Roblox

Roblox is not a demanding title, but the data for the Intel Core i7-13700K and NVIDIA GeForce RTX 4090 combination shows extreme performance headroom at every setting. The measured frames per second (FPS) range from 713.6 at 1080p Low down to 172.7 at 4K Ultra, indicating that this hardware is heavily overqualified for the game’s typical workloads. The benchmark results place this combo at rank 43 out of 1800 measured configurations, putting it in the top 2.4% of all tested systems for this specific title. This page breaks down the measured performance data, the role of each component, and what the scaling patterns reveal about the system's behavior.

GPU Role

The NVIDIA GeForce RTX 4090 is the dominant component in this pairing, and its specifications explain the high FPS numbers. It features 24 GB of GDDR6X memory on a 384-bit bus, providing a bandwidth of 1.01 TB/s. This vast memory pool and bandwidth ensure that texture streaming and asset loading are not bottlenecks, even at 4K resolution. The GPU’s core configuration includes 16384 shading units, 512 texture mapping units, and 176 raster output units. Its boost clock is rated at 2520 MHz, with a base clock of 2235 MHz.

In the context of Roblox, the GPU's raw compute power is the primary driver of the high frame rates. The data shows that at 1080p Low, the average FPS is 713.6, which is a scenario where the CPU might be the limiting factor, but the GPU still delivers massive performance. The GPU's PassMark G3D score is 38194, placing it in the 91st percentile of all GPUs. The compute capability is further evidenced by its FP32 performance of 82.58 TFLOPS, which is overkill for a game like Roblox but explains why even at 4K Ultra, the system maintains an average of 172.7 FPS.

The VRAM capacity is not a concern here; 24 GB is far more than Roblox will ever require. The data indicates that the limiting factor at lower resolutions is not the GPU memory or bandwidth but rather the game's engine and CPU performance. At higher resolutions, the GPU's shading units and pixel rate (443.5 GPixel/s) come into play, yet the FPS remains exceptionally high. The benchmark results indicate that the RTX 4090 is never the bottleneck in this configuration; instead, the game's engine and CPU serialization cap the frame rate at lower settings.

Resolution Scaling

The measured data reveals a clear pattern of diminishing returns as resolution increases, but the absolute FPS remains high across all tested points. At 1080p Low, the average is 713.6 FPS. Moving to 1440p Low, the average drops to 478.6 FPS, a 32.9% decrease. At 4K Low, the average is 271.9 FPS, another 43.2% drop from 1440p. This scaling suggests that while the GPU is powerful, the game's rendering pipeline becomes more demanding at higher pixel counts, but the system still has plenty of headroom.

The pattern is similar at Ultra settings. 1080p Ultra yields 464.3 FPS, 1440p Ultra drops to 310.8 FPS (a 33.1% decrease), and 4K Ultra falls to 172.7 FPS (a 44.4% decrease from 1440p). The consistent percentage drops across settings indicate that the resolution scaling is relatively linear, which points to the GPU being the primary driver of performance changes when resolution increases. However, the absolute numbers are so high that even the lowest measured result (172.7 FPS at 4K Ultra) is far above the refresh rate of most monitors.

The data suggests that at 1080p, the CPU is likely the limiting factor, as the FPS difference between Low and High settings is relatively small (713.6 vs 574.4 FPS). At 4K, the GPU becomes more of a factor, but the RTX 4090 still manages to deliver over 170 FPS at the highest preset. This indicates that for Roblox, the system is balanced in a way that the CPU caps performance at low resolutions, while the GPU scales effectively with higher resolution demands.

Settings Recommendations

Based on the measured FPS rows, the optimal setting depends on the user's refresh rate and resolution. For 1080p displays, the Low preset delivers 713.6 FPS, which is excessive for any standard monitor. The High preset at 574.4 FPS is still incredibly high and offers better visual quality. Given that even the Ultra preset at 1080p averages 464.3 FPS, users can comfortably max out settings at this resolution without any concern for playability.

