Roblox

Roblox is not a typical graphics showcase, but the AMD Ryzen 7 9700F and NVIDIA GeForce RTX 3080 Ti combination delivers a staggering range of frame rates, from a floor of 123 FPS at 4K Ultra to a ceiling of 500 FPS at 1080p Low. The data available for this pairing is measured, not estimated, and it reveals a system that is overwhelmingly capable of saturating high-refresh-rate displays at any resolution, with the primary bottlenecks shifting from the GPU at 4K to the CPU at 1080p.

Resolution Scaling

The measured FPS data shows a clear and predictable trend: as resolution increases, average frame rates drop, but the margin of that drop is heavily dependent on the graphics preset. The scaling from 1080p to 1440p to 4K is not uniform, indicating a shift in the limiting component.

At the Low preset, the frame rate drops from 500 FPS at 1080p to 334 FPS at 1440p, a reduction of 166 FPS (about 33%). Moving from 1440p to 4K Low brings the average down to 189 FPS, another 145 FPS drop (about 43%). This steep decline suggests that even at Low settings, the GPU is becoming more of a factor at higher resolutions, though the absolute numbers remain exceptionally high.

The High preset shows a similar pattern but with a less dramatic initial drop. From 1080p High (402 FPS) to 1440p High (268 FPS), the loss is 134 FPS (33%). However, the 1440p to 4K transition is steeper, falling from 268 FPS to 152 FPS, a 116 FPS loss (43%). This indicates that the 4K resolution is starting to put real load on the RTX 3080 Ti, which has 12 GB of GDDR6X memory and a 384-bit memory bus.

The Ultra preset demonstrates the most significant scaling penalty. The system delivers 326 FPS at 1080p Ultra, which is still a phenomenal result. Dropping to 1440p Ultra yields 218 FPS, a 108 FPS loss (33%). At 4K Ultra, the average plummets to 123 FPS, a further 95 FPS loss (44%). This 4K Ultra figure is the lowest measured in the entire data set, suggesting that this is the first point where the GPU’s pixel throughput and memory bandwidth are being taxed to a degree that noticeably limits performance.

The scaling pattern across all presets is remarkably consistent in percentage terms, hovering around 33% for the 1080p to 1440p step and 43-44% for the 1440p to 4K step. This consistency implies that the game’s engine scales its workload predictably with pixel count. At 1080p, the CPU is likely the primary limiter, as reducing the resolution from 1440p to 1080p does not yield a proportional increase in frame rate for the High preset (268 to 402 FPS is a 50% gain, not the 78% pixel count reduction). This suggests the Ryzen 7 9700F, with its 8 cores and 16 threads, is a capable partner but still a ceiling at lower resolutions. At 4K, the GPU becomes the dominant factor, and the RTX 3080 Ti’s 34.10 TFLOPS of FP32 performance is what keeps the frame rates in the triple digits.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the clear driver of 4K performance in this pairing. Its specifications are substantial: a GA102 chip on the Ampere architecture, built on an 8 nm process at Samsung. The GPU boasts 10240 shading units, 320 TMUs, and 112 ROPs, which contribute to its 186.5 GPixel/s pixel rate and 532.8 GTexel/s texture rate. These figures explain why the card can push Roblox to 152 FPS at 4K High.

The GPU’s 12 GB of GDDR6X memory on a 384-bit bus provides 912.4 GB/s of bandwidth. This high bandwidth is critical for maintaining performance at 4K, where texture data and frame buffers are large. The measured data shows that the 4K Ultra preset (123 FPS) is 19% slower than 4K High (152 FPS), suggesting that the Ultra preset introduces effects or settings that place a heavy load on the GPU's compute and memory subsystems. The 34.10 TFLOPS of FP32 compute is ample for a game like Roblox, which is not known for photorealistic workloads, but the scaling to 4K Ultra shows that even this powerful card has limits.

The GPU’s boost clock is listed at 1665 MHz, with a base clock of 1365 MHz. The measured frame rates suggest that the card is not thermally or power constrained in this title, as it consistently delivers high performance across all settings. The card’s 350 W TDP is a consideration for system builders, but it is an expected figure for a high-end Ampere part. The GPU's production status is end-of-life, yet its benchmark scores place it in the 83rd percentile, showing that it remains a capable performer. The nearest rival data shows it is only 2% ahead of the RTX 5070 in average score, indicating that newer generation cards have caught up, but the 3080 Ti still holds its own in this specific game.

