Now that JEDEC has printed specification of GDDR7 reminiscence, reminiscence producers are starting to announce their preliminary merchandise. The primary out of the gate for this technology is Samsung, which has has quietly added its GDDR7 merchandise to its official product catalog.
For now, Samsung lists two GDDR7 units on its web site: 16 Gbit chips rated for an as much as 28 GT/s information switch price and a sooner model working at as much as 32 GT/s information switch price (which is in keeping with preliminary components that Samsung introduced in mid-2023). The chips characteristic a 512M x32 group and are available in a 266-pin FBGA packaging. The chips are already sampling, so Samsung’s prospects – GPU distributors, AI inference distributors, community product distributors, and the like – ought to have already got GDDR7 chips of their labs.
The GDDR7 specification guarantees the utmost per-chip capability of 64 Gbit (8 GB) and information switch charges of 48 GT/s. In the meantime, first technology GDDR7 chips (as introduced to date) will characteristic a quite average capability of 16 Gbit (2 GB) and an information switch price of as much as 32 GT/s.
Efficiency-wise, the primary technology of GDDR7 ought to present a big enchancment in reminiscence bandwidth over GDDR6 and GDDR6X. Nevertheless capability/density enhancements won’t come till reminiscence producers transfer to their subsequent technology EUV-based course of nodes. Because of this, the primary GDDR7-based graphics playing cards are unlikely to sport any reminiscence capability enhancements. Although trying a bit farther down the street, Samsung and SK Hynix have beforehand informed Tom’s {Hardware} that they intend to succeed in mass manufacturing of 24 Gbit GDDR7 chips in 2025.
In any other case, it’s noteworthy that SK Hynix additionally demonstrated its GDDR7 chips at NVIDIA’s GTC final week. So Samsung’s competitors ought to be shut behind in delivering samples, and finally mass manufacturing reminiscence.
