Fermi through Maxwell: 5 Generations of GeForce Graphics Compared

When new GPUs arrive we usually compare them to their predecessor but rarely go back more than one generation. Today we'll be testing six cards covering three key Nvidia architectures: Fermi (the GTX 480 and GTX 580), Kepler (theGTX 680 and GTX 780) and Maxwell (the GTX 980). Many of you who haven't upgraded GPUs in over a year may be pleased to see how performance scales and what to expect in modern games.

GeForce GTX 650 Ti Review: Kepler Hits $150

It's been over six months since Nvidia launched its Kepler architecture and we've finally seen the GTX 600 series enter more affordable price brackets, delivering a greater value every step of the way.

Having attacked the mid-range and upper-end markets, Nvidia has its sights set on the sub-$200 range, unleashing its GTX 650 Ti. At $150, the new arrival is roughly 34% cheaper than last month's GTX 660 and about 7% pricier than the Radeon HD 7770, which fetches around $140 depending on features and rebates. Here comes our full review.

Kepler Strikes Again: Gainward GeForce GTX 670 Review

After months of talking up its latest architecture, Nvidia reclaimed the single-GPU performance crown with its GeForce GTX 680, which outpaced the Radeon HD 7970 by about 7% in our tests. Kepler's arrival forced AMD to slash prices across its Southern Islands lineup.

The HD 7950 took a $60 cut to $399, making it one of the most tempting 7000 series cards because it has no equal -- or had no equal, we should say. Continuing Kepler's rollout, Nvidia has unveiled the GTX 670, which is priced against the HD 7950 at $399. Despite being $100 cheaper than the GTX 680, the GTX 670 doesn't appear to be much slower on paper, and that could spell disaster for AMD.
