The 7 Series Chipset & USB 3.0
The platform story around Ivy Bridge is far better than it was when Sandy Bridge launched. There are a ton of chipsets, but the delineation makes sense this time. All chipsets support Ivy's processor graphics, however only the Z75/Z77 support CPU overclocking. The good news for current 6-series/Sandy Bridge owners is, with BIOS support, your platforms can support Ivy Bridge as well—making for a better upgrade path down the road.

The new 7-series platform features PCIe 3.0 support, but only when used with an Ivy Bridge CPU, and only on the lanes that branch off of the CPU itself—the PCH lanes are still PCIe 2.0. Ivy's processor graphics, when combined with a 7-series chipset, also enables support for three independent displays (up from 2 with Sandy Bridge/6-series). Other than those two items, the only remaining feature is USB 3.0 support. Intel's 7-series PCH finally has native support for up to 4 USB 3.0 ports.
Performance of Intel's USB 3.0 controller is very good as you'll see in our upcoming Ivy Bridge motherboard roundup.
Intel's 7-series chipset does support Thunderbolt when paired with an external Cactus Ridge Thunderbolt controller, however the Thunderbolt for PCs launch has been pushed back to late May so we'll have to wait a bit before diving into that.
While most enthusiasts will focus on Z77, you can give up SSD caching, some flexibility on the PCIe side (and Thunderbolt support) and go for Intel's Z75 chipset. The chipset itself isn't much cheaper, but boards built around it will likely target lower price points and be lighter on features.

.... and in this multivariate comparison you choose to ignore the superior battery life which makes Llano a serious competitor in the mobile space.midn8t - Thursday, June 28, 2012 - link
this the frames pre secound for CPU, you cant really figure out well when gamming its all mostly based around what ever video card they used, in this artical so I would have to guess that they might have used diffrent GPU video card in each system.obivuously they cant use same motherboard for amd vs intel
Also I find it wired that other reciews have Rated the phenom II x6 lower in preformance then the FX chip makes it wired how these review claims that the phenom II which is lower grade CPU is more powerfull then the top of the line AMD product out.

A huge chunk of text is spent explaining how while its a step in the right direction, they need to do more on the GPU side of the equation. Take off your strangely coloured glasses.wingless - Monday, April 23, 2012 - link
EDIT: I'M NOT KIDDING. I bought my 2600K the Friday before last for $199 and paired it with an ASUS P8Z77-V PRO. Ivy Bridge is simply too hot and lacks OC performance.I overclock so I WILL be keeping my 2600K for the foreseeable future!

So HD4000 igp is weaker than last gen Brazos ?? Based on the leaked Trinity benchmarks, Trinity blows any Intel igp into the weeds, never mind the ( already 1.5 yr old ) Brazos, which is 'only' 5% faster.fredisdead - Sunday, April 29, 2012 - link

I'll keep my 2500k @ 4.6ghzNot kidding

And I'll keep mine at 4.9GHz.But that's just because I'll be waiting for the tock, not the tick.
I will however be getting a Ivy Bridge Laptop soon.

Me too, the 2500K is a great chip. Especially with watercooling.Ratman6161 - Monday, April 23, 2012 - link
For anyone like me who already has a Sandy Bridge quad core (mine's a 2600K) it wouldn't make a lot of sense to "upgrade" to an Ivy bridge. But for those with older systems looking to upgrade, these actually seem like pretty good deals. @ $313 the 3770K is cheaper than the 2700K and cheaper than the typical price on a 2600K (unless like me you are lucky enough to live near a Micro Center).As to those complaining about graphics, come on. Will anyone who really cares a lot about graphics, particularly gaming, be using the on board graphics anyway?
