German tech site 3DCenter claims AMD has changed its Vega launch plans. The new high-end video card from AMD was previously scheduled for a launch in 2017 but if this new rumor pans out the company is doing its best to pull the Vega launch forward to October.
The Polaris series is expected to be launched later this month but these parts will be for the mainstream (Polaris 11) and performance (Polaris 10) markets. Vega 10 is rumored to have 4096 shader processors and a 2048-bit HBM2 memory bus, this card will take on NVIDIA's GeForce GTX 1080 (GP104).
A bit further on AMD's roadmap is the Vega 11, that part is rumored to have around 6000 shader processors and a 4096-bit HBM2 memory bus. This enthusiast-class video card will reportedly compete with NVIDIA's GP102, which allegedly has around 4500 CUDA cores and a 384-bit GDDR5X memory bus. Both Vega 11 and the GP102 are expected in the first half of 2017.
