Intel® Core™ i9-9990XE

The Intel Core i9-9990XE is a desktop processor with 14 cores and 28 threads, built on the Skylake architecture (14 nm process). It launched in Jan 2019. Clocks run from 4.0 GHz base to 5.0 GHz boost. A 19.25-MB L3 cache backs the cores (2.4 MB per core). It supports DDR4 memory. The chip drops into the FCLGA2066 socket and exposes PCIe 3.0 (44 lanes). Rated TDP is 255 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Core i9-9990XE scores 2,970 in single-core performance and 30,162 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,465 for overall performance, 23,763 for productivity performance, 21,935 for creator performance, 33,744 for engineering performance and 16,451 for gaming performance. Its multi-core throughput works out to 2,154 per core, 1,077 per thread and 118 per watt. Its computed efficiency index is 593. Its performance index is 117, so its overall performance is 17% above 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 i9-9990XE scores 109,175 in integer math, 69,540 in floating-point math, 472,546 in compression, 11,214 in cryptography, 1,768 in physics simulation, 31,188 in vector SIMD, 115 in the prime sieve and 62,093 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 85% above in integer math, 52% above in floating-point math, 107% above in compression, 2% below in cryptography, 62% above in physics simulation, 101% above in vector SIMD, 72% above in the prime sieve and 174% 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 i9-9990XE has 14 physical cores and runs 28 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 4.00 GHz and boosts up to 5.00 GHz.

The Intel Core i9-9990XE is a desktop processor, belongs to the Intel Core i9 family, uses the Skylake architecture, carries the codename Skylake and is manufactured on a 14 nm process. It launched in Jan 2019.

The Intel Core i9-9990XE has 896 KB of L1 cache, 14 MB of L2 cache and 19.3 MB of L3 cache. That adds up to about 34.1 MB of cache, or 2.44 MB per core. Each core has 1 MB of private L2 cache.

The Intel Core i9-9990XE has a 3-level cache hierarchy: L1 at 896 KB, L2 at 14 MB and L3 at 19.3 MB. L3 is the largest level and makes up about 56% of the cache listed here.

The Intel Core i9-9990XE supports DDR4 memory, uses 4 memory channels, runs memory at up to 2,666 MT/s and delivers up to 85.3 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Core i9-9990XE does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Core i9-9990XE uses the FCLGA2066 socket, supports PCI Express 3.0 and provides up to 44 PCIe lanes.

The Intel Core i9-9990XE has a rated TDP of 255 W.
