It seems like more rumors and details of AMD upcoming Radeon RX 590 graphics cards are coming in. This time, Videocardz has confirmed that ASUS is working on a custom variant of AMD's upcoming Polaris Refresh GPU based graphics cards, using their ROG STRIX Gaming design scheme.
ASUS Readies Radeon RX 590 ROG STRIX Gaming Graphics Cards - To Feature Polaris Refresh GPU With 8 Gbps Memory
The rumors of a third Polaris GPU lineup have been floating for a while now. It was rumored that AMD was working on a Polaris Refresh GPU, known as Polaris 30, which would utilize the new 12nm process node to deliver enhanced efficiency and faster clock speeds. It was stated that the graphics cards would arrive sometime in Q4 2018 but we didn't get any more details aside from the fact that it would be aimed at the mainstream gaming market.
Now recently, more details have started to pop up with which have revealed the specifications and some minor details of the graphics card. In a previous leak which showed a 3DMark listing, the AMD Radeon RX 590 graphics card features a clock speed of 1545 MHz, 8 GB GDDR5 VRAM clocked at 2000 MHz or 8 Gbps and a slight performance advantage over the Radeon RX 580 at the same clocks.
Now it's not known whether the chip will feature the same core count as the Polaris 20 based Radeon RX 580 which comes with 2304 stream processors or a different GPU config. We know that the RX 580 and RX 480 have utilized the full Polaris configuration so the refresh should also feature the same core count, with some minor architectural and process improvements that would result in higher performance at a lower power draw.
The latest leak from Videocardz reveals that ASUS is already working on their Radeon RX 590 ROG STRIX Gaming graphics card. The graphics card is labeled as ROG-STRIX-RX590-8G-GAMING and drops the AREZ brand, moving back to ROG STRIX.
ASUS had previously designed the AREZ STRIX lineup exclusively for the Radeon RX 500 series cards after the NVIDIA GPP controversy but looks like they will no longer be using this brand anymore. If the cards are really being prepared right now, we would be looking at more details in the coming weeks for sure.
