Roblox

Roblox is a sandbox title that scales unusually well across a wide range of hardware, and the data for the Intel Core i5-12400F paired with the NVIDIA GeForce RTX 4070 Ti reflects that. The measured frames per second are exceptionally high across all tested configurations, indicating that this combination is far beyond what the game requires for smooth play at any resolution. The analysis below walks through how the system behaves under different loads, focusing on where the bottleneck lies and what the numbers imply for the overall experience.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, but the absolute values remain so high that the scaling pattern tells a clearer story than the raw numbers alone. At 1080p with Low settings, the combo produces 590 FPS. Moving to 1440p Low drops that to 393 FPS, a reduction of roughly 33%. At 4K Low, the average falls to 223 FPS, which is another 43% drop from the 1440p figure. This steep decline with increasing resolution indicates that the GPU is becoming the limiting factor as pixel count rises, though the CPU still has headroom to push higher frame rates at lower resolutions.

Looking at the High preset, the scaling is similar but slightly less dramatic in percentage terms. The 1080p High result is 474 FPS, which falls to 317 FPS at 1440p High (a 33% drop) and then to 179 FPS at 4K High (a 44% drop from 1440p). The pattern is consistent: every doubling of resolution roughly halves the frame rate, which is a classic sign of a GPU-bound scenario at higher resolutions. However, the starting point is so high that even the 4K High result of 179 FPS is well above the refresh rate of most displays.

The Ultra preset shows the same trend but with lower absolute numbers. At 1080p Ultra, the average is 385 FPS; at 1440p Ultra, it is 257 FPS; and at 4K Ultra, it drops to 145 FPS. The percentage drop from 1080p to 1440p is about 33%, and from 1440p to 4K it is about 44%, mirroring the other presets. This consistency suggests that the game's rendering pipeline scales predictably with resolution, and the RTX 4070 Ti is the component that determines the ceiling once the resolution increases beyond 1080p.

At 1080p, the data indicates a CPU-limited scenario. The jump from 474 FPS at High to 590 FPS at Low is a 24% increase, which shows that reducing graphical load can still yield higher frame rates. But the gap between Low and Medium at 1080p is smaller: 590 FPS to 536 FPS, a 9% difference. This narrowing suggests that the CPU is starting to cap the frame rate even at 1080p Low, as the GPU is capable of far more than 590 FPS in this lightweight title. The 4K data, by contrast, shows a wider spread between settings, confirming that the GPU is the primary constraint at that resolution.

GPU Role

The RTX 4070 Ti brings 12 GB of GDDR6X memory on a 192-bit bus, with a bandwidth of 504.2 GB/s. For a game like Roblox, which is not known for heavy texture streaming or massive memory footprints, 12 GB is far more than adequate. The data shows no signs of memory capacity being a factor: even at 4K Ultra, the average FPS is 145, which is still playable, and the lack of a min FPS reading for most configurations suggests that frame pacing is not a concern.

Clock speeds are high, with a base of 2310 MHz and a boost of 2610 MHz. The GPU is built on the Ada Lovelace architecture using a 5 nm process from TSMC, which contributes to its efficiency. The measured results show that the card can sustain very high frame rates even at 4K, with the Low preset yielding 223 FPS and Medium yielding 203 FPS. The fact that the GPU is end-of-life in production status does not diminish its current performance in this title, as the data is measured and reflects real-world behavior.

The GPU's benchmark scores place it in the 84th percentile of all GPUs, with an average benchmark score of 44795. Its nearest rivals include the NVIDIA GeForce RTX 5090 Mobile, which scores 45152 and is 0.8% faster, and the AMD Radeon Pro 5500 XT at 45384, which is 1.3% faster. These deltas are negligible in a game like Roblox, where the frame rates are already hundreds of FPS. The GPU's role in this combo is to provide enough raw throughput to avoid being a bottleneck at 1440p and below, and it does so with significant headroom.

How This Combo Ranks

Among the 3711 tested combos in Roblox, this pairing of the Intel Core i5-12400F and the NVIDIA GeForce RTX 4070 Ti ranks 519th. That places it in the top 14% of all combinations tested, which is a strong showing given the game's low system requirements. The rank reflects the fact that the GPU is powerful enough to push high frame rates, but the CPU also contributes by not holding the system back at lower resolutions.

