For years, Intel dominated the high-end CPU market. As a result, enthusiasts had to pay a premium for its best processors. But AMD's four-, six-, and eight-core Ryzen models forced Intel to reconsider its value story and Intel tries to do this with its new six-core Coffee Lake-based Intel Core i5-8600K.
Coffee Lake is Intel's codename for the third 14 nm process refinement following Broadwell, Skylake, and Kaby Lake. The integrated graphics on Coffee Lake chips allow support for DP 1.2 to HDMI 2.0 and HDCP 2.2 connectivity. Coffee Lake natively supports DDR4-2666 MHz memory in dual channel mode.
It features increased transistor gate pitch for a lower current density and higher leakage transistors which allows higher peak power and higher frequency at the expense of die area and idle power.
- It has additional two cores which effectively give it 50% more multi-threaded grunt than both the new Core i3 and its predecessor, the Core i5-7600K.
- The new Core i5 has 9MB L3 cache compared to 6MB for the Core i5-7600K too, so it’s a beast by comparison. The only place the old CPU trumps it is with the base frequency, which is 200MHz slower. However, the maximum turbo frequency of the new CPU is 100MHz higher than its predecessor at 4.3GHz.

Overclocking is configuration of computer hardware components to operate faster than certified by the original manufacturer, with "faster" specified as clock frequency in megahertz (MHz) or gigahertz (GHz).
Unlocked multiplier means you can change both multiplier and CPU frequency in your CPU settings to help overclock the system to higher speeds.
9mb smart cache:
Smart Cache is a level 2 or level 3 caching method for multiple execution cores, developed by Intel. Smart Cache shares the actual cache memory between the cores of a multi-core processor.
- More powerful than either of its Core i5 or Core i7 predecessors
- Six overclockable cores
- Unlocked multiplier
- More expensive that AMD’s six-core CPUs.
- Lacks Hyper-threading.
- Requires Heat-sink.
