# Roblox with Intel Core i5-12400F + NVIDIA GeForce RTX 4070 SUPER

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4070 SUPER delivers extraordinary frame rates in Roblox, a sandbox title from 2006 that scales impressively on modern hardware. This combination ranks 345th out of 1,800 tested combos in this game, placing it in the top 19% of all systems evaluated. The data shows a system that is dramatically overprovisioned for Roblox's typical workloads, with even the most demanding 4K Ultra settings producing frame rates far above display refresh rates. The benchmark results indicate a pairing where the CPU, with its 6 cores and 12 threads from Intel's Alder Lake architecture, and the GPU, built on TSMC's 5 nm process with 35,800 million transistors, both contribute to a seamless experience across all resolution and settings combinations.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, though the magnitude of that degradation is surprisingly modest given the game's age and graphical simplicity. At 1080p Low settings, the system produces 561.7 FPS, while at 4K Low settings it drops to 213.9 FPS — a reduction of 347.8 FPS, or roughly 62% lower. This steep decline indicates that at lower resolutions, the system is overwhelmingly CPU-bound, with the RTX 4070 SUPER's 35.48 TFLOPS of FP32 compute sitting largely idle while the i5-12400F's single-thread performance (2,332 in Cinebench R23 single-core) becomes the limiting factor.

The scaling from 1440p to 4K tells a more nuanced story about the GPU's role. At High settings, the system delivers 298.6 FPS at 1440p and 167.4 FPS at 4K — a 131.2 FPS drop that suggests the GPU is becoming increasingly involved. However, the RTX 4070 SUPER, with its 12 GB of GDDR6X memory and 504.2 GB/s bandwidth, still has enormous headroom. The transition from 1080p Ultra (366 FPS) to 4K Ultra (135.9 FPS) represents a 230.1 FPS reduction, yet even the 4K Ultra figure remains nearly three times the refresh rate of a standard 60 Hz display.

The pattern across all settings levels indicates that Roblox is not a GPU-intensive workload for this hardware. The largest absolute FPS gap between 1080p and 4K occurs at Low settings (347.8 FPS difference), while the smallest occurs at Ultra settings (230.1 FPS difference). This inverted scaling — where lower settings show larger FPS drops with resolution increases — confirms that the game's rendering pipeline, not the GPU's raw compute capacity, determines the performance ceiling. The RTX 4070 SUPER's 7168 shading units and 224 texture mapping units are vastly underutilized in this title.

How This Combo Ranks

The combo's position at 345 out of 1,800 tested combinations places it well within the upper quartile of all systems evaluated for Roblox. This ranking reflects the strength of both components individually: the i5-12400F sits at the 77th percentile among all CPUs in the database, while the RTX 4070 SUPER ranks at the 84th percentile among all GPUs. When combined, these components produce a system that outperforms the vast majority of alternatives, though the game's low system requirements mean that even mid-range hardware can achieve playable frame rates.

The CPU's nearest rivals in aggregate benchmark scores include the Intel Core i7-8700K, which scores 19,210 versus the i5-12400F's 19,221 — a negligible 0.1% difference. The AMD Ryzen 5 7533HS trails by 0.7% with a score of 19,364, while the AMD EPYC 7773X leads by 1.3% at 18,979. These tight margins indicate that the i5-12400F's 10 nm process node and Alder Lake architecture deliver competitive single-threaded and multi-threaded performance against both older and newer designs. The 3DMark scores reinforce this: 5,895 in the 16-thread test and 909 in single-thread, showing strong scaling from 2 threads (1,699) to 8 threads (4,779).

