How This Combo Ranks

The Intel Core i7-13700K paired with the Intel Arc B390 lands at rank 3289 out of 3711 tested combos for Roblox. That places this configuration in the lower 11th percentile of all recorded system pairings for this game, which is a striking result given the CPU’s strong overall standing. The processor alone sits at the 89th percentile among all CPUs in the database, but the integrated graphics solution drags the combined experience down considerably. The data indicates that this combo is heavily constrained by the graphics side, and users should expect performance far below what the CPU alone would suggest.

To put the ranking in perspective, the Arc B390’s average benchmark score of 1482 places it at the 9th percentile among all GPUs. That is an extremely low position, and it explains why the combo ranking is so far down the list. The CPU is essentially a top-tier part, while the GPU is an entry-level integrated solution. The mismatch between the two components is stark, and the measured FPS results reflect that imbalance across all resolutions.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i7-13700K is bracketed by several AMD and Intel parts with nearly identical average scores. The AMD Ryzen 9 5900 scores 46,971, which is just 0.2% lower than the i7-13700K’s 46,881. The AMD Ryzen AI 9 HX PRO 375 scores 47,022, a 0.3% difference. On the other side, the AMD Ryzen 9 7845HX and the Intel Xeon w3-2535 both score 46,654, which is 0.5% higher than the i7-13700K. In practice, swapping the i7-13700K for any of these four parts would produce virtually identical CPU-bound behavior in Roblox. The differences are all within one percentage point, well below any perceptible threshold.

For the GPU side, the Arc B390’s nearest rivals are all older NVIDIA parts with similar scores. The GeForce GT 520MX scores 1,463, which is 1.3% higher than the Arc B390’s 1,482. The GeForce 800M scores 1,460, a 1.5% difference. The GeForce GT 625 OEM scores 1,446, which is 2.5% lower, and the GeForce GT 710 scores 1,443, a 2.7% gap. These deltas are small enough that a user moving from any of these GPUs to the Arc B390 would not notice any meaningful difference in Roblox performance. The measured FPS data confirms this, as the Arc B390 struggles at higher resolutions even with the powerful CPU backing it.

CPU and GPU Roles

The recorded data shows a clear pattern: the GPU is the dominant bottleneck in this combination for Roblox, and the CPU’s role diminishes as resolution increases. At 1920x1080, the CPU still has some headroom, but the GPU is already limiting output. At 2560x1440, the GPU load increases, and the CPU matters even less. At 3840x2160, the GPU is fully saturated, and the CPU is largely idle relative to the graphics workload.

Looking at the scaling between resolutions and presets, the evidence is consistent. At 1920x1080 with Low settings, the combo averages 171 FPS. At 2560x1440 Low, that drops to 114 FPS, a 33% reduction. At 3840x2160 Low, it falls to 64 FPS, another 44% reduction. This pattern holds at other presets. The High preset goes from 137 FPS at 1080p to 92 FPS at 1440p, then 52 FPS at 4K. The Medium preset goes from 155 FPS at 1080p to 104 FPS at 1440p to 59 FPS at 4K.

The CPU’s strength is demonstrated by the fact that the i7-13700K has a Cinebench R23 multi-core score of 30,745 and a single-core score of 2,116, which would be overkill for Roblox’s typical thread usage. Even at 1080p, where the CPU has the most influence, the GPU still limits the frame rate to 171 FPS at Low settings, which is far below what a CPU of this caliber could push in less GPU-bound scenarios. At 4K, the CPU becomes almost irrelevant, as even the Low preset only manages 64 FPS average.

The Verdict

The recorded data shows that this PC can run Roblox, but with significant caveats at higher resolutions. At 1920x1080, the system clears the 60 FPS threshold at every preset, including Ultra, which averages 111 FPS. At 2560x1440, the system also clears 60 FPS at all presets, with Ultra averaging 74 FPS. At 3840x2160, the system only clears 60 FPS at the Low preset, which averages 64 FPS. The Medium preset at 4K averages 59 FPS, just missing the 60 FPS target, and High drops to 52 FPS, Ultra to 42 FPS.

The verdict by resolution is straightforward: 1080p and 1440p are fully playable at any visual setting, while 4K is only playable at Low. The database’s playable threshold is 60 FPS, and the 4K Medium preset’s 59 FPS average is a near miss, but it does not meet the threshold. For users with a 4K display, Low settings are the only option to maintain smooth gameplay. For those with 1080p or 1440p displays, the system has enough headroom to run Roblox at maximum quality without concern.

Measured FPS Breakdown

At 1920x1080, the measured FPS values are uniform across all presets. Low runs at 171 FPS average. Medium runs at 155 FPS average, with a minimum of 132 and a maximum of 179. High runs at 137 FPS average. Ultra runs at 111 FPS average. All settings stay well above the 60 FPS threshold, and even the minimum FPS at Medium (132) is more than double the target.

At 2560x1440, the performance drops but remains solid. Low runs at 114 FPS average. Medium runs at 104 FPS average, with a minimum of 88 and a maximum of 119. High runs at 92 FPS average. Ultra runs at 74 FPS average. All presets remain above 60 FPS, with Ultra having the closest margin at 74 FPS average.

At 3840x2160, the GPU bottleneck becomes severe. Low runs at 64 FPS average. Medium runs at 59 FPS average, with a minimum of 50 and a maximum of 67. High runs at 52 FPS average. Ultra runs at 42 FPS average. Only Low clears the 60 FPS threshold. The Medium preset’s minimum of 50 FPS is particularly notable, as it shows significant frame dips even when the average is close to playable.

The data shows that the scaling from 1080p to 1440p is roughly linear, and then the drop to 4K is steep. For example, High at 1080p is 137 FPS, at 1440p it is 92 FPS, and at 4K it is 52 FPS. The Medium preset follows a similar curve: 155, 104, and 59 respectively.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 111 FPS. This is the maximum quality setting available, and the system handles it without issue. The margin is comfortable, 111 FPS is nearly double the playable threshold.

At 2560x1440, the best setting is also Ultra, with an average of 74 FPS. This is above the 60 FPS threshold, but the margin is smaller than at 1080p. Still, the system can run the game at maximum quality at this resolution without dropping below the target.

At 3840x2160, the best setting is Low, with an average of 64 FPS. This is the only preset that clears the 60 FPS threshold at 4K. The Medium preset comes close at 59 FPS average, but it does not meet the requirement. The High and Ultra presets are significantly below playable levels, at 52 and 42 FPS respectively.

For users who prioritize visual quality over resolution, the data suggests that 1440p Ultra is the sweet spot for this combo. For users with 4K displays, the experience is limited to Low settings, which will noticeably reduce the visual fidelity of Roblox. The system does not have the graphics horsepower to handle higher settings at 4K, and the measurement data confirms that the Arc B390 is the limiting factor.
