Adapteva announces 28nm 64-core Epiphany-IV microprocessor chip

LEXINGTON, USA: Adapteva, a privately-held semiconductor technology start up, released the fourth generation of its Epiphany multicore architecture IP – a 28nm design with 64 independent high-performance RISC cores on a single chip. The latest generation of the Epiphany architecture offers the highest energy efficiency of any floating point processor solution to date, with a ground-breaking 70 GFLOPS/Watt.

“With the launch of the Epiphany architecture in 28nm, we’re able to bring even more computing power to a tiny footprint, without increased energy drain,” said Andreas Olofsson, CEO of Adapteva. “The Epiphany-IV platform demonstrates an immediate path to exceeding DARPA’s 2018 goal of 50 GFLOPS/Watt in high performance computing applications.”

CoreMark benchmarking data shows that the previously released Epiphany-III chip reaches equivalent performance levels of server type microprocessors like the Intel Xeon chips, while consuming less than 2W of peak power. The Epiphany-IV chip will be even more impressive with a 4X performance improvement on CoreMark benchmarks while keeping the power consumption the same as the previous generation. Adapteva’s low-power, high-performance approach will transform the mobile markets by enabling server-level computing local to portable devices such as smartphones and tablets.
