In November Mobile Geeks hardware news site published leaked Intel slides, detailing future Atom "ValleyView-T" System-on-a-chip (SoC) for tablets. Perhaps, the most interesting tidbit in those slides was the fact that ValleyView-T processors will launch in 2014, rather than at the end of 2013. As it turns out, not only tablet chips, but also desktop and mobile Atom products from Bay Trail platform were pushed back to the first half of 2014. Based on slides, posted in 3DCenter forum, qualification samples of ValleyView-M and D (mobile and desktop) parts will be available in October - December 2013 timeframe, and the production will start in November 2013. Expected launch time of desktop and mobile Atom ValleyView microprocessors is February - April 2014.
Besides the roadmap, the posted slides also provide detailed side-by-side comparison of Bay Trail tablet, mobile and desktop variants. Common features for all parts will be 22nm manufacturing process, up to 4 CPU cores with out-of-order instruction execution, and 7th generation graphics with Burst technology, offering up to 3x performance of CedarView GPU. The graphics unit will support DirectX 11. Integrated video encoder will be capable to perform full hardware acceleration of H.264, MPEG2 and MVC formats, and decode MPEG2, MVC, H.264, WMV9 and several other formats at 1080p resolution. The on-chip display controller will have 2500x1600 maximum resolution, when using eDP, or DP 1.2 on mobile and desktop chips. The controller will also support HDMI rev1.4. A security engine on ValleyView SoCs will feature secure boot, malware protection, Random Number Generator, AES instructions, and a number of other security-related technologies.
ValleyView-D and -M SoCs will be able to reach 2.7 GHz with the help of Burst technology. The chips will support up to 8 GB of DDR3L memory, operating up to 1066 MHz on mobile, and up to 1333 MHz data rate on desktop parts. Mobile Atoms will have a handful of low-power states down to C7, and their TDP is expected to be in the 4 Watt - 6.5 Watt range. The desktop SoCs will have only one low-power state, and have less than 12 Watt TDP.
ValleyView-T Atom CPUs will be produced in smaller 17x17mm BGA form factor than -M and -T counterparts, and consume less than 3 Watt. The chips will have C7 low power state, and work with LPDDR3 memory. The maximum amount of supported memory on tablet-oriented processors will be limited to 4 GB. ValleyView-T will be shipped only with 32-bit Window 8 CS operating system.
