Roblox

Roblox is a sandbox title whose performance is heavily dictated by single-threaded CPU throughput and raw GPU fill rate. The measured data for the Intel Core Ultra X7 368H paired with the NVIDIA GeForce RTX 5080 shows a system that is overwhelmingly capable of high refresh-rate play at every resolution tested, with the primary bottleneck shifting from the GPU at 4K to the CPU at 1080p. This combination ranks in the 74th percentile of all tested combos in this database, placing it in the upper quartile but not at the absolute top, indicating that while the hardware is potent, there are faster configurations available for this specific title.

Settings Recommendations

The measured frame rates across all settings presets at every resolution indicate that the Ultra preset is the only setting that challenges this hardware, while High, Medium, and Low all provide exceptional headroom. At 1920x1080, the Ultra preset delivers an average of 323 FPS, which is still remarkably fluid, but the step down to High yields a substantial 23% increase to 398 FPS. The data shows that the jump from High to Ultra costs roughly 75 FPS at 1080p, suggesting that the Ultra preset introduces rendering features that disproportionately tax the GPU. For competitive play or maximum smoothness, the High preset is the optimal choice, as it maintains a 398 FPS average at 1080p while eliminating the visual overhead that brings the Ultra preset down.

At 2560x1440, the same pattern emerges. The Ultra preset produces 216 FPS, while High delivers 266 FPS, a 23% improvement that mirrors the 1080p delta. The Medium preset sits between these at 301 FPS, which is only 13% faster than High but 39% faster than Ultra. Given that the game is a sandbox title where visual fidelity is secondary to gameplay fluidity, the High preset provides the best balance of image quality and performance. The 1440p High result of 266 FPS is sufficiently above the 240Hz refresh rate threshold that most high-end monitors support, making it the recommended preset for this resolution.

At 3840x2160, the situation becomes more nuanced. The Ultra preset drops to 122 FPS, which is still playable but begins to approach the lower limits of what is acceptable for fast-paced action. High at 4K produces 150 FPS, which is a 23% improvement over Ultra and remains comfortably above 144Hz. Medium at 4K reaches 170 FPS, and Low hits 187 FPS. The scaling from Ultra to High at 4K is the same 23% improvement seen at lower resolutions, confirming that the Ultra preset imposes a consistent rendering cost regardless of resolution. For 4K users, the High preset is the clear recommendation, as it maintains a 150 FPS average that exceeds the refresh rate of most 4K displays while preserving visual quality that is nearly indistinguishable from Ultra in a sandbox environment. The Medium preset offers a 13% gain over High to reach 170 FPS, which may be preferable for users with 4K 240Hz panels, but the data suggests that High is the sweet spot for the majority of use cases.

CPU Role

The Intel Core Ultra X7 368H is a 16-core, 16-thread processor based on the Panther Lake architecture, with a base clock of 2.00 GHz and a boost clock of 5.00 GHz. The benchmark data shows a single-thread score of 4005 in Passmark, which places it in the 87th percentile of all CPUs, and a Cinebench R23 single-core score of 3984. These single-thread metrics are critical for Roblox, as the game's physics and scripting engine are primarily single-threaded. The multi-core performance is equally robust, with a Cinebench R23 multi-core score of 28221 and a Passmark multithread score of 32956, but these are less relevant for a game that does not scale across many cores.

The relationship between the CPU and the measured FPS is most evident at 1080p where the GPU is not the limiting factor. At 1920x1080 with Low settings, the system achieves 495 FPS, which is the highest measured result in the entire dataset. This figure is constrained by the CPU's single-thread throughput, as the RTX 5080 is capable of far higher frame rates. The fact that the 1080p Low result is only 24% higher than the 1080p High result (495 vs 398 FPS) suggests that the CPU is beginning to saturate even with a 5.00 GHz boost clock. The processor's 18 MB of shared L3 cache and 2.5 MB per-core L2 cache provide sufficient memory bandwidth for the game's data structures, but the fundamental single-thread limit is the binding constraint at this resolution.

