Haswell provides better performance, while previous Pentium and Celeron chips based on Core architecture have sold well. The Pentium and Celeron chips are stripped-down versions of fourth-generation Core processors, which are used in Ultrabooks and laptops that are more expensive.
Intel is providing a range of chips for laptops at different prices, and the Celeron chips are expected to be used in Chromebooks with Google’s Chrome OS. The company wants to launch Pentium and Celeron chips based on Bay Trail for low-cost desktops and laptops.
There are three dual-core Celeron and three dual-core Pentium processors. The 1.4GHz Celeron 2955U and 1.6GHz Celeron 2980U draw 15 watts of power, while the 2.0GHz Celeron 2950M draws 37 watts of power. The 1.20GHz Pentium 3560Y draws 11.5 watts of power, the 1.7GHz Pentium 3556U draws 15 watts of power, and the 2.3GHz Pentium 3550M draws 37 watts of power.
While the chips have 2MB of cache, they can’t use the same graphics capabilities as the Core processors because of slower and older Intel integrated graphics processors. The new chips lack multithreading and Turbo Boost but you would expect that.
