The Cube U30GT is one of the first Android tablets to ship with a Rockchip RK3188 quad-core processor, which makes it one of the fastest Chinese tablets available to date.

It’s also not a bad looking tablet, and it has a high resolution 10.1 inch, 1920 x 1200 pixel display. Geekbuying sells the Cube U30GT2 for $266, and the company sent me a demo unit to check out.

I’ll have a full review of this tablet soon, but I wanted to share some initial thoughts and benchmark results.

As expected, this tablet is fast. The Rockchip RK3188 processor is a quad-core ARM Cortex-A9 chip which performs at least as well in most performance tests as Samsung’s Exynos 4412 quad-core chip and better than NVIDIA’s Tegra 3.

In the chart above, note that the Ramos W42 tablet has an Exynos 4412 chip, while the Asus MeMO Pad ME301T and Google Nexus 7 both have NVIDIA Tegra 3 processors.

The Cube U30GT2 outperforms them all in each of the three benchmark tests I ran, including tests which look at CPU and graphics performance and data read and write speeds.

These tests aren’t always indicative of real world performance, but during the few hours I’ve had my hands on the Cube U30GT2, I’ve found it to be fast and responsive when surfing the web, watching videos, and running other apps.

But I did run into one problem with the tablet so far: WiFi reception is decent, but not stellar. When sitting in my living room near my wireless router, I was able to surf the web, stream internet video, and download apps effortlessly.

Update: There’s a 1.03 firmware update that seems to help improve WiFi range. I can now use the tablet in my office… although occasionally I lose the connection and have to reboot to get it back. 

In my home office on the third floor of our house I wasn’t able to even login to my Google account. The tablet said it was connected to the internet, but I couldn’t get online using the web browser or any other apps.

The Cube U30GT2 features 2GB of RAM, 32GB of built-in storage, micro USB and micro HDMI ports, and a microSD card slot. It has a 2MP camera on the front and a 5MP camera on the back with auto-focus and an LED flash.

The tablet runs Android 4.1 Jelly Bean software.

  1. It is suggested that you remove the silver strip around the tablet, this will increase the wifi signal…. I however am having a huge problem with the bluetooth signal, can’t even get a decent signal at a 1m range…otherwise though a very impressive tablet

  2. Sounds very nice – except no GPS! That’s a deal-breaker for me. If they come out with one with GPS (without losing any of the other hardware) and it tests well in the real world, I would strongly consider buying one.

  3. The 1.03 firmware update has improved WiFi range only a little. Up to now I really can’t use the browser und I often lose the connection and have to reboot
    to get it back.

  4. Hi. I have the same wifi problem with my Cube U9GT5. Have you find a solution?

    1. 20k when the Resolution is 1024×768 is no so hard to achieve ..Onda will probabaly get Half with 1920×1200 .

  5. Brad would you mind putting it through its paces with some specific games, namely Real Racing 3 and The Simpsons Tapped Out? I’d like to know how they perform and whether they need to be sideloaded or not. Thanks in advance!

    1. FNF ifive has a 7 inch version, which is highly rated. little brother of the 8.9 in ifive x2 i have.

      1. I really appreciate the tip, but I got a 2013 Nexus 7 a couple of months ago. (Thanks, Brad, for the great review!!). I couldn’t resist the great specs plus the fact that it’s made by Asus, my favorite manufacturer, plus I got 15% back in Rakuten “Super Points” (not very super at 1 cent apiece, but if you get 4,500 of them, they add up 😉

  6. Cube is the best price/performance, as good as it is rebranded by several brands to provide tech support at each country. Benq and FNAC are 2 I know here in Spain, but there are more

  7. How is the build quality overall, and for the screen?
    Gorilla Glass quality and good colors on the screen?
