Roblox

Roblox is a sandbox title that scales across a very wide range of hardware, and the combination of an AMD Ryzen 5 3600 with an AMD Radeon RX 9070 produces a dataset that is heavily weighted toward the graphics card. The Ryzen 5 3600 is a 6-core, 12-thread processor from the 3000 series, built on the Zen 2 architecture with a base clock of 3.60 GHz and a boost clock of 4.20 GHz. It carries 32 MB of shared L3 cache and supports DDR4 memory in a dual-channel configuration. Its benchmark profile shows a multi-thread score of 15045 in Cinebench R23 and a single-core score of 2124 in the same test, placing it in the 71st percentile among all tested CPUs. The RX 9070, by contrast, is a Radeon RX 9000 series part based on RDNA 4.0, using the Navi 48 chip on a 4 nm process. It has 16 GB of GDDR6 memory on a 256-bit bus, with a boost clock of 2520 MHz and a game clock of 2070 MHz. The GPU’s PassMark G3D score is 25381, which puts it in the 69th percentile among all GPUs. In this specific game, the measured frames per second (FPS) show that the RX 9070 is rarely the limiting factor, even at 4K, which makes the CPU’s role in delivering those frames the more interesting part of the analysis.

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

The Ryzen 5 3600 provides six physical cores and twelve threads, which is a configuration that has been a common baseline for gaming PCs since its release in 2019. For a game like Roblox, which is not known for heavy multi-threaded workloads, the single-thread performance often matters more than the raw core count. The CPU’s single-thread scores reflect this: it achieves 696 in 3DMark single-thread, 892 in Cinebench R20 single-core, and 2124 in Cinebench R23 single-core. These numbers are modest compared to modern high-end parts, but they are sufficient to drive very high frame rates in this title, as the measured data shows. The boost clock of 4.20 GHz is the maximum frequency the chip can reach, and in a game that is not heavily threaded, that frequency is likely the deciding factor for CPU-bound scenarios.

Looking at the benchmark results, the Ryzen 5 3600’s multi-threaded capabilities are far from weak. It scores 4605 in 3DMark with 16 threads and 4603 with max threads, which is nearly identical, indicating that the extra threads beyond 16 do not add much for this workload. The PassMark multi-thread score of 17700 and the Geekbench multi-core score of 7372 reinforce that this is a competent 6-core part. However, in Roblox, the game’s engine typically relies on one or two primary threads for simulation and rendering commands. The 2-thread 3DMark score of 1361 and the 4-thread score of 2579 are more relevant to how the CPU handles the game’s main loop. The single-thread 3DMark score of 696 is the lowest of the group, which suggests that in a scenario where the GPU is not the bottleneck, the CPU’s single-core speed will cap the FPS.

The data supports this interpretation. At 1080p with Low settings, the average FPS is 474, which is extremely high. At the same resolution with Medium settings, it drops to 431, and at High it is 381. The difference between Low and High at 1080p is about 93 FPS, which indicates that the GPU is still doing meaningful work, but the absolute numbers are so high that the CPU must be keeping up with the render thread. The fact that the CPU’s percentile versus all CPUs is 71 means it is better than 71% of tested processors, but in a game where frame rates exceed 300 FPS, the limiting factor is often the game’s own engine logic or the CPU’s single-thread speed. The Ryzen 5 3600’s boost clock of 4.20 GHz is not exceptional by 2025 standards, but it is enough to push well past 300 FPS in this title at lower settings.

How This Combo Ranks — use comboRankInGame vs other tested combos

The combination of the Ryzen 5 3600 and the RX 9070 has a recorded rank of 1122 out of 3711 tested combos in Roblox. This places it in the top 30% of all configurations that have been benchmarked for this game. That rank is notable because the RX 9070 is a very powerful GPU, but the CPU is older and less capable than many modern processors. The data suggests that the combo is not limited by the GPU in most scenarios, which means the rank is likely determined by how well the CPU can feed the GPU. If the CPU were a higher-end part, the rank would probably be higher, but the Ryzen 5 3600’s single-thread performance holds it back from the very top positions.

