Roblox

The Intel Core i5-9400 and NVIDIA GeForce RTX 4070 SUPER combination produces exceptionally high frame rates in Roblox, with the data showing this pairing ranks 335th out of 1800 tested combos. The i5-9400 is a 6-core, 6-thread processor based on the Coffee Lake architecture, with a base clock of 2.90 GHz and a boost clock of 4.10 GHz. Its 9 MB of shared L3 cache and dual-channel DDR4 memory support at 42.7 GB/s provide adequate bandwidth for Roblox’s sandbox workloads, though the CPU’s 50th percentile ranking among all processors suggests it is a mid-pack performer. In contrast, the RTX 4070 SUPER sits at the 84th percentile among all GPUs, with 7168 shading units and 12 GB of GDDR6X memory on a 192-bit bus delivering 504.2 GB/s of bandwidth. This disparity in relative strength is visible in the measured results: the GPU is rarely the limiting factor, and the CPU’s six threads become the primary constraint at lower resolutions where frame rates exceed 500 FPS.

The benchmark data reveals that the i5-9400’s single-thread performance, as indicated by a Cinebench R23 single-core score of 1125, is sufficient to drive Roblox’s physics and scripting at high speeds. However, the processor’s six threads without hyper-threading mean that heavily populated servers or complex user-generated content can cause frame pacing inconsistencies, even if average FPS remains high. The 65 W TDP and PCIe Gen 3 lanes (16 from the CPU) do not bottleneck the RTX 4070 SUPER in this title, as Roblox is not bandwidth-sensitive. The measured scores show that at 1080p, the combination is so fast that the CPU’s 4.10 GHz boost clock becomes the ceiling, with the GPU often waiting on the processor to submit draw calls. At 4K, the balance shifts, and the RTX 4070 SUPER’s raw throughput (35.48 TFLOPS FP32) begins to assert itself, yet the i5-9400 still keeps average FPS above 139.9 in the most demanding preset tested.

FAQ

Q: How does the i5-9400 compare to its nearest rivals in synthetic benchmarks?

A: The i5-9400’s average benchmark score of 2305 is nearly identical to the Intel Core i3-10305 (2300, 0.2% faster) and the Intel Core i3-1125G4 (2299, 0.2% faster). It trails the Intel Core i7-8809G (2319) by 0.6% but leads the Intel Xeon E-2134 (2295) by 0.4%. These deltas are negligible, meaning the CPU is statistically tied with these alternatives.

Q: What is the RTX 4070 SUPER’s position relative to other GPUs in the database?

A: The RTX 4070 SUPER has an average benchmark score of 42576, placing it at the 84th percentile of all GPUs. Its closest rival is the NVIDIA RTX A6000 (42653, 0.2% faster), followed by the AMD Radeon RX 7650 GRE (42723, 0.3% faster). It outperforms the AMD Radeon Pro 580X (41991) by 1.4% and the NVIDIA Tesla M40 (41897) by 1.6%, showing it sits in a competitive mid-to-high tier.

Q: Which resolution yields the highest average FPS in Roblox?

A: At 1920x1080 with Low settings, the combo achieves 553.4 FPS average, which is the highest measured result across all tested configurations. The same preset at 2560x1440 drops to 372.8 FPS, and at 3840x2160 it falls to 213.8 FPS, demonstrating that lower resolutions benefit most from the CPU’s boost clock.

Q: How much does the Ultra preset cost in performance compared to Low at each resolution?

A: At 1080p, Ultra (364.6 FPS) is 34.1% slower than Low (553.4 FPS). At 1440p, Ultra (241.6 FPS) is 35.2% slower than Low (372.8 FPS). At 4K, Ultra (139.9 FPS) is 34.6% slower than Low (213.8 FPS). The penalty is consistent across resolutions, indicating that the Ultra preset’s additional effects tax both CPU and GPU proportionally.

Q: Is the RTX 4070 SUPER held back by the i5-9400 in Roblox?

A: Yes, particularly at 1080p. The data shows 553.4 FPS at Low settings, which is near the CPU’s practical limit for a 6-thread part. At 4K, the GPU becomes more relevant, but the i5-9400 still prevents the combo from exceeding 213.8 FPS even on Low, suggesting the CPU is the primary limiter in all tested scenarios.

Q: What is the best measured FPS for a smooth 4K experience?

A: The Medium preset at 3840x2160 delivers 190.6 FPS average, which is the second-highest 4K result behind Low (213.8 FPS). Given Roblox’s visual simplicity, Medium offers a balanced trade-off, but the data shows even Ultra maintains 139.9 FPS, which is well above typical display refresh rates.

How This Combo Ranks

The combination of the Intel Core i5-9400 with the NVIDIA GeForce RTX 4070 SUPER achieves a rank of 335 out of 1800 tested combinations in Roblox, placing it in the top 18.6% of all pairings. This rank reflects the CPU’s 50th percentile standing and the GPU’s 84th percentile, where the latter compensates for the former’s mid-pack performance. The data shows that while the i5-9400 is not a top-tier processor, its six cores are enough to feed the RTX 4070 SUPER in a game that is not heavily multithreaded. The nearest CPU rivals, such as the i3-10305 and i3-1125G4, would likely produce similar ranks due to their near-identical synthetic scores (within 0.2%), but the i5-9400’s slightly higher boost clock gives it a marginal edge in single-threaded workloads.

