Process names and nominal limits require their original source context.
This comparison matches 8 sourced fields across 4 specification sections. 6 fields differ. 0 of 16 field values use manufacturer disclosures; remaining values retain their source evidence class. The field publication dates remain attached to their sources. There is no matched measured workload benchmark or current price evidence in this page, so it cannot establish a purchase winner, energy-efficiency winner or total system cost.

Who should consider each?
Use the soc specifications to check the intended integration requirements. For a purchase, add current availability, price, software compatibility and measurements of your workload. The field differences alone do not justify recommending one model.
