- AMD introduces Solarflare X4 NICs designed for low-latency trading applications.
- Two models available: X4522 with dual SFP56 (up to 50GbE per port) and X4542 with dual QSFP56 (up to 100GbE per port).
- Features CTPIO (Cut Through Programmed Input Output) for reduced latency by transmitting packets before full PCIe bus traversal.
- Solarflare NICs are specialized for high-frequency trading, not standard enterprise or AI networking.
- AMD's acquisition history includes Solarflare (2019 via Xilinx) and Pensando, enhancing its NIC IP portfolio.
- New CyPerf network testing suite to be featured in future reviews, including high-end Keysight tools.
- Solarflare was a leading financial trading NIC provider in the 2010s, now under AMD's umbrella.
- Criticism noted for lack of detailed differentiation from other NICs and unclear QSFP56 port specifications.
