Intel® Core™ 2 Duo E6540

The Intel Core 2 Duo E6540 is a desktop processor with 2 cores and 2 threads. It launched in Jul 2007. It uses the FCLGA775 socket. Rated TDP is 65 W.

The Intel Core 2 Duo E6540 scores 969 in single-core performance and 808 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 885 for overall performance, 1,882 for productivity performance, 2,189 for creator performance, 752 for engineering performance and 3,109 for gaming performance. Its multi-core throughput works out to 404 per core, 404 per thread and 12 per watt. Its computed efficiency index is 110. Its performance index is 11, so its overall performance is 89% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the Intel Core 2 Duo E6540.

The Intel Core 2 Duo E6540 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 2.33 GHz.

The Intel Core 2 Duo E6540 is a desktop processor and belongs to the Intel Core 2 family. It launched in Jul 2007.

The Intel Core 2 Duo E6540 has 128 KB of L1 cache and 4 MB of L2 cache. That adds up to about 4.1 MB of cache, or 2.06 MB per core.

The Intel Core 2 Duo E6540 has a 2-level cache hierarchy: L1 at 128 KB and L2 at 4 MB. L2 is the largest level and makes up about 97% of the cache listed here.
