# Roblox with Intel Core i9-14900K + Intel Arc B390

The pairing of Intel's flagship 14th-generation desktop processor with an integrated-class Arc GPU creates an unusual bottleneck profile in Roblox. The measured data shows a system where the CPU is dramatically overqualified while the GPU sits near the bottom of the performance percentile, resulting in a combo that ranks 2661 out of 3010 tested configurations. This analysis examines how the frame rates scale across resolutions and settings, what each component contributes, and where the practical limits of this combination lie.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a GPU-bound system with clear limitations. At 1920x1080 with Low settings, the combo delivers 171 FPS average. Moving to 2560x1440 at the same Low preset drops the average to 114 FPS, a 33% reduction. Pushing further to 3840x2160 yields only 64 FPS, which represents a 63% drop from the 1080p figure. This steep decline indicates that the Intel Arc B390's rendering capabilities are the primary constraint as pixel count rises.

The scaling pattern across all settings tells a consistent story. At High settings, the averages are 137 FPS at 1080p, 92 FPS at 1440p, and 52 FPS at 4K. The gap between 1080p and 1440p is 45 FPS, while the gap between 1440p and 4K is 40 FPS. This roughly linear degradation suggests the GPU is saturated at every resolution, with no hidden CPU bottleneck masking the scaling behavior. The data implies that this system is playable at 1080p but struggles to maintain smooth frame rates at 4K, particularly at higher quality presets.

The Medium preset provides the only rows with min and max FPS data, giving insight into frame time consistency. At 1080p Medium, the range spans from 132 to 179 FPS, a 47 FPS spread around the 155 average. At 1440p Medium, the range tightens to 88-119 FPS around a 104 average. At 4K Medium, the range is 50-67 FPS around a 59 average. The narrowing range at higher resolutions indicates that the GPU becomes more consistently saturated, reducing variance but also lowering peak performance.

What this scaling behavior implies is that the system's performance ceiling in Roblox is fundamentally tied to the Arc B390's fill rate and shading throughput. The CPU, with its 24 cores and 32 threads, is never the limiting factor at any resolution. The question becomes whether the dramatic FPS losses at 4K are acceptable for a game like Roblox, which may not demand high frame rates for competitive play but benefits from smoothness in sandbox creation and exploration.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, manufactured on a 3 nm process. Its specifications reveal a deliberately low-power design: 1536 shading units, 48 texture mapping units, and 24 raster output units. The boost clock reaches 2500 MHz, while the base clock sits at 300 MHz. The memory configuration is entirely system-shared, with bandwidth described as system dependent, meaning the GPU borrows from the CPU's main memory rather than having dedicated VRAM.

This memory architecture is critical for understanding the Roblox results. With no dedicated video memory, the Arc B390 depends on the host system's memory bandwidth and latency. The i9-14900K supports DDR4 and DDR5 in dual-channel configuration, but the actual bandwidth available to the iGPU is not specified in the data. The system-shared memory approach explains why the GPU's 3DMark Steel Nomad DX12 score is only 1482, placing it in the 9th percentile of all GPUs. Its nearest rivals are the NVIDIA GeForce GT 520MX, GeForce 800M, GT 625 OEM, and GT 710 — all legacy entry-level parts.

The GPU's FP32 compute is rated at 7.680 TFLOPS, with FP16 at 15.36 TFLOPS via a 2:1 ratio. For a game like Roblox, which uses simple geometry and lighting models, raw compute may be less relevant than fill rate and memory throughput. The pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s are modest figures that align with the measured FPS results. The 2500 MHz boost clock is respectable for an iGPU, but the low base clock of 300 MHz suggests aggressive power management that may cause frequency fluctuation under sustained load.

The API support is notably modern — DirectX 12 Ultimate (12_2), OpenGL 4.6, and Vulkan 1.4 — with 12 ray tracing cores. However, Roblox does not typically leverage ray tracing, so these features likely have minimal impact on the measured frame rates. The data shows that the GPU's performance in Roblox is consistent with its overall benchmark standing: capable of 1080p gaming at playable frame rates, but not designed for high-resolution or high-fidelity workloads.

CPU Role

The Intel Core i9-14900K represents the opposite end of the performance spectrum from the Arc B390. With 24 cores and 32 threads, this Raptor Lake Refresh part is a desktop powerhouse designed for productivity and high-end gaming. The base clock of 3.20 GHz boosts to 6.00 GHz, and the cache hierarchy includes 80 KB of L1 per core, 2 MB of L2 per core, and 36 MB of shared L3. The 125 W TDP indicates substantial power draw, though the system's overall power envelope is constrained by the GPU's 80 W rating.

The CPU's benchmark scores are exceptional. In Cinebench R23, it achieves 39399.5 multi-core and 2262.5 single-core. Geekbench scores are 21697 multi-core and 2655 single-core. These figures place the i9-14900K in the 95th percentile of all CPUs, with an average benchmark score of 79097. Its nearest rivals are the Intel Core i9-14900KF (0.3% lower score), Intel Core Ultra 9 290HX Plus (0.6% lower), and AMD EPYC 7413 (1.2% lower), while the AMD Ryzen AI Max+ 395 trails by 1.7%.

For Roblox, the CPU's role is primarily single-thread bound. The game's engine typically relies on a few threads for physics, scripting, and world simulation. The i9-14900K's single-core performance — evidenced by the 2262.5 Cinebench R23 single-core score and 4697 Passmark single-thread score — is more than sufficient to feed the GPU at any resolution. The data shows no evidence of CPU bottlenecking: FPS scales consistently with resolution, which would not happen if the CPU were the limiting factor.