How This Combo Ranks

The AMD Ryzen 7 9700F and RTX 3080 Ti combination ranks 766th out of 3010 tested combos for Roblox. This places it in the top 25.4% of all pairings in the database. This is a strong result, but not a top-tier one, which makes sense given the nature of the game and the hardware.

The rank suggests that while this combo is excellent, there are many other systems that can deliver similar or better performance in Roblox. The game is inherently CPU-bound at lower resolutions, and the Ryzen 7 9700F’s single-thread performance, while strong, is not the absolute best. The CPU’s PassMark single-thread score is 4691, and its average benchmark score of 69996 is competitive with the Intel Core i7-14700KF. However, the ranking implies that other CPUs with higher single-core performance might pair better for the absolute highest frame rates at 1080p.

The GPU’s 83rd percentile ranking among all GPUs is a positive sign for the overall combo rank. The RTX 3080 Ti is a powerful card, and when coupled with a strong CPU, it should perform well. The fact that this combo is in the 766th spot indicates that the bottleneck at 1080p is more likely the CPU, as many other combos with similar GPUs but faster CPUs (like the 14700KF or Ryzen 9 7950X) would likely rank higher in a CPU-bound scenario. At 4K, the GPU takes over, and this combo’s rank would likely improve relative to others with weaker GPUs.

Measured FPS Breakdown

The dataset provides exact average FPS figures for four settings presets (Low, Medium, High, Ultra) across three resolutions. Here is the complete breakdown:

At 1920x1080:

• Low: 500 FPS average.
• Medium: 455 FPS average, with a minimum of 387 FPS and a maximum of 523 FPS.
• High: 402 FPS average.
• Ultra: 326 FPS average.

At 2560x1440:

• Low: 334 FPS average.
• Medium: 304 FPS average, with a minimum of 258 FPS and a maximum of 349 FPS.
• High: 268 FPS average.
• Ultra: 218 FPS average.

At 3840x2160:

• Low: 189 FPS average.
• Medium: 172 FPS average, with a minimum of 146 FPS and a maximum of 197 FPS.
• High: 152 FPS average.
• Ultra: 123 FPS average.

The data shows a consistent hierarchy: Low is always the fastest, followed by Medium, then High, and finally Ultra. The difference between Low and Ultra is substantial at every resolution, but the gap narrows as resolution increases. At 1080p, the gap is 174 FPS (500 vs 326). At 1440p, it is 116 FPS (334 vs 218). At 4K, it is 66 FPS (189 vs 123). This indicates that the CPU is a major factor in the frame rate differences at lower resolutions, while the GPU’s workload scaling with resolution reduces the relative impact of the settings preset. The only min/max data provided is for the Medium preset, showing that even the minimum FPS at 1080p Medium (387 FPS) is higher than the maximum FPS at 4K Medium (197 FPS).

Settings Recommendations

Given the measured data, the optimal settings preset is dependent on the user's display and preference for maximum frame rate versus visual fidelity.

For 1080p and 1440p users with high-refresh-rate monitors (240Hz or higher), the Low preset is the only choice if chasing the absolute maximum frame rate. At 1080p Low, the system delivers 500 FPS, and at 1440p Low, it provides 334 FPS. These are the highest numbers available in the dataset. However, the visual difference between Low and Medium is often significant, and the Medium preset still delivers 455 FPS at 1080p and 304 FPS at 1440p. These are still exceptionally high frame rates that would exceed the refresh rate of most monitors. Therefore, for most users at these resolutions, the Medium preset offers the best balance of visual quality and performance, as it maintains an average above 300 FPS at 1440p and above 450 FPS at 1080p.

For 4K users, the choice is more nuanced. The Ultra preset at 4K yields 123 FPS, which is playable but may not be enough for 144Hz monitors. The High preset at 4K yields 152 FPS, which is a 24% improvement over Ultra and is a better option for 144Hz displays. The Medium preset at 4K offers 172 FPS, which is a 40% improvement over Ultra. Given that Roblox is a sandbox game where gameplay clarity often matters more than high-end graphics effects, the Medium preset at 4K is a strong recommendation, as it provides a high average FPS of 172 with a minimum of 146 FPS, ensuring a smooth experience without dipping below 144 FPS. The Ultra preset, while visually superior, is best reserved for users with 120Hz displays or those who prioritize image quality over raw frame rate. The data clearly shows that the RTX 3080 Ti is not fully utilized until 4K Ultra, making the lower presets at 4K somewhat CPU-limited, but the Medium preset offers the most headroom for consistent high performance.
