Roblox

Roblox is a notoriously variable title, but the measured data for this specific pairing of an Intel Core i5-14400F and an Intel Arc B390 reveals a clear and consistent performance hierarchy. The benchmark results show a system that is heavily constrained by its graphics processor, particularly as resolution increases, while the processor's substantial headroom becomes evident at lower resolutions. The data indicates a playable experience across the board, but the journey from 1080p to 4K is marked by significant frame rate drops, underscoring the Arc B390's role as the primary bottleneck in this configuration.

Resolution Scaling

The measured FPS data shows a predictable, yet steep, decline in performance as resolution scales from 1920x1080 up to 3840x2160. At the High preset, the average frame rate drops by 45 FPS when moving from 1080p (137 FPS) to 1440p (92 FPS), a 33% reduction. The scaling from 1440p to 4K is even more punishing, with the average falling a further 40 FPS to just 52 FPS, a 43% drop. This pattern strongly suggests that the Intel Arc B390’s rendering capabilities are being saturated, as the pixel count increase demands more from the GPU's shading units and memory bandwidth.

The trend is consistent across all settings. For instance, the Low preset delivers 171 FPS at 1080p, which drops to 114 FPS at 1440p, and then plummets to 64 FPS at 4K. This represents a 63% total reduction from 1080p to 4K. Similarly, the Ultra preset starts at 111 FPS at 1080p, falls to 74 FPS at 1440p, and bottoms out at 42 FPS at 4K. The fact that even the Low preset cannot maintain a 60+ FPS average at 4K is a strong indicator that the GPU is the limiting component, rather than the CPU. If the processor were the bottleneck, we would expect to see a smaller performance gap between resolutions, as the CPU's workload would remain relatively constant.

The data implies that the game's engine is scaling its graphical load effectively, but the Arc B390's compute resources are insufficient to handle the increased pixel throughput at higher resolutions. The gap between the Low and High presets also widens at higher resolutions, further confirming that the GPU is struggling. At 1080p, the difference between Low and High is 34 FPS (171 vs 137). At 4K, that difference narrows to just 12 FPS (64 vs 52). This compression of frame rates at 4K suggests that the GPU is hitting a hard performance ceiling, where even reducing graphical fidelity yields diminishing returns because the sheer number of pixels is overwhelming the hardware.

How This Combo Ranks

In the grand scheme of tested configurations for Roblox, this combination of the i5-14400F and Arc B390 ranks 2661 out of 3010 combos. This places it in the lower 12th percentile of all tested systems, indicating that while it is fully capable of running the game, it sits well below the performance median. The ranking is a direct consequence of the GPU's limited capabilities, as the CPU is a high-end part that would typically be paired with a much more powerful graphics card in a balanced system.

The combo's rank is a stark contrast to the CPU's own standing. The Core i5-14400F holds an 83rd percentile ranking among all CPUs, showcasing its strong multi-threaded and single-threaded performance. Its average benchmark score of 32279 is nearly identical to its nearest rivals, such as the AMD Ryzen 7 PRO 8840U (32233, a 0.1% difference) and the Intel Core i9-11900 (32226, a 0.2% difference). This indicates that the processor is performing exactly as expected for its class. The weak link is undoubtedly the GPU, which only manages a 9th percentile ranking among all GPUs, with an average score of 1482. Its closest rivals are legacy parts like the NVIDIA GeForce GT 520MX (1463, 1.3% faster) and the GeForce 800M (1460, 1.5% faster), highlighting its position in the lower echelon of graphics hardware performance.

This disparity between the CPU's high percentile and the GPU's low percentile creates an imbalanced system. The data suggests that the i5-14400F is capable of driving much higher frame rates than the Arc B390 can deliver. The combo's low rank in Roblox is not a reflection of the CPU's inadequacy but rather evidence of the GPU's role as the definitive performance limiter. In a game like Roblox, which can be CPU-bound at high frame rates, this pairing leaves significant performance on the table, as the processor is never given the chance to stretch its legs.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and the user's preference for frame rate or visual fidelity. At 1920x1080, the Medium preset offers an excellent balance, delivering an average of 155 FPS with a minimum of 132 FPS. This ensures a smooth and responsive experience that is well above the 144Hz threshold for many monitors. The High preset at 137 FPS is also viable, but the Medium preset provides a more comfortable margin above the 144 FPS mark. The Ultra preset, while visually superior, still delivers a highly playable 111 FPS average, making it a viable choice for those who prioritize graphics.

At 2560x1440, the situation becomes more nuanced. The Medium preset is the clear recommendation, as it maintains an average of 104 FPS with a minimum of 88 FPS, which is still smooth for most gaming scenarios. The High preset at 92 FPS is acceptable, but the frame rate dips closer to 60 FPS territory in demanding scenes. The Low preset at 114 FPS is the only way to get close to a 120Hz experience, but it sacrifices too much visual quality. The Ultra preset, at 74 FPS, is best avoided if a high refresh rate is desired.

