Roblox

The AMD Ryzen 7 9700F paired with the Intel Arc B390 presents a striking contrast in component performance. The CPU is a high-end desktop processor, while the GPU is an integrated graphics solution with a low performance percentile. For Roblox, a game that is often more dependent on single-threaded CPU performance, this pairing yields surprisingly playable results at lower resolutions, but the integrated GPU becomes the limiting factor at higher settings. This analysis breaks down the measured performance data.

Similar Performance Alternatives

The benchmark database places the AMD Ryzen 7 9700F in the 94th percentile of all CPUs, indicating a top-tier processor. Its average benchmark score of 69,996 is nearly identical to several other high-end chips. The closest rival is the AMD Ryzen 9 7940HX, which scores 69,875, a negligible 0.2% difference. The Intel Core i7-14700KF scores 70,163, which is only 0.2% higher than the 9700F. Moving slightly further out, the AMD Ryzen 9 7950X scores 69,515 (0.7% lower) and the Intel Core i7-14700K scores 69,355 (0.9% lower). In practical terms, these four processors would deliver nearly identical frame rates in a CPU-bound scenario, making them all equivalent alternatives for this system.

The situation is quite different for the Intel Arc B390. This integrated GPU sits in the 9th percentile of all GPUs, and its average benchmark score of 1,482 from the 3DMark Steel Nomad DX12 test places it in the company of very old, low-end dedicated graphics cards. Its nearest rival is the NVIDIA GeForce GT 520MX, which scores 1,463, a 1.3% difference. The NVIDIA GeForce 800M scores 1,460 (1.5% higher), the NVIDIA GeForce GT 625 OEM scores 1,446 (2.5% higher), and the NVIDIA GeForce GT 710 scores 1,443 (2.7% higher). For users considering this combo, the data shows that the GPU component will perform on par with these legacy parts, which is a critical consideration for gaming expectations.

CPU and GPU Roles

The measured FPS data reveals a clear division of labor between the CPU and GPU in Roblox. At 1920x1080, the system is largely CPU-bound. The average FPS at Low settings is 171, dropping to 137 at High and 111 at Ultra. This is a 35% reduction from Low to Ultra, but the absolute numbers remain high, indicating that the CPU has enough headroom. The GPU is still able to keep up with the CPU's frame generation at this resolution.

The balance shifts as resolution increases. At 2560x1440, the frame rates drop significantly across all settings. Low settings average 114 FPS, Medium 104 FPS, High 92 FPS, and Ultra 74 FPS. The scaling from 1080p to 1440p at Ultra is a 33% decrease (from 111 to 74 FPS), showing the GPU is starting to become a larger factor. This trend continues at 3840x2160, where the GPU becomes the dominant bottleneck. At 4K, the average FPS for Low settings is 64, Medium is 59, High is 52, and Ultra is a low 42. The difference between 1440p and 4K at Ultra is a 43% drop (from 74 to 42 FPS), confirming that the Arc B390's rendering capacity is the limiting factor at this resolution. The CPU's role is diminished at 4K because the GPU cannot generate frames fast enough to utilize the processor's full potential.

FAQ

Q: Can this PC run Roblox at 1920x1080?

A: Yes, the recorded data shows it can run at all tested presets. The average FPS is 171 at Low, 155 at Medium, 137 at High, and 111 at Ultra, all of which are well above the 60 FPS playable threshold.

Q: What is the best playable setting at 2560x1440?

A: All four settings are playable. The highest quality option that maintains a high frame rate is Ultra, which averages 74 FPS. If aiming for a higher refresh rate, Low settings average 114 FPS.

Q: Is this system capable of 60 FPS at 4K resolution?

A: Only at Low settings, which averages 64 FPS. Medium settings average 59 FPS, just below the threshold, while High and Ultra settings average 52 and 42 FPS, respectively.

Q: How does the CPU compare to the Intel Core i7-14700K?

A: The AMD Ryzen 7 9700F has an average benchmark score of 69,996, which is 0.9% higher than the Intel Core i7-14700K's score of 69,355. The performance difference is minimal.

Q: What kind of GPU performance does the Intel Arc B390 offer?

A: The Intel Arc B390's average benchmark score of 1,482 places it in the 9th percentile of all GPUs. It is most similar to the NVIDIA GeForce GT 520MX, which scores 1,463, a 1.3% difference.

Q: What is the frame rate consistency like at 1920x1080 Medium?

A: The data shows an average of 155 FPS, with a minimum of 132 FPS and a maximum of 179 FPS. This indicates a relatively stable experience with no severe drops.

The Verdict

The recorded data shows that this PC can run Roblox, but the experience is highly dependent on the resolution and quality settings. The verdict by resolution is definitive. At 1920x1080, the system is fully capable, clearing the 60 FPS threshold at all presets, with the best experience at Ultra averaging 111 FPS. At 2560x1440, it also clears 60 FPS at all presets, with Ultra averaging 74 FPS. At 3840x2160, the system only clears the 60 FPS threshold at Low settings, averaging 64 FPS. The data indicates that this is a viable 1080p and 1440p machine for Roblox, but 4K gaming will require compromises, limiting the user to Low settings for a smooth experience.

Measured FPS Breakdown

The following table details the exact average frame rates recorded by resolution and settings.

3840x2160 (4K)

• Low: Average 64 FPS
• Medium: Average 59 FPS, Minimum 50 FPS, Maximum 67 FPS
• High: Average 52 FPS
• Ultra: Average 42 FPS

2560x1440 (1440p)

• Low: Average 114 FPS
• Medium: Average 104 FPS, Minimum 88 FPS, Maximum 119 FPS
• High: Average 92 FPS
• Ultra: Average 74 FPS

1920x1080 (1080p)

• Low: Average 171 FPS
• Medium: Average 155 FPS, Minimum 132 FPS, Maximum 179 FPS
• High: Average 137 FPS
• Ultra: Average 111 FPS

The data shows a clear pattern. At 1080p, the frame rates are high across the board, with the difference between Low and Ultra being roughly 35%. At 1440p, the frame rates are still playable but show a more pronounced drop at higher settings. At 4K, the performance collapses, with only the Low preset managing to stay above the 60 FPS playable threshold. The minimum and maximum values recorded for the Medium preset at each resolution show a variance that suggests the GPU is the primary source of frame time spikes, especially as resolution increases.

How This Combo Ranks

In the database's ranking of tested combinations for Roblox, this specific pairing of the AMD Ryzen 7 9700F and Intel Arc B390 ranks at 3,289 out of 3,711 total combos. This places it in the 11th percentile of all tested systems for this game. This low ranking is almost entirely due to the GPU. While the Ryzen 7 9700F is a top-tier processor, the integrated Arc B390 GPU holds the system back, preventing it from achieving the high frame rates that the CPU is capable of supporting. The data suggests that many other combinations, even those with weaker CPUs, will outperform this setup if they are paired with a more powerful dedicated graphics card. The ranking highlights that this combo is a case of a very strong CPU being paired with a very weak GPU, resulting in a system that is not well-balanced for gaming performance in Roblox.
