# Roblox with Intel Core i5-14600KF + NVIDIA GeForce RTX 5090 D

The Intel Core i5-14600KF paired with the NVIDIA GeForce RTX 5090 D delivers exceptional performance in Roblox, ranking first out of 3,010 tested combos. This configuration achieves triple-digit frame rates across every resolution and settings combination tested, with the 1080p Low preset reaching an average of 776 FPS—a figure that dwarfs the demands of most competitive play. The data reveals a system that is overwhelmingly GPU-bound at higher resolutions but transitions to CPU-bound behavior at 1080p, where the i5-14600KF's strong single-thread performance becomes the limiting factor. This analysis breaks down the measured results, contextualizes them against rival hardware, and answers common questions about this pairing.

Resolution Scaling

The frame rate scaling from 1080p to 4K in Roblox follows a predictable pattern that highlights where the bottleneck shifts between components. At 1080p High settings, the combo averages 625 FPS, while 1440p High drops to 417 FPS—a reduction of approximately 33%. Moving to 4K High brings the average down to 236 FPS, which is about 62% lower than the 1080p result. This steep decline indicates that the RTX 5090 D's rendering workload increases substantially with resolution, but the absolute numbers remain far above playable thresholds.

Examining the Low preset tells a similar story with even higher absolute figures. At 1080p Low, the system achieves 776 FPS average, dropping to 518 FPS at 1440p and 293 FPS at 4K. The percentage drops between resolutions are consistent: 1440p represents a 33% decrease from 1080p, and 4K represents a 43% decrease from 1440p. This pattern suggests that even at Low settings, the GPU is still managing a significant portion of the rendering load, though the CPU's influence becomes more apparent at the lower resolution extreme.

The Medium preset results, which include minimum and maximum frame data, show the same scaling trend. At 1080p Medium, the average is 706 FPS with a minimum of 600 FPS and maximum of 812 FPS. At 1440p Medium, the average falls to 471 FPS with a minimum of 401 FPS and maximum of 542 FPS. The 4K Medium result averages 267 FPS with a minimum of 227 FPS and maximum of 307 FPS. The minimum frame rates scale proportionally with averages, indicating consistent frame pacing rather than occasional stutters.

The Ultra preset delivers the lowest frame rates of any settings tier, as expected. At 1080p Ultra, the average is 507 FPS; at 1440p Ultra, it drops to 338 FPS; and at 4K Ultra, it bottoms out at 191 FPS. These numbers still represent extremely smooth gameplay, but the 62% reduction from 1080p to 4K Ultra demonstrates that Roblox's higher graphical presets impose a meaningful rendering cost on even the most powerful consumer GPU available.

The scaling behavior reveals that this combination is never truly CPU-limited in a way that hurts playability. Even at 4K Ultra with the lowest measured average of 191 FPS, the system remains far above the refresh rates of most monitors. The data suggests that resolution scaling in Roblox is primarily a GPU workload, with the RTX 5090 D's massive compute resources absorbing the increased pixel count without collapsing frame rates.

GPU Role

The NVIDIA GeForce RTX 5090 D is built on the Blackwell 2.0 architecture using a 5 nm process at TSMC, with a chip containing 92,200 million transistors on a 750 mm² die. Its base clock runs at 2017 MHz with a boost clock of 2407 MHz, and the memory operates at 1750 MHz with 28 Gbps effective speed. The 32 GB of GDDR7 memory across a 512-bit bus provides 1.79 TB/s of bandwidth—an enormous pool of memory bandwidth that proves relevant even for a game like Roblox, which is not typically associated with demanding graphics requirements.

The GPU's 21,760 shading units, 680 texture mapping units, and 176 raster output pipelines deliver raw throughput that translates directly to the frame rates observed in these tests. The pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s explain why the card can push hundreds of frames per second at 4K resolution. The FP32 compute of 104.8 TFLOPS provides ample headroom for Roblox's physics and rendering workloads, even though the game is not known for pushing GPUs to their limits.

In Roblox specifically, the RTX 5090 D's performance is characterized by its ability to maintain high frame rates even as resolution and settings increase. The 4K Ultra average of 191 FPS versus 1080p Ultra at 507 FPS shows a 62% performance drop, which is a larger proportional decrease than the 41% drop seen between 4K High and 1080p High. This indicates that the Ultra preset includes effects that scale more aggressively with resolution, likely related to the GPU's shading and texture processing capabilities.

The GPU's benchmark scores place it in the 92nd percentile of all GPUs, with an average benchmark score of 77,712. Its nearest rivals in average score include the AMD Radeon RX 6850M XT at 78,940 (1.6% higher), the NVIDIA Tesla P100 PCIe 12 GB at 79,396 (2.1% higher), and the NVIDIA Tesla P100 PCIe 16 GB at 79,605 (2.4% higher). Interestingly, the AMD Radeon RX 6650M XT scores 76,904, which is 1.1% lower than the RTX 5090 D. These comparisons suggest that while the RTX 5090 D is powerful, its raw compute benchmark scores are closely matched by some workstation and mobile parts, though Roblox's actual gaming workload may favor the newer architecture's features.

How This Combo Ranks

The Core i5-14600KF and RTX 5090 D combination ranks first out of 3,010 tested combos in Roblox, placing it at the very top of the database. This top ranking is particularly noteworthy given the CPU's mid-range positioning within Intel's 14th Gen lineup—the i5-14600KF is not the flagship processor, yet it achieves the best result when paired with the RTX 5090 D. The data suggests that Roblox's performance ceiling in this configuration is determined more by the GPU's raw capabilities than by CPU choice, at least at higher resolutions.

