Roblox

The Intel Core i5-10400F paired with the AMD Radeon RX 6600 delivers exceptionally high frame rates in Roblox, with the data showing that the combination is rarely constrained by hardware at standard resolutions. Across all tested settings, the average frame rate never drops below 67.5 FPS, which occurs only at 4K with Ultra settings. The benchmark results indicate that this pairing is far more capable than Roblox’s typical demands, as even the most demanding configuration tested remains comfortably playable. The performance scaling between resolutions reveals that the GPU becomes the primary limiting factor as pixel count increases, while at 1080p the CPU’s single-thread performance is sufficient to drive very high frame rates.

Resolution Scaling

The measured FPS data shows a clear and expected pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate drops from 224.4 FPS at 1080p to 152.2 FPS at 1440p, a reduction of approximately 32%. Moving from 1440p to 2160p, the frame rate falls further to 82.4 FPS, which represents a 46% drop. This steep decline at 4K strongly indicates that the Radeon RX 6600’s rendering throughput is the bottleneck at higher resolutions, as the pixel count quadruples from 1080p to 4K while the frame rate does not scale proportionally.

The scaling behavior differs noticeably between settings presets. At Low settings, the 1080p result of 282.7 FPS drops to 190.4 FPS at 1440p and then to 103.8 FPS at 4K. The relative drop from 1080p to 4K is about 63%, which is less severe than the 70% drop seen at Ultra settings, where frame rates go from 182.2 FPS at 1080p down to 67.5 FPS at 4K. This pattern suggests that at Ultra settings, the additional graphical workload compounds the resolution penalty, placing more stress on the GPU’s compute units and memory bandwidth.

At 1080p, the frame rates across all settings are extraordinarily high, ranging from 182.2 FPS at Ultra to 282.7 FPS at Low. These numbers imply that the i5-10400F, with its boost clock of 4.30 GHz and 12 MB of shared L3 cache, is capable of feeding the GPU adequately at this resolution. The spread between Low and Ultra at 1080p is about 100 FPS, which shows that the GPU is still doing meaningful work even at lower settings. However, the fact that even the highest setting exceeds 180 FPS suggests that the combo is not CPU-limited in a problematic way; instead, the GPU has headroom to spare.

FAQ

Q: What is the best resolution to use for competitive play with this combo?

A: At 1920x1080, the data shows the highest frame rates across all settings, with Low achieving 282.7 FPS and Ultra still reaching 182.2 FPS. This resolution provides the maximum performance margin, making it the optimal choice for high-refresh-rate monitors.

Q: Can this combo handle 4K gaming in Roblox?

A: Yes, but with caveats. At 3840x2160, the average frame rates range from 103.8 FPS at Low to 67.5 FPS at Ultra. While all results are above 60 FPS, the Ultra preset is notably less smooth compared to lower settings, indicating that the RX 6600 is nearing its limits at 4K.

Q: How does the Ultra preset compare to High at 1440p?

A: The data shows a significant drop when moving from High to Ultra at 2560x1440, with frame rates falling from 152.2 FPS to 123.4 FPS. This 19% reduction suggests that Ultra introduces additional effects that disproportionately tax the GPU.

Q: Is the i5-10400F holding back performance at 1080p?

A: Based on the benchmark results, the CPU appears adequate. The 1080p Low setting achieves 282.7 FPS, which is close to the practical limits of many displays. The CPU’s single-thread score of 688 in 3dmark_single_thread and its Cinebench R23 single-core score of 1453 indicate sufficient per-core capability.

Q: What is the frame rate difference between Medium and High at 4K?

A: The difference is modest. At 3840x2160, Medium averages 98.3 FPS while High averages 82.4 FPS, a gap of 15.9 FPS. This suggests that the visual upgrade from Medium to High costs roughly 16% performance at 4K.

Q: Does the GPU’s memory bandwidth affect 4K performance?

A: The RX 6600 has 8 GB of GDDR6 memory with a 128-bit bus and 224.0 GB/s bandwidth. The data shows a steep frame rate drop from 1440p to 4K, which is consistent with the GPU’s memory subsystem becoming a limiting factor at higher pixel counts, though the game itself is not memory-intensive.

How This Combo Ranks

In the database of tested combinations for Roblox, this specific pairing of the Intel Core i5-10400F and AMD Radeon RX 6600 holds a rank of 1470 out of 1800 tested combos. This places it in the lower-middle portion of the ranking table, which is surprising given the high absolute frame rates measured. The ranking reflects the relative performance against other combos, many of which may include more powerful CPUs or GPUs that push frame rates even higher in a game as lightweight as Roblox.

The combo’s percentile standing for the individual components provides context. The CPU ranks in the 73rd percentile against all CPUs, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552, which scores 14115 (0.4% lower), and the AMD Ryzen 3 7320C, which scores 14277 (0.8% higher). The GPU places in the 69th percentile against all GPUs, with an average score of 25235. Its closest competitor is the AMD Radeon 890M with a score of 25246 (0.0% delta), showing that the RX 6600 is essentially tied with that integrated solution in synthetic benchmarks.

