Intel® Core™ i5-7640X X-series

The Intel Core i5-7640X X-series is a desktop processor with 4 cores and 4 threads, built on the Kaby Lake architecture. It launched in Apr 2017. Clocks run from 4.0 GHz base to 4.2 GHz boost. A 6-MB L3 cache backs the cores (1.8 MB per core). It addresses DDR4 memory up to 64 GB across 2 channels. The chip drops into the FCLGA2066 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 112 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i5-7640X X-series scores 2,548 in single-core performance and 7,119 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,259 for overall performance, 8,195 for productivity performance, 8,502 for creator performance, 6,852 for engineering performance and 9,424 for gaming performance. Its multi-core throughput works out to 1,780 per core, 1,780 per thread and 64 per watt. Its computed efficiency index is 402. Its performance index is 53, so its overall performance is 47% 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 i5-7640X X-series scores 18,839 in integer math, 16,022 in floating-point math, 94,342 in compression, 2,101 in cryptography, 568 in physics simulation, 8,432 in vector SIMD, 34 in the prime sieve and 11,923 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 68% below in integer math, 65% below in floating-point math, 59% below in compression, 82% below in cryptography, 48% below in physics simulation, 46% below in vector SIMD, 49% below in the prime sieve and 47% 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 i5-7640X X-series has 4 physical cores and runs 4 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 4.00 GHz and boosts up to 4.20 GHz.

The Intel Core i5-7640X X-series is a desktop processor, belongs to the Intel Core i5 family, uses the Kaby Lake architecture, carries the codename Kaby Lake and is manufactured on a 14 nm process. It launched in Apr 2017.

The Intel Core i5-7640X X-series has 256 KB of L1 cache, 1 MB of L2 cache and 6 MB of L3 cache. That adds up to about 7.3 MB of cache, or 1.81 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i5-7640X X-series has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 6 MB. L3 is the largest level and makes up about 83% of the cache listed here.

The Intel Core i5-7640X X-series supports DDR4 memory, addresses up to 64 GB of memory and uses 2 memory channels. It does not support DDR5 and LPDDR memory.

The Intel Core i5-7640X X-series does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i5-7640X X-series uses the FCLGA2066 socket, supports PCI Express 3.0 and provides up to 16 PCIe lanes.

The Intel Core i5-7640X X-series has a rated TDP of 112 W.
