Intel has announced the Knight Corner co-processor containing more than 50 cores. It's based on a 22 nm process using the new 3D tri-gate transistor geometry. This device can operate at a sustained 1 Teraflop double floating point rate. This is truly impressive. In 1997 you would have need 9,298 Pentium II Xeon processors filling 72 cabinets to achieve this same performance. Now it requires just 1 PCI slot.