The CPU's performance relative to its nearest rivals is tightly clustered. The Intel Core 7 253PE scores 40557 in average benchmark, which is only 0.1% higher than the 368H's 40518 average. The AMD Ryzen 9 7940H is 0.2% faster, and the Intel Xeon 6507P is also 0.2% faster. This indicates that the 368H is essentially tied with its direct competitors in general compute, but the 5.00 GHz boost clock gives it a slight edge in the single-thread workloads that Roblox depends on. The data does not show any scenario where the CPU becomes the bottleneck at 1440p or 4K, as the FPS scaling from 1080p to 1440p is consistent with GPU-bound behavior.

GPU Role

The NVIDIA GeForce RTX 5080 is a Blackwell 2.0 architecture GPU with 10752 shading units, 336 texture mapping units, and 112 raster output pipelines. It operates at a base clock of 2295 MHz with a boost clock of 2617 MHz, and is equipped with 16 GB of GDDR7 memory on a 256-bit bus, providing a memory bandwidth of 960.0 GB/s. The GPU's raw compute capability is substantial, with an FP32 throughput of 56.28 TFLOPS, which is more than sufficient for Roblox's relatively simple shader workloads. The Passmark G3D score of 36565 places it in the 87th percentile of all GPUs, and its average benchmark score of 56083 is only 0.7% higher than the AMD Radeon RX 6750 GRE 12 GB, its closest rival.

The GPU's role in this pairing becomes dominant at higher resolutions. At 3840x2160 with Ultra settings, the system produces 122 FPS, which is exactly one-third of the 1080p Low result of 495 FPS. This scaling demonstrates that the GPU is fully engaged at 4K, as the frame rate drops proportionally with the increase in pixel count. The 16 GB of VRAM is never a limiting factor in Roblox, as the game's texture memory requirements are modest, but the 960.0 GB/s bandwidth ensures that the GPU can feed its 112 ROPs efficiently at all tested settings. The pixel rate of 293.1 GPixel/s and texture rate of 879.3 GTexel/s are more than adequate for the game's visual effects, which are primarily fill-rate bound rather than geometry bound.

The GPU's performance at 1440p Ultra (216 FPS) versus 4K Ultra (122 FPS) shows a 44% reduction, which is slightly less than the theoretical 56% reduction from pixel count alone (2.25x fewer pixels at 1440p). This indicates that the GPU is not purely pixel-bound at 1440p, and that the CPU is starting to contribute to the frame time at this resolution. The RTX 5080's boost clock of 2617 MHz is high for a mobile GPU, but the data suggests that the card is running at its full potential in this system, as there are no signs of thermal throttling or power limiting in the measured results.

How This Combo Ranks

The combination of the Intel Core Ultra X7 368H and the NVIDIA GeForce RTX 5080 achieves a rank of 787 out of 3010 tested combos in Roblox. This places it in the 74th percentile of all configurations, meaning that 26% of tested combos perform better. The rank is somewhat surprising given the individual hardware's 87th percentile standings for both CPU and GPU, suggesting that Roblox's specific workload does not scale as well with this hardware as it does with other configurations. The gap between the CPU's rank (87th percentile) and the combo's rank (74th percentile) indicates that other factors, such as memory latency or platform-specific optimizations, may be limiting performance in this title.

The combo's rank relative to the CPU's nearest rivals is not directly measured, but the CPU's average benchmark score of 40518 is nearly identical to the Intel Core 7 253PE (40557, -0.1% delta), the Intel Core 5 223PE (40585, -0.2% delta), the AMD Ryzen 9 7940H (40431, +0.2% delta), and the Intel Xeon 6507P (40426, +0.2% delta). This tight clustering means that swapping the CPU for any of these alternatives would likely produce a negligible change in Roblox performance. Similarly, the GPU's average benchmark score of 56083 is within 2.3% of its nearest rivals, with the AMD Radeon RX 9070 GRE being 2.2% faster and the AMD Radeon Pro W5700X being 2.3% slower. The combo's 74th percentile rank is therefore a reflection of the overall hardware tier, not a specific pairing deficiency.

