Samsung Start Production of HBM2 Next Year

Samsung announcing at IDF 2015 that it will begin mass production of HBM2 early next year.

As off now HBM1 is limited to just 4GB and 512GB/sec, but HBM2 will be capable of driving far past 8GB and around 1TB/sec memory bandwidth. Professional cards are expect to have up to 48GB of HBM2, with consumer cards most likely to have around 8-12GB of HBM2.

HBM2 is going to change the GPU market, especially when we begin seeing professional video cards with 48GB of HBM2 with up to 1.5TB/sec of memory bandwidth. Today’s fastest GeForce cards feature only 334GB/sec of memory bandwidth, while the HBM1-powered Fury X from AMD packing 512GB/sec bandwidth. It will be interesting to what NVIDIA come up with next year.
