Pentium 957 Details

Built on Intel's Sandy Bridge microarchitecture and fabricated on a 32 nm process, the Pentium 957 represents a mobile processor from the early 2010s, released in June 2011. While now considered a legacy device, it was designed for energy-efficient performance in thin and light notebooks. As of March 2026, the Pentium 957 is no longer relevant in modern computing due to its outdated architecture and limited capabilities compared to contemporary processors. Nevertheless, it remains a notable example of Intel's efforts to deliver integrated graphics and balanced performance in the mobile market segment during that era.

The Pentium 957 features two cores and two threads, with a base clock of 1.2 GHz and a locked multiplier, which restricts overclocking potential. It operates at a TDP of 17 W, making it suitable for low-power systems where thermal constraints are critical. The processor supports DDR3-1333 and DDR3-1066 memory through a dual-channel interface, with a maximum memory bandwidth of 19.87 GiB/s and a cap of 8 GB of RAM. It uses a BGA1023 package and supports DMI 2.0 at 5000 MT/s, providing a stable connection to the chipset.

Cache hierarchy includes 64 KiB of L1 instruction and data cache per core, 512 KiB of L2 cache, and a shared 2 MiB L3 cache. Despite its modest cache sizes by today’s standards, the Sandy Bridge architecture provided efficient data access for its time. Integrated into the chip is the Intel HD Graphics (Sandy Bridge) GPU, featuring six execution units, a base frequency of 350 MHz, and a burst frequency of up to 800 MHz. It supports up to two displays and is capable of handling basic multimedia tasks and light gaming.

The Pentium 957 supports a wide range of instruction sets, including x86-64, SSE4.1, SSE4.2, AVX, and AVX2, enabling it to run modern software of its era. It also includes features like Intel Enhanced SpeedStep Technology for power management and Intel Flex Memory Access for improved memory flexibility. However, it lacks simultaneous multithreading and ECC memory support, limiting its scalability in professional environments.

In benchmark testing, the Pentium 957 achieves an Overall Score of 4145, ranking #1749 of 2060, with a Singlecore Score of 3895 (#1832) and a Multicore Score of 4520 (#1193). Its performance is comparable to older mobile processors like the Core i5-2467M and Core i3-3250, though it falls behind more recent low-power designs. The multicore score suggests stronger scaling than single-core performance, indicating that the processor benefits from multi-threaded workloads more than single-threaded ones.

Given its age and modest performance, the Pentium 957 is best suited for legacy systems, light office tasks, or educational use. It is not suitable for modern applications, gaming, or content creation. As of 2026, it serves as a historical artifact in Intel’s mobile processor lineage rather than a practical choice for new builds.
