NVIDIA is planning on launching two Maxwell-based cards next month. These cards will be the GeForce GTX 750 Ti and the GeForce GTX 750. It looks like the first GeForce GTX 750 has been listed and the listing gives us some details on the card.
The card was listed by Chinese retailer TMall. The listing includes pictures, specifications, and some features of the card. The GM107 GPU which this card is based off would feature 768 CUDA cores, but the number of ROPs and texture units has not yet been confirmed. The card will be clocked at 1020 MHz with the memory at 5 GHz (effective).
The card will only have 1 GB of memory that will run across a 128-bit interface. The Ti version of the card will have 2 GB of memory. Both cards are expected to be released on February 18th.
