Roblox

Roblox is a sandbox title that scales unusually well across hardware tiers, and the combination of an Intel Core i3-12100F with an NVIDIA GeForce RTX 4080 SUPER produces a dataset that is more revealing about CPU limits than GPU headroom. The measured frame rates show a configuration that is capable of extreme refresh rates at 1080p and 1440p, yet the performance curve indicates that the four-core processor becomes the decisive factor as resolution drops and settings are lowered. This analysis breaks down the measured FPS data, the role of the processor and graphics card, and answers common questions about this pairing.

Resolution Scaling

The measured FPS data shows a clear pattern of diminishing returns as resolution increases, but the shape of that curve is unusual for a high-end GPU. At 1080p with Low settings, the system produces 638.4 FPS. Moving to 1440p Low drops that figure to 425.8 FPS, a reduction of 33%. Stepping up to 4K Low yields 239.4 FPS, which is a further 44% drop from the 1440p result. This steep decline from 1080p to 4K suggests that the rendering load is scaling heavily with pixel count, which is expected for a GPU-bound scenario.

However, the Ultra settings tell a different story. At 1080p Ultra, the average FPS is 417.8. At 1440p Ultra, it falls to 279.6 FPS, a 33% reduction. At 4K Ultra, the average is 154.3 FPS, another 45% drop. The consistency of these percentage drops across settings tiers indicates that the RTX 4080 SUPER is indeed doing most of the work when settings are high, with the pixel throughput being the primary limiter. The data does not show any sign of the CPU bottlenecking the GPU at 4K, as even the lowest settings at 4K remain above 200 FPS.

The more interesting observation is that the gap between Low and Ultra settings shrinks as resolution increases. At 1080p, the difference between Low (638.4 FPS) and Ultra (417.8 FPS) is 220.6 FPS. At 4K, that gap narrows to 85.1 FPS (239.4 vs. 154.3). This compression indicates that at higher resolutions, the GPU's shading and memory bandwidth are saturated, making the visual settings less impactful than the raw pixel workload. The data suggests that for this game, 4K Ultra is the only scenario where the RTX 4080 SUPER is consistently working near its potential, while lower resolutions are increasingly leaving performance on the table due to the CPU.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. Its benchmark scores are modest compared to modern high-core-count parts, with a Cinebench R23 multi-core score of 11912 and a single-core score of 1681. The Geekbench single-core result of 2224 and multi-core of 7413 further characterize it as a part that is strong for its class but limited in absolute throughput. The processor's percentile ranking of 72 among all CPUs places it ahead of the majority of desktop parts, but it sits in a specific performance tier.

The nearest rivals in the CPU benchmark database show how tightly packed this segment is. The i3-12100F has an average benchmark score of 13516, which is 0.1% behind the AMD Ryzen Threadripper PRO 3975WX (13534) and 0.4% ahead of the Intel Core i7-1250U (13462). It also edges out the Intel Core i3-10105 by 0.6% and the Intel Core i7-7700K by 1.8%. This data indicates that the i3-12100F punches well above its core count in synthetic tests, but the measured FPS in Roblox suggests that its four physical cores are the limiting factor in low-resolution, high-refresh scenarios.

In Roblox specifically, the CPU's role is most evident in the 1080p Low result of 638.4 FPS. This number is extraordinarily high, yet it is also the point where the processor is likely hitting its maximum instruction throughput for the game's logic and draw calls. The fact that the 1440p Low result (425.8 FPS) is still above 400 FPS indicates that the GPU is not the bottleneck even at that resolution. The data implies that the i3-12100F can feed the RTX 4080 SUPER enough data to exceed 400 FPS in most settings, but pushing beyond that threshold requires lower resolution and settings that reduce the CPU's per-frame workload. The boost clock of 4.30 GHz helps sustain these high frame rates, but the 4-core limit becomes apparent when comparing to the scaling of the GPU's own capabilities.

