Last decade, Intel's Larrabee project failed to even make an entry into the discrete graphics card market, but the architecture lived on as part of the Xeon Phi series. Now that's coming to an end too as Intel has announced the end of life (EOL) status of the Xeon Phi 7200 series. Customers will be able to place orders until August 9, 2019, with final shipments slated for July 31, 2020.
Intel launched several generations of Xeon Phi over the years, including Knights Ferry, Knights Corner, Knights Landing, Knights Hill (never released), and Knights Mill. The product started off as the Larrabee project, aimed at designing a general purpose x86 compute graphics solution for Intel. We had a first glimpse of the initial architecture way back in 2008, however the graphics part of the project was killed by mid 2010, and the product lived on as a many-core processor with large vector compute units.
After two failed attempts to break into the GPU market, it will be interesting to see how the Xe ends up. The first video cards based on Intel's new discrete graphics architecture are expected next year.
