Haswell does come with decent integrated graphics, but most gamers will still want discrete graphics cards and our sources claim that as much as 90 percent of Haswell discrete graphics card design wins went to Nvidia.
This would mean massive loss of market share for AMD in mobile GPUs, but the same sources do indicate that AMD has more than 90 percent of notebooks based on AMD Trinity or Richland chips. Some vendors will offer AMD graphics cards together with Haswell CPUs, but we hear that the number is much smaller than with the last generation.
Haswell notebooks are expected as of June, especially the high-end gaming machines with quad-core processors and most of them will be announced in early June. The fastest of all Nvidia chips should be the Geforce GTX 780M mobile edition and we heard that it should come at about the same time as Haswell, roughly over the next two weeks.
