Roblox

Roblox is a sandbox game that scales across a wide range of hardware, but the data for the Intel Core Ultra 9 290K Plus + Intel Arc B390 combination reveals a specific performance profile. The measured frames per second (FPS) across three resolutions and four settings presets show that this integrated graphics solution is capable of playable frame rates, though it is not a high-performance part. The Arc B390, as an integrated graphics processor (IGP), relies on system memory and its modest execution units to render the game, and the results indicate that both resolution and settings have a significant impact on the final experience.

Settings Recommendations

The measured data provides a clear hierarchy of performance across the four available presets: Low, Medium, High, and Ultra. At 1920x1080, the Low preset delivers an average of 171 FPS, which is the highest frame rate recorded for this combo. The Medium preset follows at 155 FPS, High drops to 137 FPS, and Ultra falls to 111 FPS. The difference between Low and Ultra at 1080p is 60 FPS, a substantial gap that underscores the cost of the higher graphical fidelity options. For players prioritizing maximum smoothness on a standard 1080p display, the Low preset offers the most headroom, while the Medium preset still provides a very fluid experience with a 155 FPS average.

Moving to 2560x1440, the pattern shifts. The Low preset averages 114 FPS, Medium 104 FPS, High 92 FPS, and Ultra 74 FPS. The relative drop from 1080p is noticeable, but all presets remain above the 60 FPS threshold commonly considered the baseline for comfortable play. At this resolution, the Medium preset appears to be the sweet spot, as it maintains a 104 FPS average while likely providing a more visually rich scene than Low. The High preset is also viable at 92 FPS, but the margin between Medium and High is only 12 FPS, whereas the jump from Low to Medium is 10 FPS. The data suggests that Medium offers a balanced trade-off between visual quality and performance at 1440p.

At 3840x2160, the limitations of the Arc B390 become evident. The Low preset averages 64 FPS, which is just above the 60 FPS target. Medium averages 59 FPS, High averages 52 FPS, and Ultra drops to 42 FPS. Only the Low preset consistently hits the 60 FPS mark, and even then, the margin is slim. The Medium preset, with an average of 59 FPS, is borderline, and the min FPS of 50 recorded at this setting suggests potential stutters in busy scenes. For 4K gaming, the Low preset is the only reliable choice for a smooth experience, while Medium may be acceptable for players who tolerate occasional drops below 60 FPS. The Ultra preset is not recommended at this resolution, as the 42 FPS average indicates a significant compromise in responsiveness.

GPU Role

The Intel Arc B390 is an integrated graphics processor based on the Xe3-LPG architecture, built on a 3 nm process. It features 1536 shading units, 48 texture mapping units, and 24 raster output pipelines. Its boost clock is rated at 2500 MHz, with a base clock of 300 MHz. The GPU’s memory configuration is entirely system-shared, meaning it has no dedicated video memory. This is a critical factor, as the bandwidth and capacity are system-dependent, which directly impacts performance at higher resolutions and settings. The GPU’s pixel rate is 60.00 GPixel/s, and its texture rate is 120.0 GTexel/s, figures that are modest for modern gaming but sufficient for a lighter title like Roblox.

The benchmark data for the Arc B390 shows a 3DMark Steel Nomad DX12 score of 1482. This places it in the 9th percentile of all GPUs, indicating that it is a low-performance part. Its nearest rivals, based on average benchmark scores, are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710, with delta percentages of 1.3, 1.5, 2.5, and 2.7 respectively. These are all older, entry-level discrete GPUs, which puts the Arc B390’s performance into perspective. In Roblox, the GPU’s role is to handle the rendering of the game’s blocky geometry and simple textures. The measured FPS shows that the GPU becomes a bottleneck at 4K, where the pixel fill rate and memory bandwidth are stretched thin. The shift from 1080p to 4K at Low settings results in a drop from 171 FPS to 64 FPS, a 107 FPS decrease, which is a direct consequence of the shared memory architecture and the GPU’s limited compute resources.

CPU Role

The Intel Core Ultra 9 290K Plus is a high-end desktop processor with 24 cores and 24 threads, based on the Arrow Lake Refresh architecture. It has a base clock of 3.70 GHz and a boost clock of 5.80 GHz. The CPU’s cache configuration includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3 cache. It supports dual-channel DDR5 memory with a bandwidth of 115.2 GB/s. This is a powerful processor, as evidenced by its Cinebench scores: 5214 in R15 multi-core, 736 in R15 single-core, 21727 in R20 multi-core, 3067 in R20 single-core, and 51731 in R23 multi-core, with a single-core score of 7303. Its Passmark single-thread score is 4823, and its multithread score is 60860.

