They do all that while using the same amount of juice as their "Cedar Trail" predecessors. Most chips have higher clock speeds than N2805, N2810 and N2910 SKUs and come with Burst Performance technology. They can operate at a higher maximum operating temperature which makes them easier to cool. Finally, in addition to 4 N28xx/N29xx Celerons Intel also released Pentium N2920.
Then there are new dual-core Bay Trail-M microprocessors like the Celeron N2806, N2815 and N2820 which can operate at frequencies from 1.6 GHz to 2.13 GHz, when going downhill had the wind is behind them. They also have the maximum burst speed ranging from 2 GHz to 2.39 GHz. The processors come with 1 MB L2 cache, Ivy Bridge graphics clocked at 311 MHz and up to 756 MHz, and support for DDR3L-1066 memory. The N2806 has 4.5 Watt TDP while the N2815 and N2820 have 7.5 Watt TDP. All of the Celeron N28xx processors are priced at $132.
Two new quad-core microprocessors are Celeron N2920 and Pentium N3520. The CPUs have 2 MB L2 cache, and run at 1.86 GHz and 2.17 GHz respectively, with burst frequencies reaching 2 GHz and 2.42 GHz. Both parts integrate Ivy Bridge graphics, that can be clocked as high as 854 MHz. The Celeron can deal with DDR3L-1066 memory, and the Pentium supports 1333 MHz memory data rate. They fit into 7.5 Watt power envelope. The official prices of Celeron N2920 and Pentium N3520 are $132 and $180.
