Intel has indicated that its 14nm process node is finally maturing after several delays, announcing four new models of Core M mobile-centric processors based on its fifth-generation Broadwell microarchitecture.
Intel has had a rocky road leading to Broadwell. Poor yield of test batch production pushed the launch back by a quarter
, with the company admitting that 14nm was a harder shrink than expected
. In February this year Broadwell hit another delay, this time blamed on excess stock of Haswell chips
, with Intel finally releasing the first Broadwell processors in the form of the mobile-centric Core M family in September this year
Now, Intel appears to be finally getting to grips with the challenges of 14nm and has announced four more Core M processors featuring improved specifications over those originally released. The Core M-5Y10c sits above the M-5Y10 with a boosted 300MHz minimum graphics clock but otherwise identical 2GHz two-core four-thread setup. The Core M-5Y31 sits above both with a 900MHz core processor clock boosting to 2.4GHz and an 850MHz peak GPU frequency. The Core M-5Y51 is more impressive yet, boasting a 1.1GHz core and 2.6GHz turbo CPU frequency and 900MHz graphics, while the range tops out at the Core M-5Y71 - an upgrade from the 1.1GHz Core M-5Y70 - with a 1.2GHz base and 2.9GHz turbo CPU clock. All models maintain the same 4.5W thermal design profile as their predecessors.
With the 14nm yield issues finally ironed out, everything seems on-track for Intel to launch its desktop-variant Broadwell processors next year - at which point the microarchitecture will be ready for comparison to equivalent Haswell processors.
