Roblox

Roblox with an AMD Ryzen 5 4600G and NVIDIA GeForce RTX 4070 produces frame rates that are extremely high across all tested configurations, but the scaling pattern from 1080p to 4K reveals a system that is primarily bounded by CPU performance at lower resolutions and becomes increasingly GPU-limited as resolution climbs. The measured data shows that at 1080p Low, the combo reaches 503 FPS, while at 4K Ultra it drops to 124 FPS, a reduction of roughly 75% from the peak. This wide spread indicates that the RTX 4070 has ample headroom at lower resolutions, where the Ryzen 5 4600G's single-thread performance becomes the limiting factor, while the GPU's rendering load dominates at 4K.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The frame rate progression across resolutions follows a clear pattern of diminishing returns as pixel count increases. At 1080p with Low settings, the system produces 503 FPS, which drops to 335 FPS at 1440p and further to 190 FPS at 4K. This represents a 33% reduction from 1080p to 1440p and a 43% reduction from 1440p to 4K, showing that the scaling penalty is not linear but steepens as resolution increases. For High settings, the progression is 404 FPS at 1080p, 270 FPS at 1440p, and 153 FPS at 4K, with similar percentage drops of 33% and 43% respectively.

These figures indicate that at 1080p, the system is heavily CPU-bound. The jump from 1080p Low (503 FPS) to 1440p Low (335 FPS) is a 168 FPS difference, which is substantial, but the fact that the RTX 4070 can still push over 300 FPS at 1440p suggests the GPU is not yet saturated. The 4K results tell a different story: at 4K Low (190 FPS) versus 4K High (153 FPS), the gap is only 37 FPS, whereas at 1080p the gap between Low and High is 99 FPS. This compression of frame rates at 4K across settings indicates that the GPU's pixel throughput becomes the dominant constraint, as increasing settings has a smaller relative impact when the resolution is already demanding.

The Ultra preset results reinforce this interpretation. At 1080p Ultra, the system delivers 328 FPS, which is still very high but 175 FPS below the 1080p Low result. At 4K Ultra, the system drops to 124 FPS, which is the lowest measured value in the entire dataset. The scaling from 1440p Ultra (219 FPS) to 4K Ultra (124 FPS) is a 43% reduction, matching the pattern seen in other settings, which suggests that the GPU's rendering pipeline is the bottleneck at this resolution regardless of the quality preset chosen.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor based on the Zen 2 architecture, with a base clock of 3.70 GHz and a boost clock of 4.20 GHz. Its benchmark scores show a significant gap between single-threaded and multi-threaded performance: the Cinebench R23 single-core score is 1919, while the multi-core score is 13593, a ratio of roughly 7:1. In Roblox, which is known for being lightly threaded, the single-core performance is likely the more relevant metric for frame rate generation at lower resolutions.

The data supports this hypothesis. At 1080p Low, the system reaches 503 FPS, which is well above what most displays can show, but the fact that this number is not higher suggests the CPU's single-thread limit is being approached. The 3DMark single-thread score of 726 and the PassMark single-thread score of 2653 both place this processor in the mid-range for single-core throughput. When the resolution is lowered to 1080p, the GPU has excess capacity, and the CPU's ability to feed draw calls and physics calculations becomes the limiting factor.

The Ryzen 5 4600G's multi-threaded capability, while not the primary driver in Roblox, still matters for background tasks and overall system responsiveness. Its Cinebench R20 multi-core score of 5709 and Geekbench multi-core score of 6637 indicate solid parallel performance, but the game's engine does not appear to scale well with additional threads, as evidenced by the fact that the 1080p Low result (503 FPS) is only 25% higher than the 1440p Low result (335 FPS), a difference that is more attributable to resolution than CPU threading.

The processor's 8 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth are adequate for the game's needs, but the boost clock of 4.20 GHz is the key specification for Roblox's single-threaded workload. The data shows that at 1080p, the system cannot exceed 503 FPS even at Low settings, which suggests that this is the ceiling imposed by the CPU's single-thread performance in this particular game.

How This Combo Ranks — use comboRankInGame vs other tested combos

Among the 3711 tested combinations in the database, this specific pairing of the Ryzen 5 4600G and RTX 4070 achieves a rank of 866 in Roblox. This places it in the top 23% of all tested combos, which is a strong showing given that the CPU is a mid-range part from 2020 while the GPU is a high-end model from 2023. The percentile ranking of the CPU alone is 71, meaning it outperforms 71% of all CPUs in the database, while the GPU's percentile is 81, outperforming 81% of all GPUs.

The rank of 866 out of 3711 suggests that while this combo produces very high frame rates in absolute terms, there are many other combinations that achieve even higher performance in Roblox. This is likely because the game is so CPU-sensitive at lower resolutions that pairing a more powerful CPU with the same GPU would yield higher frame rates. The nearest rivals to the Ryzen 5 4600G in terms of average benchmark score provide context: the AMD Ryzen 3 PRO 5355GE scores 17482 (0.1% higher), the AMD Ryzen 3 8300GE scores 17614 (0.6% lower), the Intel Core 7 150U scores 17395 (0.6% higher), and the Intel Core i3-14100T scores 17648 (0.8% lower).

These rival CPUs are all within 1% of the Ryzen 5 4600G's average benchmark score of 17507, indicating that the CPU is not an outlier in its performance class. The fact that the combo still ranks at 866 suggests that the GPU is doing most of the heavy lifting in achieving high frame rates, and that the CPU's contribution is sufficient but not exceptional for Roblox. The rank also implies that users with higher-performing CPUs, even paired with slightly weaker GPUs, could potentially achieve better results in this specific game.

