Well, it's only got 128bit DDR3 when the GTX 550 Ti has 192bit GDDR5, which is a huge bandwidth difference (~3x). Since Kepler doesn't have hot clocks for the shaders, they are about half as powerful as Fermi class shaders, so it's probably more like a GTS 450 with half the memory bandwidth. :shadedshu

Interesting this is how the reveal their new GK107? Kind-of non-dramatic! Wonder how this can stack up against the 7750?
It's kind of a part without a cause beyond legacy display adapter or someone needing current feature support. Yeehaw, something moderately faster than what will be in Trinity, and almost certainly similar (in practical use) to whatever comes next year inside CPUs.

As for speed, I would reckon it is similar to 7750 at 800mhz. I would also reckon it is slower than a 7750 at 900mhz. AMD certainly didnt change their products mid-cycle just for kicks.

Math sez something like:

512 @ 1/6 rate special function = 426.66_

426.6_/384 * 800 = 888.88_mhz

with bandwidth difference you get something around 926mhz. Whaddya know, it turbos to 950mhz.

Avg those out and it should be roughly 2% faster...you know, enough to put it ahead in W1z' bar graph. ;)

I have been waiting for this soo much! I was so inspired to make a MiniITX low-profile RIG, like PowerColor. SOLD!

http://www.expreview.com/19768.html About 18% worse on average than the 7750.
But then the same price, I wonder when AIB's will bring 7750 on a half-hight. And why in that review is the GT640 have a 6-pin?

I'm hearing that 640 for Aftermarket should be all Keplers and there are 3 versions...

Odd, to combine the word "unleash" with a mid to low end card. On the plus side, now that "unleash" is associated with mid, value segment, and rebranding shenanigans, then perhaps, finally, we will stop hearing this horrible word/catchphrase.

the GDDR5 version should match the 7750.
But that Galaxy they tested had DDR3 and includes the Dynamic clock and needs the 6-Pin. The card they are suggesting here for $110 price looks more to be a reference DDR3 product. A full "Top Shelve" looks to have 384 Cuda, and knowing the GK104 has 192per SMX, this means a GK107 has two full SMX units, but can there be higher SMX count variants on a GK107 something tells me... No.

This doesn't bode well for mid-range because a GK104 might not scale well with so many SMX disabled? A 660ti would be 6 SMX, a 660 Non-ti working with 5, and a 650 having 4, which is twice what a GK107 has (we just don't know). We aren't yet told just how many SMX the GK107 has on it, but I think it’s a full iteration with 2 SMX and if it is... this is weak.

And to the price PNY web store list it at $130

this is a rebranded GTx560Ti

http://www.aria.co.uk/Products/Comp...R5+PCI-Express+Graphics+Card+?productId=47266

the similarity to these listed specs is not coincidental ,kepler my ass.

no mention of kepler anywhere or the shader clocks is instantly a bit suss, as 384 new kepler shaders arent going to be very impressive at all imho
This new entry-level NVIDIA 28nm Kepler card features dedicated graphics performance from this powerful next-generation GeForce architecture.
Or are you talking about some other article?

??? you think this is so based on cuda cores alone??? :confused:

this is NOT a 560 ti....my well educated guess is that the 560ti will smoke this thing!!!

im betting this will perform exactly the same + or - 10% ,most likely a slight increase. but 384 new shaders doesnt equate to a 640 to me in kepler terms im expecting 784 maybe 588 with high clocks, i could be wrong but they wouldnt be shy with the kepler branding would they, and their is none

toms hardware has a review up on the card and it cant even compeate with a gts 450 let alone a 560 TI......somewhere around the 6670 level
seems i was wrong, but damn i wish i was right ,cos a 560 seems so much better then this its not funny

anyone noticeing the disparity between this and their gk104, it seems to me to prove that most of the 680's awsome gameing performance comes from the quad setup, polymorph and raster outputs and that its shader arrays deffinately arent as strong fermi's was or Amd's are
