Intel Core i3-3227U vs Intel Pentium E5400

Core i3-3227U vs Pentium E5400 specs and performance

In our benchmarks, the Core i3-3227U beats the Pentium E5400 in overall performance. Despite this, the Pentium E5400 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores but the Core i3-3227U has more threads. Our comparison shows that the Pentium E5400 has a slightly higher clock speed compared to the Core i3-3227U. A Core i3-3227U CPU outputs less heat than a Pentium E5400 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Core i3-3227U has more threads than cores. Each physical core is split into multiple threads.
