Possible GeForce RTX 4070 "Ada" Specs Hit the Rumor Mill
Two sets of possible specifications of the upcoming performance-segment NVIDIA GeForce RTX 4070 "Ada" graphics card has hit the rumor-mill, according to kopite7kimi, a reliable source with NVIDIA leaks. The first set of specs sees the card feature 12 GB of 21 Gbps GDDR6X memory (possibly over a 192-bit wide memory bus), as many as 7,680 CUDA cores, a typical board power of 285 W, and an internal SKU code of "PG141-SKU340/341." It makes sense for 12 GB of memory across a 192-bit memory bus to be a logical choice for NVIDIA (as opposed to the previous-gen RTX 3070 with its 8 GB of 14 Gbps GDDR6 across 256-bit); as it allows the company to achieve a 50% memory size increase gen-over-gen, while reducing the number of memory chips on the card from 8 to 6 (by using six 16 Gbit GDDR6X chips).
The second set of specs doing rounds is the "PG141-SKU336/337," consisting of 7,168 CUDA cores, 10 GB of 21 Gbps GDDR6X memory across what we're assuming could be a 160-bit wide memory bus (five memory chips), and 250 W typical board power. The same source also claims that the SKU340/341 could have a performance target of over 11000 points in Time Spy Extreme, while the SKU336/337 could be designed with at least 10000 points in mind. It's quite possible that the second configuration is that of the RTX 3060 Ti-successor SKU. Given NVIDIA's top-down approach to product launches, we could expect performance-segment SKUs only toward the end of 2022, or early-2023.

It will actually generate W just for using it...
Bye bye thermodynamics :)
i'm sure you can get even more out of it if you overclock it a bit, but power consumption would go up.
Hopefully the 4070 can beat the 7700xt, which has an even smaller 128bit bus right now, the red team is also trying to stuff more cores into their cards as well.
Ty.
6600 XT 237 mm² 2048
7600 XT 203 mm² 4096 ALu everything esle the same 32MB 64 Rops 128 bit
See what they did there, 4096 new Shading Units = 2048 old Shading Units able to execute Int32 or float point shrinked to 6nm.
And that's the throttling FE version even.
so 7600 XT being 203 mm by 1,18 density improvement 7/6 nm = 239 mm is exactly the same thing as 6600 XT. Yeah, lo and behold RDNA3
You cant tile round chips. :p
When combined, thay make the all mighty "not future proof" Doomsday weapon of GPU's.
A few days ago it gave power figures for AD106 based RTX 4060 (230W-240W) that will also fail.
Even by his performance claims you can deduct performance for all configs and if the power draw was what he was saying, i can imagine Jensen in stage at the announcement day detailing performance/W improvements and the audience:"are you f**king kidding me"?
He changed from time to time his wording from TBP, to power limit, to power draw etc but the fact is he was off regarding Ada Lovelace unless Nvidia saw the war and energy crisis and suddenly changed their plans, lol yes sure...
Also why hopefully should the 4070 beat the 7700XT? What a weird statement. Also I doubt the 4070 will easily beat the 3090Ti at all. It could be close and it could win but not by a lot. Let's see how it fairs at 4K with RT on. AMD's perforamnce dropped off at 4K due to the gimped bus widths despite large IC. 4070Ti should handily beat 3090Ti though.
