Now that JEDEC has revealed specification of GDDR7 reminiscence, reminiscence producers are starting to announce their preliminary merchandise. The first out of the gate for this era 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 knowledge switch fee and a quicker model working at as much as 32 GT/s knowledge switch fee (which is in step with preliminary components that Samsung introduced in mid-2023). The chips characteristic a 512M x32 group and are available a 266-pin FBGA packaging. The chips are already sampling, so Samsung’s clients – 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 (eight GB) and knowledge switch charges of 48 GT/s. Meanwhile, first era GDDR7 chips (as introduced to date) will characteristic a fairly reasonable capability of 16 Gbit (2 GB) and an information switch fee of as much as 32 GT/s.
Performance-wise, the primary era of GDDR7 ought to present a big enchancment in reminiscence bandwidth over GDDR6 and GDDR6X. However capability/density enhancements won’t come till reminiscence producers transfer to their subsequent era EUV-based course of nodes. As a consequence, the primary GDDR7-based graphics playing cards are unlikely to sport any reminiscence capability enhancements. Though trying a bit farther down the street, Samsung and SK Hynix have beforehand advised Tom’s Hardware that they intend to achieve mass manufacturing of 24 Gbit GDDR7 chips in 2025.
Otherwise, it’s noteworthy that SK Hynix additionally demonstrated its GDDR7 chips at NVIDIA’s GTC final week. So Samsung’s competitors needs to be shut behind in delivering samples, and finally mass manufacturing reminiscence.
