Roblox

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3070 delivers an exceptionally high-performance experience in Roblox, a game that is both CPU-light and highly scalable. The measured data shows that this combination is not the limiting factor at any resolution, with average frame rates ranging from 102 FPS at 4K Ultra to 413 FPS at 1080p Low. The bottleneck shifts from the GPU at higher resolutions to the CPU at lower resolutions, but even in the most demanding CPU scenario, the i5-10400F’s six cores and 12 threads prove sufficient to keep frame rates well above display refresh rates.

Resolution Scaling

The measured FPS data shows a clear pattern of performance scaling from 1080p to 4K. At 1920x1080, the average frame rate across the four settings ranges from 270 FPS at Ultra to 413 FPS at Low. Stepping up to 2560x1440, the averages drop to between 180 FPS at Ultra and 276 FPS at Low. At 3840x2160, the averages fall further to between 102 FPS at Ultra and 156 FPS at Low. This scaling is not linear, indicating that the rendering load on the GPU increases disproportionately as resolution rises.

The percentage drop from 1080p to 4K is substantial. For the High preset, the average frame rate falls from 332 FPS at 1080p to 222 FPS at 1440p, and then to 125 FPS at 4K. This represents a 62% reduction from 1080p to 4K. The Low preset drops from 413 FPS to 276 FPS, then to 156 FPS, a 62% reduction as well. The Ultra preset falls from 270 FPS to 180 FPS, then to 102 FPS, a 62% reduction. The consistency of this drop across settings suggests that the limiting component is the GPU, as it is responsible for rendering the additional pixels.

At 1080p, the frame rates are exceptionally high, with the Low preset reaching 413 FPS and Medium reaching 376 FPS. This indicates that the CPU is capable of feeding the GPU with enough data to maintain these frame rates. The high performance at 1080p also suggests that the game is not heavily single-thread bound, as the i5-10400F’s single-core performance, while not elite, is sufficient to keep up. The data shows that the frame rate ceiling at 1080p is not CPU-limited, as the difference between Low and Ultra presets is only 143 FPS, which is a moderate drop compared to the 257 FPS difference between Low and Ultra at 4K.

The scaling from 1440p to 4K is more pronounced than from 1080p to 1440p, indicating that the GPU is working harder at higher resolutions. The RTX 3070 has 8 GB of GDDR6 memory on a 256-bit bus, with a bandwidth of 448.0 GB/s, which is ample for Roblox’s modest texture requirements. The data shows that the GPU’s memory bandwidth is not a constraint, as the frame rates remain high even at 4K.

How This Combo Ranks

According to the comboRankInGame data, this combination of the Intel Core i5-10400F and NVIDIA GeForce RTX 3070 ranks 1596th out of 3711 tested combinations in Roblox. This places it in the 43rd percentile of all tested combos, meaning it outperforms 57% of the combos tested. While not a top-tier ranking, it is a solid position, considering the game is very old and has low system requirements.

The ranking indicates that the combo is not the absolute best for the game, but it is far from the bottom. The combination of a mid-range CPU and a high-end GPU yields a balanced performance that is well-suited for Roblox’s engine. The combo’s rank is influenced by the fact that many combos with more powerful CPUs or GPUs exist, but the i5-10400F and RTX 3070 together provide a frame rate advantage that many other combos cannot match.

The data shows that the combo’s rank is not as high as the individual component percentiles would suggest. The CPU has a percentile of 68% among all CPUs, and the GPU has a percentile of 61% among all GPUs. However, the combo’s rank is in the 57th percentile, which is lower than the average of the two. This suggests that the game does not scale perfectly with the hardware, and that other factors, such as memory bandwidth or driver overhead, may be playing a role. Even so, the combo is capable of delivering high frame rates at all resolutions, which is the ultimate judge of its worth.

CPU Role

The Intel Core i5-10400F is a six-core, twelve-thread processor based on the Comet Lake architecture, manufactured on a 14 nm process. It has a base clock of 2.90 GHz and a boost clock of 4.30 GHz. The CPU’s TDP is 65 watts, which is modest for a desktop processor, but it is sufficient for Roblox’s undemanding CPU requirements. The processor has 12 MB of shared L3 cache, and its memory support is dual-channel DDR4 with a bandwidth of 42.7 GB/s.

In this game, the CPU is not the bottleneck at any resolution. The benchmark results show that the frame rate is consistently high, even at 1080p where the CPU is more likely to be the limiting factor. The i5-10400F’s six cores and 12 threads are more than enough for Roblox, as the game typically uses only a few threads. The single-thread performance is adequate, as evidenced by the 3DMark single-thread score of 688 and the Cinebench R23 single-core score of 1451. These scores are not top-tier, but they are sufficient for a sandbox game like Roblox.

The CPU’s multi-threaded performance is also strong, with a Cinebench R23 multi-core score of 10283 and a Geekbench multi-core score of 6257. This indicates that the processor can handle additional background tasks while gaming, but it is not a major factor in Roblox’s performance. The boost clock of 4.30 GHz ensures that the CPU can quickly respond to the game’s demands, and the 65W TDP means it will not generate excessive heat, allowing for a quiet and cool build.

The data shows that the CPU is a capable pairing for the RTX 3070 in this game. The combo’s performance is not limited by the CPU, as the frame rates are high even at 1080p. The 3DMark 8-thread score of 3929 and the Passmark multi-thread score of 12115 indicate that the CPU can handle the game’s multi-threaded load, but the game does not require heavy multithreading. The i5-10400F’s single-thread performance is the more important factor, and it is sufficient to keep the GPU fed at 1080p.

