Roblox

Roblox is notoriously light on GPU demand, and this combination of an Intel Core Ultra 5 225 and an NVIDIA GeForce RTX 4080 SUPER transforms the sandbox title into a high-refresh-rate showcase. The data confirms this pairing is massively overqualified for the task, delivering playable frame rates even at 4K Ultra, but the real story lies in how the performance ceiling shifts between presets and resolutions. The benchmark results indicate that the RTX 4080 SUPER is the dominant component, yet the CPU still plays a crucial role in maintaining the extreme frame rates at lower resolutions.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals a system that is primarily GPU-bound at higher resolutions, but becomes increasingly CPU-limited as resolution drops. At 1080p with High settings, the combo produces an average of 515 FPS. Moving to 1440p High drops that to 343 FPS, a 33% reduction. At 4K High, the average falls to 194 FPS, which is a 62% drop from the 1080p figure. This steep decline is a classic sign of the GPU taking on more work per frame, but the absolute numbers remain so high that the RTX 4080 SUPER is never truly stressed.

The pattern holds across other settings. At Low settings, the progression is 640 FPS at 1080p, 427 FPS at 1440p, and 241 FPS at 4K. This 4K result is still far above the 144Hz refresh rate that most high-end monitors offer, indicating that the GPU has ample headroom. The Medium preset shows a similar trajectory: 582 FPS at 1080p, 388 FPS at 1440p, and 220 FPS at 4K, with minimum frame rates of 495, 330, and 187 FPS respectively. The minimums are worth noting because they are all well above 144 FPS, ensuring a smooth experience even in busy scenes.

The most telling data point is the Ultra preset. At 4K Ultra, the average FPS drops to 158, which is still highly playable but represents a significant 62% reduction from the 417 FPS at 1080p Ultra. This scaling suggests that while the GPU is the limiting factor at 4K, the game's engine and the CPU's single-thread performance are what prevent even higher frame rates at 1080p. The difference between 1080p Low (640 FPS) and 1080p Ultra (417 FPS) is 223 FPS, a gap that widens at 1440p (427 vs 279) but narrows at 4K (241 vs 158). This narrowing indicates that the GPU becomes the bottleneck at 4K, while the CPU's ability to feed frames is the ceiling at lower resolutions.

Settings Recommendations

For the best experience, the data suggests that the Medium preset offers the most balanced performance across all resolutions. At 4K, Medium delivers 220 FPS average with a minimum of 187 FPS, which is a 39% improvement over the Ultra preset's 158 FPS average. The visual difference between Medium and Ultra in a game like Roblox is often negligible due to its stylized graphics, making Medium the sweet spot for maximizing frame rates without sacrificing stability. The High preset at 4K (194 FPS average) is also viable, but it sits closer to the Ultra performance level than Medium.

At 1440p, Medium is the clear winner for competitive play. The 388 FPS average with a 330 FPS minimum ensures that even the most demanding moments stay well above the refresh rate of any current monitor. While Low offers a higher average (427 FPS), the visual fidelity loss is unnecessary given that Medium already provides a substantial buffer. For users with 240Hz or 360Hz displays, Low at 1440p might be tempting, but the data shows that Medium only costs 39 FPS on average while providing a significantly better visual experience.

At 1080p, the recommendation becomes more nuanced. The Ultra preset produces 417 FPS, which is still exceptionally high, but the Medium preset's 582 FPS average is 40% higher. For esports titles or games where frame rate is paramount, Medium at 1080p is the optimal choice. The Low preset (640 FPS) offers diminishing returns, as the jump from 582 to 640 FPS is unlikely to be perceptible on most displays. The data strongly indicates that Medium is the recommended preset for this combo, as it provides the best balance of visual quality and performance headroom across all three resolutions.

How This Combo Ranks

Within the benchmark database, this specific combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 4080 SUPER ranks 231st out of 3010 tested combos for Roblox. This places it in the top 7.7% of all configurations, which is a strong result given the game's relatively low system requirements. The high rank is driven primarily by the GPU's raw power, as the RTX 4080 SUPER sits in the 86th percentile of all GPUs tested, while the CPU is in the 85th percentile of all CPUs.

The ranking suggests that this combo outperforms the vast majority of systems in Roblox, but it is not at the absolute top. The fact that 230 other combinations score higher indicates that there are configurations with even more powerful GPUs or CPUs that can push frame rates even higher, particularly at 1080p where CPU limitations become more apparent. However, the performance gap between this combo and the top-ranked ones is likely small in absolute terms, as the frame rates are already well beyond what most displays can show.

