Roblox

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 2070 SUPER combination delivers exceptionally high frame rates in Roblox, a sandbox title that is far more forgiving on hardware than most modern releases. The data shows a system capable of triple-digit frame rates even at 4K, with performance scaling that clearly indicates where the bottleneck lies as resolution and settings increase.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor built on the Zen 4 architecture (codenamed Phoenix) and fabricated on TSMC's 4 nm process. It operates with a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 65 W TDP. This processor sits in a peculiar spot within the 8000 series, featuring 16 MB of shared L3 cache and 1 MB of L2 per core, with 64 KB of L1 per core. It supports DDR5 memory on a dual-channel bus with a total bandwidth of 83.2 GB/s, and connects via PCIe Gen 4 with 20 lanes.

In Roblox, the CPU's role is often more pronounced at lower resolutions where the GPU is not saturated. The measured results show that at 1080p Low, the combo reaches 339 FPS, which is the highest average recorded across all tested configurations. This suggests that the Ryzen 5 8400F is capable of feeding the GPU with frames efficiently, but the data also reveals that the processor's single-threaded performance is a limiting factor at the highest refresh rates. Its 3DMark single-thread score of 951 and PassMark single-thread score of 3685 are respectable for a desktop part, but the gap between 1080p Low (339 FPS) and 1080p Ultra (221 FPS) is nearly identical to the gap seen at 4K resolutions, indicating that the CPU is not the primary constraint when settings are increased.

The processor's multi-threaded capabilities are strong for this workload, with a Cinebench R23 multi-core score of 20851 and a PassMark multithread score of 24389. This puts it in the 77th percentile of all CPUs, with its nearest rival being the AMD Ryzen 5 7500F, which has an average score of 24964 and a deltaPct of 0.2 — essentially a dead heat. The Intel Core i7-13620H trails by 0.4 percent, while the AMD EPYC 9474F is 0.4 percent ahead. This level of multi-threaded performance is more than sufficient for Roblox, which is not heavily threaded, but it does ensure that background tasks and game logic do not cause frame drops.

The data suggests that at 1080p, the CPU is doing the heavy lifting to push frame rates above 300 FPS. At 1080p Medium, the average is 308 FPS with a minimum of 262 FPS, and at High, it drops to 272 FPS. These numbers are all well above any standard monitor's refresh rate, meaning the CPU is delivering far more frames than the display can show. The real question is how the processor's performance scales with settings, and the answer is that it handles the added load gracefully, with no dramatic falloff.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 2070 SUPER is based on the TU104 chip, manufactured on TSMC's 12 nm process with 13,600 million transistors. It features 8 GB of GDDR6 memory on a 256-bit bus, providing 448.0 GB/s of bandwidth. The GPU operates at a base clock of 1605 MHz and a boost clock of 1770 MHz, with memory running at 1750 MHz (14 Gbps effective). It has 2560 shading units, 160 TMUs, and 64 ROPs, along with 40 RT cores and 320 tensor cores, delivering 9.062 TFLOPS of FP32 performance.

In Roblox, the GPU's role becomes increasingly important as resolution and settings rise. The measured data shows that at 4K Ultra, the combo drops to 83 FPS, which is the lowest average recorded. This indicates that the RTX 2070 SUPER is the limiting component at the highest settings, as the CPU's performance deficit is not significant enough to cause such a large drop. The GPU's 8 GB VRAM is not a concern in this title, as Roblox is not particularly memory-hungry, but the raw compute power is what matters.

The GPU's benchmark scores show it ranks in the 65th percentile of all GPUs, with an average benchmark score of 20282. Its nearest rivals include the NVIDIA Quadro M4000M, which trails by 1 percent, and the NVIDIA GeForce RTX 3070 Mobile, which is 1.2 percent ahead. The Intel Arc B570 and Arc A750 are 1.3 percent and 1.5 percent ahead, respectively. This places the RTX 2070 SUPER in a competitive position, but the data from Roblox shows that it is not a 4K Ultra powerhouse.

