AMD "Polaris 30" launches in October - replaces Radeon RX 580 and RX 570

More than two years ago, AMD launched the Polaris graphics architecture, which has recently also become known as the fourth generation Graphics Core Next (GCN). This was launched only for the lower middle class and down, while last year’s Vega with Radeon RX Vega 64 and RX Vega 56 is aimed at enthusiasts.

The first Polaris circuit was named Polaris 10 and was followed the following year by Polaris 20, which according to AMD was based on an “optimized” 14-nanometer technology with higher energy efficiency and increased clock frequencies. Now there is much to suggest that the company is once again giving Polaris new life.

Chinese PC Online writes that they have spoken with several partner manufacturers, who state that AMD will soon launch “Polaris 30” with associated graphics cards. What’s new with the Polaris 30 is not clear, but previous reports have said that AMD is moving production to 12 nanometers from Globalfoundries.

When AMD launched the first generation processors in the Ryzen series, it was on the same manufacturing technology as Polaris. In the spring, Ryzen 2 was released, where the big news was the transition to 12 nanometers, which enabled both higher clock frequencies and improved energy efficiency against Ryzen (1). Specifications such as number of cores and cache memory, however, remained the same.

According to previous information, Polaris 30 should receive a similar treatment and thus not differ in terms of specifications from Polaris 10/20. In other words, it will continue to be 36 computing units with a total of 2,304 stream processors and a 256-bit memory bus.

The first graphics card with Polaris 30 is said to be launched on October 12-15 and will be a variant with 32 computing units or 2,048 stream processors, which is the same number as for Radeon RX 470 and RX 570. This will be followed up later in November by an RX 580 replacement with 2,304 stream processors.
