Intel® Core™ Ultra 9 290K Plus

The Intel Core Ultra 9 290K Plus is a mobile processor with a hybrid 24-core layout (8 performance cores + 16 efficiency cores) and 24 threads, built on the Arrow Lake architecture. It launched in Q1 2026. Boost clock reaches 5.5 GHz. A 36-MB L3 cache backs the cores (3.3 MB per core). Maximum addressable memory is 256 GB. It uses the FCBGA2114 socket.

The Intel Core Ultra 9 290K Plus scores 4,823 in single-core performance and 60,860 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,133 for overall performance, 46,311 for productivity performance, 42,154 for creator performance, 77,597 for engineering performance and 29,684 for gaming performance. Its multi-core throughput works out to 2,536 per core and 2,536 per thread. Its performance index is 212, so its overall performance is 112% 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 Ultra 9 290K Plus scores 166,194 in integer math, 214,760 in floating-point math, 698,346 in compression, 52,563 in cryptography, 3,315 in physics simulation, 52,338 in vector SIMD, 503 in the prime sieve and 79,744 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 182% above in integer math, 368% above in floating-point math, 206% above in compression, 358% above in cryptography, 204% above in physics simulation, 237% above in vector SIMD, 651% above in the prime sieve and 252% 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 Ultra 9 290K Plus has 24 physical cores and runs 24 logical threads. It uses a hybrid layout of 8 performance cores and 16 efficiency cores. It does not support simultaneous multithreading, so its thread count equals its core count. It boosts up to 5.50 GHz.

The Intel Core Ultra 9 290K Plus is a mobile processor, belongs to the Intel Core Ultra 9 family and uses the Arrow Lake architecture. It launched in Q1 2026.

The Intel Core Ultra 9 290K Plus has 2.38 MB of L1 cache, 40 MB of L2 cache and 36 MB of L3 cache. That adds up to about 78.4 MB of cache, or 3.27 MB per core.

The Intel Core Ultra 9 290K Plus has a 3-level cache hierarchy: L1 at 2.4 MB, L2 at 40 MB and L3 at 36 MB. L2 is the largest level and makes up about 51% of the cache listed here.

The Intel Core Ultra 9 290K Plus addresses up to 256 GB of memory and uses 2 memory channels. It does not support ECC memory.

The Intel Core Ultra 9 290K Plus uses the FCBGA2114 socket and provides up to 24 PCIe lanes.
