Intel Kills Off Xeon Phi 7200 Coprocessor

9


Intel’s Xeon Phi 7200 Coprocessors, the descendants of Intel’s failed Larrabee GPU project, are apparently being retired. Intel made the announcement in a rather low key manner via a forum post, as spotted by the Linux-loving Phoronix. Posters complained that Intel apparently scrubbed all reference of the coprocessors from its website, along with the MPSS 4.0 software stack. An Intel representative responded:

Intel continually evaluates the markets for our products in order to provide the best possible solutions to our customer’s challenges. As part of this on-going evaluation process Intel has decided to not offer Intel Xeon Phi 7200 Coprocessor (codenamed Knights Landing Coprocessor) products to the market.

  • Given the rapid adoption of Intel Xeon Phi 7200 processors, Intel has decided to not deploy the Knights Landing Coprocessor to the general market.

  • Intel Xeon Phi Processors remain a key element of our solution portfolio for providing customers the most compelling and competitive solutions possible.

The Xeon Phi Knights Landing processors come in two flavors: a socketed LGA 3647 host processor and a PCIe-attached Add-In Card (AIC). Intel designed the Knights Mill products to address a wide variety of AI and HPC workloads.The development isn’t entirely unexpected; Intel predicted during the initial Knights Landing launch that more than 50% of its customers would prefer the host processor variant. The socketed processors have a few notable advantages over the AIC models, such as bootability and the option for integrated 100Gb/s Omni-Path fabric.

Knights Landing was the first product to come to market wielding Intel’s new mesh topology, which connects 72 quad-threaded Silvermont-derived cores into one cohesive unit. The new mesh topology has now filtered down into Intel’s Purley and Skylake-X processors. 

Meanwhile, Intel has its new Knights Mill products coming to market, but Intel has not revealed the core count yet (the slide references the Knights Landing). Tellingly, the Knights Mill family only comes as a host processor, and not in the AIC form factor.

Intel has plenty of options for machine learning tasks, including its Xilinx-derived FPGAs, Nervana ASICs, and Knights Landing host processors. It appears that the company is narrowing its focus to host processors for the Xeon Phi Knights Landing and Mill families, but the statement assures us that Xeon Phi processors remain a key part of Intel’s portfolio. We’ve reached out to Intel for more information and will update as necessary.
