Roblox

Roblox is not a demanding title by modern standards, but the data for the Intel Core i5-13400F paired with the AMD Radeon RX 580 shows a configuration that is heavily skewed toward CPU performance. Across all tested resolutions and settings, the combination delivers playable frame rates, though the margin between the processor's capability and the graphics card's output is significant. The benchmark results indicate a system where the GPU is the primary constraint, while the CPU has substantial headroom.

GPU Role

The AMD Radeon RX 580 is the definitive bottleneck in this configuration for Roblox. The GPU's architecture is GCN 4.0, built on a 14 nm process, and it carries a transistor count of 5,700 million. With 2,304 shading units and 32 ROPs, the card posts a pixel rate of 42.88 GPixel/s and a texture rate of 193.0 GTexel/s. The FP32 performance is rated at 6.175 TFLOPS. These specifications align with its 53rd percentile ranking among all GPUs, indicating a mid-range part that is now several generations old.

The memory configuration is a key factor in resolution scaling. The 8 GB of GDDR5 is paired with a 256-bit bus, yielding 256.0 GB/s of bandwidth. This is sufficient for 1080p gameplay but becomes a limiting factor as resolution increases. The base clock is 1257 MHz, with a boost clock of 1340 MHz, and the memory runs at an effective 8 Gbps. In the measured results, the GPU's influence is clear: at 1080p Low settings, the system reaches 167 FPS, which drops to 106.5 FPS at Ultra. The spread between Low and Ultra at 1080p is 60.5 FPS, showing that the GPU is sensitive to shader complexity and fill-rate demands.

At 4K, the GPU's limitations become pronounced. The average frame rate at 3840x2160 Ultra is 40.9 FPS, which is barely playable, while dropping to Low settings recovers to 62.2 FPS. The RX 580's nearest rivals in the benchmark database include the NVIDIA GeForce GTX 570, which scores 0% differently, and the GTX 950, which scores 0.1% higher. This places the RX 580 in a performance class that is adequate for esports and light sandbox games, but it lacks the raw throughput for high-fidelity 4K rendering. The data shows that the GPU's DirectX 12 benchmark score is 43, while its DirectX 11 score is 60, suggesting that older API paths are more efficient on this architecture.

CPU Role

The Intel Core i5-13400F is a significantly stronger component than the GPU in this pairing. It features 10 cores and 16 threads, with a base clock of 2.50 GHz and a boost clock of 4.60 GHz. The processor is built on Intel's 10 nm process and uses the Raptor Lake architecture. Its 20 MB of shared L3 cache is a substantial resource for game logic and physics calculations. The CPU's percentile ranking is 82, which is notably higher than the GPU's 53rd percentile, confirming that the processor is not the limiting factor in Roblox.

Benchmark data for the CPU shows strong multi-threaded performance: Cinebench R23 multi-core scores 21,279, and Geekbench multi-core scores 10,971. Single-thread performance is also solid, with Cinebench R23 single-core at 3,004 and Passmark single-thread at 3,634. These scores indicate that the CPU can handle the single-threaded nature of Roblox's main game loop with ease. The nearest rivals for the CPU include the Intel Core i7-13620H, which is 0.1% faster on average, and the AMD Ryzen 5 5600X3D, which is 0.5% faster. This level of performance means that in Roblox, the CPU is likely delivering frame times that are far lower than what the GPU can render.

The CPU's ability to maintain high frame rates is evident in the 1080p Low setting result of 167 FPS. At this setting, the GPU is less burdened, and the CPU's single-thread strength allows the system to push toward the upper limits of what the RX 580 can output. The 3DMark single-thread score of 960 and the 2-thread score of 1,880 are relevant here, as Roblox typically relies on a few heavily loaded threads. The CPU's Passmark physics score of 1,437 further supports its capability in game logic. In this configuration, the CPU is operating well below its maximum capacity, providing a buffer that prevents frame drops in complex sandbox scenarios.

How This Combo Ranks

The combination of the Intel Core i5-13400F and the AMD Radeon RX 580 ranks 1667 out of 1800 tested combos in Roblox. This places the pairing in the bottom 7.4% of all tested configurations, which is a surprising result given the individual components' specifications. The data suggests that this ranking is dragged down almost entirely by the GPU, as the CPU alone ranks in the 82nd percentile, while the GPU ranks in the 53rd percentile. The disparity between the two components creates an imbalanced system where the GPU cannot fully utilize the CPU's potential.

In practical terms, this ranking means that most other tested combinations—even those with older or weaker CPUs—will outperform this setup if they have a stronger GPU. The combo's rank is not a reflection of poor optimization but rather a clear indication of the GPU's age and performance ceiling. For Roblox, which is a lightweight title, the GPU's 8 GB of VRAM and 256.0 GB/s bandwidth are sufficient for most scenes, but the compute throughput of 6.175 TFLOPS limits the overall frame rate. The CPU's 16 threads and 4.60 GHz boost clock are far more capable than what this game requires, making the combo's rank a direct consequence of the GPU's 53rd percentile standing.

The benchmark results confirm this imbalance. At 1080p High, the combo achieves 131.3 FPS, which is respectable but not exceptional compared to other systems that might feature a newer mid-range GPU. The ranking of 1667 indicates that there are 133 other tested combos that perform worse, likely involving older or entry-level GPUs. However, the fact that the CPU is in the top 18% of all processors while the combo ranks in the bottom 10% underscores the extent to which the GPU is the binding constraint in this pairing.

Resolution Scaling

The resolution scaling data reveals a classic GPU-bound pattern. At 1920x1080, the average frame rates range from 167 FPS at Low settings to 106.5 FPS at Ultra. Moving to 2560x1440, the same settings yield 108.5 FPS and 73.1 FPS, respectively. At 3840x2160, the numbers drop further to 62.2 FPS at Low and 40.9 FPS at Ultra. The percentage drop from 1080p to 4K is substantial: at High settings, the frame rate falls from 131.3 to 52 FPS, a 60.4% reduction. At Low settings, the drop is from 167 to 62.2 FPS, a 62.7% reduction.

This consistent decline across all settings indicates that the limiting component is the GPU. If the CPU were the bottleneck, the frame rates would remain relatively flat as resolution increases, because the CPU workload would stay constant while the GPU workload scales with pixel count. The data shows the opposite: frame rates fall proportionally with the increase in resolution, which is the signature of a GPU-limited system. The RX 580's memory bandwidth of 256.0 GB/s and its 32 ROPs are simply not sufficient to sustain high throughput at 4K resolutions.

The scaling from 1440p to 4K is particularly steep. At Medium settings, the frame rate goes from 100.3 FPS at 2560x1440 to 57.8 FPS at 3840x2160. This 42.4% drop is nearly identical to the 40.9% drop observed at High settings (89.4 to 52 FPS). The uniformity of these percentage drops across different quality presets suggests that the GPU is hitting a hard limit on pixel throughput rather than a memory bandwidth ceiling. The CPU, with its high single-thread score of 3,004 in Cinebench R23, has ample headroom to feed the GPU at all resolutions, but it is never given the chance to become the limiting factor. The conclusion from the data is that users seeking higher frame rates at 4K would need to upgrade the GPU, while the CPU could remain unchanged without any loss in performance.
