Roblox

Measured FPS Breakdown

At 3840x2160, the recorded performance shows a tight band around the 60 FPS target. The Low preset delivers an average of 64 FPS, which is the only 4K setting that clears the playability threshold. Medium averages 59 FPS with a minimum of 50 FPS and a maximum of 67 FPS, placing it just under the 60 FPS line. High drops further to 52 FPS average, while Ultra falls to 42 FPS average. The spread between Low and Ultra at this resolution is 22 FPS, indicating that the graphics preset has a substantial impact on 4K performance.

Moving to 2560x1440, all four presets exceed 60 FPS. Low leads with 114 FPS average, followed by Medium at 104 FPS (minimum 88 FPS, maximum 119 FPS), High at 92 FPS, and Ultra at 74 FPS. The gap between Low and Ultra narrows to 40 FPS, and even the most demanding setting maintains a comfortable margin above the threshold. The Medium preset at 1440p shows a minimum of 88 FPS, which is well above the 60 FPS playability line, suggesting consistent frame delivery without severe dips.

At 1920x1080, performance scales notably higher. Low reaches 171 FPS average, Medium hits 155 FPS (minimum 132 FPS, maximum 179 FPS), High achieves 137 FPS, and Ultra still manages 111 FPS. The difference between Low and Ultra at 1080p is 60 FPS, the largest absolute spread across all resolutions. Even the Ultra preset at 1080p delivers nearly double the 60 FPS threshold, making this resolution the most forgiving for maxed-out settings. The minimum FPS recorded at 1080p Medium is 132, which exceeds the average FPS of some 4K presets, highlighting how resolution scaling affects frame delivery.

CPU and GPU Roles

The data shows a clear pattern where resolution scaling shifts the performance burden. At 1920x1080, the frame rates range from 111 to 171 FPS across presets, which places heavy demand on the CPU's single-core throughput. The Intel Core i7-14700K posts a passmark single-thread score of 4472 and a geekbench single-core score of 2569, both of which are strong indicators for handling game logic at high frame rates. The GPU, Intel Arc B390, sits at the 9th percentile among all GPUs, which suggests it becomes the limiting factor as resolution increases.

At 2560x1440, the average FPS drops by roughly 20 to 25 percent compared to 1080p for each preset. For example, High goes from 137 FPS at 1080p to 92 FPS at 1440p, a reduction of 45 FPS. This scaling indicates that the GPU is beginning to assert its influence, but the CPU still has enough headroom to keep frame rates above 70 FPS even at Ultra. The Arc B390's 3DMark Steel Nomad DX12 score of 1482 places it near the bottom of the database, yet the combination still achieves playable results at 1440p across all settings.

At 3840x2160, the GPU bottleneck becomes dominant. The average FPS at 4K High (52) is nearly half of the 1080p High result (137). Low at 4K only reaches 64 FPS, which is barely above the threshold, while Ultra drops to 42 FPS. The CPU's role diminishes at this resolution because the GPU's rendering throughput, capped by its 7.680 TFLOPS FP32 performance and 24 ROPs, cannot keep pace with the pixel count. The Arc B390's memory bandwidth is system dependent, which further constrains 4K performance. Benchmark results indicate that the i7-14700K is not the limiting factor at any resolution; rather, the GPU dictates the ceiling, with the CPU providing sufficient headroom even at 1080p where frame rates exceed 170 FPS.

How This Combo Ranks

The combination of the Intel Core i7-14700K and the Intel Arc B390 ranks 3289 out of 3711 tested combinations for Roblox. This places the combo in the lower 11th percentile of all systems in the database, which is consistent with the GPU's low individual standing. The Arc B390 ranks at the 9th percentile among all GPUs, while the i7-14700K ranks at the 94th percentile among all CPUs. The pairing of a top-tier processor with a bottom-tier graphics solution creates a significant imbalance, and the overall combo rank reflects the GPU's limitations.

