Roblox

The AMD Ryzen 5 4600G paired with the NVIDIA GeForce RTX 4080 is an unusual combination: a budget-oriented 6-core Zen 2 APU with an integrated Radeon Vega 7, mated to one of the fastest consumer GPUs on the market. In Roblox, this pairing yields extremely high frame rates across the board. The measured data shows that the RTX 4080 is never the limiting factor at any resolution tested; the CPU, with its 3.70 GHz base and 4.20 GHz boost clocks, can feed the GPU enough data to produce triple-digit averages even at 4K. The result is that the user can prioritize visual quality and still maintain competitive frame rates, though the optimal preset depends on whether the goal is maximum smoothness or maximum detail.

Settings Recommendations

For the best experience per the measured rows, the Medium preset offers the most balanced combination of visual quality and performance. At 1080p, Medium averages 585 FPS with a minimum of 497 FPS and a maximum of 673 FPS. This is only 21 FPS below the High preset’s 517 average, but it is a full 165 FPS above the Ultra preset’s 420 average. The minimum FPS figure of 497 is also the highest minimum recorded at 1080p, suggesting that Medium provides a more stable frame delivery than High, which has no reported minimum. Moving to 2560x1440, Medium averages 390 FPS with a minimum of 332 and a maximum of 449. The 332 FPS minimum is still far above any refresh rate on the market, so the stability is less of a concern. At 4K, Medium averages 221 FPS with a minimum of 188 and a maximum of 254, making it the only 4K preset with a reported minimum and maximum. That 188 FPS minimum is still far above the refresh rate of most displays, but it indicates that even in the most demanding scenes, the frame rate stays well above the 144 Hz threshold.

The Low preset provides the highest averages at every resolution, but the visual quality loss is usually not worth the extra frame rate. At 1080p Low, the average is 606 FPS, which is only 21 FPS higher than Medium. At 1440p, Low averages 429 FPS compared with Medium's 390 FPS, a 39 FPS difference. At 4K, Low averages 243 FPS vs 221 FPS for Medium, a 22 FPS difference. These differences are negligible in practice. The Ultra preset, meanwhile, is the only one that can cause the frame rate to dip below the 200 FPS mark at 4K, with an average of 158 FPS. That is still very playable, but the 221 FPS average of Medium at 4K is a more comfortable margin for high refresh rate displays. The data suggests that Medium is the sweet spot: it provides a minimum 188 FPS at 4K, a 332 FPS minimum at 1440p, and a 497 FPS minimum at 1080p, all while offering more graphical fidelity than Low.

GPU Role

The NVIDIA GeForce RTX 4080 is a Gen 3.5 graphics card with 16 GB of GDDR6X memory on a 256-bit bus, delivering 716.8 GB/s of bandwidth. Its base clock is 2205 MHz with a boost clock of 2505 MHz, and it contains 9728 shading units, 304 texture mapping units, and 112 render output units. The memory runs at 1400 MHz, which translates to 22.4 Gbps effective. The card is built on the Ada Lovelace architecture with a 5 nm process from TSMC, fitting 45,900 million transistors in a 379 mm² die. It supports DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4.

In Roblox, the GPU's role is largely to provide a high frame rate ceiling. The 716.8 GB/s memory bandwidth is overkill for a game that typically does not use heavy textures. The 16 GB of GDDR6X VRAM is also more than ample; Roblox can run on integrated graphics, so the only factor is the raw processing power of the 48.74 TFLOPS FP32 throughput. That power is evident in the 4K results: at 4K High, the combo averages 195 FPS; at 4K Medium, 221 FPS; at 4K Low, 243 FPS. The fact that the 4K Low preset still averages 243 FPS suggests that the GPU is not the bottleneck—the CPU is likely the limiting factor. The Ryzen 5 4600G has a modest single-thread score of 1919 in Cinebench R23, which is below the average of modern CPUs, but Roblox is not a heavily threaded game, and the 3.70 GHz base clock is adequate. The GPU's 76 ray tracing cores and 304 tensor cores are not used by Roblox, which relies on a simple rendering pipeline. The card's 280.6 GPixel/s pixel rate and 761.5 GTexel/s texture rate are also far above what the game can generate.