To put the CPU’s contribution in context, its nearest rivals in average benchmark score include the Intel Core i7-1260P (0.2% ahead), the Intel Core i5-11400 (0.2% behind), and two AMD EPYC server chips that are within 0.2% of its score. These deltas are tiny, meaning the Ryzen 5 3600 is essentially tied with those parts in general processing power. However, in a game like Roblox, the specific behavior of the CPU’s cores matters more than aggregate scores. The i5-11400, for example, has a similar core count but different clock behavior, which could produce different FPS numbers in CPU-bound scenarios. The data does not include those rivals’ FPS in Roblox, so a direct comparison is not possible, but the combo rank of 1122 out of 3711 gives a clear picture: this is a solid mid-to-high-tier pairing, not a top-tier one.

The rank also implies that there are 2589 combos that perform worse and 1121 that perform better. Given the RX 9070’s capabilities, most of those better-performing combos likely use newer CPUs with higher single-thread speeds. The Ryzen 5 3600’s launch MSRP was $199, but that is not relevant to its performance rank. What matters is that the combo’s rank is respectable, and the FPS numbers confirm that it delivers a highly playable experience in Roblox.

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

The measured FPS data shows a clear progression as resolution increases, and the pattern reveals which component is the bottleneck at each step. At 1080p, the average FPS for Low settings is 474, but at 1440p it is 316, and at 4K it is 179. That is a drop of 158 FPS from 1080p to 1440p, and another 137 FPS from 1440p to 4K. The scaling is not linear; the percentage drop from 1080p to 1440p is about 33%, while the drop from 1440p to 4K is about 43% (relative to the 1440p value). This suggests that the GPU is becoming more of a limiting factor as resolution climbs, but even at 4K, the average FPS of 179 is far above the typical 60 FPS target.

Look at the Medium settings data, which includes min and max FPS values. At 1080p Medium, the average is 431 with a min of 367 and a max of 496. At 1440p Medium, the average drops to 288 with a min of 245 and a max of 331. At 4K Medium, the average is 163 with a min of 138 and a max of 187. The min-to-max spread narrows as resolution increases, which is typical because the GPU’s frame time becomes more consistent when it is the bottleneck. At 1080p, the spread is 129 FPS (367 to 496), which is large and indicates that the CPU is causing frame time variance. At 4K, the spread is 49 FPS (138 to 187), showing that the GPU is producing more uniform frames.

This pattern is a classic sign of a CPU-bound scenario at lower resolutions. The Ryzen 5 3600 can render the game’s logic fast enough to produce over 400 FPS, but it cannot maintain a perfectly steady frame rate because the game’s main thread has occasional hitches. As the resolution increases, the GPU takes over as the primary limiter, and the frame rate becomes smoother relative to the average. The fact that 4K Low (179 FPS) is lower than 1440p Low (316 FPS) by 137 FPS confirms that the GPU is doing significantly more work at 4K, but the RX 9070 has enough horsepower to keep the experience fluid.

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

The full dataset provides twelve measured points, four settings at each of three resolutions. At 1920x1080, the Low preset yields an average of 474 FPS, Medium yields 431 FPS (with a min of 367 and max of 496), High yields 381 FPS, and Ultra yields 309 FPS. The step from Low to Ultra is 165 FPS, which is a 35% reduction in performance. This shows that the Ultra preset is substantially more demanding, likely due to increased draw distances, shadow quality, and post-processing effects. The Medium preset’s min FPS of 367 is still above the refresh rate of most high-end monitors, meaning that even the lowest frames are very playable.

Moving to 2560x1440, the averages are 316 FPS for Low, 288 FPS for Medium (min 245, max 331), 254 FPS for High, and 206 FPS for Ultra. The drop from 1080p to 1440p is consistent across settings: Low falls by 158 FPS, Medium by 143 FPS, High by 127 FPS, and Ultra by 103 FPS. The absolute differences shrink as settings increase, which indicates that the GPU’s workload at Ultra is already high at 1440p, so the resolution increase has a smaller relative impact. The Medium min FPS of 245 at 1440p is still comfortably above 144 Hz, which is the target for most gaming monitors.

