Roblox

Roblox is not a demanding title by modern standards, but this combination of the Intel Core Ultra 5 235 and the NVIDIA GeForce RTX 3080 produces a remarkable spread of results across its four quality presets. The data shows that the game becomes almost entirely CPU-bound at lower resolutions and settings, while the GPU begins to assert itself at 4K with maximum quality. The measured frames per second (FPS) reveal that the sweet spot for this hardware pairing is the High preset, which provides a substantial visual upgrade over Low and Medium without the steep performance penalty seen at Ultra.

Settings Recommendations

The benchmark rows for this combo include four settings presets—Low, Medium, High, and Ultra—measured at three resolutions. Analyzing the data, the High preset offers the best balance of image quality and performance. At 1920x1080, High delivers an average of 387 FPS, which is 51 FPS lower than Medium's 438 FPS but 73 FPS higher than Ultra's 314 FPS. The gap between High and Ultra is consistent across all resolutions, suggesting that Ultra enables expensive effects that do not proportionally improve the visual experience in a sandbox game like Roblox.

At 2560x1440, the High preset maintains an average of 259 FPS, which is still far above the 144 Hz refresh rate of most high-end monitors. The Medium preset is only 34 FPS faster at 293 FPS, while Ultra drops to 210 FPS. The 4K results are the most telling: High produces 146 FPS average, Medium 165 FPS, and Ultra 119 FPS. The delta between High and Ultra at 4K is 27 FPS, or about 18.5%, which is a significant loss for marginal fidelity gains in a game with Roblox's blocky aesthetic.

Low settings are measurably faster—482 FPS at 1080p and 321 FPS at 1440p—but the visual degradation in a game that already uses simple geometry makes this preset unnecessary given the hardware's headroom. Medium provides a middle ground with 438 FPS at 1080p and 293 FPS at 1440p, but the jump to High costs only about 12% performance at those resolutions while delivering noticeably better shadows and textures. The recommendation is clear: use High at all three resolutions. For 4K, if you have a 144 Hz display, the 146 FPS average is sufficient, though you may occasionally dip below that threshold in busy scenes.

FAQ

Q: What is the best settings preset for this CPU/GPU combo in Roblox?

A: The High preset provides the best experience. At 1080p, it averages 387 FPS, at 1440p it averages 259 FPS, and at 4K it averages 146 FPS. These numbers are substantially higher than the Ultra preset (314, 210, and 119 FPS respectively) while offering most of the visual improvements.

Q: Is the RTX 3080 bottlenecked by the Core Ultra 5 235 in this game?

A: At lower resolutions and settings, yes. The data shows that at 1080p Low, the combo achieves 482 FPS, which is likely near the CPU's limit for game logic and draw calls. At 4K Ultra, the GPU becomes the limiting factor, as the average drops to 119 FPS, indicating the graphics card's workload increases significantly with resolution and quality.

Q: How does the Ultra preset compare to High in terms of FPS loss?

A: The Ultra preset is consistently slower than High. At 1080p, Ultra is 73 FPS slower (314 vs 387). At 1440p, the gap widens to 49 FPS (210 vs 259). At 4K, Ultra is 27 FPS slower (119 vs 146). The percentage loss increases with resolution, from 18.9% at 1080p to 18.5% at 4K.

Q: Can this combo maintain 144 FPS at 4K?

A: Yes, but only with the High or Medium presets. High averages 146 FPS, and Medium averages 165 FPS. The Low preset averages 182 FPS at 4K. The Ultra preset falls short with a 119 FPS average, which cannot sustain a 144 Hz refresh rate.

Q: What is the performance difference between Low and High settings at 1440p?

A: Low averages 321 FPS, while High averages 259 FPS. This represents a 62 FPS difference, or about 19.3% slower for High. The trade-off is improved visual fidelity, which is a reasonable cost given that both presets are far above typical monitor refresh rates.

Q: Does the game scale well with resolution for this hardware?

A: The scaling is non-linear. From 1080p to 1440p on High, the FPS drops from 387 to 259, a 33% reduction. From 1440p to 4K on High, the FPS drops from 259 to 146, a 43.6% reduction. This indicates the GPU becomes more relevant at higher resolutions, but the CPU still plays a significant role in Roblox's performance ceiling.

