AMD Unsure About 20nm Time Frame

May use current process that little bit longer.

The manufacturing process and technology of microprocessors is one that is ever advancing, with chips becoming smaller, more power and more energy efficient in the process. But it's really not as simple as it sounds to keep up with the pace of technological advancement, even for those that do it for a living. It makes sense that a proven node can mean lower costs and AMD thinks so too, stating that they expect current and each following generation of process technologies to be utilized for longer periods of time.

With companies like TSMC and Global Foundries already working on 14nm devices for mobile applications, due to their low power consumption performance, AMD looks set to run on 28nm until well into 2014. This does of course make some sense, as AMD has no interest or serious investment in the mobile market, its bread and butter is in servers and desktops. So it seems 28nm will do for the next gen FX and Opteron series of products as AMD seeks to extend the lifetime of nodes, as this will no doubt reduce costs greatly and ensure greater availability.

It's no surprise that AMD is looking for ways to be more competitive in the market and while some may think not leaping on the latest manufacturing techniques is suicide, there is a lot of merit to their decisions. New nodes for manufacturing are expensive and require a lot of time and investment to advance, sticking with the current model longer means you can focus on reducing cost and build new generations of chips by re-using current technology in different configurations.

It's a tough time for AMD and while Intel, Samsung and other fabrication plants hammer forward with nothing but the latest manufacturing techniques, it will be interesting to see if AMD's technique will prove successful in this tortoise and the hare struggle.
