AMD's Pre-Zen Interconnect: Testing Trinity's Northbridge
Today, AMD’s Infinity Fabric interconnect is ubiquitous across the company’s lineup.
AMD’s engineers likely didn’t envision needing to tightly integrate a GPU during Athlon 64’s development, so the interconnect was designed to tie together a few CPU cores and service memory requests with low latency. Here I’ll be looking into AMD’s second generation iGPU interconnect with the A8-5600K, a slightly cut-down Trinity implementation with four Terascale 3 SIMDs enabled and CPU boost clocks dropped from 4.2 to 3.9 GHz. Trinity’s crossbars and separate coherent/non-coherent iGPU links may lack elegance and sophistication compared to modern designs but it was sufficient to let AMD get started with powerful iGPUs in the early 2010s.
