NVIDIA GeForce RTX 4090/4080 to Feature up to 24 GB of GDDR6X Memory and 600 Watt Board Power

After the data center-oriented Hopper architecture launch, NVIDIA is slowly preparing to transition the consumer section to new, gaming-focused designs codenamed Ada Lovelace. For starters, the source claims that NVIDIA is using the upcoming GeForce RTX 3090 Ti GPU as a test run for the next-generation Ada Lovelace AD102 GPU. Thanks to the authorities over at Igor's Lab, we have some additional information about the upcoming lineup. We have a sneak peek of a few features regarding the top-end GeForce RTX 4080 and RTX 4090 GPU SKUs. According to Igor's claims, NVIDIA is testing the PCIe Gen5 power connector and wants to see how it fares with the biggest GA102 SKU - GeForce RTX 3090 Ti.

Additionally, we find that the AD102 GPU is supposed to be pin-compatible with GA102. This means that the number of pins located on GA102 is the same as what we are going to see on AD102. There are 12 places for memory modules on the AD102 reference design board, resulting in up to 24 GB of GDDR6X memory. As much as 24 voltage converters surround the GPU, NVIDIA will likely implement uP9512 SKU. It can drive eight phases, resulting in three voltage converters per phase, ensuring proper power delivery. The total board power (TBP) is likely rated at up to 600 Watts, meaning that the GPU, memory, and power delivery combined output 600 Watts of heat. Igor notes that board partners will bundle 12+4 (12VHPWR) to four 8-pin (PCIe old) converters to enable PSU compatibility.

Legacy-ZANo hidden surprises? I see I need to install a certificate, and the program uses a silent updater, not sure how I feel about that. :)
Linus did a video about DLSS Swapper, that was how I knew about it, so I think they verified that it's safe to use :D
MusselsThose rumours and early results are always about stupid scenarios, oh yes its twice as fast - at 8K with RTX on and DLSS (2FPS to 4FPS)


This is also going to be something stupid like a 600W capable power connector, not that the GPU's use it
I have huge doubt about air cooler dissipating 500W of heat at any sane volume, even the massive AIB 3090 models like the MSI SuprimX and Gigabyte Xtreme have a hard time cooling 420-480W. So yeah the 4090 might top out at 450W and Nvidia holding the 4090Ti trump card with >500W TDP until they know how RDNA3 would perform.

If the 4080 can offer 50% higher FPS over the 3090 and use 320W, it would already be overkill for 4K + RT DLSS gaming.

Vayra86Also, lower SKUs arent all that efficient at all, the 104 also got its share of TDP bumps
Isnt efficiency measured by performance / watt? Just because it got a tdp bump doesnt mean it has lower efficiency, right? My 3090 is way more efficienct than my 1080ti for example
LycanwolfenWho remembers when Nvidia said they were going to make video cards have more graphic power while using less real power. That was the pitch 5 years ago. And their roadmap showed it less and less power hungry video card with more output for graphic power. Strange how that all went to the trash can.
No it didnt. A 3090 at 250w gets more work done than a 1080ti at 250w. I think you are confusing efficiency with power consumption. A gpu can consume 10.000 watts and still be efficient

Haha, imagine the size of cases to house this beast!

DeeJay1001Electricity is cheap and plentiful here on the Eastern side of the US. I pay well under 10c per kW/h. My usage is significantly higher than other homes in mu development and I've never heard a peep from the supplier or line provider.
And chances are as long as you keep paying the bill you won't hear from them. What did you think your lines/power company gives a damn about how much power you're using at home pfffft nope they couldn't give two shits it's all money to them until what you're doing causes problems for your neighbours

Everytime an article is posted on this website mentioning "board power" the entire community mistakes it for stock power draw.

That 600W can be from a single 12pin connector.

Just wondering how hot that connector can get with the maximum draw.
