Intel® Core™ i3-8350K

The Intel Core i3-8350K is a desktop processor with 4 cores and 4 threads, built on the Coffee Lake architecture (14 nm process). It launched in Oct 2017. 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 91 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i3-8350K scores 2,450 in single-core performance and 6,916 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 4,116 for overall performance, 7,925 for productivity performance, 8,214 for creator performance, 6,657 for engineering performance and 9,079 for gaming performance. Its multi-core throughput works out to 1,729 per core, 1,729 per thread and 76 per watt. Its computed efficiency index is 432. Its performance index is 51, so its overall performance is 49% 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 i3-8350K scores 18,030 in integer math, 15,436 in floating-point math, 91,144 in compression, 2,050 in cryptography, 566 in physics simulation, 8,109 in vector SIMD, 40 in the prime sieve and 11,241 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 69% below in integer math, 66% below in floating-point math, 60% below in compression, 82% below in cryptography, 48% below in physics simulation, 48% below in vector SIMD, 40% below in the prime sieve and 50% 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 i3-8350K 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 4.00 GHz.

The Intel Core i3-8350K is a desktop processor, belongs to the Intel Core i3 family, uses the Coffee Lake architecture, carries the codename Coffee Lake and is manufactured on a 14 nm process. It launched in Oct 2017.

The Intel Core i3-8350K has 256 KB of L1 cache, 1 MB of L2 cache and 8 MB of L3 cache. That adds up to about 9.3 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i3-8350K has a 3-level cache hierarchy: L1 at 256 KB, L2 at 1 MB and L3 at 8 MB. L3 is the largest level and makes up about 86% of the cache listed here.

The Intel Core i3-8350K 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 Core i3-8350K includes integrated graphics (Intel UHD Graphics 630) and clocks the graphics up to 1.15 GHz.

The Intel Core i3-8350K uses the FCLGA1151 socket, supports PCI Express 3.0 and provides up to 16 PCIe lanes.

The Intel Core i3-8350K has a rated TDP of 91 W.
