Intel® Core™ i7-950

The Intel Core i7-950 is a desktop processor with 4 cores and 8 threads (45 nm process). It launched in Jun 2009. Clocks run from 3.07 GHz base to 3.33 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It uses the FCLGA1366 socket. Rated TDP is 130 W.

The Intel Core i7-950 scores 1,387 in single-core performance and 3,274 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,131 for overall performance, 4,070 for productivity performance, 4,297 for creator performance, 3,151 for engineering performance and 4,980 for gaming performance. Its multi-core throughput works out to 819 per core, 409 per thread and 25 per watt. Its computed efficiency index is 187. 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 i7-950 scores 17,207 in integer math, 7,315 in floating-point math, 71,504 in compression, 615 in cryptography, 378 in physics simulation, 2,054 in vector SIMD, 22 in the prime sieve and 9,417 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, 69% below in compression, 95% below in cryptography, 65% below in physics simulation, 87% below in vector SIMD, 67% below in the prime sieve and 58% 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 i7-950 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 3.07 GHz and boosts up to 3.33 GHz.

The Intel Core i7-950 is a desktop processor, belongs to the Intel Core i7 family and is manufactured on a 45 nm process. It launched in Jun 2009.

The Intel Core i7-950 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 i7-950 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 i7-950 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i7-950 uses the FCLGA1366 socket.

The Intel Core i7-950 has a rated TDP of 130 W.
