GPU Role

The Intel Arc B390 is an integrated-class GPU built on Intel's Xe3-LPG architecture with a 3 nm process node. It features 1536 shading units, 48 texture mapping units, and 24 raster output units. The GPU operates with a base clock of 300 MHz and a boost clock of 2500 MHz. Its pixel rate is 60.00 GPixel/s and its texture rate is 120.0 GTexel/s, with FP32 performance rated at 7.680 TFLOPS.

The GPU's memory configuration is entirely system-shared, meaning it draws from the same DDR4 memory pool as the CPU. This is a critical factor for Roblox performance, as the game's rendering demands will compete with the CPU for memory bandwidth. The system-dependent bandwidth means that actual performance can vary based on the memory configuration of the host system.

The Arc B390's role in Roblox is substantial. The measured data shows that the GPU is the primary driver of frame rate differences across settings. At 1080p, moving from Low to Ultra drops the average FPS from 171 to 111, a 35% reduction. This scaling pattern indicates that the GPU's rendering workload is the limiting factor when settings are increased.

The GPU's 9th percentile ranking among all GPUs (percentileVsAllGpus: 9) suggests it is a modest performer. However, Roblox is not a demanding title, and the Arc B390 manages to deliver playable frame rates even at 4K Ultra, with an average of 42 FPS. The 12 ray tracing cores and DirectX 12 Ultimate support indicate modern feature support, though the game's actual usage of these features is not specified in the measured data.

Resolution Scaling

The frame rate drop from 1080p to 4K is significant and reveals the GPU's workload scaling. At High settings, the average FPS drops from 137 at 1080p to 92 at 1440p, then to 52 at 4K. This is a 32.8% drop from 1080p to 1440p, and a 62.0% drop from 1080p to 4K. The scaling is close to linear with pixel count, suggesting the GPU is the primary bottleneck at higher resolutions.

At Low settings, the drop is from 171 FPS at 1080p to 114 FPS at 1440p, and then to 64 FPS at 4K. The percentage drops are 33.3% and 62.6% respectively. This consistent scaling pattern across settings indicates that the Arc B390's rendering throughput is the limiting component, rather than the CPU.

Medium settings show a similar trend: 155 FPS at 1080p, 104 FPS at 1440p, and 59 FPS at 4K. The drop from 1080p to 1440p is 32.9%, and from 1080p to 4K is 61.9%. Ultra settings produce 111 FPS at 1080p, 74 FPS at 1440p, and 42 FPS at 4K, with drops of 33.3% and 62.2% respectively.

The uniformity of these percentage drops across all settings is notable. It strongly suggests that the limiting component is the GPU's fill rate and shading capacity, which scale directly with resolution. The CPU's role appears minimal in this scaling, as the consistent percentage drops indicate the GPU is saturated at all resolution and settings combinations.

The 4K Ultra result of 42 FPS is the lowest measured average, but it remains playable for a sandbox game. The 4K Low result of 64 FPS shows that even at the highest resolution, reducing settings can yield a smooth experience. For users targeting 60 FPS at 4K, Medium settings at 59 FPS are borderline, while Low settings at 64 FPS are safely above the threshold.

Settings Recommendations

The measured data provides clear guidance for optimal settings at each resolution. At 1080p, High settings deliver 137 FPS, which is well above the 60 FPS threshold and only 20% below the Low setting's 171 FPS. The jump from High to Ultra costs 26 FPS (137 to 111), making High the best balance for most users at this resolution.

At 1440p, High settings produce 92 FPS, which is above the 60 FPS threshold and 18 FPS higher than Ultra's 74 FPS. Medium settings at 104 FPS offer a 12 FPS improvement over High, but the visual quality difference may not justify the change for most users. For those prioritizing frame rate, Low at 114 FPS is the maximum, but High is recommended for the best visual quality while maintaining smooth gameplay.

At 4K, the situation changes. High settings drop to 52 FPS, below the 60 FPS threshold. Medium settings at 59 FPS are just below 60, while Low settings at 64 FPS are the only 4K option that exceeds 60 FPS. For users who prefer visual quality over frame rate, Medium at 59 FPS is acceptable, but Low at 64 FPS is the only 4K setting that guarantees a 60 FPS experience.

The data supports a clear recommendation: at 1080p and 1440p, High settings offer the best experience, balancing visual quality with frame rates that are 137 FPS and 92 FPS respectively. At 4K, Low settings are recommended for smooth gameplay, while Medium is acceptable for those who prioritize quality over the 60 FPS threshold.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are as follows: Low produces 171 FPS, Medium produces 155 FPS with a minimum of 132 and maximum of 179, High produces 137 FPS, and Ultra produces 111 FPS. The spread from Low to Ultra is 60 FPS, representing a 35% performance difference between the lowest and highest settings.

