Roblox

Roblox is notoriously light on the GPU, and this pairing of an Intel Core i5-14600K with an NVIDIA GeForce RTX 5090 D demonstrates that dynamic perfectly. The measured data shows a system capable of triple-digit frame rates at every resolution and settings combination, but the way those numbers scale reveals where the true bottleneck lies. This is a configuration built for extreme high-refresh-rate gaming, and the benchmark results confirm that it delivers, though not always in the way the raw hardware specs might suggest.

Resolution Scaling

The transition from 1080p to 4K shows a clear and predictable pattern of performance scaling, but the magnitude of the drop tells a story about component utilization. At 1920x1080 with High settings, this combo produces an average of 625 FPS. Moving to 2560x1440 at the same preset drops the average to 417 FPS, a reduction of approximately 33%. Stepping up again to 3840x2160 High yields 236 FPS, which is another 43% drop from the 1440p result. The total scaling from 1080p to 4K at High settings is a 62% reduction in average frame rate, from 625 down to 236 FPS.

The Low settings preset tells a similar story but with higher absolute numbers. At 1080p Low, the system hits an average of 776 FPS. At 1440p Low, that falls to 518 FPS, and at 4K Low, it drops to 293 FPS. The percentage drops between each resolution step are remarkably consistent, hovering around 33-43% per step. This consistency suggests that the scaling is driven primarily by pixel throughput demands on the RTX 5090 D, rather than any sudden shift in bottleneck behavior.

What is most telling about the limiting component is the gap between Low and High settings at each resolution. At 4K, the difference between Low (293 FPS) and High (236 FPS) is 57 FPS, or about 24%. At 1440p, the gap widens to 101 FPS (518 vs 417), and at 1080p it expands to 151 FPS (776 vs 625). This pattern indicates that as resolution drops, the CPU becomes more of a limiting factor, because the GPU has spare capacity that the processor cannot feed fast enough. The i5-14600K with its 14 cores and 20 threads is no slouch, but Roblox's engine is not known for heavy multi-threading, and the data suggests single-thread performance becomes the ceiling at lower resolutions.

The Ultra preset shows the steepest drop-off. At 1080p Ultra, the average is 507 FPS, which drops to 338 FPS at 1440p and then down to 191 FPS at 4K. The 4K Ultra result is the lowest measured on this page, and the scaling from 1080p to 4K at Ultra is a 62% reduction, nearly identical to the High preset's scaling. This suggests that the Ultra preset's additional effects are scaling proportionally with resolution, rather than introducing a new bottleneck.

The medium preset is the only one with min and max FPS data. At 4K Medium, the average is 267 FPS with a minimum of 227 and a maximum of 307. At 1440p Medium, the average climbs to 471 FPS with a min of 401 and max of 542. At 1080p Medium, the average reaches 706 FPS with a min of 600 and max of 812. The consistency of the min-to-max spread, roughly 30% across all three resolutions, indicates stable frame pacing without any sudden stutters or hitches.

Settings Recommendations

For players prioritizing maximum frame rate, the Low preset at 1080p delivers the highest measured average on this page at 776 FPS. However, this comes at the cost of visual fidelity. The data shows that the step from Low to Medium at 1080p costs 70 FPS on average (776 down to 706), which is a 9% reduction. That is a relatively small penalty for the visual improvement Medium typically provides over Low. The Medium preset also offers the only complete dataset with min and max frames, showing a minimum of 600 FPS at 1080p, which is still exceptionally high.

At 1440p, the Medium preset delivers 471 FPS average, which is 47 FPS higher than High (417 FPS) and 133 FPS higher than Ultra (338 FPS). The jump from Medium to High costs 54 FPS, while the jump from High to Ultra costs an additional 79 FPS. Given that most high-refresh-rate monitors top out at 360 Hz or 480 Hz, the Medium preset at 1440p provides more than enough headroom above any display's refresh rate, making the extra visual features of High or Ultra a matter of personal preference rather than competitive necessity.

