NVIDIA seems to have modified its internal TBP figures for its upcoming GeForce RTX 4080 & RTX 4070 graphics cards.

NVIDIA GeForce RTX 4080 & RTX 4070 Updated To Lower TBP Specs, Now Rumored at 320W & 285W

The latest rumor comes from Kopite7kimi who has reported that NVIDIA's GeForce RTX 4080 & RTX 4070 graphics cards will now feature a lower TBP (Total Board Power) figure versus what the green team had planned previously. It is stated that the GeForce RTX 4080 would feature a TBP of 320W & the RTX 4070 would feature a TBP of 285W however one should always remember that these specs aren't set in stone and while they are based on actual internal changes, the final retail specs could always change.

We can expect RTX 4080 with 320W and RTX 4070 with 285W.

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.

As for memory specs, the GeForce RTX 4080 is expected to rock 16 GB GDDR6X capacities that are said to be adjusted at 21 Gbps speeds across a 256-bit bus interface. This will provide up to 672 GB/s of bandwidth. For power, the TBP is now set to be rated at 320W, a 100W decrease from the previous 420W spec that we got. This brings the TBP to the same ballpark as the existing RTX 3080 graphics card (320W too).
