Broadwell Y processor line has three SKUs

Written by Fuad Abazovic



5Y70, 5Y10a and 5Y10

Broadwell, Intel's 5th generation Core, is coming in three SKUs and the fastest of them all is the Core 5Y70

This might not be the final name, but this 4.5W TDP part has two cores and four threads, 1.1 GHz base clock and 2.6GHz maximum Turbo clock. The graphics core works at 100MHz in idle and 850MHz under full load. It supports LPDDR3 or DDR3L memory with 1600MHz speed and has 4MB cache.


Core 5Y10a is the runner up

The runner up is currently codenamed Core 5Y10a and it comes with two cores and two threads. It works at 800MHz by default, but with the help of Turbo it can reach 2.0GHz for in single and dual-core mode.

The graphics part works at 100MHz with 800MHz as the max graphics clock. It is also a 4.5W part and it supports the same 1600MHz LPDDR3 or DDR3L memory. One major difference between the Core 5Y70 and Core 5Y10a is the lack of Intel Vpro and Intel TXT at the slower model.

vPro plays a significant role in the business environment as it is umbrella marketing for a few technologies including Hyperthreading, Turbo Boost 2.0, VT-x, Trusted Execution Technology, and Intel Active Management Technology (AMT).

All these technologies, especially the last two, have a major role in business and enterprise environments and therefore you can imagine that a lot of business users will insist on getting 5Y70-based machines. The faster CPU also means it will come at a higher price, but the common practice was that business users had to pay a bit more than others.


Core 5Y10 at 4W TDP


The last processor on the list is the Core 5Y10 and this one shares almost all the specification with the Core 5Y10a. It works at 800MHz by default, but it can reach 2.0GHz on Turbo.

The graphics part works at 100MHz to 800MHz. The Core 5Y10 supports the same 1600MHz LPDDR3 or DDR3L memory but it comes with the TDP limited to 4W as an option. We don't know how Intel means to keep its TDPs at the same clock and there is an indication that the final turbo core clock for the Core 5Y10 might end up slightly lower in order to get the 4W TDP.

Machines based on Core 5Y00 Broadwell 4W to 4.5W TDP cores will come in Q4 2014 and they will replace the Core i7 4610Y that comes with 11.5W TDP at the top of the Y-processor line. Getting down from 11.5W TDP to 4.5W in a single generation is a huge achievement and will help Intel to establish a great line of thin detachable notebooks with passive cooling.