At 1440p, the data shows that the High preset (383.3 FPS) is a strong middle ground, but the Ultra preset (310.8 FPS) is also perfectly playable. The Low preset (478.6 FPS) provides the highest frame rate, but the visual fidelity loss is not worth it when the High preset still offers over 380 FPS. For 4K, the High preset (215.7 FPS) remains above 200 FPS, making it the best balance of visual quality and performance. The Ultra preset (172.7 FPS) is still viable but represents a 19.9% performance hit compared to High.

The recommendation is to prioritize the High preset at any resolution, as it provides a significant visual upgrade over Medium (247.6 FPS at 4K) while maintaining frame rates above 200 FPS. The Low preset only makes sense for competitive play where every millisecond counts, but the difference between Low and High at 1080p is 139.2 FPS, which is not perceptible on most displays. The Ultra preset is only recommended for users with high-refresh-rate 4K monitors that can display over 170 FPS.

Measured FPS Breakdown

At 1920x1080, the average FPS values are as follows: Low settings produce 713.6 FPS, Medium produces 646.7 FPS, High produces 574.4 FPS, and Ultra produces 464.3 FPS. The spread between Low and Ultra is 249.3 FPS, showing that settings have a substantial impact even at this resolution.

At 2560x1440, the averages are: Low at 478.6 FPS, Medium at 430.7 FPS, High at 383.3 FPS, and Ultra at 310.8 FPS. The drop from Low to Ultra is 167.8 FPS, which is a smaller absolute difference than at 1080p but still significant.

At 3840x2160, the averages are: Low at 271.9 FPS, Medium at 247.6 FPS, High at 215.7 FPS, and Ultra at 172.7 FPS. The difference between Low and Ultra here is 99.2 FPS. The data shows that as resolution increases, the absolute impact of settings decreases, but the relative impact remains similar. For example, at 1080p, Ultra is 65.1% of Low's performance, and at 4K, Ultra is 63.5% of Low's performance.

The scaling from 1080p to 4K at the same settings shows the following: Low drops by 61.9% (from 713.6 to 271.9 FPS), Medium drops by 61.7% (from 646.7 to 247.6 FPS), High drops by 62.4% (from 574.4 to 215.7 FPS), and Ultra drops by 62.8% (from 464.3 to 172.7 FPS). This consistent ~62% drop indicates that the GPU's workload scales predictably with pixel count, and the system does not exhibit any unexpected bottlenecks at higher resolutions.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. It has 30 MB of shared L3 cache and uses the Raptor Lake architecture. In Roblox, the CPU's role is primarily to handle game logic, physics, and scripting, which are often single-threaded or lightly threaded tasks.

The benchmark data shows that the CPU excels in single-threaded performance, with a 3DMark single-thread score of 1136 and a Cinebench R23 single-core score of 5505. These scores are critical for Roblox, as the game engine often relies on a single main thread for many operations. The high boost clock of 5.40 GHz helps ensure that this thread is processed as quickly as possible. The multi-threaded scores are also strong (Cinebench R23 multicore score of 39000), but Roblox is unlikely to utilize all 16 cores effectively.

The CPU's 93rd percentile ranking among all CPUs indicates that it is a top-tier processor, but in this specific game, its performance is likely capped by the game's engine limitations rather than the CPU's capabilities. The measured FPS at 1080p Low (713.6 FPS) suggests that the CPU is able to feed the GPU with enough frames to reach that level, but the fact that the FPS drops significantly at higher resolutions (271.9 FPS at 4K Low) shows that the GPU is taking over the workload. The CPU's nearest rival, the Intel Core i7-13700KF, has an average benchmark score that is 0.1% lower, indicating that the KF variant (without integrated graphics) offers essentially identical performance. The AMD EPYC 4364P is 0.3% higher, and the AMD Ryzen 9 PRO 5945 is 0.5% lower, all within a tight margin. This suggests that for Roblox, the choice between these CPUs would not result in any noticeable FPS difference.
