Intel Atom Z2460 Processor : A Potent Rival For ARM?

Intel has finally announced its first Medfield-based product, the Atom Z2460, a single core "Penwell" system on chip that combines a processor clocked at 1.6GHz with a PowerVR SGX540 GPU clocked at 400MHz.

The Z-prefix means that the Z2460 is more closely related to the Lincroft range - which was launched back in May 2010 - with the Z600 clocked at 1.5GHz with a PowerVR SGX535 GPU hitting 400MHz; both have 512KB L2 cache as well.

But while the specs of the Z600 and the Z2460 are on paper fairly similar, in reality, there is a considerable difference.

Moorestown remains a two chip solution while Medfield is a single chip solution. Intel has significantly optimised the Z2460 to sip power - through its own proprietary Smart Idle Technology - while delivering higher performance for smartphones using features such as Burst Performance Technology and Hyper Threading.

Anand of AnandTech provided a detailed analysis of what to expect performance-wise from the Z2460.

On the popular SunSpider Javascript Benchmark, the Medfield reference platform was almost 66 per cent faster than the Samsung Galaxy S II, while it was more than twice as fast as the same phone on BrowserMark.

What's more, it was competitive with both the iPhone 4S and the Samsung Galaxy S2, winning two out of four comparisons.
