It features NEC's first multi-core System on a Chip vector processor design,[1] with four cores.
The SX-ACE runs at 1 GHz, has peak performance of 64 GFLOPS per core, and has 64 gigabytes per second of memory bandwidth per core.
Four cores make up a shared-memory node, and 64 nodes can fit in a rack for a total performance of 16 TFLOPS per rack.
