It is still called GPU, as it is a graphics processing unit. Just that it's not a graphics card, but a graphics chip.

Haswell, the IVB successor will get a much more powerful - i expect about twice the speed on certain benchmarks, maybe not all. Of course intel could optimize the drivers for a certain workload (like the source 2 engine) but most likely amd will be still faster - only compared the combined cpu+gpu solutions. As always the number of possible sales will impact drivers. It's all about making money.
