Celeron 857 Details

The Intel Celeron 857, launched in July 2011, represents a significant step down from its high-performance contemporaries, yet it carved a niche in the mobile market as a power-efficient, budget-friendly processor. Built on Intel’s Sandy Bridge microarchitecture at a 32 nm process, the Celeron 857 features a dual-core design with no simultaneous multithreading support, operating at a base frequency of 1.2 GHz and a maximum turbo frequency of 1.2 GHz. Despite its modest performance, it delivers a low TDP of 17 W, making it ideal for thin-and-light laptops where power consumption and thermal output are critical. The processor supports DDR3-1066 and DDR3-1333 memory over a dual-channel interface, with a maximum memory capacity of 16 GB and a peak bandwidth of 19.87 GB/s.

It includes 2 MB of L3 cache, 0.5 MB of L2 cache, and 0.125 MB of L1 cache, distributed across its two cores. The integrated Intel HD Graphics (Sandy Bridge) GPU runs at a base frequency of 350 MHz, with a burst frequency of up to 1000 MHz, supporting up to two displays and offering basic multimedia and light gaming capabilities. The Celeron 857 is packaged in a BGA1023 socket and supports key technologies such as Intel Enhanced SpeedStep, Intel VT-x, and Intel Flex Memory Access, though it lacks ECC memory support and a locked multiplier. In benchmark testing, the processor scores 3809 overall, placing it at #2014 of 2060 in the overall ranking, with a single-core score of 3696 (#1943) and a multicore score of 3978 (#2058).

It trails behind modern processors and even older dual-core CPUs like the Core 2 Duo T9500 and Athlon 64 X2 5000+, indicating its limited competitiveness in today’s computing landscape. As of March 2026, the Celeron 857 is best suited for basic productivity tasks, web browsing, and media playback in legacy or entry-level devices. While its performance is now outdated, its low power consumption and integrated graphics make it a viable option in specific niche scenarios where energy efficiency and cost are paramount.
