Roblox

The Intel Core i5-14600KF paired with the Intel Arc B580 delivers a robust Roblox experience, with measured frame rates that range from a 73 FPS average at 4K Ultra to a 297 FPS average at 1080p Low. The data places this combination at rank 2777 out of 3711 tested combos for this game, indicating a mid-pack standing that is heavily influenced by the GPU's performance profile. Across all tested resolutions, the Arc B580 shows a clear pattern of scaling, suggesting that while the CPU provides ample headroom, the graphics card becomes the primary determinant of frame rates at higher settings and resolutions.

Resolution Scaling

The measured FPS data reveals a consistent and significant drop as resolution increases from 1920x1080 to 3840x2160. At High settings, the average frame rate falls from 239 FPS at 1080p to 160 FPS at 1440p, and finally to 90 FPS at 4K. This represents a 62% reduction in frame rate from 1080p to 4K, a substantial decline that points directly to the GPU as the limiting component. The pattern is similar across all settings presets, with the drop from 1080p to 4K being 62% at High, 62% at Low (297 to 112 FPS), 62% at Medium (270 to 102 FPS), and 62% at Ultra (194 to 73 FPS). This uniformity across settings is telling—it suggests that the resolution scaling is not being mitigated by lower graphical loads, which would typically allow the CPU to become more of a factor.

The consistency of this 62% reduction across every preset strongly implies that the Intel Arc B580’s rendering pipeline is the bottleneck. If the CPU were the limiting factor, we would expect to see a smaller percentage drop at lower settings where the GPU has less work to do, because the CPU would be struggling to feed frames at any resolution. Instead, the frame rate scales almost perfectly with the pixel count, which is the classic signature of a GPU-bound scenario. At 1080p Low, the 297 FPS average is high, but the fact that it drops to 112 FPS at 4K Low—a 62% decrease—indicates that even at the lowest settings, the GPU is still the primary constraint. The Core i5-14600KF, with its strong single-threaded performance (as evidenced by a Cinebench R23 single-core score of 4594), is clearly capable of keeping up with the Arc B580’s output at these resolutions.

Interestingly, the Medium preset at each resolution provides the only rows with min and max FPS data. At 1080p Medium, the average is 270 FPS with a min of 230 and max of 311. At 1440p Medium, the average drops to 180 FPS with a min of 153 and max of 207. At 4K Medium, the average is 102 FPS with a min of 87 and max of 117. The relative stability of these ranges, particularly the narrow gap between min and max at 4K (87 to 117, a 34% spread) compared to 1080p (230 to 311, a 35% spread), suggests that the GPU is consistently delivering frames without major stutters, even as the resolution increases. This further reinforces that the Arc B580 is the bottleneck, as its workload scales directly with pixel count, and it appears to handle that load predictably.

GPU Role

The Intel Arc B580 is built on the Xe2-HPG architecture and features 12 GB of GDDR6 memory on a 192-bit bus, providing a memory bandwidth of 456.0 GB/s. The GPU operates at a base and boost clock of 2670 MHz, with a memory clock of 2375 MHz (19 Gbps effective). These specifications contribute to a pixel rate of 213.6 GPixel/s and a texture rate of 427.2 GTexel/s, with FP32 performance rated at 13.67 TFLOPS. The 12 GB VRAM capacity is ample for Roblox, a sandbox game that does not typically demand high memory capacity, and the 456.0 GB/s bandwidth ensures that texture streaming and asset loading are not bottlenecks at the tested resolutions.

In the context of Roblox’s measured performance, the Arc B580’s role is clearly that of the primary performance limiter. The benchmark results show the GPU has a Passmark G3D score of 15748 and a 3DMark Steel Nomad DX12 score of 3068, placing it at the 68th percentile among all GPUs. Its nearest rivals in average benchmark score include the AMD Radeon RX 580 2048SP (deltaPct -0.2), NVIDIA GeForce RTX 2080 (deltaPct 0.6), NVIDIA GeForce RTX 3080 (deltaPct -0.7), and NVIDIA P106-100 (deltaPct -1). These small delta percentages, all within 1% of the Arc B580’s average score, indicate that the GPU’s raw compute performance is competitive with those cards, yet in Roblox, the measured FPS suggests that the GPU’s rendering capabilities are the ceiling.

