Intel® Core™ i5-8500B

The Intel Core i5-8500B is a laptop processor with 6 cores and 6 threads, built on the Coffee Lake architecture (14 nm process). It launched in Apr 2018. Clocks run from 3.0 GHz base to 4.1 GHz boost. A 9-MB L3 cache backs the cores (1.7 MB per core). It addresses DDR4 memory up to 64 GB across 2 channels. The chip drops into the FCBGA1440 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 65 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i5-8500B scores 2,524 in single-core performance and 8,770 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,705 for overall performance, 9,234 for productivity performance, 9,367 for creator performance, 8,715 for engineering performance and 9,765 for gaming performance. Its multi-core throughput works out to 1,462 per core, 1,462 per thread and 135 per watt. Its computed efficiency index is 584. Its performance index is 58, so its overall performance is 42% 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 i5-8500B scores 25,745 in integer math, 19,450 in floating-point math, 129,890 in compression, 2,872 in cryptography, 647 in physics simulation, 7,585 in vector SIMD, 36 in the prime sieve and 14,974 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 56% below in integer math, 58% below in floating-point math, 43% below in compression, 75% below in cryptography, 41% below in physics simulation, 51% below in vector SIMD, 46% below in the prime sieve and 34% 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 i5-8500B has 6 physical cores and runs 6 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 4.10 GHz.

The Intel Core i5-8500B is a laptop processor, belongs to the Intel Core i5 family, uses the Coffee Lake architecture, carries the codename Coffee Lake and is manufactured on a 14 nm process. It launched in Apr 2018.

The Intel Core i5-8500B has 256 KB of L1 cache, 1 MB of L2 cache and 9 MB of L3 cache. That adds up to about 10.3 MB of cache, or 1.71 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i5-8500B has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 9 MB. L3 is the largest level and makes up about 88% of the cache listed here.

The Intel Core i5-8500B supports DDR4 memory, addresses up to 64 GB of memory, uses 2 memory channels, runs memory at up to 2,666 MT/s and delivers up to 42.7 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Core i5-8500B includes integrated graphics (Intel UHD Graphics 630) and clocks the graphics up to 1.10 GHz.

The Intel Core i5-8500B uses the FCBGA1440 socket, supports PCI Express 3.0 and provides up to 16 PCIe lanes.

The Intel Core i5-8500B has a rated TDP of 65 W.
