Do chiplets underperform compared to a monolithic die?
- wmf 6y agoYes.
- monocasa 6y agoPretty much any time you have signals going off chip, you lose out on both bandwidth and latency.
- Symmetry 6y agoAll things being equal a chiplet design will underperform a monolithic die. But we've already seen the benchmarks on the performance of Milan so looking at chiplets versus monolithic is mostly about considering AMD's strategy and constraints rather than how the chips perform.
- gsnedders 6y agoAs others have said, in isolation and perfect manufacturing capability, it's absolutely true a monolithic die is better. However, because each die is smaller, you can be more aggressive with your binning, potentially having a larger number of chips which you can bin into a higher frequency bucket. Ultimately, it's a matter of trade-offs, and what's right in one place might be wrong in another (see, e.g., AMD manufacturing mobile APUs on monolithic dies versus all their desktop and server parts using chiplets). We are seeing more of the industry moving to chiplets and similar solutions, notably Intel with their tiles.
