The SX-6 multi-node Series has peak vector performance of 9.2 Teraflop/s with only 1024 processors and upto 16 Tbyte of memory.

The SX-6 Series supercomputer inherits CMOS technology and shared memory architecture from its predecessors. It delivers much improved price performance and saves space for installation by implementing one CPU on a single chip.

The SX-6 Series also provides various types of middleware and scientific computing application software, enabling personal computers, UNIX server workstation(s) and the SX-6 Series connected via network to be utilised by a single system image.

The SX-6 Series supercomputer achieves one of the world's highest peak performance of 8Teraflop/s. It has a peak performance of 64 Gigaflop/s and 64 Gigabytes of maximum memory per node; a node consists of maximum of eight CPUs. Configured with up to 128 nodes, the SX-6 Series delivers 12 Teraflop/s of peak performance and up to 16 Terabytes (TB) of memory. This translates to 1.6 times higher speed of operations and as large memory capacity as that on the SX-5.

NEC is also selling the Deskside SX-6i supercomputer that features a special microprocessor for vector computers developed by NEC with a top speed of 8 Gflop/s. So far this speed has been achieved only by big supercomputers. NEC has integrated this processor into a compact deskside casing, reducing the entry price for a vector computer.

The NEC TX 7 server series combines Intel Itanium2 CPU based on IA 64 with NEC's technology in high end computing. Each CPU executes simultaneously 6 instructions. Up to four CPUs can be installed in a single cell. Multiple cells are connected via a high-speed crossbar switch.

The NEC HPC Linux Cluster is a class of rack-mountable IA-32 servers operated as Linux Clusters designed as working tools for scientific and engineering calculations. Whenever the software allows to distribute the calculation over several nodes these Linux Clusters offer large compute power.
