Over 1 TeraFLOPS on a single chip
GPGPU and cloud computing have been hot topics for the last several years. Intel has shown off several designs like
Single-chip Cloud Compute
r in the past. However, it is
that will be the firm's first commercial product to use the Many Integrated Core (MIC) architecture. The co-processor will be offered as a PCIe add-in board.
The MIC concept is simple: Use architecture specifically designed to process highly parallel workloads, but ensure compatibility with existing x86 programming models and tools.
This would give MIC co-processors the ability to run existing applications without the need to port the code to a new programming environment, theoretically allowing maximum CPU and co-processor performance simultaneously with existing x86 based applications. This would dramatically save time, cost and resources that would otherwise be needed to rewrite them to alternative proprietary languages.
AMD and NVIDIA have been trying to do with their
by enabling support for languages like C++, but Intel wants to challenge them in this potentially lucrative market.
will be manufactured using Intel’s latest 3-D Tri-Gate
P1270 22nm transistor process
and will feature more than 50 cores. Intel demonstrated first silicon of
at the SC11 conference yesterday. The co-processor wowed the crowd by delivering more than 1 TeraFLOPS of double precision floating point performance.
The firm also touted its "commitment to delivering the most efficient and programming-friendly platform for highly parallel applications", and showed off the benefits of the MIC architecture in weather modeling, tomography, protein folding, and advanced materials simulation at its booth.
There is no timeframe on when
will enter production or be available to customers.

The article title marks this as a "CPU". It decidedly is not. a "CPU" is a "
Processing Unit". This thing is a co-processor. it can be programmed to do wide, fast (although I'm thinking a GTX580 would do far wider and far faster) processing, but it
be used as the central processor in a system. It needs a real CPU to operate the system and send it commands. Therefore, this is definitely not a "CPU".

Intel doesn't think so. From their SC11 presentation, various modes:
Native mode: KNF(Knights Ferry) is a
fully networked Linux system.
Offload mode: KNF is an
Cluster mode: parallel application distributed across multiple KNF and hosts using MPI
For flops, enlighten yourself from reading other posts.
