NVIDIA GeForce RTX 4080 at 320W & RTX 4070 at 285W TBP, Tamer & Powerful Gaming GPUs

Aug 9, 2022 13:50 EDT
Chinese GPU Supplier Rumored To Get First NVIDIA GeForce RTX 40 Graphics Cards In Less Than A Month

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.

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).

The NVIDIA GeForce RTX 4070 is expected to utilize the full-fat AD104 GPU core with 7680 cores or 60 SM units. From previous leaks, we also know that the AD104 GPU will come packed with 48 MB of L2 cache and up to 160 ROPs which is simply insane. That's a 25% increase in core count and a 12x increase in cache versus the GeForce RTX 3070 Ti which rocks the GA104 GPU core.

As for memory specs, the GeForce RTX 4070 is expected to rock 12 GB GDDR6X capacities that are said to be clocked at 21 Gbps speeds across a 192-bit bus interface for 504 GB/s bandwidth. As for power numbers, the RTX 4070 is now rated at 285W TBP which is 65W higher than the TBP of the RTX 3070. The graphics card is expected to be based on the PG141-SKU331 PCB design.

It also seems like KittYYuko is back in the leak scene on Twitter and his first new info seems to be about another Ada Lovelace AD102 GPU codenamed AD102-250 which would feature 14848 cores, a 20 GB VRAM across a 320-bit bus interface running at 21 Gbps speeds which equals to 840 GB/s of bandwidth. The card is said to utilize the PG139-SKU340 PCB. It is likely that this config may be used by an RTX 4080 Ti graphics card or a Pro variant but let's see until we get more confirmation.

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.
