    1. Intel Labs really does work on some interesting things. Intel apparently worked on stacked SRAM back in 2007... This was one of the many predecessors of MIC (Xeon Phi), along with Larrabee and Rock Creek. (1/3)

    Polaris clocks at up to 5.7GHz, and has 80 cores in a 10x8 2D Mesh on Intel's 65nm process node. At 0.6V (11W), it could do 310 GFLOPs. At 1.35V (265W), it could do 1.824 TFLOPs. It contains 100 million transistors in 274.54 mm². Each of the tiles in the mesh is 3 mm². (2/3)

      This diagram shows Freya, which is 20 MiB SRAM, 256 KiB/core, stacked below the main chip, with 3200 TSV's. This provides over 1 TB/s of bandwidth to the cores, which is insane for the time. Last but not least, Polaris is eternal. (3/3) Source: en.wikichip.org/wiki/intel/microarchitectures/polaris
