Roblox

Roblox is a notoriously CPU-bound sandbox title, but pairing a 4-core Intel Core i3-12100F with the massive NVIDIA GeForce RTX 5070 creates a distinctive performance profile. The measured data shows a combination that scales predictably with resolution, yet reveals a clear bottleneck shift that defines the experience across all settings.

Resolution Scaling

The FPS drop from 1080p to 4K is severe, indicating that the RTX 5070 is the primary limiting component at lower resolutions, while the i3-12100F becomes increasingly relevant as resolution climbs. At Low settings, the average frame rate falls from 541.9 FPS at 1920x1080 to 360.6 FPS at 2560x1440, a reduction of 33.4%. The gap continues to 4K, where the average drops to 202.4 FPS, which is 62.6% lower than the 1080p figure. This steep decline suggests that the GPU is being pushed harder at higher resolutions, but the CPU still has headroom.

At Ultra settings, the scaling pattern is similar but with lower absolute numbers. The average dips from 355.3 FPS at 1080p to 236.2 FPS at 1440p, then further to 132.8 FPS at 4K. The percentage drop from 1080p to 4K is 62.6%, matching the Low setting trend. This consistency implies that the rendering load scales almost linearly with pixel count, which is typical for a game like Roblox that relies heavily on draw calls and scene complexity. The fact that the 4K Ultra score (132.8 FPS) is still well above playable thresholds indicates that the RTX 5070 has ample raw power, but the i3-12100F’s four cores are likely saturating at these frame rates.

The data reveals an interesting inversion: at 1080p, the difference between Low and Ultra is 186.6 FPS, but at 4K that difference shrinks to just 69.6 FPS. This compression suggests that at lower resolutions, the GPU is not the bottleneck—the CPU is. When resolution increases, the GPU takes on more work, which narrows the performance gap between settings. The measured numbers show that the RTX 5070 is capable of exceeding 500 FPS at 1080p Low, which is far beyond the refresh rate of most monitors, but the i3-12100F may be holding back higher average frame rates.

How This Combo Ranks

The combo ranks 384th out of 1,800 tested combinations in Roblox, placing it in the top 21.3% of all systems. This is a strong position, but it is not exceptional given the caliber of the GPU. The rank suggests that many other CPU-GPU pairings outperform this one in this specific game, likely due to the i3-12100F being a lower-end processor compared to the RTX 5070’s high-end status. The data indicates that the GPU is significantly more powerful than the CPU, which often leads to suboptimal ranking in CPU-bound titles like Roblox.

Looking at the CPU’s own standing, the Intel Core i3-12100F has an average benchmark score of 13,516, which places it in the 72nd percentile of all CPUs. Its nearest rivals include the AMD Ryzen Threadripper PRO 3975WX, which scores 13,534 and is just 0.1% ahead, and the Intel Core i7-7700K, which scores 13,280 and is 1.8% behind. This close grouping indicates that the i3-12100F is competitive with much older or more expensive processors in raw compute, but it lacks the multi-core headroom that many modern games can exploit. The GPU, on the other hand, sits in the 83rd percentile of all GPUs with an average score of 41,687, and is within 0.6% of the NVIDIA GeForce RTX 3090. This comparison highlights the imbalance: the GPU is near the top of its class, while the CPU is merely above average.

The rank of 384 out of 1,800 combos reinforces this disparity. In a game that is heavily dependent on single-threaded performance and low-latency frame generation, the i3-12100F’s 4 cores and 8 threads may be limiting the RTX 5070’s ability to stretch its legs. The measured FPS at 1080p Ultra (355.3 FPS) is still high, but it is not in the upper echelon of scores that the GPU could achieve with a stronger CPU. The data suggests that this combination is well-balanced for high-refresh-rate gaming at 1440p, but it leaves performance on the table at lower resolutions.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. It features 12 MB of shared L3 cache and supports both DDR4 and DDR5 memory. In Roblox, which is known for being heavily dependent on single-core performance, the i3-12100F’s boost clock is critical. Its single-thread benchmark scores are notable: a Geekbench single-core score of 2,224 and a Cinebench R23 single-core score of 1,681. These numbers place it well above many older CPUs, and the data shows that it can handle the game’s physics and logic threads effectively.

However, the core count is a limiting factor. The 3DMark 4-thread score is 2,859, while the 8-thread score is 4,026, indicating that scaling beyond 4 threads yields a 40.8% improvement. This suggests that the CPU can use its Hyper-Threading to some effect, but Roblox may not be optimized to leverage more than a few cores. The Passmark single-thread score of 3,444 and the multi-thread score of 14,015 show a 4.1x difference, which is lower than the ideal 4x scaling from 4 cores, hinting at thermal or power limits. The TDP of 58 W is modest, and the CPU’s 72nd percentile ranking among all processors confirms that it is capable but not top-tier.

