Massive Intel 14nm Skylake Leak – Multiple eDRAM Configurations and Desktop Variant to have Configurable TDP

Massive Intel 14nm Skylake Leak – Multiple eDRAM Configurations and Desktop Variant to have Configurable TDP

We just received a major leak that updates the original Intel Skylake leak
published some time ago. We have now learned more details about the
Skylake’s different variants especially the desktop ‘S’ variant
including the TDP, eDRAM and Memory configurations. Needless to say this
is a very big leak and is going to be a detailed post, so buckle up.

Intel 14nm Skylake Details Leaked -Configurations, TDP, Memory and eDRAM Detailed

Alright, let me begin by saying that since this is an aggregate post
which has the latest leak included the sources are numerous. We have our
Own Sources, Sweclockers and CPU World.
You may recall that Skylake is coming in 4 flavors, namely the U/Y/H
and S variants. The ‘S’ variant is the variant intended for desktops
while the U, Y and H variants are all BGA packaged variants intended for
the mobile platform. We received a very extensive description that
updates our original leak. Before we had a hazy idea about the different
TDP ranges but now we can assign those TDP ranges to the specific eDRAM
and Graphics Configurations. Basically one of the biggest points of
Skylake is that it will feature support for  DDR4 Ram and will be based
on the 100 Chipset ‘Sunrise Point’ of the ‘Sunrise Bay’ platform.

  • Now Variant ‘U’ and ‘Y’ will integrate this PCH (Platform Control
    Hub) on the die while the ‘S’ and ‘H’ variants will not and require the
    chip separately.
  • The DMI 2.0 is getting replace with the DMI 3.0 Interface that promises speeds of upto 8 GT/s.
  • Variants ‘U’ and ‘Y’ will support 1 DIMM Slot per Channel while the ‘S’ and ‘H’ Variants will support 2 DIMMs per channel.
  • The IVR (Internal Voltage Regulator) is to be abandoned for Skylake Processors.

Now take a look at the table below, I have tried my best to sum it up
in a coherent fashion but I think it still needs an explanation
afterwords:

Intel 14nm Skylake Configuration Table
Variant SKL-Y (BGA) SKL-U (BGA) SKL-H (BGA) SKL-S (LGA)
Cores Configurations 2 2 / 2 4 / 4 4 / 2 / 4
Graphic Configurations GT2 GT2 / GT3e GT2 / GT4e GT2 / GT2 / GT4e
eDRAM 64MB – GT3e 128MB – GT4e 64MB – GT4e
Memory LPDDR3 1600Mhz LPDDR3 1600Mhz DDR4 2133Mhz DDR3L/DDR3L-RS 1600Mhz, DDR4 2133Mhz
TDP 4W 15-28W 35-45W 35-95W

So basically the table displays the different configurations of the
Intel Skylake Variants, complete with the eDRAM and TDP information. We
see that variants Y and U will only support DDR3 Memory while as H and S
will indeed support DDR4 Memory. Since the S Variant supports multiple
memory types, motherboard manufacturers will have to work a little
harder and come up with different models with different memory types.
Anyways the summary of the configurations are as follows:

  • SKL-Y Config 1: 2 Cores with GT2 Graphics and
    LPDDR3 1600Mhz Memory Support. TDP is 4W andeDRAM statistics are
    unknown, most likely because it will not have eDRAM.
  • SKL-U Config 1: 2 Cores with GT2 Graphics and LPDDR3 1600Mhz Memory Support with 15W TDP.
  • SKL-U Config 2: 2 Cores with GT3e Graphics and 64MB of eDRAM, supports LPDDR3 1600Mhz Memory and 28W TDP.
  • SKL-H Config 1: 4 Cores with GT2 Graphics and DDR4 2133Mhz Memory Support. TDP is 35W.
  • SKL-H Config 2: 4 Cores with GT4e Graphics and DDR4 2133Mhz Memory Support. Features 128MB eDRAM and a TDP of 45W.
  • SKL-S Processors will support dual memory type namely the DDR3L/DDR3L-RS
    1600Mhz and DDR4 2133Mhz. They will also support configurable TDP and
    come in two models, namely the 35W and 65W designs with the exception of the quad core (GT2 Only) which will come in a 95W TDP Design.
  • SKL-S Config 1: 2 Cores with GT2 Graphics and Dual Memory and Dual TDP.
  • SKL-S Config 2: 4 Cores with GT2 Graphics with Dual Memory and 95W TDP.
  • SKL-S Config 3: 4 Cores with GT4e Graphics with Dual Memory and 64MB of eDRAM. These will feature Dual TDP.

On a concluding note I would like to add that many of these models
support configurable TDPs so the SKUs might see more adjustments before
they roll out, although the chances of that happening are quite low at
this point. That’s all folks.
