Amazon fans its tablets' Fire with refreshes: Fire HDX 8.9, Fire HD 6, and Fire HD 7

Amazon is offering up a refreshed hardware edition of its Kindle HDX 8.9, which is up for pre-order today alongside the Fire HD 6 and Fire HD 7 slates. The refreshed hardware gives the HDX 8.9 some added power to make it stand out in the crowd, and Amazon says that its latest flagship slate will be the first to come with Dolby Atmos with simulated 3D sound for all that multimedia streaming you'll be doing with Amazon Prime Instant Video and Music.

The HDX 8.9 comes with a 2.5 GHz quad-core processor that offers 70 percent faster graphics, a 2560x1600 display (that's 339 ppi) and a 100 percent sRGB pixel arrangement. All this performance still allows the HDX to fire up for 12 hours of usage, according to Amazon. The Kindle Fire HDX 8.9 starts at $379, or can come equipped with AT&T or Verizon LTE starting at $529 with 32GB of storage.

In terms of the smaller slates, those will have smaller 7- and 6-inch displays with a 1280x800 resolution. Audio will come by way of Dolby Digital Plus and both slates will be powered by a quad-core 1.5 GHz processor. They also now come in five bright color options, building on the drab black color choices of old. The HD 6 starts at an amazing $99 while the refreshed HD 7 starts at last year's $139 price point.
