Intel Arc B390 Panther Lake Generational Performance Since The Gen9 Graphics Era
Vkpeak to demonstrate the Vulkan compute peak potential for different data types showed off the great progress too for Panther Lake. The old Gen9 graphics failed to run vkpeak but even going back to Ice Lake are some magnificent improvements.
When taking the geometric mean of all the benchmarks that ran successfully on all of the hardware from Gen9 graphics to Xe3, here is the geo mean. On a geo mean basis across this mix of OpenGL and Vulkan benchmarks was 11.97x the performance with the Core Ultra X7 358H Panther Lake compared to Core i7 8550U "Whiskey Lake". Seeing around 12x the performance for Intel Xe3 graphics on Panther Lake compared to Gen9 graphics during the 14nm era was quite common across the different Intel iGPU benchmarks.
The power efficiency has evolved a lot too since then though on a performance-per-Watt basis Lunar Lake delivered a more sizable generational jump but still very healthy gains from Lunar Lake to Panther Lake.
That's the look on the graphics side. The big look at CPU performance from Panther Lake all the way to Sandy Bridge or perhaps Nehalem will be wrapped up in the next week or so.
As exciting as these results are for Intel Arc B390, there is even more performance still on the table for Panther Lake. As shown earlier this week in the Windows 11 vs. Linux Panther Lake benchmarks, the Intel Windows driver still holds some nice performance advantages over the Linux driver especially for Vulkan. Hopefully in the coming months the open-source Intel Linux driver will continue to see more performance optimizations for Xe3.
