![]() Of course, the fastest memory you can get on an FPGA continues to be the local SRAM embedded in the programmable-logic fabric. There’s one overriding reason to add HBM to an FPGA: speed. These are the same in-package DRAM stacks being used to boost performance in the Fourth Generation Intel Xeon Scalable “Sapphire Rapids” CPUs and the Intel Ponte Vecchio GPU. The Agilex M-Series FPGAs incorporate the latest, fastest, 3 rd -generation HBM2e DRAM stacks. Intel’s first-generation FPGA family with integrated HBM2 DRAM stacks were the Intel Stratix 10 MX FPGAs, announced in late 2018. Xilinx announced its first FPGAs with integrated HBM, the Virtex UltraScale+ HBM FPGAs, in late 2016, although parts didn’t appear until early 2018. Both Intel and AMD-Xilinx have offered such devices for a few years. FPGAs with integrated HBM DRAM stacks are not new. ![]() Some of the FPGAs in the Agilex M-Series also incorporate integrated High Bandwidth Memory (HBM) DRAM stacks. ![]() Intel has just introduced the Agilex M-Series FPGAs with support for PCIe Gen5, Optane persistent memory, CXL, and high-speed Ethernet. ![]()
