A couple of sites are claiming that NVIDIA intends to replace the first-generation GeForce GTX 750 Ti with more Maxwell, in the form of the GeForce GTX 950 and/or GTX 950 Ti. The general consensus is that it will run on a cut-down GM206 chip, which is currently found in the GTX 960. I will go light on the rumored specifications because this part of the rumor is single-source, from accounts of a HWBattle page that has been deleted. But for a general ballpark of performance, the GTX 960 has a full GM206 chip while the 950(/Ti) is expected to lose about a quarter of its printed shader units.
The particularly interesting part is the power, though. As we reported, Maxwell was branded as a power-efficient version of the Kepler architecture. This led to a high-end graphics cards that could be powered by the PCIe bus. According to these rumors, the new card will require a single, 8-pin power connector on top of the 75W provided by the bus. This has one of two interesting implications that I can think of.
- The 750 Ti did not sell for existing systems as well as anticipated, or
- The GM206 chip just couldn't hit that power target and they didn't want to make another die
Whichever is true, it will be interesting to see how NVIDIA brands this if/when the card launches. Creating a graphics card for systems without available power rails was a novel concept and it seemed to draw attention. That said, the rumors claim they're not doing it this time… for some reason.
