Settings Recommendations

For Roblox, the measured data shows that the Medium preset delivers the optimal balance of visual fidelity and frame rate across all tested resolutions. At 1920x1080, Medium produces 511 FPS, which is 13% higher than High's 451.1 FPS and 39% higher than Ultra's 368.2 FPS, while still providing a meaningful visual upgrade over Low's 558.9 FPS. The gap narrows at higher resolutions, but Medium remains the standout choice: at 2560x1440 it hits 338.5 FPS versus 299.8 FPS on High and 241.1 FPS on Ultra, and at 3840x2160 it delivers 192.8 FPS compared to 171.8 FPS on High and 138.8 FPS on Ultra.

Ultra is not recommended for this combination. The performance penalty is substantial — at 4K, Ultra drops to 138.8 FPS, which is 28% below Medium and 19% below High. Given that Roblox's visual differences between Medium and Ultra are often subtle in actual gameplay, the frame rate sacrifice is difficult to justify. Low settings are only advisable for competitive play at 1080p, where the 558.9 FPS result provides maximum headroom for high-refresh-rate displays, though the visual downgrade is significant.

The data suggests the RTX 4070 SUPER is never the bottleneck at Medium or below — even at 4K, Medium produces 192.8 FPS, which exceeds most displays' refresh rates. The combination of 12 GB of VRAM and the Ada Lovelace architecture ensures that Roblox's modest asset requirements are trivially satisfied. For users with 144Hz or 165Hz monitors, High at 1440p (299.8 FPS) is the sweet spot for image quality without perceptible frame drops. For 4K display owners, Medium at 3840x2160 (192.8 FPS) is the clear recommendation, as it maintains high refresh rates while keeping visual quality respectable.

How This Combo Ranks

This pairing of AMD Ryzen 7 5700 and NVIDIA GeForce RTX 4070 SUPER ranks 317th out of 1800 tested combinations in Roblox, placing it in the top 18% of all tested systems. This is a strong result, though not exceptional — the ranking reflects that Roblox is not particularly demanding, so even mid-range hardware can achieve high frame rates, and the gap between this combo and top-tier systems is compressed.

The CPU's benchmark performance helps contextualize this ranking. The Ryzen 7 5700 scores 27,220 in average benchmark score, placing it in the 84th percentile of all CPUs. Its nearest rival, the Intel Core i9-9900K, scores 27,043 (a 0.7% difference), and the Intel Core i7-12700H is 0.8% behind at 27,006. This tight clustering means the CPU is competitive with several high-end options from previous generations, which supports the strong combo ranking.

On the GPU side, the RTX 4070 SUPER achieves an average benchmark score of 42,576, also in the 84th percentile. Its nearest rivals include the NVIDIA RTX A6000 (42,653, just 0.2% ahead) and the AMD Radeon RX 7650 GRE (42,723, 0.3% ahead). This near-tie with workstation-class GPUs in synthetic benchmarks is noteworthy, but Roblox's actual frame rates show the 4070 SUPER has ample headroom — the game's rendering demands are far below what this GPU can deliver at maximum load.

The 317th rank out of 1800 combos indicates that while this system is well above average, it is not in the top tier for Roblox specifically. This is expected: Roblox's performance ceiling is often limited by CPU single-thread performance and engine optimization rather than raw GPU power. The data confirms that this combo sits comfortably in the upper quartile, making it a reliable choice for smooth Roblox gameplay at any resolution.

GPU Role

The NVIDIA GeForce RTX 4070 SUPER brings 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. Its base clock runs at 1980 MHz with a boost clock of 2475 MHz, and memory operates at 1313 MHz (21 Gbps effective). The Ada Lovelace architecture includes 7168 shading units, 224 texture mapping units, and 80 ROPs, along with 56 RT cores and 224 tensor cores.

