Roblox

Roblox is a game that scales dramatically across resolutions for this Intel Core i5-13400F and NVIDIA GeForce RTX 5070 pairing, and the data reveals a system that is rarely the bottleneck. At 1080p, the average frame rates are so high that they suggest the game’s engine, rather than the hardware, is setting the practical ceiling. The measured results show a 541.4 FPS average at Low settings, which is an extraordinary figure that speaks to the raw speed of the combination. However, the drop from 1080p to 1440p is steep, and the further drop to 4K is even more pronounced, showing how the rendering load shifts from the CPU to the GPU as pixel count increases.

Resolution Scaling

The frame rate scaling across resolutions is the most telling aspect of this data set, as it shows a clear transition in bottleneck behavior. Moving from 1920x1080 to 2560x1440 at High settings, the average FPS falls from 435.3 to 290.6, a reduction of 33%. This is a substantial decline, but it is not as severe as the drop from 1440p to 4K. At 3840x2160 High, the system produces 164.2 FPS, which is a 43% reduction from the 1440p figure. This pattern indicates that at 1080p, the CPU and the game's logic are likely the limiting factors, since the GPU has ample headroom to render frames quickly. As resolution increases, the pixel fill rate demands on the RTX 5070 grow, and the GPU begins to dominate the performance equation.

The Low settings preset provides the clearest view of this scaling. At 1080p Low, the system hits 541.4 FPS, but at 1440p Low, it drops to 363.1 FPS, and at 4K Low, it falls to 204.8 FPS. The 4K Low result is particularly interesting because it is still exceptionally high, yet it represents a 62% reduction from the 1080p Low score. This suggests that even at the lowest graphical load, the GPU's memory bandwidth and processing power are being heavily taxed at 4K. The data implies that a user with a high-refresh-rate 1080p monitor will be completely satisfied, while a 4K display will still yield a smooth experience, but the system will be working much harder to maintain those high numbers.

How This Combo Ranks

Within the database of tested combinations, this specific pairing of the Intel Core i5-13400F and the NVIDIA GeForce RTX 5070 holds a rank of 413 out of 1800 combinations for Roblox. This places it in the top 23% of all tested systems, which is a strong showing for a game that is not typically considered a demanding title. The percentile data for the individual components supports this high ranking. The CPU sits at the 82nd percentile against all other processors in the database, while the GPU is at the 83rd percentile against all other graphics cards. This symmetry suggests a balanced pairing, where neither component is drastically underpowered or overpowered relative to the other.

The rank is more impressive when considering the nature of Roblox, which is often thought of as a lightweight game. The fact that this combo still ranks in the top quarter of all systems indicates that the high frame rates are not just a product of the game's simplicity, but also the raw computational power of the RTX 5070 and the 13th Gen Core i5. The nearest rival data for the GPU shows it is performing within 0.7% of the AMD Radeon Pro 580X in average benchmark scores, which is a negligible difference. For the CPU, the closest rival is the Intel Core i7-13620H, with a delta of just 0.1%, meaning the i5-13400F is statistically tied with that mobile part in average synthetic performance.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how the system handles different quality presets. At 1920x1080, the frame rates are exceptionally high across the board. The Low preset leads with 541.4 FPS, followed by Medium at 494 FPS, High at 435.3 FPS, and Ultra at 353.4 FPS. This shows that even at the highest settings, the system maintains a frame rate well above what most displays can show, indicating a CPU-bound scenario where the game's thread utilization is the limiting factor.

Moving to 2560x1440, the performance remains very strong but begins to show the GPU's influence. The Low preset delivers 363.1 FPS, Medium is at 327.8 FPS, High is at 290.6 FPS, and Ultra drops to 235.6 FPS. The gap between Low and Ultra at this resolution is 127.5 FPS, which is a larger absolute difference than at 1080p. This indicates that the GPU is starting to work harder, but the system is still far from being stressed.

