AMD reportedly prepping RX 680 and RX 670 Polaris graphics cards for immediate release

AMD might be prepping a Polaris refresh for immediate release, with the RX 570 and RX 580 both on the docket for an update. The latest rumours suggests the red team has a refreshed Polaris 30 RX 570 replacement, ostensibly an RX 670, ready to launch by the end of the week. An RX 580 replacement, potentially an RX 680, will follow up shortly after in November. Rumours of a Polaris refresh are nothing new, but they have been few and far between. If AMD has adroitly kept an entire Polaris refresh generation under wraps until the week of launch, it will be nothing short of a miracle in another year of innumerable rumours and leaks. The AMD Navi architecture, on the other hand, has been subject to rumours all year round. The Polaris 30 refresh would likely be produced on the 12nm process node, which has been the basis for second-gen AMD Ryzen CPUs. As James Prior, senior product manager at AMD, told us back at CES regarding the move to 12nm with Ryzen, “it’s not an area statement, it’s a power efficiency statement. The area is not going to change much, but the ability for us to manipulate the frequency voltage curve has improved.”
