Nvidia’s next-generation Quadro RTX Ampere GPU boasts 48GB of GDDR6 memory

Leaks of Nvidia’s Ampere power Quadro RTX graphics cards have emerged, allegedly using Nvidia’s full GA102 graphics core to offering the workstation market more CUDA cores than the company’s recently announced RTX 3090 graphics card. 

This new Quadro RTX graphics card will feature a total of 10720 CUDA cores, 256 more than an RTX 3090, and 48GB of GDDR6 memory. No, that wasn’t a type, this Quadro graphics card will not use Micron’s GDDR6X memory, giving this unnamed Ampere Quadro RTX graphics card more CUDA cores and memory capacity than an RTX 3090 but less total memory bandwidth.   

We have already reported on Micron’s GDDR6X memory modules, and how these modules will not ship in 18Gb (2GB) forms until early 2021. This means that a 48GB graphics card is not possible over a 384-bit memory bus using GDDR6X memory, a factor which has forced Nvidia tp utilise slower GDDR6 memory modules. 

For Quadro graphics card, capacity trumps bandwidth, though it is likely that Nvidia will release faster Quadro RTX graphics cards in 2021 once faster 2GB GDDR6X memory modules become readily available. We have previously speculated that these chips could also be used to create faster versions of Nvidia’s RTX 3090 graphics card.