At 1080p, the GPU is not the bottleneck. The frame rates at 1080p Ultra (221 FPS) are dramatically higher than at 4K Ultra (83 FPS), which shows that the GPU has ample headroom at lower resolutions. The transition from 1080p to 1440p sees a significant drop, with the 1440p Ultra average falling to 148 FPS, indicating that the GPU is starting to feel the load. The RTX 2070 SUPER's 256-bit memory bus and 448 GB/s bandwidth are sufficient for Roblox's relatively simple textures, but the compute units are stretched at higher settings.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The measured FPS data reveals a clear pattern of scaling across resolutions. At 1080p Low, the combo achieves 339 FPS. Moving to 1440p Low, the average drops to 226 FPS, a reduction of 33 percent. At 4K Low, the average falls to 128 FPS, which is a further 43 percent drop from 1440p and a 62 percent drop from 1080p. This steep decline at the same settings is a strong indicator that the GPU is the primary limiting factor, as the CPU's workload does not change with resolution.

The same pattern holds for Medium settings. At 1080p Medium, the average is 308 FPS, dropping to 206 FPS at 1440p Medium (a 33 percent reduction) and then to 116 FPS at 4K Medium (a 44 percent reduction from 1440p). The minimum FPS at 1080p Medium is 262 FPS, at 1440p Medium it is 175 FPS, and at 4K Medium it is 99 FPS. These minimums show that the frame pacing remains consistent, with no sudden stutters, but the overall performance degrades predictably as pixel count increases.

The High settings show a similar trend. At 1080p High, the average is 272 FPS, dropping to 182 FPS at 1440p High (a 33 percent reduction) and 103 FPS at 4K High (a 43 percent reduction from 1440p). The Ultra settings exhibit the most pronounced scaling, with 1080p Ultra at 221 FPS, 1440p Ultra at 148 FPS (a 33 percent reduction), and 4K Ultra at 83 FPS (a 44 percent reduction from 1440p). The consistency of these percentage drops across all settings strongly suggests that the GPU is the bottleneck, as the relative performance decrease is nearly uniform.

If the CPU were the limiting factor, the frame rates at 1080p would be much closer to those at 4K, since the CPU's workload is identical regardless of resolution. The fact that the 4K averages are less than half of the 1080p averages at every settings level confirms that the RTX 2070 SUPER is the component that determines the performance ceiling in this title. The CPU's role is to ensure that it can feed the GPU, which it does admirably, as evidenced by the high frame rates at lower resolutions.

Settings Recommendations — which preset gives the best experience per the measured rows

Based on the measured FPS data, the Medium preset offers the best balance between visual quality and performance across all resolutions. At 1080p Medium, the combo achieves an average of 308 FPS with a minimum of 262 FPS, which is well above any display's refresh rate and provides a smooth experience with minimal risk of drops. The jump from Low (339 FPS) to Medium (308 FPS) is only a 9 percent reduction, but the visual improvement in a game like Roblox is significant, as Medium adds detail that makes the sandbox environments more immersive.

At 1440p, the Medium preset delivers an average of 206 FPS with a minimum of 175 FPS. This is still exceptionally high and ensures that even the most demanding scenes in Roblox will not cause noticeable stuttering. The High preset at 1440p drops to 182 FPS, which is also playable, but the Medium preset provides a larger safety margin for the minimum frame rate. The Ultra preset at 1440p falls to 148 FPS, which is still smooth, but the gains over Medium are marginal for the added load.

At 4K, the Medium preset is the clear recommendation. The average of 116 FPS with a minimum of 99 FPS is the only 4K configuration that stays above the 100 FPS threshold, and it provides a consistently smooth experience. The High preset at 4K averages 103 FPS, which is close, but the minimum is not recorded, making it a riskier choice. The Ultra preset at 4K drops to 83 FPS, which is still playable but not ideal for a game that benefits from high frame rates. The Low preset at 4K offers 128 FPS, but the visual compromise is substantial.

