Speedster7t FPGAs

Speedster®7t FPGAs are optimized for high-bandwidth workloads and eliminate the performance bottlenecks associated with traditional FPGAs.

The Speedster7t FPGA family is optimized for high-bandwidth workloads and eliminates the performance bottlenecks associated with traditional FPGAs. Built on the TSMC 7nm FinFET process, Speedster7t FPGAs feature a revolutionary new 2D network-on-chip (2D NoC), an array of new machine learning processors (MLPs) optimized for high-bandwidth and artificial intelligence/machine learning (AI/ML) workloads, high-bandwidth GDDR6 interfaces, 400G Ethernet and PCI Express Gen5 ports. The 2D NoC connects all of the interfaces to over 80 access points in the FPGA fabric to deliver ASIC-level performance while retaining the full programmability of FPGAs. Get started today with the VectorPath accelerator card, featuring the Speedster7t FPGA.
