Looking at the power requirements of the three last generations of Intel desktop microprocessors, it's easy to notice that their dissipated power steadily goes down with each new microarchitecture. While dual- and quad-core Nehalem CPUs had 73W and 95W/130W TDP, Sandy Bridge architecture had it lowered to 65W and 95W, which was again reduced to 55W and 77W for Ivy Bridge. This trend was less noticeable in mobile microprocessors, where TDP stayed at the same 45 Watt or higher for quad-cores, 35 Watt for mainstream dual-core processors, and 17 Watt for ultra-low voltage processors. This will change next year, when Intel's Haswell microarchitecture introduces 10 Watt category for mobile CPUs. Even before that Intel will release 5 Ivy Bridge SKUs with 13 Watt or lower Thermal Design Power. Specifications of these microprocessors were revealed yesterday by VR-Zone.
Pentium 2129Y is the only upcoming part with stock 10 Watt TDP. This dual-core CPU comes with 1.1 GHz operating frequency, 2 MB L3 cache, and HD graphics. The 2129Y does not support any advanced features, like Hyper-Threading, Turbo Boost and Vpro.
Core i3-3229Y boasts better CPU performance than Pentium 2129Y, but at the expense of higher 13 Watt TDP. The processor is clocked at 1.4 GHz, packs larger 3 MB L3 cache, and adds support for Hyper-Threading technology. On-chip graphics on the i3-3229Y was upgraded to HD 4000.
Core i5-3339Y, i5-3439Y and i7-3689Y have 100 MHz higher clock speed than the i3-3229Y. New feature on these models is Turbo Boost technology, that may "overclock" processor by 500 MHz, 800 MHz or 1100 MHz, depending on SKU. Core i7 chip has 4 MB L3 cache, and both Core i5-3439Y and i7-3689Y received Vpro support.
Although Core i3, i5 and i7 microprocessors are rated at 13 Watt TDP, they also support cTDP Down mode, that allows OEM manufacturers to limit TDP to 10 Watt. If necessary, all "Y" processors may fit into even lower 7 Watt thermal envelope, which very likely will result in significantly reduced performance.
All future ULV microprocessors have integrated graphics operating as high as 850 MHz, and they support DDR3, DDR3L and DDR3L-RS memory with data rate 1600 MHz. The processors will be produced in a BGA package. The CPUs are expected to launch in the first quarter 2013.