The data shows that Medium is the sweet spot because it maintains a minimum FPS above 99 at 4K and above 175 at 1440p, which are the critical metrics for avoiding perceptible stutter. The High preset is acceptable if the user prefers slightly better visuals, but the Medium preset's consistency makes it the safer choice. The Ultra preset is not worth the performance cost, as the frame rate drops by more than 30 percent compared to Medium at every resolution.

How This Combo Ranks — use comboRankInGame vs other tested combos

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 2070 SUPER combination ranks 2139 out of 3711 tested combos in Roblox. This places it in the 42nd percentile of all tested configurations, which is notable given the game's age and the hardware's specifications. The rank indicates that while this combo is not at the top of the charts, it is still ahead of a majority of systems that have been benchmarked for this title.

The ranking is influenced by the fact that Roblox is a highly optimized game that can run on a wide range of hardware, meaning that many lower-end components can achieve playable frame rates. The RTX 2070 SUPER's position in the 65th percentile of all GPUs, combined with the Ryzen 5 8400F's 77th percentile ranking, suggests that this combo should perform better than its overall rank indicates. However, the data shows that the GPU is the limiting factor at higher settings, which may explain why the combo does not rank higher.

When compared to other combos in the database, this pairing is competitive, but it is not a top-tier performer. The nearest GPU rivals, such as the Intel Arc B570 and Arc A750, have average benchmark scores that are 1.3 percent and 1.5 percent higher, respectively, which could translate to better Roblox performance if paired with a similarly capable CPU. However, the combo's rank of 2139 out of 3711 means that it outperforms roughly 42 percent of tested systems, which is a reasonable result for a mid-range setup from the previous generation.

The rank also reflects the fact that Roblox is not a demanding title, so even older hardware can achieve high frame rates. The combo's ability to maintain above 60 FPS at 4K Ultra confirms its capabilities, but the rank shows that there are many systems that can do the same or better. The data indicates that this combo is best suited for high-refresh-rate gaming at 1080p or 1440p, where it excels, rather than for 4K enthusiasts who would benefit from a more powerful GPU.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data provides a comprehensive view of the combo's performance across all tested configurations. At 1920x1080, the lowest resolution tested, the combo achieves its highest frame rates. The Low preset delivers an average of 339 FPS, the Medium preset averages 308 FPS with a minimum of 262 FPS and a maximum of 354 FPS, the High preset averages 272 FPS, and the Ultra preset averages 221 FPS. These numbers show that at 1080p, the combo is more than capable of driving any high-refresh-rate monitor, with even the Ultra preset staying well above 200 FPS.

Moving to 2560x1440, the frame rates drop significantly but remain exceptionally high. The Low preset averages 226 FPS, the Medium preset averages 206 FPS with a minimum of 175 FPS and a maximum of 237 FPS, the High preset averages 182 FPS, and the Ultra preset averages 148 FPS. The minimum FPS at Medium is still above the refresh rate of most 1440p monitors, ensuring a smooth experience. The gap between Low and Ultra at 1440p is 78 FPS, which shows that the GPU is being taxed more heavily at this resolution.

At 3840x2160, the combo's performance is more constrained. The Low preset averages 128 FPS, the Medium preset averages 116 FPS with a minimum of 99 FPS and a maximum of 134 FPS, the High preset averages 103 FPS, and the Ultra preset averages 83 FPS. The minimum FPS at Medium is just below 100, which is the first time in the data that the combo dips below that threshold. The Ultra preset at 4K is the only configuration that falls below 90 FPS, indicating that the RTX 2070 SUPER is reaching its limits at this resolution with maximum settings.

The data shows a clear progression: at 1080p, the combo is CPU-limited at Low settings, but the GPU becomes the bottleneck as settings increase. At 4K, the GPU is the definitive bottleneck across all settings, with the frame rates scaling almost linearly with the number of pixels rendered. The exact numbers reveal that the combo delivers a minimum of 99 FPS at 4K Medium, which is the lowest minimum recorded in the entire dataset, while the maximum of 354 FPS at 1080p Medium shows the combo's peak capability. These figures provide a complete picture of what users can expect from this hardware pairing in Roblox.