Resolution Scaling

The measured FPS data reveals a clear pattern of diminishing returns as resolution increases. At the High preset, the frame rate drops from 387 FPS at 1920x1080 to 259 FPS at 2560x1440, a decrease of 128 FPS or 33.1%. Moving from 1440p to 3840x2160, the High preset drops further to 146 FPS, a reduction of 113 FPS or 43.6%. This steepening curve indicates that the RTX 3080's rendering workload grows faster than the pixel count alone would suggest, likely due to increased shading and texture sampling at higher resolutions.

The Low preset shows a similar trend but with slightly different magnitudes. At 1080p Low, the combo achieves 482 FPS. At 1440p Low, it drops to 321 FPS, a 33.4% reduction. At 4K Low, the average is 182 FPS, which is a 43.3% drop from 1440p. The consistency of these percentage drops across presets (roughly 33% for the first step and 43% for the second) suggests that the rendering pipeline scales predictably with resolution, independent of quality settings.

What this scaling tells us about the limiting component is nuanced. At 1080p, the 482 FPS Low result is extraordinarily high, and it is likely that the CPU's single-thread performance (a Cinebench R23 single-core score of 2085) is the bottleneck, as Roblox's engine is known to be single-threaded for its main game loop. The Core Ultra 5 235 has 14 cores and 14 threads, with a boost clock of 5.00 GHz, which should handle the game's logic efficiently. However, the fact that the 4K Low result (182 FPS) is still extremely high indicates the GPU is not severely challenged even at 4K with minimal effects.

The real bottleneck shift occurs at Ultra settings. At 4K Ultra, the FPS drops to 119, which is only 38% of the 1080p Ultra result (314 FPS). This larger relative drop (62% loss vs 50% loss for High) suggests that Ultra enables GPU-intensive features like higher-quality shadows and post-processing that stress the RTX 3080's 10 GB of GDDR6X memory and 8704 shading units. The GPU's 68 RT cores and 272 tensor cores are not heavily utilized in Roblox, but the raw compute load from Ultra effects is enough to bring the 4K average below 120 FPS.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates. The Low preset averages 482 FPS, which is the fastest measured result in the entire dataset. Medium follows at 438 FPS, with a minimum of 373 FPS and a maximum of 504 FPS. High drops to 387 FPS, and Ultra is the slowest at 314 FPS. The spread from Low to Ultra is 168 FPS, or 34.9%, meaning that even at the most demanding settings, the system is never below 300 FPS at 1080p.

The 2560x1440 results show a similar hierarchy with lower absolute numbers. Low averages 321 FPS, Medium 293 FPS (min 249, max 336), High 259 FPS, and Ultra 210 FPS. The delta between Low and Ultra is 111 FPS, or 34.6%, which mirrors the 1080p percentage. This consistency indicates that the CPU is not being overwhelmed at 1440p, as the relative performance penalty for higher settings remains stable.

At 3840x2160, the RTX 3080's limits become more apparent. Low averages 182 FPS, Medium 165 FPS (min 141, max 190), High 146 FPS, and Ultra 119 FPS. The percentage drop from Low to Ultra is 34.6%, consistent with lower resolutions, but the absolute numbers are now in a range where display refresh rates matter. The 4K Medium result has a minimum of 141 FPS, which could cause stutters on a 144 Hz monitor during busy scenes. The 4K Ultra average of 119 FPS is below 120, meaning it cannot sustain high-refresh gaming.

Notably, only the Medium preset at each resolution has recorded minimum and maximum FPS values. At 1080p Medium, the range is 373 to 504 FPS. At 1440p Medium, it is 249 to 336 FPS. At 4K Medium, it is 141 to 190 FPS. These ranges show that the game's frame pacing is generally stable, with the minimum being about 85% of the average in each case. The other presets lack min/max data, but the averages suggest similar stability.