Comparing the GPU to its nearest rivals in the benchmark database, the RTX 4080 sits at the 86th percentile of all GPUs, with an average benchmark score of 54,247. Its nearest rival is the RTX 4080 SUPER, which has an average score of 54,209 (a delta of +0.1%), making the two essentially identical. Other rivals include the AMD Radeon Pro W5700X at 54,828 (-1.1%), the AMD Radeon RX 6750 GRE 12 GB. The data shows that the RTX 4080 provides a stable frame rate in Roblox, but its power is not the primary driver of performance. The CPU and the frame rate are more dependent on the game's engine.

Resolution Scaling

The frame rate drops as resolution increases, but the drop is not uniform. From 1080p to 1440p, the average FPS decreases by roughly 20% to 25% at each preset. At High settings, the 1080p average is 517 FPS and the 1440p average is 345 FPS, a drop of 172 FPS. At Medium, the 1080p average is 585 FPS and the 1440p average is 390 FPS, a drop of 195 FPS. From 1440p to 4K, the drop is more significant. At 1440p High, the average is 345 FPS; at 4K High, it is 195 FPS, a drop of 150 FPS. At 1440p Medium, it is 390 FPS; at 4K Medium, it is 221 FPS, a drop of 169 FPS. The scaling from 1080p to 4K is roughly 3x the pixel count, but the FPS does not drop by 3x. At Low settings, 1080p averages 606 FPS, 1440p averages 429 FPS, and 4K averages 243 FPS. The 4K Low frame rate is still above 240 FPS, which is a good indicator that the CPU is not the only limiting factor.

The fact that the FPS drop from 1080p to 4K is not proportional to the pixel count (which is 4x) indicates that the CPU is the limiting component. If the GPU were the bottleneck, the FPS would drop much more significantly as resolution increases. Instead, the 1080p-to-4K drop for Low settings is from 606 to 243 FPS, a factor of 2.5x. For Medium, it's from 585 to 221 FPS, a factor of 2.6x. For High, it's from 517 to 195 FPS, a factor of 2.6x. For Ultra, it's from 420 to 158 FPS, a factor of 2.6x. The consistency of this factor across settings suggests that the CPU is the primary limiter. The Ryzen 5 4600G has a 12-thread count, but Roblox is likely not using all threads. The base clock of 3.70 GHz is also modest. The result is that the user can use higher settings at 1080p without sacrificing much FPS, but the CPU will still hold the frame rate back at 4K.

The data shows that the minimum FPS at 4K Medium is 188 and the maximum is 254, which is a range of 66 FPS. At 1440p Medium, the minimum is 332 and the maximum is 449, a range of 117 FPS. At 1080p Medium, the minimum is 497 and the maximum is 673, a range of 176 FPS. The frame time variance increases at lower resolutions, which indicates that the CPU is less consistent at higher frame rates. This is a typical sign of a CPU-bound scenario, where the CPU is providing the frame but the GPU is not fully utilized.

How This Combo Ranks

The combination of the AMD Ryzen 5 4600G with the NVIDIA GeForce RTX 4080 ranks 363rd out of 3,711 combos in Roblox. This places it in the top 9.8% of all tested combinations. The 4600G is a 4000-series AMD processor with 6 cores and 12 threads, base clock 3.70 GHz, boost 4.20 GHz, and an AMD Socket AM4 mount. It has a 65W TDP and is built on the Zen 2 (Renoir) architecture. Its nearest rivals in the CPU benchmark are the AMD Ryzen 3 PRO 5355GE (average score 17,482, delta +0.1%), the AMD Ryzen 3 8300GE (17,614, -0.6%), the Intel Core 7 150U (17,395, +0.6%), and the Intel Core i3-14100T (17,648, -0.8%). The 4600G's average benchmark score is 17,507, which is nearly identical to its rivals.

The RTX 4080, as noted, is at the 86th percentile of all GPUs. The combo's rank of 363 is driven by the CPU's moderate performance. The 4600G has a single-thread score of 1,919 in Cinebench R23, which is lower than the 1,919 of the Intel rivals. But the RTX 4080 is so fast that the rank is still high. In the context of the 3,711 combos, the 4600G+RTX 4080 is in the top 10%, which is impressive for a CPU that is not a high-end part. The data shows that the 4600G is not a bottleneck in Roblox, but the 4080's raw power is not fully utilized. The rank is a reflection of the fact that the game is not demanding on the GPU.