The 3840x2160 resolution is where the Arc B390's limitations become most apparent. No preset can maintain a locked 60 FPS, with the Low preset achieving the highest average at 64 FPS. The Medium preset, at 59 FPS, is playable but will experience drops to 50 FPS, which can be noticeable. The High preset at 52 FPS and Ultra at 42 FPS are best reserved for slow-paced or turn-based gameplay. For a consistent experience at 4K, the Low preset is the only sensible choice, as it is the only one that breaks the 60 FPS average threshold, though it will likely dip below it at times.

Measured FPS Breakdown

The following data represents the exact measured average FPS values, with minimum and maximum values provided for the Medium preset where available.

• 1920x1080
• Ultra: Average 111 FPS.
• High: Average 137 FPS.
• Medium: Average 155 FPS (Min 132, Max 179).
• Low: Average 171 FPS.

• 2560x1440
• Ultra: Average 74 FPS.
• High: Average 92 FPS.
• Medium: Average 104 FPS (Min 88, Max 119).
• Low: Average 114 FPS.

• 3840x2160
• Ultra: Average 42 FPS.
• High: Average 52 FPS.
• Medium: Average 59 FPS (Min 50, Max 67).
• Low: Average 64 FPS.

The data shows a clear linear progression: lowering settings always results in a higher average frame rate. The difference between Low and Ultra is 60 FPS at 1080p, 40 FPS at 1440p, and 22 FPS at 4K. This diminishing return on lowering settings at higher resolutions reinforces the GPU bottleneck, as the pixel fill rate becomes the dominant constraint.

GPU Role

The Intel Arc B390 is an integrated graphics processor (IGP) based on the Xe3-LPG architecture. Its performance is anchored by its core configuration of 1536 shading units, 48 texture mapping units (TMUs), and 24 raster output units (ROPs). The GPU operates at a base clock of 300 MHz and can boost up to 2500 MHz. The measured 3DMark Steel Nomad DX12 score of 1482 places it in the 9th percentile of all GPUs, confirming its entry-level performance tier. Its nearest rivals in this benchmark include the NVIDIA GeForce GT 710 (1443, 2.7% slower) and the GeForce GT 625 OEM (1446, 2.5% slower), which are both very old, low-end parts.

A critical factor in this GPU's performance is its memory configuration. The Arc B390 uses "System Shared" memory, meaning it relies on the main system RAM rather than dedicated VRAM. The memory bandwidth is also listed as "System Dependent," which means its performance is heavily influenced by the speed and configuration of the host system's DDR4 or DDR5 memory. This shared memory architecture is likely a significant contributor to the performance drop at 4K, as the GPU has to compete with the CPU for memory bandwidth, and the higher resolution textures and buffers require more data to be transferred.

The GPU's 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate provide a theoretical baseline, but the shared memory bandwidth likely prevents these figures from being fully realized in practice. The data indicates that while the GPU can handle Roblox at modest resolutions and settings, its architecture is not designed for high-resolution gaming. The 12 ray tracing cores and support for DirectX 12 Ultimate are present, but the low raw compute power (7.680 TFLOPS FP32) means these features are unlikely to be usable at playable frame rates in Roblox's more demanding scenes.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. It has a base clock of 2.50 GHz and a boost clock of 4.70 GHz. This processor is a powerhouse in comparison to the GPU. Its Cinebench R23 multi-core score of 21645 and single-core score of 3055 demonstrate its strong performance. The Geekbench scores (11268 multi-core, 2058 single-core) further confirm its capability. This CPU holds an 83rd percentile ranking among all CPUs, with an average benchmark score of 32279. It is effectively tied with the AMD Ryzen 7 PRO 8840U and the Intel Core i9-11900, showing that it performs exactly at the level expected for its class.

In the context of Roblox, the CPU's role is to handle game logic, physics, and draw calls. The measured FPS data suggests that the i5-14400F is more than capable of keeping up with the Arc B390. The fact that frame rates scale so dramatically with resolution and settings indicates that the CPU is not the bottleneck. If the CPU were the limiting factor, the performance would be more consistent across different resolutions, as the CPU's workload would not change significantly when the resolution is adjusted. The 171 FPS at 1080p Low settings shows that the CPU can drive high frame rates, but the GPU cannot sustain them at higher resolutions.

The CPU's large 20 MB shared L3 cache and support for dual-channel DDR4/DDR5 memory are beneficial for gaming. The 16 threads allow for smooth multitasking and handling of background processes while gaming. The data implies that this CPU has significant headroom in Roblox. A more powerful GPU would likely yield substantially higher frame rates, particularly at 1080p and 1440p. The i5-14400F is a balanced mid-range processor that is being held back by the integrated graphics solution it is paired with.
