Roblox

The AMD Ryzen 7 5700 and NVIDIA GeForce GTX 1650 pairing delivers a highly playable Roblox experience across most resolutions, but the settings you choose matter more than the resolution. The measured data shows this combo ranks 1753 out of 1800 tested combinations, placing it in the lower tier of systems. That ranking undersells the actual frame rates, though, as the game’s modest demands let this hardware produce smooth gameplay. The sweet spot is Medium settings at 1440p, which balances the CPU’s strong multi-threading with the GPU’s 4 GB VRAM limitations.

Settings Recommendations

The data shows a clear hierarchy in performance scaling across presets. At 1080p, Low settings produce 147.9 FPS, Medium drops to 133.8 FPS, High hits 117.6 FPS, and Ultra falls to 94.1 FPS. The gap between Low and Ultra is 53.8 FPS, which is substantial but not crippling. For most players, Medium offers the best experience because it retains visual fidelity while staying above 130 FPS. The step from Medium to High costs only 16.2 FPS, so High remains viable for those prioritizing visuals.

At 1440p, Medium delivers 88.9 FPS, which is still comfortably above 60 FPS. High settings produce 79.4 FPS, and Low hits 99.3 FPS. Ultra sinks to 63.8 FPS, which is borderline for fast-paced gameplay. The data suggests that High is the maximum preset you should use at 1440p if you want a consistent frame rate. At 4K, even Low settings only reach 58.4 FPS, and Medium falls to 47.8 FPS. The 4K row is the only resolution where all presets dip below 60 FPS, so you should avoid it unless you accept sub-60 gameplay.

For the best overall experience, Medium at 1440p is the recommended configuration. It provides 88.9 FPS, which is high enough for smooth motion, and it avoids the VRAM pressure that Ultra settings might create. If you have a 1080p monitor, High settings at 117.6 FPS is the optimal balance, as it looks notably better than Medium while staying well above refresh-rate thresholds.

GPU Role

The GTX 1650 is the limiting factor in this pairing, and the benchmark data confirms its position. The GPU scores 7880 in Passmark G3D and 3048 in Passmark GPU Compute, placing it at the 43rd percentile of all GPUs. Its nearest rivals include the RTX 3050 A Mobile, which scores 8746, and the Radeon 550X, which scores 8749. The GTX 1650 is 0.4% slower than the RTX 3050 A Mobile and 0.4% slower than the Radeon 550X, making it effectively a peer of those parts.

The GPU’s 4 GB of GDDR5 memory operates at 2001 MHz with a 128-bit bus, providing 128.1 GB/s of bandwidth. This VRAM capacity is the primary constraint at higher resolutions. The measured FPS shows that the delta between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low and Ultra is 53.8 FPS, but at 4K it shrinks to 21.1 FPS. That narrowing indicates the GPU is hitting a memory or compute ceiling at 4K, where even reducing settings cannot fully compensate for the pixel load.

The 75 W TDP and lack of power connectors mean this card runs efficiently, but the 2.984 TFLOPS FP32 performance is modest. The texture rate of 93.24 GTexel/s and pixel rate of 53.28 GPixel/s are adequate for Roblox’s blocky geometry but not for heavy post-processing. The data shows that the GPU handles 1080p Ultra at 94.1 FPS, which is respectable, but 4K Ultra at 37.3 FPS is barely playable. The GTX 1650 is a capable 1080p card that struggles at 4K, and the measurements reflect that limitation clearly.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic across all settings, but the pattern reveals where the bottleneck lies. At Low settings, 1080p produces 147.9 FPS, 1440p drops to 99.3 FPS, and 4K falls to 58.4 FPS. That is a 60.4% reduction from 1080p to 4K. At Ultra settings, the progression is 94.1 FPS at 1080p, 63.8 FPS at 1440p, and 37.3 FPS at 4K, a 60.3% reduction.

