Pentium B950 Details

The Intel Pentium B950, launched in June 2011, sits firmly in the realm of legacy mobile processors, now over a decade old. As of March 2026, it is not competitive with modern CPUs in any meaningful way, yet it remains a representative example of Intel's Sandy Bridge architecture in the low-power mobile space. With a single-core score of 4092 and a multicore score of 4397, the B950 ranks #1683 and #1462 respectively out of 2060 processors in its benchmark set, highlighting its position as a low-end performer by today's standards. Its overall score of 4214 places it at #1653, just behind its close sibling, the Pentium B940, and slightly above the Pentium P6300. While it may have offered decent efficiency at launch, the B950 now serves more as a historical artifact than a practical choice for current computing needs.

The processor is built on Intel’s 32 nm Sandy Bridge microarchitecture and features a 2.1 GHz base clock, 2 MB of L3 cache, and a 35 W TDP. It is designed for mobile systems using the Socket G2 (rPGA988B) and supports dual-channel DDR3-1333/1066 memory, delivering up to 19.87 GiB/s of memory bandwidth. The CPU includes Intel’s integrated HD Graphics (Sandy Bridge) with a base frequency of 650 MHz and a burst frequency of 1100 MHz, capable of driving up to two displays. Despite its age, the B950 supports a broad range of instruction sets, including SSE4.1, SSE4.2, AVX, and AES-NI, making it capable of handling basic multimedia and encryption tasks from its era.

In terms of performance, the B950’s single-core score is notably weaker than its multicore performance, a trend that reflects its design focus on basic multitasking rather than raw power. While it outperforms older Celeron and Core 2 Duo models, it falls well behind modern low-power processors like the Core i3-2375M or even the Atom C3338. Its multicore performance is competitive with other Sandy Bridge-era Pentiums and Core i5-430M, but it is significantly outpaced by contemporary CPUs. The lack of hyper-threading and a modest core count further limit its ability to scale in multi-threaded applications.

Overall, the Intel Pentium B950 is best suited for legacy systems, light office tasks, or as a replacement in older laptops where integrated graphics and low power consumption are priorities. While it may still function in niche scenarios, its age and performance limitations make it obsolete in any modern computing context. For users seeking efficiency or performance today, even entry-level modern processors offer vastly superior capabilities.
