# CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-12400F is a 6-core, 12-thread processor from the Alder Lake generation, built on Intel's 10 nm process. Its base clock is 2.50 GHz with a boost clock of 4.40 GHz. The chip has an 18 MB shared L3 cache, plus 1.25 MB L2 and 80 KB L1 per core. It supports DDR4 and DDR5 memory in a dual-channel configuration, and connects via PCIe Gen 5 with 20 lanes from the CPU. The processor's launch MSRP is $174.

Benchmark results show this CPU is a strong mid-range performer. In Cinebench R23, it scores 16518 multi-core and 2332 single-core. Geekbench results show 9138 multi-core and 2221 single-core. The 3DMark suite shows a clear scaling trend: 1699 for 2 threads, 3067 for 4 threads, 4779 for 8 threads, 5895 for 16 threads, and 5912 for max threads. This indicates that performance gains taper off beyond 8 threads, meaning the 6-core/12-thread design is well-balanced for this workload.

Against its nearest rivals, the i5-12400F sits nearly dead-center. It edges out the Intel Core i7-8700K by 0.1% and the Intel Core i5-1335U by 0.3%, while trailing the AMD Ryzen 5 7533HS by 0.7% and leading the AMD EPYC 7773X by 1.3%. These are tight margins—all four rivals are within a 2% band of each other. The CPU's 77th percentile ranking among all CPUs places it comfortably in the upper tier for gaming.

In Roblox specifically, the CPU's role is modest but important. The measured FPS data shows that even at 1080p Low settings—where the GPU has the least work—the system hits 433.6 FPS. This is not a CPU-bound scenario; the i5-12400F has enough headroom to feed the RTX 3070 Ti without becoming a bottleneck. The 12 threads handle Roblox's typically light physics and scripting loads easily. Given that the CPU's single-thread score of 2332 in Cinebench R23 is strong, and Roblox is not heavily multithreaded, this processor will not limit frame rates in any of the measured configurations.

# GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 3070 Ti is built on the Ampere architecture using Samsung's 8 nm process. The GA104 chip packs 17,400 million transistors across a 392 mm² die. It has 6144 shading units, 192 texture mapping units, and 96 raster output pipelines. The GPU includes 48 RT cores and 192 tensor cores. Its base clock is 1575 MHz with a boost clock of 1770 MHz. Memory speed is 1188 MHz, translating to 19 Gbps effective.

The memory subsystem consists of 8 GB of GDDR6X on a 256-bit bus, providing 608.3 GB/s of bandwidth. This is a critical specification for Roblox, which is a sandbox game where user-generated worlds can feature high-resolution textures. The pixel rate is 169.9 GPixel/s, and the texture rate is 339.8 GTexel/s. The GPU delivers 21.75 TFLOPS of FP32 performance and 21.75 TFLOPS of FP16.

In benchmark tests, the RTX 3070 Ti scores 23356 in Passmark G3D and 137518 in Geekbench OpenCL. Its Passmark DirectX 11 score of 192 and DirectX 12 score of 91 show strong API-specific performance. The 74th percentile ranking among all GPUs places it in the upper-mid range. Compared to its nearest rivals, it leads the AMD Radeon RX 590 GME by 0.3% and trails the AMD Radeon RX 6700 by 0.8%, the NVIDIA Quadro M5000 by 0.9%, and the NVIDIA GRID M60-1Q by 1.2%. These deltas are negligible in practice.

In Roblox, the GPU is the primary driver of frame rates. The measured data shows a clear pattern: at 4K Ultra, the average FPS drops to 105, while at 1080p Low it reaches 433.6. The 8 GB VRAM is sufficient for Roblox's texture loads even at 4K Ultra, as evidenced by the playable 105 FPS at that setting. The bandwidth of 608.3 GB/s handles the game's geometry and draw calls smoothly. The RTX 3070 Ti's 48 RT cores are not heavily utilized in Roblox, but the raw rasterization performance is what matters here, and the data confirms it delivers.

