Elkhart Lake [1]. 

Based on a 10 nm manufacturing process, the Elkhart Lake SoC uses Tremont microarchitectures (Atom) [2] and features Gen 11 graphics similar to the Ice Lake processors [3]. Intel’s Gen 11 solution offers 64 execution units, and it has managed over 1 TFLOP in GPU performance [4]. This can be compared with the Nvidia GeForce GT 1030 which offered a peak throughput of 0.94 TFLOPs [5]. Code has already been added in the Linux mainline kernel [6] suggesting a possible Computex announcement and mid to late 2019 availability [7].
