Roblox

Roblox is a sandbox title that scales dramatically across hardware, and the combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 3080 Ti produces a dataset that reveals clear performance tiers. The measured frames per second (FPS) across three resolutions and four settings presets provide a comprehensive look at how this pairing handles the game. Analysis of the data shows that the RTX 3080 Ti, with its 12 GB of GDDR6X memory, and the Core Ultra 5 225, with its 10 cores and 10 threads, are both heavily utilized, but the performance ceiling varies significantly based on the chosen configuration.

Settings Recommendations

The measured FPS data for this combination in Roblox indicates that the Ultra preset provides the most visually demanding experience, but it comes at a significant cost to frame rates. At 3840x2160, the Ultra preset averages 123 FPS, which is a substantial drop from the High preset's 152 FPS. While 123 FPS is playable, the data shows that the High preset offers a better balance for 4K gaming, as it maintains a higher average frame rate while still providing enhanced visual fidelity over Medium and Low settings.

Moving to 2560x1440, the High preset achieves an average of 268 FPS, which is a strong result and suggests that this is the optimal preset for high-refresh-rate monitors at this resolution. The Ultra preset at this resolution drops to 218 FPS, which is still very smooth but represents a 50 FPS penalty compared to High. The Medium preset at 2560x1440 yields 304 FPS, while Low hits 334 FPS, but the visual quality difference between High and Medium is often more noticeable in a sandbox game where object density and draw distances matter.

At 1920x1080, all presets deliver exceptionally high frame rates, with the Low preset hitting 500 FPS and the Medium preset reaching 455 FPS. The High preset averages 402 FPS, while Ultra falls to 326 FPS. The data suggests that at 1080p, the CPU becomes a more significant factor, as the frame rates are high enough that the GPU is not the primary bottleneck. For the best experience per the measured rows, the High preset at 2560x1440 stands out as the sweet spot, offering 268 FPS which is well above the 144Hz refresh rate common in modern monitors, while still providing a substantial visual upgrade over the Low and Medium presets.

The Ultra preset, while visually impressive, shows diminishing returns at higher resolutions. The data indicates that the performance cost of Ultra over High is consistent: a 29 FPS drop at 4K, a 50 FPS drop at 1440p, and a 76 FPS drop at 1080p. This pattern suggests that the Ultra preset introduces effects that are particularly demanding on the GPU, especially as resolution increases. For users prioritizing frame rate stability, the High preset is the recommended choice across all resolutions, as it consistently offers the best balance between visual quality and performance.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the primary driver of frame rates in Roblox, particularly at higher resolutions and settings. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, providing a memory bandwidth of 912.4 GB/s. This memory configuration is more than sufficient for Roblox, which is not typically a VRAM-intensive title, but the bandwidth ensures that texture streaming and asset loading do not become bottlenecks during gameplay.

The GPU's clock speeds, with a base of 1365 MHz and a boost of 1665 MHz, are relatively modest compared to newer architectures, but the sheer number of shading units—10240—compensates for this. The RTX 3080 Ti delivers 34.10 TFLOPS of FP32 performance, which is substantial for a game like Roblox that relies heavily on simple geometry and particle effects. The benchmark results show that the GPU's PassMark G3D score is 26896, placing it in the 83rd percentile of all GPUs, which corroborates its strong performance in this title.

The data reveals that the GPU is the limiting factor at 4K resolution, where the average FPS drops from 500 at 1080p Low to 189 at 4K Low. This indicates that the GPU is being pushed to its limits at higher pixel counts. The RTX 3080 Ti's performance in Roblox is also notable in comparison to its nearest rivals. The data lists the AMD Radeon Pro 5300 as having an average benchmark score that is 0.8% higher, while the NVIDIA Tesla M40 24 GB is 1.2% lower. This shows that the RTX 3080 Ti is a capable card, but not the absolute top performer in synthetic benchmarks, which aligns with its 83rd percentile ranking.

The GPU's memory clock of 1188 MHz, with an effective speed of 19 Gbps, contributes to the high bandwidth, but in Roblox, the data suggests that raw compute power is more important than memory speed. The measured FPS at 4K Ultra is 123, which is a playable frame rate, but it shows that the GPU is working hard to maintain that level. The GPU's role becomes less dominant at 1080p, where the frame rates exceed 400 FPS at High settings, indicating that the CPU is starting to play a more significant role in determining the final output.

CPU Role

The Intel Core Ultra 5 225 is a 10-core, 10-thread processor based on the Arrow Lake architecture, manufactured on a 3 nm process by TSMC. Its base clock of 3.30 GHz and boost clock of 4.90 GHz are competitive for gaming, and the 20 MB of shared L3 cache helps with data access efficiency. The CPU's benchmark scores, such as a Cinebench R23 multi-core score of 25891 and a single-core score of 3655, indicate that it is a strong performer for both multi-threaded and single-threaded workloads.

In Roblox, the CPU's role is most apparent at 1080p resolution, where the frame rates are high enough to expose CPU limitations. At 1080p Low, the average FPS is 500, while at 1080p Ultra, it drops to 326. This spread of 174 FPS is larger than the spread at 4K, where Low yields 189 FPS and Ultra yields 123 FPS, a difference of only 66 FPS. The data suggests that at lower resolutions, the CPU's ability to feed the GPU with draw calls becomes the bottleneck, and the Core Ultra 5 225's 10 threads are being utilized to their fullest.

