Intel® Core™ 2 Quad Q9450

The Intel Core 2 Quad Q9450 is a desktop processor with 4 cores and 4 threads. It launched in Mar 2008. It uses the FCLGA775 socket. Rated TDP is 95 W.

The Intel Core 2 Quad Q9450 scores 1,128 in single-core performance and 2,210 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 1,579 for overall performance, 3,016 for productivity performance, 3,246 for creator performance, 2,127 for engineering performance and 3,937 for gaming performance. Its multi-core throughput works out to 553 per core, 553 per thread and 23 per watt. Its computed efficiency index is 162. Its performance index is 20, so its overall performance is 80% 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 2 Quad Q9450 scores 10,150 in integer math, 5,713 in floating-point math, 45,553 in compression, 544 in cryptography, 226 in physics simulation, 818 in vector SIMD, 18 in the prime sieve and 5,968 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 83% below in integer math, 88% below in floating-point math, 80% below in compression, 95% below in cryptography, 79% below in physics simulation, 95% 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 2 Quad Q9450 has 4 physical cores and runs 4 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 2.66 GHz.

The Intel Core 2 Quad Q9450 is a desktop processor and belongs to the Intel Core 2 family. It launched in Mar 2008.

The Intel Core 2 Quad Q9450 has 256 KB of L1 cache and 12 MB of L2 cache. That adds up to about 12.3 MB of cache, or 3.06 MB per core.

The Intel Core 2 Quad Q9450 has a 2-level cache hierarchy: L1 at 256 KB and L2 at 12 MB. L2 is the largest level and makes up about 98% of the cache listed here.
