JEDEC officially publishes their HBM3 standard - More bandwidth than an RTX 3080 on a single chip

HBM3 promises insane bandwidth levels for future devices

JEDEC has today published their HBM3 memory standard, updating the High Bandwidth Memory (HBM) standard to deliver higher data rates, higher memory densities and boosted energy efficiency. 

With per module capacities 64GB being planned and per-module bandwidth levels of 819GB/s, HBM3 offers users larger capacities and 78% more bandwidth than HBM2E.

For context, Nvidia's RTX 3080 offers users 760 GB/s of memory bandwidth with 10GB of GDDR6X memory over a 320-bit memory bus. A single HBM3 module can provide users with more bandwidth and much higher memory capacities than GDDR6/GDDR6X-based solutions, and HBM memory solutions often use more than one HBM memory module. In short, HBM3 offers users insane levels of memory bandwidth. 

At launch, first-generation HBM3 memory modules will likely ship with 16Gb (2GB) memory layers, enabling the creation of 24GB HBM3 memory stacks/modules in a 12-high TSV stack. Larger 32Gb (4GB) memory layers are planned, as are 16-high TSV stacks. This will enable the creation of 64GB HBM3 modules in the future. 

Memory bandwidth is critical for many semiconductor products, especially within the data centre, machine learning, and high-end FPGA/ASIC markets. This factor alone makes HBM3 memory a worthwhile investment for most major semiconductor companies. You can be sure that we will see new machine learning products with HBM3 memory over the next few years, as all bandwidth-constrained products will see HBM3 memory as an avenue towards increased product performance.

Press Release - JEDEC Publishes HBM3 Update to High Bandwidth Memory (HBM) Standard

JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, today announced the publication of the next version of its High Bandwidth Memory (HBM) DRAM standard: JESD238 HBM3, available for download from the JEDEC website. HBM3 is an innovative approach to raising the data processing rate used in applications where higher bandwidth, lower power consumption and capacity per area are essential to a solution's market success, including graphics processing and high-performance computing and servers.

Key attributes of the new HBM3 include:

- Extending the proven architecture of HBM2 towards even higher bandwidth, doubling the per-pin data rate of HBM2 generation and defining data rates of up to 6.4 Gb/s, equivalent to 819 GB/s per device
- Doubling the number of independent channels from 8 (HBM2) to 16; with two pseudo channels per channel, HBM3 virtually supports 32 channels
- Supporting 4-high, 8-high and 12-high TSV stacks with provision for a future extension to a 16-high TSV stack
- Enabling a wide range of densities based on 8Gb to 32Gb per memory layer, spanning device densities from 4 GB (8Gb 4-high) to 64 GB (32Gb 16-high); first generation HBM3 devices are expected to be based on a 16Gb memory layer
- Addressing the market need for high platform-level RAS (reliability, availability, serviceability), HBM3 introduces strong, symbol-based ECC on-die, as well as real-time error reporting and transparency
- Improved energy efficiency by using low-swing (0.4 V) signaling on the host interface and a lower (1.1 V) operating voltage
"With its enhanced performance and reliability attributes, HBM3 will enable new applications requiring tremendous memory bandwidth and capacity," said Barry Wagner, Director of Technical Marketing at NVIDIA and JEDEC HBM Subcommittee Chair.

Industry Support

"HBM3 will enable the industry to reach even higher performance thresholds with improved reliability and lower energy consumption," said Mark Montierth, vice president and general manager of High-Performance Memory and Networking at Micron. "In collaborating with JEDEC members to develop this specification, we leveraged Micron's long history of delivering advanced memory stacking and packaging solutions to optimize market-leading computing platforms."

"With continued advancements in HPC and AI applications, demands for higher performance and improved power efficiency has been growing more than ever before. With the current release of the HBM3 JEDEC standard, SK hynix is pleased to be able to provide a memory to our customers that has the highest bandwidth and the best power efficiency existing today with added robustness through adoption of an enhanced ECC scheme. SK Hynix is proud to be part of JEDEC and is thereby excited to be able to continue to build a strong HBM eco-system together with our industry partners, and to provide both ESG and TCO values to our customers", said Uksong Kang, Vice President of DRAM Product Planning at SK hynix.

"Synopsys has been an active contributor of JEDEC for more than a decade, helping to drive development and adoption of the most advanced memory interfaces like HBM3, DDR5 and LPDDR5 for a range of emerging applications," said John Koeter, Senior Vice President of Marketing and Strategy for IP at Synopsys. "The Synopsys HBM3 IP and verification solutions, already adopted by leading customers, accelerate the integration of this new interface into high-performance SoCs and enable development of multi-die system-in-package designs with maximum memory bandwidth and power-efficiency."

Really only comes down to cost for consumer cards to make sense. If it costs about the same then the card makers should all do it. Less dies needed to reach the same amount of memory also means less power consumption, and considering gddr6 takes quite a bit of energy to run, could free up ample energy better used for other areas.Quote