On the GPU side, the RTX 4070 SUPER's average benchmark score of 42,576 places it just 0.2% behind the NVIDIA RTX A6000 (42,653) and 0.3% behind the AMD Radeon RX 7650 GRE (42,723). It leads the AMD Radeon Pro 580X by 1.4% and the NVIDIA Tesla M40 by 1.6%. This clustering around the 42,000-score mark suggests that the RTX 4070 SUPER delivers performance comparable to much more expensive workstation and data-center cards, at least in the synthetic benchmarks recorded. The Geekbench Vulkan score of 179,271 and OpenCL score of 192,684 further demonstrate substantial compute capability that Roblox simply does not tax.

CPU Role

The Intel Core i5-12400F plays a critical role in this system's Roblox performance, despite the game being primarily GPU-accelerated. With 6 cores and 12 threads running at a 2.50 GHz base clock and 4.40 GHz boost clock, this Alder Lake-S processor provides substantial single-threaded headroom — a key requirement for a game engine that often processes game logic and rendering commands on a limited number of threads. The Cinebench R23 scores of 2,332 single-core and 16,518 multi-core indicate a balanced design that excels at both lightly-threaded and heavily-threaded workloads.

The 18 MB of shared L3 cache, along with 1.25 MB of L2 cache per core and 80 KB of L1 cache per core, helps reduce memory latency in a game that frequently accesses small, frequently-reused data structures. The dual-channel memory controller supporting both DDR4 and DDR5 provides flexibility, though the measured FPS figures suggest that memory bandwidth is not a limiting factor in Roblox. The Passmark scores for integer math (59,995) and floating-point math (46,759) show strong arithmetic throughput, while the 23,327 score in data compression and 11,679 in data encryption indicate robust general-purpose processing capability.

The CPU's influence is most evident in the scaling from Low to Ultra settings at each resolution. At 1080p, the jump from Low (561.7 FPS) to Ultra (366 FPS) represents a 34.8% reduction, while at 4K the same settings change reduces performance from 213.9 FPS to 135.9 FPS — a 36.5% reduction. This consistent percentage drop across resolutions suggests that the CPU is setting the performance floor, with the GPU's additional work at higher settings and resolutions not fundamentally changing the bottleneck characteristics. The 3DMark 2-thread score of 1,699 and 4-thread score of 3,067 indicate that even with only a few active threads, the processor maintains strong performance — critical for Roblox's often single-threaded physics and scripting workloads.

Measured FPS Breakdown

At 1920x1080, the system achieves its highest frame rates across all settings. Low settings produce 561.7 FPS average, Medium settings deliver 507.5 FPS, High settings reach 450.9 FPS, and Ultra settings maintain 366 FPS. The progression from Low to Ultra shows a consistent decline, with the largest single-step drop occurring between Medium and High (56.6 FPS) and the smallest between Low and Medium (54.2 FPS). These figures indicate that even at 1080p Ultra, the system maintains frame rates that exceed the refresh rate of virtually all gaming monitors.

Moving to 2560x1440, the performance remains exceptionally high. Low settings average 371.3 FPS, Medium settings 337.8 FPS, High settings 298.6 FPS, and Ultra settings 241.7 FPS. The percentage reduction from the corresponding 1080p figures ranges from 33.9% at Low settings to 34.0% at Ultra settings — a remarkably uniform scaling that suggests the GPU is not becoming the primary bottleneck at this resolution. The RTX 4070 SUPER's 192-bit memory interface and 504.2 GB/s bandwidth provide ample headroom for the increase in pixel count from 2.07 million to 3.69 million.

At 3840x2160, the system still delivers highly playable frame rates. Low settings average 213.9 FPS, Medium settings 190.8 FPS, High settings 167.4 FPS, and Ultra settings 135.9 FPS. The transition from 1440p to 4K involves a pixel count increase of 2.25x, yet the FPS reduction at each settings level is proportionally smaller — for instance, Ultra settings drop from 241.7 FPS to 135.9 FPS, a 43.8% reduction against a 125% increase in pixel count. This non-linear scaling confirms that Roblox's rendering workload does not scale purely with resolution, and that the CPU continues to exert significant influence even at 4K.
