Intel's Skylake Processor Lineup for Retina MacBook Revealed

Following a closer look at Intel's upcoming Skylake processor lineup (http://www.macrumors.com/2015/07/24/intel-skylake-processors-leaked-slides/) for the MacBook Air (http://www.macrumors.com/2015/08/11/skylake-processors-for-macbook-air/), CPU World (http://www.cpu-world.com//news_2015/2015082701_Details_of_6th_generation_Core_M_processors.html) has shared new details about sixth-generation Core M chips appropriate for the 12-inch Retina MacBook. Intel reportedly may brand the low-power Skylake-Y chips as Core m3, Core m5 and Core m7 based on performance.

 The low-end Core m3 6Y30 has a 900 MHz dual-core processor with Turbo Boost up to 2.2 GHz. The chip has 4MB of L3 cache, HD 515 graphics, a maximum GPU frequency of 850 MHz and 4.5 watt thermal design power (TDP). This chip would likely be suited for the base model 12-inch MacBook sold for $1,299.
 
 The mid-tier Core m5 6Y54 and Core m5 6Y57 are similar chips with 1.1 GHz dual-core processors and Turbo Boost up to 2.7 GHz and 2.8 GHz respectively, 4MB of L3 cache, HD 515 graphics, a maximum GPU frequency of 900 MHz and 4.5 watt TDP. These chips would likely be suited for the high-end stock model 12-inch MacBook sold for $1,599.
 
 The high-end Core m5 6Y75 is a 1.2 GHz dual-core processor with Turbo Boost up to 3.1 GHz, 4MB of L3 cache, HD 515 graphics, a maximum GPU frequency of 1 GHz and 4.5 watt TDP. This chip would be suited for the top of the line 12-inch MacBook model that carries a $150 premium over systems with the high-end stock chip.

 CPU World shared further details about the processor specifications, noting that Core M chips can be run at 7 watts to allow for higher CPU clock speeds. Apple boosted the 900 MHz 5Y31 chip (http://ark.intel.com/compare/84672,84669,84666) to 1.1 GHz, 1.1 GHz 5Y51 chip (http://ark.intel.com/compare/84672,84669,84666) to 1.2 GHz and 1.2 GHz 5Y71 chip (http://ark.intel.com/compare/84672,84669,84666) to 1.3 GHz for the current 12-inch MacBook lineup.

All chips have up to 2 SATA 6Gb/s ports, 10 lanes of PCI-Express interface, 6 USB2/USB3 ports and eMMC 5.0 interface. They support USB OTG and Rapid Storage Technology 14. The Core m microprocessors work with DDR3L-1600 and LPDDR3-1866 memory, and they are rated at 4.5 watt TDP and 3 watt SDP. They can also run at higher 7 watt TDP if needed.

Last month, a leaked Intel slide deck (http://www.macrumors.com/2015/07/24/intel-skylake-processors-leaked-slides/) revealed that "Y" series Skylake processors appropriate for the 12-inch Retina MacBook will have up to 17% faster CPU performance, up to 41% faster Intel HD graphics and up to 1.4 hours longer battery life compared to current-generation Core M architecture.
 
 Intel's sixth-generation Core M processors are expected to launch next month, possibly at the IFA Berlin trade show this September 4-9.
