represents a 35% performance increase when dropping to Low. This gap narrows to 84 FPS at 1440p (243 vs. 159) and 48 FPS at 4K (138 vs. 90). This trend indicates that as resolution increases, the GPU becomes more of a limiting factor, reducing the relative impact of the settings preset.

The Medium preset is the only one with min and max FPS data, providing insight into frame time consistency. At 1080p, the minimum of 282 FPS is still far above the 144 Hz refresh rate of many gaming monitors. Even at 4K, the minimum of 106 FPS ensures a smooth experience on a standard 60 Hz display. This data suggests that even with potential frame drops, the system will not dip below playable thresholds.

Resolution Scaling

The scaling from 1080p to 4K is telling about the system's balance. At Low settings, the average FPS drops from 364 to 138, a 62% decrease. At Medium, it drops from 332 to 125, a 62.3% decrease. At High, it drops from 293 to 111, a 62.1% decrease. At Ultra, it drops from 238 to 90, a 62.2% decrease. The consistency of this percentage drop across all settings is remarkable. It suggests that the performance scaling is primarily driven by the resolution's pixel count, which quadruples from 1080p to 4K. The GPU is having to render four times as many pixels, and the frame rate drops by roughly 62% across the board.

This pattern indicates that the GPU is the primary limiting factor when moving to higher resolutions. The CPU is capable of maintaining its end of the bargain, as the frame rate drop is directly proportional to the increased GPU workload. If the CPU were the bottleneck, we would expect to see a smaller percentage drop at higher resolutions, as the GPU would be waiting on the CPU. Instead, the consistent drop points to a system where the GPU is being progressively more saturated. However, even at 4K Ultra, the 90 FPS average confirms the RTX 4070's power. The data suggests that this component combination is well-balanced for high-resolution gaming, though it is clear that Roblox's engine does not present a heavy load to the hardware.

Settings Recommendations

Based on the measured data, the Medium preset offers the most compelling combination of performance and visual fidelity. It is the only preset with min/max FPS data, which allows for a more complete analysis of frame time stability. At 1920x1080, it delivers a 332 FPS average with a minimum of 282, ensuring an incredibly smooth experience on any high-refresh-rate monitor. At 2560x1440, the 221 FPS average with an 188 FPS minimum is still exceptional for competitive play. Even at 4K, the 125 FPS average and 106 FPS minimum guarantee a fluid experience on high-end displays.

While the Low preset offers higher average frame rates, the gains are marginal in absolute terms. The jump from Medium to Low at 1080p is only 32 FPS (332 to 364), which is a 9.6% increase. For most users, this difference will be imperceptible. The High preset offers a more demanding visual experience but at a cost of 39 FPS compared to Medium at 1080p (293 vs. 332). The Ultra preset, while visually the most impressive, sees a significant drop to 238 FPS at 1080p and 90 FPS at 4K. Given that Medium provides a high minimum FPS across all resolutions, it is the safest and most performance-consistent choice. It offers a balance that avoids the potential for frame drops while still providing a visually rich experience.

How This Combo Ranks

The Intel Core Ultra X9 388H + NVIDIA GeForce RTX 4070 combination ranks 1591 out of 3010 tested combos in Roblox. This places it in the 53rd percentile, which is an unexpectedly low ranking for such high-end hardware. The CPU ranks in the 88th percentile among all CPUs, and the GPU ranks in the 81st percentile. Based on these individual component rankings, one might expect the combo to rank much higher in the game.

The median ranking suggests that a significant number of other tested combinations achieve similar or higher frame rates. This is likely due to Roblox's engine being the limiting factor. The game's performance ceiling may be reached by less powerful hardware, meaning that the extra power of this combo does not translate to a proportionally higher rank. The combo's rank is not a reflection of poor performance, but rather a reflection of the game's scalability. The data shows that this system is capable of pushing Roblox to its limits and beyond, but it also suggests that for this specific title, a less powerful and potentially more cost-effective setup could provide a nearly identical experience. The high frame rates measured are evidence of the hardware's capability, but the rank indicates that Roblox does not require such a powerful combination to run at its best.
