Or to put it in layman's terms: AMD processors will continue to have pins on the back of the CPU.
AMD's "Summit Ridge" CPUs will come with up to 8 cores and 16 threads and provide 40% more instructions per clock than AMD's previous CPU architectures, meaning that this CPU will be offering significantly higher performance than AMD's current CPU lineup, potentially making them competitive with Intel again in the high-end consumer market. The CPU will be coming to the AM4 platform, which will support DDR4 memory, allowing AMD's Zen CPUs to use faster memory with lower power consumption than AMD's current CPUs.