For 4K gaming, the situation is different. The High preset at 236 FPS is the sweet spot for most users, as it clears the 240 Hz threshold that many high-end 4K displays use. The Medium preset at 267 FPS offers additional headroom, but the Ultra preset at 191 FPS falls below the 240 Hz mark. For those with 120 Hz or 144 Hz 4K displays, even the Ultra preset at 191 FPS is more than sufficient, and the visual quality gains may be worth the frame rate reduction.

The data suggests that for competitive play where frame rate is paramount, the Low preset at 1080p or 1440p is the choice, with 776 FPS and 518 FPS averages respectively. For a balance of visuals and performance, Medium at any resolution provides the best measured frame pacing, as evidenced by the min FPS figures. The Medium preset at 1080p has a minimum of 600 FPS, which is higher than the average of the High preset at the same resolution (625 FPS), indicating that Medium offers a more consistent experience than the average numbers alone suggest.

FAQ

Q: What is the highest average FPS measured on this page?

A: The highest average FPS is 776, achieved at 1920x1080 with the Low settings preset. This is significantly higher than the 4K Ultra result of 191 FPS, showing the performance range available from this combo.

Q: How does the 4K Ultra performance compare to 1080p Low?

A: The 4K Ultra preset produces an average of 191 FPS, which is 585 FPS lower than the 1080p Low result of 776 FPS. This represents a 75% reduction in average frame rate when moving from the lightest to the heaviest settings configuration.

Q: Is the RTX 5090 D the bottleneck at 1080p?

A: No. The data shows that at 1080p, the difference between Low (776 FPS) and High (625 FPS) is 151 FPS, but the scaling pattern suggests the CPU becomes the limiting factor as resolution drops. The GPU has significant headroom at 1080p that the i5-14600K cannot fully utilize in Roblox.

Q: What is the minimum FPS recorded in any configuration?

A: The only configuration with min FPS data is the Medium preset, which shows a minimum of 600 FPS at 1080p, 401 FPS at 1440p, and 227 FPS at 4K. The 4K Medium minimum of 227 FPS is the lowest recorded minimum on this page.

Q: How does the combo rank among all tested configurations in Roblox?

A: This combo ranks first out of 3010 tested combinations in Roblox. This top ranking is consistent with the measured frame rates, which exceed what most displays can even show.

Q: Does the Ultra preset provide the best frame pacing?

A: No. The Ultra preset has the lowest average FPS at every resolution (507 at 1080p, 338 at 1440p, 191 at 4K). The Medium preset provides the most complete data with min and max values, and its minimums are higher than the averages of the High preset at the same resolution.

Measured FPS Breakdown

At 1920x1080, the full range of settings produces a spread from 507 FPS to 776 FPS. The Low preset leads with 776 FPS average, followed by Medium at 706 FPS, High at 625 FPS, and Ultra at 507 FPS. The Medium preset shows a minimum of 600 FPS and a maximum of 812 FPS. This means even the most demanding 1080p preset, Ultra, maintains an average above 500 FPS, which exceeds the refresh rate of virtually any gaming monitor available.

Moving to 2560x1440, the averages are 518 FPS for Low, 471 FPS for Medium, 417 FPS for High, and 338 FPS for Ultra. The Medium preset again provides the only min and max data, with a minimum of 401 FPS and a maximum of 542 FPS. The drop from 1080p to 1440p is consistent across all presets, averaging about 33% reduction. The lowest 1440p result, Ultra at 338 FPS, still exceeds the refresh rate of all but the most extreme 360 Hz displays.

At 3840x2160, the averages are 293 FPS for Low, 267 FPS for Medium, 236 FPS for High, and 191 FPS for Ultra. The Medium preset shows a minimum of 227 FPS and a maximum of 307 FPS. This is the first resolution where any preset falls below 200 FPS, with Ultra averaging 191 FPS. Even so, the Low preset at 293 FPS and Medium at 267 FPS provide ample performance for 4K gaming at high refresh rates, and the High preset at 236 FPS clears the 240 Hz mark that many 4K high-refresh displays target.

