British chip designer ARM has unveiled a new series of 64-bit microprocessors aimed at the server market.
The ARM Cortex-A50 series of processors is based on the ARMv8 architecture, with two designs slated for initial release. These new chips are the Cortex-A53 and the Cortex-A57. Both chips will feature energy-efficient 64-bit processing technology, as well as support for existing 32-bit processing.
The Cortex-A53 is designed as a high-performance part, while the Cortex-A57 has been designed with power efficiency in mind. ARM also claims that the Cortex-A57 is world's smallest 64-bit processor.
The chips can operate separately, or combined into a ARM big.LITTLE processor combination. In this scenario the Cortex-A53 does the heavy lifting while the Cortex-A57 is used for any low-power applications.
Licensees of the new processor series include AMD, Broadcom, Calxeda, HiSilicon, Samsung and STMicroelectronics.
U.S.-based chip-maker AMD, which has resisted licensing ARM designs until 64-bit processors were available, has already announced plans to manufacture 64-bit server processors based on ARM's Cortex-A50 series designs, beginning in 2014.
According to AMD, these chips will fill a demand for denser sever clusters that pack more computing power into a smaller space. This, in turn, allows server rooms to be more efficient because less cooling is required.
