AMD Polaris and Nvidia Pascal Expected to Launch in June at Computex 2016
The next graphics battle is around the corner as both Nvidia and AMD are set to release their graphics processors with all-new architectures at this year’s Computex event which is being held from 31st May to 4th June in Taipei, Taiwan.
AMD’s fourth generation GCN architecture for new Radeon GPUs is known as Polaris. Built using a 14nm FinFET fabrication process, AMD Polaris brings a new memory controller, new multimedia cores, and a new geometry processor. With all these exciting features on board, the upcoming Radeons are expected to deliver huge power efficiencies, improved speeds, as well as better leakage characteristics.
As of now, it’s not clear whether Globalfoundries or Samsung is working to develop AMD’s new 14nm FinFET GPUs. What we are sure about is that Polaris chips will support both HDMI 2.0a and DisplayPort 1.3, and are equally capable of encoding and decoding H.265 video up to 4K resolution.
AMD has already announced at its Sonoma event that it won’t leverage its involvement with High Bandwidth Memory, at for some models. Instead of jumping for HBM across the entire desktop and mobile product line, the chipmaker said it will continue relying on GDDR5, or a variant of it called GDDR5+.
For Nvidia, the stakes are much higher for its upcoming Pascal GPU architecture, which is built on TSMC’s 16nm FinFET manufacturing process. Talking of the flagship GP100, aka Big Pascal, the GPU will feature four 4-Hi HBM2 stacks to achieve 16 GB of VRAM in total, and 8-Hi stacks to reach up to 32 GB for the professional compute SKUs.
If a previous report is to be believed, GP100 GPU will have at least 12 TFLOPS single precision and 4 TFLOPS double precision performance at memory bandwidth of 1024 GB / sec. It includes nearly 17 billion transistors in a relatively smaller packing, offering up to twice the performance per watt improvement over the predessor Maxwell.
Nvidia is expected to unveil the new architecture at the GPU Technology Conference (GTC) 2016 in April, with the announcement of the new GTX 1080/1070 GPUs expected in June. As for the availability, the high-end parts should hit the market during Q3, while the mainstream Pascal-based graphics cards are rumored to launch sometime in the fourth quarter.
