Roblox

Roblox is a sandbox title that behaves differently from most modern AAA releases, and the measured data for the Intel Core Ultra 9 290K Plus paired with the Intel Arc B570 reflects that. The combination produces a wide spread of frame rates depending on resolution and quality preset, ranging from 65 FPS at 4K Ultra to 262 FPS at 1080p Low. This analysis walks through the measured rows to explain what those numbers indicate about the CPU, GPU, and how to configure the game for the best experience.

Resolution Scaling

The measured FPS data shows a clear and consistent drop as resolution increases, which is the expected pattern for a GPU-bound scenario at higher pixel counts. At 1080p High, the combo averages 211 FPS. Moving to 1440p High, that number falls to 141 FPS, a reduction of 70 FPS. At 4K High, the average drops further to 80 FPS, which is a 131 FPS decline from the 1080p result. This scaling pattern—roughly a 33% drop from 1080p to 1440p and a 62% drop from 1080p to 4K at High settings—indicates that the GPU is the primary limiting factor as resolution climbs, which is typical because higher resolutions increase the pixel fill rate demand.

The Low preset shows a similar trajectory. At 1080p Low, the average is 262 FPS. At 1440p Low, it falls to 175 FPS, and at 4K Low, it reaches 99 FPS. The percentage drops are slightly different: 1440p Low is about 33% slower than 1080p Low, while 4K Low is about 62% slower. This consistency across presets reinforces that resolution scaling is driven by the rendering pipeline rather than by a specific setting.

The Medium preset provides the only complete min/max FPS data in the measured rows, which gives additional insight into frame time consistency. At 1080p Medium, the average is 239 FPS with a minimum of 203 and a maximum of 275, meaning the frame rate stays within a 72 FPS range. At 1440p Medium, the average drops to 159 FPS with a minimum of 135 and a maximum of 183, a spread of 48 FPS. At 4K Medium, the average is 90 FPS with a minimum of 77 and a maximum of 104, a spread of 27 FPS. The shrinking absolute spread at higher resolutions suggests that the GPU is more consistently saturated, reducing the variability that comes from CPU-driven frame pacing at lower resolutions.

The 4K Ultra preset yields the lowest average at 65 FPS, which is the only measured result below the 80 FPS threshold seen at 4K High. The gap between 4K High and 4K Ultra is 15 FPS, while the gap between 4K Medium and 4K High is 10 FPS. This indicates that the Ultra preset imposes a significant additional load on the GPU, likely through more demanding shading and post-processing effects that scale with pixel count.

CPU Role

The Intel Core Ultra 9 290K Plus is a 24-core, 24-thread processor with a base clock of 3.70 GHz and a boost clock of 5.80 GHz. Its cache configuration includes 192 KB of L1 per core, 3 MB of L2 per core, and 36 MB of shared L3. The CPU’s benchmark scores are strong: it achieves 51,731 in Cinebench R23 multi-core and 7,303 in single-core, placing it in the 96th percentile of all CPUs. Its average benchmark score is 84,003, which is 0.2% higher than the Intel Core Ultra 9 285K and 1.1% higher than the AMD EPYC 4584PX.

In Roblox, the CPU’s role appears to be secondary to the GPU at higher resolutions, but it becomes more relevant at lower resolutions where the frame rate ceiling is higher. The 1080p Low result of 262 FPS is the highest average recorded, and it suggests that the CPU is capable of feeding the GPU enough data to reach that level. The fact that 1080p Medium reaches 239 FPS and 1080p High reaches 211 FPS indicates that even with a high-core-count CPU, the game’s single-threaded or lightly-threaded workload can still push the CPU to generate high frame rates without bottlenecking the GPU.

The CPU’s single-core performance, as measured by Cinebench R23 single-core score of 7,303, is likely a key factor in these high FPS figures. Roblox is known for being sensitive to single-thread performance, and the boost clock of 5.80 GHz provides substantial headroom. The 24 threads are more than enough for a sandbox game that typically does not scale across many cores, so the processor’s multi-threaded capabilities (Cinebench R23 multi-core score of 51,731) are less relevant here. Instead, the data suggests that the CPU is not the limiting factor at any resolution, as the FPS drops are consistent with GPU scaling rather than a CPU-imposed cap.

The CPU’s memory bandwidth of 115.2 GB/s over a dual-channel DDR5 interface is ample for feeding the GPU, and the PCIe Gen 5 interface with 20 lanes ensures that the GPU’s data path is not constrained. The measured results show no signs of CPU stalls, as even the 4K Ultra average of 65 FPS is well above playable thresholds, and the 1080p results exceed 200 FPS on most presets. If the CPU were a bottleneck, the scaling from 1080p to 1440p would show a smaller FPS drop than it does, but the data shows a proportional reduction that tracks with pixel count.

GPU Role

The Intel Arc B570 is a mid-range GPU based on the Xe2-HPG architecture, built on a 5 nm process. It features 2,304 shading units, 144 texture mapping units, and 80 render output units, with 18 ray tracing cores. The GPU has 10 GB of GDDR6 memory on a 160-bit bus, providing 380.0 GB/s of bandwidth. Its clock speeds are fixed at 2500 MHz for both base and boost, and its FP32 performance is rated at 11.52 TFLOPS. The GPU’s benchmark scores include a 3DMark Steel Nomad DX12 score of 2,649 and a Passmark G3D score of 14,195, placing it in the 65th percentile of all GPUs. Its average benchmark score is 20,556, which is 0.1% higher than the NVIDIA GeForce RTX 3070 Mobile and 0.4% higher than the NVIDIA Quadro M4000M.

