Roblox

The AMD Ryzen 7 5700G and NVIDIA GeForce RTX 5090 pairing in Roblox produces an exceptionally high-performing system, ranking in the top 1.1% of all tested combinations. The data shows this combo is overwhelmingly GPU-limited at lower resolutions, with the CPU’s 8-core, 16-thread Zen 3 architecture providing ample headroom for the game’s physics and logic, while the RTX 5090’s massive 32 GB VRAM and 1.79 TB/s bandwidth ensure no visual setting or resolution can stress the graphics subsystem.

CPU Role

The Ryzen 7 5700G is a desktop processor from AMD’s 5000 series, built on the Zen 3 architecture and codenamed Cezanne. It operates with a base clock of 3.80 GHz and a boost clock of 4.60 GHz, providing 8 cores and 16 threads for Roblox’s simulation and scripting workloads. While its single-threaded performance is solid—evidenced by a 3DMark single-thread score of 899 and a Cinebench R23 single-core score of 2930—the benchmark results indicate that Roblox at these settings does not heavily tax the CPU. The processor’s 16 MB of L3 cache and dual-channel DDR4 memory support (with 51.2 GB/s bandwidth) are more than sufficient for the game’s demands.

In this specific configuration, the CPU’s role is to feed the RTX 5090 without becoming a bottleneck. The data suggests it succeeds: at 1080p Low, the system achieves 738.3 FPS, which is remarkably high but still not the theoretical maximum of the GPU. The Ryzen 7 5700G’s passmark multithread score of 24419 and its 83rd percentile ranking among all CPUs indicate robust general processing power. However, compared to the GPU’s 94th percentile ranking, the CPU is the weaker link. This becomes apparent when examining the scaling: from 1080p to 4K, the FPS drop is substantial, showing the GPU is taking over as the primary limiter at higher resolutions. The CPU’s 3DMark 16-thread score of 6629 and 8-thread score of 5648 show it can handle multiple concurrent tasks, but Roblox’s engine appears to leverage only a fraction of this capability, leaving the CPU mostly idle while the GPU works.

GPU Role

The NVIDIA GeForce RTX 5090 is the dominant component in this pairing, built on the Blackwell 2.0 architecture with a 5 nm process. It features a base clock of 2017 MHz and a boost clock of 2407 MHz, with 21760 shading units and 680 tensor cores. The GPU’s 32 GB of GDDR7 memory on a 512-bit bus delivers 1.79 TB/s of bandwidth, which is critical for texture streaming in Roblox’s blocky but increasingly detailed environments. The RTX 5090’s FP32 performance of 104.8 TFLOPS and its 3DMark Steel Nomad DX12 score of 14411 place it in the 94th percentile of all GPUs, and its average benchmark score of 84306 is nearly identical to its nearest rival, the RTX 5090 D, which scores 84241 (a 0.1% delta).

The GPU’s role in Roblox is to render the game’s voxel-based geometry and lighting effects at high frame rates. The data shows it performs exceptionally well: even at 4K Ultra, the system maintains 181.5 FPS, which is far above the refresh rate of most monitors. The RTX 5090’s pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s allow it to handle the game’s draw calls and post-processing effects without strain. In fact, the GPU is so powerful that at 1080p Low, the system reaches 738.3 FPS, which is likely limited by the CPU’s ability to issue draw calls rather than the GPU’s rendering capacity. This is further confirmed by the fact that the GPU’s passmark G3D score of 39650 and OpenCL score of 380114 are among the highest recorded, yet Roblox’s frame rates do not scale linearly with these metrics, indicating a software or CPU-side limit at lower resolutions.

Resolution Scaling

The measured FPS data reveals a clear pattern of CPU limitation at 1080p and GPU limitation at 4K. At 1080p Low, the system hits 738.3 FPS, dropping to 593.2 FPS at High settings and 480.5 FPS at Ultra. Moving to 1440p, the same settings yield 494.1 FPS (Low), 395.5 FPS (High), and 320.4 FPS (Ultra). At 4K, the numbers fall to 278.5 FPS (Low), 225.1 FPS (High), and 181.5 FPS (Ultra). The percentage drop from 1080p to 4K is significant: at Low settings, FPS falls by 62.3% (from 738.3 to 278.5), while at Ultra settings, the drop is 62.2% (from 480.5 to 181.5). This consistency across settings suggests a uniform resolution scaling factor, which is characteristic of a GPU-bound scenario at higher resolutions.

