GK104 takes a step down
While the graphics power found in the new GeForce GTX 690, the GeForce GTX 680 and even the Radeon HD 7970 are incredibly impressive, if we are really honest with ourselves the real meat of the GPU market buys options much lower than $999. Today's not-so-well-kept-secret release of the GeForce GTX 670 attempts to bring the price to entry of the NVIDIA Kepler architecture down to a more attainable level while also resetting the performance per dollar metrics of the GPU world once again.
The GeForce GTX 670 is in fact a very close cousin to the GeForce GTX 680 with only a single SMX unit disabled and a more compelling $399 price tag.
The GTX 670 GPU - Nearly as fast as the GTX 680
The secret is out - GK104 finds its way onto a third graphics card in just two months - but in this iteration the hardware has been reduced slightly.
The GTX 670 block diagram we hacked together above is really just a GTX 680 diagram with a single SMX unit disabled. While the GTX 680 sported a total of 1536 CUDA cores broken up into eight 192 core SMX units, the new GTX 670 will include 1344 cores. This will also drop the texture units to 112 (from 128 on the GTX 680) though the ROP count stays at 32 thanks to the continued use of a 256-bit memory interface.

Earlier this week we reported on a rumored MSI GTX 670 graphics card with a “DispalyPort” that was coming out soon. A new photo of the MSI card is below along with the box (though the typo is covered up by the card). Swelclockers has now gotten their hands on even more photos of the alleged GPU–this time from manufacturer Asia Colorful. The two rumored cards are said to be based on the NVIDIA reference design, and supporting the rumors, both cards do look very similar in design.
The alleged MSI GTX 670 GPU
The cards that appear to be Kepler based GTX 670s have a black PCB that extends about 3/4ths of the length of the heatsink and fan cooler. Except for a bit of overlap, the heatsink covers the PCB and the fan is located in the part of the card that hangs past the edge of the PCB. It also looks like they have moved the PCI-E power connectors to the outside edge of the card–a different rumored GTX 670 had the PCI-E power on the back edge of the card.

As far as specifications, the cards support PCI-E 3.0, two DVI outputs, an HDMI and what looks like a DisplayPort output. Beyond that, the card is said to be based on a scaled down version of NVIDIA’s Kepler architecture based GTX 680 GPU. For the GTX 670, NVIDIA has allegedly disabled 192 CUDA cores for a total of 1344. They have also reduced the base GPU core clockspeed from 1,006MHz on the GTX 680 to 900MHz. Although the card still uses the same 256-bit memory interface, the GTX 670 has a reduced memory (GDDR5) clockspeed of 5GHz versus 6GHz on the GTX 680. Because of the scaled back nature of the card, it has a lower TDP of approximately 150W.
Because they have been spotted in retailer’s hands, the GTX 670 is likely very close to release. Rumors are now suggesting that the card will be sold for somewhere between $349 and $379 USD.
Also on the Kepler front, is this cool looking single slot Kepler-class GPU that may or may not be a custom designed GTX 670. What Kepler rumors have you heard, and are you looking forward to the cheaper GTX 600 series cards?
It seems like MSI has some cheaper Kepler based NVIDIA graphics cards coming soon if this photo from Malaysian retailer Cycom turns out to be legitimate. Spotted by Lowyat user Chapree, the photo appears to be an MSI GTX 670 graphics card. Further, the card appeared on the company’s website at a price of 1399 Malaysian ringgits which translates to just under $462 USD.
Interestingly, the box contains a typo for Displayport in the form of “DispalyPort.” While that may indicate a fake card, it doesn’t totally rule it out either. The NVIDIA GTX 680 is the only available Kepler card (if you can find one to buy that is!), and many users are clamoring for some cheaper options. Here’s hoping they are coming sooner rather than later!
