Quite a few of them
AMD has announced a bunch of fresh DirectX 11 mobile GPUs at CES and the diverse lineup should be enough to meet anyone's needs.
In the high end AMD will offer a choice of three chips, HD 5870, HD
5850 and HD 5830. However, for some reason AMD changed the naming
scheme a bit and the mobile 5800 series seems to be based on the
desktop 5700 series. This will undoubtedly cause a fair amount of
confusion, as most consumers don't really follow the mobile GPU market closely.
Looking at the cheap and cheerful market, AMD will introduce 5600 and
5700 parts targeted at mainstream lappies, as well 5450 and 5470 models
aimed at even cheaper models. The power efficient HD 5430 will replace
the HD 4330 in the ever growing thin'n'light market.
In addition to DirectX 11 parts, the outfit will also launch two
DirectX 10.1 GPUs, which are merely overclocked rebrands of existing
55nm GPUs. Dubbed Radeon HD 5165 and HD 5145, these parts are
apparently based on HD 4600 and HGD 4800 series parts.
