# Roblox with AMD Ryzen 7 9700F + NVIDIA GeForce RTX 4080

This combination of an AMD Ryzen 7 9700F and NVIDIA GeForce RTX 4080 delivers exceptional performance in Roblox, ranking 250th out of 3,711 tested combos. The data shows a system capable of maintaining triple-digit frame rates even at 4K Ultra settings, with the RTX 4080's 16 GB of GDDR6X memory and the Ryzen 7 9700F's 8-core/16-thread Zen 5 architecture combining to produce some of the highest measured FPS values in the database.

Settings Recommendations

The measured FPS rows provide a clear picture of how each preset scales across resolutions. At 1080p, the Low preset delivers 643 FPS average, Medium achieves 585 FPS, High reaches 517 FPS, and Ultra drops to 420 FPS. The gap between Low and Ultra at 1080p is 223 FPS, representing a 34.7% performance reduction when moving from the lowest to highest quality settings. Given that even Ultra maintains 420 FPS, the highest preset is entirely viable for competitive or high-refresh-rate displays.

At 1440p, the pattern holds with Low at 429 FPS, Medium at 390 FPS, High at 345 FPS, and Ultra at 280 FPS. The delta between Low and Ultra shrinks to 149 FPS, a 34.7% drop that mirrors the 1080p scaling. Since all presets at 1440p remain above 280 FPS, users with 144Hz or 165Hz monitors can comfortably select Ultra without compromising refresh rate targets.

The 4K results reveal the first meaningful constraint. Ultra produces 158 FPS, High reaches 195 FPS, Medium hits 221 FPS, and Low tops out at 243 FPS. The spread between Low and Ultra at 4K is 85 FPS, a 35.0% reduction that aligns with the lower-resolution scaling. For 4K displays with 144Hz refresh rates, Ultra's 158 FPS average still exceeds the threshold, though Medium's 221 FPS provides additional headroom for demanding scenes. The measured minimum FPS at Medium 4K is 188 FPS, which suggests that Ultra's unmeasured minimum could potentially dip below 144 FPS in complex scenes, making Medium the safer recommendation for 4K high-refresh gaming.

The optimal preset depends on resolution targets. For 1080p and 1440p, Ultra delivers enough headroom above any realistic refresh rate to be the default choice. For 4K, Medium offers the best balance between visual quality and frame time consistency based on the measured minimum of 188 FPS.

GPU Role

The NVIDIA GeForce RTX 4080 serves as the primary rendering engine in this configuration, equipped with 16 GB of GDDR6X memory on a 256-bit bus delivering 716.8 GB/s of bandwidth. The GPU's Ada Lovelace architecture operates at a base clock of 2205 MHz with a boost clock of 2505 MHz, and the memory runs at 1400 MHz (22.4 Gbps effective). These specifications translate into a 3DMark Steel Nomad DX12 score of 6,567 and a PassMark G3D score of 34,457, placing the GPU in the 86th percentile among all tested graphics cards.

The RTX 4080's role in Roblox is substantial given the game's relatively modest rendering demands. The benchmark data shows that the GPU maintains frame rates that are limited more by CPU performance at lower resolutions and by GPU throughput at higher resolutions. At 1080p Low, the system reaches 643 FPS, which indicates that the GPU is not the bottleneck at these settings — the CPU's single-thread performance becomes the limiting factor. As resolution increases to 4K, the frame rate drops to 243 FPS at Low settings, demonstrating the GPU's increasing workload.

The GPU's 76 RT cores and 304 tensor cores provide substantial compute resources that Roblox likely does not fully utilize, given the game's art style. However, the raw rasterization throughput — 48.74 TFLOPS FP32, 280.6 GPixel/s pixel rate, and 761.5 GTexel/s texture rate — ensures that even Ultra settings at 4K remain well above 144 FPS. The GPU's nearest rival, the RTX 4080 SUPER, scores 54,209 on average benchmark score, a 0.1% delta from the RTX 4080's 54,247, indicating that this GPU sits at the very top of its performance tier.

CPU Role

The AMD Ryzen 7 9700F brings 8 cores and 16 threads based on the Zen 5 architecture, manufactured on TSMC's 4 nm process. With a base clock of 3.80 GHz and boost clock of 5.50 GHz, this processor achieves a PassMark single-thread score of 4,691 and a multithread score of 36,470. The 32 MB shared L3 cache and 1 MB L2 per core provide ample on-die storage for game data, while the dual-channel DDR5 memory interface delivers 89.6 GB/s of bandwidth.

In Roblox, CPU performance is critical due to the game's physics simulation and scripting workloads. The Ryzen 7 9700F's 94th percentile ranking among all CPUs reflects its strength in both single-threaded and multi-threaded tasks. The PassMark physics score of 2,122 and integer math score of 120,788 indicate strong computational throughput that benefits the game's simulation logic. The data compression score of 421,988 and floating-point math score of 77,955 further demonstrate the CPU's capability to handle varied workloads.

