Intel® Xeon™ W-11955M

The Intel Xeon W-11955M is a laptop processor with 8 cores and 16 threads, built on the Tiger Lake architecture. It launched in Apr 2021. Clocks run from 2.6 GHz base to 5.0 GHz boost. A 24-MB L3 cache backs the cores (4.3 MB per core). Maximum addressable memory is 128 GB. It uses the FCBGA1787 socket. Notable platform capabilities: Gaussian Neural Accelerator, AVX-512, Extended Page Tables (EPT), Control-flow Enforcement (CET).

The Intel Xeon W-11955M scores 3,169 in single-core performance and 21,314 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,219 for overall performance, 18,291 for productivity performance, 17,427 for creator performance, 21,847 for engineering performance and 14,836 for gaming performance. Its multi-core throughput works out to 2,664 per core and 1,332 per thread. Its performance index is 102, so its overall performance is 2% 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 Xeon W-11955M scores 75,637 in integer math, 44,678 in floating-point math, 249,481 in compression, 12,958 in cryptography, 1,036 in physics simulation, 16,631 in vector SIMD, 95 in the prime sieve and 30,271 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 28% above in integer math, 3% below in floating-point math, 9% above in compression, 13% above in cryptography, 5% below in physics simulation, 7% above in vector SIMD, 42% above in the prime sieve and 34% 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 Xeon W-11955M has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 2.60 GHz and boosts up to 5.00 GHz.

The Intel Xeon W-11955M is a laptop processor, belongs to the Intel Xeon W family, uses the Tiger Lake architecture, carries the codename Tiger Lake and is manufactured on a 10 nm process. It launched in Apr 2021.

The Intel Xeon W-11955M has 640 KB of L1 cache, 10 MB of L2 cache and 24 MB of L3 cache. That adds up to about 34.6 MB of cache, or 4.33 MB per core. Each core has 1.25 MB of private L2 cache.

The Intel Xeon W-11955M has a 3-level cache hierarchy: L1 at 640 KB, L2 at 10 MB and L3 at 24 MB. L3 is the largest level and makes up about 69% of the cache listed here.