The CPU's nearest rivals in the database include the AMD EPYC 9115 (average score 69288, delta 0.1 percent), AMD Ryzen 9 7950X (average score 69515, delta -0.2 percent), AMD Ryzen 9 7940HX (average score 69875, delta -0.7 percent), and AMD Ryzen 7 9700F (average score 69996, delta -0.9 percent). These processors all perform within 1 percent of the i7-14700K, meaning any of them would produce nearly identical results when paired with the Arc B390 in Roblox. The GPU's nearest rivals are the NVIDIA GeForce GT 520MX (average score 1463, delta 1.3 percent), NVIDIA GeForce 800M (average score 1460, delta 1.5 percent), NVIDIA GeForce GT 625 OEM (average score 1446, delta 2.5 percent), and NVIDIA GeForce GT 710 (average score 1443, delta 2.7 percent). These GPUs are all within 2.7 percent of the Arc B390's average score, indicating that swapping to any of them would yield similar frame rates in this game.

The combo rank of 3289 out of 3711 suggests that while the system can play Roblox, it does so with less headroom than most other configurations. The majority of tested combos outperform this pairing, primarily due to the GPU's weak standing. However, the rank also shows that roughly 422 combos fall below this system, so it is not the absolute floor of the database.

The Verdict

The recorded data confirms that this PC can run Roblox, but the playable resolutions are limited. At 1920x1080, every preset clears the 60 FPS threshold, with Ultra delivering 111 FPS average and Low reaching 171 FPS. This resolution offers full flexibility for users who want maximum visual quality or maximum frame rates.

At 2560x1440, all four presets also remain above 60 FPS. The Ultra preset averages 74 FPS, which is the most demanding setting at this resolution and still provides a 14 FPS margin over the playability line. High averages 92 FPS, Medium averages 104 FPS, and Low averages 114 FPS. For users with 1440p displays, the system can run the game at maximum settings without dropping below the threshold.

At 3840x2160, only the Low preset achieves a playable average of 64 FPS. Medium falls just short at 59 FPS, High drops to 52 FPS, and Ultra bottoms out at 42 FPS. The verdict for 4K is that the system can run Roblox only on Low settings, and even then the margin is slim. Users targeting 4K should expect to sacrifice visual fidelity to maintain smooth gameplay. The playable settings list for each resolution confirms this: 4K allows only Low, while 1440p and 1080p allow all presets.

Similar Performance Alternatives

For the CPU side, the AMD EPYC 9115 is the closest match with an average score 0.1 percent higher than the i7-14700K, making it effectively identical in compute performance. The AMD Ryzen 9 7950X trails by 0.2 percent, the AMD Ryzen 9 7940HX trails by 0.7 percent, and the AMD Ryzen 7 9700F trails by 0.9 percent. Any of these processors would produce imperceptible differences in Roblox frame rates when paired with the same GPU, since the game's performance is GPU-limited at most resolutions.

For the GPU side, the NVIDIA GeForce GT 520MX scores 1.3 percent higher than the Arc B390, making it the nearest comparable option. The NVIDIA GeForce 800M scores 1.5 percent higher, the NVIDIA GeForce GT 625 OEM scores 2.5 percent higher, and the NVIDIA GeForce GT 710 scores 2.7 percent higher. These deltas are small enough that swapping between these GPUs would change average FPS by only a few frames per second in practice. Users with any of these GPUs should expect similar behavior: playable at 1080p and 1440p across all presets, but only Low at 4K.

The database indicates that the CPU has substantial headroom, so upgrading the GPU alone would yield significant gains. Conversely, upgrading the CPU while keeping the Arc B390 would not improve Roblox performance, as the GPU would remain the bottleneck. The nearest rival data suggests that this system is effectively a low-end GPU platform with a high-end CPU, and any comparable GPU in the same performance tier would behave similarly.

Best Settings per Resolution

At 1920x1080, the best settings are Ultra, which averages 111 FPS. This preset provides the highest visual quality available while maintaining a 51 FPS margin above the 60 FPS threshold. Low, Medium, and High also exceed 60 FPS, but Ultra offers the most demanding configuration without sacrificing playability.

At 2560x1440, the best settings are also Ultra, averaging 74 FPS. This is 14 FPS above the threshold, which is sufficient for smooth gameplay. The next step down, High, averages 92 FPS, but Ultra at 74 FPS remains the optimal choice for users prioritizing image quality while staying above 60 FPS.

At 3840x2160, the best settings are Low, averaging 64 FPS. This is the only preset that clears the threshold at 4K. Medium averages 59 FPS, which falls just below the playability line, while High and Ultra are not viable. Users at 4K must accept Low settings to maintain an average above 60 FPS, with only a 4 FPS margin of safety.
