I was all set to purchase an i5 2500k Sandy Bridge CPU. Now Ivy Bridge chips have been released, and I am confused. Should I still buy the i5 2500k Sandy Bridge CPU or should I buy a new Ivy Bridge chip? If you suggest an Ivy Bridge chip, which one do you recommend and why? Could you please provide a Newegg link to the one you recommend so that I can make sure I am purchasing the right chip.
But, is there any reason not to buy an Ivy Bridge CPU now since it is already out?
Any reason? Price comparison is pretty much it. Like others have said, Ivy and Sandy are pretty much same architecture, just die shrink and more die space for integrated graphics. IPC's are extremely similar but the edge goes to Ivy. And OCing is pretty similar but the edge goes to sandy. So a 2500K at 4.7ghz will be equivalent to a 3570K at 4.5ghz. So indeed you can oc a sandy "better" but you will have to to be even. Although you should realize that all this is like cutting hairs, I doubt you'll even notice the difference unless you're really into benchmarks and studying performance numbers. So if price is comparable, which I heard it is, and you're not upgrading from sandy I would get the ivy chip.
It depends on your needs. Sandybridge will overclock higher on air, but if you're not planning on overclocking, IvyBridge has lower power consumption, PCIe 3.0, SSD caching (intel rapid response) and from what I can tell they are priced marginally higher than their Sandybridge counter parts.
It really all comes down to what you intend to do with it.
Some people will warn that Ivybridge is a new technology, and you may want to wait a few months for them to work out any issues with it.
I think for the average PC buyer, Ivybridge with it's lower power requirements at stock is the way to go. As an enthusiast builder, it's a tougher decision.
Personally I'm waiting to see if there are any price drops on SB in the coming weeks before making a decision.
