Intel® Core™ i7-3930K

The Intel Core i7-3930K is a desktop processor with 6 cores and 12 threads, built on the Sandy Bridge architecture (32 nm process). It launched in Oct 2011. Clocks run from 3.2 GHz base to 3.8 GHz boost. A 12-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR3 memory up to 64.23 GB across 4 channels. The chip drops into the FCLGA2011 socket and exposes PCIe 2.0 (40 lanes). Rated TDP is 130 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i7-3930K scores 1,736 in single-core performance and 8,177 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,768 for overall performance, 7,745 for productivity performance, 7,622 for creator performance, 8,126 for engineering performance and 7,252 for gaming performance. Its multi-core throughput works out to 1,363 per core, 681 per thread and 63 per watt. Its computed efficiency index is 330. Its performance index is 47, so its overall performance is 53% 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 i7-3930K scores 32,196 in integer math, 11,969 in floating-point math, 138,303 in compression, 2,514 in cryptography, 664 in physics simulation, 6,192 in vector SIMD, 38 in the prime sieve and 20,326 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 45% below in integer math, 74% below in floating-point math, 39% below in compression, 78% below in cryptography, 39% below in physics simulation, 60% below in vector SIMD, 43% below in the prime sieve and 10% 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 i7-3930K has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 3.80 GHz.

The Intel Core i7-3930K is a desktop processor, belongs to the Intel Core i7 family, uses the Sandy Bridge architecture, carries the codename Sandy Bridge E and is manufactured on a 32 nm process. It launched in Oct 2011.

The Intel Core i7-3930K has 384 KB of L1 cache, 1.50 MB of L2 cache and 12 MB of L3 cache. That adds up to about 13.9 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i7-3930K has a 3-level cache hierarchy: L1 at 384 KB, L2 at 1.5 MB and L3 at 12 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Core i7-3930K supports DDR3 memory, addresses up to 64 GB of memory, uses 4 memory channels, runs memory at up to 1,600 MT/s and delivers up to 51.2 GB/s of memory bandwidth. It does not support DDR5, DDR4 and LPDDR memory.

The Intel Core i7-3930K does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i7-3930K uses the FCLGA2011 socket, supports PCI Express 2.0 and provides up to 40 PCIe lanes.

The Intel Core i7-3930K has a rated TDP of 130 W.