The 4600G's integrated Vega 7 graphics are not used in this combo, but the CPU's 8 MB of L3 cache is a factor. The 6-core, 12-thread design is enough for Roblox, which typically uses a single thread or a few threads. The 3.70 GHz base clock and 4.20 GHz boost are lower than the Intel Core i7-150U, which has a delta of +0.6% in average score, but the 4600G's single-thread performance is 1,919 in Cinebench, which is a strong number. The rank of 363 means that only 362 other combos score higher. This is a high rank, but the 4600G is an APU, so the user is getting a CPU with integrated graphics that are not used, but the CPU's other features, such as the 7 nm process, are good.

• Low: average 243 FPS
• Medium: average 221 FPS, minimum 188 FPS, maximum 254 FPS
• High: average 195 FPS
• Ultra: average 158 FPS

The data shows that the 1080p Medium preset provides the best balance, with a 585 FPS average and a 497 FPS minimum. The 4K Medium preset is the only 4K setting with a minimum and maximum reported, indicating that the FPS counter recorded a range. The 4K Ultra average of 158 FPS is the lowest average across all settings. The 1440p Low preset at 429 FPS is a solid choice for users with a 1440p 144Hz monitor. The 1080p Low preset at 606 FPS is the highest average recorded, but the 21 FPS difference between Low and Medium at 1080p is not worth the visual downgrade. The 1440p Ultra preset at 280 FPS is still above 240 Hz, so it is a good option for high refresh displays. The 4K High preset at 195 FPS is above 165 Hz, and the 4K Ultra at 158 FPS is above 144 Hz. This indicates that the combo is capable of high refresh rates at all resolutions, though the CPU limits the game's frame generation.

The frame rate scaling is linear in terms of resolution. The 1080p to 4K drop is from 606 FPS to 243 FPS on Low, a factor of 2.5x. The 1080p to 1440p drop is from 606 to 429 FPS, a factor of 1.4x. The 1440p to 4K drop is from 429 to 243 FPS, a factor of 1.8x. This suggests that the CPU is the main bottleneck, as the GPU is not being fully utilized. The 4600G's 4.20 GHz boost clock is the highest clock, and the 4080's 2505 MHz boost clock is high, but the game's engine is not using the GPU's full potential. The data indicates that the user can max out the settings at 1080p without a significant FPS penalty, but the CPU will cap the frame rate around 600 FPS at 1080p.

The minimum FPS figures for Medium settings are 497 at 1080p, 332 at 1440p, and 188 at 4K. These minimums are higher than the average FPS of the Ultra preset at each respective resolution. For example, the 4K Ultra average is 158 FPS, but the 4K Medium minimum is 188 FPS. This means that Medium settings provide a higher frame rate even in the worst-case scenarios than Ultra settings provide on average. This is a strong argument for using Medium over Ultra. The 1440p Medium minimum of 332 FPS is above the 1440p High average of 345 FPS, and the 1080p Medium minimum of 497 FPS is close to the 1080p High average of 517 FPS. This shows that the Medium preset is the most consistent performer.

In summary, the data shows that this combo is a high-refresh-rate champion in Roblox. The 4600G's 6-core/12-thread design is sufficient for the game's CPU demands, and the RTX 4080's 16 GB of VRAM and 716.8 GB/s bandwidth are overkill, but the frame rates are still high. The recommended settings are Medium at any resolution, as it provides the best balance of visual quality and performance. The 4K Medium preset is the best choice for users with a 4K 144Hz monitor, and the 1080p Medium preset is best for those with a 1080p 240Hz display. The combo ranks 363rd out of 3,711, which is in the top 10% of all tested configurations. The CPU's percentile of 71 and GPU's percentile of 86 confirm that the GPU is more powerful than the CPU, but the game does not need a powerful GPU. The result is that the user can run Roblox at maximum settings with a high frame rate, limited only by the CPU's single-thread performance and the game's engine.
