NVIDIA today announced two new mainstream GPUs based a variant of the company's Kepler architecture. Which according to NVIDIA offers consumers some of the world's fastest and most efficient high performance computing (HPC) GPUs. NVIDIA promises it will deliver impressive gains in terms of power and performance for desktops and laptops alike.

NVIDIA has already launched several GPUs in the GeForce 600 Series which are all based on the Kepler designed chips. Today's announcement fills the gap between the budget friendly GT 600 series and the enthusiast level GTX 660 Ti and NVIDIA's high-end cards the GTX 670, GTX 680, GTX 690.

Looking at the early benchmarks and reviews its easy to see these cards perform about as well as to be expected. That is to say there aren't any major surprises one way or the other. They were built to fill a gap in NVIDIA's line-up and compete with some of the lower cost options from AMD and they seem to do that fairly well. This is by no means a bad thing, it simply means that this is just an everyday product launch.
