An Amazon tablet has been spotted in a GFX Benchmark, indicating that recent rumors regarding the next-generation Kindle Fire HD tablets may be accurate.

Speculations have been rife that Amazon's 2013 Kindle Fire lineup will take things to the next level and will feature higher resolutions, more powerful processors and better specs all around.

Italian site Webtrek points to a GFX Benchmark entry for an unnamed Amazon tablet codenamed Apollo/ KFAPWA. According to this entry, the slate in question sports a display with a 2570 x 1600 resolution and runs on a customized operating system based on Android 4.2.2 Jelly Bean.

The tablet apparently packs the latest Qualcomm Snapdragon 800 chipset paired with Adreno 330 graphics. The listing does not mention the device's screen size. It may be an 8.9-inch slate, but there's no way to tell for sure at this point.

Back at the end of July, BGR reported that the next-generation Kindle Fire HD lineup will boast the Snapdragon 800 processor, which is generally suitable for top-tier devices. Such a chipset would make it difficult for Amazon to keep the costs down, but the company may have a trick up its sleeve.

The same report claimed that the next 7-inch Kindle Fire HD will sport a high-resolution 1920 x 1200-pixel display, a new design and 2GB of RAM to go with the Snapdragon 800 and Adreno 330 GPU. The slate would also include a front-facing camera, Wi-Fi, cellular connectivity, 16/32/64GB storage options and Android 4.2.2 underneath Amazon's heavy customizations.

The next 8.9-inch Kindle Fire HD will reportedly pack an 8-megapixel rear camera in addition to the new specs found on the 7-inch model, according to the same report from BGR in late July.

The publication claimed at the time that Amazon plans to unleash its new line of tablets in the fall, potentially in late September. While those rumored specs remained unconfirmed, the new GFX Benchmark entry seems to fall in line with previous reports.

Until Amazon makes it official, however, it is advisable to take all rumors, leaks and speculations with a grain of salt. If the late September timeframe proves to be accurate, the new Kindle Fire HD lineup should become official soon enough.