In Roblox, the CPU is responsible for game logic, physics, and scripting, which can be demanding in complex user-generated worlds. The high single-thread performance of the Core Ultra 9 290K Plus, indicated by its R23 single-core score of 7303, is well-suited to Roblox's often single-threaded workload. The data shows that at 1080p with Low settings, the average FPS of 171 is likely CPU-limited, as the GPU has less work to do. The CPU’s 24 cores and 24 threads provide ample headroom for background tasks and any multithreaded aspects of the game. The processor’s performance percentile of 96 versus all CPUs confirms its top-tier status. Its nearest rivals include the Intel Core Ultra 9 285K with a 0.2% delta, the AMD EPYC 4584PX at 1.1%, and the AMD EPYC 9135 at 1.2%, showing that the 290K Plus is at the very top of the performance stack. In this combo, the CPU is not the limiting factor in most scenarios; rather, the GPU’s capabilities dictate the achievable frame rates.

How This Combo Ranks

The combination of the Intel Core Ultra 9 290K Plus and Intel Arc B390 is ranked 2661 out of 3010 tested combos in Roblox. This ranking places it in the lower 12th percentile of all combinations, which is a direct reflection of the GPU’s performance limitations. The CPU is a top-tier part, but the GPU is a low-tier integrated solution, and the overall combo performance is dragged down by the graphics side. This rank indicates that while the CPU can push high frame rates in CPU-bound scenarios, the GPU cannot maintain those rates when graphical demands increase.

The data shows that the combo performs best at low resolutions and low settings, where the GPU load is minimized. At 1080p Low, the 171 FPS average is relatively strong, but it falls to 111 FPS at 1080p Ultra. This is a 35% reduction in performance from the lowest to the highest settings at the same resolution. The ranking of 2661 out of 3010 suggests that this is not a competitive gaming setup for Roblox. Most other tested combinations, which likely include discrete GPUs, would outperform this setup. The combo’s rank is a clear indicator that the Arc B390 is the bottleneck, as the Core Ultra 9 290K Plus is among the fastest CPUs available. Users with this combo should expect frame rates that are playable but far from the high refresh rates achievable with dedicated graphics cards.

Resolution Scaling

The measured FPS data across resolutions reveals how the system scales with pixel count. At Low settings, the average FPS drops from 171 at 1080p to 114 at 1440p and then to 64 at 4K. This represents a 33% decrease from 1080p to 1440p and a 44% decrease from 1440p to 4K. The scaling is not linear, indicating that the GPU is becoming increasingly strained as the pixel count grows. At Medium settings, the pattern is similar: 155 FPS at 1080p, 104 FPS at 1440p, and 59 FPS at 4K. The drop from 1080p to 4K is 96 FPS, a 62% reduction.

This scaling behavior points to the GPU as the limiting component. A system that is CPU-limited would show a smaller FPS drop when resolution increases, as the CPU’s workload remains constant while the GPU’s workload increases. Here, the substantial FPS drops at higher resolutions indicate that the Arc B390’s rendering capabilities are being saturated. The fact that the 4K Medium preset has a min FPS of 50 and a max of 67, while the average is 59, shows that the frame times are inconsistent, likely due to memory bandwidth constraints from the system-shared memory. At 1080p, the CPU is more likely to be the limiting factor, as the GPU can keep up with the lower pixel count. The data suggests that this combo is best used at 1080p or 1440p, where the frame rates are more stable and the GPU is not overwhelmed.

Measured FPS Breakdown

The following table details the exact measured average FPS for each resolution and settings preset combination:

• 1920x1080 (1080p):
• Low: 171 FPS average
• Medium: 155 FPS average, with a min of 132 and max of 179
• High: 137 FPS average
• Ultra: 111 FPS average

• 2560x1440 (1440p):
• Low: 114 FPS average
• Medium: 104 FPS average, with a min of 88 and max of 119
• High: 92 FPS average
• Ultra: 74 FPS average

• 3840x2160 (4K):
• Low: 64 FPS average
• Medium: 59 FPS average, with a min of 50 and max of 67
• High: 52 FPS average
• Ultra: 42 FPS average

The data shows a consistent trend: each increase in settings tier reduces the average FPS by a similar margin. At 1080p, the difference between Low and Medium is 16 FPS, Medium to High is 18 FPS, and High to Ultra is 26 FPS. This suggests that the Ultra preset is disproportionately more demanding than the others. At 1440p, the differences are 10 FPS, 12 FPS, and 18 FPS, respectively. At 4K, the differences are 5 FPS, 7 FPS, and 10 FPS. The smaller absolute differences at higher resolutions indicate that the GPU is already near its limits, and the settings have less of an impact on the final frame rate. The min and max FPS values for Medium settings show a spread of 47 FPS at 1080p (132 to 179), 31 FPS at 1440p (88 to 119), and 17 FPS at 4K (50 to 67). This tightening spread at higher resolutions further confirms that the GPU is the primary bottleneck.
