Intel® Xeon™ E7-8891 v3

The Intel Xeon E7-8891 v3 is a server processor with 10 cores and 20 threads, built on the Haswell architecture. It launched in Apr 2015. Clocks run from 2.8 GHz base to 3.5 GHz boost. A 45-MB L3 cache backs the cores (4.9 MB per core). It addresses DDR4, DDR3 memory up to 1536 GB across 4 channels. The chip drops into the FCLGA2011 socket and exposes PCIe 3.0 (32 lanes). Rated TDP is 165 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon E7-8891 v3 scores 1,715 in single-core performance and 21,615 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,088 for overall performance, 16,451 for productivity performance, 14,975 for creator performance, 22,831 for engineering performance and 10,549 for gaming performance. Its multi-core throughput works out to 2,162 per core, 1,081 per thread and 131 per watt. Its computed efficiency index is 474. Its performance index is 75, so its overall performance is 25% 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 E7-8891 v3 scores 72,163 in integer math, 51,570 in floating-point math, 337,691 in compression, 6,279 in cryptography, 2,669 in physics simulation, 29,226 in vector SIMD, 202 in the prime sieve and 46,685 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 23% above in integer math, 12% above in floating-point math, 48% above in compression, 45% below in cryptography, 145% above in physics simulation, 88% above in vector SIMD, 201% above in the prime sieve and 106% above 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 E7-8891 v3 has 10 physical cores and runs 20 logical threads. It runs 2 threads per core. It runs at a base clock of 2.80 GHz and boosts up to 3.50 GHz.

The Intel Xeon E7-8891 v3 is a server processor, belongs to the Intel Xeon E7 family, uses the Haswell architecture, carries the codename Haswell and is manufactured on a 22 nm process. It launched in Apr 2015.

The Intel Xeon E7-8891 v3 has 1.25 MB of L1 cache, 2.50 MB of L2 cache and 45 MB of L3 cache. That adds up to about 48.8 MB of cache, or 4.88 MB per core.

The Intel Xeon E7-8891 v3 has a 3-level cache hierarchy: L1 at 1.3 MB, L2 at 2.5 MB and L3 at 45 MB. L3 is the largest level and makes up about 92% of the cache listed here.

The Intel Xeon E7-8891 v3 supports DDR4, DDR3 memory, addresses up to 1,536 GB of memory, uses 4 memory channels, runs memory at up to 1,866 MT/s and delivers up to 59.7 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon E7-8891 v3 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon E7-8891 v3 uses the FCLGA2011 socket, supports PCI Express 3.0 and provides up to 32 PCIe lanes.

The Intel Xeon E7-8891 v3 has a rated TDP of 165 W.
