Details of first Broadwell "Y" mobile processors

The latest Intel Broadwell microarchitecture, fabricated on 14nm technology, will debut in the last quarter of this year, when the company will officially release first "Y" series processors for highly mobile devices. Preliminary model numbers of these SKUs are 5Y10, 5Y10a and 5Y70, and they will be followed by at least two new SKUs in Q1 2015. The distinctive feature of first Broadwell "Y" microprocessors is an ultra low 4.5 TDP. To meet the TDP requirement, the new CPUs will run at very low CPU and GPU frequencies, but they will also have decent Turbo and dynamic Boost frequencies, which will allow them more than double CPU/GPU performance when needed. Based on Intel's announcement from the beginning of June, the processors will be branded as Core M. Apparently, the 5Y70 may be re-branded as model "70", and model numbers of other SKUs could be changed as well.

Broadwell "Y" parts have 2 CPU cores and 4 MB of L3 cache. The 5Y10 and 5Y10a models run at 800 MHz, and have an integrated GPU clocked at 100 MHz. The microprocessors support Turbo Boost technology, that can increase operating frequency up to 2 GHz for one or both cores. The maximum boost frequency of the on-chip GPU is 800 MHz. Besides Turbo Boost, the CPUs support all basic Broadwell technologies, along with some advanced features such as VT-d virtualization. The 5Y10 and 5Y10A work with DDR3L and LPDDR3 memory with data rates up to 1600 MHz. The microprocessors are rated at 4.5 Watt. The 5Y10 supports a configurable TDP feature, which allows it to run at lower 4 Watt TDP.

The 5Y70 also has 2 CPU cores, but the enabled Hyper-Threading technology allows the processor to run 4 threads at once. The 5Y70 adds support for Trusted Execution and Vpro features. The base and turbo clock speeds of this part were increased to 1.1 GHz and 2.6 GHz respectively. The maximum GPU frequency was raised to 850 MHz. The 5Y70 supports DDR3L/LPDDR3-1600 memory, and has 4.5 Watt TDP:

The 5Y10, 5Y10a and 5Y70 SKUs have the PCH logic integrated, and they are produced in a BGA package.

Intel is really desperate to fight back iPad
for them to push Broadwell to 4.5W
and leave the laptop side not updated
until 2015.

The whole Skylake/Broadwell overlap for Desktop is even
more bizarre.
