Celeron 877 Details

The Intel Celeron 877, launched in July 2012, stands as a relic of the early Sandy Bridge era, offering modest performance by modern standards. With a release price of $86 and a TDP of just 17W, it was designed for low-power mobile systems where power efficiency and cost were prioritized over raw performance. As of March 2026, the processor is nearly 14 years old, placing it far behind contemporary CPUs in both architecture and performance, but it remains a notable example of Intel’s mobile strategy during the early 2010s.

At its core, the Celeron 877 features a dual-core, dual-thread design built on the Sandy Bridge microarchitecture at a 32 nm process. It operates at a base frequency of 1.4 GHz, with a locked multiplier limiting overclocking potential. The processor includes 2 MB of L3 cache and supports DDR3-1066/1333 memory in a dual-channel configuration, achieving a maximum memory bandwidth of 19.87 GiB/s. Despite its age, it supports modern technologies such as Intel Enhanced SpeedStep, Intel VT-x, and AES-NI, ensuring compatibility with basic virtualization and encryption tasks.

Integrated graphics are handled by Intel HD Graphics (Sandy Bridge), which runs at 350 MHz base frequency and can boost to 1 GHz. The GPU includes 6 execution units and supports up to two displays, making it suitable for light multimedia use and office productivity. However, it lacks the power for gaming or high-resolution video editing.

In benchmark testing, the Celeron 877 achieves an overall score of 3975, ranking #1912 out of 2060 processors, with a single-core score of 3790 (#1896) and a multicore score of 4253 (#1894). These results place it slightly above its immediate predecessor, the Celeron 867, and just below the Celeron 900, though it trails behind even modest modern low-power processors like the Atom Z3770. Its strongest performance lies in single-core tasks, where it competes with older AMD and Intel mobile chips, but it falls significantly behind current mainstream and high-end CPUs.

When compared to the top 50 processors in each category, the Celeron 877 is outperformed by orders of magnitude. For example, the highest-ranking CPU in the overall list, the Ryzen Threadripper PRO 9995WX, scores over 9,400, more than double the Celeron’s performance. Even the top single-core performer, the Core Ultra 9 285K, scores over 8,700, over 2.3 times higher than the Celeron’s single-core score.

In conclusion, the Intel Celeron 877 is best suited for legacy systems, basic computing tasks, or embedded applications where power efficiency and low cost are more important than performance. While it was once a viable option for entry-level mobile devices, it now serves as a historical benchmark of Intel’s mobile processor evolution, offering little more than minimal functionality in today’s computing landscape.
