Core i7-8700 3.2GHz (Coffee Lake) Socket LGA1151 Processor - Retail

Coffee Lake

Intel-Logo These codenames belong to the eight generation of Core CPUs which follow on from Kaby Lake and Skylake, although while they still share the 1151 pin socket design, due to the variety of optimisations to Coffee Lake CPUs they will not be compatible with older chipsets. Instead these processors will require Socket 1151 motherboards bearing the 300-series nomenclature. The Intel Core i7 processors from the Coffee Lake generation offer six CPU cores, high clock frequencies and new Turbo Boost features - all with a mere 65 Watt TDP!

Intel's 8th-gen i7 CPUs

The Intel Core i7-8700 at a Glance:

  • 6 physical cores, 12 logical cores thanks to SMT!
  • 3,2 GHz Base Clock with 65 Watt TDP
  • 4,6 GHz Boost Clock with Turbo Boost 2.0
  • 12 Megabyte L3 Cache
  • Support for DDR4-2.666 (Dual Channel)
  • Revised UHD Graphics 630
  • Only compatible with Intel 300-series chipsets
  • Attention: Boxed version with CPU cooler!

The Intel Core i7-8700: Hexa-Core Processor with Hyper-Threading

The Intel Core i7-8700 comes with a clock frequency of 3,2 GHz which, using Turbo Boost 2.0, can increase up to 4,6 GHz when needed. However, it should be noted that the boost clock rates vary depending on 1-core, 2-core, 4-core or 6-core operation, which means that the optimum performance can always be obtained from the Coffee Lake CPU, allowing the user to determine what performance is available for games or applications. The L3 cache has increased to 12 Megabytes, the Thermal Design Power (TDP) sits at 65 Watts and as a Core i7 this Hexa-Core processor comes with Intel's Hyper-Threading technology and can therefore not only process six but rather 12 threads simultaneously.

A fundamental difference compared to Skylake- and Kaby Lake generations lies in the fact that Coffee Lake only uses the fast and efficient DDR4 RAM. The quad-core processors support a maximum standard clock frequency of 2.400 MHz, while the hexa-core processors permit clock frequencies up to 2.666 MHz. The LGA 1151 socket from Intel is retained, but it is essential to ensure that a motherboard with 300 series chipset is used, otherwise the processor could be damaged due to the differences in the power supplied to the chip.

In direct comparison with the 200 series, the 300 series offers an optimized power supply for the entire CPU, which results in improved potential for overclocking. The integrated graphics unit has also been optimized with regard to clock rates and drivers and has now been christened as the Intel HD Graphics UHD 630. With its 24 Execution Units, it offers more than enough graphics power for Intel Quick Sync, GPU computing and of course some games in between. Furthermore, the DirectX 12 graphics unit with the feature level 12_1, OpenGL 4.5 and OpenCL 2.0 compatibility also supports 4K playback, UHD resolutions at 60 Hz via DisplayPort - provided a compatible motherboard is used.

This boxed version of the processor comes with a compatible CPU cooler from Intel.

Cracking processor

Having swapped this in to replace a Ryzen 7 1700X which I had since launch, (yes I know why would you ?) Well for me just for a change and to see what the other side has brought to bare. Performance is around the same at the Ryzen when that is OC'd to 3.8Ghz, in that light I am saving on heat out put and energy consumption. The I7 8700 is better in games due to the IPC and that is my main use, but nice to have the 12 threads for VR or if I do some content work. I toy'd with getting the i5 8400 but glad I plumbed for the I7.
