Roblox

Roblox is a sandbox title where performance can scale dramatically based on user-generated content and world complexity. The measured data for the Intel Core i5-14400F and NVIDIA GeForce RTX 3080 Ti combination shows a system that is overwhelmingly capable of running the game at high frame rates across all tested resolutions and settings. The benchmark results indicate that the primary challenge is not achieving playability, but rather managing the sheer volume of frames generated, with the system exceeding 500 FPS at the most modest settings.

Settings Recommendations

Based on the measured FPS rows, the optimal experience balances visual fidelity with the high refresh rate capabilities of this hardware. At 1920x1080, the High preset delivers an average of 402 FPS, which is a dramatic improvement over the 326 FPS average of the Ultra preset while retaining most visual quality enhancements. The data shows that the step from High to Ultra at this resolution costs roughly 76 FPS, a significant 18.9% reduction in frame rate for what is typically a marginal visual gain in a sandbox environment. The Medium preset at 1080p produces 455 FPS, but the High setting offers a more balanced visual package without dropping below the 400 FPS threshold.

For 2560x1440, the High preset remains the recommended choice, producing an average of 268 FPS. The 1440p High setting still provides a comfortable margin above 240 Hz displays while maintaining better visual quality than the 334 FPS Low preset. The Medium preset at this resolution averages 304 FPS with a minimum of 258 FPS, indicating that even in complex scenes, the system maintains high frame rates. However, the High preset's 268 FPS average with no recorded minimum suggests it holds up well in demanding scenarios without the potential visual artifacts of lower settings.

At 3840x2160, the recommendation shifts to the Medium preset, which averages 172 FPS with a recorded minimum of 146 FPS and maximum of 197 FPS. This is the only 4K preset with complete min/max data, showing that the frame time variance is manageable. The High preset at 4K averages 152 FPS, which is still excellent for 4K gaming, but the Medium preset's higher average and the availability of frame pacing data make it the safer choice for consistent performance. The Ultra preset at 4K drops to 123 FPS, which, while playable, begins to approach the threshold where frame drops become noticeable on high-refresh displays. The Low preset at 4K offers 189 FPS, but the visual compromises are substantial for a game that relies on user-generated content presentation.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this configuration for Roblox performance, particularly as resolution increases. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, providing 912.4 GB/s of bandwidth. The memory clock runs at 1188 MHz with 19 Gbps effective speed, while the core operates at a base clock of 1365 MHz and a boost clock of 1665 MHz. These specifications allow the GPU to handle the geometry and texture loads common in user-generated Roblox worlds without becoming a bottleneck at lower resolutions.

The benchmark results show that the RTX 3080 Ti's role becomes more critical as resolution scales up. At 1920x1080, the frame rates are so high (ranging from 326 to 500 FPS) that the CPU's ability to feed the GPU becomes a factor, but the GPU still dictates the overall scaling between presets. The difference between Low and Ultra at 1080p is 174 FPS (500 vs 326), which is a 34.8% reduction purely from settings pressure on the GPU. At 1440p, the same comparison shows a 116 FPS difference (334 vs 218), representing a 34.7% reduction, indicating the GPU maintains consistent scaling behavior.

At 3840x2160, the GPU's workload increases substantially, and the data shows the RTX 3080 Ti handles it admirably. The 4K Low preset at 189 FPS demonstrates that even at maximum resolution, the GPU has significant headroom. However, the 4K Ultra preset at 123 FPS shows the GPU is being pushed harder, as the settings increase the per-pixel work. The GPU's 34.10 TFLOPS of FP32 performance and 532.8 GTexel/s texture rate are sufficient to maintain these frame rates, but the data suggests that the GPU is the primary scaling factor at 4K, as the frame rate differences between presets become more pronounced at higher resolutions.

How This Combo Ranks

In the benchmark database for Roblox, this specific combination of the Intel Core i5-14400F and NVIDIA GeForce RTX 3080 Ti ranks 992 out of 3711 tested combos. This places the system in the top 26.7% of all tested configurations, indicating that it performs well above the median for this game. The ranking reflects that while the hardware is powerful, there are many other combinations that achieve higher frame rates in Roblox, likely due to the game's unique optimization characteristics and the potential for CPU-bound scenarios in certain user-generated content.

The combo's ranking is influenced by both components' strengths. The RTX 3080 Ti sits in the 83rd percentile of all GPUs, with an average benchmark score of 41187.

The data shows that this combo provides an excellent baseline for Roblox, but users seeking the absolute maximum frame rates might look at higher-ranked configurations.