The difference between the lowest and highest settings at each resolution grows as resolution decreases. At 4K, the Low-to-Ultra spread is 102 FPS (293 to 191). At 1440p, the spread is 180 FPS (518 to 338). At 1080p, the spread is 269 FPS (776 to 507). This widening gap at lower resolutions reinforces that the CPU becomes the limiting factor as the GPU has less work to do per frame.

How This Combo Ranks

This combination of Intel Core i5-14600K and NVIDIA GeForce RTX 5090 D ranks first overall in Roblox, out of 3010 tested combos. This top placement is not surprising given the measured frame rates, which show no configuration dipping below 191 FPS average even at the most demanding 4K Ultra settings. The rank reflects the combination of a high-end CPU and the flagship GPU from the GeForce 50-series, both of which are currently active production parts.

The CPU's individual standing is 90th percentile among all processors, with an average benchmark score of 48618. Its nearest rivals include the Intel Xeon Gold 5318H with a score of 48698 (a 0.2% difference), the AMD EPYC 4345P at 48470 (0.3% difference), the Intel Core Ultra 5 245HX at 48287 (0.7% difference), and the Intel Core Ultra 5 245 at 48995 (a -0.8% difference). These rivals are within a single percentage point of the i5-14600K, indicating that the CPU's performance is closely matched by several other parts, but none of them are paired with the RTX 5090 D in this test configuration.

The GPU's standing is 92nd percentile among all graphics cards, with an average benchmark score of 77712. Its nearest rivals are the AMD Radeon RX 6650M XT at 76904 (a 1.1% difference), the AMD Radeon RX 6850M XT at 78940 (-1.6% difference), the NVIDIA Tesla P100 PCIe 12 GB at 79396 (-2.1% difference), and the NVIDIA Tesla P100 PCIe 16 GB at 79605 (-2.4% difference). These rivals are all within a few percentage points in average benchmark score, yet the RTX 5090 D's performance in Roblox is far beyond what those scores might suggest, reinforcing that Roblox is not a GPU-bound title at typical resolutions.

The number one rank out of 3010 combos indicates that no other tested pairing of CPU and GPU produces higher frame rates in this game. The practical implication is that for Roblox, this configuration represents the ceiling of measured performance. No other combination in the database has achieved better results, which makes this the reference point for maximum Roblox performance.

CPU Role

The Intel Core i5-14600K is a 14-core, 20-thread processor based on the Raptor Lake architecture, built on Intel's 10 nm process. Its base clock is 3.50 GHz with a boost clock of 5.30 GHz. The cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 24 MB of shared L3 cache. The processor supports both DDR4 and DDR5 memory in dual-channel configuration, and it has a 125 W TDP with an unlocked multiplier for overclocking.

In synthetic benchmarks, the i5-14600K scores 24491 in Cinebench R23 multi-core and 2064 in single-core, along with 13709 in Cinebench R20 multi-core and 1935 in single-core. Its Geekbench scores are 16673 multi-core and 2491 single-core. Passmark results show a multi-thread score of 38682 and a single-thread score of 4270. These figures place the CPU at the 90th percentile overall, with an average benchmark score of 48618.

For Roblox specifically, the CPU's role is critical because the game is known to be lightly threaded. The measured FPS data shows that at 1080p Low, the system produces 776 FPS, which is far beyond what the GPU alone would demand. The fact that the 4K Low result (293 FPS) is less than half the 1080p Low result (776 FPS) suggests that the CPU is capable of feeding frames much faster than the GPU can render them at high resolution. At 1080p, the CPU is likely the primary limiter, as indicated by the widening gap between Low and Ultra settings as resolution decreases.

The single-core performance of 2064 in Cinebench R23 and 4270 in Passmark is what matters most for Roblox. The boost clock of 5.30 GHz provides the high single-threaded throughput that this game favors. The 14 cores and 20 threads are more than sufficient for Roblox's modest multi-threading, and the 24 MB of L3 cache helps with the game's asset streaming. The combination of high boost clock and strong single-core benchmark results aligns with the measured FPS data, which shows the CPU holding up its end of the pairing even at 1080p where frame rates exceed 700 FPS.
