Intel's Xeon Phi lineup, which started as Larrabee. has never seen any commercial success in the market despite big promises from the big blue giant that its programming model would be more productive for developers coming from x86. In the meantime, NVIDIA GPUs have taken over the world of supercomputing, with the latest generation Volta decimating Intel Xeon Phi offerings.

Intel's plan was to release a new generation of Xeon Phi called "Knights Hill", on a 10 nanometer process. However, constant delays ramping up 10 nm, paired with generally low demand for Xeon Phi, forced the company to abandon this project. Now the company announces that they are stopping production for eight currently shipping Xeon Phi models.Affected are Xeon Phi 7210, 7210F, 7230, 7230F, 7250, 7250F, 7290 and 7290F, which are socketed CPUs that go into accelerator designs. The accelerator cards using a graphics card-like form factor were already cancelled a while ago. Interestingly, the change notice mentions "Market demand for the products [...] have shifted to other Intel products"... yeah, well, these products don't exist at Intel. The company has nothing comparable in their lineup, and the only successor I could think of is the GPU project that Raja Koduri and his minions are working on, which is expected not before 2019, probably later.
