Intel has officially moved the embargo forward for their 8th generation desktop processors known as Coffee Lake. The embargo allows us to cover details that were presented by Intel during a event few days ago and include specifications, prices and performance numbers (official) on the 8th gen processors.

Intel 8th Generation Desktop Core Family Officially Announced - First Core i7 With 6 Cores, First Core i3 With 4 Cores and a Core i5, 6 Core CPU Under $200 US

Intel is detailing a lot in their presentation regarding the 8th generation desktop family but they are also keeping a few details out of our reach. The 8th generation desktop family comes will be arriving at a time when Intel faces a heated battle with its competitor in the CPU department that has long been vacant of any competition. There are a few things happening with Intel's desktop platform and the processor family which can be seen as a direct or indirect result of this uprising. So let's get on with the details.

Intel Coffee Lake Is Built on the Same Architecture as Kaby Lake, Improved 14nm++ Process and More Cores

First of all, what is Coffee Lake? In simple terms, Coffee Lake is an improved Kaby Lake that is been possible with the latest 14nm++ process node. Intel briefed in their webinar that the Coffee Lake is on the same architectural level as Kaby Lake with no changes at all. Aside from that, the new 14nm process allows for improved power efficiency and higher clock speeds. There's a reason that Intel is bumping up the core count across their entire range of processors. The Intel Core i7 and Core i5 lineup gets 6 cores (HT/Non-HT) while the Core i3 lineup gets 4 cores.

The Intel Core i7 and Core i5 processors with 6 cores feature the same TDPs as their predecessors so bumping up the core count hasn't changed the TDP numbers. Actual power consumption may vary during testing real world applications but for that, you'd have to wait for our review in coming weeks. You will also note that Intel has given a fairly good bump to both CPU and integrated GPU clock speeds which is only possible with the new and improved 14nm++ process.

Intel Coffee Lake Is Only Supported by The 300-Series Chipset - LGA 1151 On Z370 Offers No Backward Compatibility - Full Platform Details

The next significant detail is the Intel 300-series platform. Intel is confirming that the Coffee Lake processors are only compatible with the 300-series chipset. The Z370 motherboards come with a socket known as LGA 1151 and that is the same socket we have seen on the consumer platform since Skylake. But with Coffee Lake, LGA 1151 on Z370 is no longer compatible with older CPUs. Even Coffee Lake processors are not backward compatible to 100 or 200 series motherboards.

The reason cited by Intel is the change in electrical lanes and power delivery that Z370 improves substantially. We did have a word with some motherboard manufacturers and while they reveal that Coffee Lake may work with older motherboards, it won't deliver the same level of stability or clocking as on the Z370 series motherboards.

So with one of the controversies explained, let's head over to the platform details. The 8th gen desktop platform has a range of new features that mainly include:

  • More Cores
  • More Intel Smart Cache
  • Best In Class Design
  • Enhanced Overclocking
  • Improved 14nm Process

And of course, powering the new platform is the Z370 PCH. The PCH offers the following:

  • Improved Power Delivery for 6 Core processors
  • Enhanced Package Power Delivery For overclocking
  • Memory routing support for DDR4-2666
  • Rec.2020 & HDR Support, HEVC 10-bit HW Decode/Encode, VP9 10-bit HW Decode
  • Integrated USB 3.1 Gen2 (10 Gbps)
  • Support for integrated Intel wireless AC (WiFi 802.11ac R2 & Bluetooth 5)
  • Intel Optane memory support

Intel Coffee Lake CPUs Have 16 PCIe 3.0 Lanes, PCH Supports 24 PCIe 3.0 Lanes - These Make Up The 40 PCIe Platform Lanes

Now one thing you might have noticed in other articles is that they state Intel Coffee Lake platform will feature 40 PCIe Lanes. That's true but not entirely an accurate representation. As you see, Intel does has 40 PCIe 3.0 lanes on their upcoming family but those are a combination of CPU and PCH lanes. All Coffee Lake CPUs feature 16 PCIe Gen 3.0 lanes while the Z370 PCH features 24 PCIe 3.0 lanes. These make up the 40 PCIe 3.0 lanes that Intel claims of.

This means that people can add in two GPUs for SLI or mGPU support which will be given to the CPU while PCH can allow for additional devices such as PCIe / M.2 storage or Intel Optane support.

The Intel 8th Gen, Core Desktop Family Full Specifications and Prices

At launch, Intel will introduce 6 new Coffee Lake CPUs to consumers. These include the flagship Core i7-8700K, Core i7-8700, Core i5-8600K, Core i5-8400, Core i3-8350K and Core i3-8100. Intel includes three "K" unlocked CPUs in the lineup while the rest are locked CPUs that don't feature overclocking but great for budget users in their own place. Following are the detailed specs for these CPUs:

Intel Core i7-8700K – The Coffee Lake Flagship With 6 Cores and 4.3 GHz Boost Across All Cores

The Intel Core i7-8700K will be the flagship processor of the lineup. It will feature 6 cores and 12 threads. The chip will be compatible with the LGA 1151 socket on the Z370 chipset only. The chip will be Intel’s first hexa core product and will be based on the 14nm process node.

The Intel Core i3 chips will not feature boost clocks but they will have a more stable base clock speed and pricing is set at $168 US for the unlocked model.

Intel Core i5-8400 - A 6 Core Chip Under $200 US, Is This The Dream Gaming Chip?

The one other chip that is worth mentioning is the Intel Core i5-8400. This is a 6 core processor with no hyper threading and no overclocking enabled so what makes it so special? The pricing. Intel Core i5-8400 has been priced at a remarkable $182 US range which is under the $200 US pricing range. This makes it a very competitive chip for the gaming desktop market as you can have a modern 6 core gaming processor for a fantastic price. We are very interested to test the chip out ourselves.

Intel Details Overclocking and Gaming Performance Figures - Our Advice, Wait For Reviews

Intel has also detailed some performance numbers for their Coffee Lake processors. First of all, we have overclocking details. Intel claims that Coffee Lake processors are the best chips designed for overclocking. There are a range of new features supported by the chips which include:

  • Per Core Overclocking
  • Max Memory Ratio Up To 8400 MT/s
  • Real-Time Memory Latency Control
  • Extended PLL Trim Controls
  • Enhanced Package Power Delivery

The combination of these tools and features will presumably deliver better overclocking and even faster performance out of the chips. In terms of pure gaming performance, Intel says that the Core i7-8700K, when paired with a GeForce GTX 1080 Ti class graphics card delivers up to 195 FPS in the Gears of War 4 title, that's a 25% increase in FPS over the Core i7-7700K. The extra number of core also deliver better streaming performance that is a must in today's gaming ecosystem. We can see up to 45% better performance in Player Unknown Battlegrounds while gaming, streaming and also recording at the same time versus a Core i7-7700K. Compared to a 3 year old PC with something like Haswell or Ivy Bridge inside it, we can see a difference of 2X which sounds great.
