AMD has just announced availability of the Radeon RX 480 graphics card. As of right now the card is only available in the larger 8GB variant. The more cost-effective 4GB model at $199 is slated to be released in July. The 8GB variant that launched today will retail for $229. The card is based on the 14nm Polaris 10 silicon and takes advantage of AMD’s 4th generation Graphics CoreNext (GCN) architecture.
The card has 2304 stream processors spread across 36 compute units with 144 TMUs, 32 ROPs, and a 256-bit wide GDDR5 memory interface which holds 8GB. The core clock of the card is set at 1266 MHz, and the memory at 8.0 GHz (effective). At its given clock speeds the card has a memory bandwidth of 256 GB/s, although AMD claims that DCC memory compression technology effectively increases memory bandwidth by 30% in best-case scenarios. Display outputs on the card include three DisplayPort 1.4 and one HDMI 2.0b.