In Roblox, the GPU’s role is clearly dominant at higher resolutions. The 4K Ultra result of 65 FPS is the lowest measured, and the 4K High result of 80 FPS is not far behind. This indicates that the GPU is the limiting component when pixel count is high, as the 10 GB VRAM and 380.0 GB/s bandwidth are sufficient for the game’s textures but the shading units are pushed to their limit. The GPU’s 11.52 TFLOPS of FP32 performance is a modest figure, and the data shows that it is the primary constraint at 4K.

The GPU’s VRAM capacity and bandwidth also play a role in the Medium preset results. At 4K Medium, the average is 90 FPS, which is 10 FPS higher than 4K High. This suggests that the Medium preset reduces the GPU’s workload enough to gain a noticeable performance improvement. The 10 GB VRAM is likely not a limiting factor in Roblox, as the game’s textures are not exceptionally demanding, but the 160-bit bus width and 380.0 GB/s bandwidth may constrain performance in scenes with high geometry complexity.

The GPU’s memory clock of 2375 MHz (19 Gbps effective) is a fixed value, and the measured FPS data does not show any signs of memory bandwidth throttling. The scaling from 1440p to 4K is consistent, suggesting that the GPU’s compute units are the bottleneck rather than its memory subsystem. The Passmark DirectX 11 score of 118 versus DirectX 12 score of 72 indicates that the GPU performs better in older APIs, which is relevant because Roblox can run on various rendering paths; the higher FPS at lower settings may partly reflect the game’s engine selecting a less demanding API mode.

Settings Recommendations

Based on the measured FPS rows, the best experience depends on the target resolution and the user’s preference for frame rate versus visual quality. At 1080p, the Medium preset offers a strong balance: 239 FPS average with a minimum of 203 FPS, which is well above the refresh rate of most monitors. The High preset at 1080p provides 211 FPS, which is still excellent and likely offers better visual fidelity without a significant perceptual difference. The Ultra preset at 1080p drops to 171 FPS, which is still smooth but represents a 68 FPS reduction from Medium; this trade-off is likely not worth it unless the user prioritizes maximum visual detail.

At 1440p, the Medium preset is again the recommended choice. It delivers 159 FPS average with a minimum of 135 FPS, which is suitable for high-refresh-rate 1440p displays. The High preset at 1440p reaches 141 FPS, which is also playable but with a narrower margin above 120 FPS. The Ultra preset at 1440p falls to 114 FPS, which is still above 60 FPS but may not be ideal for users with 144Hz or 165Hz monitors. The Low preset at 1440p provides 175 FPS, but the visual quality loss is substantial, so Medium is the better compromise.

At 4K, the Medium preset is the only viable option for maintaining a high frame rate. It delivers 90 FPS average with a minimum of 77 FPS, which is above 60 FPS and provides a playable experience. The High preset at 4K drops to 80 FPS, which is still playable but with less headroom for drops. The Ultra preset at 4K averages 65 FPS, which is near the edge of playability for users who prefer a stable 60 FPS cap. For users with 4K displays, the Medium preset offers the best combination of frame rate and visual quality, as the 77 FPS minimum ensures that the experience stays smooth even in demanding scenes.

How This Combo Ranks

The Intel Core Ultra 9 290K Plus with Intel Arc B570 combination ranks 2,405 out of 3,010 tested combos in Roblox. This places it in the lower half of all combinations, which is notable given the CPU’s high performance. The CPU’s percentile rank is 96th overall, but the GPU’s percentile rank is 65th, meaning the GPU is the weaker link in this pairing. The combo’s ranking suggests that while the CPU is top-tier, the GPU’s mid-range performance holds the combination back in a game that becomes GPU-bound at higher resolutions.

The ranking also reflects the fact that Roblox is not a demanding game by modern standards, so even lower-tier GPUs can achieve high frame rates at 1080p. The combo’s rank of 2,405 out of 3,010 indicates that there are many combinations with better price-to-performance or more balanced specs that achieve higher FPS in this title. However, the measured FPS data shows that this combo is far from inadequate—it exceeds 200 FPS at 1080p on multiple presets and stays above 60 FPS even at 4K Ultra. The ranking is likely influenced by the GPU’s 65th percentile positioning, which is below the CPU’s 96th percentile, creating an imbalance that reduces the overall score.

Measured FPS Breakdown

At 1080p, the measured results are as follows: Low preset averages 262 FPS, Medium averages 239 FPS with a minimum of 203 and a maximum of 275, High averages 211 FPS, and Ultra averages 171 FPS. The spread from Low to Ultra is 91 FPS, with the largest single drop occurring between High and Ultra (40 FPS).

At 1440p, the results are: Low averages 175 FPS, Medium averages 159 FPS with a minimum of 135 and a maximum of 183, High averages 141 FPS, and Ultra averages 114 FPS. The spread from Low to Ultra is 61 FPS, with the largest drop between High and Ultra (27 FPS).

At 4K, the results are: Low averages 99 FPS, Medium averages 90 FPS with a minimum of 77 and a maximum of 104, High averages 80 FPS, and Ultra averages 65 FPS. The spread from Low to Ultra is 34 FPS, with the largest drop between High and Ultra (15 FPS).

The data shows that the gap between Low and Ultra narrows as resolution increases, from 91 FPS at 1080p to 61 FPS at 1440p and 34 FPS at 4K. This indicates that the GPU’s workload becomes more uniform across presets at higher resolutions, as the pixel fill rate dominates the performance cost.
