Roblox

Roblox is a sandbox title with a long service life, and the measured data for the Intel Core i5-9400 paired with the NVIDIA GeForce RTX 5060 shows a system that delivers extremely high frame rates across all tested configurations. The combination ranks 867th out of 1800 tested combos, placing it in the upper half of the database, though the specific performance characteristics reveal a workload that is heavily influenced by both CPU and GPU depending on the settings and resolution chosen. The RTX 5060, with its 8 GB of GDDR7 memory on a 128-bit bus providing 448.0 GB/s of bandwidth, is clearly capable of pushing this game far beyond standard display refresh rates, while the i5-9400's six cores and six threads at up to 4.10 GHz boost clock appear to be a limiting factor at lower resolutions.

Settings Recommendations

The measured FPS data provides a clear hierarchy for optimizing the experience in Roblox. At 1920x1080, the Low preset delivers an average of 386.7 FPS, which is the highest score recorded for this system. Medium follows closely at 354.0 FPS, and High drops to 309.7 FPS. The Ultra preset, while still impressive at 252.9 FPS, represents a significant 133.8 FPS reduction from Low. Given that the game is a sandbox with frequent user-generated content and physics interactions, the extra headroom from lower presets can be beneficial for maintaining consistency during complex scenes. For competitive or high-refresh-rate play, the Low preset at 1080p is the most effective, as it provides the maximum average frame rate and likely reduces visual effects that could obscure fast-moving objects.

Moving to 2560x1440, the pattern remains similar but with a tighter spread. Low yields 257.3 FPS, Medium 235.1 FPS, and High 206.7 FPS. The Ultra preset drops to 166.0 FPS. At this resolution, the Medium preset offers a strong balance, delivering 235.1 FPS while presumably enabling more visual fidelity than Low. The difference between Low and Medium is 22.2 FPS, which is less pronounced than the 32.7 FPS gap between Medium and High. For users with 1440p displays, Medium appears to be the sweet spot, as it maintains frame rates well above 200 FPS while still providing a richer visual experience than the lowest settings.

At 3840x2160, all presets remain playable, but the performance ceiling is lower. Medium produces 130.3 FPS, High 118.4 FPS, and Low 149.1 FPS. Ultra falls to 96.1 FPS. The data indicates that at 4K, the system becomes more balanced between CPU and GPU loads, as the frame rate differences between presets are less dramatic than at lower resolutions. For a 4K display, the High preset at 118.4 FPS is a solid choice, offering a substantial improvement over Ultra's 96.1 FPS while still looking better than Medium's 130.3 FPS. However, if a user prioritizes maximum smoothness on a 120Hz display, the Medium preset is the safer option, as it stays above 120 FPS on average.

GPU Role

The NVIDIA GeForce RTX 5060 plays a critical role in this system's Roblox performance, particularly at higher resolutions and settings. The GPU is built on the Blackwell 2.0 architecture with a 5 nm process node from TSMC, containing 21,900 million transistors on a 181 mm² die. Its 8 GB of GDDR7 memory operates at an effective speed of 28 Gbps, yielding a bandwidth of 448.0 GB/s across the 128-bit interface. This memory configuration is sufficient for Roblox, which is not a particularly texture-heavy game, but the bandwidth becomes relevant when the resolution increases to 3840x2160 and the render target requires more memory throughput.

The GPU's clock speeds are notable: a base clock of 2280 MHz and a boost clock of 2497 MHz. These clocks, combined with 3840 shading units and 48 ROPs, allow the RTX 5060 to handle the geometry and draw calls typical of user-generated Roblox worlds. The pixel rate of 119.9 GPixel/s and texture rate of 299.6 GTexel/s are more than adequate for this title. The GPU's benchmark scores reflect its capability, with a Passmark G3D score of 20891 and a Geekbench OpenCL score of 120785. Its average benchmark score is 30109, placing it in the 73rd percentile of all GPUs, and it is roughly level with the AMD Radeon RX 7700 XT, which has an average score of 30097.

