Intel reportedly told some of its partners that the upcoming dual-core Sandy Bridge notebook processor should be about 20 percent faster than Arrandale, according to a report by FUD Zilla.
These are still projections despite the fact that Intel has had Sandy Bridge since last IDF that took place in late September 2009 and that prototypes of this new 32nm architecture are out.
The „around 20 percent“ projections are made when Intel compared the top range Sandy Bridge (SNB) and top of the bin dual core Arrandale. This doesn’t necessarily have to mean that Intel compared two processors at the same clock. We do know that Sandy Bridge has new Intel AVX instructions but we doubt that they can pull some 20 percent performance increase clock to clock.