The rank of 1470 out of 1800 means that roughly 18% of tested combos perform worse in Roblox. This seems counter-intuitive given the high FPS numbers, but the ranking likely favors combos with even higher refresh rates or lower latency. The data suggests that while this combo is far from the top of the leaderboard, it provides a smooth experience in absolute terms, with the 1080p Ultra result of 182.2 FPS being more than sufficient for most users.

Measured FPS Breakdown

At 1920x1080, the measured average frame rates are uniformly high. Low settings produce 282.7 FPS, Medium delivers 254.8 FPS, High achieves 224.4 FPS, and Ultra reaches 182.2 FPS. The gap between Low and Ultra is exactly 100.5 FPS, which indicates that the graphical settings have a substantial impact on performance even at this resolution. The progression from Low to Ultra shows a consistent decline, with each step up in quality costing roughly 20-30 FPS.

Moving to 2560x1440, the frame rates remain well above 120 FPS for all presets. Low settings yield 190.4 FPS, Medium drops to 170.1 FPS, High is at 152.2 FPS, and Ultra falls to 123.4 FPS. The relative performance scaling is similar to 1080p, but the absolute numbers are lower across the board. The difference between Low and Ultra at 1440p is 67 FPS, which is a smaller absolute gap than at 1080p, showing that the GPU is becoming more of a limiting factor.

At 3840x2160, the performance drops significantly. Low settings still manage 103.8 FPS, which is playable, but Medium and High fall to 98.3 FPS and 82.4 FPS respectively. Ultra is the most demanding, averaging 67.5 FPS. The spread from Low to Ultra at 4K is 36.3 FPS, which is the smallest absolute difference across all resolutions. This compression suggests that at 4K, the GPU’s raw throughput is the dominant constraint, and the settings-based differences are less pronounced than at lower resolutions.

GPU Role

The AMD Radeon RX 6600 plays a central role in determining the frame rate at higher resolutions. Its 8 GB of GDDR6 memory, operating on a 128-bit bus with 224.0 GB/s bandwidth, is sufficient for Roblox’s modest texture requirements, but the bandwidth becomes a limiting factor as resolution increases. The data shows a clear correlation: at 4K, the frame rates are roughly half of what they are at 1080p for the same settings, which aligns with the quadrupling of pixel count and the GPU’s inability to scale proportionally.

The GPU’s clock speeds provide insight into its performance characteristics. The base clock is 1626 MHz, the game clock is 2044 MHz, and the boost clock reaches 2491 MHz. The memory runs at 1750 MHz, translating to 14 Gbps effective. These clocks, combined with 1792 shading units and 64 ROPs, give the GPU a pixel rate of 159.4 GPixel/s and a texture rate of 279.0 GTexel/s. These specifications are more than adequate for a game like Roblox, which is not graphically intense, but the 4K results indicate that the GPU is still the primary bottleneck when pushing high pixel counts.

The GPU’s benchmark scores corroborate its mid-range positioning. It scores 15096 in Passmark G3D, placing it in the 69th percentile. Its DirectX 11 score of 152 and DirectX 12 score of 51 suggest that the card is better optimized for older API workloads, which is relevant for Roblox’s rendering pipeline. The GPU’s FP32 performance of 8.928 TFLOPS is respectable, but the data shows that this compute power is not fully utilized at lower resolutions, where the CPU can keep up and the frame rates are extremely high.

Settings Recommendations

For users prioritizing maximum frame rates, especially on high-refresh-rate 1080p monitors, the Low preset at 1920x1080 delivers the best result with an average of 282.7 FPS. This setting minimizes GPU load and allows the CPU to drive the frame rate to its peak. However, the data shows that even at Ultra settings, 1080p maintains 182.2 FPS, which is still well above the refresh rate of most standard monitors, so users can opt for higher visual fidelity without sacrificing playability.

At 1440p, the Medium preset appears to offer the best balance, achieving 170.1 FPS. This is only 20.3 FPS lower than Low but provides improved visual quality. High is also viable at 152.2 FPS, but Ultra drops to 123.4 FPS, which may be less desirable for competitive play. For 1440p users, the data suggests that sticking to Medium or High is the sweet spot, as the performance penalty for Ultra is steep.

For 4K gaming, the Low preset is the only option that comfortably exceeds 100 FPS, averaging 103.8 FPS. Medium is close at 98.3 FPS, which is still smooth, but High and Ultra fall to 82.4 FPS and 67.5 FPS respectively. Given the modest visual differences in Roblox, the data recommends using Low or Medium at 3840x2160 to maintain high frame rates, as the GPU is clearly the limiting factor at this resolution. Overall, the combination of the i5-10400F and RX 6600 is best utilized at 1080p or 1440p with medium-to-high settings, where it delivers consistently high performance across the board.