The CPU's nearest rivals provide context for its performance tier. The AMD Ryzen 9 7940HX scores 69,875 on average (0.2% higher), while the Intel Core i7-14700KF scores 70,163 (0.2% lower). The AMD Ryzen 9 7950X and Intel Core i7-14700K trail by 0.7% and 0.9% respectively. This clustering within a 1.1% band indicates that the Ryzen 7 9700F sits in a highly competitive performance segment, with no single rival offering a meaningful advantage.

At 1080p, the CPU's role becomes evident through the frame rate ceiling. The 643 FPS at Low settings suggests the CPU's single-thread performance cap is around that level for this workload, as the GPU could likely render more frames if the CPU allowed. The scaling from 420 FPS at Ultra 1080p to 280 FPS at Ultra 1440p and 158 FPS at Ultra 4K shows the GPU becoming progressively more dominant as resolution increases.

How This Combo Ranks

The combination of the Ryzen 7 9700F and RTX 4080 achieves a combo rank of 250 out of 3,711 tested configurations in Roblox, placing it in the top 6.7% of all tested systems. This ranking reflects the synergistic balance between the CPU's strong single-thread performance and the GPU's high rasterization throughput. The top 250 position indicates that while there are faster combinations, this system delivers excellent performance that exceeds the vast majority of tested hardware pairings.

The measured FPS values across all resolutions and settings support this ranking. At 1080p, the system achieves 517 FPS on High and 420 FPS on Ultra, which are exceptional numbers for any game. The 1440p results remain high, with Ultra at 280 FPS and High at 345 FPS. Even at 4K, the system maintains playable frame rates at all settings, from 243 FPS at Low to 158 FPS at Ultra.

The combo's ranking is particularly notable given that the RTX 4080 is marked as end-of-life production status, while the Ryzen 7 9700F is still active. This pairing represents a high-end configuration from the current hardware generation, and the benchmark data indicates that it handles Roblox with substantial headroom. The 250th rank out of 3,711 suggests that only a small fraction of tested systems — likely those with newer GPUs or higher-clocked CPUs — outperform this combination.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals the shifting bottleneck between CPU and GPU. At Low settings, the system drops from 643 FPS at 1080p to 429 FPS at 1440p (a 33.3% reduction) and then to 243 FPS at 4K (a 43.4% reduction from 1440p). This progressive decline indicates that the GPU becomes increasingly limiting as pixel count rises, while the CPU's contribution remains relatively constant.

At Ultra settings, the scaling follows a similar pattern: 420 FPS at 1080p drops to 280 FPS at 1440p (a 33.3% reduction) and further to 158 FPS at 4K (a 43.6% reduction from 1440p). The consistent percentage drops between resolutions suggest that the rendering workload scales predictably with pixel count, and the RTX 4080's 16 GB VRAM capacity prevents any memory-related performance cliffs.

The ratio between Low and Ultra FPS remains remarkably stable across resolutions: 643/420 = 1.53 at 1080p, 429/280 = 1.53 at 1440p, and 243/158 = 1.54 at 4K. This consistency indicates that the performance difference between settings is independent of resolution, and the GPU's shading units and memory bandwidth scale proportionally with the workload. The limiting component at 1080p appears to be the CPU, as the GPU has significant headroom to render more frames if the CPU could provide them. At 4K, the GPU becomes the primary constraint, though it still delivers well above 144 FPS at Ultra.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 643 FPS, Medium achieves 585 FPS with a minimum of 497 FPS and maximum of 673 FPS, High reaches 517 FPS, and Ultra yields 420 FPS. The Medium preset's measured range of 497-673 FPS indicates substantial frame time variability even at these high rates, though the average remains far above any display refresh rate.

Moving to 2560x1440, the frame rates remain exceptionally high. Low settings average 429 FPS, Medium produces 390 FPS with a minimum of 332 FPS and maximum of 449 FPS, High reaches 345 FPS, and Ultra hits 280 FPS. The Medium preset at 1440p shows a 117 FPS range between minimum and maximum, which is narrower than the 176 FPS range at 1080p, suggesting more consistent frame pacing at higher resolutions.

At 3840x2160, the system still maintains impressive performance. Low settings average 243 FPS, Medium achieves 221 FPS with a minimum of 188 FPS and maximum of 254 FPS, High reaches 195 FPS, and Ultra produces 158 FPS. The Medium preset's 66 FPS range at 4K is the tightest of any resolution, indicating that the GPU's workload becomes more consistent at higher pixel counts. The 4K results show that even the lowest measured minimum (188 FPS at Medium) remains well above common 144Hz refresh rates, providing a smooth experience across all settings.

The progression across resolutions shows a clear pattern: each step from 1080p to 1440p to 4K reduces frame rates by roughly one-third, while the relative ordering between settings remains consistent. The Medium preset consistently falls between Low and High, with the measured minimum and maximum values providing useful bounds for frame time variability.
