More details about the Pascal GPU have been recently shared by NVIDIA in Japan. This next generation of NVidia's graphics cards will offer a whole new speed through the second generation of High Bandwidth Memory (HBM).
Vr-zone reports that with Nvidia's Pascal, the company hopes to build on the fantastic power productivity delivered by Maxwell based cards. The Pascal GPU bears the ability to offer twice the performance per Watt compared to the existing Maxwell architecture, due to its move to new 16nm FinFET process by TSMC.
A 16GB of memory along with four 4GB HBM2 memory chips are projected to be featured in more high-end Pascal based products. NVidia may introduce products with up to 32GB HBM2 memory (enterprise oriented cards only) as well. As for the peak memory bandwidth, it is anticipated to have a 1TB/s on the products that have 16GB HBM2 memory. On the other hand, the internal bandwidth could easily touch 2 TB/s.
Moreover, it is said that two GPUs will be allowed to be interconnected with a bi-directional of up to 80 GB/s via NVIDIA's new interconnect called NVLink. It is considered a substantial upgrade compared to the 16GB/s bandwidth that is being offered by PLX PCIe Gen3 bridge-chip used currently in dual-GPU products.
According to Extreme Tech, Pascal will adopt the next-generation HBM2 memory standard as a replacement of GDDR5, the HBM2 is a 16nm FinFET process at TSMC, and up to 16GB of memory. It is reported that this will be the first product from Nvidia ich which will utilize this technology.
A report from Digital Trends says that the HBM in AMD's Fiji XT-based Fury line of GPUs had an impressive bandwidth. However, it appeared inhibited through the number of gigabytes that could be brought on to the PCB. That issue was reported to be fixed by Pascal since some cards in the new line-up feature as much as 16GB of the high-speed memory.
The upcoming Nvidia's Pascal GPU, the next-generation graphics architecture that will be equipped with HBM2, could be seen during the first half of 2016.