In comparison to its nearest rivals, the CPU's average benchmark score is 36938, which is virtually identical to the AMD Ryzen 5 5600F at 36945 (0% delta) and slightly above the AMD Ryzen 5 5500X3D at 37018 (-0.2% delta). This means the CPU is not a differentiator in this pairing. The GPU's average benchmark score of 54209 is similarly close to the NVIDIA GeForce RTX 4080 at 54247 (-0.1% delta), indicating that this combo is essentially equivalent to a standard RTX 4080 setup in terms of raw performance. The 231st rank is a reflection of the balanced but not extreme nature of this pairing.

Measured FPS Breakdown

The measured FPS data provides a comprehensive look at how this combo performs across different settings and resolutions. At 4K (3840x2160), the average frame rates are as follows: Low at 241 FPS, Medium at 220 FPS (with a minimum of 187 FPS and maximum of 253 FPS), High at 194 FPS, and Ultra at 158 FPS. The spread between Low and Ultra is 83 FPS, which is significant but still leaves even the Ultra preset comfortably above 144 FPS.

At 1440p (2560x1440), the performance scales up considerably. Low produces 427 FPS, Medium 388 FPS (min 330, max 447), High 343 FPS, and Ultra 279 FPS. The gap between Low and Ultra here is 148 FPS, showing that the GPU has more headroom at this resolution. The minimum frame rate of 330 FPS on Medium is particularly noteworthy, as it ensures consistent performance even in complex scenes with many players or objects.

At 1080p (1920x1080), the frame rates reach extraordinary levels. Low hits 640 FPS, Medium 582 FPS (min 495, max 669), High 515 FPS, and Ultra 417 FPS. The difference between Low and Ultra is 223 FPS, which is the largest spread across all resolutions. This suggests that at 1080p, the CPU's single-thread performance is the limiting factor, as the GPU is capable of rendering frames much faster than the CPU can issue draw calls.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the primary driver of performance in this combo, particularly at 4K. With 16 GB of GDDR6X memory on a 256-bit bus, it offers 736.3 GB/s of bandwidth, which is more than sufficient for Roblox's texture and geometry demands. The GPU's boost clock of 2550 MHz and its 10240 shading units provide the raw compute power needed to maintain high frame rates, even at 4K Ultra where it still manages 158 FPS.

The GPU's VRAM capacity is a non-factor in this game, as Roblox's assets are relatively simple and unlikely to exceed even a fraction of the 16 GB available. The data confirms this, as the performance difference between Low and Ultra settings at 4K is only 83 FPS, indicating that the GPU is not running out of memory or bandwidth. The RTX 4080 SUPER's architecture, Ada Lovelace, is designed for high-throughput rendering, and its 52.22 TFLOPS of FP32 performance is more than adequate for the game's lighting and shading effects.

The GPU's benchmark scores reflect its high-end positioning. It achieves a Passmark G3D score of 34245 and a Geekbench Vulkan score of 260075, placing it in the 86th percentile of all GPUs. In Roblox, the GPU's role is to ensure that even the most demanding settings are playable at 4K, which it does with ease. The fact that the 4K Ultra average is 158 FPS, well above the 144Hz threshold, demonstrates that this GPU is overkill for the game, but it also guarantees future-proofing for more demanding sandbox experiences.

CPU Role

The Intel Core Ultra 5 225 plays a supporting but critical role in this combo, particularly at lower resolutions. With 10 cores and 10 threads, running at a base clock of 3.30 GHz and a boost clock of 4.90 GHz, this CPU provides the single-thread performance necessary to drive high frame rates in Roblox. The game's engine is known to be sensitive to single-core performance, and the CPU's Cinebench R23 single-core score of 3655 confirms its strength in this area.

The CPU's 20 MB of shared L3 cache and 3 MB per-core L2 cache help reduce latency, which is crucial for maintaining stable frame times in a game that often involves rapid spawning of objects and player interactions. The Passmark single-thread score of 4412 is particularly relevant, as it indicates the CPU's ability to process game logic and physics calculations quickly. This is evident in the 1080p Low result of 640 FPS, where the CPU is the bottleneck, not the GPU.

The CPU's overall benchmark performance places it in the 85th percentile of all CPUs, with an average score of 36938. This is nearly identical to its nearest rivals, including the AMD Ryzen 5 5600F and the AMD Ryzen 5 5500X3D, with deltas of 0% and -0.2% respectively. This means that in CPU-bound scenarios, this combo performs equivalently to those alternatives. However, the CPU's 10 cores and 10 threads are more than sufficient for Roblox, which rarely utilizes more than a few threads. The data shows that the CPU's role is to keep up with the GPU at 1080p and 1440p, and it does so effectively, as evidenced by the high frame rates and the minimal performance gap between Low and Medium settings.
