Roblox

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4070 produces exceptionally high frame rates in Roblox, with the data showing a clear progression of performance scaling as resolution increases. At 1080p, the combination delivers average frame rates well above 300 FPS across all settings, with the Low preset reaching 502.4 FPS. Moving to 1440p, the averages remain robust, spanning from 218.8 FPS at Ultra to 338.9 FPS at Low. At 4K, the system still maintains triple-digit performance, with the Ultra preset yielding 124 FPS and High settings producing 155.9 FPS. The frame rate drop from 1080p Low to 4K Low is substantial, going from 502.4 FPS down to 191.7 FPS, a reduction that highlights the increasing graphical demand placed on the system at higher resolutions.

The scaling behavior across resolutions reveals that the RTX 4070 becomes progressively more involved as pixel count rises. The gap between the Low and Ultra presets narrows significantly at 4K, where the difference is 67.7 FPS (191.7 vs 124), compared to a 174.6 FPS gap at 1080p (502.4 vs 327.8). This compression of performance at higher resolutions indicates that the GPU is working closer to its limits, though it remains capable of delivering playable frame rates even in the most demanding configuration tested. The data suggests that at 1080p, the system's performance is likely constrained by other factors, possibly the CPU's instruction throughput, given the extremely high frame rates that exceed typical display refresh rates.

Resolution Scaling

The measured FPS data shows a consistent pattern of performance degradation as resolution increases, which is expected behavior for a GPU-bound workload. At 1080p High, the system produces 402.1 FPS, which drops to 270 FPS at 1440p High and further to 155.9 FPS at 4K High. The percentage decrease from 1080p to 1440p is approximately 32.8%, while the drop from 1440p to 4K is about 42.3%. This steeper decline at higher resolutions indicates that the RTX 4070's rendering capabilities are being taxed more heavily, with the 4K Ultra setting showing the most significant performance hit at 124 FPS.

The Low preset exhibits the most dramatic scaling, with 502.4 FPS at 1080p dropping to 338.9 FPS at 1440p and then to 191.7 FPS at 4K. This represents a total reduction of 61.8% from the lowest to highest resolution tested. The Medium settings follow a similar trajectory, starting at 456.1 FPS at 1080p, falling to 307.8 FPS at 1440p, and ending at 171 FPS at 4K. The Ultra preset shows the smallest absolute frame rate range, from 327.8 FPS at 1080p to 124 FPS at 4K, suggesting that the higher graphical fidelity settings are more consistently demanding across all resolutions.

The limiting component shifts based on resolution. At 1080p, the extremely high frame rates, particularly the 502.4 FPS result on Low settings, suggest that the CPU's 6 cores and 12 threads may be reaching their limit in terms of game logic and draw call processing. The i5-10400F has a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with benchmark scores indicating solid single-thread performance. As resolution increases, the GPU becomes the primary bottleneck, as evidenced by the narrowing performance gap between settings at 4K.

CPU Role

The Intel Core i5-10400F provides the computational foundation for this combination, featuring 6 cores and 12 threads based on the Comet Lake architecture. Its 14 nm process node and 12 MB of shared L3 cache contribute to its benchmark performance, with the Cinebench R23 multicore score reaching 10297 and the single-core score at 1453. The processor's 3DMark scores show scaling across thread counts, from 1350 with 2 threads to 4748 with 16 threads, indicating reasonable multi-threading efficiency for a desktop part.

In Roblox, the CPU's role is critical for maintaining high frame rates, particularly at lower resolutions where the GPU is not the primary constraint. The i5-10400F's boost clock of 4.30 GHz provides strong single-threaded performance, which is often the limiting factor in games that rely heavily on a single game thread. The PassMark single-thread score of 2541 and the Geekbench single-core score of 1454 both indicate capable per-core performance. The processor's 65 W TDP and Intel Socket 1200 compatibility are noted in the specifications, though the performance data is what matters most for this analysis.

The CPU's benchmark results place it in the 73rd percentile among all processors, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552, which scores 14115, and the AMD Ryzen 3 7320C, which scores 14277. The i5-10400F trails these competitors by small margins, with delta percentages of 0.4% and -0.8% respectively. This positioning suggests that the CPU is competitive in its class, though not at the top tier, which is consistent with its 10th-generation status and 14 nm manufacturing process.

GPU Role

The NVIDIA GeForce RTX 4070 is the more powerful component in this pairing, built on the Ada Lovelace architecture with a 5 nm process node at TSMC. The GPU features 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of bandwidth. Its core configuration includes 5888 shading units, 184 texture mapping units, and 64 raster output units, with 46 RT cores and 184 tensor cores. The GPU's clock speeds are specified at 1920 MHz base and 2475 MHz boost, with memory running at 1313 MHz effectively delivering 21 Gbps.

In Roblox, the GPU's role becomes increasingly prominent at higher resolutions and quality settings. The 4K Ultra preset, which yields 124 FPS, demonstrates the GPU's ability to handle substantial graphical workloads while still maintaining playable performance. The RTX 4070's FP32 compute capability of 29.15 TFLOPS and its pixel rate of 158.4 GPixel/s contribute to its rendering efficiency. The GPU's benchmark scores show strong DirectX performance, with PassMark DirectX 11 scoring 244 and DirectX 12 scoring 103, while the Geekbench Vulkan result reaches 157352.

The GPU's 81st percentile ranking among all GPUs, with an average benchmark score of 37283, positions it well above the CPU in relative performance. Its nearest rivals include the AMD Radeon RX Vega 56, which scores 37507, and the NVIDIA GeForce RTX 4080 Mobile, which scores 38135. The RTX 4070 trails these by margins of -0.6% and -2.2% respectively, while leading the AMD Radeon RX 5300M by 2.5%. This data indicates that the GPU is a high-performing part that can handle the demands of Roblox at all tested settings and resolutions.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across all combinations of resolution and settings. At 1920x1080, the system achieves 502.4 FPS on Low settings, 456.1 FPS on Medium, 402.1 FPS on High, and 327.8 FPS on Ultra. These results show that even at the most demanding 1080p setting, the system maintains frame rates well above the 300 FPS threshold, indicating that the combination is not significantly challenged at this resolution.

Moving to 2560x1440, the performance remains strong but shows clear scaling. The Low preset delivers 338.9 FPS, Medium produces 307.8 FPS, High reaches 270 FPS, and Ultra drops to 218.8 FPS. The transition from 1080p to 1440p results in performance reductions ranging from 32.5% (Low) to 33.3% (Ultra), showing relative consistency across settings. The 1440p results still provide ample headroom for high-refresh-rate displays, with even the Ultra preset exceeding 200 FPS.

At 3840x2160, the system's performance becomes more constrained. The Low setting yields 191.7 FPS, Medium produces 171 FPS, High achieves 155.9 FPS, and Ultra drops to 124 FPS. The 4K results show a more pronounced difference between settings, with the gap between Low and Ultra widening to 67.7 FPS. Despite these lower numbers, all 4K configurations maintain frame rates above 120 FPS, ensuring smooth gameplay even at the highest resolution tested.
