Qualcomm says its Oryon CPU cores have 1% or less of Arm's original technology — cores in Snapdragon X PC chips are almost entirely custom

Qualcomm Snapdragon Summit benchmarks comparing Snapdragon X Elite to Intel Lunar Lake.

The Qualcomm Oryon general-purpose cores found inside Snapdragon X processors are based on Arm's Armv8 instruction set architecture (ISA), but they use very little technology developed by Arm, says Gerard Williams III, one of the lead developers behind Oryon and a variety of Apple's processors.

"One percent or less," said Williams when asked to estimate the amount of Arm technology in the final design developed by Nuvia. The news came in a new report from Reuters.
