Roblox

The Intel Core i5-13400F paired with the AMD Radeon RX 6600 delivers a remarkably consistent experience in Roblox, with the data showing that the CPU is the primary limiting factor at lower resolutions. The combination ranks in the 1435th position out of 1800 tested combos, placing it in the 21st percentile of all systems tested for this title. The measured FPS data reveals that this system is capable of pushing well beyond the refresh rates of most standard monitors, though the scaling pattern between resolutions and settings indicates where the performance ceiling truly lies.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but not catastrophic, revealing a system that transitions from being CPU-bound to GPU-bound as resolution increases. At 1080p with Ultra settings, the system produces 184.2 FPS, while at 4K Ultra it falls to 70.3 FPS—a 61.8% reduction in frame rate. This scaling pattern is typical of a system where the processor has significant headroom at lower resolutions, allowing the GPU to work harder as pixel count rises.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the difference between Low (283.2 FPS) and Ultra (184.2 FPS) is 99 FPS, while at 4K the same comparison shows only a 36.1 FPS gap (106.4 vs 70.3). This compression of performance at 4K indicates that the Radeon RX 6600 becomes the bottleneck when pixel count increases, while at 1080p the Core i5-13400F's strong single-thread performance keeps frame rates high regardless of settings. The 1440p results sit squarely in between, with Ultra delivering 120.8 FPS and Low reaching 189.2 FPS, confirming a smooth transition in the limiting component.

How This Combo Ranks

The combo rank of 1435 out of 1800 tested systems places this configuration in the lower-middle tier of all tested combinations for Roblox, despite delivering playable frame rates at every resolution and setting tested. The data shows that this ranking is more a reflection of the competitive field than a deficiency in absolute performance—many systems in the database feature higher-end GPUs or newer processors. The Core i5-13400F holds an 82nd percentile ranking among all CPUs tested, while the Radeon RX 6600 sits at the 69th percentile among GPUs, suggesting the combination is well-balanced relative to their respective component pools.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates across all settings. Low settings produce 283.2 FPS, Medium reaches 256.1 FPS, High achieves 224.2 FPS, and Ultra settles at 184.2 FPS. The progression between presets is linear, with each step from Low to Ultra reducing frame rate by roughly 15-20%. This suggests the CPU has ample headroom to feed the GPU at this resolution, as even the most demanding preset remains well above 144 FPS.

Moving to 2560x1440, performance remains strong but shows the GPU beginning to exert more influence. Low settings produce 189.2 FPS, Medium delivers 171.5 FPS, High reaches 153 FPS, and Ultra drops to 120.8 FPS. The percentage drop from 1080p to 1440p is relatively uniform across settings, averaging around 30%, which indicates a balanced scaling where both components contribute to the performance profile.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings deliver 106.4 FPS, Medium achieves 98.1 FPS, High produces 84.1 FPS, and Ultra falls to 70.3 FPS. The 4K results show a compressed range of only 36.1 FPS between Low and Ultra, compared to 99 FPS at 1080p. This compression is characteristic of a GPU-limited scenario where the RX 6600's 8 GB of GDDR6 memory and 224.0 GB/s bandwidth become the primary constraints, rather than the processor's ability to feed frames.

GPU Role

The AMD Radeon RX 6600's specifications directly explain its performance profile in Roblox. The GPU features 8 GB of GDDR6 memory on a 128-bit bus with 224.0 GB/s bandwidth, which is sufficient for the game's moderate texture requirements at 4K. The boost clock of 2491 MHz and game clock of 2044 MHz provide ample compute throughput, with the GPU delivering 8.928 TFLOPS of FP32 performance. These specifications place the card in the 69th percentile among all GPUs tested, with a PassMark G3D score of 15096.

The 4K Ultra result of 70.3 FPS represents the GPU's practical limit in this title, and the 28 ray tracing cores and 1792 shading units contribute to rendering performance but are not heavily utilized in Roblox's art style. The GPU's average benchmark score of 25235 puts it nearly identical to the AMD Radeon 890M (0% delta) and within 0.5% of the NVIDIA GeForce RTX 3060 Ti, indicating that the RX 6600's performance tier is well-established. The 7 nm process node and 11,060 million transistors suggest efficient power delivery, though the 132 W TDP means the card requires adequate cooling to maintain boost clocks during extended sessions.

Settings Recommendations

For users with 1080p displays, the High preset at 224.2 FPS provides the best experience, offering near-maximum visual quality while still delivering frame rates that exceed virtually all gaming monitors' refresh rates. The Ultra preset at 184.2 FPS is also viable for those prioritizing visual fidelity, as the 40 FPS difference between High and Ultra is unlikely to be perceptible on standard 144 Hz displays. At 1440p, the High preset at 153 FPS is the optimal choice, balancing quality with the headroom needed for smooth gameplay on high refresh rate monitors.

For 4K displays, the Medium preset at 98.1 FPS offers the best compromise between visual quality and performance, as the jump from Medium to High costs 14 FPS (98.1 to 84.1) while delivering only marginal visual improvements. The Low preset at 106.4 FPS is recommended for users who prioritize frame rate above all else, though the visual trade-offs may be noticeable in Roblox's blocky aesthetic. The Ultra preset at 70.3 FPS is playable but falls below the 75 Hz threshold that some 4K monitors support, making it less ideal for motion-sensitive gameplay.

CPU Role

The Intel Core i5-13400F demonstrates that a 10-core, 16-thread processor with a 2.50 GHz base clock and 4.60 GHz boost clock is more than sufficient for Roblox. The CPU's benchmark results show strong single-thread performance, with a 3DMark single-thread score of 960 and a Geekbench single-core score of 2301, which directly translates to the high frame rates observed at 1080p. The 20 MB of shared L3 cache provides fast access to frequently used game data, while the 10 nm Raptor Lake architecture with 16 threads ensures smooth handling of background tasks without impacting game performance.

The processor's 82nd percentile ranking among all CPUs, with an average benchmark score of 25236, indicates it sits in the upper tier for gaming workloads. Its Cinebench R23 multicore score of 21279 and PassMark multithread score of 25032 show that even in CPU-bound scenarios, the i5-13400F has significant headroom. The 1080p results, where frame rates remain above 184 FPS even at Ultra settings, confirm that the CPU is rarely the limiting factor in Roblox. The 4K results, which show a compressed performance range across settings, further prove that the GPU—not the CPU—constrains performance at higher resolutions. The processor's 65 W TDP and support for DDR4 and DDR5 memory make it a versatile choice, though the data indicates that its single-thread capabilities are the primary driver of Roblox's responsiveness.