The fact that this combo ranks in the upper quartile but not the top decile suggests that Roblox favors configurations with even higher single-thread performance or lower memory latency. The 16-core CPU with 16 threads (no hyperthreading) may be at a slight disadvantage compared to CPUs with higher per-core IPC, even though its 5.00 GHz boost clock is competitive. The RTX 5080's massive compute resources are underutilized in Roblox, as the game's rendering complexity does not leverage the GPU's full architectural capabilities. The data shows that the combo is more than capable of delivering excellent frame rates, but it is not the optimal pairing for this specific game.

Resolution Scaling

The measured FPS data reveals a consistent scaling pattern as resolution increases. At High settings, the system achieves 398 FPS at 1080p, 266 FPS at 1440p, and 150 FPS at 4K. This represents a 33% drop from 1080p to 1440p, and a 44% drop from 1440p to 4K. The total drop from 1080p to 4K is 62%, which is close to the theoretical 56% reduction in pixel count (1920x1080 = 2.07 million pixels; 3840x2160 = 8.29 million pixels, a 4x increase). The fact that the FPS drop is larger than the pixel count increase (62% vs 56% expected improvement) indicates that the system is not purely GPU-bound at 1080p, and that the CPU is adding a fixed overhead that becomes less significant at higher resolutions.

At Low settings, the scaling is more pronounced: 495 FPS at 1080p, 330 FPS at 1440p, and 187 FPS at 4K. The drop from 1080p to 1440p is 33%, and from 1440p to 4K is 43%. The total drop from 1080p to 4K is 62%, which is identical to the High setting drop. This consistency suggests that the CPU's contribution is constant regardless of settings, and that the GPU's rendering cost scales linearly with pixel count. At Medium settings, the system produces 450 FPS at 1080p, 301 FPS at 1440p, and 170 FPS at 4K, with drops of 33% and 44% respectively.

The Ultra preset shows the same scaling pattern, with 323 FPS at 1080p, 216 FPS at 1440p, and 122 FPS at 4K. The drop from 1080p to 1440p is 33%, and from 1440p to 4K is 44%. The consistency of these percentages across all settings presets indicates that the limiting component is the GPU at all resolutions above 1080p, while the CPU is the primary constraint at 1080p. The fact that the 1080p Low result (495 FPS) is only 24% higher than the 1080p High result (398 FPS) confirms that the CPU is approaching its maximum frame rate output at 1080p, regardless of the GPU's capability.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. The Low preset produces an average of 495 FPS, which is the fastest measured result in the entire dataset. The Medium preset averages 450 FPS with a minimum of 383 FPS and a maximum of 518 FPS, showing a 30% variance between minimum and maximum frame times. The High preset averages 398 FPS, and the Ultra preset averages 323 FPS. The spread from Low to Ultra at 1080p is 172 FPS, or 35% of the Low result, indicating that the Ultra preset imposes a significant rendering cost that is not present in the lower presets.

At 2560x1440, the frame rates remain exceptionally high. The Low preset averages 330 FPS, the Medium preset averages 301 FPS with a minimum of 256 FPS and a maximum of 346 FPS, and the High preset averages 266 FPS. The Ultra preset drops to 216 FPS. The spread from Low to Ultra at 1440p is 114 FPS, or 35% of the Low result, which is identical to the 1080p spread percentage. This indicates that the relative cost of the Ultra preset is consistent across resolutions, further confirming that the GPU's rendering load scales uniformly.

At 3840x2160, the frame rates are lower but still highly playable. The Low preset averages 187 FPS, the Medium preset averages 170 FPS with a minimum of 145 FPS and a maximum of 196 FPS, and the High preset averages 150 FPS. The Ultra preset produces 122 FPS, which is the only measured result below the 144Hz threshold. The spread from Low to Ultra at 4K is 65 FPS, or 35% of the Low result, maintaining the same 35% ratio seen at lower resolutions. The Medium preset's minimum of 145 FPS at 4K indicates that even in the most demanding scenes, the system stays above 144Hz at Medium settings, making it a viable option for high-refresh-rate 4K displays.