The CPU itself sits in the 73rd percentile of all CPUs, with an average benchmark score of 19039. Its nearest rivals include the AMD Ryzen 5 7535HS, which scores 19047 and is essentially tied, and the Intel Core 3 201E at 19056, which is 0.1% faster. The i5-12400F holds its own against these competitors, and in Roblox, the combination's rank is more influenced by the GPU than the CPU, given that the game is not heavily threaded.

The rank of 519 out of 3711 means that there are many other combos that achieve higher frame rates, likely those with even more powerful GPUs like the RTX 4090 or newer RTX 50-series cards. However, for the vast majority of users, a rank in the top 14% is more than sufficient, as the frame rates are already at levels that exceed typical display refresh rates.

Measured FPS Breakdown

At 1080p, the data shows a clear hierarchy across settings. Low yields an average of 590 FPS, Medium 536 FPS (with a min of 456 and max of 617), High 474 FPS, and Ultra 385 FPS. The spread from Low to Ultra is 205 FPS, which is a 35% reduction in performance when maxing out the settings. This indicates that the GPU is still capable of handling the load at 1080p, but the CPU may be starting to limit the Low preset's ability to go even higher.

At 1440p, the averages are 393 FPS for Low, 358 FPS for Medium (min 304, max 412), 317 FPS for High, and 257 FPS for Ultra. The gap between Low and Ultra narrows to 136 FPS, a 35% reduction as well, but the absolute numbers are lower. The Medium preset shows a min FPS of 304, which is still far above any playable threshold, indicating that frame dips are not a concern at this resolution.

At 4K, the results are 223 FPS for Low, 203 FPS for Medium (min 172, max 233), 179 FPS for High, and 145 FPS for Ultra. The min FPS at 4K Medium is 172, which is the lowest recorded value across all configurations, but it is still well above 60 FPS. The spread from Low to Ultra is 78 FPS, a 35% reduction, consistent with the other resolutions. This consistency suggests that the game scales settings uniformly, and the RTX 4070 Ti maintains a high level of performance even at the most demanding settings.

CPU Role

The Intel Core i5-12400F has 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. It belongs to the Alder Lake architecture, built on a 10 nm process, and supports both DDR4 and DDR5 memory. For Roblox, which is not a heavily threaded game, the 6 cores and 12 threads are more than sufficient. The single-thread performance is what matters most, and the benchmark scores reflect that: a 3dmark single-thread score of 909 and a passmark single-thread score of 3481.

The CPU's multi-threaded scores are also strong, with a cinebench r23 multicore score of 12380 and a geekbench multicore score of 9472. However, in Roblox, these are less relevant. The data shows that at 1080p Low, the frame rate is 590 FPS, which is likely near the CPU's limit for this game's engine. The fact that the GPU is not the bottleneck at this resolution is evident from the 4K Low result of 223 FPS, which is less than half of the 1080p Low figure, confirming that the GPU is fully utilized at higher resolutions.

The CPU's nearest rivals, such as the AMD Ryzen 5 7535HS, have similar average benchmark scores, with a delta of 0%. In Roblox, the difference between these CPUs would be minimal, as the game's frame rates are more dependent on single-core speed. The i5-12400F's boost clock of 4.40 GHz is competitive, and the data suggests that it does not cause a noticeable bottleneck until the frame rate reaches around 590 FPS at 1080p Low.

Settings Recommendations

Based on the measured rows, the best experience depends on the target resolution. At 1080p, the High preset at 474 FPS offers a good balance, as it provides a significant visual improvement over Low while still delivering nearly 500 FPS. The Ultra preset drops to 385 FPS, which is still excellent but offers diminishing returns for the 19% performance hit. For users with a high refresh rate monitor (240 Hz or more), the Low preset at 590 FPS would be the best choice to maximize smoothness.

At 1440p, the High preset at 317 FPS is the recommended sweet spot. It provides a solid visual quality while maintaining frame rates that exceed most 240 Hz displays. The Ultra preset at 257 FPS is also viable, but the 19% drop from High is not justified by the visual gains in a game like Roblox. The Medium preset at 358 FPS is another option for those who prioritize frame rate over visuals, as it offers a 13% improvement over High.

At 4K, the High preset at 179 FPS is the best choice for a balance of quality and performance. The Ultra preset at 145 FPS is still playable and would be suitable for users with a 144 Hz display, but the drop from High is 19%. The Medium preset at 203 FPS is the top choice for frame rate enthusiasts, as it delivers over 200 FPS even at 4K. The Low preset at 223 FPS is only marginally better than Medium and sacrifices too much visual fidelity for a 10% gain.