The data suggests that the GPU is not the primary bottleneck at 1920x1080, where CPU limitations likely cap performance. However, as resolution increases to 2560x1440 and 3840x2160, the GPU's workload grows. At 4K Ultra, the system averages 96.1 FPS, which indicates that the RTX 5060 is being pushed harder. The GPU supports DirectX 12 Ultimate and Vulkan 1.4, both of which are relevant for modern Roblox updates. The 8 GB VRAM is unlikely to be exceeded by Roblox's typical asset sizes, even at 4K, but the memory bandwidth of 448.0 GB/s is the more critical factor for maintaining high frame rates at that resolution.

Measured FPS Breakdown

The measured data provides a complete matrix of performance across four settings presets and three resolutions. At 1920x1080, the Low preset achieves 386.7 FPS, which is the peak performance for this system. Medium follows at 354.0 FPS, High at 309.7 FPS, and Ultra at 252.9 FPS. The scaling from Low to Ultra at 1080p shows a 133.8 FPS drop, indicating that the CPU's single-thread performance, evidenced by its Cinebench R23 single-core score of 1125, becomes a limiting factor as more visual effects are enabled.

At 2560x1440, the frame rates decrease across all presets, but the relative ordering remains consistent. Low produces 257.3 FPS, Medium 235.1 FPS, High 206.7 FPS, and Ultra 166.0 FPS. The difference between Low and Ultra at 1440p is 91.3 FPS, which is less than the 133.8 FPS gap at 1080p, suggesting that the GPU is starting to take on more of the rendering load as the pixel count increases.

At 3840x2160, the frame rates drop further, but the system still delivers smooth gameplay. Low averages 149.1 FPS, Medium 130.3 FPS, High 118.4 FPS, and Ultra 96.1 FPS. The gap between Low and Ultra at 4K narrows to 53 FPS, which is the smallest difference across all resolutions. This indicates that at 4K, the GPU is more consistently the bottleneck, as the absolute frame rates are lower and the settings have a smaller relative impact on performance. The RTX 5060's 19.18 TFLOPS of FP32 compute and 8 GB of memory are being utilized more fully at this resolution, as evidenced by the Passmark G3D score of 20891.

Resolution Scaling

The transition from 1920x1080 to 2560x1440 and then to 3840x2160 reveals how the system's workload shifts between the CPU and GPU. At 1080p Low, the system achieves 386.7 FPS. Moving to 1440p Low, the average drops to 257.3 FPS, a 33.5% decrease. Moving to 4K Low, the average drops to 149.1 FPS, a 42.1% decrease from 1440p and a 61.4% decrease from 1080p. This steep scaling at Low settings indicates that the CPU is likely the primary limiter at 1080p, as the GPU has ample headroom until the pixel count increases significantly.

For the Ultra preset, the scaling is more moderate. At 1080p Ultra, the system hits 252.9 FPS. At 1440p Ultra, it drops to 166.0 FPS, a 34.4% reduction. At 4K Ultra, it falls to 96.1 FPS, a 42.1% reduction from 1440p. The fact that the Ultra preset's percentage drop from 1080p to 1440p (34.4%) is similar to the Low preset's drop (33.5%) suggests that the CPU is still a factor even with more demanding graphics settings. However, the absolute frame rates at 4K Ultra (96.1 FPS) versus 4K Low (149.1 FPS) show that the GPU's load is substantially higher when all effects are enabled.

The scaling data points to a system where the Intel Core i5-9400, with its 6 cores and 6 threads and a Cinebench R23 multicore score of 7969, keeps up well at 1080p but begins to show its age as the resolution increases. The RTX 5060, on the other hand, scales more predictably with resolution, as evidenced by its performance at 4K where it still manages to exceed 96 FPS on Ultra. The result is that users seeking the highest frame rates should stick to 1080p, while those with 4K displays can still enjoy a playable experience, albeit with a trade-off in settings to stay above 100 FPS.
