Roblox

Roblox is an unusual title for a high-end hardware analysis because its visual demands are modest, yet the measured frame rates with the Intel Core i7-13700K and NVIDIA GeForce RTX 5070 reveal a system that is heavily overqualified for the workload. The data shows a combination that delivers exceptionally high average FPS across all tested resolutions and settings, with the scaling patterns indicating that the CPU becomes the primary limiting factor at lower resolutions while the GPU takes over at 4K. This analysis walks through the measured results, the role of each component, and how this specific pairing ranks within the broader database of tested configurations.

Resolution Scaling

The measured FPS data for Roblox shows a clear and predictable scaling pattern as resolution increases from 1920x1080 to 3840x2160. At 1080p with Low settings, the average frame rate is 537 FPS, which drops to 358 FPS at 1440p and further to 203 FPS at 4K. This represents a 62% reduction in average FPS from 1080p to 4K. The pattern is consistent across all settings presets: High settings produce 432 FPS at 1080p, 288 FPS at 1440p, and 163 FPS at 4K, a 62% drop as well. Medium settings show 489 FPS at 1080p, 326 FPS at 1440p, and 184 FPS at 4K, a 62% reduction. Ultra settings yield 350 FPS at 1080p, 234 FPS at 1440p, and 132 FPS at 4K, a 62% decrease.

The fact that the percentage drop from 1080p to 4K is nearly identical across all settings presets (62%) suggests that the scaling is primarily resolution-driven rather than settings-driven. In typical GPU-bound scenarios, higher settings would amplify the resolution penalty because the GPU has to do more work per pixel. Here, the consistent 62% reduction indicates that the RTX 5070 is not the limiting factor even at 4K Ultra, where the average FPS remains at 132. The data suggests that the CPU, with its 16 cores and 24 threads, is keeping up adequately at all resolutions, but the frame rate ceiling at 1080p is constrained by the game engine's single-threaded performance or other software limitations rather than raw graphics throughput.

Looking at the delta between 1080p and 1440p, the drop is roughly 33-35% across all settings (e.g., Low goes from 537 to 358, a 33% drop; Ultra goes from 350 to 234, a 33% drop). The drop from 1440p to 4K is more severe, around 43-44% (e.g., High goes from 288 to 163, a 43% drop). This non-linear scaling is typical of a system where the GPU becomes progressively more involved as pixel count increases, but even at 4K, the absolute numbers are so high that the limiting component is unlikely to be the GPU in any practical sense. Instead, the data points to the CPU and game engine as the primary constraints, particularly at 1080p where the RTX 5070 is essentially idle waiting for the next frame to render.

FAQ

Q: What is the average FPS at 1440p with High settings?

A: The measured average FPS is 288 at 2560x1440 with High settings.

Q: How does the RTX 5070's 12 GB of GDDR7 memory affect Roblox performance?

A: The 12 GB VRAM is far more than Roblox requires, and the data shows no VRAM-related bottlenecks at any resolution or settings level. The GPU's 672.0 GB/s bandwidth and 192-bit bus are more than sufficient for the game's relatively simple textures and geometry.

Q: What is the lowest average FPS recorded in the entire dataset?

A: The lowest average FPS is 132, which occurs at 3840x2160 with Ultra settings. This is still a very high frame rate for any game, let alone a sandbox title.

Q: Is the Intel Core i7-13700K a bottleneck for the RTX 5070 in Roblox?

A: At 1080p, the data suggests the CPU is the limiting factor, as the average FPS of 537 at Low settings is extremely high but does not scale linearly with the GPU's capability. At 4K, the CPU is less of a constraint, but the frame rates remain high enough that the bottleneck is not problematic.

GPU Role

The NVIDIA GeForce RTX 5070 plays a crucial role in Roblox, but the data indicates that its full capabilities are rarely tested. The GPU has 12 GB of GDDR7 memory, a 192-bit bus, and 672.0 GB/s of bandwidth. Its base clock is 2325 MHz with a boost clock of 2512 MHz, and it features 6144 shading units, 192 texture mapping units, and 80 raster output units. The GPU also has 48 ray tracing cores and 192 tensor cores, though Roblox does not heavily utilize these features.

