How This Combo Ranks

The combo's rank of 2661 out of 3010 tested combinations indicates it falls in the lower percentile of systems tested for Roblox. This positioning is heavily influenced by the GPU's performance category. The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, designed for mobile or low-power segments. Its percentile rank among all GPUs is 9, meaning it outperforms only 9% of all GPUs in the database. This places it in the company of legacy discrete parts like the NVIDIA GeForce GT 520MX and GeForce 800M, which score 1463 and 1460 respectively, within a 1.3% and 1.5% delta of the Arc B390's 1482 score.

This low GPU standing is counterbalanced by a very strong CPU. The Core i7-12700KF sits in the 85th percentile of all CPUs, with an average benchmark score of 35365. This score is nearly identical to its nearest rivals: the Intel Core i7-13700T (35403, -0.1% delta), the Intel Core 5 213PE (35428, -0.2% delta), the Intel Core i5-13600T (35305, 0.2% delta), and the Intel Core i7-12700K (35287, 0.2% delta). The result is a pairing of a top-tier 12-core processor with an entry-level integrated GPU, which explains the combination's relatively low rank despite excellent CPU potential.

The performance delta between the CPU and GPU is stark. The CPU's multi-threaded capabilities, evidenced by a Cinebench R23 multi-core score of 28838, are far beyond what the Arc B390 can utilize in a game like Roblox. The data suggests the combination's rank is a direct consequence of this imbalance, where the GPU becomes the bottleneck in more demanding scenarios.

Resolution Scaling

The measured FPS data reveals a clear pattern of how the system scales from 1080p to 4K. At 1920x1080, the system delivers a high average FPS across all settings, ranging from 111 FPS on Ultra to 171 FPS on Low. As resolution increases to 2560x1440, the average FPS drops by roughly 30-35% across settings. For instance, High settings go from 137 FPS at 1080p to 92 FPS at 1440p, a 32.8% reduction. At 4K, the drop is much more severe, with High settings falling to 52 FPS, a 62% reduction from the 1080p result.

This scaling pattern indicates a shift in the limiting component. At 1080p, the frame rates are high enough to suggest the CPU is the primary constraint, as the GPU is not being pushed to its limits. The relatively small difference between Low (171 FPS) and Ultra (111 FPS) at 1080p—a 35% spread—further suggests that the CPU is holding back the frame rate, as the GPU should show a larger gap between low and ultra settings at a fixed resolution if it were the bottleneck.

However, the dramatic drop at 4K tells a different story. The difference between 1080p Low (171 FPS) and 4K Low (64 FPS) represents a 62.6% reduction, which is more characteristic of a GPU-bound scenario. The Arc B390, with its system-shared memory and 7.680 TFLOPS of FP32 performance, struggles to maintain frame rates as the pixel count quadruples. At 4K, the GPU becomes the definitive limiting factor, as the CPU's performance headroom cannot compensate for the GPU's rendering limitations.

Measured FPS Breakdown

The data provides a comprehensive view of performance across three resolutions and four settings presets. Starting at 1920x1080, the system achieves its highest frame rates. The Low preset averages 171 FPS, Medium averages 155 FPS, High averages 137 FPS, and Ultra averages 111 FPS. The Medium preset is the only one with full min/max data, showing a range of 132 to 179 FPS, indicating reasonable frame time consistency.

Moving to 2560x1440, the averages are 114 FPS on Low, 104 FPS on Medium, 92 FPS on High, and 74 FPS on Ultra. The Medium preset shows a min of 88 FPS and a max of 119 FPS, a slightly wider relative spread than at 1080p. This resolution still provides playable frame rates, but the scaling from 1080p shows a consistent reduction of about 30-35% across all settings.

At 3840x2160, the system's limitations become apparent. The Low preset averages 64 FPS, Medium averages 59 FPS, High averages 52 FPS, and Ultra drops to 42 FPS. The Medium preset records a minimum of 50 FPS and a maximum of 67 FPS, showing that even the average frame rate is not stable under load. The gap between Low and Ultra at 4K is 22 FPS (34.4% reduction), which is a more pronounced difference than at 1080p, confirming the GPU's increased role as the resolution climbs.

