Roblox

Roblox benchmark data for the Intel Core i5-12600KF and NVIDIA GeForce RTX 5090 combination comes from measured FPS rows at 1920x1080, 2560x1440, and 3840x2160, each paired with Low, Medium, High, and Ultra presets. The game is classified as a Sandbox title. The CPU is an Alder Lake-S desktop part with 10 cores, 16 threads, a 3.70 GHz base clock, and a 4.90 GHz boost clock. The GPU is a Blackwell 2.0 design with a 5 nm TSMC process and 32 GB of GDDR7 memory. Every FPS value in this analysis is measured rather than estimated.

Resolution Scaling

The measured matrix shows a consistent pattern: every 1920x1080 row is faster than its 2560x1440 counterpart, and every 2560x1440 row is faster than its 3840x2160 counterpart. At Low settings, the average FPS moves from 734.9 at 1080p to 493 at 1440p to 280.2 at 4K. At Ultra settings, it moves from 481.6 to 322.2 to 180.1. The decline is present across all four presets, and it is large enough to identify resolution as a dominant factor in this game.

At 4K, Low is 280.2, Medium is 252.4, High is 226.9, and Ultra is 180.1. At 1440p, the same settings are 493, 444.9, 396.9, and 322.2. At 1080p, they are 734.9, 672.6, 591.2, and 481.6. The 4K Low result is lower than the 1440p Ultra result, which illustrates how much pixel count affects Roblox. Likewise, the 4K Ultra result at 180.1 is well below every 1080p row, including 1080p Ultra at 481.6.

These numbers point to the GPU as the dominant limiter at higher resolutions. When resolution drops, the GPU has more headroom, and the frame rate rises sharply. At 1080p, the Low setting reaches 734.9 FPS, a number high enough that CPU per-core performance becomes the more plausible limiting factor. The data cannot show a hard ceiling, but the ordering of results is consistent with a system that becomes less GPU-bound as resolution falls.

GPU Role

The RTX 5090 is a large GPU: 92,200 million transistors on a 750 mm² die, with 21,760 shading units, 680 TMUs, 176 ROPs, 170 RT cores, and 680 tensor cores. Its base clock is 2017 MHz and its boost clock is 2407 MHz. The memory configuration is 32 GB GDDR7 on a 512-bit bus, with a 1750 MHz memory clock (28 Gbps effective) and 1.79 TB/s of bandwidth. FP32 throughput is 104.8 TFLOPS.

In database terms, the GPU has an average benchmark score of 84306 and sits at the 94th percentile. Its nearest rivals are the RTX 5090 D (84241, deltaPct 0.1), RTX 5050 Mobile (84171, deltaPct 0.2), AMD Radeon PRO W6600 (83209, deltaPct 1.3), and NVIDIA CMP 40HX (85637, deltaPct -1.6). These scores place the card in a tight cluster, but the measured FPS here is specific to the RTX 5090 and the i5-12600KF.

The 32 GB VRAM is a large allocation for a Sandbox game, and the measured 4K Ultra row is 180.1 FPS. That would be a difficult result to sustain if the GPU were hitting a memory capacity or bandwidth wall. The 4K curve moves smoothly from 280.2 to 252.4 to 226.9 to 180.1, which looks like a settings scaling curve rather than a memory-related collapse. The GPU's PassMark G3D score of 39650 and GPU compute score of 26756 reinforce that the card has substantial raw performance to draw on.

CPU Role

The i5-12600KF has 10 cores and 16 threads with a 3.70 GHz base clock and a 4.90 GHz boost clock. The cache hierarchy includes 80 KB L1 per core, 1.25 MB L2 per core, and 20 MB shared L3. It supports dual-channel DDR4 and DDR5 memory and connects via PCIe Gen 4 with 20 CPU lanes.

In synthetic tests, the CPU scores 23444 in Cinebench R23 multicore, 3309 in Cinebench R23 single-core, and 1016 in 3DMark single-thread. Its average benchmark score is 27827, and it sits at the 84th percentile. The nearest rivals are Core i9-10900K (27829, deltaPct 0), Core i5-12600K (27851, deltaPct -0.1), Core Ultra 5 125H (27872, deltaPct -0.2), and Core i7-13700H (27716, deltaPct 0.4). The cluster is tight: the largest deltaPct among these rivals is 0.4.

The 1080p FPS rows are where single-thread capability matters most. At 1080p Low the combo reaches 734.9 FPS, at Medium 672.6, at High 591.2, and at Ultra 481.6. These are high enough that the GPU is unlikely to be the only constraint. The CPU's 4.90 GHz boost clock and its single-core benchmark scores are the more relevant data points at low resolution. The 10-core and 16-thread configuration still provides strong general throughput, but the measured frame rates suggest that per-core speed, not core count, is what separates this combo at 1080p.

Measured FPS Breakdown

The measured rows contain avgFps values only; min and max FPS are null in the source data. The table below groups the results by resolution and setting.

| Resolution | Low | Medium | High | Ultra |

|---|---|---|---|---|

| 1920x1080 | 734.9 | 672.6 | 591.2 | 481.6 |

| 2560x1440 | 493 | 444.9 | 396.9 | 322.2 |

| 3840x2160 | 280.2 | 252.4 | 226.9 | 180.1 |

The ordering is consistent across every resolution: Low is fastest, then Medium, then High, then Ultra. The slowest measured row is 4K Ultra at 180.1, while the fastest is 1080p Low at 734.9.

At 1080p, Low and Medium sit clearly above High and Ultra. At 1440p, Low and Medium also lead, with High at 396.9 and Ultra at 322.2. At 4K, the spacing between Low, Medium, and High is smaller, and Ultra drops to 180.1. The data does not include frame-time or stutter metrics, so the table should be read as average throughput rather than consistency.

Settings Recommendations

Low is the fastest preset at all three resolutions. The measured FPS values are 734.9 at 1080p Low, 493 at 1440p Low, and 280.2 at 4K Low. Medium is the next-fastest preset everywhere: 672.6 at 1080p, 444.9 at 1440p, and 252.4 at 4K. High and Ultra trail further at each resolution.

Because Medium always sits between Low and High in the measured row order, it is the most balanced choice if the goal is to gain quality while preserving a large frame-rate cushion over the Ultra row. Ultra produces the lowest numbers in each resolution: 481.6 at 1080p, 322.2 at 1440p, and 180.1 at 4K. Without min or max FPS data, a settings recommendation based on frame-time consistency is not possible.

How This Combo Ranks

Within Roblox, this pairing is ranked 10 out of 1800 tested combos. That places the combo in the highest part of the distribution. The GPU's 94th percentile and the CPU's 84th percentile support the same conclusion: both major components are strong performers in the database. The measured FPS table confirms the ranking. Even 4K Ultra, the slowest measured row, averages 180.1 FPS, and the fastest row, 1080p Low, averages 734.9 FPS.
