In fact we didn't expect to see them until September and a few more than just two. These appear to be the advance guard for a larger assault on laptops before Intel kills off the Celeron brand.
First up there is the dual-core Celeron 857 which runs at a clock speed of 1.2GHz, has 2MB of RAM and is priced at $134 for 1,000 units.
Then there is the single-core Celeron 787 which has a clock speed of 1.3GHz, 1.5MB of RAM and is priced at $107. Both processors have on-chip graphics and draw 17 watts of power. That's according to CIO.
Generally at those speeds they are hardly going to set the world on fire. They are being targeted at very low end basic laptops which find word processing and internet surfing about the best they can manage.
Celeron does not include Turbo Boost, in which cores can be shut down to save power or cranked up to boost processor performance. They lack Quick Sync which converts high-definition video into a format suitable for smartphones and tablets.
They will be competing with AMD's E-series and C-series chips and so far there are no PC makers who have put their hands up to say they will use them.
The Celeron chips lack some graphics, power-saving and speed-enhancement features found on the latest Core processors, which are also based on Sandy Bridge.
