Intel® Pentium® Silver J5040

The Intel Pentium Silver J5040 is a laptop processor with 4 cores and 4 threads, built on the Gemini Lake architecture. It launched in Oct 2019. Clocks run from 2.0 GHz base to 3.2 GHz boost. A 4-MB L3 cache backs the cores (2.1 MB per core). It addresses DDR4, LPDDR4 memory up to 8 GB across 2 channels. The chip drops into the FCBGA1090 socket and exposes PCIe 2.0 (6 lanes). Rated TDP is 10 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Pentium Silver J5040 scores 1,335 in single-core performance and 3,211 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 2,070 for overall performance, 3,956 for productivity performance, 4,169 for creator performance, 3,091 for engineering performance and 4,808 for gaming performance. Its multi-core throughput works out to 803 per core, 803 per thread and 321 per watt. Its computed efficiency index is 655. Its performance index is 26, so its overall performance is 74% 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 Pentium Silver J5040 scores 12,895 in integer math, 6,783 in floating-point math, 45,870 in compression, 1,936 in cryptography, 209 in physics simulation, 1,338 in vector SIMD, 7 in the prime sieve and 5,684 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 78% below in integer math, 85% below in floating-point math, 80% below in compression, 83% below in cryptography, 81% below in physics simulation, 91% below in vector SIMD, 90% below in the prime sieve and 75% 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 Pentium Silver J5040 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 2.00 GHz and boosts up to 3.20 GHz.

The Intel Pentium Silver J5040 is a laptop processor, belongs to the Intel Pentium Silver family, uses the Gemini Lake architecture, carries the codename Gemini Lake Refresh and is manufactured on a 14 nm process. It launched in Oct 2019.

The Intel Pentium Silver J5040 has 224 KB of L1 cache, 4 MB of L2 cache and 4 MB of L3 cache. That adds up to about 8.2 MB of cache, or 2.06 MB per core.

The Intel Pentium Silver J5040 has a 3-level cache hierarchy: L1 at 224 KB, L2 at 4 MB and L3 at 4 MB. L2 is the largest level and makes up about 49% of the cache listed here.

The Intel Pentium Silver J5040 supports DDR4, LPDDR4 memory, addresses up to 8 GB of memory, uses 2 memory channels and runs memory at up to 2,400 MT/s. It does not support DDR5 memory.

The Intel Pentium Silver J5040 includes integrated graphics (Intel UHD Graphics 605) and clocks the graphics up to 0.80 GHz.

The Intel Pentium Silver J5040 uses the FCBGA1090 socket, supports PCI Express 2.0 and provides up to 6 PCIe lanes.
