The Core i9 will include an unprecedented 18-core model, in addition to 10-, 12-, 14- and 16-core versions.
These new chips include Intel's updated Turbo Boost 3.0, which allows the CPUs to temporarily increase their power for short bursts without overheating.
Desktops and DIY kits with Intel's new X299 motherboard chipset will be available right away, so there's no delay on building your own Core i9 rig.
Intel designed a new liquid cooling system, called TS13X to keep these 140-watt TDP chips under control (but you'll have to buy it separately for about $100).
Intel says these will be up to 15-percent faster than the former enthusiast CPU family, Broadwell-E.
Here's why you're probably not going to get one of these new Core i9 CPUs.
They're insanely expensive. Intel estimates $1,999 for the 18-core Core i9-7980XE, on top of the cost of the rest of your PC. Other Core i9 CPUs will cost $999-$1,699.
These chips are desktop-only, at least for now.
Newer, faster Intel chips are on the horizon, as Intel is already teasing the not-yet-official eighth-gen "Coffee Lake" Core i-series CPUs, which it hints will be 30 percent faster than the current seventh-gen chips.
Pricing and release date
Note that Intel hasn’t released the clock speeds of all of the Core i9 family yet. They’re all unlocked, though—ready and waiting to be overclocked. Here’s a summary
