The Exynos 5440 quad-core processor, which is rumored to be the chip powering Samsung's Galaxy S4, has been confirmed by the technology giant.
Samsung confirmed the quad-core chip's existence through its Kernel Git webpage. The chip itself is based on the dual-core version found in the Nexus 10 tablet, which it developed for Google.
Production on the Exynos 5450 chipset for the Galaxy S4 has previously been rumored, with the unannounced smartphone itself set to be unveiled during CES, 2013.
According to industry sources, the Samsung Galaxy S4, which is apparently codenamed 'Project J' and due for an April 2013 launch, sports a 5-inch full HD display, a 13MP camera and runs the latest version of Android -- perhaps Key Lime Pie.
Other speculation has suggested the device will be the first (or second) handset in history to feature eight cores.
