AMD’s use of the chiplets small chip design on the 7nm Zen2 architecture Issmall processor is a major amd initiative to make it easier to build a 64-core 128 threaded processor, an implementation that is also a credit to multiple teams of geometric AMD. So what are the benefits of this design? At the recent ISSCC conference, AMD released data that compared 7nm Zen2 cost data in different core configurations.
First look at the desktop version, if the 16-core 32-threaded Ryzen 3 generation is the 100% benchmark, then the cost of a 16-core processor with native core sits will be more than 2, at least twice the cost.
If it is the EPYC Dragon processor, then the more core number, the more the cost advantage is obvious, 64 core 7nm rye dragon as the benchmark, then the cost of 48 core is 0.9, and the cost of the original 48 core design is at least 1.9, is still double the level.
Of course, with the reduction of the core number, the cost benefit will also decline, the cost of desktop 8 core is similar to the native core design, 16 core and above will have a more obvious cost reduction.
AMD unveiled the secrets of 64-core small-chip design at the ISSCC 2020 conference late last month, in which AMD thanked the global research and development team on the last page, referring to Austin, Bangalore, Boston, Fort Collins, Hyderabad, Wanjin, Santa Clara and Shanghai.
Among them, Austin is AMD’s original headquarters, is also the core of the research and development team, Bangalore, Hyderabad is India, Wanjin City is Canada, Shanghai is China, Santa Clara is now AMD headquarters.
As a result, the complexity of modern CPUs is not something that can be done by one or two teams, and companies like AMD need multiple teams from around the world to work together.
