The AMD Ryzen AI 300 series “Strix Point” CPU will power a new ultraportable notebook model in December. It will have LPDDR5X-8000 memory, which is faster than the chip’s normal LPDDR5-7500. After doing some research, Hoang Anh Phu discovered that AMD had subtly changed the processors’ product pages on its website to include compatibility for the LPDDR5X-8000. According to earlier iterations of these pages that The Wayback Machine was able to acquire, the maximum speed for LPDDR5X was 7500 MT/s.

LPDDR5X speeds are typically not higher than what the processor can handle, but standard DDR5 SO-DIMM speeds stay the same at dual-channel DDR5-5600. It’s important to remember that mainstream and enthusiast-segment gaming notebooks typically use faster DDR5 SO-DIMMs than spec using OEM-level memory overclocking. LPDDR5X-8000 chips are only used by OEMs when the processor formally supports them, as this covert specs update does. The laptop in question is an HP EliteBook X G1a, a 14-inch high-end ultraportable that appears to have overclocked its NPU in addition to using LPDDR5X-8000 with “Strix Point” CPUs. The XDNA 2 NPU should be able to achieve 50 TOPS according to AMD’s specifications, but HP has increased performance by 10%.
