Roblox

Roblox is a sandbox title that scales surprisingly well across a wide range of hardware, and the combination of the AMD Ryzen 7 9850X3D and NVIDIA GeForce RTX 4070 produces an exceptionally high-performing setup. The measured frame rates in this dataset show that the system is capable of delivering fluid gameplay even at 4K Ultra, though the data also reveals a clear shift in performance bottlenecks as resolution and settings change. This analysis walks through the measured FPS, the scaling behavior, and the specific roles the CPU and GPU play in these results.

Resolution Scaling

The data for this Roblox configuration shows a predictable and steep decline in average frame rates as resolution increases from 1920x1080 to 3840x2160. At the High preset, the average FPS drops from 404 at 1080p to 270 at 1440p, and finally to 153 at 4K. This represents a 33% reduction in performance when moving from 1080p to 1440p, and a further 43% reduction when moving from 1440p to 4K. The overall scaling from 1080p to 4K at High settings is a 62% drop in average FPS.

The Low preset shows a similar pattern, with average FPS figures of 503 at 1080p, 335 at 1440p, and 190 at 4K. The percentage drop from 1080p to 1440p is 33%, and from 1440p to 4K is 43%, which mirrors the High preset scaling almost exactly. This consistency suggests that the performance scaling is largely resolution-bound rather than settings-bound in this range.

Looking at the Medium preset, which includes minimum and maximum FPS values, the scaling continues. The average FPS at 1080p is 457, dropping to 305 at 1440p and 173 at 4K. The minimum FPS also decreases from 389 at 1080p to 259 at 1440p and 147 at 4K. The maximum FPS drops from 526 at 1080p to 351 at 1440p and 199 at 4K.

The Ultra preset demonstrates the most significant performance hit. At 1080p, the average FPS is 328. At 1440p, it falls to 219, and at 4K, it drops to 124. The scaling from 1080p to 4K at Ultra is a 62% reduction, which is consistent with the other presets.

These numbers indicate that the GPU is the primary limiting component at 4K, as the frame rate reduction is substantial across all settings. The fact that the percentage drop from 1440p to 4K is consistently around 43% regardless of preset suggests that the pixel fill rate and memory bandwidth demands of 4K are the dominant factors. At 1080p, however, the extremely high frame rates (over 500 FPS on Low) suggest that the CPU, with its high single-core performance, is keeping up with the GPU's output at lower resolutions.

GPU Role

The NVIDIA GeForce RTX 4070 plays a central role in determining the frame rates at higher resolutions in Roblox. The GPU features an AD104 chip on the Ada Lovelace architecture, built on a 5 nm process. It has 5888 shading units, 184 texture mapping units, and 64 raster output units. The boost clock is rated at 2475 MHz, with a base clock of 1920 MHz.

The memory subsystem is a key factor. The GPU has 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. The memory clock is listed as 1313 MHz, which translates to 21 Gbps effective. This bandwidth is sufficient for the 4K workloads in Roblox, as evidenced by the playable frame rates at that resolution.

The GPU's compute capabilities are substantial. It offers 29.15 TFLOPS of FP32 performance and a similar 29.15 TFLOPS for FP16, indicating a 1:1 ratio. The pixel rate is 158.4 GPixel/s, and the texture rate is 455.4 GTexel/s. These specifications support the high frame rates observed, particularly at lower resolutions where the GPU is less constrained.

In the context of this game, the GPU's performance percentile is 81 among all GPUs, with an average benchmark score of 37648. Its nearest rivals in benchmark scores include the NVIDIA Tesla P4 (0.1% higher), the AMD Radeon RX Vega 56 (0.4% higher), and the NVIDIA GeForce RTX 4080 Mobile (1.3% lower). The RTX 4070 also trails the AMD Radeon PRO W6400 by 1.3%.

The data shows that at 4K, the GPU is the limiting factor. The average FPS at 4K Ultra is 124, which is a 62% reduction from the 1080p Ultra score of 328. This scaling is consistent with a GPU-bound scenario where the rendering resolution directly impacts performance. The GPU's role is less dominant at 1080p, where frame rates exceed 400 FPS on most presets, indicating that the CPU's performance is sufficient to feed the GPU at that resolution.

Measured FPS Breakdown

The dataset provides average FPS measurements for three resolutions (1920x1080, 2560x1440, 3840x2160) across four settings presets (Low, Medium, High, Ultra). The Medium preset is the only one that includes minimum and maximum FPS values.

At 1920x1080, the Low preset achieves an average of 503 FPS. The Medium preset averages 457 FPS, with a minimum of 389 and a maximum of 526. The High preset averages 404 FPS, and the Ultra preset averages 328 FPS. The spread from Low to Ultra is 175 FPS, or 35% lower performance at Ultra compared to Low.

At 2560x1440, the average FPS for Low is 335. The Medium preset averages 305 FPS, with a minimum of 259 and a maximum of 351. The High preset averages 270 FPS, and the Ultra preset averages 219 FPS. The difference between Low and Ultra at this resolution is 116 FPS, a 35% reduction.

At 3840x2160, the Low preset averages 190 FPS. The Medium preset averages 173 FPS, with a minimum of 147 and a maximum of 199. The High preset averages 153 FPS, and the Ultra preset averages 124 FPS. The difference between Low and Ultra is 66 FPS, a 35% reduction.

A notable pattern emerges: the percentage difference between Low and Ultra is consistently 35% across all three resolutions. This suggests that the settings preset scaling is uniform, meaning the additional load from Ultra settings is a consistent multiplier on the rendering cost. The minimum FPS values for Medium settings show that even at 4K, the frame rate does not drop below 147, which is well above the threshold for smooth gameplay.

