Intel is reportedly mandating OEM integrators of the latest "Panther Lake" SoCs to use LPDDR5X memory starting at 7,467 MT/s and beyond, with an interesting software differentiator between adequate speeds or those below. According to Golden Pig Upgrade, LDDR5X memory running below the 7,467 MT/s threshold will force the software to display a generic mark of "Intel (R) Graphics," while configurations with that exact memory speed or higher will display the full name of "Intel (R) Arc (TM) Graphics B390" or "Intel (R) Arc (TM) Graphics B370" marking in Windows 11 Task Manager. Reportedly, Intel is doing this to stop OEMs from cutting corners with their "Panther Lake" laptop configurations, where they could bundle a lower-speed LDDR5X memory out of the Intel specification.

Without the required memory, Intel's Arc B390/B370 iGPUs would likely be left starving for bandwidth, as the whole SoC is being powered by that memory. At higher speeds, memory can do the data transfer faster, resulting in a boost of the overall system performance, and most importantly, the frame rate that these chips can push out. Especially for single-package systems like "Panther Lake" is, faster memory is a great way to get extra performance boost. Intel's flagship SKUs are advertised as capable of running with LPDDR5X memory at speeds up to 9,600 MT/s, which is where the LPDDR5X technology tops out. Interestingly, there are lots of options from Intel's OEM partners that integrate top-end memory, which is a positive sign for the ecosystem.
