Roblox

Resolution Scaling

Roblox is not a typical GPU stress test, and the measured frame rates for the AMD Ryzen 7 9700F paired with the NVIDIA GeForce RTX 3080 demonstrate this clearly. At 1080p with Low settings, the combo produces an average of 482 FPS. Moving to 1440p Low drops that to 321 FPS, a reduction of roughly 33%. At 4K Low, the average falls to 182 FPS, which is another 43% drop from the 1440p figure. This scaling pattern is steep, but the absolute numbers remain extremely high.

The scaling behavior changes notably when the settings are increased. At Ultra settings, the 1080p average is 314 FPS, 1440p is 210 FPS, and 4K is 119 FPS. The percentage drop from 1080p to 1440p at Ultra is about 33%, and from 1440p to 4K it is roughly 43%. This is nearly identical to the scaling seen at Low settings. In many modern titles, the gap between 1440p and 4K widens more dramatically as the GPU becomes the bottleneck. Here, the consistent scaling suggests that the game’s engine, which is heavily CPU-bound at high frame rates, is still feeding the GPU enough data to keep the scaling profile stable even at 4K.

The data indicates a system that is never truly struggling. Even at the most demanding tested configuration, 4K Ultra, the average FPS is 119. This is well above the refresh rate of standard 60 Hz displays and even competitive with many 120 Hz panels. The fact that the 4K Ultra average is still over 100 FPS implies that the limiting factor is not the raw pixel-pushing power of the RTX 3080, but rather the game's ability to utilize that power. Roblox’s rendering engine has inherent overhead, and the performance ceiling here is likely defined by the CPU’s single-threaded speed and the game’s draw call limitations. The 4K Low result of 182 FPS versus the 4K Ultra result of 119 FPS shows that settings do matter, but the floor is remarkably high. The data suggests that this combination is powerful enough to run Roblox at maximum refresh rates on high-refresh monitors at 1440p, and it remains entirely playable at 4K with high refresh rates on most displays.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end Ampere architecture card, built on Samsung’s 8 nm process. It features 8704 shading units, 272 texture mapping units, and 96 raster output units. The card has 68 RT cores and 272 tensor cores, and its compute power is rated at 29.77 TFLOPS for FP32 operations. The memory subsystem is a 10 GB GDDR6X pool on a 320-bit bus, delivering 760.3 GB/s of bandwidth. The boost clock is rated at 1710 MHz.

Given this hardware, the GPU’s role in Roblox is almost secondary to the CPU. The measured FPS data shows that the GPU is rarely the bottleneck, even at 4K. The difference between 1080p Low at 482 FPS and 4K Low at 182 FPS is 300 FPS, which is a massive absolute drop, but the 4K number is still high enough to suggest the GPU is not saturated. In a traditional GPU-bound scenario, we would expect the 4K performance to collapse to a fraction of the 1080p number, often below 100 FPS for a game like this on a mid-range card. Here, the RTX 3080’s immense bandwidth and pixel throughput allow it to handle the increased resolution without breaking a sweat.

The VRAM capacity of 10 GB is another factor. Roblox is not a texture-heavy game, and it is unlikely to exceed 10 GB of VRAM at any settings, even at 4K. The data confirms this, as the performance does not show signs of VRAM capacity stutter or severe drops. The memory bandwidth of 760.3 GB/s is more than sufficient for the game's demands. The GPU’s percentile ranking against all GPUs is 68, and its average benchmark score is 23172. Its nearest rivals include the NVIDIA P106-100 and the AMD Radeon RX 6600M, which are significantly slower cards, indicating that the RTX 3080 sits in a comfortable position of superiority for this workload. In the context of Roblox, the RTX 3080 is providing headroom that allows the CPU to be the primary performance driver. The data shows that the GPU is effectively waiting for data from the processor, rather than being the limiting factor.

CPU Role

The AMD Ryzen 7 9700F is an 8-core, 16-thread processor based on the Zen 5 architecture, codenamed Granite Ridge. It is built on TSMC’s 4 nm process and has a base clock of 3.80 GHz with a boost clock of 5.50 GHz. The CPU has 8 MB of L2 cache (1 MB per core) and 32 MB of shared L3 cache. Its memory bandwidth is rated at 89.6 GB/s with dual-channel DDR5 support. The CPU’s benchmark scores show a strong single-threaded performance, with a Passmark single-thread score of 4691, and a multithread score of 36470.

Roblox is notoriously CPU-bound, and the data here strongly supports that characterization. The scaling from 1080p to 4K is almost linear in terms of the settings, but the frame rates are so high that the CPU must be the primary limiter. At 1080p Low, the average FPS is 482, which is an astronomically high number. This is only possible if the CPU can process the game’s logic and issue draw calls at a rate exceeding 480 per second. The Ryzen 7 9700F’s high boost clock of 5.50 GHz and strong IPC from the Zen 5 architecture are the key enablers here.

The CPU’s percentile ranking against all CPUs is 94, putting it in the top 6% of all processors. Its average benchmark score is 69996, and its nearest rivals include the AMD Ryzen 9 7940HX, the Intel Core i7-14700KF, and the AMD Ryzen 9 7950X. The DeltaPct values are all within a tight range, from 0.9% faster than the i7-14700K to 0.7% slower than the Ryzen 9 7950X. This places the 9700F in the absolute top tier of gaming CPUs. The multithreaded score of 36470 is also high, but for Roblox, the single-threaded performance is far more relevant. The difference between 1080p Low at 482 FPS and 4K Low at 182 FPS is 300 FPS, which is a massive absolute drop, but the 4K number is still high enough to suggest the GPU is not saturated.

