At its annual AMD's 16-core Threadripper 1950X.
No further details or specifications of the new enthusiast processors were announced, but AMD did state that both processors would use the same socket and work with the same motherboards as current-generation Threadrippers. AMD also showed a demonstration of the 24-core model handily defeating Intel's current flagship Core i9 in a Blender 3D rendering benchmark. The two processors, and potentially others in the series, will be launched beginning in Q3 2018.
AMD also showed off a Nano version of its Microsoft Xbox One S and Xbox One X.
There was no news of next-generation Radeon GPUs for gaming, but the company did show off a new Radeon Instinct compute accelerator for servers and workstations, fabricated using a brand new 7nm manufacturing process. It will launch in the second half of 2018, and consumer GPUs might benefit from the architecture and process technology in 2019. The next-generation Epyc processor will also use the 7nm process, and is currently undergoing validation before being sampled to customers later this year and going on sale in 2019.
