Yesterday we had some news about AMD's Steamroller and today some new details have leaked about Haswell, Intel's next "Tock". This 22nm architecture promises Instruction Per Clock (IPC) improvement of about 15 percent and will introduce the new AVX2 instruction set. To be bundled with the Lynx Point chipset as part of the Shark Bay platform, the first desktop versions will be Core i5 and Core i7 dual and quad-core models with GT2 integrated graphics and TDPs ranging from 65W to 95W. At a later date, intel will also introduce the cheaper Core i3 dual-core models with GT1 graphics and 35W TDP. The fastest GT3 integrated graphics solution is reportedly reserved for notebook CPUs.
Haswell's GT2, and GT3 graphics cores will support DirectX 11.1, OpenGL 4.x and OpenCL 1.2 with display output options being VGA, DisplayPort, DVI and HDMI. Apparently, the highest end 'Ultra' Haswells won't support VGA, but this remains to be seen. Performance is rumoured to be around three times that of the current HD 4000, presumably from the GT3 GPU core.
