Pentium B940 Details

For users seeking a reliable, low-power mobile processor with integrated graphics, the Intel Pentium B940 offers a balanced solution from the early 2010s. Launched in June 2011 as part of Intel's Sandy Bridge M lineup, this processor was designed for mainstream mobile computing, emphasizing energy efficiency and basic multimedia performance. Despite its age—now over a decade old—it remains a functional option for light productivity tasks, web browsing, and media playback in older systems. Built on a 32 nm process and featuring a 35 W TDP, the B940 exemplifies Intel’s focus on power-efficient mobile computing during the transition from older architectures to more modern designs.

The Pentium B940 is a dual-core processor with no simultaneous multithreading support, operating at a base frequency of 2.0 GHz and a maximum turbo frequency of 2.2 GHz. It includes 2 MB of L3 cache and supports dual-channel DDR3-1066/DDR3-1333 memory, enabling a peak memory bandwidth of 19.87 GiB/s. With a 1667 MHz front-side bus and DMI 2.0 connectivity, the chip maintains efficient communication with the platform chipset, in this case, the Cougar Point. It is packaged in the rPGA988B socket, requiring a Socket G2 motherboard, and supports a maximum of 16 GB of RAM. The processor integrates Intel HD Graphics (Sandy Bridge), featuring 6 execution units and a base frequency of 650 MHz, with a burst frequency of up to 1100 MHz, making it capable of handling basic video playback and light graphical work.

In terms of features, the B940 supports a comprehensive set of instruction sets, including SSE4.1, SSE4.2, AVX, and AVX2, along with AES-NI for encryption acceleration and Intel Enhanced SpeedStep Technology for dynamic power scaling. It also includes Intel Flex Memory Access, which allows for flexible memory configurations, and is compatible with Intel vPro technology for enterprise environments. While the processor lacks ECC memory support and does not offer hyper-threading, it remains a stable performer for its intended use case. The chip’s 504 million transistors and 131 mm² die size reflect the design priorities of its era: efficiency over raw power.

Benchmarking reveals that the Pentium B940 holds a multicore score of 4416, placing it at #1416 out of 2060 processors, and a single-core score of 4081, ranking #1694. Its overall score of 4215 positions it at #1651 in the broader performance landscape. These results place the B940 just behind modern low-power mobile chips like the Core m3-8100Y and the Xeon D-1527, while it outperforms older desktop processors such as the Core i5-680 and FX-4350. In the Passmark tests, it scores 4488 in number crunching, 4450 in data processing, and 4475 in physics compute, all of which are modest by today's standards but typical for its generation.

As of March 2026, the Pentium B940 is best suited for legacy systems, entry-level laptops, or as a replacement in older devices where performance and power consumption are more critical than raw processing speed. It competes with similarly aged processors like the Core i5-4510U and Pentium N6000, but its lack of modern instruction set extensions and limited memory bandwidth restrict its relevance in current computing environments. For users needing more power, the processor is outclassed by contemporary CPUs in the top 50 rankings, such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which achieve over double the performance. However, for basic tasks and energy-conscious users, the B940 still holds a place in the long tail of Intel's mobile processor history.