The measured FPS data shows that the RTX 5070 is capable of delivering over 500 FPS at 1080p Low settings, which is far beyond the refresh rate of most monitors. At 4K Ultra, the average FPS drops to 132, which is still well above the 60 FPS threshold for smooth gameplay. The GPU's memory bandwidth of 672.0 GB/s is likely overkill for Roblox, as the game does not require large texture loads or complex shader operations. The 12 GB VRAM is also more than sufficient, even at 4K with Ultra settings, where the game's assets are unlikely to exceed 2-3 GB.

The GPU's role becomes more apparent when examining the scaling from Low to Ultra settings at each resolution. At 1080p, the difference between Low (537 FPS) and Ultra (350 FPS) is 187 FPS, a 35% reduction. At 4K, the difference between Low (203 FPS) and Ultra (132 FPS) is 71 FPS, a 35% reduction as well. This consistent percentage drop suggests that the GPU is handling the additional settings workload proportionally, but the absolute numbers are so high that the GPU is never the primary bottleneck. The RTX 5070's performance is more than adequate for Roblox, and the data suggests that the system would maintain high frame rates even in complex user-generated worlds with many objects and effects.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of how the Intel Core i7-13700K and NVIDIA GeForce RTX 5070 perform in Roblox across three resolutions and four settings presets. At 1920x1080, the lowest average FPS is 350 at Ultra settings, while the highest is 537 at Low settings. Medium settings produce 489 FPS on average, with a minimum of 415 and a maximum of 562. High settings yield 432 FPS on average. This resolution shows the highest frame rates in the dataset, with all presets exceeding 350 FPS.

At 2560x1440, the average FPS ranges from 234 at Ultra settings to 358 at Low settings. Medium settings produce 326 FPS on average, with a minimum of 277 and a maximum of 375. High settings yield 288 FPS on average. The 1440p results show a clear step down from 1080p, with the Ultra preset barely staying above 200 FPS at 234 FPS average.

At 3840x2160, the average FPS ranges from 132 at Ultra settings to 203 at Low settings. Medium settings produce 184 FPS on average, with a minimum of 157 and a maximum of 212. High settings yield 163 FPS on average. The 4K results represent the lowest frame rates in the dataset, but they are still exceptionally high for a game like Roblox. Even the most demanding preset at the highest resolution produces an average of 132 FPS, which is well above the 60 FPS target for most displays.

The data also shows that the Medium settings preset is the only one with recorded minimum and maximum FPS values. At 1080p Medium, the minimum FPS is 415 and the maximum is 562, indicating a range of 147 FPS. At 1440p Medium, the minimum is 277 and the maximum is 375, a range of 98 FPS. At 4K Medium, the minimum is 157 and the maximum is 212, a range of 55 FPS. This narrowing range at higher resolutions suggests that the frame time consistency improves as the GPU becomes more loaded, which is a common phenomenon in games where CPU-side frame generation can cause variability.

How This Combo Ranks

The Intel Core i7-13700K and NVIDIA GeForce RTX 5070 combination ranks 789 out of 3711 tested configurations in Roblox, placing it in the top 21% of all combos in the database. This is a strong ranking, though not a top-tier one, which is noteworthy given the high absolute frame rates measured. The ranking suggests that many other combinations achieve even higher frame rates in Roblox, likely due to the game's heavy reliance on CPU single-threaded performance rather than GPU capability.

The CPU's benchmark data provides context for this ranking. The Core i7-13700K has an average benchmark score of 46881 and ranks in the 89th percentile of all CPUs. Its nearest rivals include the AMD Ryzen 9 5900 (deltaPct -0.2), AMD Ryzen AI 9 HX PRO 375 (deltaPct -0.3), AMD Ryzen 9 7845HX (deltaPct 0.5), and Intel Xeon w3-2535 (deltaPct 0.5). These small deltas indicate that the CPU's performance is well within the expected range for its class.

The GPU's ranking is slightly lower, with a percentile of 82 and an average benchmark score of 40377. Its nearest rivals include the AMD Radeon Pro 580 (deltaPct 0.1), AMD Radeon Pro WX 7100 (deltaPct 0.8), AMD Radeon Pro 5300 (deltaPct -1.2), and NVIDIA RTX A500 Mobile (deltaPct 2). The RTX 5070's benchmark scores, such as 5077 in 3DMark Steel Nomad DX12 and 29137 in Passmark G3D, are strong but not exceptional in the context of the full GPU database.

