Measured FPS Breakdown

At 1920x1080, the AMD Ryzen 7 5700 with Intel Arc B370 delivers consistently high frame rates across all presets. Low settings produce an average of 154 FPS, Medium reaches 140 FPS with a minimum of 119 FPS and a maximum of 161 FPS, High sits at 124 FPS, and Ultra still manages 101 FPS. Every preset at this resolution clears the 60 FPS playability threshold by a wide margin, with the gap between Low and Ultra being 53 FPS.

Moving to 2560x1440, the combo remains fully playable at every setting. Low averages 103 FPS, Medium averages 94 FPS with a range of 80 to 108 FPS, High drops to 83 FPS, and Ultra holds at 67 FPS. The scaling from 1080p to 1440p is moderate: Ultra loses 34 FPS, High loses 41 FPS, Medium loses 46 FPS, and Low loses 51 FPS. The minimums at Medium (80 FPS) show that even the lower bound stays comfortably above the 60 FPS target.

At 3840x2160, the picture changes dramatically. No preset reaches the 60 FPS threshold. Low averages 58 FPS, which is just 2 FPS short of playable. Medium averages 53 FPS with a minimum of 45 FPS and a maximum of 61 FPS. High averages 47 FPS, and Ultra falls to 38 FPS. The resolution jump from 1440p to 4K is punishing: Ultra loses 29 FPS, High loses 36 FPS, Medium loses 41 FPS, and Low loses 45 FPS. The 4K data indicates this hardware combination is not suitable for Roblox at that resolution, regardless of settings.

The measured FPS values show a clear pattern: the system is capable of high refresh rates at 1080p, solid 60+ FPS at 1440p, but falls short at 4K. The only recorded minimum and maximum values come from the Medium preset at each resolution, which provides some insight into frame pacing. At 1080p Medium, the 119 FPS minimum versus 161 FPS maximum suggests a 42 FPS spread. At 1440p Medium, the spread narrows to 28 FPS (80 to 108). At 4K Medium, the spread is 16 FPS (45 to 61), indicating tighter frame delivery when the system is more heavily loaded.

Similar Performance Alternatives

The CPU's nearest rivals in the database show that the Ryzen 7 5700 sits in a tightly clustered performance band. The Intel Xeon D-2752TER scores 25,530, just 0.1% higher. The AMD Ryzen 5 6600H scores 25,550, also 0.1% higher. The AMD Ryzen 5 7640U scores 25,485, which is 0.1% lower. The AMD Ryzen 7 5825U scores 25,446, coming in 0.3% lower. These deltas are trivial, meaning any of these processors would deliver nearly identical CPU-bound behavior in Roblox. A system builder swapping the Ryzen 7 5700 for any of these chips would see no meaningful change in frame rates.

The GPU side is where the comparisons become more striking. The Intel Arc B370 has an average benchmark score of 1,184, placing it in the 5th percentile among all GPUs. Its nearest rivals are all older or lower-tier parts. The ATI Mobility Radeon HD 5570 scores 1,186, just 0.2% higher. The ATI Radeon HD 5770 scores 1,190, 0.5% higher. The AMD Radeon HD 7650M scores 1,192, 0.7% higher. The AMD FirePro M2000 scores 1,168, which is 1.4% lower. This cluster indicates that the Arc B370's raw graphics throughput is comparable to a decade-old desktop card or a mid-range mobile GPU from that era. In Roblox, which is not graphically demanding, this level of performance is sufficient for 1080p and 1440p, but the 4K results confirm the GPU is the limiting factor.

CPU and GPU Roles

The data shows that the GPU is the dominant constraint at 4K, while the CPU has enough headroom to keep up at lower resolutions. At 1080p, the difference between Low (154 FPS) and Ultra (101 FPS) is 53 FPS, which is a 34% reduction. At 1440p, the same comparison shows Low at 103 FPS and Ultra at 67 FPS, a 36 FPS difference or 35%. At 4K, Low averages 58 FPS and Ultra averages 38 FPS, a 20 FPS difference or 34%. The percentage drop from Low to Ultra is remarkably consistent across resolutions, which suggests the game's settings scale uniformly regardless of resolution.

However, the resolution scaling tells a different story. From 1080p to 1440p, the average FPS across all settings drops by roughly 35-40%. From 1440p to 4K, the drop is even steeper, around 40-45%. This disproportionate decline at 4K points to the GPU running out of fill rate and shader throughput. The Arc B370 has 1,280 shading units, 40 texture mapping units, and 20 render output units, with a pixel rate of 48.00 GPixel/s and a texture rate of 96.00 GTexel/s. At 4K, the pixel throughput requirement scales to 8.3 million pixels per frame, and the data indicates the GPU cannot sustain 60 FPS even at Low settings.

The CPU side is less stressed. The Ryzen 7 5700 has 8 cores and 16 threads, with a boost clock of 4.60 GHz and 16 MB of L3 cache. Its benchmark scores, such as 20,655 in Cinebench R23 multi-core and 2,916 in single-core, place it well above the requirements for Roblox. The fact that 1080p Low reaches 154 FPS and 1440p Low reaches 103 FPS suggests the CPU is not the bottleneck at these settings. At 4K, the GPU is clearly the limiting factor, as the CPU would be capable of feeding more frames if the GPU could render them.

The verdict data confirms this split. At 4K, no settings are listed as playable. At 1440p and 1080p, all four settings (Low, Medium, High, Ultra) are playable. This binary outcome aligns with the GPU's 5th percentile ranking, which indicates a very low-end part that can handle moderate resolutions but not 4K.

How This Combo Ranks

In the database, this combination of AMD Ryzen 7 5700 and Intel Arc B370 ranks 3,417 out of 3,711 tested combos for Roblox. That places it in the bottom 8% of all tested configurations. The rank reflects the GPU's weak performance, not the CPU's. The Ryzen 7 5700 sits in the 78th percentile among all CPUs, meaning it outperforms 78% of processors in the database. The Arc B370 sits in the 5th percentile among GPUs, meaning it outperforms only 5% of graphics cards.

This disparity creates an unusual situation: a strong CPU paired with a very weak GPU. In Roblox, which is relatively light on CPU demands, the GPU becomes the deciding factor for overall performance. The combo rank of 3,417 out of 3,711 is consistent with the measured FPS data, which shows playable performance at 1080p and 1440p but not at 4K. Many other combos in the database would achieve higher frame rates at 4K, which is why this pairing ranks so low.

The rank also reflects that most tested combos in the database likely include discrete GPUs with more than 1,280 shading units. The Arc B370's integrated-class design, with system-shared memory and a 25 W TDP, is not competitive with even entry-level discrete cards. For Roblox specifically, the game's simple graphics mean the combo can still deliver playable results at 1080p and 1440p, but the overall ranking is dragged down by the 4K failure.

Best Settings per Resolution

At 1920x1080, Ultra settings are the best choice. The average FPS is 101, which provides a comfortable margin above the 60 FPS threshold. The minimum FPS was not recorded for Ultra, but the Medium preset's minimum of 119 FPS suggests the system has substantial headroom.

At 2560x1440, Ultra settings also deliver the best experience. The average FPS is 67, which is 7 FPS above the playable threshold. This is the most demanding preset that remains playable, and it offers the highest visual quality while staying above 60 FPS.

At 3840x2160, no settings are playable. The closest option is Low with an average of 58 FPS, but this is below the 60 FPS threshold. Medium averages 53 FPS, High averages 47 FPS, and Ultra averages 38 FPS. The database lists no playable settings and no best settings for 4K, meaning users should run Roblox at a lower resolution if they want to maintain 60 FPS.
