Details about Intel's upcoming Broadwell-U processors were leaked by the Chinese version of VR Zone. Expected to be introduced at CES in January 2015, the Broadwell-U series will span from the low-budget Celeron to the flagship Core i7 series. If the details are accurate, Intel's highest-end Broadwell-U parts will get the new Iris Graphics 6100 graphics while lower-end models will stick with slower versions.
The IGP will reportedly scale up to 1100MHz, while the CPU will hit speeds as high as 3.4GHz with Turbo. One of the charts is mislabeled, but it looks like the processor will support memory speeds up to 1866MHz with DDR3 RAM and 1600MHz with low-power DDR3L memory.
The standard Broadwell-U variants are listed with HD Graphics 6000 and 5500. Those onboard GPUs will only range up to 1000MHz, according to the spec tables, and they'll likely differ from Iris implementations in other ways. The standard CPUs otherwise appear similar to their Iris-equipped siblings, but the clock speeds are slightly lower, with Turbo frequencies topping out at 3.2GHz.
A handful of Pentium and Celeron processors appear at the bottom of the lineup. If the leaked details are accurate, these models should have even lower clock speeds and downgraded Intel HD Graphics. They're listed with the same 15W TDP as all the other Broadwell-U offerings, though.
