AMD Readies Radeon RX 490 for December?
A spectacular rumor doing rounds has AMD sign 2016 off with a new high-end graphics card launch. The company could launch the Radeon RX 490 by the end of the year, according to an Guru3D report. This SKU could either be based on the larger Vega 10 silicon, or be a dual-GPU on a stick graphics card based on a pair of Polaris 10 "Ellesmere" chips. The former seems more likely as multi-GPU support among recent AAA game launches is dwindling. Earlier this year, AMD inadvertently leaked the SKU name Radeon RX 490 on its website.
If the Radeon RX 490 is based on the Vega 10, then it could feature 4,096 stream processors based on the "Vega" architecture, 256 TMUs, 64 ROPs, and a 4096-bit HBM2 memory interface, holding 8 GB or 16 GB of memory, with a memory bandwidth of 512 GB/s. If instead it is a dual-GPU card based on Polaris 10, then you could be looking at 2x 2,304 stream processors, and 16 GB of GDDR5 memory across two 256-bit wide memory interfaces.

They need >50% to compete with GTX 1070.
That being said, I'm firmly of the opinion that even the 480 was stretching the performance\efficiency of Polaris, and that the next AMD cards will be a 490, almost certainly being Vega 11, and a Fury card for Vega 10.
- GameStream > 60 fps, low latency gaming while my PC is running upstairs. It works very, very well. Yes, Steam can do it too... on a separate PC. The SHIELD is that stand-in HTPC.
- Media server > granted, consoles do it too. But I'd much rather be on the Android TV platform than on a semi-closed console ecosystem where support relies entirely on one company, and their policy does tend to change. I haven't forgotten the PS3 media server woes either... none of those with SHIELD. Not to mention the power consumption difference - it is significant comparing SHIELD to console - five to eight times less power.
- Responsiveness > SHIELD is easily the most responsive Chromecast you can get. The machine boots up in 10 seconds, usually it's on before my TV is starting to give me an image.
- Voice search > with the Shield remote (I got one free with my shield, standalone its way overpriced I agree) you've got voice search at the touch of a button alongside 4-way navigation. The voice works, and it works flawlessly.
- Size > it's compact and very flat, fits almost anywhere, while the consoles are pretty bulky in comparison.
Is it too expensive for what it does? Purely on the hardware, yes it is. But it does offer some functionality and ease of use that is pretty unique.
BTW it's not more expensive than a console but cheaper than a console, and consoles only play console games, not PC streams.
None of those are essentials (or even that useful) features by a long shot.
Its great it suits your needs in a highly specified niche, but all in all, PS4's & XB1's do what your asking much better at a same or cheaper price.
The only nVidia apu worth mentioning is the "rumored" one in Nintendo Switch. And that one isn't that great either.
- At stock RX 480 performs lower than GTX 1060 while being much less energy efficient, this problem will grow exponentially when overclocked another >50%, even with cherry-picked chips.
- The clock speeds would have to be at least ~1800 MHz stock, ~2000 MHz average boost and probably ~2400 MHz max boost. And even then the throttling will make it worse than GTX 1070 in many games.
- This chip would consume ~230 W on a die size of 232 mm², this would require a very good cooler.
- Anything pushed this far would never be reliable over time.
- Polaris 10 doesn't and can't support HBM. A switch to HBM wouldn't help anything either, GDDR5(X) is more than enough.
Meanwhile in the real world…
A 1060 for example is demonstrably slower than a 480 in most AAA titles this year, and on occasion, rather significantly. The power consumption argument is a bit shit - whilst we know that Polaris can be rather energy efficient, AMD has been bottom binning all of its desktop GPU dies (with embedded and other markets getting better bins). So whilst one can't make sweeping statements that Polaris isn't as energy efficient as Pascal (as its an architectural comparison), in the consumer market, Pascal certainly is.
That being said, Pascal for oath should be more energy efficient, considering a good chunk of functionality is missing off the die, which has been the case going all the way back to Kepler.
Market share shifts. The market shares for the desktop discrete GPU suppliers shifted in the quarter too.

I think Vega will need to compete with Pascal and when Volta drops next year I expect AMD discrete GPUs to take a hit since they plan Navi for 2018 which is a long time for Volta to sit unopposed in the market.
Off Topic: PC Gaming very healthy even though PC sales continue to decline
From the article: "If anyone doubted that the PC was the platform of choice for gaming, this quarter’s results will correct that misconception. The gaming market is lifting the entire PC market and has overwhelmed the console market."

Another example of AMD's preferential binning. The macbook pro can get a full fledged RX460 that is sitting at a 30w TDP.
Hell my cards with a massive overclock are still only hitting the 150-200w range with a voltage bump and air cooling.
