HBM3 And DDR5
#1

  • HBM3 should come in 2019 at the earliest
  • HBM2 has had issues with yield, which could get worse with HBM3 due to greater complexity
  • DDR5 should come in 2020

Quote:GamersNexus recently received tips from a highly credible source that works at a major memory supplier. We got enough to write several stories, but we’ll start with this one:

Our present understanding is that AMD is working with at least one memory supplier to establish an on-site R&D lab at the company’s Austin campus, which is being used to research DDR5 and develop the next generation of memory. AMD is trying to beat Intel to market with DDR5, which fits the company’s history of pushing new memory standards earlier. ATi also did this with older revisions of GDDR memory.

Separately, we also learned that AMD is working on what they call “Near Memory,” or HBM being used in conjunction with future CPU components. We’re not clear presently on whether that includes desktop CPUs, but we do know that HBM for CPUs is in active R&D, and given Hades Canyon, that’s not necessarily a big surprise.

Quote:Cadence and Micron have joined forces to build the world's first working DDR5-4400 memory module. Cadence provided their DDR5 memory controller and PHY for the prototype while Micron produced the 8 Gb chips, which were manufactured under TSMC's 7 nm process. They were able to achieve 4400 megatransfers per second, which is roughly 37.5% faster than the fastest DDR4 memory that is currently on the market. Nevertheless, Marc Greenberg from Cadence emphasized that DDR5 aims to provide increased capacity solutions, more than actual performance.
...
Cadence expect DDR5-4400 to be the standard for DDR5 with DDR5-6400 coming later down the line. According to their analysis, we could see DDR5-based systems as soon as in 2019. However, they'll most likely be servers. The process of DDR5 adoption will be gradual and steady until 2021 when it starts to really ramp up. It's important to point out that the DDR5 standard isn't completed yet. JEDEC won't finalize the specifications for DDR5 until sometime this summer. Having being the first with IP for DDR5, Cadence already has its eyes set on LPDDR5 and HBM.

Quote:When discussing the upcoming release of DDR5, Ted Tsai, SP's DRAM Product Manager, added, "DDR5 is still just 'talk' at this point. The price of DDR5 will be luxury gear for heavy players only."
