NVIDIA GeForce RTX 3070 and RTX 3070 Ti Rumored Specifications Appear
NVIDIA is slowly preparing to launch its next-generation Ampere graphics cards for consumers after we got the A100 GPU for data-centric applications. The Ampere lineup is getting more and more leaks and speculations every day, so we can assume that the launch is near. In the most recent round of rumors, we have some new information about the GPU SKU and memory of the upcoming GeForce RTX 3070 and RTX 3070 Ti. Thanks to Twitter user kopite7kimi, who had multiple confirmed speculations in the past, we have information that GeForce RTX 3070 and RTX 3070 Ti use a GA104 GPU SKU, paired with GDDR6 memory. The cath is that the Ti version of GPU will feature a new GDDR6X memory, which has a higher speed and can reportedly go up to 21 Gbps.
The regular RTX 3070 is supposed to have 2944 CUDA cores on GA104-400 GPU die, while its bigger brother RTX 3070 Ti is designed with 3072 CUDA cores on GA104-300 die. Paired with new technologies that Ampere architecture brings, with a new GDDR6X memory, the GPUs are set to be very good performers. It is estimated that both of the cards would reach a memory bandwidth of 512 GB/s. So far that is all we have. NVIDIA is reportedly in Design Validation Test (DVT) phase with these cards and is preparing for mass production in August. Following those events is the official launch which should happen before the end of this year, with some speculations indicating that it is in September.

2.944/3072 shaders x 2 Ghz x 2 instructions per clock = 11.78/ 12.29 FP32 (float) performance... (RTX 2080TI FP32 = 13.45)
Either this thing can boost clocks higher than 2Ghz (+2.2Ghz), has +10% IPC gain, or we're f...ed.
GTX 670 was 6 % slower than GTX 590 ....... 40->28nm
GTX 770 was 51 % slower than GTX 690 ($1K GPU in 2012!) .......-> 28nm both
GTX 970 was 3% slower than GTX 780 TI ...... 28nm both
GTX 1070 was 12% faster than GTX 980TI 28nm .... 28nm ->14nm
RTX 2070 was 10% slower than 1080TI ...... 14->12 nm
RTX 3070 ? 2080TI ....... 12->10 nm or 12nm -> 7nm?
Are we in for another Turing moment? If my calculations stand, we might get 2080S level of performance for 500 bucks when Xbox X costs the same while offering similar TFlops horsepower.
Something's not right here. 3070(TI) being slower than 2080TI would just not be a worthy upgrade considering new consoles performance. Or Nvidia just don't care about PC gamers migrating to consoles?
Also, starting out with an xx70 Ti SKU in the lineup speaks to the price ladder extending higher yet again - adding rungs to the middle at launch isn't likely to push lower tier prices down, just push higher ones up. Hooray!
Also, mass production in August either means mass production of the die in August, which means 4-6 months before these hit the streets, or mass production of partner cards in August, which as noted above means some early cards might arrive 1-2 months after, no time to build up stocks, so availability will be bad for several more months.
Even with GDDR5X there was something about it months before from Micron. You would thing there would be some proof of it's existance?
And would this be Nvidia exclusive with AMD using "regular" GDDR6?
Or does Nvidia think that AMD will use HBM2 and thus needs to have this special memory to compete?
I mean hey - if it turn out to be accurate - great. But i still have my reservations.
I bet the price will go up though...
But wait&see and big grains of salt seem to apply to most of the latest rumors...
FTFY. :p
Here I don't even understand the numbers. 21Gbs is what kind of speed, sounds more like bandwidth? 21GHz?
If it's 21GHz, why the final bandwidth is so low, only 512GB/s?

As you can see every time NGreedia went to double node density, we got around previous generation's xx80 TI level of performance. Why would anyone even consider buying 3070 if it offers 2080(S) level of performance for 500 bucks? Nvidia's 3070 GPU has to beat XBox X by a decent margin or many PC gamers will have hard time justifying the purchase and might skip Ampere or even decide to buy new console instead. For example, I own 3.5 yo 1080TI and I see no reason in upgrading to Ampere if it doesn't offer 2080TI level of performance for 500 bucks so Nvidia wouldn't see my money for another 2-3 years if performance isn't there. I don't know if that's in their best business interest.

$1499 for lowest end 3080Ti would I dare say?
please... PLEASE GPU makers, don't stuff us with more than 12GB of VRAM.................
