Sweclockers reports NVIDIA GeForce GTX 750 Ti graphics card set for launch in February is to be accompanied by GTX 750. Regular GTX 750 (non-Ti) version would be a lower class model with slightly cut down specifications.
Based on Maxwell architecture, GTX 750 has no auxiliary power connectors and draws power only from PCI Express slot. This means card would have power consumption of under 75W. It's said that the card would be around 25% faster than its predecessors, although it's not yet known which current card it's going to replace. GTX 650 Ti is quite possible as GTX 750 Ti is supposed to replace GTX 650 Ti Boost. Specifications of upcoming cards are not known, but Sweclockers reports both cards would have 2GB of GDDR5 memory. NVIDIA's AIB partners are free to use their own custom designs for both cards.
