李康旭解释，标准HBM 和定制化HBM 核心芯片相同，但是Base Die（基础芯片）不同，主要是再加入客户的IP，芯片效率也可能更高。另据韩媒报道，SK 海力士将小芯片技术（chiplet）导入存储控制器（memory controller）。对此，李康旭表示目前控制器是在单芯片（SoC）中，但未来会针对小芯片封装技术，结合存储控制器。除了...
Our High-Bandwidth Memory (HBM) controller IP provide high-bandwidth, low-latency memory performance for AI/ML, graphics and HPC applications.
也许是Die Size过于庞大,预留的12个HBM Controller,仅有10个被启用,非满血的6个HBM2e。 HBM3 2023年年底,AMD正式发布了MI300X,搭载了8个HBM3 12Hi 24GB Stacks,总容量192GB,总带宽达到了惊人的5.3TB/s。 HBM3e H200尚未问世,因该是H100的完全体版本,采用6个HBM3e 12Hi 24GB Stacks,总带宽4.8 TB/s。
The Rambus HBM3E controller core is designed for use in applications requiring high memory bandwidth and low latency including AI/ML, HPC, advanced data center workloads and graphics.
此外,RGBCG和RCB的方式性能基本是最好的,也就是Xilinx HBM/DDR controller默认的设置下,连续读写性能就是最好的,也就是尽量Bank Group最低位滚动,Row尽量在最高位滚动。当Stride变大时,即接近“随机读写”此时性能变差。 具体实测性能 测试板卡是FPGA boardAlevo U280,应用HBM2e,理论最大带宽460GB/s,2个DDR...
