The memory speed of the RTX 4080 graphics card reaches 23 Gbps
Nvidia’s RTX 4080 graphics card is a member of the RTX 40 series, about which a lot of information has been published recently. Yesterday, a new update of the technical specifications of this card was shared by Kopite7kimi, which shows that the future graphics card of the green team will have a much faster memory speed. Stay with Lion Tech.
According to this source, most of the specifications of the RTX 4080 graphics card that have been published in the cyberspace for the past few weeks have remained the same, and the only thing that has changed is the VRAM memory speed and thermal power specifications. Accordingly, Nvidia is expected to use Micron’s faster GDDR6X memory for this model.
The memory speed of the RTX 4080 graphics card reaches 23 Gbps
According to the reports, the memory speed of the RTX 4080 card is about 23 Gbps, and it was also said that its thermal power has now increased from 320 watts to 340 watts. In his latest tweet, Kopite7kimi introduced the updated technical specifications of this card: “This card uses the AD103-300-A1 graphics processor along with 16 GB of GDDR6X RAM with a speed of 23 Gbps and a thermal power of 340 watts.”
The RTX 4080 is expected to be equipped with 16GB of GDDR6X memory and a 256-bit interface bus. Finally, you can compare the technical specifications of RTX 4080 Ti and RTX 4080 compared to the powerful graphics card of the previous generation:
