Details on Nvidia Kepler GK104-based GTX 670 Ti Surface
When something goes wrong during the manufacturing process, what are manufacturers to do? Do what many other have done, you turn the part into a new item with the defective part disabled!
The next two SKUs based on the GK104 Kepler look to be set to release in May under the names GTX 670 and GTX 670 Ti. According to German publication 3DCenter.org, these GK104s will take the same route of the GF100: GK104 on the new cards will have one fewer Streaming Multiprocessors (SMX). These are basically GTX 680s that didn't make the cut during manufacturing with one of the SMX units disabled. The SMX units holds 192 CUDA cores, so with seven out of eight SMX units enabled, you end up with a 1344 CUDA core count. This allows Nvidia to salvage the graphics card and provide end-users with a card a tier or two down the performance charts.
Rumored Specifications for the GeForce GTX 670 Ti:
- 4 Graphics Processing Clusters (GPC)
- 7 SMX Units (192 CUDA cores per units)
- 1344 CUDA Cores
- 112 Texture Units (TU)
- 32 Raster Units (ROP)
- 256-bit Memory Controller
- 2 GB GDDR5 Memory
- Estimated base core clock of 900 MHz (boost clock not known)
- Estimated 1250 MHz (5.00 GHz GDDR5 effective) memory clock, with around 160 GB/s memory bandwidth
- Estimated price $349-399 dollars
The GTX 670 Ti is expected to see a 20 percent drop in performance when compared to the GTX 680. With its estimated performance and price point, the GTX 670 Ti is set to do battle against AMD's Radeon HD 7950 and previous generation GTX 580.

general lee I don't get it why news sites keep posting stuff that's clearly labeled as forum speculation.Reply -
-Jackson hellfire24for $350,not bad!It's only an estimation, in reality, it's most likely going to be more than the estimated price.Reply

tomfreak so I am guessing GTX670 non ti will have another SMX disabled? @ 1024 cuda cores? wishing GTX670 ti @ 350, 670 @ 299, then its time to release a 2 GPC GK106.Reply -
Pherule esrevermainstream gpus yet?Haven't you heard the stories? These ARE the mainstream gpu's. (Although factually, calling them gpu's is incorrect) Nvidia hasn't released their high end yet because the 7000 cards can't compete... for now.Reply -
Memnarchon hellfire24for $350,not bad!Not bad at all. Assuming (by comparing the number of the cores from 680) that it will have performance between 7970 and 7950!!!!Reply

If the 2nd will become true too it will have 1152 cores 6/8 and not 1024.
If they will price GK104 7/8 SMX at $349, then there is a possibility for GK104 6/8 SMX to be lower than $300 (something like $249 up to $299). If this happens, this should become best seller...

stingstang PheruleHaven't you heard the stories? These ARE the mainstream gpu's. (Although factually, calling them gpu's is incorrect) Nvidia hasn't released their high end yet because the 7000 cards can't compete... for now.Yea, and i'm sure they haven't released their low-end yet for the same reason...Reply -
ojas general leeI don't get it why news sites keep posting stuff that's clearly labeled as forum speculation.No, this is most likely not speculation. When Kepler went live, the press was given access to their corporate ftp server for the launch goodies (pics, white-papers, reviewers guides, etc).Reply
Anyway, you know files have tags, right? So at least two of the supposed GTX 680 images had 670 Ti as a tag. I mean, i have the files with me, so this is first hand info ;)
Anyway, this is believable, because they do the same with the 560 Ti 448 Core edition. -

But then what they meant was that the dual GPU one is going to be "high end".Reply
