Roblox

The Intel Core i5-11400F paired with the AMD Radeon RX 9070 ranks 1122 out of 3711 tested combos in Roblox, placing it in the 30th percentile of all system pairings evaluated for this game. This is a strong result, driven largely by the GPU’s ability to push very high frame rates even at 4K, while the six-core, twelve-thread CPU provides enough single-thread headroom to avoid becoming the primary bottleneck. The data shows that this combo is positioned for high-refresh-rate play at 1440p and for smooth 4K experiences, with the CPU’s 71st percentile ranking among all CPUs and the GPU’s 69th percentile among all GPUs indicating a balanced pairing where neither component dramatically underperforms the other.

How This Combo Ranks

At position 1122 out of 3711 combos, this system sits comfortably in the top third of all tested pairings for Roblox. The combo’s rank reflects a meaningful advantage over the median setup, but it is not an extreme outlier at the very top of the charts. The CPU’s average benchmark score of 17177 places it just 0.3% above the AMD EPYC 7H12 (17120) and 0.6% above the Intel Core Ultra 7 164U (17074), while trailing the Intel Core i5-12450H by 0.4% (17239) and the AMD Ryzen 3 PRO 8300G by 0.6% (17278). These small deltas indicate that in raw compute terms, the i5-11400F is effectively tied with a cluster of very different processors, from server-class EPYC parts to mobile laptop chips. What matters for Roblox is that the CPU’s single-thread performance — a 3DMark single-thread score of 868 and a Cinebench R23 single-core score of 2024 — is well above what the game typically demands, so even older-generation architecture does not hold back the RX 9070.

The GPU’s average benchmark score of 23877 positions it 0.6% above the NVIDIA GeForce GTX TITAN Z (23736) and 1.1% above the NVIDIA GeForce RTX 3080 Mobile (23628), while sitting 0.8% below the AMD Radeon RX 6800S (24063) and 1.2% below the NVIDIA GeForce RTX 2080 SUPER (24170). In the context of Roblox, these rival deltas are less relevant than the absolute FPS numbers, because the game is not particularly demanding on graphics hardware. The combo’s rank of 1122 suggests that many other pairings — likely those with newer, higher-clocked CPUs or more powerful GPUs — achieve even higher frame rates, but the margin between this combo and those above it is often small in actual gameplay. For a user targeting 144Hz or 165Hz displays, this rank indicates the system will consistently exceed those refresh rates at 1440p and come close at 4K with adjusted settings.

GPU Role

The AMD Radeon RX 9070 is the dominant component in this pairing for Roblox, and its specifications explain why. The GPU features 16 GB of GDDR6 memory on a 256-bit bus, providing 644.6 GB/s of memory bandwidth. For a game like Roblox, which often relies on simple textures and modest geometry, 16 GB is far more than necessary; the practical benefit is that memory capacity will never be a constraint, even with high-resolution textures or many concurrent players in a server. The memory clock runs at 2518 MHz, translating to 20.1 Gbps effective, which is ample for the data throughput Roblox generates. The GPU’s base clock is 1330 MHz, with a boost clock of 2520 MHz and a game clock of 2070 MHz, meaning that under sustained load in Roblox, the card will operate near its game clock rather than its maximum boost, but the high frame rates measured indicate that even this sustained level is more than enough.

The RX 9070’s 3584 shading units, 224 texture mapping units, and 128 raster output units are all high counts for a modern graphics card, and they directly contribute to the measured FPS. The pixel rate of 322.6 GPixel/s and texture rate of 564.5 GTexel/s show that the GPU can fill frames and apply textures at rates far exceeding what Roblox requires. The FP32 performance of 36.13 TFLOPS is substantial, though Roblox’s rendering pipeline does not stress compute to that degree. The GPU also has 56 ray tracing cores, but Roblox does not use ray tracing in a way that would meaningfully impact these results, so this hardware remains mostly idle. The power draw of 220 W and the suggested 550 W PSU indicate that this is a mainstream-power GPU, not an extreme flagship, which aligns with its performance tier — it outperforms older high-end cards like the RTX 2080 SUPER by a small margin in synthetic benchmarks but does not reach the heights of current top-tier GPUs.

In Roblox specifically, the GPU’s role is to render simple scenes at extremely high frame rates. The measured data shows that even at 4K Ultra, the average FPS is 117, which is far above the 60 FPS target most games aim for. This suggests that the RX 9070 is overkill for Roblox in most scenarios, but that overkill translates directly into headroom for higher refresh rates or for keeping FPS stable in busy servers with many players and complex user-generated content. The 16 GB VRAM also ensures that any future updates to Roblox that add more detailed assets will not force a reduction in texture quality.

