NVIDIA’s GeForce RTX 4080 graphics card has received a brand new spec update from leaker, Kopite7kimi, who stories even quicker GDDR6X reminiscence.

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

According to the leaker, many of the specs for the NVIDIA GeForce RTX 4080 graphics card stay the identical and the one factor that has modified is the reminiscence spec and the facility design. It appears like NVIDIA can be leveraging from Micron’s quicker GDDR6X reminiscence modules, with the 4080 reportedly getting 23 Gbps dies. This spec update has additionally resulted in a barely greater TBP, moving as much as 340W from the earlier 320W determine.

Let’s make some updates.

NVIDIA GeForce RTX 4080 ‘Expected’ Specifications

The NVIDIA GeForce RTX 4080 is predicted to make the most of a cut-down AD103-300 GPU configuration with 9,728 cores or 76 SMs enabled of the whole 84 models whereas the earlier configuration supplied 80 SMs or 10,240 cores. While the complete GPU comes full of 64 MB of L2 cache and as much as 224 ROPs, the RTX 4080 would possibly find yourself with 48 MB of L2 cache and decrease ROPs too as a result of its cut-down design. The card is predicted to be based mostly on the PG136/139-SKU360 PCB.

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

As for reminiscence specs, the GeForce RTX 4080 is predicted to rock 16 GB GDDR6X capacities which might be mentioned to be adjusted at 23 Gbps speeds throughout a 256-bit bus interface. This will present as much as 736 GB/s of bandwidth. This continues to be a tad bit slower than the 760 GB/s bandwidth supplied by the RTX 3080 because it comes with a 320-bit interface however a lowly 10 GB capability. To compensate for the decrease bandwidth, NVIDIA may very well be integrating a next-gen reminiscence compression suite to make up for the 256-bit interface.

For energy, the TBP is now set to be rated at 340W, a 20W improve from the earlier 320W spec that we received. This brings the TBP to the identical ballpark as the prevailing RTX 3080 graphics card (as much as 350W). Now it’s not identified whether or not the opposite RTX 40 collection graphics playing cards can even be getting the quicker GDDR6X reminiscence remedy however we all know that Micron has commenced full mass manufacturing of as much as 24 Gbps GDDR6X reminiscence modules so that they must go someplace.

  • NVIDIA GeForce RTX 4080 “Expected” TBP – 340W
  • NVIDIA GeForce RTX 3080 “Official” TBP – 350W
