GPU Role

The NVIDIA GeForce RTX 3070, built on the Ampere architecture with an 8nm process, is the primary driver for high-resolution rendering in Roblox. Its memory configuration includes 8 GB of GDDR6 on a 256-bit bus, delivering a bandwidth of 448.0 GB/s. The GPU operates at a base clock of 1500 MHz with a boost clock of 1725 MHz, and its memory runs at 1750 MHz or 14 Gbps effective. These specifications support the card’s ability to handle the game’s geometry and textures, which is reflected in the measured FPS data.

The RTX 3070’s general performance, with a Passmark G3D score of 22214 and an average benchmark score of 17208, establishes its capability tier. In Roblox, the GPU’s role becomes more apparent at higher resolutions. The transition from 1080p to 4K shows a significant FPS drop across all settings, indicating that the graphics card is being tasked with more pixel processing. For instance, at High settings, the average FPS drops from 332 at 1920x1080 to 125 at 3840x2160, a reduction that underscores the GPU’s workload. The card’s 5888 shading units and 96 ROPs are the architectural components responsible for this pixel throughput, though the FPS figures themselves are the clearest indicator of its performance envelope.

How This Combo Ranks

The ranking data places this specific CPU-GPU pairing at 1596 out of 3711 total combinations tested in Roblox. This position in the 43rd percentile of all combos indicates that while this system is not at the top tier, it outperforms a majority of the tested configurations. The ranking reflects the combined capabilities of the Ryzen 5 8400F and RTX 3070, which together produce very high frame rates that are likely beyond the refresh rate of most displays.

Interpreting this rank requires context. With an average FPS of 270 at 1080p Ultra, the system is far above the threshold for smooth gameplay, suggesting that the rank is not limited by raw performance in this title. Instead, the 43rd percentile might reflect the presence of many combos with even more powerful GPUs or CPUs that push frame rates into the 500-600 FPS range. The data shows that this combo sits in a performance bracket where the game is thoroughly playable at maximum settings, but where other configurations with higher-end components achieve even higher absolute frame counts. The GPU’s 61st percentile ranking and the CPU’s 77th percentile ranking both contribute to this overall position, with the CPU being a relatively stronger component in general benchmarks.

Measured FPS Breakdown

The measured data provides a comprehensive view of performance across three resolutions and four settings presets.

At 1920x1080, the average frame rates range from 270 to 413 FPS. Low settings yield 413 FPS, Medium produces 376 FPS (with a minimum of 320 and maximum of 432), High delivers 332 FPS, and Ultra drops to 270 FPS. These figures are all exceptionally high, indicating that at 1080p, the system is heavily CPU-bound or limited by the game engine’s frame pacing, as even the lowest preset exceeds 400 FPS.

Moving to 2560x1440, average frame rates decrease by approximately 33-35% across all settings. Low settings produce 276 FPS, Medium yields 251 FPS (with a range of 213 to 289), High delivers 222 FPS, and Ultra drops to 180 FPS. The scaling from 1080p to 1440p is consistent, suggesting a balanced workload shift between CPU and GPU.

At 3840x2160, the averages fall further. Low settings achieve 156 FPS, Medium produces 142 FPS (with a minimum of 121 and maximum of 163), High delivers 125 FPS, and Ultra drops to 102 FPS. The 4K results show a more pronounced gap between Low and Ultra, with the difference being 54 FPS compared to 143 FPS at 1080p, indicating that the GPU becomes the limiting factor at this resolution.

The Medium settings data is the only set with min and max values, providing insight into frame time consistency. At 1080p Medium, the spread is 112 FPS (320-432), at 1440p Medium it is 76 FPS (213-289), and at 4K Medium it is 42 FPS (121-163). The shrinking spread at higher resolutions suggests that frame pacing becomes more stable as the GPU takes on a larger share of the workload.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial and reveals the nature of the performance bottleneck. At High settings, the average FPS falls from 332 at 1920x1080 to 222 at 2560x1440, a reduction of 33.1%. Moving from 1440p to 4K, the FPS falls from 222 to 125, a reduction of 43.7%. The total drop from 1080p to 4K High is 62.3%.