The consistent percentage drop across presets indicates that the GPU is the dominant constraint. If the CPU were the limiting factor, the FPS would remain similar as resolution increases, because the CPU workload stays constant. Instead, the data shows a steep decline, which means the GTX 1650’s pixel throughput and memory bandwidth are being saturated. The 128.1 GB/s bandwidth is particularly stressed at 4K, where the 4 GB VRAM is also likely exceeded.

The scaling from 1080p to 1440p is more forgiving. At Medium settings, FPS drops from 133.8 to 88.9, a 33.6% reduction. That is a typical penalty for a 77% increase in pixel count. The 1440p to 4K transition is harsher, with Medium dropping from 88.9 to 47.8, a 46.2% reduction. The 4K resolution has 2.25 times the pixels of 1440p, so the steeper drop suggests the GPU is running out of memory bandwidth and VRAM capacity. The data makes it clear that 1440p is the practical ceiling for this combo, with 4K reserved for Low settings if you must use that resolution.

CPU Role

The Ryzen 7 5700 is a strong processor that is not the bottleneck in this configuration. It has 8 cores and 16 threads with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. The 65 W TDP and Zen 3 architecture provide efficient performance. The CPU scores 20655 in Cinebench R23 multi-core and 2916 in single-core, which places it at the 84th percentile of all CPUs. Its average benchmark score of 27220 is 0.7% higher than the Intel Core i9-9900K, which scores 27043.

The CPU’s 16 MB of L3 cache and 51.2 GB/s memory bandwidth are more than sufficient for Roblox, which is not a demanding title. The Passmark multi-thread score of 24303 and integer math score of 90091 indicate that the CPU can handle any background tasks while gaming. The single-thread score of 3296 is particularly relevant, as Roblox typically relies on a few cores for game logic. The data shows that the CPU is never the limiting factor, as the FPS scales inversely with resolution, which is a classic GPU-bound pattern.

The nearest rivals list confirms the CPU’s strong position. The Ryzen 7 5700 is 0.7% ahead of the i9-9900K, 0.8% ahead of the Core i7-12700H, and 1.2% ahead of the Ryzen AI 5 340. These are all capable processors, and the Ryzen 7 5700 holds its own. For Roblox, the CPU’s 8 cores and 16 threads provide plenty of headroom, ensuring that even the most complex user-generated worlds will not cause a CPU bottleneck. The measured FPS at 1080p Low (147.9 FPS) is likely near the game’s engine limit, not the CPU’s.

Measured FPS Breakdown

The complete measured data shows a consistent pattern across all resolutions and settings. At 1920x1080, the lowest preset produces 147.9 FPS, Medium reaches 133.8 FPS, High hits 117.6 FPS, and Ultra falls to 94.1 FPS. The 1080p row is the only one where every preset exceeds 90 FPS, making it the most flexible resolution for this hardware.

At 2560x1440, Low settings deliver 99.3 FPS, Medium produces 88.9 FPS, High achieves 79.4 FPS, and Ultra drops to 63.8 FPS. The 1440p row demonstrates that Medium is the sweet spot, as it stays above 60 FPS with a 15.4 FPS margin over Ultra. The gap between Low and Medium is only 10.4 FPS, so the visual upgrade is nearly free.

At 3840x2160, the performance collapses. Low settings produce 58.4 FPS, Medium falls to 47.8 FPS, High reaches 44 FPS, and Ultra bottoms out at 37.3 FPS. The 4K row is the only one where no preset reaches 60 FPS. The difference between Low and Medium is 10.6 FPS, but the difference between Low and Ultra is 21.1 FPS, showing diminishing returns at this resolution.

The overall trend is clear: this system is best used at 1080p with High or Ultra settings, or at 1440p with Medium settings. The 4K resolution is only viable with Low settings, and even then, the frame rate is below the 60 FPS target. The data indicates that the GTX 1650’s 4 GB VRAM and 128.1 GB/s bandwidth are the limiting factors at higher resolutions, while the Ryzen 7 5700 provides ample CPU headroom. For a smooth Roblox experience, stick to 1080p or 1440p, and let the settings menu do the heavy lifting.
