The transition from DDR2 to DDR3 memory will reach a significant milestone in Q2 2010, as that's when research firm iSupply expects DDR3 shipments to surpass those of its predecessor. Q2 is said to see DDR3 account for over half of the global DRAM market, while by the end of 2010, DDR3's stake will grow to 71%.

"DDR3 is 50 percent faster than today's dominant DRAM technology, DDR2, while using about 30 percent less power," said Mike Howard, senior DRAM analyst for iSuppli. "For PC users across the board, this means faster performance. For notebook users, it can result in longer battery life."

Both Intel and AMD have embraced DDR3 with their current desktop offerings, with the former also moving to DDR3 in the server and mobile space. For 2010 AMD is planning on bringing a DDR3-supporting mobile platform and expanding its DDR3 server line.

Despite the obvious trend that favors DDR3, DDR2 memory will have significant volumes throughout 2010, accounting for 15.4% of gigabit-equivalent shipments the fourth quarter.