At 3840x2160, the frame rates are still high but show a more pronounced difference between presets. Low yields 204.8 FPS, Medium is at 185.4 FPS, High is at 164.2 FPS, and Ultra drops to 132.7 FPS. The scaling from Low to Ultra at 4K is a 35% reduction, which is consistent with the 1440p result. The data shows that the RTX 5070 is capable of delivering a playable experience at 4K Ultra, but the frame rate is now in a range where a high-refresh-rate monitor would be fully utilized.

GPU Role

The NVIDIA GeForce RTX 5070 is the dominant factor in this system's high-resolution performance. Its architecture is Blackwell 2.0, built on a 5 nm process, and it features 6144 shading units. The GPU has a base clock of 2325 MHz and a boost clock of 2512 MHz, which are the frequencies that drive its raw computational throughput. The memory subsystem is a key component, featuring 12 GB of GDDR7 memory on a 192-bit bus, providing a bandwidth of 672.0 GB/s. This bandwidth is critical for Roblox at 4K, as the game's blocky textures and simple geometry still require rapid data transfer to maintain high frame rates.

The GPU's compute capabilities are substantial, with an FP32 performance of 30.87 TFLOPS. This raw power is what allows the card to achieve 204.8 FPS at 4K Low settings. The data shows that the GPU is not the bottleneck at 1080p, as the frame rates are nearly identical across the Low and Medium presets, suggesting that the CPU is the limiting factor. However, at 4K, the GPU's role becomes much more significant, with a 35% performance drop from Low to Ultra, demonstrating that the card's shading units and memory bandwidth are being fully utilized. The GPU's average benchmark score of 41687 places it in the 83rd percentile, and its nearest rival, the AMD Radeon Pro 5300, is only 0.2% slower, showing that this is a high-performance part.

CPU Role

The Intel Core i5-13400F plays a crucial role in the lower resolution results, where its 10 cores and 16 threads can fully express their capabilities. The CPU has a base clock of 2.50 GHz and a boost clock of 4.60 GHz, which are the frequencies that determine its single-threaded performance. This is particularly important for Roblox, which often relies on a single main thread for game logic. The CPU's single-thread benchmark scores, such as the 3004 in Cinebench R23, indicate a strong per-core performance that is well-suited for this game.

The 20 MB of shared L3 cache is also a factor in the high frame rates at 1080p. At that resolution, the GPU is not heavily taxed, and the CPU's ability to process game logic and feed draw calls to the GPU becomes the limiting factor. The data supports this, showing that at 1080p, the frame rates are extremely high but the differences between presets are relatively small. The CPU's 82nd percentile ranking against all processors confirms its balanced performance. Its nearest rival, the Intel Core i7-13620H, has an average score that is just 0.1% higher, indicating that the i5-13400F is a top-tier performer in its class. However, as resolution increases, the CPU's influence wanes, and the GPU takes over as the primary performance driver.

Settings Recommendations

For users with a 1080p or 1440p display, the Ultra preset is the clear recommendation, as the data shows that the system can maintain average frame rates of 353.4 FPS and 235.6 FPS, respectively. These numbers are well above the refresh rate of most monitors, so the visual fidelity of Ultra comes at no practical cost to the user experience. The performance difference between Low and Ultra at these resolutions is significant in raw numbers, but the absolute frame rates are so high that the difference is imperceptible on standard displays.

At 4K resolution, the choice of preset becomes more meaningful. The Ultra preset delivers 132.7 FPS, which is still a very smooth experience for most users. However, for those seeking the absolute highest frame rates, the Low preset at 204.8 FPS offers a 54% performance increase over Ultra. Given that Roblox is a game where visual fidelity is often less important than responsiveness, the Medium preset at 185.4 FPS provides an excellent balance between image quality and performance. The data suggests that for this combination, the best experience at 4K is achieved with the Medium settings, as it offers a substantial reduction in frame rate compared to Low, but a significant boost over High and Ultra, ensuring the system remains fluid in all scenarios.