The combo's rank of 789 out of 3711 suggests that while this hardware is very capable, there are many other configurations that deliver even higher frame rates in Roblox. This is likely due to the game's CPU-bound nature at lower resolutions, where CPUs with higher single-threaded performance or more aggressive boost clocks may pull ahead. The RTX 5070's role in the ranking is somewhat secondary, as the GPU's power is not fully utilized in this title.

CPU Role

The Intel Core i7-13700K is a 16-core, 24-thread processor based on the Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.40 GHz. It has 80 KB of L1 cache per core, 2 MB of L2 cache per core, and 30 MB of shared L3 cache. The CPU supports DDR4 and DDR5 memory in a dual-channel configuration, and it has a TDP of 125 W. Its benchmark scores include a Cinebench R23 multicore score of 30745 and a single-core score of 2116, as well as a Geekbench multicore score of 19429 and single-core score of 2529.

In Roblox, the CPU's role is critical because the game is known to be heavily CPU-bound, particularly in scenarios with many players or complex user-generated scripts. The measured FPS data supports this: at 1080p Low settings, the system achieves 537 FPS, which is likely near the game engine's limit. The CPU's single-threaded performance, as indicated by the 3DMark single-thread score of 1136 and Passmark single-thread score of 4333, is strong but not the absolute highest available. This is evident in the combo's rank of 789, which suggests that CPUs with higher single-threaded scores can push Roblox even further.

The CPU's 16 cores and 24 threads are more than sufficient for Roblox, which typically utilizes only a few threads. The high boost clock of 5.40 GHz helps with the game's single-threaded workload, but the data shows that the frame rates at 1080p are not limited by the GPU. The fact that the average FPS drops from 537 at 1080p Low to 358 at 1440p Low (a 33% decrease) indicates that the GPU is starting to become more involved, but the CPU is still keeping up. At 4K, the CPU has less of an impact on frame rates, as the GPU becomes the primary bottleneck, but the absolute numbers remain high.

The CPU's memory support for DDR4 and DDR5, along with its dual-channel memory bus, provides adequate bandwidth for Roblox's relatively modest memory requirements. The CPU's 30 MB of L3 cache also helps with game data access, though Roblox's performance is more dependent on clock speed and single-threaded efficiency than cache size. Overall, the Core i7-13700K is a strong match for the RTX 5070 in Roblox, but the data indicates that the CPU is the limiting factor at lower resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combination depend on the user's display resolution and refresh rate. At 1920x1080, all settings presets deliver over 350 FPS on average, which is far beyond the refresh rate of any mainstream monitor (typically 144 Hz or 240 Hz). For users with a 144 Hz monitor, Ultra settings at 350 FPS provide the best visual quality without any perceptible performance compromise. For users with a 240 Hz or higher refresh rate monitor, High settings at 432 FPS or even Medium settings at 489 FPS are recommended to maximize the frame rate while maintaining good visual fidelity.

At 2560x1440, the Ultra preset produces 234 FPS on average, which is sufficient for 144 Hz monitors. High settings at 288 FPS and Medium settings at 326 FPS are also excellent choices, with the latter providing the highest frame rates while still maintaining a playable experience. Low settings at 358 FPS are only recommended for competitive play where every frame counts, as the visual quality reduction is significant.

At 3840x2160, the Ultra preset produces 132 FPS on average, which is above 120 Hz but below 144 Hz. For users with a 4K 120 Hz display, Ultra settings are recommended for the best visual experience. For users with a 4K 144 Hz display, High settings at 163 FPS are a better choice to stay above the refresh rate, while Medium settings at 184 FPS provide an even higher frame rate with a slight reduction in visual quality. Low settings at 203 FPS are only recommended for users who prioritize maximum frame rates over visual fidelity.

In general, the Medium settings preset offers the best balance between visual quality and frame rate across all resolutions, as it consistently delivers high average FPS with the recorded minimum and maximum values showing good frame time consistency. The Ultra preset is recommended for users with 1080p or 1440p displays who want the best visuals, as the frame rates remain high enough to avoid any perceptible stutter. For 4K users, High or Medium settings are recommended over Ultra to ensure the frame rate stays above 144 FPS.
