Chipmaker, Advanced Micro Devices, has launched its first 45nm ‘Shanghai’ Opteron chips for servers and workstations.

It also has a forthcoming range of desktop processors built on 45nm technology codenamed "Deneb". Both of these ranges are constructed using a process called "immersion lithography". AMD claim that this fabrication technique will lead to ‘dramatic performance and performance-per-watt gains.’

The new Opterons will have an increased clock speed due to this fabrication process; rising from 2.3 GHz with the current Barcelona-cored Opterons, to 2.7 GHz with the Shanghai-cored chips. The current Phenom range, which run at up to 2.6GHz, may also benefit from this upward-clocking in their next incarnation.

The new Shanghai-cores also benefit from increased cache-size, as well as from HyperTransport 3.0, which increases bandwidth considerably. Let’s hope they vastly outperform the Intel competition as well as the previous/current Phenom CPUs, or AMD is going to have a hard time on its hands and will probably end up cutting retail prices to offer a cheaper though lesser alternative to the Intel  developments.

AMD also plan to introduce a new six-cored range of chips called "Istanbul" sometime next year (2009). As for Deneb; AMD will probably be launching them before the end of 2008.

The Question is can AMD ever get ahead of Intel again? Can they even catch up; and if so is this their chance? What’s your opinion?