For Roblox, these specifications are overwhelmingly sufficient. The game's blocky aesthetic and relatively simple geometry mean that even at 4K Ultra, the GPU is not pushed to its limits — the measured 138.8 FPS at 3840x2160 Ultra is still well above playable thresholds. The 12 GB VRAM capacity is far beyond Roblox's requirements; the game's textures and asset sizes would not stress even a fraction of this memory pool. The 504.2 GB/s bandwidth provides ample data throughput for the game's draw calls and scene complexity.

The GPU's FP32 performance of 35.48 TFLOPS and pixel rate of 198.0 GPixel/s indicate that the card can handle far more demanding workloads than Roblox presents. The measured frame rates across all settings — from 138.8 FPS at 4K Ultra to 558.9 FPS at 1080p Low — demonstrate that the GPU is never the limiting factor in this combination. Even at 4K Medium, the 192.8 FPS result shows the card has significant headroom, suggesting that Roblox's engine, rather than the GPU, caps performance in certain scenarios.

The RTX 4070 SUPER's 84th percentile ranking among all GPUs, with an average benchmark score of 42,576, reinforces its position as a high-end card. Its nearest rival, the RTX A6000, scores 42,653 (0.2% higher), indicating the 4070 SUPER performs comparably to workstation cards in synthetic tests, though Roblox's real-world performance is more dependent on CPU and engine efficiency.

Measured FPS Breakdown

1920x1080: The performance envelope is exceptionally wide. Low settings produce 558.9 FPS, Medium delivers 511 FPS, High achieves 451.1 FPS, and Ultra drops to 368.2 FPS. The step from Low to Medium costs 47.9 FPS (8.6%), Medium to High costs 59.9 FPS (11.7%), and High to Ultra costs 82.9 FPS (18.4%). The diminishing returns are clear: the jump from High to Ultra sacrifices more performance than any other transition, yet the visual gain is minimal in Roblox's art style.

2560x1440: At 1440p, the same pattern holds but with proportionally lower numbers. Low hits 374.5 FPS, Medium manages 338.5 FPS, High reaches 299.8 FPS, and Ultra falls to 241.1 FPS. The delta between Low and Ultra is 133.4 FPS, representing a 35.6% reduction from Low to Ultra. The transition from Medium to High costs 38.7 FPS (11.4%), while High to Ultra costs 58.7 FPS (19.6%) — again, Ultra is the least efficient setting.

3840x2160: At 4K, the GPU begins to feel some pressure, though results remain high. Low produces 212.5 FPS, Medium achieves 192.8 FPS, High renders 171.8 FPS, and Ultra delivers 138.8 FPS. The gap from Low to Ultra is 73.7 FPS, a 34.7% reduction. Notably, the difference between Medium and High at 4K is 21 FPS (10.9%), which is proportionally similar to lower resolutions, suggesting the GPU still has sufficient headroom to handle the resolution increase without disproportionate scaling penalties.

Across all resolutions, the data shows a consistent hierarchy: Low > Medium > High > Ultra, with Medium offering the best performance-per-visual-fidelity trade-off. The Ultra preset's penalty is consistently the steepest, confirming that it is not optimized for Roblox's rendering needs.

Resolution Scaling

The transition from 1080p to 1440p shows significant frame rate drops across all settings. At Low, 558.9 FPS falls to 374.5 FPS, a 33.0% decrease. Medium drops from 511 to 338.5 FPS (33.8% lower), High from 451.1 to 299.8 FPS (33.5% lower), and Ultra from 368.2 to 241.1 FPS (34.5% lower). This consistent ~33% reduction indicates that the GPU's fill rate and pixel processing are scaling predictably with the 2.25x pixel count increase from 1080p to 1440p.

The 1440p to 4K transition is more revealing. At Low, 374.5 FPS drops to 212.5 FPS, a 43.3% decrease. Medium falls from 338.5 to 192.8 FPS (43.0% lower), High from 299.8 to 171.8 FPS (42.7% lower), and Ultra from 241.1 to 138.8 FPS (42.4% lower). The slightly larger percentage drops at 4K suggest the GPU is beginning to approach its effective limit, though the absolute frame rates remain high.

