Intel Skylake-U Series Lineup and Details:

Now we did detail the Skylake-U series lineup a few days ago but surprisingly, we have found two more chips that will be included in this lineup. The first chip whose name is “TBD”, comes in a dual core, multi threaded package that features clock speeds of 2.4 GHz (base), 3.4 GHz (boost) and has 4 MB of L3 cache. The second model with similar specs has different clock speeds of 2.0 GHz base and 3.1 GHz boost. Both of these models have two things in common, they feature the GT3e class iGPU and 15W TDP.

Starting with the lineup, first of all we have two Core i7 chips which include the flagship Core i7-6600U and the Core i7-6500U. You will see that Intel has once again simplified their naming scheme for mobility processors which was a serious mess with Broadwell generation of processors with weird naming schemes from the desk top range to the entire mobility series. The Core i7-6600U is a dual core with hyper threading enabled, it comes with a clock speed of 2.60 GHz and has a turbo boost of 3.40 GHz (3.20 GHz across all cores). The chip features the Intel HD Graphics 520 chip with 300 MHz base and 1050 MHz boost clock while supporting both DDR4-1866 MHz and DDR3L-1600 MHz memory. This model comes in the BGA package with a TDP of 15W that can be OEM configured down to 7.5W. The Core i7-6500U has the same specifications but comes with slower clock speeds of 2.50 GHz base and 3.10 GHz boost (3.00 across all cores). Both models feature 4 MB of L3 cache.

There’s also the Iris Graphics 540 chips that are codenamed, Core i7-6650U, Core i5-6560U and the Core i3-6360U. All of these chips are dual core models with hyper threading enabled, the clock speeds are 2.60, 2.20, 2.00 GHz base and 3.40, 3.20 and 3.10 GHz turbo boost for these chips, respectively. The Core i7 and Core i5 models come with 4 MB of L3 cache while the Core i3 model ships with 3 MB L3 cache. All of these chips have a TDP of 15W (9.5W Configurable TDP) and the graphics clock is maintained at 300 MHz base and 1050 MHz boost.

Moving down, we have two Core i5 and a single Core i3 model which include the Core i5-6300U, Core i5-6200U and Core i3-6100U. All the models have same specifications set of dual cores with hyper threading, Intel HD Graphics 520 (300 MHz base and 1000 MHz boost), 3 MB of L3 cache, 15W TDP and 7.5W configurable TDP. The only difference is in clock speeds where the Core i5-6300U is clocked at 2.40 GHz base and 3.00 GHz boost (2.90 across all cores), Core i5-6200 runs at 2.30 GHz base and 2.80 GHz boost (2.70 GHz across all cores) while the Core i3-6100U is clocked at 2.30 GHz clock speed and doesn’t feature boost frequency.

The Pentium and Celeron lineup forms the only three base line models of the lineup with the Pentium 4405U coming with a dual core (multi-threaded) design, clocked at 2.1 GHz (no boost clock). The chip features the HD graphics 510 chip with clock speeds of 300 MHz base and 950 MHz boost clock and support for DDR4, DDR3L and LPDDR3 memory. The chip comes with 2 MB of L3 cache and has a TDP of 15W that is configurable down to 10W. The Celeron 3955U and Celeron 3855U have dual core designs without hyperthreading, HD graphics 510 iGPUs clocked at 300 MHz base, 900 MHz boost, 2 MB of L3 cache and 15W TDPs. The 3955U is clocked at 2.0 GHz while the 3855U is clocked at 1.6 GHz.
