Transitioned from NRZ (Non-Return to Zero) to PAM4 (Pulse Amplitude Modulation with 4 levels). AI training clusters rely on massive data movement
Organizes data into fixed-size Flow Control Units (FLITs) to support heavy error correction. especially in GPU-accelerated computing.
: AI and ML applications require high-speed data processing and low latency, areas where PCIe 6.0 can provide significant benefits, especially in GPU-accelerated computing.
