Roblox

Roblox on the AMD Ryzen 9 9900X and Intel Arc B370 is a combination that delivers strong performance at 1080p and 1440p, but falls short of playable at 4K Ultra. The benchmark results show a clear scaling pattern across all settings: 1920x1080, 2560x1440, and 3840x2160. At the 1080p resolution, the measured average frame rates are consistently above 100 FPS across all presets, with the Ultra setting hitting 101 FPS average. Moving to 1440p, the average FPS drops by roughly 20% to 30% depending on the preset, but all four settings remain above the 60 FPS playable threshold. At 4K, the situation changes dramatically: no preset reaches 60 FPS average, and the Ultra setting falls to 38 FPS average. The data shows that this system is well-suited for high-refresh monitors at 1080p, capable of handling Ultra settings at 1440p, but requires a significant reduction in visual quality to approach playability at 4K.

Measured FPS Breakdown

The measured FPS data provides a complete picture of how the Ryzen 9 9900X and Arc B370 handle Roblox across three resolutions and four quality presets. At 1920x1080, the lowest measured average is 101 FPS on Ultra, while the Low preset reaches 154 FPS average. The Medium preset shows a 140 FPS average with a minimum of 119 and maximum of 161, and High sits at 124 FPS average. This resolution is clearly the sweet spot for this combination, as every preset delivers well above the 60 FPS threshold, and even the most demanding setting maintains a comfortable margin.

At 2560x1440, the performance drops are proportional but still strong. The Low preset averages 103 FPS, which is only slightly below the 1080p Low figure. Medium averages 94 FPS with a recorded minimum of 80 and maximum of 108. High averages 83 FPS, and Ultra averages 67 FPS. The 1440p results show that the system can handle the higher pixel count without sacrificing playability, though the Ultra preset at 67 FPS is notably closer to the 60 FPS line than any 1080p result.

At 3840x2160, the performance falls off sharply. Low averages 58 FPS, Medium averages 53 FPS with a minimum of 45 and maximum of 61, High averages 47 FPS, and Ultra drops to 38 FPS. None of these averages clear the 60 FPS threshold, and the Medium preset's maximum of 61 FPS is the only recorded frame rate above playable. The gap between 1440p Ultra (67 FPS) and 4K Ultra (38 FPS) is substantial, a 43% reduction in average frame rate, indicating that the Arc B370's system-shared memory and 25 W TDP limit its ability to push 4K pixel counts.

Best Settings per Resolution

For 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which records a 101 FPS average. This is the clear recommendation for 1080p users who want maximum visual quality without compromising smoothness. The 101 FPS average leaves enough headroom for complex scenes or multiplayer sessions where frame times can vary.

At 2560x1440, the best playable setting is also Ultra, with a 67 FPS average. This is a tighter margin than at 1080p, but it still clears the 60 FPS threshold by a meaningful 7 FPS. The data indicates that 1440p Ultra is playable, though users who prioritize consistent frame rates over visual fidelity might consider High at 83 FPS for more headroom.

At 3840x2160, no preset achieves a 60 FPS average, so there is no best playable setting. The closest option is Low at 58 FPS, which falls short of the playable threshold. Medium at 53 FPS and High at 47 FPS are progressively worse, and Ultra at 38 FPS is not viable for smooth gameplay. The verdict data confirms this, listing no playable settings for 4K.

CPU and GPU Roles

The recorded data reveals that the GPU is the primary bottleneck at higher resolutions, while the CPU remains largely underutilized in this game. The Ryzen 9 9900X is a 12-core, 24-thread processor with a 3DMark max threads score of 13929 and a Cinebench R23 multi-core score of 32172, placing it in the 92nd percentile of all CPUs. Roblox is not a demanding title for such a processor, so the CPU is unlikely to limit frame rates at any resolution.

The scaling between resolutions shows a clear GPU-bound pattern. At 1080p Low, the system averages 154 FPS, which drops to 103 FPS at 1440p Low and 58 FPS at 4K Low. This progression, a 33% drop from 1080p to 1440p and a 44% drop from 1440p to 4K, indicates that the Arc B370's rendering throughput is the limiting factor. The GPU's 6.144 TFLOPS FP32 performance and 48.00 GPixel/s pixel rate are modest figures, and its 5th percentile ranking among all GPUs confirms its entry-level positioning.

The preset scaling further supports this interpretation. At 1440p, the difference between Low (103 FPS) and Ultra (67 FPS) is 36 FPS, a 35% reduction. At 4K, the same preset range spans from 58 FPS to 38 FPS, a 20 FPS difference. The fact that the absolute frame rate drop from preset changes is smaller at 4K than at 1440p suggests that the GPU is already saturated at 4K, and additional visual quality settings have diminishing returns.

The Verdict

Can this PC run Roblox? The answer depends entirely on the target resolution. At 1920x1080, the system runs the game exceptionally well. All four presets, Low, Medium, High, and Ultra, clear the 60 FPS playable threshold, with Ultra averaging 101 FPS. This makes the combination suitable for high-refresh-rate displays at 1080p.

At 2560x1440, the system remains fully playable. The verdict data lists High, Low, Medium, and Ultra as playable settings, with Ultra at 67 FPS being the most demanding option that still works. Users at 1440p can enjoy the game at maximum settings, though the 67 FPS average is close enough to the threshold that some may prefer High at 83 FPS for additional stability.

At 3840x2160, the system cannot maintain 60 FPS on any preset. The verdict data confirms no playable settings at this resolution, with the best option being Low at 58 FPS average. This is a clear limitation of the Arc B370, which is an integrated graphics solution with system-shared memory and a 25 W TDP. The CPU has ample headroom, but the GPU cannot keep up with the pixel workload at 4K.

Overall, this combination is a solid 1080p and capable 1440p gaming setup for Roblox, but it is not suitable for 4K gaming. The combo ranks 3417 out of 3711 tested combinations in the database, reflecting its entry-level GPU performance despite the high-end CPU.

Similar Performance Alternatives

For the CPU, the AMD Ryzen 9 9900X has nearest rivals that perform within a narrow band. The AMD EPYC 9015 scores 57555 on average, which is 0.1% lower than the 9900X's 57498 average benchmark score. The AMD EPYC 7313 scores 57399, 0.2% higher. The Intel Core i9-14900 scores 58115, 1.1% higher, and the Intel Xeon Platinum 8260M scores 58323, 1.4% higher. These four processors would all deliver essentially identical performance in Roblox, as the game is not CPU-intensive and the differences are within a 2.5% band.

For the GPU, the Intel Arc B370's nearest rivals are all older, lower-performance parts. The ATI Mobility Radeon HD 5570 scores 1186, just 0.2% higher than the B370's 1184. The ATI Radeon HD 5770 scores 1190, 0.5% higher. The AMD Radeon HD 7650M scores 1192, 0.7% higher, and the AMD FirePro M2000 scores 1168, 1.4% lower. These comparisons highlight the B370's position as an entry-level integrated solution, with performance similar to discrete GPUs from over a decade ago. Users considering this CPU-GPU pairing should expect frame rates in line with these historical parts, not modern discrete graphics cards.
