The Lineup

Intel will initially launch quad-core SKUs on the desktop. Ivy Bridge will be branded as Intel's 3rd generation Core microarchitecture and use model numbers below 3800. The 3800 - 3900 series are reserved for Sandy Bridge E for the time being, while the 2000 series refers to last year's Sandy Bridge parts. Just like we saw with Sandy Bridge, Ivy will be available in fully unlocked (K-series), partially unlocked (any part with Turbo support) and fully locked (anything without Turbo support) SKUs.

What we know about the lineup today is summarized in the table below:

Processor Core Clock Cores / Threads L3 Cache Max Turbo Intel HD Graphics TDP Price
Intel Core i7 3960X 3.3GHz 6 / 12 15MB 3.9GHz N/A 130W $990
Intel Core i7 3930K 3.2GHz 6 / 12 12MB 3.8GHz N/A 130W $555
Intel Core i7 3820 3.6GHz 4 / 8 10MB 3.9GHz N/A 130W $285
Intel Core i7 3770K 3.5GHz 4 / 8 8MB 3.9GHz 4000 77W $332 est
Intel Core i7 3770 3.4GHz 4 / 8 8MB 3.9GHz 4000 77W $294 est
Intel Core i5 3570K 3.4GHz 4 / 4 6MB 3.8GHz 4000 77W TBD
Intel Core i5 3570 3.4GHz 4 / 4 6MB 3.8GHz 2500 77W TBD
Intel Core i5 3550 3.3GHz 4 / 4 6MB 3.7GHz 2500 77W TBD
Intel Core i5 3470 3.2GHz 4 / 4 6MB 3.6GHz 2500 77W TBD
Intel Core i5 3450 3.1GHz 4 / 4 6MB 3.5GHz 2500 77W TBD
Intel Core i5 3330 3.0GHz 4 / 4 6MB 3.2GHz 2500 77W TBD
Intel Core i7 2700K 3.5GHz 4 / 8 8MB 3.9GHz 3000 95W $332
Intel Core i7 2600K 3.4GHz 4 / 8 8MB 3.8GHz 3000 95W $317
Intel Core i7 2600 3.4GHz 4 / 8 8MB 3.8GHz 2000 95W $294
Intel Core i5 2500K 3.3GHz 4 / 4 6MB 3.7GHz 3000 95W $216
Intel Core i5 2500 3.3GHz 4 / 4 6MB 3.7GHz 2000 95W $205

Unlike the initial Sandy Bridge launch, both fully and partially unlocked Ivy Bridge parts will ship with Intel HD 4000 graphics - although that's still reserved for the high-end on the desktop. I am also seeing movement towards removing core-count restrictions on turbo frequencies. Today max turbo is defined in most cases by the highest frequency you can reach with only one core active. I would not be surprised to see Intel eventually move to a setup where max turbo can be reached regardless of number of active cores and just base it on current power consumption and thermal conditions.

Chipset Support

Ivy Bridge uses the same LGA-1155 socket as Sandy Bridge. Provided there's BIOS/UEFI support from your board maker, you can use Ivy Bridge CPUs in older 6-series motherboards. Doing so won't give you access to some of the newer 7-series chipset features like PCIe Gen 3 (some 6-series boards are claiming 3.0 support), native USB 3.0 (many 6-series boards have 3rd party USB 3.0 controllers) and Intel's Rapid Start Technology.

The big change this year is that all 7-series chipsets support processor graphics, while last year Intel had the silly P vs. H split until Z68 arrived and simplified everything.

    CPU perf pretty much as expected,GPU perf somewhat dissapointing ,i thought they'll at least aim to match Llano but i guess it is ok for 1MP laptops screens if mobile parts perform close enough (and a couple of big ifs when it comes to image quality and drivers).
    Any opinions yet about QuickSync encoding quality?

    And we should remark that's comparing 2600 with 3700 which have different cpu too.
    Other benchmarks had significantly better results on 3700 than 2600.

    So Anand, how you know that difference is not attributable to the CPU and not to some gpu improvement?

    You are not being serious, are you? The CPU gets 10% in CPU sensitive benchmarks and GPU gained 40-60%. Even taking out 10%, its still 30-50%, which btw isn't true as games aren't very sensitive to CPU changes as applications do. Reply

    Look at crisys or metro benchmarks and tell me where you find that improvement, at least more than what you find in cpu difference. Reply

    I've tried it on some HD clips at a local TV station and on a big screen it really sucked.It's way behind AMD.We used aHP EliteBook 8460P laptop. Reply

    At least AMD's products are HD capable. Reply

    My 5 year old laptop with a shared ram gpu is "HD capable". GTFO noob. Reply

    Billions in R&D, double the MSRP, half the power and yet it still can't play Crysis better than Llano, which will be replaced by Trinity in a few weeks. What a crying shame. Reply

    Not playing Crysis sounds like a good thing to me. Reply

    Source or gtfo. Apple got the stock HD 3000, why would this be different? Reply