However, the data also shows that the CPU is a limiting factor at 1080p. The difference between 1080p and 1440p at Low settings is 244.2 FPS (from 738.3 to 494.1), a 33.1% drop. This is less than the 43.6% drop from 1440p to 4K (from 494.1 to 278.5), indicating that the GPU is becoming more dominant as resolution increases. In other words, the Ryzen 7 5700G can push Roblox to roughly 700+ FPS at 1080p, but the RTX 5090 is capable of far more, so the system is held back by the CPU at lower resolutions. At 4K, the GPU’s rendering workload becomes the bottleneck, and the system’s frame rates are still extremely high, demonstrating that the RTX 5090 is the stronger component in this pairing.

How This Combo Ranks

This specific combination of the AMD Ryzen 7 5700G and NVIDIA GeForce RTX 5090 ranks 20th out of 1800 tested combos in Roblox, placing it in the top 1.1% of all systems. This ranking is notable because the CPU is not a top-tier processor—it ranks 83rd percentile among all CPUs, with an average benchmark score of 25626. Its nearest rivals include the AMD Ryzen 7 6800U (score 25706, delta -0.3%), Intel Xeon D-2752TER (score 25532, delta 0.4%), and Intel Core 5 210H (score 25490, delta 0.5%). The GPU, however, is near the top of the charts, ranking 94th percentile with an average score of 84306, and its nearest rival, the RTX 5090 D, is only 0.1% apart.

The high combo rank is driven almost entirely by the GPU’s exceptional performance, but the CPU’s adequate single-threaded speed (Cinebench R23 single-core score of 2930) is sufficient to avoid severe bottlenecks. The data shows that this combo outperforms many systems with more balanced CPUs, but it also suggests that a stronger CPU would yield even higher frame rates, particularly at 1080p. The 20th rank out of 1800 indicates that only 19 other combos achieve higher average FPS in Roblox, likely featuring newer or higher-clocked CPUs paired with the same or similar GPUs. This ranking reflects the RTX 5090’s raw power, but it also highlights the Ryzen 7 5700G’s limitations in this specific game.

Settings Recommendations

Based on the measured FPS rows, the optimal settings for this combo depend on the user’s display refresh rate and preference for visual fidelity. At 4K, the Ultra preset delivers 181.5 FPS, which is above 144 Hz and suitable for high-refresh-rate gaming. The Medium preset at 4K offers 253 FPS, a 39.4% increase over Ultra, while the Low preset reaches 278.5 FPS, a 53.4% increase. Given that the visual differences between Medium and Ultra in Roblox are relatively minor, the Medium preset at 4K provides the best balance, offering 253 FPS with a moderate visual boost over Low.

At 1440p, the Ultra preset achieves 320.4 FPS, which is more than enough for any display. The High preset at 395.5 FPS is also excellent, and the Low preset at 494.1 FPS pushes frame rates to extreme levels. For users with 1440p monitors, the High preset is recommended, as it delivers 395.5 FPS while maintaining better visual quality than Low. At 1080p, even the Ultra preset hits 480.5 FPS, so users can max out all settings without concern. However, the data shows diminishing returns: the difference between Medium (667.9 FPS) and High (593.2 FPS) is 74.7 FPS, while the difference between High and Ultra (480.5 FPS) is 112.7 FPS. For competitive play, the Low preset at 1080p offers 738.3 FPS, which minimizes input latency, but for most users, the High preset at 1080p (593.2 FPS) provides an excellent experience with better visuals.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across three resolutions and four settings. At 1920x1080, the Low preset yields 738.3 FPS, Medium yields 667.9 FPS, High yields 593.2 FPS, and Ultra yields 480.5 FPS. The scaling from Low to Ultra at 1080p shows a 34.9% reduction in frame rate, which is relatively modest, indicating that the CPU is the primary limiter here. At 2560x1440, the numbers are 494.1 FPS (Low), 445.7 FPS (Medium), 395.5 FPS (High), and 320.4 FPS (Ultra). The drop from 1080p to 1440p is consistent across settings, averaging around 33%, which is expected as the GPU begins to take on more work. At 3840x2160, the frame rates are 278.5 FPS (Low), 253 FPS (Medium), 225.1 FPS (High), and 181.5 FPS (Ultra). The drop from 1440p to 4K is steeper, averaging around 44%, confirming that the GPU is the dominant factor at 4K.

The data also reveals interesting patterns in settings scaling. At 1080p, the difference between Low and Ultra is 257.8 FPS, while at 4K, the difference is 97 FPS. This shows that the impact of settings increases as resolution decreases, because the CPU is more likely to be the bottleneck at lower resolutions, and higher settings add GPU load that the RTX 5090 can easily absorb. At 4K, the GPU is already heavily loaded, so the relative impact of settings is smaller. The Ultra preset at 4K (181.5 FPS) is the lowest measured result, but it is still far above playable thresholds, demonstrating the exceptional capability of this combo.
