Disintegrating Manycores
Isidor R. Brkić, Mark C. Jeffrey · 2023
The economics of Moore's Law are stumbling, so vendors of many-core architectures are transitioning from single-die monolithic designs to multi-chiplet disintegrated systems within a package. Disintegration lowers cost for the same number of cores but bottlenecks the interconnect. Ideally, disintegration should increase performance per dollar: cost savings should outweigh the disintegration slowdown. Although industry has reported cost savings, the performance penalty of disintegration is not well studied.