The combo’s rank is more impressive when considering the GPU’s rivals. The RTX 4070 SUPER outperforms the RTX A6000 by 0.2% and the RX 7650 GRE by 0.3% in aggregate benchmarks, yet in Roblox, the pairing’s rank of 335 suggests that the CPU is the bottleneck. If the same GPU were paired with a stronger processor, the rank would likely improve, but the data does not include such configurations. The measured FPS values are consistently high, with even the worst case (4K Ultra) exceeding 139.9 FPS, which is far above the 60 FPS standard. This indicates that the combo is overqualified for Roblox, and users would see no practical difference between this and a higher-ranked pairing unless they use very high refresh rate monitors at 1080p.

Measured FPS Breakdown

At 1920x1080, the data shows a clear hierarchy across presets. Low settings deliver 553.4 FPS average, Medium drops to 508.7 FPS, High falls to 449.3 FPS, and Ultra bottoms out at 364.6 FPS. The gap between Low and Ultra is 188.8 FPS, or 34.1%, which is substantial but not prohibitive given the absolute numbers. The 1080p results indicate that the CPU is the limiting factor, as the RTX 4070 SUPER could theoretically push higher frame rates, but the i5-9400’s single-thread performance caps the output. The difference between Medium and High is 59.4 FPS, while the difference between High and Ultra is 84.7 FPS, suggesting that the Ultra preset introduces effects (likely shadows and lighting) that disproportionately impact the CPU.

Moving to 2560x1440, the frame rates remain high but show a clearer scaling pattern. Low delivers 372.8 FPS, Medium 343.1 FPS, High 301.3 FPS, and Ultra 241.6 FPS. The percentage drop from Low to Ultra is 35.2%, nearly identical to 1080p, which confirms that the relative cost of Ultra is consistent regardless of resolution. The absolute difference between 1080p and 1440p at the same settings is roughly 180 FPS for Low (553.4 vs 372.8), 165.6 FPS for Medium (508.7 vs 343.1), 148 FPS for High (449.3 vs 301.3), and 123 FPS for Ultra (364.6 vs 241.6). This narrowing gap as settings increase suggests that the GPU is becoming more involved at higher presets.

At 3840x2160, the frame rates drop significantly but remain playable. Low delivers 213.8 FPS, Medium 190.6 FPS, High 172.9 FPS, and Ultra 139.9 FPS. The penalty from Low to Ultra is 34.6%, similar to other resolutions. The 4K results show that the RTX 4070 SUPER’s 12 GB memory buffer and 504.2 GB/s bandwidth are sufficient for Roblox, as even the heaviest preset does not cause a memory bottleneck. The data does not include minimum or maximum FPS values, so the analysis is limited to averages, but the consistency of the scaling across all three resolutions indicates stable performance without thermal or power throttling.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but not linear. At Low settings, the average FPS falls from 553.4 at 1080p to 372.8 at 1440p (a 32.6% decrease) and then to 213.8 at 4K (a 42.6% decrease from 1440p). The total drop from 1080p to 4K is 339.6 FPS, or 61.4%. At Medium settings, the progression is 508.7 to 343.1 (32.5% drop) to 190.6 (44.4% drop from 1440p), with a total decrease of 318.1 FPS (62.5%). For High settings, the numbers are 449.3 to 301.3 (32.9% drop) to 172.9 (42.6% drop), totaling 276.4 FPS (61.5%). Ultra shows 364.6 to 241.6 (33.7% drop) to 139.9 (42.1% drop), for a total of 224.7 FPS (61.6%).

The consistency of the percentage drops (roughly 32-34% from 1080p to 1440p, and 42-44% from 1440p to 4K) indicates that the limiting component is the same across resolutions. At 1080p, the i5-9400 is the bottleneck, as evinced by the very high FPS that exceed the CPU’s capability to process game logic. As resolution increases, the GPU workload grows, but the RTX 4070 SUPER has enough headroom that the CPU remains the primary constraint even at 4K. The fact that 4K Low (213.8 FPS) is still nearly triple the 60 FPS target suggests that the GPU is never fully saturated. The data shows that the i5-9400’s 2.90 GHz base clock and 4.10 GHz boost clock are the limiting factors, as Roblox’s single-threaded nature means the 6 cores are often underutilized, with one or two threads carrying the load.

Settings Recommendations

Based on the measured FPS data, the Medium preset at 2560x1440 offers the best balance for most users, delivering 343.1 FPS average. This is 70.7% higher than the Ultra preset at the same resolution (241.6 FPS) and still 29.7 FPS above the High preset (301.3 FPS). The Medium preset at 1440p provides a smooth experience for high refresh rate monitors (up to 240 Hz) without the unnecessary visual overhead of Ultra, which costs 29.6% performance for marginal visual gains in a sandbox game. For 4K displays, the Medium preset at 190.6 FPS is recommended, as it stays above 144 Hz refresh rates while avoiding the 23.5% penalty of Ultra (139.9 FPS) compared to High (172.9 FPS).

At 1080p, the data shows that even Ultra (364.6 FPS) exceeds the refresh rate of virtually all monitors, so users with 1080p displays should select Ultra for the best visual quality without sacrificing fluidity. The Low preset at 553.4 FPS is only useful for competitive play where every millisecond matters, but the difference from Medium (508.7 FPS) is negligible in practice. The High preset at 449.3 FPS sits in a middle ground, but the 13.1% difference between High and Ultra (449.3 vs 364.6) is worth the visual upgrade for most players. The data does not include minimum FPS, so users with VRR displays should be cautious, but the high averages indicate that frame drops are unlikely to be noticeable. Overall, the RTX 4070 SUPER’s 84th percentile ranking ensures that the GPU will not be a limiting factor at any preset, making the CPU the sole consideration for settings selection—and the i5-9400’s performance is sufficient for all but the most extreme 1080p esports scenarios.
