Intel Core Ultra 7 155HL vs Intel Core i7-1255UL

In this CPU comparison, we compare the Intel Core Ultra 7 155HL and the Intel Core i7-1255UL and use benchmarks to check which processor is faster.

We compare the Intel Core Ultra 7 155HL 16 core processor released in Q2/2024 with the Intel Core i7-1255UL which has 10 CPU cores and was introduced in Q3/2022.

The Intel Core Ultra 7 155HL is a 16 core processor with a clock frequency of 1.40 GHz (4.80 GHz). The processor can compute 22 threads at the same time. The Intel Core i7-1255UL clocks with 2.60 GHz (4.70 GHz), has 10 CPU cores and can calculate 12 threads in parallel.

The performance values of the processor's AI unit. The isolated NPU performance is specified here, the total AI performance (NPU+CPU+iGPU) can be higher. Processors with support for artificial intelligence (AI) and machine learning (ML) can process many calculations, especially audio, image and video processing, much faster than classic processors.

Graphics (iGPU) integrated into the processor not only enable image output without having to rely on a dedicated graphics solution, but can also efficiently accelerate video playback.

A photo or video codec that is accelerated in hardware can greatly accelerate the working speed of a processor and extend the battery life of notebooks or smartphones when playing videos.

Up to 96 GB of memory in a maximum of 2 memory channels is supported by the Intel Core Ultra 7 155HL, while the Intel Core i7-1255UL supports a maximum of 64 GB of memory with a maximum memory bandwidth of 76.8 GB/s enabled.

The Intel Core Ultra 7 155HL has a TDP of 45 W. The TDP of the Intel Core i7-1255UL is 15 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Core Ultra 7 155HL has 42.00 MB cache and is manufactured in 7 nm. The cache of Intel Core i7-1255UL is at 18.50 MB. The processor is manufactured in 10 nm.
