Roblox

Measured FPS Breakdown

The recorded data for Roblox with the AMD Ryzen 5 5500 and Intel Arc B390 shows a wide spread of performance depending on resolution and preset. The measurements cover three resolutions (1920x1080, 2560x1440, 3840x2160) and four settings levels (Low, Medium, High, Ultra). Min and max FPS values were captured only for Medium presets, which provides a useful window into frame pacing at that setting.

At 1920x1080, the system performs strongly across the board. Low settings produce an average of 171 FPS, making this the fastest configuration measured. Medium settings follow at 155 FPS average, with recorded minimums of 132 FPS and maximums of 179 FPS. High settings drop to 137 FPS average, while Ultra still holds at 111 FPS. These numbers indicate that even the most demanding preset at 1080p leaves substantial headroom above the 60 FPS playable threshold, and the gap between Low and Ultra is about 60 FPS, demonstrating that the GPU scales well with reduced load.

Moving to 2560x1440, the averages remain healthy but begin to compress. Low settings hit 114 FPS, Medium averages 104 FPS with min/max of 88 and 119 FPS, High comes in at 92 FPS, and Ultra settles at 74 FPS. The difference between Low and Ultra at this resolution is 40 FPS, smaller than at 1080p, which suggests that resolution scaling is beginning to tax the system. Still, every preset clears the 60 FPS threshold comfortably, and the Medium preset's minimum of 88 FPS indicates stable frame delivery even under load.

At 3840x2160, the picture changes significantly. Low settings average 64 FPS, just above the playable threshold. Medium settings average 59 FPS, with a recorded minimum of 50 FPS and maximum of 67 FPS, meaning the system dips below 60 FPS during demanding scenes. High settings average 52 FPS, and Ultra drops to 42 FPS. These numbers show that 4K resolution is the breaking point for this hardware combination, with only the Low preset maintaining a consistent 60 FPS average, and even that leaves little margin for fluctuation.

The Medium preset at 4K provides the only min/max data for that resolution, and the 50 FPS minimum confirms that frame drops are not hypothetical. The spread between the 67 FPS maximum and 50 FPS minimum indicates variable performance that would be noticeable during gameplay. Across all resolutions, the pattern is consistent: the Arc B390 delivers playable frame rates at 1080p and 1440p with room to spare, but 4K requires significant compromises.

Best Settings per Resolution

For each resolution, the database identifies the most demanding preset that still maintains an average of at least 60 FPS. At 1920x1080, the best settings are Ultra, which runs at 111 FPS average. This is a clear victory for high fidelity gaming, as the system handles the maximum graphical workload without approaching the playability floor. The gap between Ultra and the next lower preset, High at 137 FPS, is 26 FPS, but both are far above the threshold.

At 2560x1440, the best settings are also Ultra, with an average of 74 FPS. This is a tighter margin than at 1080p, but still 14 FPS above the 60 FPS minimum. The data shows that 1440p Ultra is fully playable, and the 74 FPS average provides enough cushion for most scenes. Users who prefer higher frame rates can drop to High at 92 FPS or Medium at 104 FPS, but Ultra remains the recommended ceiling for visual quality without sacrificing smoothness.

At 3840x2160, the situation reverses. The best settings that stay at or above 60 FPS are Low, with an average of 64 FPS. This is the only playable preset at 4K according to the recorded data. Medium falls short at 59 FPS average, and its 50 FPS minimum confirms that it cannot sustain consistent performance. High and Ultra are not viable, averaging 52 and 42 FPS respectively. The recommendation for 4K is clear: if you want to play Roblox at this resolution, you must accept Low settings and even then, the 64 FPS average leaves only a 4 FPS buffer above the threshold.

The verdict data aligns with these findings. For 1920x1080, all four presets are listed as playable, with Ultra as the best choice. For 2560x1440, all four presets are playable, again with Ultra as the best. For 3840x2160, only Low is listed as playable, and it is the best settings option. This progression highlights how the system's performance degrades with resolution, moving from maxed-out settings to minimum settings across the three tiers.

Similar Performance Alternatives

The nearest rivals for the AMD Ryzen 5 5500, based on average benchmark scores, include the AMD Ryzen AI 5 430 with an average score of 19617 and a delta of -0.1 percent, the Intel Core i5-12500 at 19668 and -0.4 percent, the Intel Core i7-10700F at 19499 and 0.5 percent, and the Intel Core i5-11600KF at 19723 and -0.7 percent. These CPUs are all within roughly one percent of the Ryzen 5 5500's average score of 19593, meaning any of them would produce nearly identical frame rates in Roblox. The Ryzen AI 5 430 is essentially a match, while the i5-12500 and i5-11600KF are marginally faster, and the i7-10700F is marginally slower. For practical purposes, a system builder swapping between these processors would see no meaningful difference in gameplay.

