Resolution Scaling

The measured frame rates across the three resolutions reveal a configuration that scales predictably with pixel count, but with a clear inflection point between 1440p and 4K. At 1080p, the AMD Ryzen 7 9700X and Intel Arc B580 combination delivers 237.3 FPS on High settings. Moving to 2560x1440, the same settings produce 158 FPS, a drop of roughly 33%. The transition to 3840x2160 yields 89.1 FPS, which is a 44% reduction from the 1440p figure. This scaling pattern suggests that at 1080p, the system is heavily CPU-bound; the GPU is not the limiting factor. The Ryzen 7 9700X’s high single-thread performance, evidenced by a 3DMark single-thread score of 1280 and a Cinebench R23 single-core score of 4459, is likely feeding the Arc B580 enough data to keep it busy, but the frame ceiling is set by the processor.

The delta between Low and Ultra settings also narrows as resolution increases. At 1080p, the spread is 104.3 FPS, from 294.1 FPS on Low to 189.8 FPS on Ultra. At 1440p, the spread compresses to 68.1 FPS, from 196.5 FPS to 128.4 FPS. At 4K, the spread is just 39.1 FPS, from 113.9 FPS to 74.8 FPS. This tightening is consistent with the GPU becoming the primary bottleneck at higher resolutions. The Arc B580’s raw compute, measured at 13.67 TFLOPS FP32, is being saturated at 4K, making the pixel workload the dominant cost. In contrast, at 1080p, the CPU’s ability to process game logic and draw calls is the constraining factor, which is why lowering settings yields such a large FPS increase.

The data indicates that this pairing is well-balanced for 1440p gaming, where the FPS remains above 128 FPS even on Ultra settings. For 4K, the system is still playable, with 74.8 FPS on Ultra, but the performance headroom is gone. The 89.1 FPS on High at 4K is respectable, but the trend suggests that users targeting 4K should consider the GPU’s position relative to its rivals. The Arc B580 sits just 0.7% behind the NVIDIA GeForce RTX 4060 in average benchmark score, and 1.3% ahead of the RTX 4060 Mobile. This places it in a competitive tier for 1440p, but not a top-tier 4K card.

GPU Role

The Intel Arc B580’s specifications are central to understanding its behavior in Roblox. The GPU is built on the Xe2-HPG architecture and features 2560 shading units, 160 texture mapping units, and 80 render output units. Its 12 GB of GDDR6 memory, running at 2375 MHz (19 Gbps effective) across a 192-bit bus, yields a bandwidth of 456.0 GB/s. This memory configuration is generous for the game’s typical asset sizes, allowing high texture quality without stutter. The base and boost clocks are identical at 2670 MHz, which simplifies performance prediction; the card runs at a constant frequency under load.

The GPU’s position in the benchmark hierarchy is tight. It holds a 66th percentile rank among all GPUs, with an average benchmark score of 23021. Its nearest rival, the AMD Radeon 760M, is just 0.1% behind, making the two effectively identical in aggregate compute. The NVIDIA P106-100 is 0.3% behind, while the RTX 4060 Mobile is 1.3% behind. The RTX 4060 desktop is 0.7% ahead. This clustering means that in a game like Roblox, which is not heavily GPU-bound at lower resolutions, the Arc B580’s performance will be dictated more by driver overhead and CPU interaction than by raw silicon capabilities.

The measured FPS data confirms this. At 4K Ultra, the card produces 74.8 FPS, which is a 21% drop from the 4K High setting (89.1 FPS). This is a relatively modest penalty for enabling Ultra settings, suggesting that the game’s Ultra preset adds effects that are not purely pixel-bound. However, the card’s FP32 throughput of 13.67 TFLOPS is being pushed at this resolution. The texture rate of 427.2 GTexel/s and pixel rate of 213.6 GPixel/s are sufficient for 4K, but the frame rates show that the card is not idle. For users, this means that the Arc B580 is a capable 1440p card, but it will require setting adjustments for a locked 60 FPS experience at 4K. The 12 GB VRAM is a non-issue for Roblox, as the game’s textures are unlikely to exceed this capacity even at maximum settings.

