Intel® Core™ i7-870

The Intel Core i7-870 is a desktop processor with 4 cores and 8 threads (45 nm process). It launched in Sep 2009. Clocks run from 2.93 GHz base to 3.6 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). The chip drops into the FCLGA1156 socket and exposes PCIe 2.0 (16 lanes). Rated TDP is 95 W.

The Intel Core i7-870 scores 1,383 in single-core performance and 3,173 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,095 for overall performance, 3,999 for productivity performance, 4,235 for creator performance, 3,054 for engineering performance and 4,942 for gaming performance. Its multi-core throughput works out to 793 per core, 397 per thread and 33 per watt. Its computed efficiency index is 215. Its performance index is 26, so its overall performance is 74% 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 Core i7-870 scores 16,980 in integer math, 7,292 in floating-point math, 67,972 in compression, 596 in cryptography, 356 in physics simulation, 1,980 in vector SIMD, 22 in the prime sieve and 9,079 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 71% below in integer math, 84% below in floating-point math, 70% below in compression, 95% below in cryptography, 67% below in physics simulation, 87% below in vector SIMD, 67% below in the prime sieve and 60% 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 Core i7-870 has 4 physical cores and runs 8 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.93 GHz and boosts up to 3.60 GHz.

The Intel Core i7-870 is a desktop processor, belongs to the Intel Core i7 family and is manufactured on a 45 nm process. It launched in Sep 2009.

The Intel Core i7-870 has 256 KB of L1 cache, 1 MB of L2 cache and 8 MB of L3 cache. That adds up to about 9.3 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i7-870 has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 8 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Core i7-870 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i7-870 uses the FCLGA1156 socket, supports PCI Express 2.0 and provides up to 16 PCIe lanes.

The Intel Core i7-870 has a rated TDP of 95 W.