The Intel Arc B390's nearest rivals are much older GPUs. The NVIDIA GeForce GT 520MX scores 1463 with a delta of 1.3 percent, the GeForce 800M scores 1460 at 1.5 percent, the GeForce GT 625 OEM scores 1446 at 2.5 percent, and the GeForce GT 710 scores 1443 at 2.7 percent. The Arc B390's average score is 1482, placing it ahead of all four. The performance gaps are small, ranging from 1.3 to 2.7 percent, so these GPUs would behave similarly in Roblox, though the Arc B390 holds a slight edge. The percentile ranking of 9 for the GPU versus 73 for the CPU indicates that the graphics component is the weaker link in this pairing, and users upgrading from any of these rival GPUs would see a modest improvement at best.

The combination of a mid-range CPU and a low-end GPU means that in Roblox, the GPU is likely the primary constraint, especially at higher resolutions. The CPU's rivals are all modern or recent parts with strong multi-threaded scores, while the GPU's rivals are legacy parts from over a decade ago. This mismatch explains why the system performs well at 1080p and 1440p but struggles at 4K.

The Verdict

The recorded data answers the core question directly. This PC can run Roblox, and it does so comfortably at 1920x1080 and 2560x1440. At 1920x1080, all four presets clear 60 FPS, with Ultra averaging 111 FPS. This is a fully playable experience with maximum settings. At 2560x1440, all four presets also clear 60 FPS, with Ultra at 74 FPS. The system is equally playable at this resolution, though the margin shrinks. At 3840x2160, only the Low preset averages 64 FPS, which is above the threshold, but Medium, High, and Ultra all fall below 60 FPS. The verdict is that 4K gaming is possible only with significant visual compromises.

The playable settings lists from the database confirm this. For 1080p, High, Low, Medium, and Ultra are all playable, with Ultra as the best. For 1440p, the same four are playable, again with Ultra as the best. For 4K, only Low is playable, and it is the best settings option at that resolution. The system's performance ceiling is 1440p Ultra, while 4K Low is the absolute limit for smooth gameplay. Users with 1080p or 1440p monitors will have a positive experience, while 4K users will need to adjust expectations or upgrade the GPU.

CPU and GPU Roles

The data reveals how the CPU and GPU divide responsibilities across resolutions and presets. At 1920x1080, the CPU's strength is evident: the Ryzen 5 5500, with its 6 cores and 12 threads, maintains high frame rates even at Low settings (171 FPS), where the GPU is less stressed. The scaling from Low to Ultra at 1080p is 60 FPS, a 35 percent drop, which indicates that the GPU becomes more involved as settings increase, but the CPU still keeps pace. In Roblox, which is often CPU-bound in complex scenes, the Ryzen 5 5500's single-thread score of 836 in 3dmark and 2319 in Cinebench R23 suggests it can handle the game's logic without bottlenecking.

At 2560x1440, the scaling from Low to Ultra is 40 FPS, a smaller absolute drop than at 1080p, but the percentages tell a different story. Low at 114 FPS drops to Ultra at 74 FPS, a 35 percent reduction. The GPU is now the limiting factor, as the increased pixel count demands more from the Arc B390's 7.680 TFLOPS of FP32 performance. The CPU's role diminishes relative to the GPU, but the system remains balanced enough to keep all presets above 60 FPS.

At 3840x2160, the GPU dominates the equation. The scaling from Low to Ultra is 22 FPS (from 64 to 42 FPS), a 34 percent drop, but the absolute numbers are much lower. The Arc B390's 1536 shading units and 24 ROPs are simply not sufficient for 4K at high settings. The CPU's performance is less relevant here because the GPU is overwhelmed. The percentile ranking of 9 for the GPU versus 73 for the CPU reinforces this: the CPU is well above average, while the GPU is near the bottom. In Roblox, the CPU matters most at lower resolutions and lower settings, where it can push high frame rates, but the GPU takes over as the primary constraint at higher resolutions and presets.

The data also shows that the Medium preset, which has min/max values for all resolutions, exhibits the clearest frame pacing differences. At 1080p, the 132 to 179 FPS range indicates a 36 percent variance, which is moderate. At 1440p, the 88 to 119 FPS range is a 35 percent variance, similar. At 4K, the 50 to 67 FPS range is a 34 percent variance, but the lower absolute values make these dips more noticeable. The GPU's role in maintaining minimum frame rates becomes critical at 4K, where the 50 FPS minimum falls below the playable threshold.
