Benchmarks: Memory
Memory bandwidth is lopsided on the Ryzen 7 3700X platform, and this is due to the way the chip is constructed. To recap, each Core Complex Die (CCD) is connected to the chiplet I/O die (cIOD) via Infinity Fabric that reads at 32 bytes per cycle but only writes at 16. This is why Ryzen 7 3700X's single-CCD design suffers a drop in write bandwidth by almost half. Our tests have shown little real-world impact, and we're pleased to see the AlphaSync ship with fast 3,200MHz modules as standard.
