Intel’s Ivy Bridge CPU lineup
Intel has been busy as of late, with its new Sandy Bridge Extreme LGA-2011 platform launched two weeks ago, and the i7 Core 3960X taking the crown from the previous generation Core i7 980X as the fastest desktop processor available. The result was a foregone conclusion, given AMD’s less than impressive top-of-the-line eight core “Bulldozer” FX-8150 performance when pitted against what are arguably two of Intel’s best products in recent years — the i5 Core 2500K and i7 Core 2600K.
With the Sandy Bridge Extreme launch out of the way, attention has now turned to the upcoming 22nm Ivy Bridge line-up, with full details of the entire i5 and i7 model lineup recently surfacing at CPU World.
Eleven new models are listed, covering the i5 and i7 range for mobile and desktop products. According to the site, the Ivy Bridge Core i7 family will feature 77, 65 and 45 Watt power envelopes, which correspond to suffix/”K”, “S” and “T” processor numbers respectively. These are detailed in the charts below:
If the information above is correct, then it appears that most of the Ivy Bridge i5 processors will continue on from Sandy Bridge offering four physical cores, 6MB of L3 cache and no hyper-threading, except for the i5 3470T which is a dual core unit with two hyper-threaded cores.
Moving on to the i7 range, it appears they will continue in much the same way at their Sandy Bridge counterparts, running four physical cores with hyper-threading support, and 2MB more cache available. The new range topping Ivy Bridge part will launch as the i7 3770K, fully unlocked with a 3.5GHz clock speed, where as the “non-K” designated i7 3770 drops down 100MHz to 3.4GHz.
Therefore, in total consumers should see two unlocked, three mainstream, three mid-power level processors and three low power models which presumably will find their way into notebooks on the market once released — with current estimates hinting at a launch date around April 2012.
Five years ago Intel announced its ambitious tick-tock release cadence. We were doubtful that Intel could pull off such an aggressive schedule but with the exception of missing a few months here or there tick-tock has been a success. On years marked by a tick Intel introduces a new manufacturing process, while tock years keep manufacturing process the same and introduce a new microprocessor architecture. To date we’ve had three tocks (Conroe, Nehalem, Sandy Bridge) and two ticks (Penryn, Westmere). Sampling by the end of this year and shipping in the first half of next year will be Intel’s third tick: Ivy Bridge.
Ivy Bridge (IVB) is the first chip to use Intel’s 22nm tri-gate transistors, which will help scale frequency and reduce power consumption. As we already mentioned, mobile Ivy Bridge will be the first Intel CPU to bring four cores into a 35W TDP.
At a high level Ivy Bridge looks a lot like Sandy Bridge. It’s still a monolithic die that features an integrated GPU. The entire die is built at 22nm, continuing Intel’s march towards truly addressing integrated graphics performance. Ivy Bridge won’t get rid of the need for a discrete GPU but, like Sandy Bridge, it is a step in the right direction.
Intel hasn’t announced die size but transistor count has increased to approximately 1.4 billion (layout). This is up from 1.16 billion in Sandy Bridge, a 20.7% increase. With perfect scaling a 22nm Sandy Bridge die would be 47.3% the size of a 32nm die. Even with the increase in transistor count, it’s a good bet that Ivy Bridge will be noticeably smaller than Sandy Bridge.
Motherboard & Chipset Support
Ivy Bridge is backwards compatible with existing LGA-1155 motherboards, although there will be a new chipset for Ivy Bridge and new motherboards to enable some features (e.g. PCI Express 3.0, native USB 3.0). The new chipset family falls under the 7-series banner. We’ll see Z77, Z75, H77, Q77, Q75 and B75 available at or around launch.

As I mentioned above, Ivy Bridge finally supports USB 3.0 natively. The consumer 7-series chipsets feature 14 total USB ports, 4 of which are USB 3.0 capable. The CPU itself features 16 PCIe (1×16, 2×8 or 1×8 + 2×4) gen 3 lanes to be used for graphics and/or high performance IO. You will only see Gen 3 speeds on qualified motherboards. It’s technically possible on 6-series motherboards but guaranteed on 7-series motherboards. The Z77 and H77 chipsets will support Intel’s Smart Response Technology (SRT, aka SSD caching) which is a Z68 exclusive today.
SATA and chipset-attached PCIe slots haven’t changed. Overclocking is supported on all Z-chipsets, while the H-chipset doesn’t. All chipsets support Intel’s HD Graphics, which is a departure from the Sandy Bridge mess where P67 didn’t.
