Roblox

Roblox is a sandbox title that scales unusually well across hardware, and the measured results for the Intel Core i7-12700KF with the NVIDIA GeForce RTX 2070 SUPER confirm this. The data shows a system that is heavily CPU-bound at lower resolutions, with the GPU only becoming a limiting factor at 4K Ultra settings. This combination ranks 1105 out of 1800 tested combos, placing it in the upper half of all configurations for this specific game.

Resolution Scaling

The transition from 1080p to 4K reveals a classic shift in bottleneck behavior. At 1920x1080 with Low settings, the system produces 338.6 FPS, which drops to 225.6 FPS at 2560x1440 and then to 126.8 FPS at 3840x2160. This represents a 27.8% performance reduction when moving from 1080p to 1440p, followed by another 43.8% reduction when moving from 1440p to 4K. The pattern shows that the CPU is the primary driver at lower resolutions, as the frame rate remains extremely high even with the resolution increase.

Looking at High settings, the scaling is similar but slightly less dramatic. The system delivers 274.5 FPS at 1080p, 181.4 FPS at 1440p, and 101.7 FPS at 4K. The percentage drops are 33.9% and 43.9% respectively, indicating that the GPU begins to take on more responsibility as resolution climbs, but the CPU still has headroom to spare. At 4K High, the system maintains over 100 FPS, which is notable for a title that can be demanding in complex scenes.

The Ultra preset tells a different story entirely. At 1080p Ultra, the system produces 221.2 FPS, which falls to 150 FPS at 1440p and then to 81.5 FPS at 4K. The 4K result is the only measured configuration that drops below the 100 FPS threshold, suggesting that the RTX 2070 SUPER's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth become the limiting factors at this resolution and quality level. The gap between 1440p Ultra and 4K Ultra is 45.7%, which is steeper than the equivalent gap at Low settings.

CPU Role

The Intel Core i7-12700KF is a 12-core, 20-thread processor based on the Alder Lake architecture, with a base clock of 3.60 GHz and a boost clock of 5.00 GHz. Its benchmark results place it in the 89th percentile of all CPUs, with an average benchmark score of 35355. The nearest rival, the Intel Core i5-14400, scores 35336, which is only 0.1% behind, while the Intel Core i7-13800H scores 35416, putting the 12700KF 0.2% behind that mobile part.

In Roblox, the CPU's single-thread performance is critical. The processor scores 1043 in 3dmark_single_thread and 4091 in cinebench_r23_singlecore, which are strong results for a desktop part. The 3dmark_2_threads score of 2065 further confirms that even with just two threads active, the processor can sustain high frame rates. This explains why the system achieves 338.6 FPS at 1080p Low — the game is not heavily threaded, and the 12700KF's high boost clock handles the primary game logic without breaking a sweat.

The multi-threaded capabilities are also relevant for background tasks or streaming while playing. The processor scores 28979 in cinebench_r23_multicore and 34092 in passmark_multithread, which means it can handle concurrent workloads without impacting game performance. However, the measured data shows that Roblox itself does not appear to scale with additional cores beyond a certain point, as the frame rate differences between 1080p and 1440p are driven more by resolution than by CPU load. The 3dmark_16_threads score of 9282 and max_threads score of 9983 indicate that the processor has ample headroom for any task Roblox might throw at it.

Settings Recommendations

Based on the measured FPS data, the optimal balance between visual quality and performance is achieved at Medium settings. At 1920x1080 Medium, the system delivers 306.4 FPS, which is only 32.2 FPS lower than Low settings but provides a significant visual improvement. At 2560x1440 Medium, the system produces 205.1 FPS, which is still well above the refresh rate of most high-end monitors. Even at 4K Medium, the system maintains 119.1 FPS, making it a viable option for users with 4K displays.

For users who prioritize maximum visual fidelity, High settings are the next best choice. At 1080p High, the system delivers 274.5 FPS, and at 1440p High, it produces 181.4 FPS. The jump from Medium to High costs roughly 10% of the frame rate at each resolution but adds substantial graphical enhancements. At 4K High, the system still manages 101.7 FPS, which is playable for most users.

