Roblox

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4070 delivers exceptionally high frame rates in Roblox across all tested resolutions and settings. The measured data shows average FPS figures ranging from 122.8 at 4K Ultra to 502.2 at 1080p Low, with every configuration far exceeding the 60 FPS playability threshold. This combination ranks 948th out of 3711 tested combos in this game, placing it in the upper quartile of performance. The benchmark results indicate that this system is overwhelmingly GPU-bound at lower resolutions, while the CPU begins to assert more influence at 4K, though both components remain well within their performance envelopes.

Measured FPS Breakdown

The measured FPS data covers three resolutions—3840x2160, 2560x1440, and 1920x1080—each tested at four settings presets: Low, Medium, High, and Ultra. The dataset provides average FPS values, while minimum and maximum FPS fields are null for all entries, meaning the analysis relies solely on averages.

At 3840x2160, the average FPS ranges from 122.8 at Ultra to 190.3 at Low. The progression is orderly: Low delivers 190.3, Medium drops to 173.1, High falls to 150.5, and Ultra bottoms out at 122.8. The spread between Low and Ultra is 67.5 FPS, representing a 35.5% reduction in average frame rate when moving from the least to most demanding preset. Notably, even the worst-case Ultra setting at 4K produces more than double the 60 FPS playability threshold.

Moving to 2560x1440, the average FPS values are substantially higher. Low settings produce 334.4 FPS, Medium reaches 303.2, High achieves 269.2, and Ultra maintains 221.2. The delta between Low and Ultra is 113.2 FPS, which is a 33.9% decrease. This resolution shows that the RTX 4070 has significant headroom, as even the most demanding preset at 1440p delivers over 220 FPS on average.

At 1920x1080, the performance becomes extraordinary. Low settings produce 502.2 FPS, Medium reaches 457.2, High achieves 404.6, and Ultra still maintains 326.2 FPS. The difference between Low and Ultra is 176.0 FPS, a 35.0% reduction. Every 1080p configuration exceeds 300 FPS on average, suggesting that the system is capable of driving high-refresh-rate monitors without any difficulty.

Across all resolutions, the scaling pattern is consistent. Moving from Low to Medium costs roughly 9-10% of average FPS, from Medium to High another 10-12%, and from High to Ultra a further 14-18%. The percentage drop is slightly steeper at 4K, where the GPU workload increases more rapidly with each preset tier. The data shows no anomalies or outliers—the frame rates scale predictably with both resolution and settings.

CPU and GPU Roles

The division of labor between the Intel Core i5-12400F and the NVIDIA GeForce RTX 4070 in Roblox can be inferred from how frame rates scale with resolution and settings changes. Roblox is a sandbox game that relies heavily on CPU single-thread performance for game logic and physics, while the GPU handles rendering tasks. The data shows distinct patterns at each resolution.

At 1920x1080, the GPU is the dominant performance factor. The average FPS at Low settings is 502.2, and increasing to Ultra reduces this to 326.2. The 176.0 FPS drop indicates that the GPU is being tasked with progressively heavier rendering workloads. However, even at Ultra, the frame rate remains high enough that the CPU's ability to feed the GPU is not a limiting factor. The i5-12400F's single-thread score of 909 in 3dmark and 1680 in Cinebench R23 single-core are sufficient to sustain these frame rates.

At 2560x1440, the relationship shifts slightly. The average FPS at Low is 334.4, dropping to 221.2 at Ultra. The absolute numbers are lower than at 1080p, which is expected because the GPU must render more pixels. The percentage reduction from Low to Ultra is 33.9%, nearly identical to the 35.0% reduction at 1080p. This consistency suggests that the GPU workload scales proportionally with pixel count, and the CPU is still able to keep up with the demands of the game engine.

At 3840x2160, the CPU's role becomes more apparent. The average FPS at Low is 190.3, and at Ultra it drops to 122.8. The reduction from Low to Ultra is 35.5%, which is slightly steeper than at lower resolutions. This indicates that at 4K, the GPU is working hard enough that its frame time variance begins to interact with the CPU's frame generation rate. The i5-12400F's multi-thread score of 12380 in Cinebench R23 and 19433 in Passmark multi-thread suggest it has ample headroom, but the game's single-threaded nature means the CPU's single-core performance of 1680 in Cinebench R23 single-core is the relevant metric. At 4K Ultra, the system is still delivering 122.8 FPS, so neither component is critically strained.

