Sony’s still playing coy with its latest high-end phone reveal before CES, but at least one person has managed to lay hands on it. ITProPortal‘s tipster didn’t stop there: they’ve managed to benchmark the Sony Ericsson XPERIA Arc HD, also known as the Nozomi. With the latest Qualcomm 1.5Ghz dual-core processor residing inside, it’s got a lot of expectations to live up to. But if this early hands-on is anything to go by, all is not well in the land of XPERIA.

The new processor coupled with a full gigabyte of RAM managed to score just 2219 in a Quadrant benchmark. For reference, that’s about as fast as a 1.0Ghz dual-core phone from mid-2011, and much less than we’d hope for from a brand new flagship device. According to the source, only one of the two processor cores is active, which would account for the relatively poor performance – perhaps Sony just needs to do some last-minute software tweaking to take advantage of that shiny new hardware.

Elsewhere underneath the phone’s metaphorical hood, you get a a whopping 12 megapixel camera (30% denser than the majority of high-end Android phones available today) with an unfortunately sparse 8GB of internal memory to store all those photos. To compound photographer frustration, there’s no MicroSD card slot to be found. Of course, this is all unofficial and could be non-final hardware – the software certainly isn’t finished in any case. We’ll probably see an official unveiling at CES 2012 next week.