The VRAM and clock behavior are particularly relevant at 4K resolution. At 3840x2160 Ultra, the average FPS falls to 73, which is the lowest measured in the dataset. This is not due to a lack of VRAM—12 GB is sufficient for Roblox’s relatively simple textures—but rather due to the GPU’s shading units (2560) and ROPs (80) being tasked with filling more pixels. The boost clock of 2670 MHz is consistent across all loads, as the base and boost clocks are identical, which means the GPU does not have additional headroom to mitigate the increased pixel workload at higher resolutions. This fixed clock behavior, combined with the 13.67 TFLOPS FP32 throughput, explains why the frame rate scales so predictably with resolution.

How This Combo Ranks

The combo’s rank in Roblox is 2777 out of 3711 tested combinations, placing it in the 25th percentile of all tested systems. This is a surprisingly low rank given the individual components’ benchmark standings—the Core i5-14600KF is at the 90th percentile among all CPUs, and the Arc B580 is at the 68th percentile among GPUs. The discrepancy suggests that Roblox’s performance profile does not align well with this hardware pairing, likely because the game’s rendering demands favor GPUs with different architectural strengths than what the Arc B580 offers.

Looking at the CPU’s nearest rivals, the Core i5-14600KF has an average benchmark score of 49394, which is 0.3% higher than the AMD Ryzen 9 7900 (49228), 0.4% higher than the AMD Ryzen 7 PRO 5755G (49196), and 0.8% higher than the Intel Core Ultra 5 245 (48995). It trails the AMD Ryzen AI Max+ 388 by 0.8% (49796). These are all extremely close scores, indicating that the CPU is competitive with top-tier alternatives. However, this does not translate to a high combo rank in Roblox, which implies that the game is not heavily CPU-bound for this pairing.

The GPU’s nearest rivals show a similar pattern of close scores, with the Arc B580’s average benchmark score of 23021 being within 1% of the AMD Radeon RX 580 2048SP (23061), NVIDIA GeForce RTX 2080 (22895), NVIDIA GeForce RTX 3080 (23172), and NVIDIA P106-100 (23249). Despite this parity in synthetic benchmarks, the combo’s rank in Roblox suggests that the game may not utilize the Arc B580’s architectural features effectively. The rank of 2777 out of 3711 means that 934 other combos performed better, and given the CPU’s high percentile, the GPU is the most likely cause of this lower ranking. This is a case where synthetic GPU benchmarks do not fully predict in-game performance, particularly in a title like Roblox that has unique rendering characteristics.

Measured FPS Breakdown

At 1920x1080, the measured averages are 239 FPS at High, 297 FPS at Low, 270 FPS at Medium, and 194 FPS at Ultra. The Medium preset provides min and max values of 230 and 311 FPS, respectively. This resolution shows the highest frame rates, with the Low preset exceeding 290 FPS, indicating that the GPU is not heavily taxed at this pixel count. The spread between High (239) and Ultra (194) is 45 FPS, and the jump from Ultra to Medium is 76 FPS, suggesting that the Ultra preset imposes a notable performance penalty.

At 2560x1440, the averages drop to 160 FPS at High, 198 FPS at Low, 180 FPS at Medium, and 129 FPS at Ultra. The Medium preset shows min and max of 153 and 207 FPS. The reduction from 1080p is consistent, with High falling by 79 FPS (33%), Low by 99 FPS (33%), Medium by 90 FPS (33%), and Ultra by 65 FPS (34%). This uniform percentage drop across settings at 1440p mirrors the pattern seen at 4K and reinforces the GPU-bound nature of the performance.

