Intel® Core™ i7-920XM

The Intel Core i7-920XM is a laptop processor with 4 cores and 8 threads (45 nm process). It launched in Sep 2009. Clocks run from 2.0 GHz base to 3.2 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It supports DDR3 memory. Rated TDP is 55 W.

The Intel Core i7-920XM scores 1,068 in single-core performance and 2,032 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,473 for overall performance, 2,816 for productivity performance, 3,040 for creator performance, 1,956 for engineering performance and 3,712 for gaming performance. Its multi-core throughput works out to 508 per core, 254 per thread and 37 per watt. Its computed efficiency index is 199. Its performance index is 18, so its overall performance is 82% 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 i7-920XM scores 10,814 in integer math, 4,879 in floating-point math, 42,163 in compression, 362 in cryptography, 315 in physics simulation, 1,205 in vector SIMD, 18 in the prime sieve and 5,887 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 82% below in integer math, 89% below in floating-point math, 82% below in compression, 97% below in cryptography, 71% below in physics simulation, 92% below in vector SIMD, 73% below in the prime sieve and 74% 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 i7-920XM 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 2.00 GHz and boosts up to 3.20 GHz.

The Intel Core i7-920XM is a laptop processor, belongs to the Intel Core i7 family and is manufactured on a 45 nm process. It launched in Sep 2009.

The Intel Core i7-920XM 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 i7-920XM 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 i7-920XM supports DDR3 memory, uses 2 memory channels, runs memory at up to 1,333 MT/s and delivers up to 21.3 GB/s of memory bandwidth. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Core i7-920XM does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i7-920XM supports PCI Express 2.0 and provides up to 16 PCIe lanes.

The Intel Core i7-920XM has a rated TDP of 55 W.