GPU Role

The Intel Arc B390 is an integrated GPU based on the Xe3-LPG architecture, built on a 3 nm process. Its clock speeds are listed as a base of 300 MHz and a boost of 2500 MHz. The GPU has 1536 shading units, 48 TMUs, and 24 ROPs, along with 12 ray tracing cores. Its compute capabilities are rated at 7.680 TFLOPS for FP32 and 15.36 TFLOPS for FP16 (2:1 ratio). The pixel rate is 60.00 GPixel/s and the texture rate is 120.0 GTexel/s.

The most critical aspect of this GPU is its memory configuration. It has no dedicated VRAM; instead, it uses "System Shared" memory for size, type, and bus width, with bandwidth being "System Dependent." This means the GPU's performance is directly tied to the system's memory bandwidth and capacity, which can be a significant bottleneck in games. The data shows this is a mobile-class part, with a TDP of 80 W, no power connectors, and a slot width of IGP, indicating it is designed for portable devices.

In Roblox, the GPU's role becomes more pronounced at higher resolutions. At 1080p, the GPU is not fully utilized, as evidenced by the relatively small FPS differences between settings. However, at 4K, the GPU's limitations are stark. The average FPS at 4K Ultra is 42, which is just above the threshold for playability. The GPU's low percentile ranking (9th) and its proximity to legacy parts like the GeForce GT 710 (1443 score, 2.7% delta) underscore its entry-level positioning. The data suggests that while the GPU can handle Roblox at 1080p and 1440p with playable frame rates, it struggles to maintain smooth performance at 4K, especially on higher settings.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For 1920x1080, all settings provide playable frame rates, with the Low preset offering 171 FPS and the High preset offering 137 FPS. The Ultra preset at 111 FPS is still smooth, but the difference between High and Ultra is 26 FPS (19% reduction). For most users, the High preset at 1080p offers the best balance of visual quality and performance, maintaining an average above 130 FPS.

At 2560x1440, the High preset averages 92 FPS, which is acceptable for most play. The Ultra preset drops to 74 FPS, which is still playable but shows a 19.6% reduction from High. The Medium preset at 104 FPS offers a good middle ground, with a minimum of 88 FPS ensuring most scenes stay above 60 FPS. For 1440p, the Medium preset is recommended as it provides a comfortable margin above 60 FPS while retaining decent visual quality.

At 3840x2160, the situation is more constrained. The Low preset averages 64 FPS, which is just above the 60 FPS target, but the Medium preset drops to 59 FPS and High to 52 FPS. The Ultra preset at 42 FPS is likely too choppy for consistent play. For 4K, the Low preset is the only one that consistently maintains an average above 60 FPS. The data shows that the gap between Low and Medium at 4K is only 5 FPS (7.8% reduction), suggesting the GPU is heavily taxed even at low settings. Therefore, for 4K, the Low preset is the recommended choice.

CPU Role

The Intel Core i7-12700KF is a 12-core, 20-thread processor based on the Alder Lake architecture, built on a 10 nm process. It has a base clock of 3.60 GHz and a boost clock of 5.00 GHz. The CPU's cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and 25 MB of shared L3 cache. It supports DDR4 and DDR5 memory in a dual-channel configuration and has 20 PCIe Gen 4 lanes.

In the context of Roblox, the CPU's performance is more than sufficient. Its benchmark scores are impressive, with a Cinebench R23 multi-core score of 28838 and a single-core score of 4071. The Geekbench multi-core score is 14367, and the single-core score is 2255. These scores place the CPU in the 85th percentile of all CPUs, indicating it is a high-performance part.

The data suggests the CPU is not a bottleneck in this game at lower resolutions. At 1080p, the frame rates are high across all settings, and the difference between Low and Ultra is relatively modest, indicating the CPU is feeding the GPU adequately. The CPU's 20 threads and high boost clock are likely more than enough for Roblox's workload, which is typically not heavily multi-threaded. The single-core performance, as measured by 3DMark single-thread score of 1043, is strong and should ensure smooth gameplay in scenarios where the CPU is the limiting factor.

However, the CPU's capabilities are wasted at 4K, where the GPU's limitations become the primary constraint. The measured FPS drop at 4K is consistent with a GPU-bound scenario, as the CPU's performance headroom cannot overcome the GPU's rendering limits. The pairing of this high-end CPU with an entry-level integrated GPU creates a significant imbalance, but in Roblox's case, it means the CPU will rarely be the cause of low frame rates, except possibly in heavily populated or complex scenes where the game's logic and physics might become more demanding. The CPU's 25 MB of L3 cache and high clock speeds provide ample headroom for such scenarios.
