Previoulsy, not so long ago we got some info about Samsung Exynos 5 in a form of a slide, detailing GPU performance of 2.1 GPixels/s. This time the details listed are from an official document.

Confirming previous details, the SoC will feature 12.8GB/s of bandwidth through two 32-bit 800MHz memory ports, capable of supporting LPDDR3 and standard DDR3. On-chip support for USB 3.0 and SATA 3.0 has also been introduced. Another point of note is the inclusion of HSIC and C2C interfaces, capable of communicating with LTE modems.

Support for the MMC 4.5 standard is present, which offers embedded MMC speeds of 200MB/s, with the four channels also suggesting support for the SD UHS-II standard.

The 4-lane MIPI connection suggests support for incredibly high resolution image sensors, this is backed-up by details revealing that the chip's image processor is capable of handling a full 8-megapixels at 30fps.

As you may know, Exynos is a series of processors chips designed and manufactured by Samsung. Exynos CPU is included on all the latest Samsung GALAXY products. Users seems to be happy with the performance of this chips but CyanogenMod developers, NOT.

Responding to a query on xda-developers forum, CyanogenMod developer who goes by the forum ID "codeworkx" explained why he and other developers think that Exynos processors are bad for developers. It essentially boils down to lack of proper support from Samsung in terms of providing sources or documentation for their processors and when they do it's either outdated or incompatible.
