Intel Mobile Celeron B800 is a dual-core budget microprocessor for entry-level notebooks. Like other B8xx-series CPUs, the B800 is built on Sandy Bridge microarchitecture, and uses three-level cache architecture. Each CPU core has dedicated 64 KB first level and 256 KB second level caches. The cores share 2 MB third level cache, which is also shared with integrated graphics processing unit (GPU). Intel B800 operates at 1.5 GHz, while the GPU has 650 MHz clock rate, boosted to 1000 MHz in Turbo mode. To access system memory, the Celeron uses on-die dual-channel memory controller, that supports DDR3 memory with data rates up to 1333 MHz. Two other components on the B800 chip are Direct Media Interface, which is used to communicate with South Bridge chip and all peripherals, and PCI Express 2.0 interface.

As a budget model, Intel Celeron B800 lacks many Sandy Bridge features, reserved for more expensive Core brands. This model has Virtualization, but doesn't include HyperThreading, Turbo Boost or VPro technologies. The B800 includes SSE3 and Intel 64 extensions to instruction set, but not AES or 256-bit AVX instructions. On-chip GPU is capable of displaying High Definition content, however it doesn't support 3D acceleration, Quick Sync, Clear Video HD and InTru 3D technologies.

Low-power features on the Celeron B800 are identical to those in Sandy Bridge Pentium and Core microprocessors. The CPU has several low-power states, used to save battery power while one or more cores are idle. Intel B800 also supports Enhanced SpeedStep technology, that can reduce power consumption of operational cores by slowing them down, and lowering their core voltage. This processor has 35 Watt Thermal Design Power, which includes power dissipated by the CPU cores, integrated graphics and other chip components.

The Celeron B800 processor is manufactured in micro-PGA package, compatible with socket G2. It's likely that this processor can be upgraded to faster socket G2 CPUs. Mobile Pentiums have slightly higher core frequency, and 50% larger size of L3 cache. Core i3s have even higher clock speeds, and they add Hyper-Threading technology and new AVX instructions. Core i5s and i7s have additional Turbo Boost and Vpro technologies on top of all Core i3 features.

Intel introduces mobile CPUs: part II
Jun 21, 2011: Yesterday, Intel posted new pricelist with four new ultra-low voltage consumer processors from Celeron, Core i3 and Core i5 families. We used this update as a base for yesterday's story, where we reported that more parts may surface in an official announcement, or in the Intel ARK product database. Today, several processors were added to the ARK database, including two new models that we hadn't covered before. The products, added to the database, are embedded Celeron 847E and B810E, consumer-class Celeron B800, Pentium B940 and B950, as well as 4 CPUs, previously found in the pricelist - Celeron 847, Core i5-2557M, Core i7-2637M and i7-2677M. Two new SKUs are Pentium 957 and Core i5-2467M.

Intel mobile CPUs to launch in June 2011
Jun 16, 2011: In the past few months, we published several stories detailing soon to be released Sandy Bridge mobile microprocessors. The stories referred to budget Celeron and Pentium CPUs, mainstream Core-branded processors for mid-class laptops, and ultra low voltage (ULV) 2nd generation Core chips for thin and light notebooks. Using notebook product availability dates, our sources, and information, previously disclosed by Fudzilla, we came up with a list of processors that will be launched this month. The list includes ULV Celeron 847, embedded Celeron 847E and B810E, Pentium B940, embedded Core i3-2330E and i3-2340UE, and ULV Core i5-2557M, i7-2637M and i7-2677M.

Intel Celeron B710 and B800 CPUs in Q3 2011
Jun 10, 2011: In March 2011, Intel introduced the first, and so far the only one, mobile Celeron processor with Sandy Bridge core. From previously published stories you may know that there are four other planned Celeron microprocessors, ultra-low power 847, and three embedded models, 827E, 847E and B810E. According to roadmap documents we've seen, there will be two additional consumer class Celeron SKUs, B710 and B810, available in the third quarter 2011.
