AMD lancerer Radeon RX 500 serien
AMD har tunet lidt på deres Polaris chips, og lancerer nu RX 500 serien. RX 580 og RX 570 er identiske med RX 480 og RX 470 med hævede clock frekvenser, mens RX 560 bliver en fuldt oplåst udgave af RX 460. Samtidig lanceres en ny RX 550 til at tage sig af det helt lave segment. Med HDMI 2.0b og HEVC H.265 4K dekodning vil dette også være ideelt i et mediecenter.
For ejere af RX 400 serien er der ikke tale om den store forskel. De fleste tests viser 5-10% bedre ydelse fra RX 480 til RX 580. Dette er AMD godt klar over, og deres marketing handler heller ikke om at overtale RX 400 ejere til at skifte grafikkort, men er derimod rettet mod ejere af tidligere generationer som R9 380X og GTX 970.
Der er heller ikke tale om AMD's kommende Vega chip, så dem der sidder med R9 290(X)/390(X) eller Fury må væbne sig med lidt mere tålmodighed. RX Vega skulle dog blive lanceret senere i Q2, og rygterne lyder på maj inden Computex.
Et overblik over RX 500 serien og sammenligning med RX 400 kan ses i tabellen herunder. Bemærk dog at der er tale om reference clocks, og grafikkort producenterne vil have deres egne udgaver, så hold godt øje med clock hastighederne.

NEWS RELEASE
Radeon™ RX 500 Series: The Most Compelling Graphics Card Upgrade Yet. Designed with the perfect balance of performance and features for the 9 out of 10 gamers that play on outdated graphics cards.
SUNNYVALE, Calif. — April 18, 2017 — Today AMD(NASDAQ: AMD) introduced the Radeon™ RX 500 series, a new line of graphics cards featuring a powerful combination of improved game performance, higher clock speeds1, and a refined 2nd generation Polaris architecture, giving PC gamers the best reasons yet to upgrade their graphics. The Radeon RX 500 series was designed specifically for system upgrades, catering to the 9 out of 10 PC gamers today who are hindered by outdated technology and aren’t able to enjoy optimal experiences in modern games, smooth VR experiences, or the latest display technologies.2,3 Radeon™ RX 500 series graphics cards feature a variety of the most compelling new technologies and features including:
- Optimized DirectX® 12 and Vulkan® gaming – The Radeon™ RX 500 series was engineered using the 2nd generation Polaris architecture. It was specifically designed to perform exceptionally well with low-level, next-generation APIs like DirectX 12 and Vulkan and it supports asynchronous compute for outstanding game and VR experiences.3 Radeon RX 500 series GPUs have been further refined with higher clock speeds, improved idle and multi-monitor efficiency, and the fine-grained controls gamers need to fine-tune their hardware
- Improved response times, more efficiency, and cooler operation with Radeon™ Chill – Radeon Chill is an advanced framerate controller for the Radeon™ RX 500 series that works automatically in the background (when enabled) to dynamically regulate framerates in today’s most popular games based on the speed of mouse movements and the gamer’s activity in a scene
- Smooth, stutter-free gaming with Radeon™ FreeSync – Gamers can enjoy smooth framerates in virtually every game released, without the frustration of screen tearing and input lag using Radeon FreeSync, available on a wide range of affordable displays.5 For those that want to get even closer to pixel-perfect gaming, Radeon™ FreeSync 2 monitors harness low-latency, high-brightness pixels, excellent black levels and a wide color gamut to display high dynamic range (HDR) content, and feature Low Framerate Compensation (LFC) enabling stutter-free gaming when framerates dip below a monitor’s refresh rate, all in a completely plug-and-play experience that eliminates the need to tweak settings in software or on the monitor.
- Awesome streaming, sharing, and gameplay capture with Radeon ReLive – The Radeon™ RX 500 series supports the industry’s most revolutionary solution for capturing, customizing, and sharing gameplay. 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.7 Radeon ReLive also integrates with the most popular game streaming platforms around the world
“Radeon was built on the promise that all gamers can enjoy the most advanced graphics technologies in their favorite games. Our launch today of the Radeon RX 500 series doubles down on that effort. With higher performance, revolutionary gameplay capture software, latency-reduction technology, Day 0 driver support for game launches, open and affordable standards like Radeon FreeSync, and innovative features like Radeon Chill, we know gamers who have been patiently waiting to upgrade will have more than enough reasons to now,” said Scott Herkelman, corporate vice president and general manager, Radeon Technologies Group.
A wide range of Radeon™ RX 500 Series cards will be available to meet the needs of the overwhelming majority of gamers:
Radeon™ RX 580: For smooth 1440p gaming – The Radeon RX 580 delivers up to an average of 57% better performance compared to the Radeon™ R9 380X in testing8, delivering smooth gaming in leading AAA games and VR experiences for an SEP of US$229 for the Radeon™ RX 580 8GB GDDR 5 graphics card, and an SEP of US$199 for the Radeon™ RX 580 4GB GDDR5 graphics card
Radeon™ RX 570: For maximum 1080p gaming – With 4GB of GDDR5 memory, the Radeon™ RX 570 boasts up to an average of 2.3X better performance compared to the Radeon™ R7 3709 for an SEP of US$169
Radeon™ RX 560: For efficient 1080p gaming – With 2GB of GDDR5 memory, the Radeon™ RX 560 delivers up to an average 57% higher performance of the Radeon™ R7 36010 for a fluid and smooth gaming experience in the world’s most popular games at an SEP of US$99
Radeon™ RX 550: The doorway to PC gaming – Featuring 2GB GDDR5 memory, the Radeon™ RX 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 Radeon™ R7 250 at an SEP of US$79.11 The Radeon™ RX 550 is also ideal for home theater PCs with support for HDMI™ 4K60, 4K playback and HEVC content.5 It’s also HDR ready, supports Radeon FreeSync 2 technology for smooth, tear-free gaming, and ships in many low-profile designs ideal for small form factor cases
Radeon RX 580 and 570 graphics cards from major AIB partners are available from retailers and etailers around the world starting today*, and the Radeon RX 550 graphics card is expected to be available April 20th.
