The new Archos Diamond Tab.

Is the new Archos Diamond Tab a diamond in the rough or just rough? With dual-band Wi-Fi, an octa-core processor and 4G LTE Internet connection on the go, you get quite a lot for the £180 asking price.

The Diamond Tab goes on sale in the UK in October for £180. Global release dates and prices are yet to be confirmed, but a spot of back-of-an-envelope maths shows that price works out at roughly $280 or AU$390.

As well as 4G LTE for faster Web browsing and Internet connection while you're out and about, the Diamond Tab offers dual-band Wi-Fi. So you can connect to the 2.4GHz Wi-Fi that's found almost everywhere, but if you do find yourself a hotspot that offers the less common 5GHz Wi-Fi you can opt for that instead and connect to the Web even faster.

The screen is a 7.9-inch display with a resolution of 2,048x1,536 pixels. That works out at 324 pixels per inch. Those numbers are the same as the iPad Mini with retina display, another 7.9-inch tablet that costs about £60 more.

Under the screen is a beefy eight-core 1.7GHz Mediatek MT8752 processor, backed by an equally meaty 3GB of RAM. There's a microSD card slot and 32GB of storage built in for your movies, music, apps and snaps, but as with all devices some of that space will already be taken up by the tablet's software.

That software is Google's Android operating system, which you may be familiar with from your phone. Android offers a vast catalogue of apps to download from the Google Play online store to your tablet, as well as the usual Google goodies like Gmail and Google Maps. You can customise your home screen with quick links to your favourite apps, and see your latest messages, updates and notifications by swiping down from the top to see the notification centre.

The Diamond Tab runs the last version of the software, Android 5.1 Lollipop, rather than the upcoming 6.0 Marshmallow.

Also on board is a 5-megapixel camera on the back for proper pictures and 720p video, and a lower-resolution 2-megapixel camera on the front for video chat or selfies. The battery is a 4,800mAh job. All this is encased in a body that's 7.8mm thick, weighing around 360 grams (12.7 ounces).

The Diamond Tab joins the new Archos Diamond S smartphone , the flagship phone from the French manufacturer. Both devices will be shown off for the first time next week at IFA, the annual technology trade show where manufacturers gather to show off their wares for the rest of the year and beyond. CNET will be there in force to bring you all the hands-on first impressions, photos and video you need of the coolest gadgets going.
