A listing by online retailer Newegg for the unreleased AMD Radeon RX 480 has leaked additional specs ahead of the 29th June release. Newegg realised what they had done and quickly pulled the listing but not before screen grabs had been acquired.
While the listing is a VisionTek Radeon RX 480, the specs are likely to closely match that of the first party editions of the card.
While most of the specs were known, the clock speeds were not. With a core clock speed of 1120MHz boosted to 1266MHz when required. This means the card is capable of pushing around 5 teraflops of info. In comparison the nVidia GTX 1070 has a core clock speed of 1506MHz and boosted to 1683MHz and the GTX 1080 is 1607MHz base clock speed boosted to 1734MHz.
