Roblox

Roblox presents a unique benchmarking challenge because its visual load can scale dramatically depending on user-generated content, yet the underlying engine remains accessible to older hardware. The measured data for the Intel Core i5-10400F paired with the AMD Radeon RX 570 shows a configuration that is clearly capable of playable frame rates across most settings, but with distinct performance characteristics that shift depending on resolution. This analysis breaks down the measured FPS data, component roles, and how this specific combo stacks up against the broader database of tested configurations.

Resolution Scaling

The frame rate drop from 1080p to 4K is substantial across all settings, but the pattern reveals important information about where the bottleneck lies. At 1080p with Low settings, the combo achieves 147.8 FPS, which drops to 101.1 FPS at 1440p and further to 58.8 FPS at 4K. This represents a 60.2% reduction in frame rate from 1080p to 4K at Low settings, indicating that the GPU is being increasingly taxed as pixel count rises. The scaling is not linear, though, as the jump from 1080p to 1440p costs 46.7 FPS, while the jump from 1440p to 4K costs another 42.3 FPS.

At Ultra settings, the same pattern holds but with a more pronounced absolute drop. The 1080p Ultra result of 99 FPS falls to 67.2 FPS at 1440p and then to 34.8 FPS at 4K. The 4K Ultra result is the only measured configuration that dips below 40 FPS, suggesting that this resolution and settings combination pushes the RX 570 beyond its comfortable operating range. Interestingly, the scaling from High to Ultra at 4K is particularly steep, with a drop from 47.3 FPS to 34.8 FPS, a 12.5 FPS penalty that is larger than the corresponding drop at 1440p (from 82.7 FPS to 67.2 FPS).

The data shows that at 1080p, the CPU has more headroom, as evidenced by the high frame rates even at High settings (116.4 FPS). The GPU becomes the limiting factor primarily at 4K, where even Low settings produce only 58.8 FPS. At 1440p, the combo strikes a balance, with Medium settings delivering 89.1 FPS, which is smooth for most gameplay scenarios. The 4K Ultra result of 34.8 FPS is the clearest indicator that this configuration is not designed for maximum visual fidelity at maximum resolution, though the 4K Low result of 58.8 FPS remains playable.

GPU Role

The AMD Radeon RX 570 features 4 GB of GDDR5 memory on a 256-bit bus, providing 224.0 GB/s of bandwidth. The GPU operates at a base clock of 1168 MHz with a boost clock of 1244 MHz, and its memory runs at 1750 MHz (7 Gbps effective). These specifications place the card in a specific performance tier, and the benchmark data shows it sitting at the 74th percentile among all GPUs, with an average benchmark score of 30158.

The VRAM capacity appears to be a meaningful factor in the 4K results. The 4K Ultra setting demands more memory for textures and effects, and the 4 GB frame buffer likely contributes to the significant frame rate drop to 34.8 FPS. At lower resolutions, the 4 GB capacity is less of a constraint, allowing the GPU to utilize its 2048 shading units and 128 texture mapping units more effectively. The pixel rate of 39.81 GPixel/s and texture rate of 159.2 GTexel/s provide the raw throughput needed for the 1080p and 1440p results.

The GPU's nearest rivals in the database include the NVIDIA GeForce RTX 5060 with an average score of 30109 (0.2% difference) and the AMD Radeon RX 7700 XT with a score of 30097 (0.2% difference). This clustering of scores suggests that the RX 570's overall compute capability is comparable to these more recent cards in synthetic benchmarks, though the real-world gaming results in Roblox show the RX 570 holding its own at lower resolutions. The 5.095 TFLOPS FP32 performance is the theoretical peak, and the measured data confirms that this translates to playable frame rates up to 1440p.

How This Combo Ranks

In the database of tested CPU-GPU combinations for Roblox, this specific pairing ranks 1698 out of 1800 combos. This places it in the lower percentile of tested configurations, which is expected given the hardware's age and tier. The rank of 1698 out of 1800 means that only 102 tested combos perform worse, indicating that while this setup is not near the top, it is far from the bottom of the performance spectrum.