Resolution Scaling

The measured FPS data reveals a clear pattern of scaling from 1080p to 4K, with the GPU becoming more of a limiting factor at higher resolutions. At 1080p with Low settings, the combo averages 474 FPS; at Medium, 431 FPS; at High, 381 FPS; and at Ultra, 309 FPS. Moving to 1440p, those numbers drop to 316 FPS for Low, 288 FPS for Medium, 254 FPS for High, and 206 FPS for Ultra. At 4K, the averages fall further to 179 FPS for Low, 163 FPS for Medium, 144 FPS for High, and 117 FPS for Ultra. The percentage drops from 1080p to 4K are substantial: Low settings lose about 62% of the frame rate (474 to 179 FPS), Medium loses 62% (431 to 163 FPS), High loses 62% (381 to 144 FPS), and Ultra loses 62% (309 to 117 FPS). This consistent ~62% reduction across all settings strongly indicates that the GPU is the scaling bottleneck as resolution increases, because the CPU’s workload does not change much with resolution — it is the GPU that must render more pixels.

The fact that even at 4K Ultra the average FPS remains above 100 shows that the GPU is not severely stressed by Roblox. The scaling pattern also reveals that at 1080p, the CPU may be starting to limit performance. Consider the jump from Low to Ultra at 1080p: FPS drops from 474 to 309, a 35% reduction. At 4K, the same settings change results in a drop from 179 to 117, also a 35% reduction. This proportionality suggests that the CPU is not the primary limiter even at 1080p, because if it were, the FPS would remain similar across resolutions at a given setting. Instead, the GPU handles the entire load scaling. However, the absolute FPS values at 1080p — over 300 FPS even at Ultra — are so high that the CPU’s single-thread performance (Cinebench R23 single-core score of 2024) is sufficient to feed the GPU without creating a bottleneck. If the CPU were weaker, we would expect to see a plateau in FPS at 1080p, but the data shows continuous scaling from Low to Ultra, which argues against that.

The 4K Medium reading includes a minimum FPS of 138 and a maximum of 187, while the 1440p Medium shows a minimum of 245 and maximum of 331, and the 1080p Medium shows a minimum of 367 and maximum of 496. These ranges indicate that frame times are relatively consistent, with no severe stuttering or drops that would suggest a CPU limitation. The spread between min and max is roughly 25-30% of the average, which is typical for a game like Roblox where server-side events and player counts can cause occasional frame dips. Overall, the resolution scaling data tells a clear story: this combo is GPU-bound at 4K, CPU-bound at 1080p only in the sense that the CPU cannot push beyond the 474 FPS ceiling, and well balanced at 1440p where both components have headroom.

Settings Recommendations

Based on the measured FPS values, the best experience for most users will be Medium settings at 1440p, where the combo averages 288 FPS with a minimum of 245 FPS. That minimum is still well above 144Hz, so even in busy scenes the frame rate will not drop below a high-refresh-rate monitor’s capability. At 1080p, Medium settings deliver 431 FPS on average with a minimum of 367 FPS, which is excessive for any current display but useful for competitive play where every frame matters, or for users with 240Hz or 360Hz monitors. The Ultra preset at 1440p yields 206 FPS on average, which is still excellent, but the jump from Medium to Ultra costs 82 FPS (288 to 206) while the visual difference in Roblox is often negligible given the game’s art style. Therefore, Medium represents the sweet spot: it retains high visual quality while maximizing frame rate headroom.

At 4K, the recommendation depends on the display’s refresh rate. For a 144Hz 4K monitor, Medium settings (163 FPS average, 138 FPS minimum) will keep the display saturated, while High settings (144 FPS average) may occasionally dip below 144 FPS in heavy moments. Ultra at 4K (117 FPS average) is playable on a 120Hz display but will not fully utilize a 144Hz panel. Low settings at 4K (179 FPS) offer the highest frame rates but sacrifice visual fidelity unnecessarily, since the GPU can handle Medium without issue. The data suggests that for 4K users, Medium is the optimal preset because it provides a 163 FPS average, which is above 144Hz, and the minimum of 138 FPS is acceptable even if it briefly drops below the refresh rate. For 1080p users with very high refresh rate displays (240Hz or more), Low settings at 474 FPS will maximize frame rate, but Medium at 431 FPS is close enough that the visual improvements justify the small FPS loss.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. Low settings produce an average of 474 FPS, Medium produces 431 FPS with a minimum of 367 and a maximum of 496, High produces 381 FPS, and Ultra produces 309 FPS. These numbers indicate that at 1080p, the system is never constrained by the GPU; even Ultra settings exceed 300 FPS, which is far beyond what most monitors can display. The difference between Low and Ultra is 165 FPS (474 to 309), a 35% reduction, which shows that the settings do have an impact, but the absolute performance is so high that users can choose any preset without worrying about playability. The minimum FPS recorded at 1080p Medium is 367, which is still higher than the average FPS at 4K Medium, highlighting how resolution dramatically changes the performance envelope.

