Intel® Core™ i9-9900T

The Intel Core i9-9900T is a desktop processor with 8 cores and 16 threads, built on the Coffee Lake architecture (14 nm process). It launched in Apr 2019. Clocks run from 2.1 GHz base to 4.4 GHz boost. A 16-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1151 socket and exposes PCIe 3.0 (16 lanes). Rated TDP is 35 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i9-9900T scores 2,453 in single-core performance and 13,044 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 5,657 for overall performance, 11,913 for productivity performance, 11,590 for creator performance, 13,370 for engineering performance and 10,620 for gaming performance. Its multi-core throughput works out to 1,631 per core, 815 per thread and 373 per watt. Its computed efficiency index is 956. Its performance index is 70, so its overall performance is 30% 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 i9-9900T scores 49,181 in integer math, 30,273 in floating-point math, 180,697 in compression, 4,575 in cryptography, 782 in physics simulation, 11,950 in vector SIMD, 39 in the prime sieve and 24,326 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 16% below in integer math, 34% below in floating-point math, 21% below in compression, 60% below in cryptography, 28% below in physics simulation, 23% below in vector SIMD, 42% below in the prime sieve and 7% 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 Core i9-9900T has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 4.40 GHz.

The Intel Core i9-9900T is a desktop processor, belongs to the Intel Core i9 family, uses the Coffee Lake architecture, carries the codename Coffee Lake and is manufactured on a 14 nm process. It launched in Apr 2019.

The Intel Core i9-9900T has 512 KB of L1 cache, 2 MB of L2 cache and 16 MB of L3 cache. That adds up to about 18.5 MB of cache, or 2.31 MB per core. Each core has 256 KB of private L2 cache.

The Intel Core i9-9900T has a 3-level cache hierarchy: L1 at 512 KB, L2 at 2 MB and L3 at 16 MB. L3 is the largest level and makes up about 86% of the cache listed here.