Measured FPS Breakdown

At 1920x1080, the average frame rates are as follows: Low preset runs at 413 FPS, Medium at 376 FPS with a minimum of 320 FPS and a maximum of 432 FPS, High at 332 FPS, and Ultra at 270 FPS. The 143 FPS difference between Low and Ultra is a notable drop, but even the Ultra preset provides a frame rate that is far above any display refresh rate. The minimum FPS is only recorded for the Medium preset, which is 320 FPS, indicating that this is the only setting where frame times are consistent enough to record.

At 2560x1440, the performance scales down. The Low preset average is 276 FPS, Medium averages 251 FPS with a min of 213 FPS and a max of 289 FPS, High averages 222 FPS, and Ultra averages 180 FPS. The difference between Low and Ultra is 96 FPS, which is less than at 1080p, showing that the GPU is becoming more of a limiting factor. The Medium preset’s minimum of 213 FPS is still high, indicating that frame pacing is consistent.

At 3840x2160, the frame rates are still very high. The Low preset averages 156 FPS, Medium averages 142 FPS with a minimum of 121 FPS and a maximum of 163 FPS, High averages 125 FPS, and Ultra averages 102 FPS. The difference between Low and Ultra is 54 FPS, which is the smallest gap of any resolution, showing that the GPU is the primary bottleneck. The medium preset’s minimum of 121 FPS is still well above the 60 FPS threshold, and the maximum of 163 FPS indicates that the frame rate can spike even at 4K.

The data shows that the Medium preset provides the best balance of quality and performance, as it is the only preset with full min/max data at all resolutions. The minimum FPS for Medium is 320 FPS at 1080p, 213 FPS at 1440p, and 121 FPS at 4K, all of which are above the refresh rate of any standard display. The High and Ultra presets do not have min/max data, but their averages are still high, with the Ultra preset’s 102 FPS at 4K being the only instance where the average drops below 120 FPS.

GPU Role

The NVIDIA GeForce RTX 3070 is a high-end GPU based on the Ampere architecture, manufactured on an 8 nm process. It features 5888 shading units, 184 texture mapping units, and 96 raster output units. The GPU has 46 RT cores and 184 tensor cores, which are for ray tracing and AI tasks, but Roblox does not use these features. The base clock is 1500 MHz and the boost clock is 1725 MHz, with a memory clock of 1750 MHz (14 Gbps effective) for the 8 GB of GDDR6 memory on a 256-bit bus.

The GPU’s memory bandwidth is 448.0 GB/s, which is ample for Roblox’s textures. The VRAM is 8 GB, which is not a limitation at any resolution. The GPU’s performance is highlighted by its 3DMark Steel Nomad score of 3162 and its Passmark G3D score of 22214, which are strong scores for a GPU that is now end-of-life. The GPU’s percentile is 61% among all GPUs, with its nearest rivals being the RX 7600 XT (with a delta of 0.7%), GTX 690 (1% delta), HD 7970M (1.1%), and Tesla K40c (-1.5%), showing that it is positioned close to these cards in average score.

In Roblox, the GPU is the primary component that determines the frame rate at higher resolutions. The data shows that at 1080p, the frame rates are high enough to be CPU-limited, but at 1440p and 4K, the GPU becomes the bottleneck. The RTX 3070’s power is evident at 4K, where it still manages to an average of 125 FPS at High settings. The GPU’s compute power, as shown by its FP32 performance of 20.31 TFLOPS, is more than enough for this game.

The GPU’s memory capacity is not a concern, as the game’s textures are not large, but the bandwidth may be the limiting factor at 4K. However, the high frame rates at 4K show that the GPU’s bandwidth is sufficient. The GPU’s performance is such that it can handle the game at high frame rates at all settings, but the Ultra preset at 4K is the only one that drops below a 120 FPS average.

Settings Recommendations

The measured data shows that the Medium preset is the sweet spot for this combo. It is the only preset that has full min/max data, indicating that it is the most well-optimized setting. At 1080p, the Medium preset averages 376 FPS with a minimum of 320 FPS, which is far above any display’s refresh rate. At 1440p, the Medium preset averages 251 FPS with a minimum of 213 FPS, also high. At 4K, the Medium preset averages 142 FPS with a minimum of 121 FPS, which is still above the standard 60 FPS refresh.

The Ultra preset is not recommended if you have a high refresh rate display at 4K, as it averages 102 FPS, which is below a 144 Hz display’s refresh rate. The High preset is a compromise, but the Medium preset provides a better frame rate without a significant visual quality difference. The Low preset is not needed, as the Medium preset provides a higher frame rate than the Low preset at all resolutions, which is unusual.

If you have a 1080p or 1440p display, the Ultra preset is viable, as it averages 270 FPS at 1080p and 180 FPS at 1440p. The High preset is also good, with the 332 FPS at 1080p and 222 FPS at 1440p. The choice between High and Ultra is a visual quality trade-off, but the frame rates are so high that either is a good choice. The Low preset is not recommended, as it does not provide a meaningful frame rate advantage over Medium, and the visual quality is significantly worse.

In summary, the Medium preset is the best balanced setting for this combo, as it maintains a high average frame rate and has consistent frame times. For 4K displays, the Medium is the best choice, while for 1080p and 1440p, the Ultra preset is also a strong option. The data shows that this combo is capable of a great experience in Roblox, and the settings can be adjusted to match the display’s refresh rate.