At 3840x2160, the averages are 90 FPS at High, 112 FPS at Low, 102 FPS at Medium, and 73 FPS at Ultra. The Medium preset records min and max of 87 and 117 FPS. The drop from 1440p is again roughly 44% across all settings (High: 160 to 90, Low: 198 to 112, Medium: 180 to 102, Ultra: 129 to 73). This consistent scaling from 1080p to 1440p to 4K is a clear indicator that the GPU’s pixel throughput is the limiting factor, as the frame rate decreases proportionally with the increase in pixel count.

Settings Recommendations

Based on the measured FPS data, the Medium preset offers the most balanced experience across all resolutions, as it is the only preset with complete min and max data, indicating stable frame delivery. At 1080p Medium, the average is 270 FPS with a min of 230, ensuring smooth gameplay on high-refresh-rate displays. At 1440p Medium, the average is 180 FPS with a min of 153, which remains well above the 144 Hz threshold for most monitors. Even at 4K Medium, the average is 102 FPS with a min of 87, which is playable for a sandbox game like Roblox, though it may not fully saturate a 120 Hz display.

For users prioritizing maximum frame rates, the Low preset at 1080p delivers 297 FPS, which is the highest measured value in the dataset. However, the visual quality trade-off may not be worth it, as the jump from Low to Medium at 1080p is only a 27 FPS reduction (297 to 270), while providing better visuals. At 1440p, the Low preset’s 198 FPS is 18 FPS higher than Medium’s 180, and at 4K, Low’s 112 FPS is only 10 FPS higher than Medium’s 102. In all cases, the Medium preset offers a better balance of performance and visual fidelity, with only a modest FPS cost compared to Low.

The Ultra preset is the most demanding, with averages of 194 FPS at 1080p, 129 FPS at 1440p, and 73 FPS at 4K. These are all playable, but the frame rate drops are significant compared to Medium. At 1080p, Ultra is 76 FPS lower than Medium (194 vs 270), at 1440p it is 51 FPS lower (129 vs 180), and at 4K it is 29 FPS lower (73 vs 102). Given that Roblox is a sandbox game where responsiveness matters, the Medium preset appears to be the sweet spot, as it maintains high average FPS and consistent minimums without the steep performance cost of Ultra.

CPU Role

The Intel Core i5-14600KF features 14 cores and 20 threads, with a base clock of 3.50 GHz and a boost clock of 5.30 GHz. It has a 24 MB shared L3 cache and 2 MB L2 cache per core, with 80 KB L1 cache per core. The CPU’s benchmark scores are strong, with a Cinebench R23 multi-core score of 32544 and single-core score of 4594, as well as a Geekbench multi-core score of 17085 and single-core score of 2445. These scores place the CPU at the 90th percentile among all CPUs, indicating it is a high-performance processor.

In the context of Roblox, the CPU’s role appears to be secondary to the GPU, as the resolution scaling data shows a consistent 62% FPS drop from 1080p to 4K across all settings. If the CPU were the bottleneck, we would expect to see a smaller FPS drop at lower settings, where the GPU has less work, because the CPU would be limiting frame generation. Instead, the frame rates scale directly with pixel count, which is the opposite of a CPU-bound scenario. The CPU’s high single-threaded performance, as evidenced by the Cinebench R23 single-core score of 4594, is more than sufficient to handle Roblox’s game logic and physics, which are typically single-threaded.

The CPU’s nearest rivals all have average benchmark scores within 1% of the i5-14600KF, with the AMD Ryzen 9 7900 at 49228 (deltaPct 0.3), AMD Ryzen 7 PRO 5755G at 49196 (deltaPct 0.4), and Intel Core Ultra 5 245 at 48995 (deltaPct 0.8). The AMD Ryzen AI Max+ 388 is slightly ahead at 49796 (deltaPct -0.8). This indicates that the i5-14600KF is competitive with other high-end CPUs, yet the combo’s rank of 2777 out of 3711 in Roblox suggests that the CPU is not the limiting factor. The measured FPS data, with its uniform resolution scaling, confirms that the Arc B580 is the component that determines performance, while the i5-14600KF provides ample headroom to avoid constraining the GPU at any tested resolution or settings level.
