|You'll see a good 15% to 20% increase with Sandy Bridge over Nehalem clock for clock in overall generel performance, which may not seem much to the uneducated eye, but anything over 10% is a healthy performance increase. In some areas especially in media transcoding, Sandy Bridge is a whopping to 35% to 40% faster then Nehalem. Of course this all depends upon what you are using your pc for to really notice any diff just like anything else. But all this is nothing new. Whenever Intel or AMD comes out with a new micro-archtechure it's normally 2x faster then its counterpart overall. It's the ongoing continuation of the technical evolutionary process.|
Is it worth upgrading if you already have a Core i7/i5 series or a highend model Core 2 Duo or Quad series? No. Not unless there is a real legit reason for you to have to upgrade soo soon, especially if you own a Core i7/i5 series.
Yes, the 1156 socket is dead. I posted an article about this around this time last year on here. So people that keep up to date with the latest hardware news were already aware of this a long time ago. Intel said they had to come out with a new platform for Sandy Bridge because of the way they moved and added things into the processor that it required a new LGA to support it. Some pc critics seem to dispute this and will say Intel could have used the same platform that Nehalem used with Sandy Bridge especially since ASrock just came out with a 1156 P67 motherboard, which originally were only to support LGA 1155 Sandy Bridge processors. Regardless Intel will not be producing anymore new Nehalem based processors on the LGA 1156 platform.
Personally, if you are in the market for a new intel based pc, i'd wait for Ivy Bridge which will be out by the end of this year. Ivy Bridge brings 22nm technology and DirectX 11 support with it on die, just to name a few things of what it has over Sandy Bridge. Overclock enthusiast will especially be chomping at the bits when Ivy
Bridge is released due to the fact that Ivy Bridge's 22nm will bring a lot more overclocking potential than current 32nm technology.
As for me, my AM2+ system has been doing everything I need it to do. So I'm happy with it. I prob won't consider thinking about building a new system until DDR4 hits the market, which will be some time early in 2012. By then It will prob be time for me to do another build considering this pc will be going on 4 years old by then.
