The Radeon RX 480 is based on the 14 nm "Ellesmere" silicon, fabbed by GlobalFoundries. It's publicly known that GloFlo has a 14 nm fab in Malta (upstate New York), USA. The RX 480 is based on AMD's 4th generation Graphics CoreNext architecture, codenamed "Polaris." It features 2,304 stream processors, spread across 36 compute units (CUs). Its single-precision floating point performance is rated by AMD to be "greater than 5 TFLOP/s." The chip features a 256-bit wide GDDR5 memory interface, with memory clocked at 8 Gbps, yielding memory bandwidth of 256 GB/s. There will be two variants of this card, 4 GB and 8 GB. It's the 4 GB variant that starts at $199, the 8 GB variant could be priced slightly higher. AMD confirmed that the GPU will support DisplayPort 1.4 although it's certified up to DisplayPort 1.3. The typical board power is rated at 150W. The card could be available later this month.
