Intel Core i5-540UM vs Intel Core i5-14400T

In this CPU comparison, we compare the Intel Core i5-540UM and the Intel Core i5-14400T and use benchmarks to check which processor is faster.

We compare the Intel Core i5-540UM 2 core processor released in Q2/2010 with the Intel Core i5-14400T which has 10 CPU cores and was introduced in Q1/2024.

The Intel Core i5-540UM is a 2 core processor with a clock frequency of 1.20 GHz (2.00 GHz). The processor can compute 4 threads at the same time. The Intel Core i5-14400T clocks with 1.50 GHz (4.50 GHz), has 10 CPU cores and can calculate 16 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 8 GB of memory in a maximum of 2 memory channels is supported by the Intel Core i5-540UM, while the Intel Core i5-14400T supports a maximum of 192 GB of memory with a maximum memory bandwidth of 76.8 GB/s enabled.

The Intel Core i5-540UM has a TDP of 18 W. The TDP of the Intel Core i5-14400T is 35 W. System integrators use the TDP of the processor as a guide when dimensioning the cooling solution.

The Intel Core i5-540UM has 3.00 MB cache and is manufactured in 32 nm. The cache of Intel Core i5-14400T is at 29.50 MB. The processor is manufactured in 10 nm.
