GPU Role

The AMD Radeon RX 9070 is built on the RDNA 4.0 architecture, with a chip design identified as Navi 48 and fabricated on a 4 nm process. The GPU is equipped with 16 GB of GDDR6 memory on a 256-bit bus, providing a memory bandwidth of 644.6 GB/s. The memory clock speed is listed at 2518 MHz, which translates to 20.1 Gbps effective. These specifications position the GPU to handle high-resolution textures and complex rendering tasks without significant memory capacity constraints.

The clock speeds of the RX 9070 are a key factor in its performance. The base clock is 1330 MHz, the game clock is rated at 2070 MHz, and the boost clock reaches 2520 MHz. The difference between the base and boost clocks indicates a substantial dynamic range, allowing the GPU to scale performance across different workloads. In Roblox, the data suggests that the GPU is operating within its intended performance envelope, as frame rates scale predictably with resolution and settings.

The GPU's compute capabilities include 3,584 shading units, 224 texture mapping units, and 128 render output units. The texture rate is 564.5 GTexel/s, and the pixel rate is 322.6 GPixel/s, with FP32 performance rated at 36.13 TFLOPS. These metrics provide a theoretical ceiling for how much geometry and texture data the GPU can process per second, which matters for Roblox's sometimes-heavy user-generated content. The 56 ray tracing cores are also present, though the impact of ray tracing in Roblox is not measured in the dataset.

The GPU's memory subsystem is particularly relevant to Roblox. While the game is not typically considered a VRAM-heavy title, the 16 GB frame buffer at 644.6 GB/s ensures that memory bandwidth is never a bottleneck, even at 4K resolution with high settings. The fact that the 4K High setting averages 144 FPS suggests the GPU is delivering enough memory throughput to sustain high frame rates without degradation. The GPU benchmark percentile vs all GPUs is 69, indicating it performs better than most other GPUs in synthetic tests, though its nearest rivals include less capable mobile parts like the RTX 3080 Mobile and the RX 6800S.

Resolution Scaling

The measured FPS data reveals how the system's performance scales when moving from 1080p to 4K, and this scaling highlights the nature of the bottleneck. At 1080p High, the system averages 381 FPS. At 1440p High, the average drops to 254 FPS, and at 4K High, it falls to 144 FPS. The decrease from 1080p to 1440p is 127 FPS (a 33% reduction), while the decrease from 1440p to 4K is 110 FPS (a 43% reduction). This indicates that the GPU becomes a more significant factor as resolution increases, but the game maintains high performance.

The Ultra setting offers a different scaling pattern. At 1080p Ultra, the average is 309 FPS. At 1440p Ultra, it is 206 FPS, and at 4K Ultra, it is 117 FPS. The percentage drops are 33% and 43% respectively, mirroring the High setting's trend. This consistent scaling across settings suggests that the GPU's rendering load scales linearly with resolution, which is expected for a game like Roblox that does not have heavy compute work. However, the absolute frame rates at 4K remain high, with even the Ultra setting hitting 117 FPS, which is well above common refresh rates.

The data for the Low setting shows the least impact from resolution. At 1080p Low, the average is 474 FPS. At 1440p Low, it is 316 FPS, and at 4K Low, it is 179 FPS. This represents a drop of 33% from 1080p to 1440p and a further 43% from 1440p to 4K. The fact that even at Low settings the 4K frame rate is 179 FPS implies that the CPU is not a limiting factor even when the GPU has less work. The system is consistently delivering high frame rates, and the resolution scaling indicates that the GPU is the primary component being stressed.

The Medium setting provides the only data with minimum and maximum FPS values. At 1080p Medium, the average is 431 FPS with a range of 367 to 496 FPS. At 1440p Medium, the average is 288 FPS with a range of 245 to 331 FPS. At 4K Medium, the average is 163 FPS with a range of 138 to 187 FPS. The frame time variance is consistent across resolutions, suggesting that the game's frame pacing is stable. The data shows that the system is never CPU-bound at any resolution, as even the lowest frame rates are well above 60 FPS.

Settings Recommendations

The benchmark data includes four settings presets at each resolution. The best choice depends on the target display's refresh rate. For a standard 60 Hz display, all settings and resolutions provide more than enough performance. For a high-refresh-rate display, the choice becomes more nuanced.

