Runner up is Baseline
In the universe where Haswell comes as two-chip platform, formally referred to as Shark Bay 2-chip platform by Intel, there will be three mobile chipsets. The HM86 is targeting at mainstream consumers, HM87 targets Premium consumers and SMBs, while the top one QM87 targets the hard working corporate market.
Things get a bit simpler with the Shark Bay 1-chip platform. The value consumer chipset is simply called Baseline, while the next one is simply called Premium. It can’t get any simpler than that. The Shark Bay 1-chip Platform has same I/O, or what we call a chipset, integrated on either Haswell U or Haswell Y processors line.
The Premium chipset supports Windows 8 connected stand by, Intel Active Management Technology 9.0, Intel Small Business Advantage, ACHI and Raid Rapid storage technology, Intel Insider, Intel Anti-Theft Technology, wireless display and three independent displays.
The list goes on with 8 USB ports where two to four can be USB 3.0 ports, up to 6 devices with PCI express 2.0 5GT/s, four SATA ports capable of 6Gbps. The chipset doesn’t have VGA or LVDS as the CPU has the graphics on it, but the Premium chipset has two sensors interface with I2C and UART, 1.5 to 5MB firmware support, Anchor Cover, Platform trust technology and Platform Flash Armoring technology.
Getting away from numbers and naming the chipset simply Premium means that U and Y line of CPUs are meant for tablet and Ultrabook markets, where manufacturers want you to love the product as a whole, not specifics. Premium and Baseline chpisets for Y and U line Haswell processors capable of TDPs as low as 13W are coming in Q3 2013.
