Today, Intel announced that its Xeon Phi processors are finally available to customers. This comes nearly a year after the company's originally-quoted launch date, and seven months after Intel announced that pre-production chips were already in use by select partners. The Xeon Phi processors feature double-precision performance in excess of 3 teraflops along with 8 teraflops of single-precision performance. All Xeon Phi processors incorporate 16GB of on-package MCDRAM memory, which Intel says is five times more power efficient as GDDR5 and offers 500GB/s of sustained memory bandwidth. The MCDRAM can effectively be used as a high-speed cache or as a complimentary addition to the system DDR4 memory.