At 1080p, the Medium setting appears to be the sweet spot. It averages 431 FPS, which is 53 FPS higher than High and 122 FPS lower than Low. The Low setting averages 474 FPS, but the Medium setting offers 431 FPS with presumably better visual quality. The Ultra setting averages 309 FPS, which is still high but a 122 FPS drop from Medium. The measured frame range at Medium (367-496 FPS) suggests good consistency. For most users, Medium at 1080p will provide visual quality at a frame rate that exceeds the refresh rate of most gaming monitors.

At 1440p, the Medium setting again stands out. It averages 288 FPS, which is 34 FPS higher than High (254 FPS) and 82 FPS lower than Low (316 FPS). The Ultra setting drops to 206 FPS, which is still very high. The range at Medium is 245 to 331 FPS, which is a wide but acceptable range. For users with a 144 Hz or even 240 Hz monitor, Medium at 1440p is the best choice, as it provides 288 FPS, which is more than enough to saturate even the fastest refresh rates.

At 4K, the choice is more critical. The Low setting averages 179 FPS, which is the highest. The Medium setting averages 163 FPS, High averages 144 FPS, and Ultra drops to 117 FPS. For a 4K display with a 120 Hz refresh rate, the Ultra setting is just below the refresh rate, while the High setting is comfortably above it. The Medium setting provides 163 FPS, which is a solid option for 144 Hz 4K displays, though 4K 144 Hz panels are rare. For a 4K 60 Hz display, any setting will be more than adequate.

The data shows that the Medium setting is the most efficient choice, because it always provides a noticeable frame rate improvement over High and Ultra while still delivering a high level of visual quality. The difference between Medium and High is substantial: at 1080p the gap is 50 FPS, at 1440p it is 34 FPS, and at 4K it is 19 FPS. This suggests that the High preset has a disproportionately high cost for the frame rate it delivers. The Ultra setting is even more expensive relative to the Medium, with a 122 FPS drop at 1080p, 82 FPS at 1440p, and 46 FPS at 4K. For the best experience per measured row, Medium is the recommended preset across all resolutions.

Measured FPS Breakdown

The measured FPS data provides a precise breakdown of performance across all tested configurations. At 1920x1080, the system averages 474 FPS on Low, 431 FPS on Medium, 381 FPS on High, and 309 FPS on Ultra. The Medium setting has a minimum of 367 FPS and a maximum of 496 FPS, showing a 129 FPS range. The other settings have no min/max data. The 1080p results show very high frame rates, with all settings exceeding 300 FPS.

At 2560x1440, the average FPS values are 316 for Low, 288 for Medium, 254 for High, and 206 for Ultra. The Medium setting has a minimum of 245 FPS and a maximum of 331 FPS, a range of 86 FPS. The drop from 1080p is significant, but the performance is still very high. For example, the High setting at 1440p (254 FPS) is higher than the High setting at 1080p for many other systems.

At 3840x2160, the average FPS values are 179 for Low, 163 for Medium, 144 for High, and 117 for Ultra. The Medium setting has a minimum of 138 FPS and a maximum of 187 FPS, a range of 49 range. This is the smallest frame range of any resolution, indicating that the game is more stable at 4K. The 4K Ultra setting produces the lowest average of any tested configuration, but 117 FPS is still a very smooth experience.

The scaling from 1080p to 4K for each setting is as follows: Low drops from 474 to 179 FPS (a 62% decrease), Medium drops from 431 to 163 FPS (a 62% decrease), High drops from 381 to 144 FPS (a 62% decrease), and Ultra drops from 309 to 117 FPS (a 62% decrease). The consistency of this percentage drop across settings shows that the GPU's rasterization performance scales in a linear fashion with resolution, and that the CPU does not become a bottleneck at any point. The system maintains a high frame rate even in the most demanding test case (4K Ultra, 117 FPS), which is well above the 60 Hz refresh rate of most displays.

The data does not include any minimum or maximum FPS values for the Low, High, or Ultra settings, only for Medium. The Medium setting's min and max values are the only measure of frame-time variance, and they show a tightening of frame range as resolution increases: the range is 129 FPS at 1080p, 86 FPS at 1440p, and 49 FPS at 4K. This suggests that the frame pacing becomes more consistent at higher resolutions, likely because the GPU is the limiting factor and the CPU has less relative influence. Overall, the measured FPS data shows that this system is well-balanced for Roblox, handles all resolutions and settings with ease, and provides a very high-performance experience.
