Roblox

Roblox with the Intel Core i5-14600KF and NVIDIA GeForce GTX 1070 delivers a decisively playable experience, but the data reveals a clear bottleneck shift as resolution increases. At 1080p, the system is heavily CPU-bound, producing frame rates that far exceed display refresh rates; at 4K, the GTX 1070 becomes the limiting factor, though performance remains respectable. This combo ranks in the 16th percentile of tested configurations, indicating that while it is not a top-tier performer, it holds its own in a crowded field.

Resolution Scaling

The measured FPS data shows a dramatic and consistent drop as resolution scales from 1920x1080 to 3840x2160, which is characteristic of a system where the GPU is progressively loaded more heavily. At 1080p with High settings, the combo averages 202.4 FPS, but this falls to 137.1 FPS at 1440p and further down to 73.8 FPS at 4K. This represents a 63.5% performance decline from 1080p to 4K, a steep curve that clearly identifies the GPU as the primary constraint at higher resolutions.

The scaling pattern is more revealing when examining the Low settings preset. At 1080p Low, the system pushes 252 FPS, but at 4K Low it still manages 92.5 FPS. The delta between 1080p and 1440p at Low settings is 83.9 FPS, while the drop from 1440p to 4K is 75.6 FPS. This relatively even distribution suggests that the GTX 1070 is being utilized more effectively as resolution increases, but the CPU's headroom at lower resolutions means the frame rate is not purely GPU-limited. The fact that 1080p Low (252 FPS) is only 24.5% faster than 1080p High (202.4 FPS) indicates that even at the lowest settings, the CPU is not the sole bottleneck — the GPU's shading and memory capabilities still factor in.

At 4K, the difference between Low (92.5 FPS) and Ultra (62.5 FPS) is exactly 30 FPS, a 48% swing. This shows that the GTX 1070's 8 GB of GDDR5 memory and 256-bit bus are sufficient to avoid catastrophic drops, but the 150 W TDP and Pascal architecture's limits become apparent under Ultra settings. The data suggests that the 1080p to 1440p transition is the sweet spot, where the i5-14600KF's 14 cores and 20 threads can still feed the GPU adequately, resulting in 137.1 FPS at 1440p High — a figure that remains well above the 60 FPS threshold for smooth gameplay.

How This Combo Ranks

The comboRankInGame field places this configuration at rank 1517 out of 1800 tested combos, meaning it sits in the 16th percentile of all tested pairings. This is a modest ranking, but it must be contextualized by the game's nature. Roblox is a sandbox title with a 2006 release date, and its engine is not particularly demanding on modern hardware. The ranking reflects that many other combos, likely those with newer GPUs, achieve higher raw frame rates, but the absolute performance here is still very playable.

Compared to the GPU's nearest rivals, the GTX 1070's average benchmark score of 12331 is only 0.7% higher than the NVIDIA Quadro K4200 (12241) and 1.4% lower than the NVIDIA GeForce GTX 1650 SUPER (12504). This places the GTX 1070 in a tight performance band where small deltas separate it from competitors. The 0.7% edge over the K4200 is negligible in real-world terms, but the 1.4% deficit to the GTX 1650 SUPER suggests that the latter is a marginally faster card in synthetic tests. However, in Roblox specifically, the measured FPS data shows the GTX 1070 delivering 252 FPS at 1080p Low, which is far above what most users would need.

The CPU's nearest rivals provide a different perspective. The i5-14600KF's average benchmark score is 49367, which is 0.4% higher than the i5-14600K (49166) and 0.6% higher than the AMD Ryzen 9 5950X (49062). The delta to the Intel Xeon Gold 5318H is 1.4%, meaning the i5-14600KF is notably faster in aggregate. This CPU is clearly not the limiting factor in this combo; the 16th percentile ranking is almost entirely attributable to the GPU's age and mid-range standing (51st percentile among all GPUs).

GPU Role

The NVIDIA GeForce GTX 1070 is a Pascal-architecture card built on a 16 nm process at TSMC, with 7,200 million transistors on a 314 mm² die. Its 8 GB of GDDR5 memory operates at 2002 MHz (8 Gbps effective) across a 256-bit bus, yielding 256.3 GB/s of bandwidth. These specifications are modest by 2024 standards, but the measured FPS in Roblox shows they are sufficient for smooth gameplay at most settings.

The GPU's clock speeds are 1506 MHz base and 1683 MHz boost, and its 1920 shading units are paired with 120 TMUs and 64 ROPs. The 6.463 TFLOPS of FP32 performance is a key metric, and it explains why the card begins to struggle at 4K Ultra (62.5 FPS). The 4K Ultra setting demands more pixel throughput, and the 64 ROPs can only fill so many pixels per second (107.7 GPixel/s). In contrast, at 1080p Low, the pixel rate requirement is far lower, allowing the card to hit 252 FPS.

