LG is about to debut its own L9 chipset this September. The L9 will be feature a quad-core ARM processor and a powerful GPU, but the architecture is yet to be announced.
As the number 9 in the name suggests, the L9 might be based on the older ARM Cortex-A9 cores instead of the newer Cortex-A15 architecture. Though as you probably know LG licensed both A9 and A15 ARM architectures, so you never know.
Anyway, the new L9 platform will power a new high-end LG phone set to launch in September. It will pack a True HD-IPS screen (the one we saw on the Optimus 4X HD) and will bring a camera with a resolution of 10 or more megapixels.