# Settings Recommendations — which preset gives the best experience per the measured rows

The measured FPS data provides clear guidance on settings selection across the three resolutions tested. At 1080p, all four presets deliver well above 240 FPS, making this resolution ideal for high-refresh-rate monitors. The Ultra preset at 1080p yields 282.4 FPS, which is still excellent. The jump from Low to Ultra at 1080p costs 151.2 FPS (from 433.6 to 282.4), a 34.9% reduction, but the visual quality improvement is substantial.

At 1440p, the situation remains comfortable. High settings produce 235 FPS, and Ultra produces 190.5 FPS. Both are well above the 144 Hz refresh rate common on 1440p monitors. The difference between Low (291.2 FPS) and Ultra (190.5 FPS) is 100.7 FPS, representing a 34.6% drop, which is proportionally similar to 1080p. The medium preset at 1440p hits 262.2 FPS, offering a balanced trade-off.

At 4K, the data changes character. Ultra settings drop to 105 FPS, which is still playable but below the 144 Hz threshold. High settings at 4K produce 133.4 FPS, and Medium produces 149.8 FPS. Low settings at 4K deliver 162.6 FPS. The scaling from Ultra to Low at 4K is 57.6 FPS (from 105 to 162.6), a 54.9% improvement.

For the best overall experience, 1440p High settings is the sweet spot. It delivers 235 FPS, which exceeds the refresh rate of all but the most extreme gaming monitors, while maintaining solid visual fidelity. If the user prefers maximum visual quality, 1440p Ultra at 190.5 FPS remains a strong choice. For 4K users, High settings at 133.4 FPS is the recommended preset—it avoids the Ultra preset's drop below 110 FPS while keeping the visual experience close to the top tier.

# How This Combo Ranks — use comboRankInGame vs other tested combos

This combination of the Intel Core i5-12400F and the NVIDIA GeForce RTX 3070 Ti ranks 730th out of 1800 tested combos in Roblox. This places it in the 59.4th percentile of all tested systems—meaning it outperforms roughly 59% of the combos in the database while being outperformed by about 41%. This is a solidly above-average result, though not a top-tier one.

The ranking context is important. Roblox is a lightweight game that does not heavily stress high-end hardware. Many combos with weaker GPUs but strong CPUs can achieve high frame rates because the game's engine is not graphically demanding. The 730th rank suggests that this combo is neither overkill nor underpowered for Roblox—it sits in a practical zone where the hardware is capable but not at the extreme top.

The rank of 730 also reflects the balance of this pairing. The i5-12400F is not the fastest CPU in the database, and the RTX 3070 Ti is not the fastest GPU. However, they work well together in Roblox. The CPU's 12 threads and high single-thread performance ensure the GPU is fed properly, while the GPU's 8 GB VRAM and 608.3 GB/s bandwidth handle the game's visual load. The result is a system that delivers strong frame rates across all settings and resolutions, as the measured FPS data confirms.

# Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

1920x1080 (1080p)

The system delivers exceptional performance at this resolution. Low settings produce 433.6 FPS, Medium produces 395.9 FPS, High produces 347.5 FPS, and Ultra produces 282.4 FPS. The scaling is smooth, with each preset step costing roughly 40-50 FPS. Even the most demanding preset, Ultra, stays well above 240 FPS, making this resolution suitable for the fastest gaming monitors available.

2560x1440 (1440p)

At this resolution, the frame rates remain high but the gap between presets widens. Low settings reach 291.2 FPS, Medium reaches 262.2 FPS, High reaches 235 FPS, and Ultra reaches 190.5 FPS. The step from High to Ultra costs 44.5 FPS, which is the largest single-step drop in this resolution. All presets exceed 144 Hz, making 1440p the sweet spot for high-refresh-rate gaming.

3840x2160 (4K)

This is where the GPU's limits become visible. Low settings produce 162.6 FPS, Medium produces 149.8 FPS, High produces 133.4 FPS, and Ultra drops to 105 FPS. The scaling is nearly linear from Medium to Ultra, with each step costing roughly 15-22 FPS. Low and Medium presets exceed 144 Hz, while High and Ultra fall below that threshold. The 4K Ultra result of 105 FPS is the only measured configuration that dips below 120 FPS, indicating that the RTX 3070 Ti is well-matched to this game even at the highest resolution tested.
