Intel Mobile Celeron 847 is the first ultra-low voltage (ULV)
budget microprocessor, built on Sandy Bridge microarchitecture. The
processor is aimed at entry-level thin and light notebooks, and it was
launched in June 2011 along with several Core i5 and Core i7 ULV models.
Manufactured using the latest (as of
Q3 2011) 32nm process, the Celeron 847 combines several key
components on a single die: CPU cores with L3 cache, graphics
processing unit (GPU), memory controller, Direct Media Interface, and
PCI Express interface. The microprocessor runs at at 1.1 GHz, and has
dedicated 64 KB L1 and 256 KB L2 caches per each core. 2 MB L3 cache
is shared between the cores, and with the graphics processing unit.
The GPU is HD-capable, but doesn't support 3D acceleration and several
video processing technologies, reserved for more expensive processors.
On-chip memory controller has two channels, and works with DDR3 memory
with data rates up to 1333 MHz. The CPU cores support
64-bit instructions, and SIMD streaming extensions up to SSE4, but not
recently introduced AES and AVX instructions. Intel 847 incorporates
all basic Sandy Bridge technologies, such as Virtualization, and lacks
Hyper-Threading, Turbo Boost and other advanced features.
While the 1.1 GHz clock frequency of the Celeron 847 may be
considered low, and sufficient only for basic office tasks, the CPU
has one major advantage over mainstream Celeron B8xx parts - ultra low
power consumption. Thermal Design Power of this chip is 17 Watt, and
that accounts for the CPU cores, the GPU and other components. The
Intel 847 utilizes a handful of techniques to reduce power
consumption, including lower processor frequency and core voltage.
These techniques also include low-power states, invoked when one or
two cores are non-operational, and Enhanced SpeedStep technology, used
by cores in active state.
The Celeron 847 is manufactured in a BGA package, which is soldered
directly on a motherboard, and cannot be replaced or upgraded.
