# Roblox Performance Analysis: AMD Ryzen 7 5700X3D + NVIDIA GeForce RTX 4070 SUPER

This combination of an AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 4070 SUPER delivers exceptional performance in Roblox, with measured frame rates ranging from 136.8 FPS at 4K Ultra to 558 FPS at 1080p Low. The data shows a system that is overwhelmingly GPU-limited at higher resolutions while becoming increasingly CPU-bound at 1080p, where the processor's 96 MB of shared L3 cache and 3.00 GHz base clock with 4.10 GHz boost become the primary throughput drivers. The RTX 4070 SUPER's 12 GB of GDDR6X memory on a 192-bit bus with 504.2 GB/s bandwidth provides ample headroom for Roblox's blocky geometry and texture workloads, while the CPU's 8 cores and 16 threads based on Zen 3 architecture at the 7 nm process node handle the game's simulation and scripting logic with considerable margin.

Resolution Scaling

The measured FPS data reveals a clear pattern of resolution-dependent scaling that shifts the performance bottleneck between components. At 1920x1080 with Low settings, the system achieves 558 FPS, which drops to 508.5 FPS at Medium, 447.5 FPS at High, and 363.6 FPS at Ultra settings. This represents a 34.8% reduction from Low to Ultra at 1080p, indicating that even at the lowest resolution, settings increases impose meaningful workload growth on the rendering pipeline. Moving to 2560x1440, the Low preset yields 376.9 FPS, Medium produces 340.7 FPS, High achieves 301.2 FPS, and Ultra delivers 241.6 FPS. The transition from 1080p to 1440p at the Low preset shows a 32.5% frame rate reduction, which suggests the GPU is beginning to take on more responsibility but the CPU still has substantial headroom.

At 3840x2160, the scaling becomes more pronounced. Low settings produce 211.7 FPS, Medium reaches 191.4 FPS, High drops to 171.6 FPS, and Ultra falls to 136.8 FPS. The 1080p Low to 4K Low transition represents a 62.1% decrease in frame rate, while the same resolution change at Ultra settings shows a 62.4% drop. This consistent scaling pattern across all settings presets indicates that the RTX 4070 SUPER is the limiting component at 4K, as the pixel throughput requirements outpace the CPU's ability to feed the GPU with enough draw calls. The 220 W TDP GPU with a boost clock of 2475 MHz and 7168 shading units must process four times the pixel count of 1080p, and the data confirms this workload scales predictably with resolution.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER plays the dominant role in determining Roblox's frame rates at higher resolutions, with its memory subsystem and clock speeds directly influencing the measured results. The GPU's 12 GB of GDDR6X memory operates at 1313 MHz with a 21 Gbps effective data rate, delivering 504.2 GB/s of bandwidth across a 192-bit bus. Roblox's asset streaming and world generation benefit from this memory capacity, as the game's procedurally generated environments can accumulate substantial texture and mesh data during extended play sessions. The 35.48 TFLOPS FP32 compute throughput and 554.4 GTexel/s texture rate provide ample raw processing power for the game's relatively simple shader workloads.

The GPU's 56 RT cores and 224 tensor cores are largely idle in Roblox, as the game does not utilize ray tracing or DLSS features in the measured configurations. However, the base clock of 1980 MHz and boost clock of 2475 MHz allow the GPU to maintain high utilization across all tested settings. The measured FPS data shows that at 4K Ultra, the GPU sustains 136.8 FPS, which is still well above typical display refresh rates, indicating that the RTX 4070 SUPER is never fully saturated even at the most demanding tested configuration. The pixel rate of 198.0 GPixel/s and texture rate of 554.4 GTexel/s suggest the GPU could handle even higher workloads, but Roblox's engine limitations and CPU overhead at lower resolutions prevent the GPU from being the primary constraint below 1440p.

How This Combo Ranks

The combination of the AMD Ryzen 7 5700X3D and NVIDIA GeForce RTX 4070 SUPER ranks 342 out of 1800 tested combinations in Roblox, placing it in the top 19% of all tested systems. This ranking reflects the strong synergy between the CPU's 96 MB of shared L3 cache, which is particularly beneficial for Roblox's frequent cache-miss-heavy workloads, and the GPU's high memory bandwidth and compute throughput. The CPU's average benchmark score of 24673 places it in the 82nd percentile among all processors, with its nearest rival being the Intel Core i7-1360P at 24627 (0.2% higher) and the AMD Ryzen 5 7600X3D at 24605 (0.3% higher). This indicates the 5700X3D is well-matched to the GPU's capabilities, providing enough single-threaded performance for Roblox's primary game thread while maintaining strong multi-threaded throughput for background tasks.