The CPU's PassMark single-thread score of 4412 and multi-thread score of 30459 provide context for its gaming performance. The single-thread performance is crucial for Roblox, as the game's engine often relies on a few primary threads for game logic and physics. The Core Ultra 5 225's boost clock of 4.90 GHz ensures that these threads can be executed quickly, which is reflected in the high frame rates at 1080p. The CPU's 85th percentile ranking against all CPUs further confirms its capability.

Compared to its nearest rivals, the Core Ultra 5 225 is closely matched with the AMD Ryzen 5 5600F, which has an average score that is essentially identical (0% delta). The AMD Ryzen 5 5500X3D is 0.2% lower, and the AMD Ryzen AI 7 PRO 450 is 0.4% lower. This indicates that the Core Ultra 5 225 is a balanced processor that does not significantly bottleneck the RTX 3080 Ti in Roblox, even at high frame rates. At 1440p, the CPU's influence is still present but lessened, as the GPU begins to take on more of the rendering load, resulting in frame rates that are still very high but not as CPU-bound as at 1080p.

How This Combo Ranks

The combination of the Intel Core Ultra 5 225 and NVIDIA GeForce RTX 3080 Ti ranks 766th out of 3010 tested combos in Roblox. This places it in the top 25% of all tested configurations, which is a strong result given the hardware's specifications. The ranking suggests that this combo is well-balanced for Roblox, with neither component being a severe bottleneck for the other.

The rank of 766 is more indicative of the GPU's influence, as the RTX 3080 Ti's 83rd percentile ranking among GPUs is slightly lower than the CPU's 85th percentile ranking among CPUs. This implies that the GPU is the more limiting factor in this pairing, which is consistent with the resolution scaling data that shows frame rates dropping more significantly at higher resolutions. The combo's rank also reflects that while the RTX 3080 Ti is a high-end card, it is not the absolute fastest, and there are many combinations with newer or more powerful GPUs that achieve higher frame rates.

In the context of the benchmark database, this rank means that users can expect a very playable experience in Roblox at all settings and resolutions, with the only caveat being that the Ultra preset at 4K might not be optimal for those seeking the highest refresh rates. The data shows that the combo is significantly faster than many others, as the rank of 766 out of 3010 indicates that the majority of tested combos (over 2200) are slower. This confirms the raw performance of the RTX 3080 Ti and the efficiency of the Core Ultra 5 225.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases from 1920x1080 to 3840x2160. At the High settings preset, the average FPS drops from 402 at 1080p to 268 at 1440p, and then to 152 at 4K. This represents a 33% decrease in FPS when moving from 1080p to 1440p, and an additional 43% decrease when moving from 1440p to 4K. This scaling is typical of a GPU-bound scenario, where the RTX 3080 Ti's rendering workload increases with pixel count.

The data also shows that the scaling factor is consistent across presets. For the Low preset, the FPS drops from 500 at 1080p to 334 at 1440p, and then to 189 at 4K. This is a similar proportional drop to the High preset, indicating that the GPU is the primary limiter in both cases. However, the absolute frame rates at 1080p are so high (500 FPS) that the CPU's role becomes more significant at that resolution. This is evidenced by the fact that the difference between Low and Ultra at 1080p is 174 FPS, while at 4K, the difference is only 66 FPS.

This pattern suggests that the Core Ultra 5 225 is capable of driving very high frame rates at 1080p, but the RTX 3080 Ti cannot maintain those rates as the resolution increases. The 4K results, where the Ultra preset averages 123 FPS, show that the GPU is the limiting component at that resolution. The data indicates that for users with 1440p monitors, the combo is well-suited for high refresh rates, as even the Ultra preset achieves 218 FPS. For 4K users, the High preset is recommended to maintain a frame rate above 150 FPS, as the Ultra preset's 123 FPS is still smooth but leaves less headroom for demanding scenes.

Measured FPS Breakdown

The complete measured FPS data for this combo is as follows. At 1920x1080, the Low preset averages 500 FPS, the Medium preset averages 455 FPS with a minimum of 387 FPS and a maximum of 523 FPS, the High preset averages 402 FPS, and the Ultra preset averages 326 FPS. These numbers indicate that at 1080p, the combo is capable of pushing well beyond the refresh rates of most monitors, even at the highest settings.

The frame rates here are still very high, and the combo can easily drive a 144Hz or 165Hz monitor at High settings without issue. The minimum FPS of 258 FPS at Medium settings suggests that the combo maintains consistent performance without major dips.

At 3840x2160, the Low preset averages 189 FPS, the Medium preset averages 172 FPS with a minimum of 146 FPS and a maximum of 197 FPS, the High preset averages 152 FPS, and the Ultra preset averages 123 FPS. The 4K results show that the combo is capable of 4K gaming, but the frame rates are lower than at lower resolutions. The High preset at 152 FPS is a good target for 4K, as it provides a smooth experience. The Ultra preset at 123 FPS is still playable, but the data shows that it is the most demanding configuration, and users might prefer to use High for a more consistent frame rate.
