Roblox

Roblox is a sandbox title that scales across a very wide range of hardware, and the recorded data for this particular combination of an Intel Core i7-14700KF and an Intel Arc B370 shows a clear pattern: the CPU is far more capable than the GPU. The measured frame rates across three resolutions and four quality presets reveal that the system is heavily limited by the graphics component, especially at higher pixel counts. The data indicates that the Arc B370, which sits near the bottom of the GPU performance distribution with a percentile rank of 5, cannot fully utilize the processing power of the i7-14700KF, which ranks in the 94th percentile among all tested CPUs. This imbalance defines the experience at every resolution.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS varies sharply by resolution, according to the recorded measurements. At 1920x1080, the system can run the game at the highest quality preset, Ultra, with an average frame rate of 101 FPS. This is the only resolution where Ultra quality is playable, and it clears the 60 FPS threshold by a comfortable margin. The data also shows that even the High preset at this resolution delivers an average of 124 FPS, while Medium reaches 140 FPS and Low hits 154 FPS, but the Ultra preset is the most demanding option that still qualifies as playable.

At 2560x1440, the best settings that remain at or above 60 FPS is Ultra, with an average frame rate of 67 FPS. This is a smaller margin of safety compared to 1080p, but it is still above the playable threshold. The High preset at this resolution averages 83 FPS, Medium averages 94 FPS, and Low averages 103 FPS, so all four presets are playable, but Ultra is the highest that qualifies.

At 3840x2160, the situation changes completely. The verdict data shows that no settings are playable at this resolution, meaning every preset falls below 60 FPS. The Ultra preset averages only 38 FPS, High averages 47 FPS, Medium averages 53 FPS, and even Low averages 58 FPS. None of these meet the 60 FPS threshold, so the best settings at 4K would be none, as the system cannot maintain playable frame rates at any quality level.

Measured FPS Breakdown

The recorded frame rates show a clear pattern across resolutions and settings. Starting at 1920x1080, the Low preset delivers an average of 154 FPS, which is the highest number in the entire dataset. Medium averages 140 FPS, with a minimum of 119 FPS and a maximum of 161 FPS. High averages 124 FPS, and Ultra averages 101 FPS. All four presets at this resolution are well above the 60 FPS threshold, with even the most demanding preset exceeding 100 FPS.

Moving to 2560x1440, the frame rates drop by a significant margin. Low averages 103 FPS, Medium averages 94 FPS with a minimum of 80 FPS and a maximum of 108 FPS, High averages 83 FPS, and Ultra averages 67 FPS. The gap between Low and Ultra is 36 FPS, which is notable but still leaves every preset above 60 FPS. The minimum reported at Medium is 80 FPS, which remains comfortably playable.

At 3840x2160, the system struggles. Low averages 45 FPS, Medium averages 53 FPS with a minimum of 45 FPS and a maximum of 61 FPS, High averages 47 FPS, and Ultra averages 38 FPS. Notably, the Medium preset shows a maximum of 61 FPS, meaning it occasionally touches the playable threshold, but the average of 53 FPS is below it. The Ultra preset at 4K is the worst result in the entire dataset, averaging only 38 FPS.

The data also shows that frame rate scaling is not linear. Between 1080p and 1440p, the average FPS drops by roughly 30-35% depending on the preset. Between 1440p and 4K, the drop is even steeper, with many presets losing almost half of their 1440p performance. For example, the High preset goes from 83 FPS at 1440p to 47 FPS at 4K, a reduction of 43%. The Ultra preset goes from 67 FPS at 1440p to 38 FPS at 4K, a reduction of 43% as well. This indicates that the GPU is the primary bottleneck at higher resolutions.

Similar Performance Alternatives

Based on the nearest rival data from the database, this combination would behave similarly to a few other configurations. For the CPU, the Intel Core i7-14700KF has an average benchmark score of 70163, and its nearest rivals include the AMD Ryzen 7 9700F, which scores 69996 and is 0.2% slower, the AMD Ryzen 9 7940HX, which scores 69875 and is 0.4% slower, the AMD Ryzen 9 7950X, which scores 69515 and is 0.9% slower, and the Intel Core Ultra 7 265K, which scores 70879 and is 1% faster. These differences are all within 1%, meaning any of these CPUs would produce essentially identical frame rates in Roblox, since the game is not CPU-bound at any resolution in this configuration.

For the GPU, the Intel Arc B580 has an average benchmark score of 1184, and its nearest rivals are the ATI Mobility Radeon HD 5570, with a score of 1186 and 0.2% slower, the ATI Radeon HD 5770, with a score of 1190 and 0.5% slower, the AMD Radeon HD 7650M, with a score of 1192 and 0.7% slower, and the AMD FirePro M2000, with a score of 1168 and 1.4% faster. These deltas are all under 2%, so swapping the Arc B580 for any of these GPUs would result in nearly identical Roblox performance. In practice, the measured FPS at any resolution would be within a few frames per second of the data presented here.

