Roblox

Roblox is a long-running sandbox title that scales across a wide range of hardware, and the pairing of the AMD Ryzen 5 5500 with the AMD Radeon RX 9070 produces a dataset that clearly separates CPU-bound and GPU-bound regimes. The measured frames per second (FPS) across three resolutions and four quality presets show a system that is rarely stressed at 1080p, becomes more balanced at 1440p, and finally shifts toward the graphics card at 4K. This analysis breaks down those results, using only the provided benchmark data to explain where the bottleneck sits and how this combo ranks among 1,800 tested configurations.

Resolution Scaling

The FPS drop from 1080p to 4K is steep but predictable, and the magnitude of that drop depends heavily on the quality preset. At Low settings, the average frame rate falls from 474.8 FPS at 1920x1080 to 317.8 FPS at 2560x1440, then to 177.8 FPS at 3840x2160. That represents a 62.6% reduction from 1080p to 4K, indicating that the GPU is taking on more work as pixel count rises. At Ultra settings, the same resolution sweep goes from 310.2 FPS at 1080p to 209.1 FPS at 1440p, and finally to 116.3 FPS at 4K — a 62.5% cut. Notably, the percentage drop is nearly identical across Low and Ultra, which suggests that the game’s rendering load scales uniformly with resolution rather than being disproportionately affected by texture or shading complexity.

The gap between Low and Ultra also widens with resolution. At 1080p, the difference between Low (474.8 FPS) and Ultra (310.2 FPS) is 164.6 FPS. At 4K, that gap narrows to 61.5 FPS (177.8 vs. 116.3). This pattern is classic GPU-limiting behavior: when the GPU is idle at lower resolutions, the CPU can push very high frame rates, but the quality preset still matters because it alters the GPU’s per-frame workload. At 4K, the GPU becomes the primary limiter, so raising settings from Low to Ultra costs a smaller absolute FPS amount — the card is already saturated. Benchmark results indicate that the RX 9070, with its 16 GB of GDDR6 memory and 644.6 GB/s bandwidth, is the component that determines the ceiling at 3840x2160, while the Ryzen 5 5500’s six cores and 12 threads are sufficient to keep up at lower resolutions.

CPU Role

The Ryzen 5 5500 is a Zen 3 part on the AMD Socket AM4 platform, built on TSMC’s 7 nm process. It runs at a base clock of 3.60 GHz and a boost clock of 4.20 GHz, with 6 cores and 12 threads. Its cache hierarchy includes 64 KB of L1 per core, 512 KB of L2 per core, and 16 MB of L3. In synthetic tests, the CPU scores 836 in 3dmark single-thread and 5,411 in 3dmark max threads, while Cinebench R23 results show 2,319 in single-core and 16,429 in multi-core. These numbers place it in the 79th percentile among all CPUs, with an average benchmark score of 20,875.

In Roblox, the CPU’s role becomes evident when looking at the 1080p Low result: 474.8 FPS. That figure is far above what most games would produce, and it indicates that the CPU is feeding the GPU with enough draw calls and physics updates to sustain very high frame rates. However, the fact that 1080p Ultra (310.2 FPS) is lower than 1080p Low (474.8 FPS) shows that the GPU’s settings still influence the outcome even at a resolution where the CPU has headroom. The Ryzen 5 5500’s single-thread performance, reflected in its 836 3dmark single-thread score, is adequate for Roblox’s typically light per-core load, but the game does not appear to scale beyond a few threads — the 12-thread count is not a limiting factor here. Compared to its nearest rival, the Intel Core i5-12500, the Ryzen 5 5500 is essentially tied, with a deltaPct of -0.1% in average benchmark score. This means the CPU is not a differentiator in this combo; its performance is typical for the class.

GPU Role

The Radeon RX 9070 is the dominant component in this pairing. It is built on RDNA 4.0 architecture with a Navi 48 chip, fabricated on TSMC’s 4 nm process with 53,900 million transistors. The GPU has 3,584 shading units, 224 texture mapping units, and 128 render output units, with a boost clock of 2520 MHz and a game clock of 2070 MHz. Its memory subsystem consists of 16 GB of GDDR6 on a 256-bit bus, delivering 644.6 GB/s of bandwidth. The card’s compute capability is rated at 36.13 TFLOPS FP32, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4.

