Roblox

Roblox is a peculiar title for hardware analysis because its visual load is modest, yet its engine can still push frame rates into the hundreds. With the AMD Ryzen 7 3700X and NVIDIA GeForce RTX 2070 SUPER, the measured data shows a system that is overwhelmingly capable of delivering high refresh rates at every preset. The key takeaway from the benchmark results is that this combination is rarely the limiting factor, making the choice of resolution and settings more about display capabilities and consistency than about brute force survival.

Resolution Scaling

The data shows a predictable and steep drop in performance as pixel count increases, but the absolute numbers remain remarkably high. At 1080p High settings, the system averages 269.9 FPS. Moving to 1440p High reduces that to 184.1 FPS, a drop of 85.8 FPS. The jump to 4K High further cuts the average down to 105.1 FPS. This scaling pattern indicates that while the GPU is doing more work, the engine's overhead is still relatively light, allowing the RTX 2070 SUPER to maintain a playable experience even at 4K.

The gap between Low and Ultra settings widens considerably at higher resolutions. At 1080p, the spread from Low (340 FPS) to Ultra (223 FPS) is 117 FPS. At 1440p, that spread narrows to 78.9 FPS (224.9 FPS Low vs. 146 FPS Ultra). At 4K, the spread is 42.9 FPS (127.5 FPS Low vs. 84.6 FPS Ultra). This suggests that at lower resolutions, the CPU has enough headroom to push the GPU to its limits, whereas at 4K, the GPU becomes the primary bottleneck, making the difference between presets less pronounced in absolute FPS but still significant in performance per frame.

The fact that 4K Ultra still produces 84.6 FPS is notable. For a game like Roblox, this means that even the most demanding configuration tested remains comfortably above the 60 FPS threshold. The limiting component at 4K is clearly the GPU, as the CPU's workload does not scale with resolution in the same way. The data indicates that users with 4K displays can use this combination without worrying about playability, though High settings (105.1 FPS) offer a better margin over Ultra for demanding scenes.

Settings Recommendations

For users targeting the highest refresh rates on a 1080p or 1440p display, the Low preset is the clear winner in raw FPS. At 1080p Low, the system reaches 340 FPS, and at 1440p Low, it achieves 224.9 FPS. However, the visual compromise may not be worth the extra frames, especially since Medium settings offer a significant boost in visual quality with a relatively small performance cost. At 1080p, Medium yields 310.1 FPS, which is only 29.9 FPS less than Low. At 1440p, Medium delivers 204 FPS, just 20.9 FPS behind Low.

The data suggests that High settings provide the best balance for most users. At 1440p High, the system produces 184.1 FPS, which is still far above the refresh rate of most high-refresh monitors. At 1080p High, 269.9 FPS is more than enough for even the most competitive 240Hz displays. The jump from High to Ultra incurs a substantial penalty: 46.9 FPS at 1080p (269.9 to 223 FPS) and 38.1 FPS at 1440p (184.1 to 146 FPS). Given that Ultra typically adds minor visual enhancements in Roblox, High is the recommended preset for a smooth experience without sacrificing visual fidelity.

At 4K, the recommendation shifts. High settings (105.1 FPS) provide the best combination of visual quality and performance. Ultra (84.6 FPS) is playable but leaves less headroom for complex scenes. Medium (118.3 FPS) and Low (127.5 FPS) offer higher frame rates but undermine the purpose of a 4K display. The data indicates that High is the sweet spot for 4K, providing a solid 60+ FPS experience with room to spare.

GPU Role

The NVIDIA GeForce RTX 2070 SUPER is the workhorse in this configuration, and the benchmark data shows it has ample power for Roblox. The GPU features 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. For a game like Roblox, which is not known for heavy texture streaming, this memory configuration is more than sufficient. The 4K Ultra result of 84.6 FPS indicates that the GPU is not running out of memory or bandwidth, as performance degrades gracefully rather than hitting a wall.

The clock speeds of the RTX 2070 SUPER are a base of 1605 MHz and a boost of 1770 MHz. The measured FPS suggests that the GPU is able to sustain its boost clock under load, as the performance scaling from 1080p to 4K is consistent with what one would expect from a GPU of this class. The GPU's percentile ranking of 65 places it above the median, and its average benchmark score of 22206 is just slightly below the NVIDIA RTX A400 (22307, -0.5%) and above the AMD Radeon RX 5700 (21670, 2.5%). This confirms that the RTX 2070 SUPER is a solid performer, though not a top-tier card.

The thermal and power profile of the GPU (215 W TDP) suggests that it can run at full tilt without hitting thermal throttling in most systems. The data shows that the GPU is the limiting factor at 4K Ultra, but even then, it delivers a playable frame rate. For users who want to push beyond 4K or use higher refresh rates, the GPU would be the component to upgrade, but for Roblox specifically, it is more than adequate.

Measured FPS Breakdown

At 1920x1080, the system delivers exceptional performance across all presets. Low settings average 340 FPS, Medium 310.1 FPS, High 269.9 FPS, and Ultra 223 FPS. These numbers indicate that the CPU is the primary driver at this resolution, as the GPU is not fully taxed. The difference between Low and Ultra is 117 FPS, showing that users can prioritize visual quality without sacrificing the high refresh rate experience.

Moving to 2560x1440, the performance remains strong. Low settings average 224.9 FPS, Medium 204 FPS, High 184.1 FPS, and Ultra 146 FPS. The drop from 1080p to 1440p is significant, but the frame rates are still high enough for smooth gameplay. The gap between Low and Ultra shrinks to 78.9 FPS, indicating that the GPU is starting to become more relevant.

At 3840x2160, the system shows its limits but remains playable. Low settings average 127.5 FPS, Medium 118.3 FPS, High 105.1 FPS, and Ultra 84.6 FPS. The performance drop from 1440p to 4K is steep, but all presets stay above 84 FPS. The difference between Low and Ultra is only 42.9 FPS, confirming that the GPU is the bottleneck at this resolution. The data shows that even at 4K Ultra, the system can maintain a smooth 60+ FPS experience, which is impressive for a game that is often considered light on hardware.

CPU Role

The AMD Ryzen 7 3700X provides the foundation for this system, and its performance is crucial for the high frame rates seen at 1080p. With 8 cores and 16 threads, the CPU has plenty of multi-threaded capability, but Roblox is often more dependent on single-core performance. The 3700X scores 2694 in Cinebench R23 single-core and 1672 in Geekbench single-core, which are solid numbers for a 2019 processor. The CPU's boost clock of 4.40 GHz helps ensure that game logic and physics are processed quickly.

The CPU's average benchmark score of 28631 places it at the 85th percentile of all CPUs, meaning it outperforms the majority of processors available. Its nearest rivals include the Intel Core i5-12600 (28654, deltaPct -0.1%) and the AMD Ryzen 5 5600XT (28591, deltaPct 0.1%). This shows that the 3700X is still competitive in synthetic benchmarks, though its age is showing against newer parts.

In Roblox specifically, the CPU's role becomes less critical as resolution increases. At 1080p, the CPU is able to feed the GPU with enough data to reach 340 FPS on Low settings. At 1440p and 4K, the GPU takes over as the primary bottleneck. This indicates that the 3700X is more than capable of handling Roblox's workload, and users would not see a significant CPU bottleneck unless they were using a much more powerful GPU. The CPU's 32 MB of L3 cache helps with data-heavy tasks, and its 65 W TDP means it runs cool and efficient, leaving headroom for the GPU to operate at full capacity.
