Intel Desktop Roadmap Confirms Broadwell & Skylake desktop SKUs

by Hilbert Hagedoorn on: 05/05/2015 07:51 AM | source: | 19 comment(s)

Over at the Chinese based pconline two slides have appeared showing and confirming the 2015 and 2016 line-up for desktop processors from Intel. It also confirms Broadwell-E in 2016.

The two leaked slides show quite a bit really, both 5th gen Broadwell processors and 6th Generation Skylake series processors. As expected soon we will see 14nm Broadwell Core i5-5675C, and the Core i7-5775C processors. Just to recap, versions with the 'C" extension are the desktop LGA 1150 models, the 'R" models get a BGA socket.

The C models will come with an unlocked multiplier (in the past that was K or X model). Initially five models will be launched but three of them are BGA and thus soldered onto the PCB socket.

All Broadwell based ICs will get four cores, IGP wise the Iris Pro 6200 and JEDEC DDR3 1600 MHz support. And again all models will get a 65W TDP, which is lower compared to Haswell with its 84W/95W TDP.

Broadwell
CPU	Core i7-5775C	Core i5-5675C	Core i7-5775R	Core i5-5675R	Core i5-5575R
Codename	Broadwell	Broadwell	Broadwell	Broadwell	Broadwell
Package	LGA1150	LGA1150	BGA1364	BGA1364	BGA1364
Cores/threads	4/8	4/4	4/8	4/4	4/4
Frequency（GHz）	3.3-3.7	3.1-3.6	3.3-3.8	3.1-3.6	2.8-3.3
memory	DDR3-1600	DDR3-1600	DDR3-1600	DDR3-1600	DDR3-1600
IGP	Iris Pro 6200	Iris Pro 6200	Iris Pro 6200	Iris Pro 6200	Iris Pro 6200
L3 Cache	6MB	4MB	6MB	4MB	4MB
Fab	14nm	14nm	14nm	14nm	14nm
Unlocked multiplier	Yes	Yes	No	No	No
TDP	65W	65W	65W	65W	65W

On the Skylake side the slides show the Core 6400/6500/6600/6700 series, tagged as i5 and i7 in the charts here is what we know thus far. The Core i7 6700K would be a 4.0 Ghz processor that can boost to 4.2 GHz, the 6600K model would do 3.5/3.9 GHz.

Core i7 6700K 4 cores and Hyper-Threading, 4.0GHz frequency, 4.20GHz maximum Turbo Boost frequency, 8MB last-level cache, dual-channel DDR3/DDR4 memory controller with 1600MHz or 2133MHz support, 95W TDP, Intel HD Graphics 5000-series integrated graphics core, LGA1151 packaging

Core i5 6600K 4 cores, 3.50GHz frequency, 3.90GHz maximum Turbo Boost frequency, 6MB last-level cache, dual-channel DDR3/DDR4 memory controller with 1600MHz or 2133MHz support, 95W TDP, Intel HD Graphics 5000-series integrated graphics core, LGA1151 packaging.

Model	Cores/Threads	Fab	Core Freq	Core Boost	Cache L3	Memory	TDP	Package	Unlocked
Core i7 6700K	4/4	14nm	4.0	4.2	8 MB	DDR4 2133 DDR3L 1600	95W	LGA 1151	Yes
Core i5 6600K	4/4	14nm	3.5	3.9	6 MB	DDR4 2133 DDR3L 1600	95W	LGA 1151	Yes
Core i7 6700	4/8	14nm	3.4	4.0	8 MB	DDR4 2133 DDR3L 1600	65W	LGA 1151	No
Core i5 6600	4/4	14nm	3.3	3.9	6 MB	DDR4 2133 DDR3L 1600	65W	LGA 1151	No
Core i5 6500	4/4	14nm	3.2	3.6	6 MB	DDR4 2133 DDR3L 1600	65W	LGA 1151	No
Core i5 6400	4/4	14nm	2.7	3.3	6 MB	DDR4 2133 DDR3L 1600	65W	LGA 1151	No
Core i7 6700T	4/8	14nm	2.8	3.6	8 MB	DDR4 2133 DDR3L 1600	35W	LGA 1151	No
Core i5 6600T	4/4	14nm	2.7	3.5	6 MB	DDR4 2133 DDR3L 1600	35W	LGA 1151	No
Core i5 6500T	4/4	14nm	2.5	3.1	6 MB	DDR4 2133 DDR3L 1600	35W	LGA 1151	No
Core i5 6400T	4/4	14nm	2.2	2.8	6 MB	DDR4 2133 DDR3L 1600	35W	LGA 1151	No

Skylake is the codename used by Intel for the 14nm processor microarchitecture under development and due to launch in 2015 as the successor to the Broadwell architecture. Intel 14nm Skylake processors will feature PCIe gen 4, DDR4 Memory and SATA Express support.

While desktop Broadwell will probably be a good chip it seem to be quickly swamped by Skylake.
Difficult to see a reason to go with Broadwell even if it's big improvement.

To use the same board. Broadwell will use LGA 1150, Skylake moves on to 1151.

Well this is good news for anyone on 1150 socket u can upgrade to 14nm without having to buy a whole new system.

3.1Ghz for i5 5675C and 3.3Ghz for i7-5775C? You got to be kidding me. Skylake cant come fast enough.

Notice how the Skylake lists show memory as DDR3-1600, but the Broadwell lists, on Socket 1151, show the memory as DDR4 2133 or/DDR3L 1600.

Are you sure? :3eyes:

Did you maybe mix it up a little by accident, since Broadwell (1150) does indeed list as DDR3, and Skylake as LGA1151 does support both DDR4 and DDR3.

Might be tempted to go for a top end Broadwell chip since it'll fit in my board. Hopefully they'll overclock like mad being 14nm.

Am not really getting the high TDP of all the chips? Will wait for "Skylake-E" anyway, but still I was hoping for a much improved TDP..

Just because it will fit the socket, doesn't mean the board will actually support it.

Unless Intel starts using mobile designs, you're really not going to see much lower TDP for a desktop chip.

Btw: Unless you're designing cooling solutions or pre-built systems, the TDP is completely meaningless.

I will keep my 2600k , I really really really want to change it , except I would like to see visible performance gain. to change only for nice motherboard is a reason but not too strong

Price may be lower this time round and/or they are going after AMD's APU/GPU performance or a combination of both... Can't see why else would Intel have these chips out.

Same.

Might actually pick up a 6 core this summer. At least I'd be somewhat safe if Windows 10 and DX12 would suddenly make extra cores more useful.