The practical takeaway is that the CPU is not the limiting factor. A user who replaced the i7-14700KF with a Ryzen 7 9700F, Ryzen 9 7940HX, Ryzen 9 7950X, or Core Ultra 7 265K would see no meaningful change in Roblox frame rates, because the GPU is what determines the final numbers. On the GPU side, swapping the Arc B580 for a FirePro M2000 or Radeon HD 5770 would also yield nearly identical results, as the average scores differ by less than 1.5%.

CPU and GPU Roles

The CPU and GPU roles in this game are unbalanced. The Intel Core i7-14700KF is a high-end desktop processor with 20 cores, 28 threads, and a boost clock of 5.60 GHz, and it ranks in the 94th percentile of all CPUs. The Intel Arc B580, on the other hand, is an integrated-class GPU with a 25 W TDP and a percentile of 5th among GPUs. This 89-point percentile gap shows that the CPU is vastly more powerful than the GPU.

The frame rate scaling across resolutions confirms this. At 1920x1080, the system produces an average of 101 FPS at Ultra settings, which is a good result but not exceptional. At 2560x1440, the same Ultra preset drops to 67 FPS, a 34% reduction. At 3840x2160, it drops to 38 FPS, a 62% reduction from 1080p. This steep decline is typical of a GPU-bound scenario, where the GPU's rendering capacity is saturated as pixel count increases. The CPU is not the limiting factor, as the i7-14700KF has plenty of headroom for Roblox's physics and game logic.

The preset scaling within a resolution also shows the GPU's dominance. At 1920x1080, going from Low to Ultra reduces the average FPS from 154 to 101, a 34% penalty. At 2560x1440, the same preset change goes from 103 to 67, a 35% penalty. At 3840x2160, Low to Ultra goes from 45 to 38, a 16% penalty, but all are below 60 FPS anyway. The fact that the relative degradation between Low and Ultra is similar across resolutions suggests the GPU is consistently limiting the frame rate, regardless of how much the CPU is stressed.

At 1080p and 1440p, the CPU is never a limiting factor, as frame rates are high enough to indicate GPU headroom is exhausted. At 4K, the GPU is so far behind that even Low settings cannot reach 60 FPS, which further confirms the GPU bottleneck. If the CPU were the bottleneck, the frame rate would not drop so dramatically when increasing resolution, because the CPU workload per frame is roughly constant. The data shows a steep drop, so the GPU is the primary constraint at all tested resolutions.

The Verdict

The verdict by resolution is straightforward. At 1920x1080, the system is fully playable with all presets, and the best preset that stays at or above 60 FPS is Ultra with an average of 101 FPS. This clears the threshold by a wide margin, so the game runs smoothly even at maximum quality. At 2560x1440, the system is also playable with all four presets, and Ultra is the best preset with an average of 67 FPS, which is above 60 but not by a huge margin. The other presets (High 83 FPS, Medium 94 FPS, Low 103 FPS) all offer higher headroom.

At 3840x2160, the verdict is not playable. No preset stays at or above 60 FPS. The closest is Medium with an average of 53 FPS, but that is 7 FPS short of the playable threshold. The High preset averages 47, Low averages 45, and Ultra averages 38 FPS. The system cannot run Roblox at 4K with playable frame rates at any quality setting.

In summary, the system can run Roblox well at 1080p and 1440p, with 1080p offering the best experience (over 100 FPS at Ultra) and 1440p still being comfortable (67 FPS at Ultra). For 4K, the hardware is insufficient, and the game should be played at a lower resolution to achieve smooth performance. The user would need to lower the resolution to 1440p or below to reach the 60 FPS threshold.

How This Combo Ranks

Within the database of tested combinations, this particular CPU and GPU pair ranks 3417th out of 3711 total combinations. This places it in the lower echelon of all tested combos, at about the 92nd percentile from the bottom. The rank is driven almost entirely by the GPU, because the CPU is in the top 6% of all processors, while the GPU is in the bottom 5%. The combination is, therefore, heavily imbalanced, with the GPU dragging the overall rank down.

The rank of 3417 out of 3711 means that over 90% of all tested combinations perform better than this one. This is expected given the GPU's low benchmark scores. The database shows the Arc B580 has a single 3DMark Steel Nomad DX12 score of 1184, which is an extremely low score, and its percentile of 5th places it below the vast majority of GPUs. In comparison, the CPU's Cinebench R23 multi-core score of 44167 and a 94th percentile shows the CPU is a top-tier part.

For a game like Roblox, which is not graphically demanding, this combination still delivers playable frame rates at 1080p and 1440p, but the overall rank in the database is low because the GPU is a weak component in the grand scheme of all tested hardware. The rank reflects the universal potential of the combo, not just one game. In Roblox specifically, the combo achieves acceptable performance at all resolutions except 4K, but its standing among all 3711 combos is near the bottom, at 3417th place. This implies that while the game runs adequately on this system, the GPU is a significant weak point, and many other configurations would provide higher frame rates or better 4K performance.
