AMD Shanghai hopes to erase bad memories of Barcelona

AMD has proven to be a tough opponent for Intel in the server processor marketplace. AMD said that its latest architecture dubbed Shanghai is now ready to go. Shanghai parts are quad-core processors that are targeted at the server market.

Shanghai is also AMD's first 45-nanometer processor. AMD's last big architecture aimed at the server marketplace was the Barcelona processor that ran into significant problems in the market. One of the biggest issues with Barcelona was that the processors were delayed for eight months after their introduction.

Once the processors were finally shipped and available, AMD had issues with the performance of the parts and the CPUs suffered from other glitches. AMD promises that Shanghai will not be another Barcelona.

Pat Patla, AMD server and workstation business general manager, told CNET News, "We had some mis-starts in getting Barcelona to market and wanted to bring as much velocity to Shanghai as possible. Learn from our mistakes and, as a company, never do that again."

To help ensure that Shanghai succeeds and offer users a better experience than Barcelona, AMD put one engineer in charge of the entire Shanghai project. Patla continued saying, "the product that we put in the hands of our partners is going to be of substantial stability so they can do lots of early validation."

To improve the performance of Shanghai over Barcelona, AMD is counting on several factors. First is the move from the 65nm process of Barcelona to the 45nm process used in Shanghai. This will allow for more efficiency and better performance than Barcelona.

AMD is also moving the cache memory from 2MB to 6MB to improve performance and it says that instructions per clock cycle will be increased as well. Shanghai will also utilize AMD's HyperTransport 3, which AMD expects to be validated in Q1 2009. A 45nm desktop Shanghai part will be offered in Q1 2009 according to CNET News.

Too little too late

Is this chip even as fast as the Core2 preformance per watt? Let alone Intels next up.

Yes, it is as fast as Core2 quad per clock and possibly more efficient per watt in some instances. From what I have seen these chips will be equal to Core2 chips in performance.

It is not however as fast as the Intel i7core Nehalem processors on a per clock basis.

The big question is when multiple sockets are involved, how much faster is this system going to perform than a Intel based system. AMD's shanghai may be fast superior in certain applications involving multiple sockets and well threaded applications.

Performance per watt is fine for a laptop, but on the desktop "performance per $" is the most important thing for me.
Also, I like a toasty desktop to help heat my apartment ;-)

Ill trade you my 3Ghz Pentium 4 with HD2600XT lol. It makes a nice little space heater :)
