Broadwell as we know is the code name for the generation of processors that will replace the current Haswell and that was due to arrive on the market by the beginning of next year but that has encountered some technical problems and was delayed by a few months . Currently it is too early to learn about specific models and operating frequencies but some new details have emerged about the lineup and the internal organization of the various families.
In the mobile sector there will be in fact the lines H, U and Y . The first will be the one to performance , that is addressed to the notebook, workstation or gamestation . H processors will be available in two versions, a single-chip , ie CPU, GPU, and northbridge controller all integrated on a single die or two chips , with the northbridge outside. In the first case you will have up to two cores while the second of course you will reach quad-core configurations, as is currently the practice with Haswell. These new Broadwell also integrate graphics subsystems of type GT2 or GT3 , will have up to 6 MB of L2 cache memory and support DDR3L-1600 . The TDP will be 47 W but some will have a TDP configurable, as is already the case for existing Haswell and can thus operate with a TDP of 37 W.
Processors Intel Core belonging to the lines U and Y instead will obviously single-chip dual core, and then only, with a maximum of 4 MB of L2 cache . U models support up to 16 GB of RAM DDR3L-1600 or up to 8 variant LPDDR3-1600 and will have TDP of 28 or 15 W. The first will be matched to the type of PGI GT3 while the latter may be utilizzarne type GT2 GT3 . The most interesting, however, will be the Y-type ultra low power which will have a maximum TDP of just 4.5 W (3.5 for models with configurable TDP). These processors will have 4 MB of L2 cache, GPU GT2 and will support up to 8 GB of RAM LPDDR3-1600.