The scaling pattern indicates that the CPU is the primary limiter at 1080p, while the GPU becomes more relevant at higher resolutions. At 1080p Low, the 558.9 FPS result is likely constrained by the Ryzen 7 5700's single-thread performance (3dmark_single_thread score of 901) rather than the GPU. As resolution increases, the GPU's workload grows, and by 4K, the frame rates reflect a more balanced distribution between CPU and GPU bottlenecks. The fact that 4K Ultra still achieves 138.8 FPS — a playable frame rate — shows that even at maximum settings and resolution, this combo never becomes unplayable.

CPU Role

The AMD Ryzen 7 5700 features 8 cores and 16 threads based on Zen 3 architecture, with a base clock of 3.70 GHz and boost clock of 4.60 GHz. Its 16 MB of L3 cache and 7 nm process node (TSMC) contribute to strong single-threaded performance, as evidenced by its 3dmark_single_thread score of 901 and cinebench_r23_singlecore score of 2916. The CPU's 84th percentile ranking among all processors, with an average benchmark score of 27,220, places it slightly ahead of the Intel Core i9-9900K (27,043, 0.7% behind) and Intel Core i7-12700H (27,006, 0.8% behind).

For Roblox, the CPU's single-thread performance is critical. The game's physics and scripting engine rely heavily on single-core execution, and the Ryzen 7 5700's boost clock of 4.60 GHz provides the necessary headroom. The measured frame rates at 1080p — exceeding 500 FPS on Low and Medium — indicate that the CPU can feed the GPU at very high rates, though the scaling from 1080p to 4K suggests the CPU's influence diminishes as resolution increases.

The passmark_single_thread score of 3296 and passmark_multithread score of 24,303 show a balanced profile: strong single-thread performance for Roblox's engine, with ample multi-thread capability for background tasks or streaming. The 3dmark_16_threads score of 6628 and 3dmark_4_threads score of 3382 indicate that the CPU scales well with thread count, though Roblox rarely utilizes more than a few cores effectively.

The CPU's 65 W TDP and DDR4 memory support (dual-channel, 51.2 GB/s bandwidth) make it an efficient pairing with the RTX 4070 SUPER. The PCIe Gen 3 interface with 20 lanes provides sufficient bandwidth for the GPU, and the Zen 3 architecture's low latency helps maintain consistent frame times. The data shows the CPU is not a bottleneck at any tested resolution, as even 4K Ultra's 138.8 FPS is well above what a CPU-limited scenario would produce.

FAQ

Q: What is the best settings preset for Roblox with this hardware?

A: Medium is the optimal choice across all resolutions. At 1080p it delivers 511 FPS, at 1440p it produces 338.5 FPS, and at 4K it achieves 192.8 FPS — all while providing a significant visual upgrade over Low and avoiding the steep performance penalty of Ultra.

Q: How does this combo rank compared to other tested systems?

A: It ranks 317th out of 1800 tested combinations, placing it in the top 18% of all systems. This reflects the hardware's strong performance, though Roblox's low system requirements compress the ranking gap between mid-range and high-end systems.

Q: Is the RTX 4070 SUPER's 12 GB VRAM sufficient for Roblox?

A: Yes, 12 GB of GDDR6X memory is far more than Roblox requires. The game's asset sizes and texture resolutions do not stress even a fraction of this capacity, as evidenced by the high frame rates at all tested settings, including 4K Ultra at 138.8 FPS.

Q: Why does Ultra settings cause such a large performance drop?

A: The transition from High to Ultra consistently incurs the steepest penalty across all resolutions — 18.4% at 1080p, 19.6% at 1440p, and 19.2% at 4K (368.2 to 368.2 FPS, 241.1 to 138.8 FPS). This suggests Ultra enables rendering features that are inefficient for Roblox's art style, making it the least recommended preset.
