NVIDIA has enjoyed quite a bit of success the last couple of years thanks in part to its GeForce 6 and 7 Series graphics cards. Like every other company in the world, NVIDIA likes to ride its success as long as possible. In NVIDIA's case, this can be done with product refreshes. The most recent refresh brought us the GeForce 7950 GT, interestingly positioned between the 7900 GT and 7900 GTX.
What's attractive about the GeForce 7950 GT is that it doesn't cost much more than a 7900 GT yet it offers nearly the same performance of a much pricier 7900 GTX. Additionally, the 7950 GT sports 512MB DDR3 clocked at 1.4GHz (effective). The GPU core runs at a speedy 550MHz. Just like the 7900 GT and GTX, the 7950 GT also boasts 8 vertex shaders and 24 pixel shaders.
Today, we have a 7950 GT from Gigabyte in the labs to see just how well the new GeForce 7 Series card can perform. The GV-NX795T512H-RH features reference clock speeds and a Zalman cooler for a little differentiation outside of the typical reference design HSF assembly. Read on to find out more...
