Resolution Scaling

The measured FPS data for Roblox with the AMD Ryzen 9 5950X and NVIDIA GeForce GTX 1650 shows a clear and predictable drop as resolution increases from 1920x1080 to 3840x2160. At 1920x1080 with Low settings, the combo achieves an average of 149.2 FPS. Moving to 2560x1440 on the same settings, the average falls to 97.9 FPS, a reduction of roughly 34%. At 3840x2160, the average drops further to 54.3 FPS, which is about 45% lower than the 1440p result and 64% lower than the 1080p result.

This scaling pattern indicates that the GPU becomes the limiting component as resolution climbs. The GTX 1650's 4 GB of GDDR5 memory and 128-bit bus width, providing 128.1 GB/s of bandwidth, are adequate for 1080p but increasingly strained at higher pixel counts. The frame rate collapse from 149.2 FPS at 1080p Low to 54.3 FPS at 4K Low is steep, showing that the pixel throughput demand outpaces the GPU's raw capabilities. In contrast, the CPU's role diminishes at higher resolutions, as the Ryzen 9 5950X's ample thread count and high boost clock are not the bottleneck here.

The data suggests that for 4K play, even Low settings cannot maintain a smooth 60 FPS, with the average sitting at 54.3 FPS. At 1440p, the situation improves significantly, with Low settings delivering 97.9 FPS and Medium hitting 90.5 FPS, both comfortably above 60 FPS. At 1080p, all settings except Ultra stay above 119.9 FPS, indicating that the GPU is still the primary constraint but has enough headroom for high refresh rate monitors.

GPU Role

The NVIDIA GeForce GTX 1650 is built on the Turing architecture with a TU117 chip, fabricated on a 12 nm process at TSMC. It features 896 shading units, 56 texture mapping units, and 32 raster output units. Its base clock is 1485 MHz, boosting to 1665 MHz, with memory running at 2001 MHz (8 Gbps effective). The GPU's FP32 performance is rated at 2.984 TFLOPS, and its pixel rate is 53.28 GPixel/s with a texture rate of 93.24 GTexel/s.

In Roblox, the GPU's role is evident in the scaling of FPS across settings at a fixed resolution. At 1920x1080, the difference between Low and Ultra settings is 149.2 FPS versus 96.7 FPS, a gap of 52.5 FPS. This indicates that the GPU's shading and texture units are heavily utilized when graphical fidelity increases. The GTX 1650's 4 GB VRAM is a potential limitation for Ultra settings at higher resolutions, though the measured data shows 34.5 FPS at 4K Ultra, which is playable but not smooth.

The GPU's benchmark scores place it in the 43rd percentile among all GPUs, with an average benchmark score of 8713. Its nearest rivals include the NVIDIA GeForce RTX 3050 A Mobile, which scores 8746 (a delta of -0.4%), and the AMD Radeon 550X at 8749 (-0.4%). The GTX 1650 is essentially on par with these competitors, indicating that its performance in Roblox is typical for its class. However, the game's relatively low graphical demands mean that even this modest GPU can deliver playable frame rates at 1080p and 1440p, though 4K remains challenging.

CPU Role

The AMD Ryzen 9 5950X is a 16-core, 32-thread processor based on the Zen 3 architecture, codenamed Vermeer, manufactured on a 7 nm process at TSMC. It has a base clock of 3.40 GHz and a boost clock of 4.90 GHz, with a 64 MB L3 cache. The CPU's benchmark results are strong, with a Cinebench R23 multi-core score of 38607 and a single-core score of 5450. Its Passmark multi-thread score is 45424, and its 3DMark max-threads score is 11597.

In Roblox, the CPU's role is less prominent than the GPU's, as the game is not particularly demanding on processor resources. At 1080p, the FPS difference between Low and Ultra settings is 52.5 FPS, which is primarily due to GPU workload. However, the CPU's high single-core performance (Geekbench single-core score of 2211) ensures that even at 1080p Low, where the GPU is less stressed, the processor can feed frames without becoming a bottleneck. The 149.2 FPS at 1080p Low reflects the CPU's ability to handle game logic and physics efficiently.

The Ryzen 9 5950X sits in the 93rd percentile among all CPUs, with an average benchmark score of 49062. Its nearest rivals include the Intel Core i5-14600K, which scores 49166 (a delta of -0.2%), and the Intel Core i5-14600KF at 49367 (-0.6%). The CPU's multi-threaded capabilities are overkill for Roblox, but they ensure that frame times remain consistent, especially in crowded scenes with many players or complex user-generated content. The data shows that the CPU is not the limiting factor in any resolution or setting combination tested.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of performance across three resolutions and four settings levels. At 1920x1080, the results are as follows: Low averages 149.2 FPS, Medium averages 130.4 FPS, High averages 119.9 FPS, and Ultra averages 96.7 FPS. The drop from Low to Ultra is 52.5 FPS, which is the largest absolute gap among all resolutions, indicating that the GPU is fully utilized at 1080p when settings are maxed out.

At 2560x1440, the averages are: Low at 97.9 FPS, Medium at 90.5 FPS, High at 77.1 FPS, and Ultra at 66.7 FPS. The gap between Low and Ultra here is 31.2 FPS, which is smaller than at 1080p, suggesting that the GPU is becoming more resolution-bound. The step from High to Ultra is only 10.4 FPS, showing diminishing returns for the highest settings.

At 3840x2160, the averages are: Low at 54.3 FPS, Medium at 50.7 FPS, High at 47.4 FPS, and Ultra at 34.5 FPS. The gap between Low and Ultra is 19.8 FPS, and notably, the jump from High to Ultra is 12.9 FPS, which is a significant drop. None of the 4K settings achieve 60 FPS, with Ultra being the only one below 40 FPS. This indicates that 4K is not a viable option for smooth gameplay with this GPU, even on Low settings.

The overall combo rank in Roblox is 1745 out of 1800 combinations, placing it in the lower percentile. This rank reflects the GPU's limitations, as the CPU is highly capable but cannot compensate for the GPU's pixel throughput deficit at high resolutions.

FAQ
