Ivy Bridge mobile CPU lineup revealed

The launch of Ivy Bridge micro-architecture is still a quarter away, but we already have plenty of information on upcoming desktop microprocessors, thanks to a series of leaks of Intel roadmap slides. Not only desktop roadmap has been leaked. VR-Zone published yesterday a few slides, containing release schedule and specifications of Ivy Bridge mobile microprocessors. According to published slides, Intel will launch 3 quad-core CPUs in April, followed by 3 dual-core mainstream models and two ULV processors in May.

Three quad-core SKUs, planned for April of next year, are Core i7-3920XM Extreme Edition with unlocked clock multiplier, Core i7-3820QM and i7-3720QM. Extreme Edition CPU has 8 MB L3 cache and 55 Watt Thermal Design Power, whereas 3820QM and 3720QM have 45 Watt TDP, and 8 MB and 6 MB of last level cache respectively. The quad-cores are clocked from 2.6 to 2.9 GHz, and their maximum Turbo Boost frequency ranges from 3.6 to 3.8 GHz.

Upcoming dual-core mainstream models with 35 Watt TDP are Core i7-3520M, Core i5-3360M and i5-3320M. Core i5 CPUs have 3 MB L3, and Core i7 chip features somewhat larger 4 MB cache. The processors operate from 2.6 to 2.9 GHz, with maximum Turbo frequency reaching 3.6 GHz. These microprocessors will be released in May 2012.

Two other SKUs, that will be available in May 2012, are Ultra-Low Voltage Core i7-3667U and Core i5-3427U. These parts come with 2 CPU cores, and run at 1.8 and 2 GHz, or up to 2.8 GHz and 3.2 GHz in boost mode. Core i7-3667U features 4 MB L3 cache, and Core i5 chip has 3 MB level 3 cache. Both microprocessors boast significantly lower power consumption than mainstream models, 17 Watt for the CPU and on-chip graphics combined.

The full line-up of Ivy Bridge Core i5s and Core i7s will support all advanced technologies, including Hyper-Threading, Turbo Boost, AES and Vpro. The processors will work with DDR3 memory with data rates up to 1600 MHz, and low-voltage DDR3 with data rates up to 1333 MHz. All Core i5 and i7 Ivy Bridge CPUs will incorporate HD 4000 graphics, clocked at 350 MHz on ULV, and 650 MHz on mainstream parts. Maximum frequency of on-chip graphics unit will range from 1150 to 1300 MHz, depending on SKU. ULV parts will be offered in BGA package, Core i7-3920XM will be manufactured in PGA package, and the rest of the chips will be available in both package types.

Performance of Ivy Bridge mobile processors is expected to be higher due to microarchitecture improvements, higher memory bandwidth on dual-core models, more powerful on-chip graphics, and higher clock speeds. We compiled difference between main features of Sandy Bridge and Ivy Bridge CPUs in the table below:

OK, now we know the main specs...
Next, will be getting a test sample, ideally inside a working laptop or Ultrabook.

Plainly, I(and pbbly many potential customers) would like to know how the evolution from 32nm to 22nm translates into battery duration, lower temperature, thinness and portability while maintaining performance.

The 22nm node shift promised that this time Laptops will finally have a lasting battery, perform and be portable enough to do a whole day of professional work without worries... However last week, it was known we'll have to wait til May, Jun or more till the actual gear get released.
////Hopefully this Mobile CPU line up is compatible wtih todays 988 chipset so those who buy ttoday and 2012 Q1 still get these benefits...
