The Intel's specially binned i9-9900K, featuring 5GHz all core boost and base clock of 4GHz. This CPU is one of the most powerful Intel CPU in term of day-to-day and gaming performance but with TDP of 127W, bulky air cooler or 240mm AIO is recommended to make sure the CPU doesn't overheat, and open loop liquid cooling if you want to OC. [Jun '20 ColdSpy]

MORE DETAILS

The Intel 5960X sports eight cores and sixteen threads. That's two more cores than we have ever seen on a consumer processor before and as such this $1,000 processor offers record breaking multi-threaded CPU horsepower. Unfortunately the 5960X is clocked at just 3 GHz base and 3.5 GHz turbo which, for single and dual-core workloads, renders it around 15% slower than a $69 G3258 on stock clocks! The 5960X is only compatible with Intel's new X99 chipset which requires new DDR4 RAM and is currently far more expensive, with little consumer benefit, than DDR3. All in all the i7-5960X processor is largely irrelevant for consumers as it's far far too expensive. [Sep '14 CPUPro]
