To be quick about it, the Pentium is basically identical to the i3 but with certain features disabled to differentiate it from the i3 and make it fit the price range of a low-end model.įor starters, the Pentium only has 3MB of 元 cache memory while the i3 has 4MB. But with the introduction of the Pentium G6950 and the Core i3 5xxx series, which are both Clarkdales, the need to identify the differences between them arises again. The Pentium is probably the most popular line of Intel processors but it has been cast of the limelight due to the appearance of the newer Core line.
