Nvidia has just taken the wraps off the $149 (£115) GTX 750 Ti and $119 (£90) GTX 750 graphics cards based on its new Maxwell architecture. Both cards are available to purchase now.

The company is claiming Maxwell has twice the performance per watt of Kepler, and--in the case of the GTX 750 Ti--performance on par with a GTX 480, but with a power consumption of just 60 watts.

All models of the GTX 750 Ti and GTX 750 will feature two DVI outputs and HDMI, with some third-party manufacturers including Displayport too. Neither card requires a 6-pin power connector.

Core features of the GTX 750 Ti include 640 CUDA cores, a 1020 Mhz base clock, 2GB of 128-bit GDDR5 memory, 2048KB of L2 cache, and a 5.4Gbps memory speed. The GTX 750 features the same base clock, but only 512 CUDA cores, 1GB of 128-bit GDDR5 memory, and a 5.0 Gbps memory speed.

While the GTX 750 Ti is a midrange GPU, early benchmarks have shown excellent performance across a range of games. In GameSpot's own testing the card ran the likes of Tomb Raider and Bioshock Infinite at over 60fps on high settings. It also ran the beta of the new mech-based shooter Titanfall at 58fps at 1080p with 2XAA on, a feat not even accomplished by the Xbox One.

Nvidia also dropped in a little something for power users, announcing the new GTX Titan Black, the follow-up to the extremely powerful and extremely expensive GTX Titan. The GTX Titan Black features the same full implementation of the GK110 Kepler chip as the GTX 780 Ti, and pairing it with 6GB of 384-bit GDDR5 memory and double precision math.

No pricing has been announced for the GTX Titan Black, but expect it to be a lot. The GTX Titan launched at over $1000.
