Most of the ARM cores available today in little single board computers are either A8 or A9 cortex. The ARM A15 CPU cores should be around 40 percent more powerful than an A9 core running at the same clock speed. The A15 CPU can be found in some consumer oriented machines such as the Nexus 10. Most devices with A15 cores are dual core configurations as of mid 2013.
The TI OMAP5432 is a small single board computer that was released in Q2 of 2013. It has a dual core A15 at up to 1.5 GHz, 2GB of DDR3 memory, 4Gb of flash memory, USB 3.0, a SATA port, 10/100 ethernet, HDMI, and a microSD card slot. The HDMI is driven by the OMAP 5 CPU which also has a DSP and also includes various image and video accelerating hardware along with two Cortex M4 microprocessors. The OMAP5432 is released as an Evaluation Module (EVM), so it is not targeted towards end users. We have obtained one of these boards to benchmark the performance of the OMAP5 SoC.