The data also shows that the High preset sits roughly halfway between Medium and Ultra in performance. At 1080p, High is 404 FPS, which is 53 FPS lower than Medium and 76 FPS higher than Ultra. At 1440p, High is 270 FPS, which is 35 FPS lower than Medium and 51 FPS higher than Ultra. At 4K, High is 153 FPS, which is 20 FPS lower than Medium and 29 FPS higher than Ultra.

How This Combo Ranks

The AMD Ryzen 7 9850X3D and NVIDIA GeForce RTX 4070 combination ranks 666 out of 3010 tested combos in Roblox. This places the system in the top 22% of all tested combinations, which is a strong result given the game's broad hardware compatibility.

The combo rank of 666 indicates that there are 665 other hardware combinations that achieve higher average FPS in Roblox. However, this rank should be interpreted in context with the measured frame rates. The system achieves over 120 FPS at 4K Ultra and over 300 FPS at 1080p Ultra, which are exceptionally high performance levels for most gaming scenarios.

The CPU's contribution to this rank is significant. The Ryzen 7 9850X3D has a percentile rank of 92 among all CPUs, with an average benchmark score of 58386. Its nearest rival, the Intel Xeon Platinum 8260M, scores 58323, which is 0.1% lower. The Intel Core i9-14900 scores 58115, which is 0.5% lower. The CPU's high percentile rank suggests it is not a bottleneck in most gaming workloads.

The GPU's percentile rank is 81 among all GPUs, with an average benchmark score of 37648. This is lower than the CPU's percentile, which indicates that the GPU is more likely to be the limiting component in demanding scenarios. The GPU's nearest rival, the NVIDIA Tesla P4, scores 37628, which is 0.1% lower. The AMD Radeon RX Vega 56 scores 37507, which is 0.4% lower.

The combination of a top-tier CPU and a high-end GPU results in a system that ranks in the top quarter of all tested combos. The data suggests that for Roblox, which is not typically a GPU-intensive game, the CPU's strong single-core performance (as seen in its Cinebench R23 single-core score of 2228) is crucial for achieving the high frame rates observed at lower resolutions.

CPU Role

The AMD Ryzen 7 9850X3D is a significant contributor to the high frame rates in Roblox, particularly at 1080p and 1440p. The CPU has 8 cores and 16 threads, based on the Zen 5 architecture on a 4 nm process. The base clock is 4.70 GHz, with a boost clock of 5.60 GHz. It has a 96 MB shared L3 cache, which is a substantial amount for gaming workloads.

The CPU's synthetic benchmarks indicate strong performance. In Cinebench R23, it scores 22807 in multicore and 2228 in single-core. The single-core score is particularly relevant for Roblox, which often has performance characteristics that are sensitive to single-threaded performance. The Passmark single-thread score is 4704, further confirming strong single-core capabilities.

The CPU's average benchmark score is 58386, with a percentile rank of 92. Its nearest rivals include the Intel Xeon Platinum 8260M (0.1% higher), the Intel Core i9-14900 (0.5% higher), and the AMD Ryzen AI 9 HX 470 (0.7% lower). The Intel Xeon w5-2545 is 0.2% higher.

In Roblox, the CPU's role is most evident at 1080p. The average FPS at 1080p Low is 503, which is a very high frame rate that requires the CPU to process game logic and draw calls quickly. The CPU's high boost clock of 5.60 GHz and large L3 cache help in this regard. The data shows that the CPU is capable of keeping up with the GPU at 1080p, as the frame rate is not limited by the CPU at this resolution.

At 4K, the CPU's role diminishes, as the GPU becomes the primary bottleneck. However, the CPU's performance ensures that it does not cause frame drops, as evidenced by the minimum FPS of 147 at 4K Medium. The CPU's 16 threads and high memory bandwidth support (89.6 GB/s) ensure that it can handle the game's background tasks without impacting frame times.

Settings Recommendations

Based on the measured FPS data, the optimal settings preset depends on the target resolution and the desired frame rate. The data shows that all presets are playable at all resolutions, but the experience varies significantly.

At 1920x1080, the Low preset achieves 503 FPS, which is well beyond the refresh rate of most monitors. The Medium preset at 457 FPS is also extremely high, and the High preset at 404 FPS offers a good balance. The Ultra preset at 328 FPS is still very high, but the visual quality improvement may not justify the 35% performance drop from Low. For 1080p gaming, the High preset is recommended as it provides a significant visual upgrade over Low while maintaining a very high frame rate.

At 2560x1440, the Low preset averages 335 FPS, the Medium preset averages 305 FPS, and the High preset averages 270 FPS. The Ultra preset at 219 FPS is still well above 60 FPS and would be suitable for high-refresh-rate monitors. The Medium preset offers a good balance, with a minimum FPS of 259, which ensures smooth gameplay. For 1440p, the High preset is recommended for the best visual quality to performance ratio, as it maintains over 270 FPS average.

At 3840x2160, the Low preset averages 190 FPS, which is high for 4K. The Medium preset averages 173 FPS with a minimum of 147, ensuring a smooth experience. The High preset at 153 FPS is also playable, while the Ultra preset at 124 FPS is the lowest average in the dataset. For 4K gaming, the Medium preset is recommended, as it offers a good balance of visual quality and performance, with a minimum FPS of 147 that ensures no noticeable stuttering.

The data indicates that the Medium preset is the most versatile option across all resolutions. It is the only preset with recorded minimum and maximum FPS values, showing a stable frame delivery. The performance scaling from Low to Ultra is consistent at 35%, but the Medium preset provides a middle ground that is both visually acceptable and performant. For users prioritizing the highest frame rates, the Low preset is the best choice, while those seeking the best visuals at 4K should use the Ultra preset, as the 124 FPS average is still well above standard display refresh rates.
