Roblox

Roblox is a notoriously CPU-bound sandbox title, and the data for the Intel Core Ultra 9 290K Plus paired with the NVIDIA GeForce RTX 5070 Ti confirms this dynamic. This combination delivers exceptionally high frame rates across all tested resolutions, but the scaling pattern reveals where the bottleneck lies. At 1080p with Low settings, the combo achieves an average of 606 FPS, which stands as the peak performance in this dataset. Moving to 1440p Low, the average drops to 404 FPS, and at 4K Low, it settles at 229 FPS. This represents a 62% reduction in average FPS from 1080p to 4K at the lowest settings, which is a substantial scaling penalty. The pattern suggests that while the GPU is being increasingly utilized at higher resolutions, the sheer speed of the CPU at lower resolutions is what allows these triple-digit figures to exist in the first place. The game's engine, which often has its frame rate tied to logic updates, appears to benefit enormously from the Ultra 9's 5.80 GHz boost clock.

Resolution Scaling

The way average FPS scales with resolution in Roblox points directly at the primary limiting component shifting between the CPU and GPU. At 1080p, the performance is clearly CPU-limited. The jump from Low (606 FPS) to Ultra (395 FPS) is a 35% performance hit, which is a smaller relative drop than what is seen at higher resolutions. This indicates that the RTX 5070 Ti is not being fully taxed at 1080p, as the CPU is feeding frames as fast as the game engine will allow. The data shows that even at the most demanding 1080p preset, the system still produces an average of 395 FPS, a number that far exceeds the refresh rate of any mainstream monitor.

When moving to 2560x1440, the GPU begins to take on more responsibility, but the CPU still holds significant sway. The average FPS at 1440p Low is 404, which is only a 33% drop from the 1080p Low result. However, the gap between Low and Ultra widens, with the Ultra preset producing 264 FPS. This is a 35% reduction from the Low preset at the same resolution, showing that the graphical load is starting to matter more. The scaling from 1080p to 1440p at Medium settings shows a drop from 551 FPS to 368 FPS, a 33% reduction. This consistency in the scaling percentage across presets suggests that the CPU is still the main driver of performance, with the GPU handling the extra pixels without causing a bottleneck.

The most telling data comes from the 4K results. At 3840x2160, the Low preset averages 229 FPS, and the Ultra preset averages 149 FPS. The scaling from 1080p Low to 4K Low is a 62% drop, while the scaling from 1440p Low to 4K Low is a 43% drop. This shows that at 4K, the GPU is finally becoming the limiting factor, as the pixel throughput demand increases significantly. The difference between Low and Ultra at 4K is 35% (229 FPS to 149 FPS), which is more pronounced than the 1080p difference, indicating that the RTX 5070 Ti's 16 GB of GDDR7 memory and 896.0 GB/s bandwidth are being utilized more heavily. The benchmark results indicate that this system is potent enough to keep Roblox well above 144 FPS even at 4K Ultra, but the diminishing returns from lowering settings are clear as the resolution climbs.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target refresh rate and resolution. For 1080p users with a 240 Hz monitor, the Low preset provides the highest average FPS (606) and eliminates any risk of hitting a frame cap, but the Medium preset also offers an excellent experience. The Medium preset at 1080p averages 551 FPS with a minimum of 468 FPS, which is still far above any current display's refresh rate, making it the better choice for visual fidelity without sacrificing smoothness. The Ultra preset at 1080p, which averages 395 FPS, is also viable, but it offers diminishing returns in visual quality for the 35% performance drop compared to Low.

For 1440p, the Medium preset is the sweet spot for high-refresh-rate displays. It averages 368 FPS with a minimum of 313 FPS, which is sufficient for a 300 Hz monitor. The High preset at 1440p averages 325 FPS, which is also excellent, but the Medium preset's higher minimum FPS (313 vs. the High preset's unknown minimum) suggests more consistent frame pacing. The Ultra preset at 1440p averages 264 FPS, which is still very high and suitable for a 240 Hz display. At 4K, the High preset is recommended for the best balance, offering an average of 184 FPS. The Medium preset at 4K averages 208 FPS, but the High preset likely offers better visual quality for a small drop in performance. The Ultra preset at 4K, at 149 FPS, is still playable on a 144 Hz monitor, but the drop to below 150 FPS is noticeable. For the absolute smoothest experience at 4K, the Low preset at 229 FPS is available, but the visual compromises are significant.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor based on the Arrow Lake Refresh architecture, built on a 3 nm process by TSMC. Its base clock is 3.70 GHz, but its boost clock of 5.80 GHz is the key specification for Roblox. The game is known for its single-threaded nature, and the CPU's Cinebench R23 single-core score of 7303 and Passmark single-thread score of 4823 demonstrate its dominance in this area. The data suggests that the CPU's massive core count (24 cores) is less important for Roblox than its clock speed. However, the high boost clock ensures that the game's main logic thread is processed as quickly as possible, which directly translates to the high average FPS seen in the measured results.

The CPU's memory support also plays a role. It supports dual-channel DDR5 memory with a bandwidth of 115.2 GB/s, which is sufficient to feed the CPU's cores. The L3 cache is 36 MB shared, which helps keep frequently accessed data close to the cores. While the GPU is responsible for rendering the game's simple geometry, the CPU is responsible for handling the physics, user interactions, and game state. The benchmark results indicate that this CPU is so fast that even at 4K with Ultra settings, the system can maintain an average of 149 FPS. This confirms the CPU's ability to keep up with the GPU's rendering output. The data shows that while the GPU is a capable partner, it is the Ultra 9 290K Plus's raw single-thread power that allows this combo to achieve a rank of 296 out of 3010 in Roblox.
