Benchmark results of an Intel dual-core Silvermont processor have leaked. This future x86-chip is developed for use in smartphones and tablets. Compared to its ARM counterpart, the x86 architecture isn't exactly known for its efficiency. With the new Silvermont, Intel aims to do it differently though. The use of a different architecture doesn't matter for the operating system; Android works (almost seamlessly) with both.
In AnTuTu, the 'Bay Trail-T' SoC, with its two 1.1 GHz Silvermont cores, scores 43,416 points. This score is significantly higher than most devices with a quad-core Qualcomm Snapdragon 800 processors, which score around 25,000 to 30,000 points. Slides from Intel reveal that the Silvermont chip is far more efficient than its predecessors, and therefore not as limited by the maximum power consumption of a smartphone. As such, Intel claims that an efficient dual-core can be faster than a relatively inefficient quad-core chip.
Compared to earlier Atom processors (Medfield/Clover Field), Bay Trail-T is a leap ahead. Intel states that its up to three times as fast, while simultaneously dropping the power consumption significantly. In final products, the clock frequencies of the new 22 nm Silvermont processors can reach 2.1 GHz, granting the chips even more performance.