Q: Is the Ryzen 5 4600G's integrated graphics relevant for this configuration?

A: The Ryzen 5 4600G includes Radeon Vega 7 integrated graphics, but in this configuration, the discrete RTX 4070 is always used for rendering Roblox. The integrated graphics specification is part of the CPU's feature set, but the benchmark data exclusively reflects the discrete GPU's performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process and features 12 GB of GDDR6X memory on a 192-bit bus, providing 504.2 GB/s of memory bandwidth. Its boost clock is 2475 MHz, and it contains 5888 shading units, 184 texture mapping units, and 64 raster operation units. These specifications make it a high-end GPU that is well-suited for modern games, but Roblox's relatively simple graphics engine means that the GPU's raw compute power is not fully utilized at lower resolutions.

The GPU's benchmark scores demonstrate its capabilities: a 3DMark Steel Nomad DX12 score of 3854, a Geekbench OpenCL score of 154858, and a PassMark G3D score of 26927. These scores place the RTX 4070 in the 81st percentile of all GPUs, and its nearest rivals include the NVIDIA Tesla P4 (0.1% higher), AMD Radeon RX Vega 56 (0.4% higher), NVIDIA GeForce RTX 4080 Mobile (1.3% lower), and AMD Radeon PRO W6400 (1.3% higher). The GPU's average benchmark score is 37648, which is significantly higher than the CPU's average score of 17507, underscoring that the GPU is the more dominant component in this pairing.

In Roblox, the GPU's role becomes more prominent as resolution increases. At 4K, the pixel count is four times that of 1080p, and the GPU's fill rate and memory bandwidth become critical. The RTX 4070's pixel rate of 158.4 GPixel/s and texture rate of 455.4 GTexel/s are sufficient to maintain 124 FPS at 4K Ultra, but the drop from 153 FPS at 4K High to 124 FPS at 4K Ultra shows that the additional graphical effects in the Ultra preset take a toll on GPU performance. The 12 GB VRAM capacity is more than adequate for Roblox, as the game's textures and geometry are not particularly memory-intensive, and the data shows no signs of VRAM-related stuttering or frame rate degradation at any resolution.

Settings Recommendations — which preset gives the best experience per the measured rows

For users with a 60 Hz display, even the most demanding configuration measured — 4K Ultra at 124 FPS — provides more than double the refresh rate, meaning all settings are playable. However, the data reveals that the Medium preset offers the best balance of visual quality and performance across all resolutions. At 1080p Medium, the system delivers 457 FPS with a minimum of 389 FPS, which is only 46 FPS lower than Low settings but provides a significant visual upgrade. At 1440p Medium, the average is 305 FPS with a minimum of 259 FPS, still far above any display's refresh rate. At 4K Medium, the average is 173 FPS with a minimum of 147 FPS, ensuring that even the frame rate dips stay above 144 Hz.

The High preset is also viable, with 404 FPS at 1080p, 270 FPS at 1440p, and 153 FPS at 4K. However, the jump from Medium to High at 4K costs 20 FPS (from 173 to 153), while the jump from High to Ultra costs another 29 FPS (from 153 to 124). This diminishing return suggests that Medium is the sweet spot for 4K, as it provides the highest frame rates while still delivering improved visuals over Low. For competitive play where maximum frame rate is paramount, Low settings at 1080p (503 FPS) or 1440p (335 FPS) would be the choice, but for most users, Medium at 1440p offers the best combination of smoothness and fidelity.

The Ultra preset, while visually the most demanding, still produces excellent results at 1080p (328 FPS) and 1440p (219 FPS), but at 4K it drops to 124 FPS. Given that the minimum FPS data is only available for the Medium preset at each resolution, the lack of min/max data for other presets means we cannot assess frame time consistency for Low, High, or Ultra. The Medium preset's minimum FPS values — 389 at 1080p, 259 at 1440p, and 147 at 4K — indicate that even the lowest frame rates are well above typical display refresh rates, making Medium the recommended preset for its combination of performance and stability.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce an average of 503 FPS, Medium produces 457 FPS with a minimum of 389 FPS and maximum of 526 FPS, High produces 404 FPS, and Ultra produces 328 FPS. The spread from Low to Ultra is 175 FPS, showing that settings have a substantial impact at this resolution. The Medium preset's minimum of 389 FPS is notable because it is higher than the average FPS of the High preset (404 FPS is close, but 389 minimum is lower than 404 average), suggesting that Medium provides more consistent performance than the average FPS alone would indicate.

At 2560x1440, the frame rates remain very high but show the expected reduction from 1080p. Low settings produce 335 FPS, Medium produces 305 FPS with a minimum of 259 FPS and maximum of 351 FPS, High produces 270 FPS, and Ultra produces 219 FPS. The difference between Low and Ultra is 116 FPS, which is a smaller absolute gap than at 1080p but a similar percentage reduction. The Medium preset's maximum of 351 FPS is close to the Low preset's average of 335 FPS, indicating that the Medium preset can occasionally reach performance levels comparable to Low.

At 3840x2160, the system shows its most constrained performance. Low settings produce 190 FPS, Medium produces 173 FPS with a minimum of 147 FPS and maximum of 199 FPS, High produces 153 FPS, and Ultra produces 124 FPS. The gap between Low and Ultra is 66 FPS, which is the smallest absolute difference across all resolutions, confirming that the GPU is the primary bottleneck at 4K. The Medium preset's minimum of 147 FPS is still above 144 Hz, making it suitable for high-refresh-rate displays, while the Ultra preset's 124 FPS average is the only measured configuration that falls below 144 FPS.
