Yesterday was our first look at the Intel Panther Lake Linux performance with the Core Ultra X7 358H and focused on the CPU performance. In today’s benchmarking is a look at the very exciting Xe3 graphics found with the top-tier Panther Lake models: the Arc B390 Graphics with 12 Xe cores.<\/p>\n

\n

The Intel Core Ultra X7 358H features the Arc B390 GPU with 12 Xe cores and up to 2.5GHz maximum graphics frequency. On the display side is eDP 1.5, DP 2.1, and HDMI 2.1 support with the ability to drive up to an 8K @ 60 resolution and up to four total displays.<\/p>\n

\"Panther<\/p>\n

The Xe3 graphics with Panther Lake are quite exciting as previously detailed. The Panther Lake graphics on Linux are in good shape with Linux 6.18+ and Mesa 25.3+ but ideally for best support for new hardware to always be using the latest code, which for the moment is Linux 6.19 and Mesa 26.0+. Plus with Linux 6.19 for the MSI Prestige 14 laptop is working WiFi and audio anyhow. Make sure you have a recent linux-firmware package installed on your system too for recent Intel GuC firmware for the Xe3 graphics.<\/p>\n

\"Intel<\/p>\n

While the OpenGL and Vulkan acceleration with Panther Lake were working with my testing on Linux 6.19 and Mesa 26.0-devel, at first I was struggling to see any performance uplift over Lunar Lake Xe2 graphics in my testing. A very frustrating experience with minimal gains over Lunar Lake. Intel recommended testing with the “performance” platform profile while all the other laptops were in the default \/ out-of-the-box “balanced” mode. At first I was told between the balanced mode on Microsoft Windows and balanced mode on Linux there can be up to a 15 Watt difference in the PL1 state. Then I was told the power limits were the same under Windows and Linux for this laptop, but that MSI programmed their balanced defaults lower than Intel recommends. Intel expects their OEMs to have higher PL1 minimum values for balanced mode but MSI set it lower at 15 Watts min and 30 Watts max for at least this laptop model….<\/p>\n
