Roblox

Roblox is a sandbox title that scales unusually well with high-end hardware, and the Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 5090 produces extraordinary frame rates across the board. The data shows a system that is never truly stressed at any resolution or setting, delivering playable performance even at 4K Ultra where the average FPS remains well above the refresh rates of most displays. This combination consistently pushes frame rates into triple-digit territory, with the lowest recorded average being 182.7 FPS at the most demanding configuration.

Resolution Scaling

The performance drop from 1080p to 4K reveals a system that is heavily GPU-bound at lower resolutions but transitions to a more balanced workload as pixel count increases. At 1080p High, the average FPS is 590.6, while at 1440p High it falls to 394.8, and at 4K High it settles at 223.4. The scaling from 1080p to 1440p represents a 33% reduction in frame rate, while moving from 1440p to 4K incurs a 43% drop. This pattern indicates that at 1080p, the RTX 5090 is not the limiting factor; the CPU is likely holding the system back from achieving even higher numbers. At 4K, the GPU begins to take on a more significant role, but even then, the frame rates are so high that the system is clearly not being pushed to its limits.

The delta between Low and Ultra settings at each resolution reinforces this analysis. At 1080p, the spread from Low (739.2 FPS) to Ultra (481.4 FPS) is a 35% performance penalty. At 1440p, the same comparison shows Low at 491.1 FPS versus Ultra at 322.8 FPS, a 34% penalty. At 4K, Low produces 277.9 FPS while Ultra drops to 182.7 FPS, a 34% penalty. The consistency of this percentage across resolutions suggests that the game's settings scale predictably, with the GPU handling the increased workload efficiently. However, the absolute numbers indicate that even at 4K Ultra, the RTX 5090 has substantial headroom remaining.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor from the Raptor Lake Refresh architecture, running on the Intel Socket 1700 platform. Its base clock of 3.40 GHz and boost clock of 5.60 GHz provide the single-thread performance necessary for Roblox's engine, which is known to be sensitive to core speed. The CPU's benchmark results support its capability: a Cinebench R23 multi-core score of 44557 and a single-core score of 6290 place it in the 96th percentile against all CPUs. This strong single-thread performance is critical for a game like Roblox, where physics and scripting often run on a limited number of threads.

The data indicates that at 1080p, the CPU is the primary bottleneck. With an average of 739.2 FPS at Low settings, the frame rate is approaching what the game engine can realistically deliver. The RTX 5090 is capable of far more, but the CPU's ability to feed the GPU becomes the constraint. At 4K, the GPU takes over as the limiting component, but the CPU still provides enough throughput to maintain frame rates above 180 FPS. The processor's 33 MB of shared L3 cache and 2 MB per-core L2 cache help reduce latency in data-heavy scenarios, which is beneficial for Roblox's blocky but computationally intensive worlds.

How This Combo Ranks

This specific combination of the Intel Core i7-14700KF and NVIDIA GeForce RTX 5090 ranks 25th out of 1800 tested combos in Roblox. This top 1.4% placement is notable because it places this system ahead of many other pairings that might feature more expensive CPUs or GPUs. The ranking suggests that the balance between this particular CPU and GPU is well-suited for Roblox, which is not always the case with high-end components that may be overkill for less demanding titles.

The CPU's nearest rivals in the general benchmark database include the Intel Core i7-14700K with an average score of 70074 and a delta of 0%, the AMD EPYC 9115 at 69887 with a 0.3% delta, the AMD Ryzen 9 9950X at 70420 with a -0.4% delta, and the Intel Xeon Platinum 8270 at 71056 with a -1.3% delta. These small percentage differences indicate that the i7-14700KF is in a tightly contested performance bracket, yet its combination with the RTX 5090 still achieves a top-25 finish in Roblox. The GPU's nearest rivals, including the RTX 5090 D at 84241 (0.1% delta) and the RTX 5050 Mobile at 84171 (0.2% delta), show that the desktop RTX 5090 is at the top of its class, but the overall combo ranking benefits from the synergistic pairing.

Measured FPS Breakdown

The measured frame rates provide a complete picture of performance across all configurations. At 1080p, the average FPS ranges from 739.2 at Low settings to 668.9 at Medium, 590.6 at High, and 481.4 at Ultra. These numbers are exceptionally high, with even the Ultra setting producing over 480 FPS. At 1440p, the averages are 491.1 at Low, 447 at Medium, 394.8 at High, and 322.8 at Ultra. The drop from 1080p to 1440p is significant but not drastic, with the Ultra setting still delivering over 320 FPS. At 4K, the averages are 277.9 at Low, 253.2 at Medium, 223.4 at High, and 182.7 at Ultra. Even the most demanding configuration, 4K Ultra, maintains an average above 180 FPS, which is far beyond what most displays can refresh.

The data reveals a consistent pattern: each step from Low to Ultra at any given resolution reduces frame rates by a similar percentage. The difference between Low and High at 1080p is 20%, while the difference between High and Ultra is an additional 18%. This scaling indicates that the game's graphical settings have a moderate impact on performance, but the underlying hardware is so powerful that the impact is only noticeable at the extremes. For users with high-refresh-rate monitors, the 1440p and 4K results are particularly compelling, as even 4K Ultra provides frame rates that exceed the capabilities of most current displays.

GPU Role

The NVIDIA GeForce RTX 5090 is the flagship of the GeForce 50-series, built on the Blackwell 2.0 architecture with a 5 nm process from TSMC. It features 32 GB of GDDR7 memory on a 512-bit bus, providing a memory bandwidth of 1.79 TB/s. The GPU's base clock is 2017 MHz with a boost clock of 2407 MHz, and its memory operates at 1750 MHz with 28 Gbps effective speed. These specifications are reflected in its benchmark results, including a 3DMark Steel Nomad DX12 score of 14411 and a Geekbench OpenCL score of 380114, placing it in the 94th percentile against all GPUs.

In Roblox, the RTX 5090's role is primarily to handle the game's rendering, which includes complex lighting and shadow effects that can be demanding even for a block-based art style. The GPU's 21760 shading units and 176 ROPs contribute to its ability to sustain high frame rates at 4K, where the pixel fill rate becomes a factor. The 423.6 GPixel/s pixel rate and 1,636.8 GTexel/s texture rate are more than sufficient for Roblox's needs. The GPU's performance in this game is characterized by its ability to maintain frame rates that are limited only by the CPU at lower resolutions and by its own capabilities at higher ones. The data shows that even at 4K Ultra, the RTX 5090 is not fully utilized, leaving headroom for future game updates or more demanding user-created content.
