When Geeks Computer Parts lists Intel E4300, E4400, and E4500 within $1 difference in price ($124), I could not help to request the E4500 for a spin. Intel E4500 is with new M0 stepping rather than previous L2 stepping. The new stepping has lower range of CPU voltage (Vcore). Since not many reviews are out with this particular processor, I thought it would be interesting to find out how the new stepping differs from the old.
