   1 # RISC-V 3D GPU / CPU / VPU
   2
   3 Note: this is a **hybrid** CPU, VPU and GPU.  It is not, as many news articles
   4 are implying, a "dedicated exclusive GPU".  The option exists to **create**
   5 a stand-alone GPU product.  It is being *designed* to be a **complete**
   6 all-in-one processor (System-on-a-Chip).

   8 We seek investors, sponsors, engineers and potential customers, who are
   9 interested in the creation and use of an entirely libre low-power mobile
  10 class system-on-a-chip.  Comparative benchmark performance, pincount and
  11 price is the Allwinner A64, except that the power budget target is 2.5 watts
  12 in a 16x16mm 320 to 360 pin 0.8mm FBGA package.
