CPU World reveals the package configurations of Intel's Haswell processors.
For desktop processors there will be two versions; a quad-core and a dual-core version, both with GT2 graphics and a dual-channel memory controller that supports up to 32GB. Performance laptops will get quad-core chips with dual-channel memory controller and the faster GT3 integrated graphics, while the quad-core mainstream laptops will stick to GT2 integrated graphics. Additionally, Intel also has a dual-core mainstream laptop variant with GT2 graphics and dual-channel memory controller, but support for only 16GB RAM.
Then there are also the Ultra Light and Thin (ULT) processors that integrate the Lynx Point chipset on the package, they will ship in a dual-core variant with GT3 graphics and a dual-channel memory controller that supports up to 16GB, and a dual-core model with GT2 graphics, single-channel memory controller, and 8GB RAM support.
The site hasn't heard anything about package options with GT1 graphics, but suspects these chips will essentially be GT2 parts with a number of execution units disabled.
