Intel Mobile Celeron 857 - AV8062701149001 / AV8062701022701
Intel Celeron 857 is a ultra-low voltage mobile processor for
budget thin-and-light notebooks. The CPU is expected to launch in the
third quarter 2011. This microprocessor is marginally faster than the
Celeron 847, which was introduced in June 2011.
Intel Mobile Celeron 857 is built on Sandy Bridge
microarchitecture, which integrates the following components:
- Two CPU cores, with each core having its own 64 KB level 1
and 256 KB level 2 caches.
- 2 MB level 3 cache. The L3 cache is shared between the cores and
an integrated graphics controller.
- Graphics Processing Unit. The GPU can handle HD video content,
but it lacks Quick Sync and Clear Video HD video processing
technologies, and it doesn't support 3D Video or 3D graphics
- DDR3 memory controller supports two channels with
data rates up to 1333 MHz.
- Direct Media Interface (DMI) 2.0 is used is to
communicate with South Bridge chip and all peripheral devices. The DMI
2.0 in Sandy Bridge chips delivers twice as much bandwidth as the DMI
in the previous generation of Westmere microprocessors.
- PCI Express Interface.
The Intel 857 is clocked at 1.2 GHz, and, lacking Hyper-Threading
technology, can execute only one thread per each core. Being a budget
processor, the Celeron does not support any advanced, or even
intermediate technologies, such as AES and AVX instructions, or Turbo
Boost and Vpro. The CPU does include basic features, like Execute
Disable bit and Intel 64, that are extensively used by modern
operating systems. Low-power features on this Mobile Celeron are
comprised of Enhanced SpeedStep technology, which reduces power
consumption of active cores by lowering their frequency and operating
voltage, and a few low-power states, used when one or two cores are
idle. Thermal Design Power of this CPU is 17 Watt.
Intel Celeron 857 is manufactured in a Ball Grid Array (BGA)
package, which has lower profile and smaller size than PGA packages.
Main disadvantage of this package is that the BGA CPUs are usually
soldered on a mainboard, and cannot be easily replaced or upgraded.

Intel to retire Sandy Bridge mobile processors
Jan 15, 2013
: Intel plans to discontinue a handful of Sandy Bridge microprocessors,
including Core i5, i7 and Celeron ultra low voltage models, and quad-core Core i7
microprocessors. The processors will be end-of-lifed in the middle of this year,
after the company completes transition to ivy Bridge microarchitecture
and releases first Haswell mobile CPUs. Model numbers of affected
processors were published today in two Product Change Notifications (PCNs).
Intel introduced Celeron 857 CPU
Jul 08, 2011
: At the end of June, we published specifications of two upcoming
Celeron 787 and 857 ultra-low voltage (ULV) microprocessors. One of
these CPUs, dual-core Celeron 857, was launched last weekend. On
Sunday, Intel added this model to official price list, and later in
the week the CPU was also added to the ARK Intel database. There are
no indications yet that another forthcoming ULV microprocessor,
single-core Celeron 787, was released this week.
Intel Celeron 787 and 857 CPUs are on the way
Jun 27, 2011
: After several product launches in January, February and June of
this year, Intel gradually replaced most of Westmere mobile processors
with models, built on the latest Sandy Bridge microarchitecture. Intel
Celeron line-up still includes two low budget SKUs, Celeron 763 and
925, based on three-year old Penryn core. Those will be replaced soon.
The mainstream 925 will be superseded by Celeron B710, which is coming
in the third quarter 2011. Also in the Q3, Intel will introduce two
ultra-low voltage Celeron 787 and 857 processors, and the 787 model
will displace Celeron 763.
