Intel® Core™ Ultra 7 256V

The Intel Core Ultra 7 256V is a laptop processor with a hybrid 8-core layout (4 performance cores + 4 efficiency cores) and 8 threads, built on the Lunar Lake architecture (Compute Tile 's N3B process). It launched in Jul 2024. Clocks run from 2.2 GHz base to 4.8 GHz boost. A 12-MB L3 cache backs the cores (3.4 MB per core). It addresses LPDDR5X memory up to 16 GB across 2 channels. The chip drops into the FCBGA2833 socket and exposes PCIe 5.0 (8 lanes). Rated TDP is 17 W. Notable platform capabilities: Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Core Ultra 7 256V scores 4,023 in single-core performance and 19,568 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,873 for overall performance, 18,351 for productivity performance, 18,004 for creator performance, 20,057 for engineering performance and 16,961 for gaming performance. Its multi-core throughput works out to 2,446 per core, 2,446 per thread and 1,151 per watt. Its computed efficiency index is 2,152. Its performance index is 110, so its overall performance is 10% 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 7 256V scores 43,245 in integer math, 58,441 in floating-point math, 184,498 in compression, 13,963 in cryptography, 1,590 in physics simulation, 15,613 in vector SIMD, 192 in the prime sieve and 22,435 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 27% below in integer math, 27% above in floating-point math, 19% below in compression, 22% above in cryptography, 46% above in physics simulation, 1% above in vector SIMD, 187% above in the prime sieve and 1% 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 Ultra 7 256V has 8 physical cores and runs 8 logical threads. It uses a hybrid layout of 4 performance cores and 4 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 4.80 GHz.

The Intel Core Ultra 7 256V is a laptop processor, belongs to the Intel Core Ultra 7 family, uses the Lunar Lake architecture, carries the codename Lunar Lake and is manufactured on a Compute Tile 's N3B process. It launched in Jul 2024.

The Intel Core Ultra 7 256V has 832 KB of L1 cache, 14 MB of L2 cache and 12 MB of L3 cache. That adds up to about 26.8 MB of cache, or 3.35 MB per core.

The Intel Core Ultra 7 256V has a 3-level cache hierarchy: L1 at 832 KB, L2 at 14 MB and L3 at 12 MB. L2 is the largest level and makes up about 52% of the cache listed here.

The Intel Core Ultra 7 256V supports LPDDR5X memory, addresses up to 16 GB of memory, uses 2 memory channels and runs memory at up to 8,533 MT/s. It does not support DDR5 and DDR4 memory.