The RTX 5090 D alone sits in the 92nd percentile of all GPUs, while the i5-14600KF sits in the 90th percentile of all CPUs. When combined in Roblox, the duo surpasses what either component's individual percentile might suggest, indicating that the pairing is well-balanced for this particular title. The GPU's average benchmark score of 77,712 and the CPU's average benchmark score of 49,394 both contribute to a combination that outperforms 3,009 other tested pairings.

The CPU's nearest rivals in overall benchmark score provide context for its contribution. The AMD Ryzen 9 7900 scores 49,228, which is 0.3% lower than the i5-14600KF's 49,394. The AMD Ryzen 7 PRO 5755G scores 49,196, a 0.4% deficit. The Intel Core Ultra 5 245 scores 48,995, lagging by 0.8%. The AMD Ryzen AI Max+ 388 scores 49,796, which is 0.8% higher. These tight margins show that the i5-14600KF is competitive with a range of modern processors, though none of these rivals were necessarily tested with the same RTX 5090 D in Roblox.

The GPU's rival comparisons show similar clustering. The AMD Radeon RX 6650M XT trails by 1.1%, while the AMD Radeon RX 6850M XT leads by 1.6%. The NVIDIA Tesla P100 PCIe 12 GB and 16 GB variants lead by 2.1% and 2.4% respectively. These small percentage differences in synthetic benchmarks do not necessarily translate to gaming performance, and the RTX 5090 D's first-place ranking in Roblox demonstrates that its real-world gaming capabilities exceed what its compute benchmarks might suggest.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. The Low preset averages 776 FPS, making it the fastest configuration tested. Medium averages 706 FPS with a minimum of 600 FPS and maximum of 812 FPS. High averages 625 FPS. Ultra averages 507 FPS, which is the lowest 1080p result but still far above typical display refresh rates. The spread between Low and Ultra at 1080p is 269 FPS, representing a 35% performance penalty for the highest quality settings.

At 2560x1440, the frame rates remain exceptionally high. Low averages 518 FPS, Medium averages 471 FPS with a minimum of 401 FPS and maximum of 542 FPS, High averages 417 FPS, and Ultra averages 338 FPS. The transition from 1080p to 1440p costs between 33% and 34% of performance depending on the preset, showing a consistent scaling factor. The Medium preset's 401 FPS minimum ensures that even momentary frame drops stay well above the threshold for smooth gameplay.

At 3840x2160, the system still produces triple-digit averages across all settings. Low averages 293 FPS, Medium averages 267 FPS with a minimum of 227 FPS and maximum of 307 FPS, High averages 236 FPS, and Ultra averages 191 FPS. The 4K Ultra result represents the most demanding configuration tested, yet it still exceeds the 144 Hz refresh rate common on high-end monitors. The Medium preset's minimum of 227 FPS indicates that even worst-case scenarios remain highly playable.

Comparing settings tiers at each resolution reveals that Roblox's graphical presets have a consistent impact. At 1080p, Ultra is 35% slower than Low. At 1440p, Ultra is 35% slower than Low. At 4K, Ultra is 35% slower than Low. This consistency suggests that the settings presets scale computational load proportionally regardless of resolution, and the RTX 5090 D handles the increased workload without disproportionate frame rate penalties.

CPU Role

The Intel Core i5-14600KF is a 14-core, 20-thread processor based on the Raptor Lake architecture, manufactured on Intel's 10 nm process. It features 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 24 MB of shared L3 cache. Its base clock of 3.50 GHz boosts up to 5.30 GHz, and it supports both DDR4 and DDR5 memory in a dual-channel configuration. The CPU's 125 W TDP and unlocked multiplier make it a flexible choice for various system builds, though this analysis focuses on its gaming performance in Roblox.

In Roblox, the CPU's role is most evident at 1080p, where frame rates reach their absolute maximum. The 776 FPS average at 1080p Low suggests that the processor's single-thread performance is capable of feeding the GPU with enough draw calls and physics calculations to sustain extremely high frame rates. The Geekbench single-core score of 2,445 and Cinebench R23 single-core score of 4,594 indicate strong single-threaded capability, which is critical for Roblox's largely single-threaded game loop.

The CPU's multi-threaded performance provides additional headroom for background tasks and any Roblox workloads that leverage multiple cores. The Cinebench R23 multi-core score of 32,544 and Geekbench multi-core score of 17,085 show that the processor can handle parallel workloads efficiently. The PassMark multi-thread score of 38,697 further confirms this capability, though Roblox itself is unlikely to stress all 20 threads simultaneously.

The i5-14600KF's 90th percentile ranking among all CPUs places it in the upper tier of processors, and its average benchmark score of 49,394 is competitive with the AMD Ryzen 9 7900 (49,228, 0.3% lower) and AMD Ryzen 7 PRO 5755G (49,196, 0.4% lower). The Intel Core Ultra 5 245 trails by 0.8%, while the AMD Ryzen AI Max+ 388 leads by 0.8%. These tight margins indicate that the i5-14600KF is well-positioned within the current CPU landscape.

In the context of this Roblox testing, the CPU's influence appears secondary to the GPU's capabilities. The consistent 35% performance difference between Low and Ultra presets across all resolutions suggests that the GPU is the primary determinant of frame rates, with the CPU providing enough throughput to avoid becoming a bottleneck. The fact that this combo ranks first overall in Roblox, despite the CPU being a mid-range part, underscores that Roblox's performance ceiling is more contingent on GPU power than on having the absolute fastest processor available.