How This Combo Ranks

The combination of the Intel Core Ultra 5 235 and the NVIDIA GeForce RTX 3080 achieves a rank of 822 out of 3010 tested combos in Roblox. This places it in the top 27.3% of all system pairings, which is a strong result for a game that is not typically used as a benchmark title. The rank reflects the system's ability to maintain high frame rates across all resolutions and settings, as demonstrated by the measured data showing no result below 119 FPS average.

The CPU's individual percentile ranking is 89th percentile among all CPUs, with an average benchmark score of 46062. This is a very strong showing, placing it ahead of 89% of processors tested. The nearest rivals in the CPU benchmark database are the AMD Ryzen AI 9 HX 375 (avg score 46030, delta 0.1%), the Intel Core i9-13900HX (avg score 46098, delta -0.1%), and the AMD EPYC 4364P (avg score 45970, delta 0.2%). The Core Ultra 5 235 sits essentially at parity with these chips, within 0.2% of each, indicating that its 14 cores and 14 threads deliver competitive throughput for synthetic workloads.

The GPU's percentile ranking is 68th percentile among all GPUs, with an average benchmark score of 23172. This is a lower relative standing than the CPU, but it reflects the RTX 3080's age and the presence of newer graphics cards in the database. The nearest rivals include the NVIDIA P106-100 (avg score 23249, delta -0.3%), the AMD Radeon Pro Vega 16 (avg score 23250, delta -0.3%), and the AMD Radeon RX 6600M (avg score 23273, delta -0.4%). The RTX 3080 is within 0.4% of these GPUs, which is surprising given the architectural differences, but the synthetic scores suggest comparable compute performance in certain workloads.

For Roblox specifically, the combo's rank of 822 out of 3010 reflects the CPU's strength. Since Roblox is not heavily GPU-bound at lower settings, the Core Ultra 5 235's high single-thread performance (Cinebench R23 single-core score of 2085) directly contributes to the exceptional frame rates seen at 1080p and 1440p. The GPU only becomes a meaningful factor at 4K Ultra, where the rank might be slightly lower due to the 10 GB memory capacity and the 29.77 TFLOPS FP32 throughput being taxed by higher quality effects.

CPU Role

The Intel Core Ultra 5 235 is a 14-core, 14-thread processor based on the Arrow Lake architecture, built on a 3 nm process by TSMC. It has a base clock of 3.40 GHz and a boost clock of 5.00 GHz, and it is rated for a 65 W TDP. The CPU's cache hierarchy includes 192 KB of L1 per core, 3 MB of L2 per core, and 24 MB of shared L3 cache. This configuration is unusual in that it lacks hyper-threading, meaning each core handles only one thread, which can be a disadvantage in heavily multi-threaded workloads but is less relevant for Roblox.

In Roblox, the game's engine is primarily single-threaded for its main simulation and rendering logic. The Core Ultra 5 235's single-thread performance is strong, as evidenced by its Cinebench R23 single-core score of 2085 and its Passmark single-thread score of 4516. These scores indicate that the CPU can process the game's instructions quickly, which explains why the combo achieves 482 FPS at 1080p Low. The boost clock of 5.00 GHz is critical here, as Roblox's frame rate is often limited by the fastest single core's ability to issue draw calls and update game state.

The multi-threaded performance of the Core Ultra 5 235 is also impressive, with a Cinebench R23 multi-core score of 14769 and a Passmark multi-thread score of 37816. While Roblox does not fully utilize all 14 cores, background tasks and other system processes can run on the remaining cores without interfering with the game's primary thread. This is a benefit of having a high core count, as it prevents other applications from stealing CPU time from the game.

The data shows that the CPU is the limiting factor at 1080p and 1440p, especially at lower settings. The fact that the FPS drops by about 33% when moving from 1080p to 1440p on the same settings suggests that the GPU is not the bottleneck, as the pixel fill rate would cause a more dramatic drop if it were. Instead, the CPU's ability to feed the GPU with geometry and draw calls reaches a ceiling around 480-500 FPS, which is why the Low preset at 1080p (482 FPS) is not much faster than the Low preset at 1440p (321 FPS) when adjusted for pixel count. The 5.00 GHz boost clock and 24 MB of L3 cache help maintain high frame rates, but Roblox's engine is ultimately limited by its own single-threaded nature, not by the hardware's capability.
