Intel® Xeon™ E3-1220 v5

The Intel Xeon E3-1220 v5 is a server processor with 4 cores and 4 threads, built on the Skylake architecture. It launched in Oct 2015. Clocks run from 3.0 GHz base to 3.5 GHz boost. A 8-MB L3 cache backs the cores (2.2 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 80 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Xeon E3-1220 v5 scores 2,009 in single-core performance and 5,697 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,383 for overall performance, 6,516 for productivity performance, 6,750 for creator performance, 5,483 for engineering performance and 7,451 for gaming performance. Its multi-core throughput works out to 1,424 per core, 1,424 per thread and 71 per watt. Its computed efficiency index is 378. Its performance index is 42, so its overall performance is 58% 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 E3-1220 v5 scores 14,615 in integer math, 12,564 in floating-point math, 74,937 in compression, 1,690 in cryptography, 499 in physics simulation, 6,644 in vector SIMD, 36 in the prime sieve and 9,320 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 75% below in integer math, 73% below in floating-point math, 67% below in compression, 85% below in cryptography, 54% below in physics simulation, 57% below in vector SIMD, 46% below in the prime sieve and 59% 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 E3-1220 v5 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 3.00 GHz and boosts up to 3.50 GHz.

The Intel Xeon E3-1220 v5 is a server processor, belongs to the Intel Xeon E3 family, uses the Skylake architecture, carries the codename Skylake and is manufactured on a 14 nm process. It launched in Oct 2015.

The Intel Xeon E3-1220 v5 has 128 KB of L1 cache, 512 KB of L2 cache and 8 MB of L3 cache. That adds up to about 8.6 MB of cache, or 2.16 MB per core.

The Intel Xeon E3-1220 v5 has a 3-level cache hierarchy: L1 at 128 KB, L2 at 512 KB and L3 at 8 MB. L3 is the largest level and makes up about 93% of the cache listed here.

The Intel Xeon E3-1220 v5 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 Xeon E3-1220 v5 uses the FCLGA1151 socket, supports PCI Express 3.0 and provides up to 16 PCIe lanes.

The Intel Xeon E3-1220 v5 has a rated TDP of 80 W.
