But if you go back in time, you’ll see the PCs using DDR2 RAM along with the Core 2 Duo. With the introduction of the i5 processor, the RAM standard in PCs has shifted to DDR3. This eventually favors the i5 processor over the Core 2 Duo. Thus, the performance of the latter is more satisfying than the former. Note that LGA 775 are older sockets than LGA 1150 or 1155. But the Core 2 Duo processor comes with FCLGA 775. Regarding the sockets in the given processors, the ones found in the Core i5 second-generation processors are FCLGA 1150 or 1155. So, if performance is the priority, then the latter can’t beat the former. Intel Core i5 provides up to and over 400 percent better performance than the Core 2 Duo processor. Now, you can expect i5 to have better features than the Core 2 Duo.

It means that the former is a newer processor than the latter. The Core i5 processor was released in 2009, while the Core 2 Duo was introduced in 2006. Plus, i5 advanced FCLGA sockets and more cache than the Core 2 Duo processor. Also, the i5 comes with an integrated GPU, while the Core 2 Duo doesn’t. The main difference between Intel Core 2 Duo and i5 is that the Intel Core i5 is technologically more advanced.

Up to and over 400 percent more than Core 2 Duo Does RAM Size Affect The Processor’s Performance? Is It Possible To Replace Core 2 Duo With Core 2 Quad?
