Intel® Celeron® 877

The Intel Celeron 877 is a laptop processor with 2 cores and 2 threads, built on the Sandy Bridge architecture. It launched in Jul 2012. A 2-MB L3 cache backs the cores (1.6 MB per core). It uses the FCBGA1023 socket. Rated TDP is 17 W.

The Intel Celeron 877 scores 630 in single-core performance and 675 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 652 for overall performance, 1,321 for productivity performance, 1,505 for creator performance, 629 for engineering performance and 2,059 for gaming performance. Its multi-core throughput works out to 338 per core, 338 per thread and 40 per watt. Its computed efficiency index is 158. Its performance index is 8, so its overall performance is 92% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Celeron 877 scores 2,654 in integer math, 1,404 in floating-point math, 12,828 in compression, 131 in cryptography, 105 in physics simulation, 445 in vector SIMD, 6 in the prime sieve and 1,714 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 95% below in integer math, 97% below in floating-point math, 94% below in compression, 99% below in cryptography, 90% below in physics simulation, 97% below in vector SIMD, 91% below in the prime sieve and 92% below in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Celeron 877 has 2 physical cores and runs 2 logical threads. It does not use a hybrid performance and efficiency core layout. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.40 GHz.

The Intel Celeron 877 is a laptop processor, belongs to the Intel Celeron family, uses the Sandy Bridge architecture and carries the codename Sandy Bridge. It launched in Jul 2012.

The Intel Celeron 877 has 256 KB of L1 cache, 1 MB of L2 cache and 2 MB of L3 cache. That adds up to about 3.3 MB of cache, or 1.63 MB per core.

The Intel Celeron 877 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 2 MB. L3 is the largest level and makes up about 62% of the cache listed here.

The Intel Celeron 877 includes integrated graphics (HD Graphics (6 EUs)) and clocks the graphics up to 1.00 GHz.

The Intel Celeron 877 uses the FCBGA1023 socket.

The Intel Celeron 877 has a rated TDP of 17 W.