The GTX 1070's benchmark results show a Passmark G3D score of 13498, placing it in the 51st percentile of all GPUs. Its nearest rivals — the Quadro K4200, GTX 880M, GTX 1650 SUPER, and Tesla K20Xm — all have average scores within 1.7% of it, confirming that this is a mid-range card. The 8 GB VRAM is not a limiting factor in Roblox, as even at 4K Ultra the card maintains over 60 FPS, indicating that memory capacity is sufficient for this game's textures. The GPU's 150 W TDP and dual-slot design are also consistent with its mid-range positioning, and the 1x 8-pin power connector is standard for this class.

Measured FPS Breakdown

At 1920x1080, the combo delivers exceptional performance across all settings. Low is the fastest at 252 FPS, followed by Medium at 229.4 FPS, High at 202.4 FPS, and Ultra at 163.7 FPS. The gap between Low and Ultra is 88.3 FPS, which is a 54% difference, showing that the GPU's shading units and memory bandwidth are exercised more heavily at higher presets. Even at Ultra, the 163.7 FPS figure is far above any standard 60 Hz or 144 Hz display's refresh rate, making this resolution overkill for the game's visuals.

At 2560x1440, performance remains strong but begins to show GPU limitations. Low hits 168.1 FPS, which is 83.9 FPS lower than at 1080p. Medium drops to 154.7 FPS, High to 137.1 FPS, and Ultra to 112.6 FPS. The Ultra preset at 1440p is 51.1 FPS slower than its 1080p counterpart, a 31% reduction, indicating that the GPU is now the primary bottleneck. The 112.6 FPS at 1440p Ultra is still smooth, but the scaling from Low to Ultra at this resolution is a 55.5 FPS spread, which is consistent with the GPU's mid-range capabilities.

At 3840x2160, the GTX 1070 is clearly the limiting component. Low averages 92.5 FPS, Medium 86 FPS, High 73.8 FPS, and Ultra 62.5 FPS. The Low-to-Ultra spread is exactly 30 FPS, and the Ultra result is just above the 60 FPS playability threshold. The drop from 1440p High (137.1 FPS) to 4K High (73.8 FPS) is 63.3 FPS, a 46% reduction, which is a typical penalty for quadrupling the pixel count. The 4K Low result of 92.5 FPS shows that the card can still perform respectably if settings are reduced, but the Ultra preset at 4K is the only configuration that approaches the 60 FPS line.

Settings Recommendations

The measured data suggests that the optimal experience is achieved at 2560x1440 with High settings. This configuration yields 137.1 FPS, which is 74.6 FPS higher than the 4K High result and only 31.5 FPS lower than the 1080p High result. The 1440p High preset offers a substantial visual upgrade over 1080p while maintaining frame rates well above 120 FPS, making it ideal for high-refresh-rate displays.

For users prioritizing maximum frame rates, 1080p Low delivers 252 FPS, which is 88.3 FPS faster than 1080p Ultra. However, this comes at the cost of visual quality in a game that relies on user-generated content. A more balanced choice is 1080p Medium at 229.4 FPS, which provides a 26.6 FPS improvement over High settings while still looking decent.

At 4K, the data suggests using Low settings (92.5 FPS) rather than Ultra (62.5 FPS), as the 30 FPS gain is substantial and the visual difference in Roblox's blocky aesthetic is often minimal. The 4K Medium preset (86 FPS) is also a reasonable compromise, offering 23.5 FPS more than Ultra while maintaining a higher quality level than Low. Given that the GTX 1070 has 8 GB of VRAM, memory capacity is not a concern at any setting, so the choice should be driven by the FPS targets shown in the measured rows.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process. Its 3.50 GHz base clock boosts to 5.30 GHz, and it has 24 MB of shared L3 cache. The CPU's benchmark scores are impressive: a Cinebench R23 multi-core score of 32889 and a single-core score of 4643, with a Geekbench multi-core score of 15636.

In this combo, the CPU is clearly not the limiting factor at any resolution. The measured FPS data shows that at 1080p Low, the system achieves 252 FPS, which is a figure that most CPUs would struggle to sustain in other games. The 93rd percentile ranking among all CPUs (average benchmark score 49367) confirms that the i5-14600KF is a high-end processor. Its nearest rival, the i5-14600K, has an average score of 49166, a delta of only 0.4%, meaning the KF variant is effectively identical in performance.

The CPU's 14 cores and 20 threads are overkill for Roblox, which is not a heavily threaded title. The single-core performance, evidenced by the Geekbench single-core score of 2778, is more relevant, and it allows the GTX 1070 to run at its full potential at lower resolutions. The data shows that the CPU can push frame rates well beyond 200 FPS at 1080p, indicating that it would not bottleneck even a significantly faster GPU. The 125 W TDP and Socket 1700 compatibility are standard for this class, and the CPU's support for DDR4 and DDR5 memory (dual-channel) provides flexibility in system configuration.