Resolution Scaling

The measured FPS data reveals how the system's performance scales across resolutions, indicating where the bottleneck shifts. Moving from 1920x1080 to 2560x1440 at the High preset, the average frame rate drops from 402 FPS to 268 FPS, a reduction of 134 FPS or 33.3%. This significant drop suggests that the GPU is becoming more heavily utilized as pixel count increases, but the system still maintains very high performance. The scaling from 1440p to 4K at High settings shows a further drop from 268 FPS to 152 FPS, a 116 FPS reduction or 43.3% decrease. The percentage drop increases with resolution, which is typical of GPU-bound scenarios where the rendering workload grows faster than the linear resolution increase.

At the Medium preset, the scaling pattern is similar but with different magnitudes. The 1080p Medium average is 455 FPS, dropping to 304 FPS at 1440p (a 33.2% reduction) and then to 172 FPS at 4K (a 43.4% reduction from 1440p). The consistency in these percentage drops across presets indicates that the GPU is the primary limiting factor as resolution increases, with the CPU maintaining sufficient performance to feed the GPU at all tested settings. The Low preset shows the same trend: 500 FPS at 1080p, 334 FPS at 1440p (33.2% drop), and 189 FPS at 4K (43.4% drop from 1440p).

The Ultra preset follows the same pattern, with 326 FPS at 1080p, 218 FPS at 1440p (33.1% drop), and 123 FPS at 4K (43.6% drop from 1440p). The near-identical percentage drops across all presets strongly indicate that the GPU is the limiting component in resolution scaling. The consistent ~33% drop from 1080p to 1440p and ~43% drop from 1440p to 4K across all settings suggests that the rendering pipeline is handling the increased pixel workload uniformly, with the RTX 3080 Ti's capabilities determining the final frame rates. The CPU's role becomes less significant at higher resolutions, as the GPU takes longer to render each frame, reducing the frequency at which the CPU needs to submit new draw calls.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional frame rates across all settings. The Low preset produces the highest average at 500 FPS, with no recorded minimum or maximum values. The Medium preset averages 455 FPS, with a minimum of 387 FPS and a maximum of 523 FPS, showing a 136 FPS range between the lowest and highest measured frames. The High preset averages 402 FPS, while the Ultra preset averages 326 FPS. The progression from Low to Ultra at 1080p shows a 174 FPS reduction, with each step up in settings costing roughly 50-75 FPS.

At 2560x1440, the frame rates remain high but show clear scaling. The Low preset averages 334 FPS, the Medium preset averages 304 FPS with a minimum of 258 FPS and maximum of 349 FPS, the High preset averages 268 FPS, and the Ultra preset averages 218 FPS. The difference between Low and Ultra at 1440p is 116 FPS, a smaller absolute gap than at 1080p but a similar relative percentage. The Medium preset's min/max data at 1440p shows a 91 FPS range, indicating slightly tighter frame pacing than at 1080p.

At 3840x2160, the system still delivers high frame rates but with more pronounced setting-based differences. The Low preset averages 189 FPS, the Medium preset averages 172 FPS with a minimum of 146 FPS and maximum of 197 FPS, the High preset averages 152 FPS, and the Ultra preset averages 123 FPS. The 4K Medium preset shows a 51 FPS range between minimum and maximum, which is the tightest relative spread across all resolutions. The total spread from Low to Ultra at 4K is 66 FPS, demonstrating that the GPU has less headroom to differentiate settings at higher resolutions.

CPU Role

The Intel Core i5-14400F provides the processing foundation for this configuration, featuring 10 cores and 16 threads. The CPU operates with a base clock of 2.50 GHz and a boost clock of 4.70 GHz, with a 65W TDP. The Raptor Lake architecture includes 20 MB of shared L3 cache, with 1.25 MB of L2 cache per core and 80 KB of L1 cache per core. This configuration delivers strong single-threaded performance, as evidenced by its Cinebench R23 single-core score of 3055 and multi-core score of 21645.

In Roblox, the CPU's role is primarily to handle game logic, user-generated script execution, and physics calculations. The measured frame rates, particularly at 1080p, indicate that the CPU is not a limiting factor in most scenarios. At 1080p Low, the system achieves 500 FPS, which is likely near the CPU's practical limit for feeding frames to the GPU. However, the consistent scaling across presets suggests that the CPU can handle the additional draw calls and state changes required by higher settings without becoming a bottleneck.

The CPU's benchmark scores place it in the 83rd percentile of all CPUs, with a Passmark single-thread score of 3701 and a multithread score of 25470. Its performance is closely matched to several rivals, including the AMD Ryzen 7 PRO 8840U (0.1% higher average score), Intel Core i9-11900 (0.2% higher), and AMD Ryzen 7 6800HS (0.2% lower). The i5-14400F's boost clock of 4.70 GHz is particularly beneficial for Roblox's single-threaded workload characteristics, ensuring that the CPU can keep up with the GPU at lower resolutions. The data shows that the CPU has sufficient headroom at higher resolutions, where the GPU becomes the limiting factor, but at 1080p, the CPU's performance directly influences the achievable frame rates, with the 500 FPS ceiling at Low settings representing the practical limit of this combination's processing power.