In Roblox, the GPU’s influence is most visible at 4K. At 3840x2160, the average FPS ranges from 177.8 at Low to 116.3 at Ultra, a spread of 61.5 FPS. This is a narrower range than at 1080p (where the spread is 164.6 FPS) because the GPU is already working harder at 4K, so the difference between presets is compressed. The RX 9070’s 16 GB VRAM is unlikely to be a constraint in Roblox, which is not a memory-heavy title, but the card’s raw throughput determines the 4K ceiling. The GPU’s average benchmark score of 34,780 and its 79th percentile ranking among all GPUs put it in the upper midrange. Its nearest rivals include the NVIDIA A2 (deltaPct -0.2%) and the Quadro GV100 (deltaPct 0.3%), which are not gaming-focused cards, indicating that the RX 9070’s synthetic scores are competitive but not class-leading. In practice, the measured FPS shows that the GPU is the limiting factor at 4K Ultra, where the 116.3 FPS average is still very playable but represents a clear drop from the 310.2 FPS at 1080p Ultra.

Measured FPS Breakdown

The dataset provides 12 measured points, covering four settings (Low, Medium, High, Ultra) at three resolutions (1920x1080, 2560x1440, 3840x2160). At 1080p, the average FPS values are: Low 474.8, Medium 428.3, High 382.9, and Ultra 310.2. The step from Low to Medium is 46.5 FPS, Medium to High is 45.4 FPS, and High to Ultra is 72.7 FPS — the largest single drop occurs when moving to Ultra, suggesting that preset includes effects like shadows or reflections that heavily tax the GPU even at this resolution.

At 2560x1440, the results are: Low 317.8, Medium 291.1, High 256.2, and Ultra 209.1. The percentage reduction from 1080p to 1440p is consistent: Low drops by 33.1%, Medium by 32.0%, High by 33.1%, and Ultra by 32.6%. This uniformity indicates that the game’s rendering pipeline scales linearly with pixel count, with no sudden bottlenecks appearing at 1440p. The 1440p Ultra result of 209.1 FPS is still well above 144 Hz, making this combo suitable for high-refresh monitors at that resolution.

At 4K, the numbers are: Low 177.8, Medium 163.6, High 142.6, and Ultra 116.3. The gap between Low and Medium is 14.2 FPS, Medium to High is 21.0 FPS, and High to Ultra is 26.3 FPS. Here, each quality step costs more FPS than the previous one, which is the opposite of the 1080p pattern. This indicates that at 4K, the GPU is the bottleneck, and each additional rendering feature (such as higher texture filtering or more complex geometry) directly reduces throughput. The 4K Ultra result of 116.3 FPS is still above 60 FPS, so the combo remains playable, but it is clearly not a 4K 240Hz setup.

How This Combo Ranks

The combination of the Ryzen 5 5500 and the RX 9070 ranks 584th out of 1,800 tested combos in Roblox. That places it in the 67.6th percentile of all configurations, meaning roughly one-third of tested systems perform better. This rank is somewhat surprising given the GPU’s capability, but it reflects the fact that Roblox is not a demanding title — many older or more modest GPUs can achieve high FPS, and the ranking is determined by the absolute average FPS across all tested settings. The RX 9070’s 16 GB VRAM and 644.6 GB/s bandwidth are overkill for Roblox, but they don’t hurt; the GPU simply doesn’t have enough work to do at 1080p and 1440p to separate itself from cheaper cards.

The rank also highlights the CPU’s role. The Ryzen 5 5500’s average benchmark score of 20,875 is within 0.1% of the Intel Core i5-12500 and the AMD Ryzen 5 PRO 4655GE, meaning the CPU is not a performance outlier. In a game like Roblox, where the workload is light and often single-threaded, the 5500’s 3,058 Passmark single-thread score is sufficient, but it doesn’t push the combo higher in the rankings. The measured FPS data shows that the system is never CPU-limited in a way that would cause stutters — even at 1080p Low, 474.8 FPS indicates the CPU can feed frames far faster than the GPU can render them. However, the combo rank of 584 out of 1,800 suggests that many other pairings, likely with higher-clocked CPUs or more powerful GPUs, achieve even higher averages. The data indicates that this is a balanced mid-range setup that excels at 1440p and handles 4K well, but it does not top the charts in Roblox due to the game’s low overall demands.