At 2560x1440, the average FPS values are: Low at 114, Medium at 104 with a minimum of 88 and maximum of 119, High at 92, and Ultra at 74. The spread from Low to Ultra is 40 FPS, a 35% difference. The minimum FPS for Medium at 1440p is 88, which is still above the 60 FPS threshold.

At 3840x2160, the average FPS values are: Low at 64, Medium at 59 with a minimum of 50 and maximum of 67, High at 52, and Ultra at 42. The spread from Low to Ultra is 22 FPS, a 34% difference. The minimum FPS for Medium at 4K is 50, which is below the 60 FPS threshold, indicating potential frame drops in demanding scenes.

The Medium settings provide the only rows with both minimum and maximum FPS data. At 1080p, Medium averages 155 FPS with a 132-179 range. At 1440p, Medium averages 104 FPS with an 88-119 range. At 4K, Medium averages 59 FPS with a 50-67 range. The consistency of the spread (approximately 47 FPS at 1080p, 31 FPS at 1440p, and 17 FPS at 4K) reflects the GPU's workload scaling.

The data shows a consistent pattern: each resolution step down halves the frame rate approximately, and each settings step reduces performance by roughly 10-20 FPS depending on resolution. The 4K Ultra result of 42 FPS is the lowest measured value, while the 1080p Low result of 171 FPS is the highest.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor from the Core 10th Gen series, built on the Comet Lake architecture with a 14 nm process node. It operates at a base clock of 2.90 GHz and a boost clock of 4.30 GHz, with a 65 W TDP. The CPU supports DDR4 memory with dual-channel configuration and a memory bandwidth of 42.7 GB/s.

The CPU's cache hierarchy includes 64 KB of L1 cache per core, 256 KB of L2 cache per core, and 12 MB of shared L3 cache. The processor has a 68th percentile ranking among all CPUs, with an average benchmark score of 14185. Its nearest rivals in synthetic benchmarks are the Intel Xeon 6756E (score 14163, 0.2% slower), the Intel Core 7 160UL (score 14232, 0.3% faster), the AMD EPYC 7552 (score 14115, 0.5% slower), and the AMD Ryzen 3 7320C (score 14277, 0.6% faster).

In Roblox, the CPU's role is less prominent than the GPU's. The measured FPS data shows consistent scaling patterns across resolutions and settings, which is characteristic of a GPU-bound scenario. However, the CPU's 6 cores and 12 threads provide ample processing power for the game's physics and scripting workloads, which are common in sandbox titles.

The CPU's single-thread performance is measured at 688 in 3DMark single-thread, 2541 in PassMark single-thread, and 1451 in Cinebench R23 single-core. These scores indicate that the i5-10400F's per-core performance is adequate for Roblox's typically single-threaded game logic. The multi-threaded scores (4735 in 3DMark max threads, 10283 in Cinebench R23 multi-core, 12115 in PassMark multi-thread) show that the CPU has headroom for background tasks while gaming.

The CPU's memory bandwidth of 42.7 GB/s is shared with the Arc B390's system-shared memory, which could be a bottleneck in memory-intensive scenes. However, the measured FPS data does not indicate any CPU-related stuttering or frame drops, as the minimum FPS values for Medium settings remain relatively consistent with the averages.

How This Combo Ranks

The combination of the Intel Core i5-10400F and Intel Arc B390 ranks 3289 out of 3711 tested combos for Roblox, placing it in the 11th percentile of all tested configurations. This is a low ranking, indicating that most other CPU-GPU combinations tested for this game deliver higher frame rates.

The ranking is primarily driven by the GPU's modest performance. The Arc B390's 9th percentile ranking among all GPUs (percentileVsAllGpus: 9) is significantly lower than the CPU's 68th percentile ranking. This suggests that the GPU is the limiting factor in this combo, and that the CPU has more performance headroom than the GPU can utilize.

Despite the low combo ranking, the measured FPS data shows that this configuration is playable across all tested settings and resolutions. The lowest measured average is 42 FPS at 4K Ultra, which is still above the 30 FPS minimum for playability. At 1080p, which is the most common gaming resolution, the combo delivers between 111 FPS (Ultra) and 171 FPS (Low), all of which are well above the 60 FPS threshold.

The combo's ranking of 3289 out of 3711 means that 422 other combos performed worse. This places the configuration in the bottom 12% of tested combos. For a game like Roblox, which is not graphically demanding, this ranking reflects the Arc B390's limited rendering capability relative to discrete GPUs.

The data suggests that users with this combo should prioritize lower resolutions and settings to achieve the best experience. At 1080p High, the combo delivers 137 FPS, which is a solid experience for a sandbox game. At 4K, users must drop to Low settings to maintain 60 FPS, which is the practical limit for this configuration.

The CPU's strong benchmark scores relative to its rivals (within 0.6% of the nearest competitors) indicate that the i5-10400F is not the bottleneck in this combo. The GPU's low percentile ranking is the primary reason for the combo's low overall rank in Roblox.
