Intel® Xeon™ E3-1240 v6

The Intel Xeon E3-1240 v6 is a server processor with 4 cores and 8 threads, built on the Kaby Lake architecture. It launched in Jan 2017. Clocks run from 3.7 GHz base to 4.1 GHz boost. A 8-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 64 GB across 2 channels. The chip drops into the FCLGA1151 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 72 W. Notable platform capabilities: Extended Page Tables (EPT). Feex currently counts 1 machine in its hardware fleet with exactly this processor.

The Intel Xeon E3-1240 v6 scores 2,378 in single-core performance and 8,757 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,563 for overall performance, 9,021 for productivity performance, 9,097 for creator performance, 8,429 for engineering performance and 9,323 for gaming performance. Its multi-core throughput works out to 2,189 per core, 1,095 per thread and 122 per watt. Its computed efficiency index is 538. Its performance index is 57, so its overall performance is 43% 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 Xeon E3-1240 v6 scores 27,670 in integer math, 17,198 in floating-point math, 120,176 in compression, 3,053 in cryptography, 621 in physics simulation, 8,208 in vector SIMD, 30 in the prime sieve and 15,297 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 53% below in integer math, 63% below in floating-point math, 47% below in compression, 73% below in cryptography, 43% below in physics simulation, 47% below in vector SIMD, 55% below in the prime sieve and 32% 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 Xeon E3-1240 v6 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 3.70 GHz and boosts up to 4.10 GHz.
