Intel® Core™ Ultra 5 245T

The Intel Core Ultra 5 245T is a desktop processor with a hybrid 14-core layout (6 performance cores + 8 efficiency cores) and 14 threads, built on the Arrow Lake architecture (Compute Tile 's N3B process). It launched in Jan 2025. Clocks run from 2.2 GHz base to 5.1 GHz boost. A 24-MB L3 cache backs the cores (3.7 MB per core). It addresses DDR5 memory up to 256 GB across 2 channels. The chip drops into the FCLGA1851 socket and exposes PCIe 5.0 (24 lanes). Rated TDP is 35 W. Notable platform capabilities: Gaussian Neural Accelerator, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 5 245T scores 4,344 in single-core performance and 30,752 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,558 for overall performance, 26,070 for productivity performance, 24,733 for creator performance, 34,404 for engineering performance and 20,720 for gaming performance. Its multi-core throughput works out to 2,197 per core, 2,197 per thread and 879 per watt. Its computed efficiency index is 1,954. Its performance index is 143, so its overall performance is 43% 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 5 245T scores 86,805 in integer math, 105,957 in floating-point math, 276,393 in compression, 23,061 in cryptography, 2,223 in physics simulation, 21,395 in vector SIMD, 318 in the prime sieve and 33,881 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 47% above in integer math, 131% above in floating-point math, 21% above in compression, 101% above in cryptography, 104% above in physics simulation, 38% above in vector SIMD, 375% above in the prime sieve and 50% 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 5 245T has 14 physical cores and runs 14 logical threads. It uses a hybrid layout of 6 performance cores and 8 efficiency cores. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 2.20 GHz and boosts up to 5.10 GHz.

The Intel Core Ultra 5 245T is a desktop processor, belongs to the Intel Core Ultra 5 family, uses the Arrow Lake architecture, carries the codename Arrow Lake and is manufactured on a Compute Tile 's N3B process. It launched in Jan 2025.

The Intel Core Ultra 5 245T has 1.41 MB of L1 cache, 26 MB of L2 cache and 24 MB of L3 cache. That adds up to about 51.4 MB of cache, or 3.67 MB per core.

The Intel Core Ultra 5 245T has a 3-level cache hierarchy: L1 at 1.4 MB, L2 at 26 MB and L3 at 24 MB. L2 is the largest level and makes up about 51% of the cache listed here.

The Intel Core Ultra 5 245T supports DDR5 memory, addresses up to 256 GB of memory and uses 2 memory channels. It does not support DDR4 and LPDDR memory.
