Asus has unveiled a new version of the GeForce GTX 950 that reduces the power consumption of the card from 90W to 75W, which allows it to run purely from motherboard power and without any 6-pin PCIe power connectors.
Even though this new GTX 950 has a 15W lower TDP than the standard reference card, it appears to include the same GM206 GPU with near-identical clock speeds. As noted by AnandTech, this should mean that the 75W GTX 950 will perform around the same level as the existing 90W variant.
The Asus GTX950-2G, as it's known, features core clock speeds of 1026 MHz with a boost clock of 1190 MHz: just 2 MHz faster than the reference GTX 950 clocks. There is also an OC mode that pushes the base and boost clocks up to 1051 and 1228 MHz respectively, providing a small improvement in performance, although the low TDP may limit further overclocking.
Aside from the minor modification in clock speeds, Asus' new GTX 950 provides a similar feature set. There's 768 CUDA cores with 48 texture units and 32 ROPs, and 2 GB of GDDR5 frame buffer at 6.6 Gbps. The cooling solution uses two fans and an aluminium heatsink, and you're getting DisplayPort, HDMI 2.0, and DVI connectors on the I/O shield.
The GTX950-2G hasn't appeared in retail channels yet, so there's no word on how much the card will cost. However, other GTX 950s currently sell for around $150-170, so we expect the 75W variant will also fall in this price range.
