Old fat spills on all sides. AMD has added two new graphics cards, the Radeon 520 and the Radeon 530. We immediately note that the absence of “RX” in the name is not an error. Both models are desktop and portable products. It is safe to assume that the versions for the former are OEM products.
The Radeon 530 is a 28-nanometer GPU-based third-generation GPU from 2015. This model is available in 320 and 384 stream processors with 5 or 6 computing units. The maximum GPU clock is 1024 MHz, and the computing power is at the top of the 800 GFLOPS. This card can be up to 2 GB of DDR3 or GDDR5 RAM, which GPU combines 64-bit interface with bandwidth up to 48 GB / s.
The second model, the Radeon 520, is a product with an even older GPU, as it is based on the first-generation GCN architecture of 2012. Refreshing the architecture of five years ago is an absolute record on the graphics card market. In the Radeon 520 we have 320 stream processors in five computing units, 20 texture units and 4 ROP units and a maximum clock of 1030 MHz GPU. Peak computing power is 660 GFLOPS. Interestingly, this model does not exist with DDR3 memory chips, only GDDR5. This looks to be a sliced version of the Cape Verde XT processor from early 2012, although we can not be sure. As in the previous case, here also the maximum RAM throughput is 48 Gb / s.
It is worth noting that neither the Radeon 520 nor the 530 supports 4K resolution via HDMI, 4K H264 video encoding and decoding, and HEVC / H265 video encoding and decoding – at any resolution. The 520 also does not support the AMD FRTC (Frame Rate Target Control) technology. By shortening, both “new” Radeons probably just do not support 2017.
