AMD Radeon RX 550 review: New (entry) card on the block

Not every card is a gamer's card



On you'll find the latest high-end hardware news, but developments in the budget segment are equally interesting. Fresh in from AMD, we'll look at the AMD Radeon RX 550, based on the new Polaris 12 GPU with only 512 stream processors. We’ll see what it’s capable of by looking at the Gigabyte RX 550 Gaming OC.

Looking at the specs, the RX 550 doesn’t really excite; 512 shaders and a clock speed of 1183 MHz with 2GB of GDDR5 memory. At the heart of this card however, we find the newest GPU in AMD’s Polaris series, which means it’s produced on Globalfoundries’ 14nm process. That makes it the first new AMD chip in this segment since the ”Oland” chip from 2013.

Polaris 12 has 2,2 million transistors and, at 101 mm2, has an 18% smaller surface area than the Polaris 11, which is found in the RX 460 and RX 560. You would expect a larger reduction in size seeing as the amount of stream processors has been halved, but two out of ten compute units have been disabled and are still physically present. Beside this, the memory-bus is still 128 bits, using up additional space on the die.

Gigabyte Radeon RX 550 Gaming OC 2GB
For this review, we tested the Gigabyte RX 550 Gaming OC.

 As the RX 550 supports hardware decoding of H.264 and H.265 video in 4K resolution, it is an interesting choice for media centre and HTPCs. Combined with a HDMI 2.0 output, it will have no problem putting this resolution on your screen. With its low TDP of only 50 watts, you will not require a PEG cable to power the card.

Since there is no reference card available for the RX 550, we tested a model from Gigabyte for the reference speeds. On the next page we’ll take a closer look at this card.
