NVIDIA GeForce RTX 3090 and 3080 Specifications Leaked
Just ahead of the September launch, specifications of NVIDIA's upcoming RTX Ampere lineup have been leaked by industry sources over at VideoCardz. According to the website, three alleged GeForce SKUs are being launched in September - RTX 3090, RTX 3080, and RTX 3070. The new lineup features major improvements: 2nd generation ray-tracing cores and 3rd generation tensor cores made for AI and ML. When it comes to connectivity and I/O, the new cards use the PCIe 4.0 interface and have support for the latest display outputs like HDMI 2.1 and DisplayPort 1.4a.
The GeForce RTX 3090 comes with 24 GB of GDDR6X memory running on a 384-bit bus at 19.5 Gbps. This gives a memory bandwidth capacity of 936 GB/s. The card features the GA102-300 GPU with 5,248 CUDA cores running at 1695 MHz, and is rated for 350 W TGP (board power). While the Founders Edition cards will use NVIDIA's new 12-pin power connector, non-Founders Edition cards, from board partners like ASUS, MSI and Gigabyte, will be powered by two 8-pin connectors. Next up is specs for the GeForce RTX 3080, a GA102-200 based card that has 4,352 CUDA cores running at 1710 MHz, paired with 10 GB of GDDR6X memory running at 19 Gbps. The memory is connected with a 320-bit bus that achieves 760 GB/s bandwidth. The board is rated at 320 W and the card is designed to be powered by dual 8-pin connectors. And finally, there is the GeForce RTX 3070, which is built around the GA104-300 GPU with a yet unknown number of CUDA cores. We only know that it has the older non-X GDDR6 memory that runs at 16 Gbps speed on a 256-bit bus. The GPUs are supposedly manufactured on TSMC's 7 nm process, possibly the EUV variant.

The 2080Ti for example is rated for 1545MHz and you'll never see one under 1750MHz in actual games, unless there is something broken with the cooling.
Finally, now, all monitors that requires a huge bandwidth will come with hdmi 2.1.
As for Tsmc 5nm supers, that's dreamy IMHO.
Soooo 300 watts max some said yesterday, you can't exceed two 8 pins at 300 they said, balls I said you wouldn't need heavier gauge wire.
350 watts at base clocks, what's the max OC pull on that 500?, We'll see.
I own a Vega 64 ,course you can, and I'll take this opportunity to welcome Nvidia back in to forman grill territory, it's been lonely here for two years:p
1. Clock speed. 1710-1545, >10% clock rate. That right there explains MOST of the power difference, as well as the efficiency differences
2. RTX core changes. You can call this IPC, if you wanted to, if my understanding is right. Supposedly the RTX cores are hugely more efficient.
3. Heat. I am only just now experiencing how much heat a video card is going to push into the room. Let's put it this way. You can buy a ~$300 air conditioning unit that exhausts to the outside. Those can put out roughly 8000-12000 BTU of heat (per hour). In my experience, this can cool my bedroom from 80F to 70F in about 10 minutes, Your mileage will vary. A simple conversion shows 320watts is roughly 1,091.9 BTU. If my uneducated, guesswork/screwed up math is close to right, that's roughly 10 degrees per hour that needs to be cooled, or vented out of the room. that's on top of what your computer puts out without the graphics card. I know my room gets HOT if I run games for a few hours solid. it's going to be roughly 30% more heat from the video card. And I'm still running a 10-series card.

Now, I'm really excited for RDNA2.... But, I did just get a 5700xt last November, so maybe I actually just might check out the Xbox Series X in all honesty.... Never been excited about consoles, but it's definitely different this time around
This is about high end gaming and more Vram to work with is better, higher resolution textures and shadow quality and other stuff.
10gb on a new flagship 3080 is..... just extremely lackluster.
Like I said its like Big N is following Big I and just sell us a nothingburger due to lack of competition in these price brackets.
