With major players unleashing a slew of budget-friendly devices to capture consumer interest, the tablet space is becoming increasingly competitive. Both Google and Amazon are established names in the 7-inch entry-level tablet market and command a decent share with their Nexus 7 and Kindle Fire offerings.

Amazon launched its original Kindle Fire in 2011, which went on to dominate the market as the top budget tablet option, until the Nexus 7 came along. The Nexus 7 was released in July 2012 and has gone on to become one of the best-selling tablets on the market since its release. The 16GB version was sold out within weeks due to high demand. Analysts predict that the Asus-built Nexus 7's sales figures will touch the 8 million mark by year end.

Now, Amazon has decided to up the ante and has revealed a 7-inch Kindle Fire HD challenger. Amazon claims that it is the "world's first tablet with dual antenna, dual-band Wi-Fi for ultra-fast downloads and HD streaming."

Here's a look at how the two tablets stack up against each other.

Display

Both devices have a 7-inch capacitive display with multitouch. With the new Kindle Fire HD, Amazon has improved on its screen resolution from 600 x 1024 to 1,280 x 800, the same as the Nexus 7's resolution. Both tablets have a 216 ppi. However, a substantial bezel surrounds the Kindle Fire HD's screen, making the device a bit wider than the Nexus 7. dditionally, Amazon also claims that the panel used in the Kindle Fire HD contains a polarizing filter to reduce glare.

Size and Weight

The Nexus 7 measures 7.82 inches x 4.72 inches, compared to the Kindle fire HD's 7.6 inches x 5.4 inches. At .75 pounds, the Nexus 7 is lighter than the Amazon offering, which weighs .87 pounds. Not much difference exists in the thickness of both devices; the Nexus 7 and Kindle Fire HD are .41 inches and .40 inches thick, respectively.

Processor and Operating System

A 1.3GHz quad-core Nvidia Tegra 3 processor with 1GB of Ram powers the Nexus 7. On the other hand, the Kindle Fire HD features a 1.2GHz dual-core OMAP4460 processor with "Imagination PowerVR 3D graphics core for fast and fluid performance" and 1GB of RAM. The dual-core Kindle Fire HD processor is considerably slower than Nexus's quad-core one. The Nexus 7 comes pre-loaded with the latest Android 4.1 Jelly Bean. By contrast, the Kindle Fire HD will come with Android 4.0 Ice Cream Sandwich out of the box.

The Nexus 7 has Google Play, which stores movies, music, and books in the Google Play cloud. Both tablets pack in Wi-Fi and Bluetooth support. However, the Nexus goes one up on the Fire with its GPS and NFC abilities. On the other hand, when it comes to data connection, the Kindle Fire HD has both Micro USB and HDMI. By contrast, the Nexus 7 only offers Micro USB support.
