Breakthrough AES Performance with Intel AES New Instructions

Intel continues to provide leadership in developing instruction-set extensions with the recently released ISA support for the Advanced Encryption Standard (AES). This paper presents the excellent performance of the AES algorithm on the Intel® Core™ i7 Processor Extreme Edition, i7-980X, using the AES New Instructions (AES-NI). Performance results for serial and parallel modes of operation are provided for all key sizes, for variable numbers of cores and threads. These results have been achieved using highly optimized implementations of the AES functions that can achieve ~1.3 cycles/byte on a single-core Intel® Core™ i7 Processor Extreme Edition, i7-980X for AES-128 in parallel modes. The paper also has a brief description of how to code to achieve these results and a reference to the complete source code.
