The landscape of integrated graphics performance in Intel processors has seen significant transformations from the Gen9 era, featuring the Kaby Lake and Skylake architectures, to the latest advancements with the Xe3-based Arc B390 in the Panther Lake SoCs. This article delves into a comprehensive benchmark comparison across eight generations of Intel processors, using Ubuntu 26.04 with Linux 6.18 kernel and Mesa 26.1-devel. We focus on how integrated GPU (iGPU) performance and power efficiency have changed over the past decade.
A unified open-source Linux driver stack plays a crucial role in this analysis, providing a consistent and fair comparison platform across all processor generations by utilizing identical software environments. This enables us to effectively highlight performance evolutions and present insights into power efficiency improvements over time.
The Arc B390 graphics, powered by the Xe3 architecture in the Panther Lake processors, showcase impressive GPU compute performance. Extensive benchmarks, employing the Intel Compute Runtime 26.05.37020.3 on Linux 6.19, place the Arc B390 head-to-head against prior Intel generations, ranging from Tiger Lake to Lunar Lake, and competition like AMD’s Ryzen AI 9 HX 370. These tests cover OpenCL compute workloads while emphasizing power consumption metrics, highlighting the Arc B390’s prowess in delivering strong performance coupled with efficient energy consumption.
Overall, Intel’s continuous investment in optimizing their integrated graphics solutions is evident in the enhanced performance and power management capabilities achieved with each subsequent generation. This progress fortifies Intel’s position in the competitive landscape of integrated graphics and GPU compute performance.
