It is now confirmed that Polaris 10 has 36 Compute Units (2304 Stream Processors), while it's slower brother features 16 CUs (1024 Stream Processors). Smaller Polaris chip is also confirmed to feature 128-bit memory bus.Jun 14, 2016
Polaris 10 features 2304 stream processors across 36 Compute Units (CUs), and supports up to 8GB of GDDR5 memory on a 256-bit memory interface. … It features 1024 stream processors over 16 CUs, coupled with up to 4GB of GDDR5 memory on a 128 bit memory interface.
Polaris is a new graphics architecture incorporating exciting features and improvements for virtually every area of a graphics chip. Look for: increased levels of performance, smooth VR, seamless support for next-gen gaming monitors and CPU-free game streaming or recording.
AMD's Polaris 20 GPU uses the GCN 4.0 architecture and is made using a 14 nm production process at GlobalFoundries. … For GPU compute applications, OpenCL version 2.1 can be used. It features 2304 shading units, 144 texture mapping units and 32 ROPs.
The Radeon RX 470 is a mid-range graphics card by AMD, launched on August 4th, 2016.
AMD's next-gen flagship GPU is said to have made one big step towards launch. … AMD Navi 31 will use the RDNA 3 architecture and should be destined for the Radeon RX 7000-series cards (if the typical naming conventions hold up) that are expected to be released in late 2022.
A CPU consists of four to eight CPU cores, while the GPU consists of hundreds of smaller cores. Together, they operate to crunch through the data in the application. This massively parallel architecture is what gives the GPU its high compute performance.
