NVIDIA is continuing the infuriating practice (though they aren’t alone in doing so) of re-branding older graphics cards into the following generation to present “new” cards (or to confuse consumers and tech journalists to no end, though I suspect that’s just a side benefit). Specifically, they are taking two lower tier desktop OEM cards and rebranding them as 600 series "Kepler" cards. The NVIDIA GT 520 and GT 510 will be renamed the NVIDIA GT 620 and GT 605 respectively. Even more confusing is that the “new” cards will have less hardware, and the only addition is the support for the OpenGL 4.2 standard (versus 4.1 on the 520 and 510).  Other than that, they are two Fermi based cards in Kepler clothing.

The NVIDIA GT 620 replaces the GT 520 and features half of the graphics memory as the 500 series card, meaning that users will get 512 MB or 1 GB on the 620 instead of the 1 GB / 2 GB options of the GT 520. The card still features VGA, DVI, and HDMI video outputs. The remaining specifications can be seen in the chart below. Despite halving the memory, the new card has a very slightly higher TDP at 30 watts versus the rated 29 watts of the GT 520.

On the other hand, the NVIDIA GT 605 is the new version of the GT 510. The 600 series part also halves the amount of memory of the GT 510 counterpart with 512 MB and 1 GB versions compared to 1 GB and 2 GB versions of the GT 510. The GT 605 also has VGA, DVI, and HDMI ports. It is rated at a TDP of 25 watts like the GT 510.

According to Tom’s, the “new” cards are still Fermi based despite the new implied Kepler generation naming scheme. Granted, these are OEM cards but it still is a bit dishonest to rebrand them, especially in the case of the GT 620 where it is the same rank but with the Kepler generation digit at the beginning. There have been some comments around the Internet that the two new rebranded cards were brought into play to allow OEMs to sell PCs with new 600 series discrete graphics. At this level, it really doesn’t matter per se as they will still do HTPC and desktop graphics well enough and are not going to be purchased by customers directly, but it’s still annoying (heh). What do you guys think about the graphics card rebranding in general, whether it’s on the desktop or mobile market?
