High Bandwidth Memory (HBM) is a computer memory interface for 3D-stacked synchronous dynamic random-access memory (SDRAM) initially from Samsung, AMD and SK Hynix.

Dec 1, 2024 · HBM vs. DDR. HBM uses 3D stacking, where multiple memory dies are placed on top of each other, connected vertically using TSVs (Through-Silicon Vias). This compact design saves space and boosts performance. DDR, on the other hand, is a 2D memory design, where all chips are laid out side-by-side.

Sep 9, 2021 · In this article, we will take the opportunity of talking about HBM to talk about the characteristics and usage scenarios of this kind of memory, and whether it will replace the very common DDR memory on computers in the future.

High-bandwidth memory is a type of computer memory that is optimized for fast data transfer and reduced power consumption. It has become increasingly used and deployed alongside high-performance computing (HPC) and artificial intelligence workloads …

Jan 20, 2015 · HBM is the "middle" option as far as cost and bandwidth -- it's not as cheap as Wide I/O, or as power efficient, but it's explicitly designed for high performance GPU environments and still...

Jan 9, 2018 · Comparing DDR and HBM. How does the connectivity of DDR and HBM compare? With DDR4 and 5, the DRAM die are packaged and mounted on small PCBs which become dual inline memory modules (DIMMs), and then connected to a …

HBM offers exceptional transfer rates owing to short data paths in its 3D stacked architecture and high-speed Through-Silicon Vias (TSVs). Compared to traditional DRAM, which may reach transfer rates of about 8 to 14 Gbps, HBM can boast rates well above 100 Gbps.

Apr 15, 2021 · HBM stands for high bandwidth memory and is a type of memory interface used in 3D-stacked DRAM (dynamic random access memory) in some AMD GPUs (aka graphics cards), as well as the server,...

Feb 24, 2025 · HBM is a memory technology that takes advantage of newer chip fabrication techniques to allow for more bandwidth and more bandwidth/watt than traditional DDR implementations. Memory manufacturer uses stacked die and through silicon via chip fabrication techniques to stack multiple smaller DDR-based memories into a …

From an application point of view, DDR based DRAM DIMMs are still used as the main system memory for most client and server systems, while HBM is used for applications that require low latency, high bandwidth but at the cost of a lower capacity.
