Radeon RX 480 "Polaris" Launched at $199

New statement on power issues

We promised an update today (July 5, 2016) following concerns around the Radeon RX 480 drawing excess current from the PCIe bus. Although we are confident that the levels of reported power draws by the Radeon RX 480 do not pose a risk of damage to motherboards or other PC components based on expected usage, we are serious about addressing this topic and allaying outstanding concerns. Towards that end, we assembled a worldwide team this past weekend to investigate and develop a driver update to improve the power draw. We're pleased to report that this driver-Radeon Software 16.7.1-is now undergoing final testing and will be released to the public in the next 48 hours.

In this driver we've implemented a change to address power distribution on the Radeon RX 480 - this change will lower current drawn from the PCIe bus.

Separately, we've also included an option to reduce total power with minimal performance impact. Users will find this as the "compatibility" UI toggle in the Global Settings menu of Radeon Settings. This toggle is "off" by default.

Finally, we've implemented a collection of performance improvements for the Polaris architecture that yield performance uplifts in popular game titles of up to 3%. These optimizations are designed to improve the performance of the Radeon RX 480, and should substantially offset the performance impact for users who choose to activate the "compatibility" toggle.

AMD is committed to delivering high quality and high performance products, and we'll continue to provide users with more control over their product's performance and efficiency. We appreciate all the feedback so far, and we'll continue to bring further performance and performance/W optimizations to the Radeon RX 480.

490 will be a dual Polaris chip surely?

i do not see that happening, unless AMD come up with some miracle solution for it to perform as 1 GPU.

Doubt it, the dual card just came out I don't see another for at least 1 year. Also needs too be room for Vega too slot in later this year/start off next year.

well AMD announced 2 architecture for their single line up, so how different polaris would be from Vega ? not much if you ask me, so it's probably just die size with some minimal changes, the release date of vega was probably set according to HBM availability, and probably yield efficiency at some degree.

Full Vega is meant to be HBM, small Vega... could be GDDR5...

Strategically this would make sense if they decided early last year to play it safe (sensibly imo). They would want a reliably higher volume consumer part through 2017 and a rev2 Polaris won't cut it for the consumer market once Vega and GP102 are out. No reason to have both Vega chips supply potentially constricted by a more complex and likely lower volume production process, and they don't necessarily need 4 GPU's (assuming 2 per Vega die - full chip and 1 cut down chip) with HBM from a performance/power perspective unless both Vega chips are actually quite large. Big Vega would stand to receive the most benefit as it will be pushing closer to power budget limits and also make useful use of the bandwidth, whereas small Vega could very well make do with 256bit gddr5x. Time will tell but seems probable, and really depends on how well they foresaw the market and forecasted the state of the supply chain (GF process, interposer assembly and HBM availability) about a year+ ago.
