Core i5-5200U vs Pentium G645 comparison

Our benchmark analysis concludes that the Core i5-5200U performs better than the Pentium G645. Despite this, the Pentium G645 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count but the Core i5-5200U has more threads. With our hardware info, we find that the Pentium G645 has a slightly higher clock speed than the Core i5-5200U. A Core i5-5200U CPU outputs less heat than a Pentium G645 CPU because of its significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Pentium G645 has significantly more L2 cache when compared to the Core i5-5200U. However, both these chips have the same amount of L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. Indeed, the Core i5-5200U has more threads than cores. Each physical core is split into multiple threads.
