I previously reported that the new high-end Navi based AMD cards may not arrive until as late as 2020, which is partly due to AMD focussing on custom GPUs for the likes of Sony and Microsoft.
However, there is still some life left in the Polaris architecture, and the mid-range market is arguably bigger and easier to gain some market share from.
So it may come as no surprise that there is growing speculation that AMD is due to release new cards in the form on Radeon RX 670, which may land as soon as this weekend, then the RX 680, which could be in November.
PConline has reported that AMD plans to release a new 12nm graphics card with 2048 stream processors later this month, offering a similar core layout to AMD's RX 570. In this case, AMD's use of 12nm is expected to increase power efficiency and deliver increased performance, making the graphics card more competitive within today's marketplace.
PConline sources “AIB vendors” and lists a release date between October 12-15, also stating that a higher-end graphics card with RX 580-like specifications will release in November.
It is believed the 12nm process will allow AMD to achieve a performance increase of 10-15%, delivering similar gains to what is seen on AMD's Ryzen 2nd Generation processors, which use Globalfoundries 12nm node.
A new Polaris series graphics card will allow AMD to offer higher performance levels at a low price point, creating what is likely to be an excellent mid-range graphics card that could fill in a gap created by the increasing price of Nvidia cards due to the rollout of the RTX technology.
One concern is that if the above is true then AMD is going backwards in terms of the technologies they use, and optimising to use Polaris over Vega means they won't have access to some of the new features introduced in Vega such as Rapid Packed Math and other hardware features like DSBR,