The GPU's average benchmark score of 42576 places it in the 84th percentile among all graphics cards, with its nearest rival being the NVIDIA RTX A6000 at 42653 (-0.2% difference) and the AMD Radeon RX 7650 GRE at 42723 (-0.3% difference). The close proximity of these scores suggests the RTX 4070 SUPER is competitively positioned within the GPU hierarchy, but its 12 GB memory capacity and 504.2 GB/s bandwidth provide advantages for Roblox's specific workload characteristics. The combination's rank of 342 out of 1800 systems indicates that while many higher-end configurations exist, this pairing delivers exceptional frame rates that exceed the requirements of virtually all display setups, with even the lowest measured result of 136.8 FPS at 4K Ultra being well above the 60 FPS threshold for smooth gameplay.

Measured FPS Breakdown

At 1920x1080, the system achieves its highest frame rates across all settings. The Low preset produces 558 FPS, Medium delivers 508.5 FPS, High reaches 447.5 FPS, and Ultra drops to 363.6 FPS. The gap between Low and Ultra at this resolution is 194.4 FPS, representing a 34.8% performance penalty for maximum visual quality. The 1080p results indicate that the CPU is the primary limiter, as the frame rates exceed what the GPU's pixel throughput would suggest is possible, and the scaling between settings is relatively modest compared to higher resolutions.

At 2560x1440, the measured frame rates remain exceptionally high but show increased GPU involvement. Low settings produce 376.9 FPS, Medium achieves 340.7 FPS, High delivers 301.2 FPS, and Ultra reaches 241.6 FPS. The transition from 1080p to 1440p at corresponding settings shows reductions of 32.5% for Low, 33.0% for Medium, 32.7% for High, and 33.6% for Ultra. This consistent scaling across settings suggests the GPU is becoming the limiting factor, as the pixel count increase of 77.8% from 1080p to 1440p is partially absorbed by the GPU's headroom.

At 3840x2160, the frame rates remain playable but show the most significant GPU impact. Low settings yield 211.7 FPS, Medium produces 191.4 FPS, High achieves 171.6 FPS, and Ultra drops to 136.8 FPS. The reduction from 1440p to 4K shows decreases of 43.8% for Low, 43.8% for Medium, 43.0% for High, and 43.4% for Ultra. This near-uniform scaling across all settings confirms that the GPU is the sole bottleneck at 4K, with the RTX 4070 SUPER's compute and memory resources determining the achievable frame rates.

Settings Recommendations

For users with 1080p displays, the Ultra preset at 363.6 FPS provides the best visual experience while maintaining frame rates that exceed the refresh rate of virtually all gaming monitors. The High preset at 447.5 FPS offers a marginal frame rate improvement but sacrifices some visual fidelity, while the Medium preset at 508.5 FPS and Low preset at 558 FPS provide diminishing returns for competitive play scenarios where maximum responsiveness is prioritized. Given that Roblox's visual enhancements at Ultra settings include improved lighting and shadow quality, the 194.4 FPS difference between Low and Ultra at 1080p is unlikely to be perceptible on standard 144 Hz or 240 Hz displays.

For 1440p users, the Ultra preset at 241.6 FPS remains well above the refresh rate of most high-refresh monitors, making it the recommended choice for visual quality without compromising smoothness. The High preset at 301.2 FPS and Medium preset at 340.7 FPS offer additional headroom for users with 360 Hz displays or those who prefer maximum frame rate consistency. The Low preset at 376.9 FPS provides the highest possible frame rate but sacrifices visual quality that may be noticeable on larger displays.

At 4K resolution, the High preset at 171.6 FPS represents the optimal balance between visual quality and performance, as it provides a substantial improvement over the Ultra preset's 136.8 FPS while maintaining the visual enhancements that make the game more immersive at this resolution. The Medium preset at 191.4 FPS and Low preset at 211.7 FPS are viable alternatives for users with high-refresh 4K displays, but the Ultra preset should be avoided unless the user prioritizes maximum visual fidelity over frame rate. The data shows that this combination can handle Roblox at any resolution and settings level, with even the most demanding configuration exceeding 136 FPS, making this system effectively future-proof for the game's current performance requirements.
