Roblox

Roblox with the AMD Ryzen 9 9900X and Intel Arc B570 delivers a highly playable experience across all tested settings, with performance scaling that clearly identifies the GPU as the primary limiting factor at higher resolutions. The data shows a robust frame rate foundation even at 4K, though the gap between settings narrows as resolution increases, indicating that the CPU has ample headroom to spare.

Resolution Scaling

The measured FPS data reveals a classic resolution scaling curve. At 1080p, the combination of the Ryzen 9 9900X and Arc B570 produces extremely high frame rates across all settings, ranging from 171 FPS at Ultra to 262 FPS at Low. This demonstrates that the CPU is not a bottleneck at this resolution; the 12-core, 24-thread processor with a boost clock of 5.60 GHz provides more than enough processing power to feed the GPU. The scaling from 1080p to 1440p shows a predictable decline, with average frame rates dropping by approximately 33% at Ultra settings (from 171 FPS to 114 FPS) and by about 33% at High settings (from 211 FPS to 141 FPS). This consistent percentage drop suggests a balanced workload shift where both components are still contributing effectively.

The transition from 1440p to 4K (3840x2160) tells a more interesting story. At 4K Ultra, the average FPS falls to 65, a 43% reduction from the 1440p Ultra result of 114 FPS. Similarly, 4K High drops to 80 FPS from 141 FPS at 1440p, a 43% decline. This steeper percentage drop compared to the 1080p-to-1440p transition indicates that the GPU is becoming the dominant constraint. The Arc B570, with its 10 GB of GDDR6 memory on a 160-bit bus and 380.0 GB/s bandwidth, is working harder to fill the increased pixel count at 4K. The data shows that at 4K, the difference between Low and High settings narrows to just 19 FPS (99 FPS vs 80 FPS), whereas at 1080p, the same settings gap spans 51 FPS (262 FPS vs 211 FPS). This compression of performance differences at higher resolutions is a hallmark of GPU-bound scenarios.

The frame rate drop from 1080p to 4K at Medium settings—from 239 FPS to 90 FPS, a 62% reduction—further confirms that the GPU is the limiting factor. The CPU's 3DMark single-thread score of 1286 and multi-thread score of 13929 indicate it can handle the game's logic and physics without issue, but the Arc B570's pixel throughput capabilities, rated at 200.0 GPixel/s, are what ultimately cap performance at higher resolutions. The data suggests that players seeking the highest frame rates should target 1080p, where the combo delivers over 170 FPS even at Ultra settings, while 4K remains viable for those prioritizing visual fidelity over raw frame rates.

GPU Role

The Intel Arc B570, built on the Xe2-HPG architecture and codenamed Battlemage, plays a critical role in determining this combo's performance profile in Roblox. The GPU's 10 GB of GDDR6 memory is more than sufficient for Roblox's demands, as evidenced by the consistent performance across all settings at each resolution. The memory operates at 2375 MHz with an effective speed of 19 Gbps, delivering 380.0 GB/s of bandwidth across a 160-bit bus. These specifications are adequate for the game's texture and geometry loads, though the data shows that the GPU's compute capabilities, rated at 11.52 TFLOPS FP32, become the limiting factor at 4K.

The GPU's clock speeds are uniform, with both base and boost clocks set at 2500 MHz. This consistent clocking means there is no thermal or power-based boost variance to consider; the card operates at a steady state. The 150 W TDP and dual-slot design with a single 8-pin power connector suggest the card is designed for mainstream systems, and the performance data aligns with this positioning. The Arc B570's nearest rival, the Intel Arc A750, shows a deltaPct of -0.1, indicating near-identical average benchmark scores, while the NVIDIA GeForce RTX 3070 Mobile is 0.1% ahead. This places the B570 in a competitive mid-range segment.

In Roblox specifically, the GPU's role is most evident in the 4K results. At 4K Low, the combo achieves 99 FPS, but at 4K Ultra, it drops to 65 FPS—a 34% reduction. This scaling indicates that the GPU's shading units (2304) and texture mapping units (144) are being pushed harder as settings increase. The 80 render output units (ROPs) are responsible for the final pixel output, and at 4K Ultra, their workload is substantial. The measured minimum FPS at 4K Medium is 77, with a maximum of 104, showing that even in demanding scenes, the GPU maintains a playable floor. The data suggests that the Arc B570 is well-matched to the Ryzen 9 9900X for this game, as the CPU never appears to starve the GPU of data, even at 1080p where frame rates exceed 260 FPS.
