Such a comparison must be based on the Motu uta v6.0 benchmark with its Tsunami testbench (see results below), providing a quick and simple way to the expected improvement of overall performances of RFID tags.

Conversely, if area saving is more critical, SESAME uHD library represents the best trade-off between high density and low power consumption. This library, which proudly claims to be the densest library available at 180nm, enables up to 25% area reduction (see figure below).
For RFID chip dominated by its digital area, the overall area saving represents the decisive incentive to opt for SESAME uHD library.