The CPU itself sits at the 73rd percentile among all CPUs, with an average benchmark score of 14168. Its nearest rivals include the AMD EPYC 7552 with an average score of 14115 (0.4% higher), the AMD Ryzen 3 7320C at 14277 (0.8% higher), and the Intel Core i5-8500 at 14332 (1.1% higher). These close scores suggest that the i5-10400F is well-positioned within its performance class, and the combo rank reflects the combined capabilities of both components.

The GPU's 74th percentile ranking is slightly higher than the CPU's 73rd percentile, suggesting that the GPU is marginally the stronger component in this pairing. However, the combo rank of 1698 out of 1800 indicates that in Roblox specifically, the overall performance is constrained by the combination's ability to handle the game's rendering demands. The data shows that this combo outperforms roughly 5.7% of tested configurations, which is a modest but not insignificant position.

Measured FPS Breakdown

At 1920x1080, the results show a clear progression across settings. Low settings deliver 147.8 FPS, Medium drops to 136.1 FPS, High reduces to 116.4 FPS, and Ultra bottoms out at 99 FPS. The gap between Low and Ultra is 48.8 FPS, which is significant but still leaves the Ultra setting comfortably above 60 FPS. The transition from Medium to High costs 19.7 FPS, which is the largest single-step drop at this resolution, indicating that High settings introduce a noticeable increase in GPU workload.

Moving to 2560x1440, the frame rates scale down proportionally. Low produces 101.1 FPS, Medium delivers 89.1 FPS, High achieves 82.7 FPS, and Ultra falls to 67.2 FPS. The 1440p results show that all settings remain above 60 FPS, with Low even exceeding 100 FPS. The drop from 1080p to 1440p at Low settings is 46.7 FPS, while at Ultra the drop is 31.8 FPS, suggesting that the GPU is less sensitive to resolution changes at higher settings where other factors dominate.

At 3840x2160, the results become more constrained. Low settings deliver 58.8 FPS, Medium drops to 52.8 FPS, High reduces to 47.3 FPS, and Ultra falls to 34.8 FPS. The 4K results are the only ones where any setting falls below 60 FPS, and Ultra dips below 40 FPS. The scaling from 1440p to 4K at Low settings is a 42.3 FPS drop, while at Ultra the drop is 32.4 FPS. This pattern suggests that at 4K, the GPU is thoroughly saturated, and the differences between settings become less pronounced in absolute terms.

CPU Role

The Intel Core i5-10400F brings six cores and twelve threads to the pairing, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. This Comet Lake architecture processor has a 12 MB shared L3 cache and supports DDR4 memory with a dual-channel bus providing 42.7 GB/s of bandwidth. The CPU's benchmark results show a single-thread score of 2541 in Passmark and a multithread score of 12115, with Cinebench R23 scores of 1453 single-core and 10297 multi-core.

In Roblox, the CPU's role is less demanding than in many modern titles, as the game's engine is generally more GPU-bound. The measured frame rates at 1080p Low (147.8 FPS) suggest that the CPU can feed the GPU adequately at lower resolutions, but the 4K results show a different story. At 4K Ultra, the frame rate drops to 34.8 FPS, which is likely more GPU-limited than CPU-limited, given that the GPU is handling a significantly higher pixel load.

The CPU's nearest rivals include the AMD EPYC 7552 with an average score of 14115 (0.4% higher), the AMD Ryzen 3 7320C at 14277 (0.8% higher), and the Intel Core i5-8500 at 14332 (1.1% higher). These close scores indicate that the i5-10400F's compute performance is competitive with these alternatives, and the 12 threads provide ample parallelism for Roblox's background processes. The 65 W TDP and 14 nm process node make it an efficient choice, though the data shows that the GPU is the more significant factor in determining overall frame rates in this game.