The 32 threads and 24 cores are largely irrelevant for Roblox, which likely uses only a fraction of the available parallelism. However, the high boost clock of 6.00 GHz and robust cache design ensure that even a lightly threaded game receives maximum responsiveness. The Passmark physics score of 3140 and integer math score of 210622 suggest that the CPU can handle complex game logic without strain, but these capabilities are not reflected in the measured FPS because the GPU cannot keep pace.

Settings Recommendations

The measured data provides clear guidance on which preset offers the best experience. At 1080p, all settings produce playable frame rates, but the differences are meaningful. Low settings yield 171 FPS, Medium delivers 155 FPS, High achieves 137 FPS, and Ultra drops to 111 FPS. The step from Low to Medium costs only 16 FPS but likely provides substantial visual improvements. The step from Medium to High costs another 18 FPS, and High to Ultra costs 26 FPS. For most users, Medium at 1080p appears to offer the best balance: 155 FPS average with a min of 132 FPS, ensuring smooth gameplay even in demanding scenes.

At 1440p, the recommendation shifts. Low delivers 114 FPS, Medium 104 FPS, High 92 FPS, and Ultra 74 FPS. The Medium preset again offers a strong balance at 104 FPS with a min of 88 FPS, keeping frame times consistent enough for responsive play. High at 92 FPS is still acceptable, but Ultra dips below 75 FPS, which may be noticeable for sensitive players.

At 4K, the options are more constrained. Low delivers 64 FPS, Medium 59 FPS, High 52 FPS, and Ultra 42 FPS. Only Low and Medium maintain averages above 60 FPS, with Medium providing the better visual quality at 59 FPS. High and Ultra should be avoided at this resolution unless visual fidelity takes absolute priority over smoothness. The data suggests that 4K gaming with this combo requires compromising on quality presets, and even then, the experience is marginal.

The optimal experience across all resolutions is Medium. At 1080p it provides high frame rates, at 1440p it balances quality and speed, and at 4K it remains the highest-quality preset that stays near 60 FPS. Users prioritizing maximum smoothness should select Low, which consistently outperforms Medium by 10-16 FPS depending on resolution.

A: The combination ranks 2661 out of 3010 tested combos in Roblox, placing it in the bottom 12% of systems. This reflects the GPU's entry-level positioning despite the CPU's flagship status, as the overall system performance is constrained by the weakest component.

Measured FPS Breakdown

At 3840x2160, the measured averages are: Low 64 FPS, Medium 59 FPS (min 50, max 67), High 52 FPS, and Ultra 42 FPS. The Medium preset is the only one with full min/max data, showing a 17 FPS range that indicates moderate frame time variance. The gap between Low and Ultra is 22 FPS, which is substantial and suggests that the visual quality improvements from Ultra come at a significant performance cost.

At 2560x1440, the averages improve considerably: Low 114 FPS, Medium 104 FPS (min 88, max 119), High 92 FPS, and Ultra 74 FPS. The Medium preset shows a 31 FPS range between min and max, which is wider than at 4K, indicating more variance in frame delivery. The step from Ultra to High is 18 FPS, while the step from High to Medium is 12 FPS, and Medium to Low is 10 FPS. This diminishing returns pattern suggests that the cost of each quality tier decreases as settings get lower.

At 1920x1080, the averages reach their peak: Low 171 FPS, Medium 155 FPS (min 132, max 179), High 137 FPS, and Ultra 111 FPS. The Medium preset shows a 47 FPS range, the widest of any resolution, indicating that at 1080p the system has enough headroom to experience larger frame time fluctuations. The max of 179 FPS approaches the 180 FPS threshold that many displays support, suggesting that the system can drive high refresh rate monitors at lower settings.

The progression across resolutions follows a consistent pattern. For Low settings, FPS drops from 171 to 114 to 64 as resolution increases — a 33% drop from 1080p to 1440p and a 44% drop from 1440p to 4K. For Medium, the drops are 33% and 43% respectively. For High, they are 33% and 43%. For Ultra, they are 33% and 43%. This consistency indicates that the GPU's performance scales predictably with pixel count, with no unexpected cliffs or plateaus.

How This Combo Ranks

The combo rank of 2661 out of 3010 places this system in the lower 11.6% of all tested configurations for Roblox. This low ranking is almost entirely attributable to the Intel Arc B390's GPU performance, which sits in the 9th percentile of all GPUs. The i9-14900K, by contrast, is in the 95th percentile of all CPUs, creating a stark mismatch between the two components.

The data implies that this pairing is fundamentally unbalanced for Roblox. The CPU's capabilities far exceed what the game requires, while the GPU's capabilities fall short of what the game's higher settings demand at higher resolutions. The 3DMark Steel Nomad score of 1482 for the GPU, compared to the CPU's average benchmark score of 79097, illustrates the performance disparity. The GPU's nearest rivals are all from the GT 7xx era or older mobile parts, while the CPU's rivals include current-generation flagship parts like the Core Ultra 9 290HX Plus.

For perspective, the i9-14900K's nearest CPU rivals all have average scores within 1.7% of each other, indicating that the CPU is in a tightly contested performance tier. The GPU's rivals, however, span a 2.7% range at much lower absolute scores, reflecting the entry-level market segment where the Arc B390 competes. This combination of a top-tier CPU with a bottom-tier GPU creates a system that ranks near the bottom of gaming benchmarks despite having one of the best processors available.

The practical implication is that users seeking better Roblox performance should prioritize GPU upgrades over CPU upgrades. The measured FPS data shows no CPU bottleneck at any resolution or setting, meaning that any improvement in frame rates would require a more capable graphics solution. The current combo delivers playable results at 1080p and 1440p but struggles at 4K, which aligns with the GPU's positioning as an integrated solution rather than a discrete gaming card.
