Roblox

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3070 Ti delivers exceptional performance in Roblox, a title whose simple geometry and art style rarely stress modern hardware. The benchmark data shows that this combination is far more likely to be limited by the CPU’s single-thread performance than by the GPU’s raw fill rate. Across all tested resolutions and settings, the average frame rates are extraordinarily high, often exceeding the refresh rate of even premium gaming monitors. The measured results indicate a system that can push Roblox to its absolute limits, with the primary bottleneck shifting from the graphics card at 4K to the processor at 1080p.

Resolution Scaling

The frame rate scaling from 1080p to 4K clearly illustrates the shifting balance of component load. At 1080p with Low settings, the combo produces 438.1 FPS, which drops to 293.5 FPS at 1440p and further to 168 FPS at 4K. This represents a 61.7% reduction in frame rate from the lowest to the highest resolution at the same Low settings tier. The pattern is consistent across all settings; for instance, at High settings, the frame rate descends from 349.3 FPS at 1080p to 235 FPS at 1440p and finally to 129.8 FPS at 4K. This steep decline with rising pixel count indicates that the GPU is the primary limiting factor at 4K, as the increased pixel throughput demands more from the 3070 Ti’s memory bandwidth and shading units.

However, the sheer magnitude of these numbers reveals that even at 4K Ultra, the system still maintains an average of 109.2 FPS. This suggests that Roblox’s rendering workload is not particularly demanding on the RTX 3070 Ti, which is rated at 21.75 TFLOPS of FP32 performance. The data indicates that at lower resolutions, specifically 1080p, the CPU becomes the constraint. The jump from 1080p Low (438.1 FPS) to 1080p Ultra (283.5 FPS) is a 35.3% performance hit, which is less about GPU load and more about the increased CPU overhead for draw calls and physics at higher settings. The Intel Core i5-10400F, with its 2.90 GHz base and 4.30 GHz boost clock, delivers strong single-thread scores in synthetic tests, like its 1453 points in Cinebench R23 single-core, but those scores are still finite, and Roblox can push against that ceiling.

FAQ

Q: What is the highest average frame rate recorded for this combo in Roblox?

A: The highest average frame rate is 438.1 FPS, achieved at 1920x1080 resolution with Low settings.

Q: How does the frame rate drop when moving from 1440p to 4K at High settings?

A: At 2560x1440 High, the average is 235 FPS, which drops to 129.8 FPS at 3840x2160 High, a reduction of 105.2 FPS.

Q: Is the RTX 3070 Ti or the i5-10400F more likely to limit performance at 1080p?

A: At 1080p, the data suggests a CPU limitation. The frame rates are extremely high (over 349 FPS at High), but the scaling between Low (438.1 FPS) and Ultra (283.5 FPS) shows a performance gap that is more consistent with CPU overhead than GPU fill rate limits.

Q: What is the lowest average frame rate recorded in the measured results?

A: The lowest average frame rate is 109.2 FPS, which occurs at 3840x2160 resolution with Ultra settings.

Q: How does the combo’s performance rank among all tested configurations for this game?

A: The combo ranks 694th out of 1800 tested combinations, placing it in the top 38.6% of all systems tested for Roblox.

Q: What is the performance difference between Low and Ultra settings at 4K?

A: At 3840x2160, the Low setting yields 168 FPS, while Ultra yields 109.2 FPS, showing a 58.8 FPS difference between the two extremes.

How This Combo Ranks

The comboRankInGame data places this specific pairing at rank 694 out of 1800 tested combinations. This percentile placement is noteworthy given the hardware involved. The RTX 3070 Ti sits in the 74th percentile of all GPUs, and the i5-10400F is in the 73rd percentile of all CPUs, according to their respective benchmark averages. Yet, this combination does not crack the top 500, which suggests that other pairings with higher-end CPUs or more specialized GPUs manage to achieve even higher frame rates in Roblox. The data indicates that while this system is very fast, it is not the absolute pinnacle for this specific game.

The ranking implies that many other combos, likely featuring newer generation processors with higher single-thread scores, outperform this setup. For example, the i5-10400F’s nearest rival, the AMD Ryzen 3 7320C, has a similar average benchmark score (14277 vs 14168), but its architectural differences may translate into better Roblox performance. The rank of 694 suggests that the bottleneck is often the CPU, as the GPU’s 8 GB of GDDR6X memory and 608.3 GB/s bandwidth are more than sufficient for Roblox’s texture loads. The data shows that this combination is a high-performance pairing, but it is not the definitive best-in-class for this specific title, as the CPU’s 6 cores and 12 threads are more than adequate, yet its single-thread speed is not top-tier.

Measured FPS Breakdown

The measured data provides a comprehensive grid of performance. At 1920x1080, the frame rates are exceptionally high. Low settings deliver 438.1 FPS, Medium drops slightly to 395.4 FPS, High maintains 349.3 FPS, and Ultra settles at 283.5 FPS. The performance delta between Low and Ultra at 1080p is 154.6 FPS, indicating that while the GPU can handle the resolution, the increased settings demand more from the CPU’s processing of game logic.

Moving to 2560x1440, the numbers remain impressive. Low settings produce 293.5 FPS, Medium yields 264.7 FPS, High achieves 235 FPS, and Ultra records 190.4 FPS. The scaling is more linear here, with a 103.1 FPS difference between Low and Ultra. This suggests a more balanced load between CPU and GPU, as the higher pixel count starts to engage the RTX 3070 Ti more meaningfully.

At 3840x2160, the GPU becomes the clear limiting factor. Low settings still deliver a playable 168 FPS, Medium drops to 152 FPS, High falls to 129.8 FPS, and Ultra bottoms out at 109.2 FPS. The difference between Low and Ultra at 4K is 58.8 FPS, which is the smallest absolute gap across all resolutions. This indicates that the GPU’s pixel processing power is the primary constraint, and the CPU has enough headroom to feed it. The data shows that even at the most demanding settings, the system never dips below 100 FPS, proving it is more than capable of delivering a smooth experience on any display.

GPU Role

The NVIDIA GeForce RTX 3070 Ti is central to this combo’s high-resolution performance. Its 8 GB of GDDR6X memory on a 256-bit bus provides 608.3 GB/s of bandwidth, which is critical for maintaining high frame rates at 4K. The card’s boost clock of 1770 MHz allows it to reach a pixel rate of 169.9 GPixel/s and a texture rate of 339.8 GTexel/s. These specifications are far beyond what Roblox typically requires, which is why the GPU does not become a bottleneck until the resolution hits 4K with Ultra settings.

The GPU’s benchmark scores corroborate its strong position. It achieves a Passmark G3D score of 23356 and a Geekbench OpenCL score of 137518. Its nearest rivals, such as the AMD Radeon RX 6700, have a similar average benchmark score (31112 vs 30849), but the RTX 3070 Ti’s specific architecture with 6144 shading units is well-suited for this title. The data suggests that the GPU’s role is to provide a massive headroom, ensuring that the only limiting factor in Roblox is the CPU’s single-thread performance at lower resolutions. The card’s 21.75 TFLOPS of FP32 compute is effectively overkill for Roblox’s simple shaders, meaning that the measured frame rates are primarily dictated by how quickly the CPU can issue draw calls and update game state. The GPU’s 74th percentile ranking among all GPUs confirms its high-end status, but in Roblox, its immense power is only partially utilized, making the CPU the star of the show at 1080p.
