Intel marked the start of July with the introduction of a new ultra-low voltage entry-level processor from the Celeron line which is based on the Sandy Bridge architecture and targets cheap ultra-portable mobile computers.
The new chip is called the Celeron M 857 and is designed to replace the Celeron M 847 that started selling just a little more than two weeks ago.
Both of these processors are ultra-low voltage (ULV) parts, which means that their estimated thermal design power is rated at 17W, but the M 857 comes clocked 100MHz higher than its predecessor.
This means that its two Sandy Bridge processing cores now operate at 1.2GHz, while the maximum Turbo frequency of the integrated GPU was raised from 800MHz, in the 847, to 1GHz.
However, the rest of the specifications are identical and both CPUs pack 2MB of Level 3 cache memory and a dual-channel memory controller which supports DDR3 speeds up to 1333MHz.
The on-chip graphics unit includes only the most basic features (lacks even ClearVideo support), and its base frequency is set at 350MHz.
As it’s the case with all the other Sandy Bridge-based Celeron processors launched by Intel, the 857 also lacks support for some of the more advanced technologies found inside higher-performing second-generation Core processors like Turbo Boost or HyperThreading.
As far as pricing is concerned, the Celeron M 857 carries the same $134 price tag as the 487 it displaces.
Outside of the Celeron M857, Intel is also expected to release the ultra-low voltage Celeron 787 CPU, which includes a single processing core clocked at 1.3GHz accompanied by 1MB of Level 3 cache memory.
No firm release date for the Celeron 787 was announced, but this is also expected to launch in the first part of Q3 2011.
