Rumors around Polaris 30
Rumor mills are always churning about Advanced Micro Devices’ (AMD) next GPU (graphics processor units), and this time there are rumors about three GPUs: Polaris, Vega, and Navi. One rumor suggests AMD might launch the third iteration of Polaris under the “Polaris 30” series and the GPU will be built on GlobalFoundries 12-nm (nanometer) node and deliver 15% better performance than its predecessor.
AMD’s 7-nm Vega
At Computex 2018, AMD unveiled its 7-nm Vega GPU targeted at machine learning and AI (artificial intelligence) applications. AMD claims that the 7-nm Vega has twice the density and power efficiency and delivers more than a 30% performance improvement over its 14-nm predecessor.
AMD competes with NVIDIA (NVDA) in the AI space.
- The 7-nm Vega would feature 32-GB (gigabyte) HBM2 (High Bandwidth Memory) similar to NVIDIA’s Tesla V100 datacenter GPU.
- The 7-nm Vega would feature AMD’s Infinity Fabric that interconnects its Vega GPU and server processors in a multi-chip package. It remains to be seen if it can match NVIDIA’s NVLink.
- The 7-nm Vega would also feature deep learning instruction set operations for image, video and speech recognition, and natural language processing.
Videocardz.com stated that the Linux driver, on which AMD engineers work, has been updated with the speed of PCIe 4.0 (Peripheral Component Interconnect Express), which indicates that AMD’s future GPUs like its upcoming 7-nm Vega would have PCIe 4.0 standard that delivers 16GT/s (giga transfers per second) and 16 Gbps (gigabytes per second) of bandwidth, double that of its predecessor.
At the event, AMD stated that a 7-nm gaming GPU is under consideration and might have 16-GB HBM2. Next, we’ll look at AMD’s Navi GPU.
