Roblox

Measured FPS Breakdown

The recorded measurements for this combination cover three resolutions and four quality presets, with average FPS available for all twelve configurations. Minimum and maximum values are only present for the Medium preset at each resolution.

At 1920x1080, the Low preset delivers an average of 171 FPS, which is the highest recorded value across the entire test suite. The Medium preset averages 155 FPS with a minimum of 132 FPS and a maximum of 179 FPS. High settings produce an average of 137 FPS, while Ultra yields 111 FPS. All four presets comfortably exceed the playable threshold of 60 FPS, with even the most demanding setting producing an average roughly 85% above that threshold.

At 2560x1440, the Low preset averages 114 FPS. Medium follows with 104 FPS average, a minimum of 88 FPS, and a maximum of 119 FPS. High settings average 92 FPS, and Ultra produces 74 FPS. The spread from Low to Ultra is 40 FPS, which is proportionally smaller than at lower resolutions, suggesting a growing GPU limitation as resolution increases. Every preset at this resolution stays well above the 60 FPS playable threshold.

At 3840x2160, the picture changes meaningfully. Low settings average 64 FPS, which clears the playability bar but only by a narrow margin of 4 FPS. Medium averages 59 FPS with a minimum of 50 FPS and a maximum of 67 FPS, meaning the average falls just below the 60 FPS threshold. High drops to 52 FPS average, and Ultra falls further to 42 FPS. The spread from Low to Ultra is 22 FPS, and only the Low preset maintains an average at or above 60 FPS.

How This Combo Ranks

In the database rankings for Roblox, this combination ranks 3289 out of 3711 tested combos, placing it in the 88th percentile or worse. That means roughly 89% of tested hardware combinations deliver higher average frame rates in this game. The rank reflects the GPU's modest standing more than the CPU's, since the processor is a high-end desktop part.

The Intel Arc B390 sits at the 9th percentile among all GPUs in the database, which is a very low standing. Its only recorded 3DMark benchmark, Steel Nomad DX12, shows a score of 1482. The CPU, by contrast, ranks at the 84th percentile among all CPUs with an average benchmark score of 35287. This large gap between the CPU percentile and the GPU percentile explains why the combo lands in the lower portion of the overall ranking for Roblox.

The combo rank of 3289 out of 3711 indicates that, while the system can play the game, it does so at frame rates that most tested configurations exceed. The data positions this hardware in the lower performance segment for this specific title, despite the CPU's strong standing.

CPU and GPU Roles

The recorded FPS scaling across resolutions reveals a system that is heavily GPU-bound at 4K and increasingly CPU-tolerant at lower resolutions. Moving from 1920x1080 to 2560x1440, the Ultra preset loses 37 FPS on average (from 111 to 74), and moving from 2560x1440 to 3840x2160, it loses another 32 FPS (from 74 to 42). This steep drop as resolution increases indicates the GPU, with its modest pixel throughput of 60.00 GPixel/s and texture rate of 120.0 GTexel/s, is the limiting factor at higher internal resolutions.

The CPU's influence is more visible at 1920x1080, where the average FPS reaches 171 on Low settings. The Core i7-12700K has strong multi-threaded capability, evidenced by a Cinebench R23 multi-core score of 19784 and a PassMark multithread score of 34404, plus a single-thread PassMark of 4013. These numbers suggest the processor can handle the game's logic and physics easily at lower resolutions.

At 3840x2160, the Low preset averages 64 FPS while Medium drops to 59 FPS. The difference between Low and Medium at 4K is 5 FPS, but the difference between High and Ultra is 10 FPS (52 to 42). This non-linear scaling indicates the GPU's fill rate and shading capacity, with its 7.680 TFLOPS FP32 throughput, become the limiting factor at the highest settings. The GPU uses system shared memory for both capacity and bandwidth, which further constrains performance at high resolutions.

In summary, the CPU is sufficient at all tested settings for this game, but the GPU becomes the bottleneck as both resolution and quality preset increase. The scaling pattern is consistent: every step from Low to Ultra at any given resolution reduces the average FPS, and every resolution step from 1080p to 4K reduces the average FPS for the same preset.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database are all Intel parts with very similar average benchmark scores. The Core i5-13600T averages 35305, which is 0.1% lower than the i7-12700K's average of 35287. The Core i7-12700KF scores 35365, 0.2% higher. The Core i7-13700T scores 35365, also 0.2% higher, and the Core 5 213PE scores 35428, 0.4% higher. The delta percentages are all within 0.4%, meaning any of these CPUs would provide virtually identical performance in Roblox, as the game is not CPU-limited at the tested resolutions.

For the GPU, the nearest rivals are much lower-performing parts. The GeForce GT 520MX has an average score of 1463, which is 1.3% lower than the Arc B390's 1482. The GeForce 800M scores 1460, 1.5% lower. The GeForce GT 625 OEM scores 1446, 2.5% lower, and the GeForce GT 710 scores 1443, 2.7% lower. This indicates that the Arc B390 sits at the very bottom of the GPU performance spectrum, close to legacy low-end parts. In Roblox specifically, these GPUs would likely produce frame rates similar to the Arc B390 at the same settings and resolutions.

The combination of a high-end CPU with a very low-end GPU means that users with any of the nearby CPU alternatives would see essentially identical frame rates to the Core i7-12700K in Roblox, since the GPU is the limiting factor at all resolutions above 1080p with higher presets. Conversely, swapping the Arc B390 for any of the listed rival GPUs would likely reduce performance slightly, given the negative deltas.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which averages 111 FPS. The measured minimum is not recorded for Ultra, but the average is nearly double the threshold, so all presets are playable at this resolution.

At 2560x1440, the most demanding preset that stays at or above 60 FPS is also Ultra, with an average of 74 FPS. The Medium preset provides a minimum of 88 FPS and a maximum of 119 FPS, but Ultra is still safely above the threshold.

At 3840x2160, the only preset that stays at or above 60 FPS is Low, with an average of 64 FPS. Medium averages 59 FPS, which is below the threshold, so it cannot be recommended for smooth 60 FPS gameplay at this resolution.

The Verdict

The data indicates this PC can run Roblox, but with significant limitations at 4K. At 1920x1080, all four presets (Low, Medium, High, Ultra) clear the 60 FPS threshold, with the Ultra preset averaging 111.5 FPS. This is the best experience the hardware can deliver.

At 2560x1440, the situation remains positive: all four presets are playable at 60 FPS or above, with Ultra averaging 74 FPS. Medium provides a minimum of 88 FPS, giving a stable experience even in busy scenes.

At 3840x2160, only the Low preset averages at or above 60 FPS (64 FPS). Medium averages 59 FPS, which is below the threshold, and High and Ultra fall well short at 52 FPS and 42 FPS respectively. The verdict data shows only Low is marked playable at 4K.

The playable threshold is 60 FPS, and the database indicates the best playable settings per resolution: Low at 4K, Ultra at 1440p, and Ultra at 1080p. The system is fully playable at 1080p and 1440p, but at 4K only Low settings provide a smooth experience.
