NVIDIA GeForce RTX 4080 Graphics Card Now Expected To Feature 23 Gbps GDDR6X Memory at 340W TBP

NVIDIA GeForce RTX 4090 Rumored To Be More Than Twice As Fast As RTX 3090, RTX 4080 Goes Overboard With 420W TBP

NVIDIA's GeForce RTX 4080 graphics card has got a new spec update from leaker, Kopite7kimi, who reports even faster GDDR6X memory.

NVIDIA GeForce RTX 4080 Graphics Card Now Expected To Feature 23 Gbps GDDR6X Memory at 340W TBP

According to the leaker, most of the specifications for the NVIDIA GeForce RTX 4080 graphics card remain the same and the only thing that has changed is the memory spec and the power design. It looks like NVIDIA will be leveraging from Micron's faster GDDR6X memory modules, with the 4080 reportedly getting 23 Gbps dies. This spec update has also resulted in a slightly higher TBP, moving up to 340W from the previous 320W figure.

NVIDIA GeForce RTX 4080 'Expected' Specifications

The NVIDIA GeForce RTX 4080 is expected to utilize a cut-down AD103-300 GPU configuration with 9,728 cores or 76 SMs enabled of the total 84 units whereas the previous configuration offered 80 SMs or 10,240 cores. While the full GPU comes packed with 64 MB of L2 cache and up to 224 ROPs, the RTX 4080 might end up with 48 MB of L2 cache and lower ROPs too due to its cut-down design. The card is expected to be based on the PG136/139-SKU360 PCB.

As for memory specs, the GeForce RTX 4080 is expected to rock 16 GB GDDR6X capacities that are said to be adjusted at 23 Gbps speeds across a 256-bit bus interface. This will provide up to 736 GB/s of bandwidth. This is still a tad bit slower than the 760 GB/s bandwidth offered by the RTX 3080 since it comes with a 320-bit interface but a lowly 10 GB capacity. To compensate for the lower bandwidth, NVIDIA could be integrating a next-gen memory compression suite to make up for the 256-bit interface.

For power, the TBP is now set to be rated at 340W, a 20W increase from the previous 320W spec that we got. This brings the TBP to the same ballpark as the existing RTX 3080 graphics card (up to 350W). Now it is not known whether the other RTX 40 series graphics cards will also be getting the faster GDDR6X memory treatment but we know that Micron has commenced full mass production of up to 24 Gbps GDDR6X memory modules so they have to go somewhere.

  • NVIDIA GeForce RTX 4080 "Expected" TBP - 340W
  • NVIDIA GeForce RTX 3080 "Official" TBP - 350W

The NVIDIA GeForce RTX 4080 and RTX 4070 graphics cards will be amongst the first graphics cards besides the RTX 4090 to launch to gamers however we can't tell whether the green team plans to launch them within this year soon after RTX 4090 or wait till early next year. The RTX 4090 is so far expected to launch around October 2022.
