Advanced Micro Devices is shipping a 16-core Ryzen Threadripper central processing unit (CPU) that the company says takes the speed crown away from Intel for the first time in a decade.

AMD said the world’s fastest CPU is the AMD Ryzen Threadripper 1950X, which runs at a base speed of 3.4 GHz and a boost speed of 4 GHz. It comes in with a Cinebench benchmark score that ranges from 2,900 to 3,100, depending on the system and its overclocking, or how much it is revved beyond the usual spec. Those are varied scores, but they show that AMD is competitive with Intel for the speed crown for the first time since 2006. (Another 100 reviews are expected to hit today from overclockers, and AMD expects even better results).
