Intel Mobile Pentium B940 is one the first three Pentium-branded mobile microprocessors, built on Sandy Bridge microarchitecture. The B940 was spotted for the first time in specifications of Hewlett Packard 431 and 630 business laptops in April 2011, and it was launched in June 2011 together with Pentium 957 and B950 CPUs. The processor is aimed at value mobile market, and it includes just enough functionality for most types of office applications, and for casual gaming.

Internally, Pentium B940 incorporates two CPU cores, with each core having dedicated 64 KB L1 cache and 256 KB L2 cache, and operating at 2 GHz. As all Sandy Bridge processors, Pentium integrates several components in addition to CPU cores:

  • 2 MB L3 cache, shared between the cores. The size of L3 cache is smaller than on Core-branded mobile microprocessors.
  • DDR3 memory controller. This controller is used to access system memory.
  • Direct Media Interface (DMI). This interface is used for communications between the CPU and peripheral devices. The DMI on the B940 model provides twice as much bandwidth, compared to previous generation of Westmere-based Pentium P6x00 CPUs.
  • On-chip graphics controller. This controller is capable of displaying HD content, but it lacks many features, found in Core-branded models, such as 3D acceleration, Quick Sync and Clear Video HD.

Although the Sandy Bridge micro-architecture comes with abundance of technologies and extensions to instruction set, many intermediate and advanced ones are disabled on Intel B940. Specifically, the processor supports 64-bit operating systems and applications, and VT-x virtualization, but doesn't support HyperThreading, Turbo Boost, AES acceleration instructions, and a few other technologies.

Pentium B940 includes the same set of low-power features, as more expensive Core i3, i5 and i7 CPUs, and has standard for mobile devices 35 Watt Thermal Design Power. The processor is manufactured in micro-PGA package, compatible with socket G2.

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.

Just got word from our suppliers, the new Lenovo G570 is now available to order and appears to be fitted with the new B940. Word is, ludicrously fast, and priced identically to the outgoing G560 with the old PDC.

I've tested one in a Toshiba C660 notebook with Aida64, it's very good for everyday use. To quickly sum it all:
In memory access it's like a Corei5 or Corei7 - yes, that fast, even with less cache!
Just in calculation tests it's slower, like a Core2Duo at about 1.8-2GHz (which is, enough for almost everything).
And in idle it's very good at power saving.
This laptop had an additional Nvidia graphics card, so I can't say anything about the integrated one.

So if you don't want to spend extra money for a new laptop, this processor will do the trick.
In everyday use you won't notice a difference (internet browsing, film watching, and in Office applications).