The CPU’s 8 cores and 16 threads are more than enough for Roblox, which typically uses only a few threads. The high clock speed is the main driver of the high minimum frame rates, as the game’s main thread must be serviced quickly. The measured data shows that the CPU has enough headroom to push the RTX 3080 to its limits, but the game's engine caps the overall throughput. In essence, the Ryzen 7 9700F is not just a capable partner for the RTX 3080 in this game; it is the reason why the frame rates are as high as they are.

How This Combo Ranks

The combination of the AMD Ryzen 7 9700F and the NVIDIA GeForce RTX 3080 ranks 822 out of 3010 tested combos in Roblox, placing it in the top 27% of all system configurations. While a rank of 822 might not sound like a top-tier placement, it is important to consider the context. The top 821 combos likely include more recent, top-end graphics cards like the RTX 4090 or the RTX 5080, and possibly CPUs with even higher single-threaded performance. Given that the RTX 3080 is an end-of-life product from 2020, this rank confirms the CPU’s strength.

The RTX 3080’s percentile ranking against all GPUs is 68, which is solid but not outstanding. However, the CPU’s percentile ranking is 94, which is excellent. This suggests that the CPU is carrying the combo’s performance in Roblox. The data shows that the CPU is the primary driver of the high frame rates, and the GPU is merely following along. The fact that this combo reaches a rank of 822, despite the GPU being several generations old, is a direct result of the Ryzen 7 9700F’s powerful single-threaded performance.

Comparatively, the CPU’s nearest rivals, such as the Ryzen 9 7950X and the Core i7-14700KF, are all within 1% of its average benchmark score. This means that swapping the 9700F for any of those CPUs would likely result in nearly identical Roblox performance, as the game is not sensitive to the small differences in multi-core scores. The GPU’s nearest rivals, like the RX 6600M, are significantly slower, but they are also in a different class. The RTX 3080’s position in the 68th percentile is adequate, and when paired with a top-tier CPU, it is more than enough to achieve high refresh rates in Roblox. The ranking of 822 out of 3010 is a strong result for a hardware pairing that is not the newest on the market, and it indicates that the system is well-balanced for this specific game, with the CPU providing the necessary muscle to avoid bottlenecking the GPU.

Settings Recommendations

The measured FPS data provides a clear picture of how each settings preset affects performance. For users with a 1080p monitor, the Low preset yields an average of 482 FPS, Medium yields 438 FPS, High yields 387 FPS, and Ultra drops to 314 FPS. All of these are far above the refresh rate of any standard 1080p monitor, which typically tops out at 240 Hz or 360 Hz for the most extreme esports panels. Therefore, at 1080p, the Ultra preset is the recommended choice, as it provides the best visual quality while still delivering an average of 314 FPS. This is more than enough for even the fastest competitive displays.

At 1440p, the situation is similar. The Low preset averages 321 FPS, Medium 293 FPS, High 259 FPS, and Ultra 210 FPS. A 1440p monitor with a 240 Hz refresh rate is a common high-end choice, and the Ultra preset’s 210 FPS average is just below that threshold. However, the High preset at 259 FPS is well above 240 Hz and offers a significant visual improvement over Low. For users who prioritize maximum frame rates, Low is still an option, but the High preset strikes a better balance between visual fidelity and performance. The data suggests that High is the sweet spot for 1440p, as it comfortably exceeds 240 Hz while providing a more detailed image.

At 4K, the recommendations shift. The Low preset averages 182 FPS, Medium 165 FPS, High 146 FPS, and Ultra 119 FPS. For a 4K 120 Hz display, the Medium preset’s 165 FPS is more than sufficient, and the High preset’s 146 FPS is still above 120 Hz. The Ultra preset’s 119 FPS is just below a 120 Hz refresh rate, so it may be suitable for a 60 Hz display but would not fully utilize a 120 Hz panel. Given that 4K displays are typically larger and viewed from a distance, the visual difference between Medium and Ultra is more noticeable. The data indicates that the High preset is the best choice for 4K, as it provides a significant quality boost over Medium while still maintaining an average FPS that is high enough for a smooth experience on a 120 Hz monitor. The Medium preset is a fallback for users who want to ensure a rock-solid 144 Hz, but High is the recommended balance.

Measured FPS Breakdown

The following data was measured for the AMD Ryzen 7 9700F and NVIDIA GeForce RTX 3080 combination in Roblox.

At 1920x1080, the Low preset delivers an average of 482 FPS. The Medium preset averages 438 FPS, with a minimum of 373 FPS and a maximum of 504 FPS. The High preset averages 387 FPS. The Ultra preset averages 314 FPS.

At 2560x1440, the Low preset delivers an average of 321 FPS. The Medium preset averages 293 FPS, with a minimum of 249 FPS and a maximum of 336 FPS. The High preset averages 259 FPS. The Ultra preset averages 210 FPS.

The minimum FPS data is only available for the Medium preset at each resolution, but it shows a consistent pattern. At 1080p Medium, the minimum is 373 FPS, which is only 65 FPS below the average. At 1440p Medium, the minimum is 249 FPS, which is 44 FPS below the average. At 4K Medium, the minimum is 141 FPS, which is 24 FPS below the average. This indicates that the frame pacing is consistent, with no severe stutters or drops. The difference between the average and minimum FPS narrows as resolution increases, which suggests that the GPU is becoming more of a factor at higher resolutions, but the overall experience remains smooth. The maximum FPS values are also consistent, with the 1080p Medium hitting 504 FPS, 1440p Medium hitting 336 FPS, and 4K Medium hitting 190 FPS. These numbers reinforce the conclusion that this hardware combination provides an exceptionally high-performance experience in Roblox, with the CPU driving the frame rates and the GPU providing ample headroom.
