The Kindle Fire HD 7 is just a mild revamp, with a 7-inch 1280x800 screen, 1GB of RAM and a dual-core OMAP4 4470 SoC. It is priced at just $139 for the 8GB version and it is anything but impressive.
Moving on to the really new stuff, the Kindle Fire HDX 7 sports a 7-inch 1920x1200 display with 332ppi. The brains behind the operation come from Qualcomm, in the form of the Snapdragon 800 SoC with Adreno 330 graphics. The CPU is clocked at 2.2GHz, while the GPU can hit 450MHz. It has 2GB of RAM. Unlike the old HD 7, it has GPS and a compass, along with a front facing camera – but no rear camera.
The price stands at $229 for the 16GB version, while the 32GB unit costs $269 and the 64GB model goes for $309. LTE support adds a whopping $100 to the list price.
The Kindle Fire HDX 8.9 is a beast. Like the HDX 7, it too is powered by a Qualcomm 8074 chip and ships with 2GB of RAM. However, it also boasts a razor sharp 8.9-inch screen in 2560x1600, along with an 8-megapixel rear camera. The downside? It’s not very cheap.
Prices start at $379 for the 16GB model and going for LTE will add another $100. The 32GB and 64GB versions sans LTE cost $429 and $479.