At 2560x1440, the frame rates remain very high but begin to show the GPU’s workload increasing. Low settings average 316 FPS, Medium averages 288 FPS with a minimum of 245 and a maximum of 331, High averages 254 FPS, and Ultra averages 206 FPS. The drop from Low to Ultra is 110 FPS (316 to 206), a 35% reduction, consistent with the 1080p pattern. The 1440p Medium minimum of 245 FPS is particularly notable because it means that even in the most demanding moments, the frame rate stays above 240Hz, making this an ideal resolution for high-refresh-rate gaming. High settings at 1440p (254 FPS average) are also excellent, and the difference between High and Ultra (48 FPS) is larger than the difference between Medium and High (34 FPS), suggesting that Ultra imposes a disproportionately heavy load for the visual gain.

At 3840x2160, the GPU is fully utilized, but the results are still impressive. Low settings average 179 FPS, Medium averages 163 FPS with a minimum of 138 and a maximum of 187, High averages 144 FPS, and Ultra averages 117 FPS. The drop from Low to Ultra is 62 FPS (179 to 117), a 35% reduction, again matching the pattern. The 4K Medium minimum of 138 FPS is the only measured minimum below 144 FPS across all settings and resolutions, which means that 4K Medium is the first configuration where the system might occasionally struggle to maintain a 144Hz refresh rate. High settings at 4K (144 FPS average) sit right at the 144Hz threshold, so users with 144Hz displays should prefer Medium for a safety margin. Ultra at 4K (117 FPS) is fine for 120Hz displays but not for 144Hz. Low at 4K (179 FPS) is playable but unnecessary, as the visual quality loss is not worth the 16 FPS gain over Medium.

FAQ

Q: Is this combo capable of 144Hz gaming at 4K in Roblox?

A: Yes, but with a caveat. The measured data shows that at 4K Medium, the average FPS is 163 with a minimum of 138 FPS. This means the average exceeds 144Hz, but the minimum falls slightly below, so there may be brief dips below the refresh rate. At 4K High, the average is exactly 144 FPS, which means it will often hover at or below 144Hz. For a consistent 144Hz experience, 4K Medium is the best choice.

Q: How does this combo’s CPU compare to its nearest rivals?

A: The Intel Core i5-11400F has an average benchmark score of 17177, which is 0.3% higher than the AMD EPYC 7H12 (17120) and 0.6% higher than the Intel Core Ultra 7 164U (17074). It is 0.4% lower than the Intel Core i5-12450H (17239) and 0.6% lower than the AMD Ryzen 3 PRO 8300G (17278). These differences are minor, meaning the CPU performs on par with a range of server, mobile, and desktop processors.

Q: What is the best resolution for this combo to maximize FPS?

A: Based on the measured data, 1080p offers the highest frame rates, with Low settings averaging 474 FPS and Medium averaging 431 FPS. However, 1440p Medium still delivers 288 FPS on average with a minimum of 245 FPS, which is more than sufficient for any high-refresh-rate monitor. The choice depends on whether the user prioritizes maximum FPS (1080p) or higher resolution with still-excellent FPS (1440p).

Q: Does the GPU’s 16 GB VRAM matter for Roblox?

A: In practice, no. Roblox’s visual complexity is low, and the game does not require large amounts of video memory. The measured FPS at 4K Ultra (117 FPS) shows that the GPU’s memory capacity is not a limiting factor. The 16 GB is more than enough for current Roblox content and provides headroom for future updates, but it does not directly contribute to higher FPS in this game.

Q: How does the RX 9070 compare to its nearest GPU rivals?

A: The RX 9070 has an average benchmark score of 23877, which is 0.6% higher than the NVIDIA GeForce GTX TITAN Z (23736) and 1.1% higher than the NVIDIA GeForce RTX 3080 Mobile (23628). It is 0.8% lower than the AMD Radeon RX 6800S (24063) and 1.2% lower than the NVIDIA GeForce RTX 2080 SUPER (24170). These deltas indicate that the RX 9070 performs very close to those GPUs in synthetic benchmarks, though in Roblox the differences are unlikely to be noticeable given the high absolute FPS.

Q: Will the CPU bottleneck the GPU at any resolution?

A: The data suggests that the CPU is not a significant bottleneck at 1440p or 4K, where the GPU is clearly the limiting factor due to the ~62% FPS drop from 1080p to 4K. At 1080p, the CPU may cap performance, as the maximum measured FPS is 474 at Low settings, but this is so high that it does not affect practical use. The CPU’s single-thread performance (Cinebench R23 score of 2024) is adequate to feed the GPU even at high frame rates.
