Roblox

Roblox is not a typical GPU stress test, and the data for the Intel Core i7-12700KF paired with the NVIDIA GeForce RTX 4070 Ti proves it. The measured frame rates are extraordinarily high across the board, but the way they scale with resolution reveals a system that is heavily bound by the CPU at lower settings and only begins to lean on the graphics card when the pixel count climbs. This combination sits at rank 254 out of 1800 tested combos, placing it in the top tier of configurations for this specific title, but the performance profile is more nuanced than a simple ranking suggests.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate scaling from 1080p to 4K is the clearest indicator of where the bottleneck lies. At 1080p with Low settings, the system produces 587.5 FPS. Moving to 1440p drops that to 396.6 FPS, a reduction of 190.9 FPS, and at 4K it falls further to 221.1 FPS. This is a dramatic decline that does not follow a linear path based on pixel count alone. If the GPU were the sole limiting factor, the drop from 1440p to 4K would be proportionally steeper than the drop from 1080p to 1440p. Instead, the data shows a more even decline, which points to a CPU limit being reached first.

The evidence becomes clearer when looking at the High settings. At 1080p High, the system hits 471.8 FPS, which is still a massive number. At 1440p High, it drops to 314.3 FPS, and at 4K High, it lands at 181.4 FPS. The delta between 1080p and 1440p is 157.5 FPS, while the delta between 1440p and 4K is 132.9 FPS. These are similar in magnitude, suggesting that the CPU is still managing to feed the GPU enough data at 1440p to keep the frame rate high, but the GPU is starting to become more relevant as the resolution increases.

At 4K, the scale tips. The gap between Low and Ultra settings becomes much more pronounced, which is a classic sign of the GPU finally becoming the primary constraint. The difference between 221.1 FPS at Low and 147.5 FPS at Ultra is a 73.6 FPS swing, a much larger percentage difference than at 1080p. This indicates that at 4K, the RTX 4070 Ti's rendering workload is significant enough to matter, whereas at 1080p, the CPU is so fast that the GPU is often waiting for instructions.

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

The NVIDIA GeForce RTX 4070 Ti is a formidable piece of silicon, but its role in Roblox is more about headroom than necessity. The GPU's 12 GB of GDDR6X memory is far beyond what Roblox requires, as the game's art style and asset complexity do not typically stress memory capacity. The memory bandwidth of 504.2 GB/s, delivered over a 192-bit bus, is also more than sufficient for the data throughput needed at the resolutions tested. The data suggests that VRAM is not a limiting factor in any of the measured scenarios, as the frame rates remain high even at 4K Ultra.

The GPU's clock speeds are high, with a base of 2310 MHz and a boost of 2610 MHz. This boost clock is crucial for maintaining high frame rates in a game that can have sudden spikes in geometry or effects. The Ada Lovelace architecture, built on a 5 nm process, provides the efficiency to sustain these clocks without thermal throttling, which is important for maintaining consistent performance over long sessions. The shading units and ray tracing cores are present in large numbers, but Roblox's rendering pipeline, as measured here, does not appear to use them to their full extent.

The benchmark results show the GPU is capable of massive compute throughput, with a Passmark G3D score of 31624 and an average benchmark score of 44900. However, in this game, the GPU's role is secondary. At 1080p, the frame rates are so high that the GPU is likely idling or running at lower utilization, waiting for the CPU to send draw calls. The data indicates that the RTX 4070 Ti is a safety net, ensuring that even the most complex Roblox worlds render at high frame rates, but it is not the component that defines the experience at lower resolutions.

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

The Intel Core i7-12700KF is the true engine of this configuration for Roblox. With 12 cores and 20 threads, it has ample parallel processing capability, but the game's performance is likely more dependent on the single-thread and lightly-threaded performance. The benchmark data shows a strong single-core score of 3984 in Passmark, which is critical for a game that often has a primary game logic thread. The boost clock of 5.00 GHz provides the raw speed needed to process the game's physics and scripting quickly.

The CPU's multi-threaded performance is also excellent, with a Cinebench R23 multi-core score of 28979. This is relevant because Roblox can use multiple threads for different tasks, such as rendering chunks or handling network updates. The 3DMark scores show a clear scaling from 2 threads (2065) to 16 threads (9282), indicating that the CPU can effectively distribute work across its cores. This is likely why the frame rates at 1080p are so high; the CPU can handle the game's logic and still have headroom to feed the GPU.