Ultra settings should be reserved for users with 1080p or 1440p displays who want the absolute best visuals. At 1080p Ultra, the system delivers 221.2 FPS, and at 1440p Ultra, it produces 150 FPS. However, at 4K Ultra, the frame rate drops to 81.5 FPS, which may feel less smooth in fast-paced scenarios. Given that the gap between Medium and Ultra at 1440p is 55.1 FPS (205.1 vs 150), most users will find Medium or High to be the sweet spot for this configuration.

GPU Role

The NVIDIA GeForce RTX 2070 SUPER is built on the Turing architecture with a TU104 chip manufactured on a 12 nm process. It features 2560 shading units, 160 texture mapping units, and 64 raster output units, along with 40 RT cores and 320 tensor cores. The GPU operates at a base clock of 1605 MHz and a boost clock of 1770 MHz, with 8 GB of GDDR6 memory on a 256-bit bus delivering 448.0 GB/s of bandwidth.

In Roblox, the GPU's role becomes evident at higher resolutions and settings. The measured data shows that at 1080p, the frame rate is nearly identical across Low (338.6 FPS), Medium (306.4 FPS), High (274.5 FPS), and Ultra (221.2 FPS) — the differences are relatively small, suggesting the CPU is the limiting factor. However, at 4K, the spread widens significantly: Low produces 126.8 FPS, Medium produces 119.1 FPS, High produces 101.7 FPS, and Ultra produces 81.5 FPS. This indicates that the GPU's fill rate and memory bandwidth become constraints at 4K.

The GPU's benchmark results support this interpretation. It scores 18169 in passmark_g3d and 7557 in passmark_gpu_compute, placing it in the 65th percentile of all GPUs. Its nearest rival, the NVIDIA RTX A400, scores 22307, which is 0.5% higher, while the NVIDIA GeForce GTX TITAN Z scores 22006, putting the 2070 SUPER 0.9% ahead of that older flagship. The 3dmark_steel_nomad_dx12 score of 1651 shows the GPU can handle modern DirectX 12 workloads, which is relevant for Roblox's evolving rendering engine.

The GPU's 12 nm process node and 13,600 million transistors contribute to a die size of 545 mm², which is large by modern standards but still delivers solid performance. The FP32 throughput of 9.062 TFLOPS and texture rate of 283.2 GTexel/s are sufficient for Roblox's relatively simple geometry, but the 4K Ultra result of 81.5 FPS shows that the GPU is reaching its limits when pushed to maximum quality at high resolution.

Measured FPS Breakdown

The complete measured FPS data for this configuration is as follows:

At 1920x1080, the system delivers 338.6 FPS on Low settings, 306.4 FPS on Medium, 274.5 FPS on High, and 221.2 FPS on Ultra. The spread from Low to Ultra is 117.4 FPS, which represents a 34.7% reduction in performance when moving from the lowest to the highest quality preset. This is the smallest relative spread across all resolutions, confirming that the CPU is the dominant factor at 1080p.

At 2560x1440, the system produces 225.6 FPS on Low, 205.1 FPS on Medium, 181.4 FPS on High, and 150 FPS on Ultra. The spread from Low to Ultra is 75.6 FPS, representing a 33.5% reduction. The absolute frame rates are still very high, with even the Ultra preset exceeding 150 FPS, which is sufficient for high-refresh-rate gaming.

At 3840x2160, the system manages 126.8 FPS on Low, 119.1 FPS on Medium, 101.7 FPS on High, and 81.5 FPS on Ultra. The spread from Low to Ultra is 45.3 FPS, representing a 35.7% reduction. This is the largest relative spread, indicating that the GPU is becoming the primary constraint. The 4K Ultra result of 81.5 FPS is the only measured configuration that falls below 100 FPS, making it the most demanding scenario for this hardware combination.

The scaling from 1080p to 4K shows a consistent pattern across settings. At Low settings, the frame rate drops from 338.6 FPS to 225.6 FPS to 126.8 FPS, representing a 62.5% reduction from 1080p to 4K. At Medium settings, the frame rate drops from 306.4 FPS to 205.1 FPS to 119.1 FPS, a 61.1% reduction. At High settings, the frame rate drops from 274.5 FPS to 181.4 FPS to 101.7 FPS, a 62.9% reduction. At Ultra settings, the frame rate drops from 221.2 FPS to 150 FPS to 81.5 FPS, a 63.2% reduction. These percentages are remarkably consistent, suggesting that the performance scaling is primarily driven by the resolution change rather than the specific quality preset.