In the context of this game, the CPU’s role is to maintain a stable frame delivery pipeline. At 1080p Low, the average FPS of 541.9 suggests that the CPU is almost certainly the bottleneck, as the RTX 5070 could theoretically render far more frames. The boost clock of 4.30 GHz is sufficient to hit these numbers, but the 4-core limit means that any background tasks or game engine overhead could cause frame time spikes. The data shows that the CPU is more than adequate for 60 FPS gaming, but it struggles to keep up with the GPU’s potential at lower resolutions.

Measured FPS Breakdown

At 1920x1080, the average frame rates are exceptionally high across all settings. Low produces 541.9 FPS, Medium yields 495.3 FPS, High delivers 436.7 FPS, and Ultra drops to 355.3 FPS. The difference between Low and Ultra is 186.6 FPS, which is a 34.4% reduction. This indicates that the graphics settings have a meaningful impact on the GPU load, but the CPU is still able to feed frames at a rapid pace. The 1080p numbers are likely limited by the CPU’s ability to process game logic, as the GPU has immense headroom.

Moving to 2560x1440, the averages decrease but remain high. Low produces 360.6 FPS, Medium 331.3 FPS, High 293.4 FPS, and Ultra 236.2 FPS. The drop from 1080p to 1440p is consistent: Low falls by 33.4%, Medium by 33.1%, High by 32.8%, and Ultra by 33.5%. This uniformity suggests that the GPU is now becoming more of a factor, but the CPU is still keeping up. The 1440p Ultra score of 236.2 FPS is still excellent for competitive play, and the data shows no signs of stuttering or frame drops.

At 3840x2160, the averages are the lowest but still highly playable. Low produces 202.4 FPS, Medium 185.5 FPS, High 164.7 FPS, and Ultra 132.8 FPS. The drop from 1440p to 4K is more pronounced: Low falls by 43.9%, Medium by 44.0%, High by 43.8%, and Ultra by 43.8%. This larger percentage drop indicates that the RTX 5070 is now the primary bottleneck, as the pixel count doubles from 1440p to 4K, putting significant strain on the GPU’s memory bandwidth and shading units. The 4K Ultra score of 132.8 FPS is still well above the 60 FPS threshold, demonstrating that this combo can handle 4K gaming without issue, even at maximum settings.

GPU Role

The NVIDIA GeForce RTX 5070 is a powerhouse, built on the Blackwell 2.0 architecture with a 5 nm process from TSMC. It features 6,144 shading units, 192 texture mapping units, and 80 raster output pipelines, along with 48 ray tracing cores and 192 tensor cores. The GPU has 12 GB of GDDR7 memory on a 192-bit bus, delivering a bandwidth of 672.0 GB/s. Its base clock is 2,325 MHz, with a boost clock of 2,512 MHz, and it supports a pixel rate of 201.0 GPixel/s and a texture rate of 482.3 GTexel/s. These specifications are more than sufficient for Roblox, which is not graphically demanding on the GPU side.

The GPU’s benchmark scores confirm its high-end status. It achieves a Passmark G3D score of 29,137 and a Passmark GPU Compute score of 15,787, placing it in the 83rd percentile of all GPUs. Its nearest rival, the NVIDIA GeForce RTX 3090, has an average score of 41,441, which is just 0.6% lower. This close margin indicates that the RTX 5070 offers performance comparable to the previous generation’s flagship, making it an excellent choice for high-resolution gaming. The 3DMark Steel Nomad DX12 score of 5,077 further validates its capability in modern workloads.

In Roblox, the GPU’s role is to render the game’s blocky but increasingly complex scenes. The 12 GB of VRAM is more than enough for any texture pack or user-generated content, and the 672.0 GB/s bandwidth ensures that memory is never a bottleneck. The measured FPS at 4K Ultra (132.8 FPS) shows that the GPU is still delivering high frame rates, but the drop from 1440p indicates that it is working harder. The GPU’s 83rd percentile ranking, combined with the CPU’s 72nd percentile, suggests that the combo is well-matched for 1440p gaming, where the GPU can flex its muscles without being starved by the CPU. The data shows that at 1080p, the GPU is underutilized, as evidenced by the 541.9 FPS Low score, which is likely capped by the CPU’s frame generation limits rather than the GPU’s rendering capability.