The architecture, Alder Lake-S, is built on a 10 nm process and supports a large 25 MB shared L3 cache. This cache is beneficial for keeping frequently accessed game data close to the cores, reducing latency. The data shows that the CPU is performing at the 89th percentile compared to all CPUs, placing it in the top tier. The nearest rivals, such as the Intel Core i5-14400 and Intel Core i7-13800H, have nearly identical average scores, but the 12700KF's single-thread performance is what likely gives it an edge in a game like Roblox.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the i7-12700KF and RTX 4070 Ti achieves a rank of 254 out of 1800 tested combos. This places it in the top 14% of all configurations tested. This is a strong result, but it is not the absolute top tier. The ranking suggests that there are 253 other combos that produce higher frame rates, which likely include newer, more powerful CPUs or GPUs. However, the data implies that this combo is in the upper echelon, capable of delivering a very high frame rate experience in Roblox.

The GPU's nearest rivals, based on average benchmark score, are the NVIDIA GeForce RTX 5090 Mobile, Intel Arc A730M, AMD Radeon Pro 580, and AMD Radeon Pro 5500 XT. The delta percentages are small, ranging from -1.6% to +1.6%, indicating that in synthetic benchmarks, these are close performers. However, in Roblox, the actual frame rate is likely more dependent on the CPU. The CPU's nearest rivals are the i5-14400, i7-13800H, i9-12900HX, and i5-13600T, all with delta percentages of less than 0.3%. This shows that the CPU is in a very tight competitive cluster, and the ranking could be influenced by small performance differences. The fact that this combo ranks 254 suggests that the combination of this specific CPU and GPU is well-balanced, but not the absolute best for this title.

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

The measured data provides clear guidance on which settings preset to use. At 1080p, even the Ultra preset delivers 383.5 FPS, which is far beyond the refresh rate of any standard monitor. The Low preset at 1080p achieves 587.5 FPS, but this is unnecessary headroom. The High preset at 1080p (471.8 FPS) offers a better balance, as it will provide a more visually rich experience while still maintaining frame rates that are far above any display's capability. The data suggests that at 1080p, the user can afford to use Ultra settings without any practical downside, as the frame rate remains exceptionally high.

At 1440p, the High preset delivers 314.3 FPS, which is still a fantastic experience. The Ultra preset at 1440p drops to 259.7 FPS, which is still very high and likely smooth on a high-refresh monitor. However, the Medium preset at 357.9 FPS offers a significant frame rate boost over Ultra with only a modest visual compromise. For users with a 144Hz or 240Hz monitor, the High preset at 1440p is the sweet spot, providing a visual upgrade over Medium while keeping frame rates well above the display's refresh rate. For 4K, the High preset at 181.4 FPS is the best choice. The Ultra preset at 147.5 FPS is playable, but the drop to 181.4 FPS at High is worth it for the additional fluidity.

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

The complete dataset shows a clear performance hierarchy. At 4K (3840x2160), the frame rates are as follows: Low settings produce 221.1 FPS, Medium settings produce 201.5 FPS, High settings produce 181.4 FPS, and Ultra settings produce 147.5 FPS. The progression is smooth, with a 19.6 FPS drop from Low to Medium, a 20.1 FPS drop from Medium to High, and a 33.9 FPS drop from High to Ultra. The Ultra preset is the most demanding, taking a significant hit compared to the other settings.

At 1440p (2560x1440), the frame rates jump considerably. Low settings produce 396.6 FPS, Medium settings produce 357.9 FPS, High settings produce 314.3 FPS, and Ultra settings produce 259.7 FPS. The gaps between settings are larger than at 4K, with a 38.7 FPS drop from Low to Medium, a 43.6 FPS drop from Medium to High, and a 54.6 FPS drop from High to Ultra. This suggests that as the resolution decreases, the CPU has more headroom to push higher frame rates, but the GPU's workload still scales with settings.

At 1080p (1920x1080), the frame rates are at their peak. Low settings produce 587.5 FPS, Medium settings produce 535.4 FPS, High settings produce 471.8 FPS, and Ultra settings produce 383.5 FPS. The delta between Low and Medium is 52.1 FPS, between Medium and High is 63.6 FPS, and between High and Ultra is 88.3 FPS. The Ultra setting has the most significant impact, showing that the highest quality presets do require more GPU resources, but the absolute numbers are still staggeringly high.
