Intel brings Knights Corner to market

Intel officially brings Knights Corner to market, according to HPCwire.

The new products clock in at just over a teraflop, double precision.

The 22nm Knights Corner chips will initially be going into two Xeon Phi products: the 3120A and 5110P, both of which are PCIe cards outfitted with a single coprocessor and several gigabytes of GDDR5 memory.

A pre-production part, the SE10P, is also in circulation, but will not be generally available.

The 3120A delivers 1.003 double precision teraflops with 60 cores (1.053 GHZ), while the 5110P offers a skosh more, at 1.011 teraflops, but does so with just 57 cores that are clocked somewhat higher (1.1 GHz).

The big difference is memory. The 5110P houses 8 GB and delivers 320 GB/sec of peak bandwidth; the 3120A, comes with 6 GB and 240 GB/sec of bandwidth.

The 5110P draws 225 watts at peak load, while the 3120A is rated at 300 watts.

Intel's recommended price is below $2,000 for this part, while the higher memory 5110P is being targeted at $2,649."