At 3840x2160, the averages are 179 FPS for Low, 163 FPS for Medium (min 138, max 187), 144 FPS for High, and 117 FPS for Ultra. The drop from 1440p to 4K is 137 FPS for Low, 125 FPS for Medium, 110 FPS for High, and 89 FPS for Ultra. The Ultra preset at 4K is the only configuration that falls below 120 FPS, with an average of 117 FPS. The Medium preset at 4K still has a min FPS of 138, which is above 120 Hz, so even the minimum frames are high. The data shows that this combo can handle Roblox at 4K with High settings at 144 FPS average, which is impressive given the CPU’s age.

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

The AMD Radeon RX 9070 is the dominant component in this pairing, and its specifications explain why it can deliver such high frame rates. It has 16 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 644.6 GB/s. For a game like Roblox, which is not known for massive texture packs or high VRAM usage, 16 GB is more than sufficient, even at 4K Ultra. The memory clock is 2518 MHz, which translates to 20.1 Gbps effective, and the GPU’s boost clock is 2520 MHz. The shading units number 3584, with 224 texture mapping units and 128 render output units. The pixel rate is 322.6 GPixel/s, and the texture rate is 564.5 GTexel/s. These numbers are all extremely high, and they allow the GPU to process the game’s simple geometry and lighting quickly.

The GPU’s benchmark scores reflect its power. It scores 6290 in 3DMark Steel Nomad DX12, 25381 in PassMark G3D, and 14737 in PassMark GPU Compute. Its Geekbench OpenCL score is 131539, and Vulkan score is 58705. The nearest rivals in average benchmark score are the NVIDIA GeForce GTX TITAN Z (0.6% ahead), the AMD Radeon RX 6800S (0.8% behind), the NVIDIA GeForce RTX 3080 Mobile (1.1% ahead), and the NVIDIA GeForce RTX 2080 SUPER (1.2% behind). These deltas are small, meaning the RX 9070 performs similarly to those GPUs in aggregate benchmarks, but in Roblox, the specific driver optimizations and the game’s engine can produce different results. The GPU’s percentile versus all GPUs is 69, which is lower than the CPU’s 71, but that is because there are many more GPUs in the database that are newer and faster.

In the measured FPS data, the GPU’s role is evident in how the frame rate scales with settings. At 4K, the difference between Low and Ultra is 62 FPS (179 vs 117), which is a 35% drop. This is a smaller percentage drop than at 1080p, where Low to Ultra is a 35% drop as well (474 to 309). The consistency of that percentage across resolutions suggests that the GPU is handling the increased load from Ultra settings in a linear fashion, with no signs of VRAM or bandwidth limitations. The 16 GB VRAM is never a constraint in Roblox, so the GPU can focus entirely on rendering the scene.

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

Based on the measured FPS data, the best experience depends on the target resolution and refresh rate, but the Medium preset stands out as the most balanced option across all three resolutions. At 1080p, Medium delivers 431 FPS average with a minimum of 367 FPS, which exceeds the refresh rate of any consumer monitor on the market. The High preset at 381 FPS is also excellent, but the jump from Medium to High costs 50 FPS for visual improvements that are likely marginal in a sandbox game. At 1440p, Medium yields 288 FPS average with a min of 245 FPS, which is still far above 144 Hz. High at 254 FPS is also viable, but Medium provides a larger safety margin for frame drops.

At 4K, the choice becomes more nuanced. Medium produces 163 FPS average with a min of 138 FPS, which is just above the 120 Hz threshold for high-refresh monitors. High drops to 144 FPS average, and Ultra falls to 117 FPS average, which is below 120 Hz. For 4K users with a 144 Hz monitor, Medium is the recommended preset because it maintains a minimum FPS above 138, ensuring no dips below the refresh rate. For 4K users with a 60 Hz or 120 Hz monitor, High at 144 FPS average is also a good choice, but the min FPS data is not available for High, so Medium is the safer pick based on the recorded numbers.

The Low preset is not recommended for any resolution because it sacrifices visual quality for frame rates that are already excessive at Medium. At 1080p Low, 474 FPS is overkill, and at 4K Low, 179 FPS is still higher than what most monitors can display. The Ultra preset is only worth considering at 1080p, where 309 FPS average is still very high, but at 1440p and 4K, the frame rate drops to 206 and 117, respectively, which makes it less attractive. Overall, the Medium preset at each resolution provides the best combination of high average FPS, a solid minimum FPS floor, and reasonable visual quality.