The scaling between resolutions reveals that the GPU is the primary bottleneck as resolution increases. Moving from 1080p to 1440p at Ultra settings reduces average FPS from 326.2 to 221.2, a 32.2% decrease. Moving from 1440p to 4K at Ultra reduces FPS from 221.2 to 122.8, a 44.5% decrease. The larger percentage drop at higher resolutions is characteristic of a GPU-bound scenario where the RTX 4070's rendering throughput becomes the limiting factor. The CPU, with its 6 cores and 12 threads, provides consistent frame generation across all tested configurations.

How This Combo Ranks

The combo rank for this Intel Core i5-12400F and NVIDIA GeForce RTX 4070 combination in Roblox is 948 out of 3711 tested combos. This places the system in the 74.5th percentile, meaning it outperforms approximately 74.5% of all tested hardware combinations for this game. The rank reflects the measured FPS data, which shows that this system delivers well above the 60 FPS threshold at every resolution and settings combination.

The rank of 948 is notable because it places this combo in the upper echelon of performance, but not at the very top. The top 25% of combos likely include higher-end GPUs such as the RTX 4080 or 4090, or CPUs with higher single-thread performance. However, the data shows that the i5-12400F and RTX 4070 combination is more than sufficient for Roblox, as the game's rendering demands are moderate compared to AAA titles.

The percentile ranking of 81 for the GPU versus all GPUs indicates that the RTX 4070 is a high-performing component in general. The CPU's percentile of 73 versus all CPUs is slightly lower but still above average. When combined in Roblox, the system performs better than the individual percentiles might suggest, because the game is not heavily multi-threaded and the GPU has ample headroom at most resolutions. The rank of 948 out of 3711 confirms that this is a capable gaming system for Roblox, with no configuration falling below the playability threshold.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-12400F, based on average benchmark scores, include the AMD Ryzen 5 7535HS with an average score of 19047 (0% delta), the Intel Core 3 201E with 19056 (-0.1% delta), the Intel Core i5-1335U with 18982 (0.3% delta), and the AMD EPYC 7773X with 18979 (0.3% delta). These CPUs have nearly identical average benchmark scores, meaning they would behave similarly in Roblox from a CPU perspective. The Ryzen 5 7535HS and Core i5-1335U are both mobile-oriented parts, while the Core 3 201E is a low-power desktop chip. The EPYC 7773X is a server processor, but its similar score indicates comparable computational throughput for this workload.

For the NVIDIA GeForce RTX 4070, the nearest rivals include the NVIDIA Tesla P4 with an average score of 37628 (0.1% delta), the AMD Radeon RX Vega 56 with 37507 (0.4% delta), the NVIDIA GeForce RTX 4080 Mobile with 38135 (-1.3% delta), and the AMD Radeon PRO W6400 with 37157 (1.3% delta). The Tesla P4 is a data-center card, while the RX Vega 56 is a previous-generation desktop GPU. The RTX 4080 Mobile is a laptop variant that scores slightly higher, and the PRO W6400 is a workstation card. All of these GPUs have average scores within 1.3% of the RTX 4070, so they would produce similar frame rates in Roblox at the tested settings.

A system pairing any of these rival CPUs with the RTX 4070 would likely produce FPS figures within a few percentage points of the measured values. Similarly, pairing the i5-12400F with any of the rival GPUs would yield comparable performance, given the small score deltas. The data suggests that hardware within this performance band is interchangeable for Roblox, as the game's modest requirements mean that even slightly slower components can still exceed 60 FPS at all resolutions.

The Verdict

The verdict is unambiguous: this PC can run Roblox at playable frame rates across every resolution and settings combination tested. The verdictByResolution data lists all four settings presets—Low, Medium, High, and Ultra—as playable at 3840x2160, 2560x1440, and 1920x1080. The playable threshold of 60 FPS is cleared by a wide margin in every case.

At 3840x2160, the best settings preset is Ultra, with an average FPS of 122.8. This is more than double the 60 FPS threshold, providing a comfortable margin for frame-time spikes.
