The final rank of 2322/3010 suggests that this pairing offers a very smooth and enjoyable experience, with the potential to hit very high refresh rates at lower resolutions and maintain playable, if not maxed-out, frame rates at 4K.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the user's display resolution and refresh rate goals. The data shows that the system is capable of exceeding 144 FPS at both 1080p and 1440p on most presets, making it an excellent match for high-refresh-rate monitors.

For 1920x1080 displays, the High preset, which averages 226 FPS, provides an excellent balance between visual fidelity and performance. While the Low preset pushes the average to an impressive 281 FPS, the visual quality compromise is likely unnecessary for most users, as even the Ultra preset maintains an average of 184 FPS, which is well above the 144 Hz threshold. For users with a 240 Hz monitor, the Medium preset at 256 FPS offers a better visual experience than Low while still providing frame rates high enough to take advantage of such a display.

At 2560x1440, the High preset is again the sweet spot, with an average of 151 FPS. This is perfect for a 144 Hz monitor. The Ultra preset drops to 123 FPS, which is still playable but may not be ideal for competitive play. The Medium preset at 171 FPS offers a good alternative for those who want a little more headroom above 144 Hz. For a 4K (3840x2160) display, the choice is more constrained. The Ultra preset averages 69 FPS, which is suitable for 60 Hz displays and visually rich single-player experiences. The High preset at 85 FPS is a better option for those seeking a smoother experience, while the Medium preset at 97 FPS provides the best balance of quality and performance for 4K gaming, ensuring a consistently fluid feel.

Measured FPS Breakdown

The measured data provides a clear picture of how the system scales across different graphical loads. At 1920x1080, the system is clearly CPU-bound. The average frame rates are exceptionally high, starting at 281 FPS on Low and only dropping to 184 FPS on Ultra. The Medium preset reports an average of 256 FPS with a minimum of 218 FPS and a maximum of 294 FPS, showing very consistent performance. This 97 FPS spread between Low and Ultra at 1080p suggests that the CPU is able to feed frames faster than the GPU can render them at this resolution, making the GPU the limiting factor even at Low settings.

Moving to 2560x1440, the resolution increase begins to put more strain on the GPU. The average frame rates remain high, with Low at 188 FPS, Medium at 171 FPS (min 145, max 197), High at 151 FPS, and Ultra at 123 FPS. The gap between Low and Ultra has widened to 65 FPS, indicating a growing GPU workload. However, the system still delivers well over 120 FPS on all presets, making it a superb performer for high-refresh-rate 1440p gaming.

At 3840x2160, the GPU becomes the definitive bottleneck. The average frame rates drop significantly, with Low at 106 FPS, Medium at 97 FPS (min 82, max 111), High at 85 FPS, and Ultra at 69 FPS. The spread between Low and Ultra is now 37 FPS, which is smaller in absolute terms but represents a larger percentage drop from the Low preset. This pattern clearly shows that the Radeon RX 6600's rendering capabilities are being maxed out at 4K, and the CPU's performance headroom is no longer the primary constraint.

GPU Role

The AMD Radeon RX 6600, with its 8 GB of GDDR6 memory on a 128-bit bus, provides a bandwidth of 224.0 GB/s. This memory configuration is sufficient for Roblox at 1080p and 1440p, as evidenced by the high frame rates. However, at 4K, the demands on memory bandwidth and the GPU's compute units (1792 shading units) become much more significant. The GPU's boost clock of 2491 MHz and game clock of 2044 MHz allow it to perform well, but the 4K Ultra results of 69 FPS show its limits.

The GPU's performance relative to its peers is tightly clustered. Its average benchmark score of 19036 is virtually tied with competitors like the NVIDIA Quadro K6000 (0% delta) and the NVIDIA GeForce RTX 4050 Mobile (-0.1% delta). This indicates that while the RX 6600 is not a top-tier card, it is a dependable mid-range performer. In Roblox, this translates to a card that can handle the game's stylized graphics with ease at mainstream resolutions but will require a reduction in settings to maintain high refresh rates at 4K.

The fact that the RX 6600 is an end-of-life product with a successor (Navi III) already available doesn't diminish its current capabilities in this title. The data shows it is more than capable of delivering a great experience, particularly when paired with a powerful CPU like the Core Ultra 5 225. The 8 GB of VRAM is a key asset, as it likely prevents any texture-related stuttering even at 4K Ultra, where the average FPS, while lower, remains playable.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake architecture. Its base clock of 3.30 GHz and boost clock of 4.90 GHz are crucial for Roblox, which often relies on a few heavily utilized threads. The CPU's PassMark single-thread score of 4412 is exceptionally high, which is a primary reason why the system achieves over 180 FPS even at 4K with Low settings. This indicates the CPU is rarely the limiting factor in this configuration.

The processor's multi-threaded capabilities, with a Cinebench R23 multi-core score of 25891, are also robust. This ensures that background tasks and the game's physics engine, which can use multiple threads, do not cause frame drops. The 20 MB of shared L3 cache helps keep data readily accessible for the cores, further improving performance. In the context of Roblox, which can have complex user-built environments, this cache and core configuration help maintain consistent frame times.

Compared to its nearest rivals, the Core Ultra 5 225 is a top-tier performer. Its average benchmark score of 36938 is 0% different from the AMD Ryzen 5 5600F, and it is 0.2% faster than the AMD Ryzen 5 5500X3D. This puts it in the same performance class as some of the best mid-range CPUs available. In Roblox, this means the CPU will not hold back the GPU, allowing the system to push very high frame rates at 1080p and 1440p, where the GPU is the primary bottleneck.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a classic scaling pattern. At 1080p, the system is heavily CPU-limited, as shown by the relatively small performance delta between settings (281 FPS to 184 FPS). As resolution increases to 1440p, the GPU becomes more engaged, and the gap between Low and Ultra presets widens. At 4K, the GPU is the definitive bottleneck, and the average FPS drops to a range where the CPU's high single-thread performance becomes less relevant.

This scaling behavior has a clear implication for the system's limiting component. At 1080p, the performance ceiling is likely set by the CPU's ability to process the game's instructions. The fact that the GPU can render frames faster than the CPU can issue them is why the average FPS is so high. However, at 4K, the GPU's fill rate and shading power are overwhelmed by the sheer number of pixels, causing the average FPS to drop significantly, regardless of the CPU's capabilities.

This analysis suggests that users with a 1080p or 1440p high-refresh-rate monitor will get the most out of this combination. The system can easily exceed 144 FPS on high settings, making it ideal for fast-paced Roblox experiences. For 4K users, the system is still capable of providing a smooth 60+ FPS experience on Medium or High settings, but pushing to Ultra will result in frame rates that may not be ideal for all users. The data shows that the RX 6600 is the component that defines the performance ceiling at 4K, while the Core Ultra 5 225 does an excellent job of keeping the system fed at lower resolutions.
