The board with the CPU, GPU, RAM, and CPU-Board#eMMC which detaches from the Mainboard. Depending on various commercial and technical considerations, new CPU boards may become available to upgrade existing Pyras.

CPU

Main Article: CPU

The OMAP5 (OMAP5432) is the SoC (System on Chip) of the Pyra. It's designed by Texas Instruments and fabricated by UMC on their 28LP process. It resides on the CPU-Board, with these specifications:

  • 2x ARM Cortex-A15 @ 1.5Ghz with NEON SIMD
  • 2x ARM Cortex-M4

GPU

Main Article: GPU

This is on the CPU-Board, as part of the OMAP5 SoC, so has a chance of being upgraded in the future but it cannot be changed separately to the CPU. Unlike a discrete GPU, each block reads/writes main system memory and final video output is done by the TI DISPC display controller block.

RAM

Main Article: RAM

Dual Channel PC DDR3L 532MHz:

  • 4 Ram-Chips on the CPU-Board at 8GBits density means 4GiB total, confirmed[1][2]

eMMC

Main Article: Storage

The undecided amount of eMMC storage is also on the CPU-Board.
