Roblox

The pairing of AMD’s Ryzen 5 7500F with NVIDIA’s GeForce RTX 4070 produces extraordinary frame rates in Roblox, a sandbox title where the CPU often dictates performance ceilings. The measured data shows this combination ranks 449th out of 1800 tested combos for this game, placing it in the top quartile of all systems. With average frame rates ranging from 121.8 FPS at 4K Ultra to 501.3 FPS at 1080p Low, this configuration is capable of driving high-refresh-rate displays even at demanding resolutions. The following analysis breaks down how resolution, processor, and graphics card each contribute to these results, offering practical guidance for optimizing the experience.

Resolution Scaling

The frame rate progression across resolutions reveals a clear pattern of CPU limitation at lower settings and GPU influence at higher ones. At 1080p Low, the system delivers 501.3 FPS, which drops to 337 FPS at 1440p Low and 192.1 FPS at 4K Low. This represents a 38% reduction from 1080p to 1440p and another 43% reduction from 1440p to 4K, showing that even at Low settings, resolution scaling has a substantial impact. The gap between 1080p and 1440p Low is 164.3 FPS, while the 1440p to 4K gap is 144.9 FPS, indicating that the GPU begins to assert more influence as pixel count rises.

Moving to High settings, the pattern shifts. The system produces 405.7 FPS at 1080p, 266.9 FPS at 1440p, and 154.6 FPS at 4K. The percentage drop from 1080p to 1440p is 34%, nearly identical to Low settings, but the drop from 1440p to 4K is 42%, slightly less than at Low. This suggests that the RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are sufficient to handle the increased texture loads, but the core clock scaling from 1920 MHz base to 2475 MHz boost becomes more critical at 4K.

The most telling data point is the Ultra preset. At 1080p Ultra, the system hits 330 FPS, which drops to 216.5 FPS at 1440p and 121.8 FPS at 4K. The 4K Ultra result is less than half of the 1080p Low figure, demonstrating that the most demanding settings place significant strain on the GPU. The delta between Low and Ultra at 4K is 70.3 FPS, while at 1080p the delta is 171.3 FPS. This narrowing gap at higher resolutions indicates that the CPU’s ability to feed frames becomes less of a bottleneck, allowing the GPU’s 29.15 TFLOPS FP32 throughput and 46 RT cores to become the limiting factor.

CPU Role

The AMD Ryzen 5 7500F is a 6-core, 12-thread processor based on the Zen 4 Raphael architecture, manufactured on a 5 nm process. Its base clock of 3.70 GHz boosts to 5.00 GHz, and benchmark results show strong single-thread performance: a 3DMark single-thread score of 974 and a Cinebench R23 single-core score of 3218. This single-thread capability is crucial for Roblox, which typically relies on one or two primary threads for game logic and physics. The CPU’s 32 MB of shared L3 cache and dual-channel DDR5 memory support with 83.2 GB/s bandwidth provide ample data throughput for the game’s asset streaming.

The processor’s multi-threaded scores are equally robust, with a Cinebench R23 multi-core score of 22799 and a Passmark multithread score of 26825. However, the game’s frame rates at 1080p Low (501.3 FPS) versus 1080p Ultra (330 FPS) suggest that the CPU is not fully saturated even at the highest settings. The fact that 1080p High (405.7 FPS) is 24% higher than 1080p Ultra (330 FPS) indicates that the GPU is doing more work at Ultra, but the CPU still has headroom. The Ryzen 5 7500F ranks in the 82nd percentile among all CPUs, with an average benchmark score of 24993. It sits just 0.1% ahead of the Intel Core i7-11850H and 0.4% ahead of the AMD Ryzen 9 6900HX, while trailing the Ryzen 7 2700X by 0.3%.

At 4K Ultra, the frame rate drops to 121.8 FPS, which is still above 120 FPS for high-refresh displays. The CPU’s 5.00 GHz boost clock and 6 physical cores are sufficient to keep up with the GPU’s output, as evidenced by the relatively small performance gap between 1440p and 4K at High settings (112.3 FPS difference) compared to the 1080p to 1440p gap (138.8 FPS). This indicates that the Ryzen 5 7500F is not the primary constraint at higher resolutions, allowing the RTX 4070 to shine.

Settings Recommendations

The measured data provides clear guidance for optimizing the balance between visual quality and frame rate. At 1080p, the Low preset delivers 501.3 FPS, which is excessive for most displays, while Medium offers 458.7 FPS and High drops to 405.7 FPS. The Ultra preset at 330 FPS is still exceptionally high, making it the recommended choice for 1080p users who prioritize image quality over raw speed. The step from High to Ultra costs 75.7 FPS, but the visual improvements in a sandbox title like Roblox are often worth the trade-off for players with 144Hz or 240Hz monitors.

For 1440p, the story changes slightly. High settings yield 266.9 FPS, which is still well above 240Hz refresh rates, while Ultra produces 216.5 FPS. The Medium preset offers 305.3 FPS, providing a middle ground for those who want maximum smoothness. The data suggests that High is the sweet spot at 1440p, as it offers 50.4 FPS more than Ultra while maintaining a 19% performance advantage over the most demanding preset. Low at 1440p (337 FPS) is only 12% faster than High, indicating diminishing returns from lowering settings.

At 4K, the recommendations shift toward lower presets. Ultra produces 121.8 FPS, which is borderline for 120Hz displays, while High offers 154.6 FPS and Medium reaches 172 FPS. Low at 192.1 FPS is the only preset that comfortably exceeds 144Hz. For 4K users, High provides the best balance, delivering 32.8 FPS more than Ultra while maintaining visual fidelity. The jump from High to Medium adds 17.4 FPS, which may be noticeable on 144Hz panels, but the visual compromise is significant. Players with 60Hz displays can safely use Ultra, as even the lowest 4K result of 121.8 FPS is double the refresh rate.
