Micron Confirms Next-Gen NVIDIA Ampere Memory Specifications

Micron have spilled the beans on a minimum of some specs for NVIDIA’s next-gen Ampere graphics playing cards. In a brand new tech transient posted by the corporate earlier this week, hidden away behind Micron’s market outlook, technique and positioning, lie some secrets and techniques NVIDIA won’t be too eager to see divulged earlier than their #theultimatecountdown occasion.

Under a comparability on extremely bandwidth options, segregated into the GDDR6X column, Micron lists a next-gen NVIDIA card underneath the “RTX 3090” product identify. According to the spec sheet, this card contains a whole reminiscence capability of 12 GB GDDR6X, achieved via 12 reminiscence chips with a 384-bit broad reminiscence bus. As we noticed immediately, solely 11 of those appear to be populated on the RTX 3090, which, when paired with specs for the GDDR6X reminiscence chips being able to 19-21 Gbps speeds, brings whole reminiscence subsystem bandwidth in direction of the 912 – 1008 GB/s vary (utilizing 12 chips; 11 chips leads to 836 GB/s minimal). It’s attainable the RTX 3090 product identify is not an official NVIDIA product, however fairly a Micron-guessed chance, so do not have a look at it as factual illustration of an upcoming graphics card. One different attention-grabbing side from the tech transient is that Micron expects their GDDR6X know-how to allow 16 Gb (or 2 GB) density chips with 24 Gbps bandwidth, as early as 2021. You can learn over the tech transient – which mentions NVIDIA by identify as a improvement associate for GDDR6X – by following the supply hyperlink and clicking on the “The Demand for Ultra-Bandwidth Solutions” doc.
