Why it issues: SK Hynix has launched what it claims is the business’s greatest performing GDDR7 graphics reminiscence, boasting considerably improved working speeds and energy effectivity in comparison with the earlier era. The reminiscence maker mentioned its new GDDR7 provides an working velocity of 32Gbps – a 60 p.c enchancment over GDDR6 – with the potential to achieve as much as 40Gbps beneath the appropriate circumstances.
When paired with a high-end GPU, SK Hynix says the reminiscence can course of greater than 1.5 TB of information per second.
A brand new packaging expertise, in the meantime, is claimed to boost energy effectivity by greater than 50 p.c over its predecessor. By rising the variety of heat-dissipating substrate layers from 4 to 6, SK Hynix was capable of scale back thermal resistance by 74 p.c – all with out rising the reminiscence’s footprint.
SK Hynix is one in all a number of reminiscence makers engaged on GDDR7.
Samsung was the primary to announce a GDDR7 reminiscence product, doing so in July 2023. On the time, the corporate mentioned its providing be capable of hit speeds of as much as 32Gbps and can be 20 p.c extra energy environment friendly than current GDDR6. Samsung additionally claimed a 70 p.c discount in thermal resistance due to a brand new epoxy molding compound.
Simply final month, Micron began sampling its GDDR7 chips to business companions. Like the opposite choices, Micron’s tech provides 32Gbps and over 1.5 TB/s of bandwidth.
Choose Nvidia GeForce RTX 5000 graphics playing cards are anticipated to ship with GDDR7 reminiscence, however not all fashions. In accordance with a June report, the RTX 5060 and / or the RTX 5050 will solely help GDDR6. All different playing cards within the client lineup are anticipated to incorporate GDDR7.
SK Hynix mentioned it expects to begin mass manufacturing of its GDDR7 within the third quarter of this yr. Nvidia’s RTX collection is due out someday within the fourth quarter, however it will not be the one platform to get sooner GDDR7 chips. AI functions will even profit from the sooner reminiscence in due time.
