A slide deck with lots of details about the Intel Coffee Lake-S platform hit the web. VideoCardz reposted the slides and writes the information confirms the 8th Gen Intel Core "Coffee Lake" processors will stick with LGA1151. One of the biggest novelties about Coffee Lake is that Intel is finally adding six-core models to its regular desktop lineup.
However, the continued use of LGA1151 doesn't mean you won't need a new motherboard for Coffee Lake. Intel hasn't officially confirmed this yet but ASRock stated users will not be able to use current motherboards for Coffee Lake. This implies customers will need to upgrade to a 300-series motherboard to install Coffee Lake.
The leak indicates enthusiast-class Coffee Lake processors will have a 95W TDP while mainstream models will stick to 65W. Coffee Lake has the same 24 PCIe lanes support as Kaby Lake and is expected to arrive in Q3 2017. Some of the information in the slides may be outdated, but it reveals the Z370 chipset launches in Q3 2017 and that the rest of the 300-series lineup will follow in Q1 2018.
The first slide provides a general overview of the Coffee Lake-S desktop platform's feature set:
Next is a look at how Intel positions its various desktop platforms until the second half of 2018. We can see that Coffee Lake launches in Q3 2017 in quad-core and six-core versions. Lower-end versions with just two cores are expected to follow in early 2018. The slide also reveals the 10W TDP Atom-based Gemini Lake is coming in Q4 2017 in dual-core and quad-core versions.
What changes with Coffee Lake?
As mentioned above, Coffee Lake will bring six-core chips to Intel's consumer segment. The Z370 will have new overclocking features, the processors will natively support DDR4-2666 and they will be able to accommodate next-gen Intel Optane memory. The slide also reveals the other 300-series chipsets, which arrive later, will have additional new features like Integrated Programmable Quad-Core Audio DSP, SoundWire Digital Audio Interface, USB 3.1 Gen 2 with 10Gbps support, integrated Intel WiFi/Bluetooth, integrated SDXC 3.0 controller, Thunderbolt 3.0 (Titan Ridge) with DisplayPort 1.4 and C10 plus S0ix support for Modern Standby.
A Core i3 with four cores and eight threads?
On a related note, there was also a rumor about an Intel Core i3-8300 processor with four cores and eight threads. While this would be great for consumers, the original source and the leak itself seem rather dubious so I would take this with a grain of salt.
