NVIDIA GeForce RTX 4080 16 GB & 12 GB Cards Based on AD103 & AD104 GPUs, GALAX Waifu Cards & Up To 2685 MHz Factory Overclock Detailed
Although we have covered the NVIDIA GeForce RTX 40 series custom models in detail over here, this is the first confirmation of a manufacturer clearly listing the AD103 and AD104 GPUs for the GeForce RTX 4080 series graphics cards. So far, we only officially knew that the GeForce RTX 4090 was featuring the AD102 GPU core but the chips for the 4080 series are confirmed now. NVIDIA GeForce RTX 4080 16 GB ‘Expected’ Specifications The NVIDIA GeForce RTX 4080 16 GB graphics card will 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. The graphics card is said to offer a peak clock rate of 2505 MHz. As for memory specs, the GeForce RTX 4080 is will rock 16 GB GDDR6X capacities that are said to be adjusted at 22.5 Gbps speeds across a 256-bit bus interface. This will provide up to 720 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.
NVIDIA GeForce RTX 4080 16 GB “Expected” TBP - 320W NVIDIA GeForce RTX 3080 12 GB “Official” TBP - 350W
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). The maximum BIOS TGP is said to be rated at 516W. 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 12 GB ‘Expected’ Specifications The NVIDIA GeForce RTX 4080 will also feature a 12 GB variant that will utilize the AD104-400 GPU configuration with 7,680 cores or 60 SMs enabled which is the full-fat SKU. The GPU will be packing 48 MB of L2 cache and features a 192-bit bus interface so that’s why we are getting up to 12 GB of GDDR6X capacities. The memory is said to be running at 21 Gbps speeds for a memory bandwidth of 504 GB/s. The card is said to be clocked at a 2610 MHz boost clock however the peak frequency will be higher.
NVIDIA GeForce RTX 4080 12 GB “Expected” TBP - 285W NVIDIA GeForce RTX 3080 10 GB “Official” TBP - 320W
For power, the TBP is now set to be rated at 285W which is a 35W decrease versus the RTX 3080 10 GB model. The card is expected to offer better performance than the RTX 3080 but given the specs cut over the 4080 16 GB, there will be a big gap between both models. The maximum BIOS TGP is said to be rated at 366W.
NVIDIA GeForce RTX 40 Series Official Specs:
In addition to the NVIDIA GeForce RTX 4080 graphics card specifications, GALAX has also listed its factory overclock frequencies which offer a 3% boost in clocks. The fastest model is the RTX 4080 12 GB BOOMSTAR which has a rated factory overclock of up to 2685 MHz. What’s interesting is all cards are bundled with a 16-pin adapter that features four 8-pin connectors instead of three. While the GeForce RTX 4090 has a reference TGP of 450W, it looks like overclocked variants will require a bit more power, reaching beyond 500W and that’s where the fourth 8-pin connector comes to play. We have already reported how NVIDIA has stated that the GeForce RTX 40 series is running past 3 GHz in their labs and water block manufacturer, EK, has also pointed this out. It looks like we will be looking at some spectacular clock figures with the Ada Lovelace GPUs once they hit the road. Also, it looks like GALAX is the first to have Waifu cards available under its new Boomstar 2022 line. The graphics cards come in a white colored cooler and shroud and GALAX ships three backplates on each card and also bundles the card with paints and pallets so users can customize the cards to their liking. The GeForce RTX 4080 series graphics cards are expected to launch in November so we are likely to get more information on them in the coming weeks.
