Dual-width PCIe FPGA Board
Achronix Speedster7t FPGA board with GDDR6 and QSFP-DD
Features
QSFPs for 1x 400G or 6x 100G
8GB GDDR6 up to 512GB/s
7nm FPGA with 56Gbps SERDES
Overview
The S7t-VG6 offers a 7nm Achronix FPGA that is optimized for high-speed networking and fast, high-capacity memory access. Featuring a QSFP-DD (double-density) cage, the board supports up to 1x 400GbE or 4x 100GbE using the 56G PAM4-enabled Speedster®7t device. An additional QSFP port supports 2x 100GbE, and a 4x MCIO connector supports NVMe attached storage. Sixteen channels of GDDR6 graphics DRAM handle high-bandwidth memory requirements, providing up to 512GB/s.
The FPGA offers large logic and memory resources—up to 692K 6-input lookup tables (LUTs), and 189 Mb embedded RAM. It also provides 2,560 MLPs (machine-learning blocks).
