AMD announces Radeon RX 500 series graphics cards based on Polaris architecture

However, AMD contends that the improved 14nm FinFET manufacturing process has allowed it to push clock speeds.

Radeon RX 550: The doorway to PC gaming - Featuring 2GB GDDR5 memory, the RadeonRX 550 delivers up to an average 4X higher performance vs. competing integrated graphics, and up to an average of 1.7X the performance of the RadeonR7 250 at an SEP of US$79.

After about a year of announcing the RX 400 series of budget and mid-range graphics cards, AMD is back with the RX 500 series.

Other than adding support for these new cards, the latest Crimson ReLive 17.4.3 release doesn't seem to offer a whole lot. The RX 580 and 570 should hit stores today, while the 550 will come on the 20th. It is not all that different from the nearly four-year-old R7 250, so it will offer similar sub-par graphics for those who want to test its limits. And with these enhanced Polaris cards, AMD wants to make those stragglers an offer that they can't refuse!

This one is a very modest upgrade. The e-sports oriented RX 560 is also 57 percent faster than the R7 360. It also trades one of the DisplayPort connectors and one of the HDMI ports of the above cards for a second DVI-D port. It will come with Polaris 11. The boost clocks are affected likewise. Again, this card is not particularly meant for some high-end gaming, but it will do the job at medium to low specs. The RX 570 costs $170 for 4GB, with the first cards running between $170 and $200.

The RX 550 has 512 stream processors, 32 texture units, 1183MHz boost clock speed, 128-bit memory bus, 2GB VRAM and 50W TDP. This time around, the jump goes from 1206MHz to 1244MHz. Although not officially listed by AMD, the Radeon RX 580 will also be available with 4GB of GDDR5 memory.

With so many cards falling so close to each other in terms of performance and price, choosing the right card for $200 grows more hard by the day. Having said that, it is now easier to also get the GTX1060 3GB cards for about the same amount, so buyers will have to choose.

While the 500-series is not the most exciting of upgrades, it's good value. The RX 580 runs at 1257 MHz Base and 1340 MHz Boost, while the RX 480 sported 1120 MHz Base and 1266 MHz Boost.

"The Sapphire NITRO+ Radeon RX 580 8GB card itself is 10" long and roughly 5" wide. The only difference between the two cards is the clock speed. The company dropped us a line informing us of its four new graphics cards based on the refreshed Polaris GPUs: ROG Strix versions of the Radeon RX 580 and RX 570, plus a more mainstream "Dual" version of the RX 580. Should buyers be interested in these offerings, though?

Awesome streaming, sharing, and gameplay capture with Radeon ReLive - The Radeon ReLive software suite lets gamers enjoy smooth gaming and recording simultaneously, even on entry-level systems, with support for recording at 4K resolution at 30 and 60 FPS using HEVC and H.264 codecs.
