The Rockchip RK3188 is targeted on tablets rather than phones, but it uses the GLOBALFOUNDRIES’ 28SLP (Super Low Power) process, their equivalent to TSMC’s 28HPM, aimed at mobile products. It is again a quad-core part, this time with ARM A9 CPUs running at 1.6 GHz, and quad-core ARM Mali GPUs rated at 600 MHz.
Chipworks says it's got NEON SIMD.


Does anyone know the revision of the Cortex A9 in this SoC?

I would assume its A9r4 but I can't find the revision information on this SoC anywhere.

I just purchased the JXD 7800b with this chip in it for ~54 USD (probably a scam) and was interested in this intriguing SoC.

This SoC has been in devices practically all year, so it's not bleeding edge (the article you linked to is itself months old). The only product we knew for sure will use Cortex-A9 r4 is Tegra 4i which isn't even out yet. So I don't think the presence of r4 here is a great assumption.

I can confirm that it definitely has NEON. Not having NEON would have been a remarkably poor design decision.

And yeah, that JXD 7800b purchase was almost certainly a scam, what were you thinking? 😛
