Pentium 987 Details

The Intel Pentium 987, launched in February 2013, occupies a niche in the mobile processor landscape as a budget-oriented CPU built on the Sandy Bridge microarchitecture. While it is now a legacy device by modern standards, its performance remains relevant in low-power, entry-level computing scenarios. With a single-core score of 3814 and a multicore score of 4250, the Pentium 987 ranks 1877th and 1905th respectively among 2060 processors in the benchmark database, placing it firmly in the lower tier of desktop and mobile CPUs. Its overall score of 3988 positions it just ahead of older dual-core processors like the Athlon 64 X2 4400+ and the Celeron N3350, but behind more capable chips such as the Core 2 Duo T7700 and the Phenom X4 9650.

The processor is a dual-core chip with a base frequency of 1.5 GHz and no turbo boost capability, due to a locked multiplier. It operates on a 32 nm process node and features a 2 MB L3 cache, complemented by 0.5 MB of L2 cache and 0.125 MB of L1 cache. The integrated Intel HD Graphics (Sandy Bridge) GPU runs at 350 MHz with a burst frequency of up to 1000 MHz and supports two displays, making it suitable for basic multimedia tasks. The CPU supports dual-channel DDR3-1333 and DDR3-1066 memory, with a maximum memory capacity of 16 GB and a peak memory bandwidth of 19.87 GB/s.

Despite its age, the Pentium 987 demonstrates efficiency with a TDP of just 17 W, enabling use in thin and light mobile systems. It includes a variety of instruction set extensions, including SSE4.1, SSE4.2, AVX, and AES-NI, ensuring compatibility with older software and basic encryption workloads. However, it lacks hyper-threading, limiting its ability to handle multitasking workloads efficiently. The processor is packaged in a BGA 1023 socket and relies on Intel's Enhanced SpeedStep technology for power management.

In comparison to its immediate competitors, the Pentium 987 outperforms some Atom and Celeron variants but falls behind mid-range Core i5 and Athlon processors from the same era. Its single-core performance is slightly better than that of the Intel Core i7-820QM, yet it trails behind the Celeron 2955U and the Turion II Neo N40L. In multicore performance, it edges out the Core 2 Duo T7600 and the Atom N570, but is outpaced by the Core i5-2410M and the A4-1200.

As of March 2026, the Pentium 987 remains a relic of early 2010s mobile computing, suitable only for basic office tasks, web browsing, and media playback. It is not competitive in modern workloads such as video editing or gaming, and its performance is overshadowed by today’s top-tier CPUs, which exceed 8,000 in single-core and 12,000 in multicore scores. Nevertheless, for users requiring a low-cost, energy-efficient solution in legacy systems, the Pentium 987 still holds modest utility.
