Micron has quietly began quantity manufacturing of GDDR6X reminiscence chips that includes a 24 GT/s information switch price. The brand new reminiscence units are anticipated for use by a few of Nvidia’s upcoming high-end GeForce RTX 40-series graphics playing cards primarily based on the Ada Lovelace structure.
Micron’s new 24 GT/s GDDR6X chips have a capability of 16Gb (2GB) and can be utilized to construct graphics playing cards with a great deal of reminiscence onboard (by way of @Harukaze5719). It’s anticipated that these ICs shall be used for Nvidia’s GeForce RTX 4090 graphics card, carrying 24GB of GDDR6X reminiscence related to the GPU utilizing a 384-bit reminiscence bus (and due to this fact providing a peak reminiscence bandwidth of 1.152 TBps, assuming that Nvidia will use reminiscence at its highest rated velocity). Different merchandise from the lineup are rumored to make use of slower GDDR6X units with an as much as 21 GT/s information switch price.
As well as, the 24 GT/s GDDR6X reminiscence chips are projected for use by Nvidia’s next-generation flagship graphics board at present generally known as The Beast (typically known as the GeForce RTX 4090 Ti), which can carry 48GB of reminiscence on each side of the cardboard (and can doubtless be the greatest graphics card out there when it comes to uncooked efficiency within the coming months).
Nvidia is rumored to formally introduce its GeForce RTX 40-series ‘Ada Lovelace’ merchandise this fall. Subsequently, it’s about time for Micron to kick off quantity manufacturing of its next-generation GDDR6X reminiscence chips with an as much as 24 GT/s information switch price.
Neither Nvidia nor Micron have formally commented about utilization eventualities of 24 GT/s GDDR6X reminiscence chips, so take unofficial details about Nvidia’s GeForce RTX 40-series lineup with a grain of salt. In the meantime, Micron is definitely beginning manufacturing on this reminiscence that shall be utilized by one in all its shoppers. At current, the one firm to assist GDDR6X is Nvidia.
It’s noteworthy that Samsung has been sampling its 24 GT/s GDDR6 (not GDDR6X) reminiscence chips since December, 2021. So Micron has some speedy competitors.
