The i9 designation is reserved for Intel's fastest processors that can go in a desktop you or your friend (and not a multimillion dollar business) might own. These things are very fast - with up to 18 cores in each processor, capable of running 32 threads simultaneously. The i9 processors, which were first introduced back in the late winter of 2017, are also super expensive, but Intel is hoping you love the luxury and power of the i9 brand enough to buy a hobbled version for your laptop, because the i9-8950HK is now available in a wide range of mobile workstations and gaming laptops.