For Low settings, the scaling is similar in percentage terms. The FPS drops from 413 at 1080p to 276 at 1440p (33.2% reduction), then to 156 at 4K (43.5% reduction from 1440p). The total drop from 1080p to 4K Low is 62.2%.

This consistent pattern across settings indicates that the scaling is primarily driven by resolution’s impact on the GPU. The pixel count quadruples from 1080p to 4K, but the FPS does not drop by a comparable factor, suggesting that the game’s rendering load does not scale linearly with resolution, or that the CPU is still contributing to performance at 1080p. The fact that the FPS drop from 1440p to 4K is steeper than from 1080p to 1440p in percentage terms points to the GPU being the clear limiting component at higher resolutions. At 1080p, the system is likely CPU-limited, as the CPU’s 6 cores and 12 threads can feed frames faster than the GPU can render them, but beyond 1440p, the GPU’s pixel fill rate and memory bandwidth become the constraint.

Settings Recommendations

The measured data across the four presets allows for a clear recommendation based on performance margins. At every resolution, the Low preset delivers the highest average frame rate, but the differences between presets vary. At 1080p, the jump from Low to Ultra costs 143 FPS (413 to 270), which is a 34.6% performance reduction for the visual quality increase.

For users with a 60 Hz display, any setting at any resolution is sufficient, as even 4K Ultra produces 102 FPS. For a 144 Hz display, 4K Medium (142 FPS) or 4K Low (156 FPS) are viable options, while at 1440p, all settings exceed 180 FPS. For a 240 Hz display, 1080p Ultra (270 FPS) is the only 1080p preset that falls below the threshold, while 1440p Low (276 FPS) and 1440p Medium (251 FPS) also fail to reach 240 FPS consistently.

The data suggests that the Medium preset offers the best balance between visual fidelity and performance headroom. At 4K, Medium (142 FPS) is only 9% slower than Low (156 FPS) but provides a significant visual upgrade over Low. At 1440p, Medium (251 FPS) is within 9% of Low (276 FPS) and delivers noticeably better visuals. The availability of min and max values for Medium also confirms that frame times are stable, with the spread at 4K being only 42 FPS. For users prioritizing maximum frame rates for competitive play, Low settings at 1080p provide the highest headroom, but for general use, Medium or High at 1440p or 4K offers a superior experience without sacrificing playability.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, manufactured on a 4nm process by TSMC. It has a base clock of 4.20 GHz and a boost clock of 4.70 GHz, with a 16 MB shared L3 cache. The CPU supports DDR5 memory on a dual-channel bus, providing a memory bandwidth of 83.2 GB/s. Its general benchmark performance is strong, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943, placing it in the 77th percentile of all CPUs.

In the context of Roblox, the CPU’s role is primarily to maintain high frame rates at lower resolutions. The data shows that at 1080p, the FPS is exceptionally high (270-413 FPS depending on settings), which suggests that the CPU is capable of feeding the GPU with enough draw calls and game logic updates to sustain these rates. The CPU’s 6 cores are likely sufficient for Roblox’s single-threaded or lightly-threaded workload, as evidenced by the strong single-core performance in Cinebench R23 (2943) and 3DMark single-thread (951).

The CPU’s influence wanes at higher resolutions. The FPS drop from 1080p to 4K is more attributable to the GPU’s rendering load than to CPU limitations, as the CPU is likely not fully saturated at 4K. The CPU’s 12 threads provide headroom for background tasks, but the game’s performance ceiling at 4K is set by the RTX 3070. The CPU’s percentile ranking of 77% versus the GPU’s 61% suggests that in this pairing, the CPU is relatively more capable, and the GPU is the more likely bottleneck in demanding scenarios. The measured FPS at 1080p Low (413 FPS) confirms the CPU’s ability to drive high frame rates, though this figure also indicates that the game engine itself may cap performance around this level regardless of hardware.
