The Motorola XOOM tablet is fast turning out to be a tweakers' dream platform as one of them, a member of the XDA-developers forum, has managed to overclock the XOOM system on chip by 50 per cent to a whopping 1.5GHz.
The feat was managed by coolbho3000 and as expected, needed the XOOM's bootloader to be unlocked and rooted quite easily (tutorials can be found here and here); crucially, Motorola has confirmed that it was perfectly legal to customise the tablet's bootloader, something the competition still has to catch up with.
The overclocked Motorola XOOM scored a whopping score of 3105 on the Quadrant benchmark, more than twice the score of the Nexus One or the Motorola Droid, both of which have single core Cortex A8-based SoCs.
We're not sure how this will affect the thermal properties of the tablet; the Tegra 250 uses a 40nm manufacturing process from TSMC and comes with an 8-core Geforce Ultra Low Power GPU clocked at 333MHz.
Overclocking the core should also, in theory, have an impact on the graphics performance and power dissipation plus it may have a negative impact on the battery life. Below is a video of the overclocking process as presented by coolbho3000.
The flip side is that users will be able to cut down on speed (or even the number of running cores) to increase battery life without skimping too much on performance.