Measured FPS Breakdown

The measured FPS data provides a comprehensive picture of performance across three resolutions and four settings tiers. At 1920x1080, the system delivers 514 FPS on High, 580.5 FPS on Medium, 638.4 FPS on Low, and 417.8 FPS on Ultra. The spread between the highest and lowest settings is 220.6 FPS, with Low being the fastest and Ultra the slowest. This ordering is consistent with typical rendering loads, where lower settings reduce pixel shading and texture work.

Moving to 2560x1440, the frame rates remain exceptionally high. High settings produce 342 FPS, Medium produces 389.3 FPS, Low produces 425.8 FPS, and Ultra produces 279.6 FPS. The gap between Low and Ultra narrows to 146.2 FPS, showing that the GPU is becoming more of a factor as the pixel count increases. The 1440p results are all above 270 FPS, which means the RTX 4080 SUPER is still far from being saturated, but the CPU is likely contributing to the diminishing returns compared to 1080p.

At 3840x2160, the performance envelope compresses further. High settings yield 191.5 FPS, Medium yields 222.4 FPS, Low yields 239.4 FPS, and Ultra yields 154.3 FPS. The difference between Low and Ultra is now only 85.1 FPS, indicating that the GPU's shading units and memory bandwidth are the dominant constraints. Notably, the 4K Ultra result of 154.3 FPS is still above the refresh rate of most standard monitors, meaning this configuration can drive 4K at high frame rates without any CPU-induced stutter.

The data also reveals that the scaling from one resolution to the next is not linear. For instance, going from 1080p Ultra (417.8 FPS) to 1440p Ultra (279.6 FPS) is a 33% drop, while going from 1440p Ultra to 4K Ultra (154.3 FPS) is a 45% drop. This non-linear scaling is a direct consequence of the pixel count quadrupling from 1080p to 4K, but only doubling from 1440p to 4K in terms of linear dimensions. The frame rate drops are consistent with the GPU's raw pixel throughput capabilities.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is a high-end Ada Lovelace part with 16 GB of GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth. Its boost clock is 2550 MHz, with a base clock of 2295 MHz. The GPU has 10240 shading units, 320 texture mapping units, and 112 ROPs, which gives it a pixel rate of 285.6 GPixel/s and a texture rate of 816.0 GTexel/s. The FP32 performance is rated at 52.22 TFLOPS, which places it among the most powerful consumer graphics cards available.

In the benchmark database, the RTX 4080 SUPER has an average score of 53610, ranking in the 88th percentile among all GPUs. Its nearest rival, the AMD Radeon RX 6900 XT, has an average score of 53489, a delta of only 0.2%. The RTX 4080 SUPER also leads the AMD Radeon Pro W6600M by 0.4%, the AMD Radeon RX 7700S by 2.1%, and the NVIDIA GeForce RTX 5070 Ti by 2.9%. These margins are small, indicating that the RTX 4080 SUPER is in a tightly contested performance tier.

In Roblox, the GPU's role is primarily to handle the game's rendering pipeline, which includes blocky textures, simple lighting, and character animations. The measured FPS shows that the RTX 4080 SUPER is capable of producing over 150 FPS even at 4K Ultra, which is far beyond what the game's visuals would suggest is necessary. The 16 GB VRAM is unlikely to be a constraint in this title, as Roblox typically does not require large texture pools. The memory bandwidth of 736.3 GB/s is more than sufficient for the game's data throughput, allowing the GPU to maintain high frame rates without memory bottlenecks.

The PassMark G3D score of 34245 and the 3DMark Steel Nomad DX12 score of 6600 further confirm that this GPU is a top-tier performer. However, the measured FPS in Roblox suggests that the GPU is often underutilized, particularly at 1080p where the CPU limits the frame rate. The data shows that the RTX 4080 SUPER can deliver 638.4 FPS at 1080p Low, but this is likely the ceiling imposed by the i3-12100F rather than the GPU's maximum capability. At 4K Ultra, the GPU is more fully engaged, with the 154.3 FPS result being a more representative indicator of its performance in this specific game.
