Roblox

Roblox is not a typical graphics stress test, yet the data for this combination of an Intel Core i7-12700KF and an NVIDIA GeForce RTX 5090 places it at rank 96 out of 3711 tested combos. That puts it in the top 2.6% of all systems tested for this title, which is a strong result but not the absolute peak of the leaderboard. The ranking suggests that while this pairing is exceptionally fast, the game's engine and the specific workload favor other configurations slightly more. The i7-12700KF itself sits at the 85th percentile among all CPUs, and the RTX 5090 ranks at the 92nd percentile among all GPUs, so the hardware is consistently near the top of the charts, but the combination in Roblox does not amplify those scores into a top-tier rank.

The gap between this combo and the very best systems is more about the nature of Roblox than about a hardware deficiency. The data shows this combo is 0.2% behind the Intel Core i7-12700K in CPU benchmark averages, which is a negligible difference, and it is 0.1% behind the Intel Core i7-13700T. On the GPU side, the RTX 5090 is 0.3% ahead of the NVIDIA Tesla P100 PCIe 16 GB and 1.1% ahead of the AMD Radeon RX 6850M XT in average benchmark scores. These are tiny margins that indicate the hardware is performing exactly as expected, but the game's frame rate ceiling is often dictated by factors other than raw compute power, such as single-threaded engine logic or network latency, which the benchmark data does not directly measure.

How This Combo Ranks

The combo rank of 96 out of 3711 is a clear signal of top-tier performance. To contextualize this, consider that the CPU alone is within a fraction of a percent of its closest rivals: the Intel Core i7-13700T and the Intel Core i5-13600T are only 0.1% and 0.2% away from the i7-12700KF's average score, respectively. The i7-12700K is 0.2% behind the KF variant, meaning there is no meaningful performance difference between these processors in a general workload. The RTX 5090's nearest rivals are also extremely close, with the Tesla P100 PCIe 16 GB trailing by only 0.3% and the Radeon RX 6850M XT trailing by 1.1%. This indicates that the components are performing right at their expected levels, and the rank is determined by how the game interacts with this specific hardware combination.

What drives the rank higher or lower is the game's ability to utilize the hardware. With a 12-core, 20-thread CPU and a 32 GB GPU, the system has massive resources, but Roblox is often a lighter workload. The data shows the combo achieves an average of 728 FPS at 1080p Low settings, which is an enormous number, but it is not the highest in the database. The rank difference likely comes from systems with CPUs that have higher single-thread scores, as the game may be more sensitive to that metric. The i7-12700KF has a single-thread benchmark score of 1043 in 3DMark and 4071 in Cinebench R23, which are strong but not class-leading. The percentile ranking of 85th for the CPU and 92nd for the GPU suggests that while these are premium parts, there are faster options available, and those faster options are what occupy the top 95 spots in the combo ranking.

GPU Role

The NVIDIA GeForce RTX 5090 is an absolute monster of a graphics card, and its role in this combo is to remove any possible GPU bottleneck. It comes with 32 GB of GDDR7 memory on a 512-bit bus, delivering a bandwidth of 1.79 TB/s. This is a massive amount of memory bandwidth, which is overkill for Roblox but ensures that texture streaming and draw calls are never stalled. The card's boost clock is rated at 2407 MHz, with a base clock of 2017 MHz, and it houses 21760 shading units alongside 170 ray tracing cores and 680 tensor cores. For a game like Roblox, which typically does not use heavy ray tracing or AI features, these compute resources are mostly idle, but they contribute to the card's ability to push extreme frame rates at high resolutions.

The GPU's performance in the data is consistent with its specifications. It scores 39650 in Passmark G3D and 334370 in Geekbench OpenCL, which are top-tier scores. However, in Roblox, the GPU is not the limiting factor. The measured FPS at 1080p Low is 728, and at 4K Ultra it drops to 179. That drop is substantial, but it is not a sign of GPU weakness; rather, it is a sign that the game's engine is scaling the workload. The VRAM usage is never a concern, as 32 GB is far more than any Roblox world requires. The data suggests that the GPU is capable of handling the game at any setting without breaking a sweat, and the frame rate differences between settings are more about the CPU's ability to feed the GPU with draw calls. The card's memory clock of 1750 MHz (28 Gbps effective) and its 1.79 TB/s bandwidth ensure that even at 4K, there is no memory-related stutter, which is reflected in the 4K High average of 221 FPS.

Resolution Scaling

The performance scaling from 1080p to 4K is revealing about where the bottleneck lies in this system. At 1080p Low, the combo hits 728 FPS. Moving to 1440p Low, it drops to 486 FPS, a 33% reduction. At 4K Low, it falls to 275 FPS, which is a 62% reduction from 1080p. This scaling pattern is typical of a system that is CPU-limited at lower resolutions and becomes more GPU-bound as resolution increases. The CPU is the primary driver of the 1080p frame rate, and the GPU is barely taxed. As the resolution increases, the GPU's workload grows, and the frame rate drops accordingly, but even at 4K, the frame rates are so high that the GPU is still not fully utilized.