Measured FPS Breakdown

The dataset provides a clear matrix of average FPS across three resolutions and four settings levels. At 1920x1080, the results are as follows: Low yields 294.1 FPS, Medium yields 265.5 FPS, High yields 237.3 FPS, and Ultra yields 189.8 FPS. The progression from Low to Ultra shows a stepwise reduction, with the largest single drop occurring between High and Ultra, a 47.5 FPS decrease. This suggests that the Ultra preset introduces a significant computational load, likely through additional lighting or post-processing effects.

Moving to 2560x1440, the FPS figures are 196.5 (Low), 179.2 (Medium), 158.0 (High), and 128.4 (Ultra). The relative ordering is consistent, but the absolute differences are smaller. The gap between Low and Ultra is 68.1 FPS, which is proportionally similar to the 1080p gap of 104.3 FPS, but the percentage drop from Low to Ultra is 34.7% at 1440p versus 35.5% at 1080p. This indicates that the scaling is nearly uniform across these two resolutions.

At 3840x2160, the performance compresses further: 113.9 FPS (Low), 102.6 FPS (Medium), 89.1 FPS (High), and 74.8 FPS (Ultra). The drop from Low to Ultra is 39.1 FPS, a 34.3% reduction. The consistency of this percentage across all three resolutions is notable. It implies that the game’s settings have a multiplicative, rather than additive, effect on frame time. The 4K results also show that the system never falls below 74.8 FPS, which is above the 60 FPS threshold for smooth play. For the most demanding scenario, 4K Ultra, the system delivers a playable experience, but users seeking higher refresh rates will need to use High or Medium settings.

CPU Role

The AMD Ryzen 7 9700X is a Zen 5 architecture processor, codenamed Granite Ridge, manufactured on a 4 nm process by TSMC. It features 8 cores and 16 threads, with a base clock of 3.80 GHz and a boost clock of 5.50 GHz. The 65 W TDP is modest for a desktop chip, and its memory support is DDR5 in a dual-channel configuration, providing a bandwidth of 89.6 GB/s. The CPU’s cache hierarchy includes 80 KB of L1 per core, 1 MB of L2 per core, and a shared 32 MB L3 cache. This cache structure is critical for a game like Roblox, which often has repetitive draw calls and script execution.

The CPU’s benchmark scores show a clear strength in single-threaded performance. Its Cinebench R23 single-core score is 4459, while its multi-core score is 31588. In 3DMark, the single-thread score is 1280, and the 2-thread score is 2525. These scores indicate that the CPU can handle the game’s main thread efficiently. The 8-core, 16-thread configuration ensures that background tasks and secondary threads do not interfere with the primary game thread. The CPU’s percentile rank is 89th among all CPUs, with an average benchmark score of 36029.

The influence of the CPU is most evident at 1080p. The FPS at 1080p Low (294.1) is nearly double the FPS at 4K Low (113.9), which is a far larger difference than the pixel count alone would suggest. This indicates that at 1080p, the CPU is the limiting factor, and the GPU has headroom. The 3DMark 4-thread score of 4869 and 8-thread score of 8184 suggest that the CPU scales well with thread count, but the game likely relies on fewer threads. The high boost clock of 5.50 GHz is a key contributor to the high single-thread performance, which directly translates to higher FPS in CPU-bound scenarios.

The combination of the Ryzen 7 9700X and Arc B580 results in a rank of 1412 out of 1800 possible combinations in this game. This places the pairing in the 78th percentile of tested combos. The data shows that the CPU is not a bottleneck at 1440p and 4K, where the GPU becomes the limiting factor. However, at 1080p, the CPU’s performance is the primary driver of frame rates. Users with high refresh rate 1080p monitors will benefit from the CPU’s strong single-thread capabilities, while those with 4K displays will be limited by the GPU.
