Yesterday Intel announced availability of ultra low power mobile products at Consumer Electronics Show in Las Vegas. Historically, Intel's most power efficient mobile processors had 17 Watt TDP, as compared to 35 Watt or higher for CPUs, used in mainstream laptops. New "Y" series microprocessors have power consumption lowered to 10 Watt - 13 Watt TDP. If necessary, the processors can be configured to use as low as 7 Watt, albeit at a reduced performance level. Two processors, Core i5-3439Y and i7-3689Y, already appeared in the latest Intel's pricelist, priced at $250 and $362. The third model, Core i5-3339Y, is currently listed in Intel's ARK product database as launched.
Three ULV microprocessors are based on "Ivy Bridge" 22nm microarchitecture, and have 2 CPU cores, clocked at 1.5 GHz. The processors support Hyper-Threading, Turbo Boost, and VT-x/VT-d Virtualization technologies. All processors come with HD 4000 graphics, clocked at 350 MHz, which is standard for Intel ULV CPUs. The maximum GPU speed on three released chips is 850 MHz, and their TDP is 13 Watt. Despite of many similarities, there are a few differences between three SKUs. Core i5-3339Y has 3 MB L3 cache, 2 GHz Turbo Boost speed, and it lacks Vpro and Trusted Execution features. Core i5-3439Y adds support for Vpro and Trusted Execution, and increases maximum turbo speed by 300 MHz to 2.3 GHz. Intel i7-3689Y raises Turbo Boost speed to 2.6 GHz, and it has larger 4 MB L3 cache:
|Core i5-3339Y||2||4||1.5 GHz||2 GHz||3 MB||13 Watt||$250|
|Core i5-3439Y||2||4||1.5 GHz||2.3 GHz||3 MB||13 Watt||$250|
|Core i7-3689Y||2||4||1.5 GHz||2.6 GHz||4 MB||13 Watt||$362|
Earlier reports also stated that Intel has one Core i3 and one Pentium "Y" series processors in the works. At this time there is no confirmation whether these CPUs launched or not.