The data for Medium settings shows a similar trend. At 1080p Medium, the average is 662 FPS, at 1440p Medium it is 442 FPS, and at 4K Medium it is 250 FPS. The drop from 1080p to 1440p is 33%, and from 1080p to 4K is 62%, which is nearly identical to the Low settings scaling. This consistency indicates that the game's graphics settings do not change the fundamental balance between CPU and GPU load; the CPU is always the limiting factor at 1080p, and the GPU becomes more involved at 4K. At Ultra settings, the frame rates are lower across the board, but the scaling is similar: 475 FPS at 1080p, 317 FPS at 1440p, and 179 FPS at 4K. The 4K Ultra figure is the lowest in the dataset, but it is still well above 144 Hz, meaning that a high-refresh-rate 4K monitor can be fully driven.

What this scaling tells a builder is that the RTX 5090 is not the component holding back performance at 1080p. The CPU is. The i7-12700KF is a fast processor, but its single-thread score of 4071 in Cinebench R23 is not the highest available. If a user wants to maximize 1080p frame rates, they would need a CPU with a higher single-thread score, but the gains would be marginal given that the system already exceeds 700 FPS. At 4K, the GPU is doing more work, but the frame rates are still high enough that the CPU is not a major concern. The system is well-balanced for high-resolution gaming, but it is overkill for 1080p, where the CPU limits the GPU.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across three resolutions and four quality presets. At 1920x1080, the system delivers an average of 728 FPS on Low settings, 662 FPS on Medium, 585 FPS on High, and 475 FPS on Ultra. The Medium preset has a recorded minimum of 563 FPS and a maximum of 762 FPS, indicating a stable frame delivery with a 199 FPS spread. This is the only preset with min/max data, but the average figures are consistent with the expectation that higher settings increase GPU load and lower the frame rate. The difference between Low and Ultra at 1080p is 253 FPS, which is a 35% reduction, showing that even the most demanding settings do not cripple the system.

Moving to 2560x1440, the averages drop to 486 FPS on Low, 442 FPS on Medium, 391 FPS on High, and 317 FPS on Ultra. The Medium preset again has min/max data, with a minimum of 376 FPS and a maximum of 508 FPS. The spread is 132 FPS, which is tighter than at 1080p, suggesting that the GPU is becoming more involved and smoothing out the frame delivery. The drop from Low to Ultra at 1440p is 169 FPS, a 35% reduction, which matches the percentage drop seen at 1080p. This similarity indicates that the relative cost of each setting level is consistent regardless of resolution.

At 3840x2160, the averages are 275 FPS on Low, 250 FPS on Medium, 221 FPS on High, and 179 FPS on Ultra. The Medium preset has a minimum of 212 FPS and a maximum of 287 FPS, with a spread of 75 FPS. This is the tightest spread in the dataset, which is logical because the GPU is under the most load and is less likely to be interrupted by CPU hiccups. The drop from Low to Ultra at 4K is 96 FPS, a 35% reduction, which is again consistent with the other resolutions. The data shows a very predictable scaling pattern: each step up in settings costs roughly 12-15% of the frame rate, and each step up in resolution costs roughly 30-35% of the frame rate. This predictability is a sign of a well-behaved game and stable hardware.

Settings Recommendations

For the best experience, the data points to the Medium preset as the sweet spot. At 1080p Medium, the system delivers 662 FPS with a minimum of 563 FPS, which is far above any display refresh rate. At 1440p Medium, it delivers 442 FPS with a minimum of 376 FPS, and at 4K Medium, it delivers 250 FPS with a minimum of 212 FPS. The Medium preset appears to be the most stable in terms of frame pacing, as it is the only setting with recorded min/max values across all resolutions. This stability is preferable for a smooth experience, even if the average FPS is lower than Low settings.

The Ultra preset is not recommended for competitive play because the frame rates, while high, are the lowest in the dataset. At 4K Ultra, the average is 179 FPS, which is still excellent, but the lack of min/max data means we cannot assess its frame time consistency. The High preset offers a middle ground, but the Medium preset provides a better balance of visual quality and performance. For users with a 144Hz monitor, the Medium preset at 4K is the best choice, as it maintains an average of 250 FPS with a minimum above 200 FPS. For users with a 240Hz monitor, the Medium preset at 1440p is ideal, with an average of 442 FPS. At 1080p, any preset will exceed 240Hz, but Medium is recommended for its stability. The data does not show any benefit to choosing Low settings, as the frame rate gains are not worth the visual degradation, and the system is never struggling to maintain high frame rates.
