NVIDIA announced the GeForce GTX 750 series graphics cards, including the GeForce GTX 750 Ti, and the GTX 750. Based on the 28 nm "GM107" silicon, the two are the first to be based on NVIDIA's next-generation "Maxwell" GPU architecture, which feature an upgraded streaming multiprocessor design that promises performance-per-Watt improvements, which can be traded for higher performance over the previous generation. The GTX 750 Ti features 640 CUDA cores, 48 TMUs, 16 ROPs, and a 128-bit wide GDDR5 memory interface, holding 2 GB of memory. The GTX 750, on the other hand, features 512 CUDA cores, 40 TMUs, 16 ROPs, and just 1 GB of memory, across a 128-bit interface. The GTX 750 Ti is priced around $150, and the GTX 750 around $120.
