You're unstable and mad because of a video card release... Gotcha!

So did you go back and see the context of my post? I really want you to get it, but you have to want it as well! You can do it, we all believe in you!

Have it occured to you the 960 is performing like it is because that natural for the arch at that size and segment? And that the same happens for 480? Frontend takes space and power ! And for low cost cards cost is prioritize d.

Yet GM107 was way more efficient than GM206. Weird because that doesn't align with your arguments that that frontend takes space and power.

The 480 flat out spanks the 960 in every dimension and is more like 100% faster in dx12. The 470 will do it no good at 150 usd and my guess is the retail price of 6gb 1060 will be higher than 250 and not faster than 480.

As it should, because as I've already said GTX 960 was the worst Maxwell card and it was made on 28nm. The RX 480 is not competing with the GTX 960. If rumors are correct, in about two weeks it will be competing with the GTX 1060. Even if GTX 1060 loses 20% of GP104's perf/mm2 and perf/w efficiency just like GM206 did vs. GM204, it will still technically crush RX480, being 40-50% more efficient in perf/w and 20% more efficient in perf/mm2. AMD's margins will continue to be squeezed because Nvidia can sell a smaller, less expensive chip for the same or more than AMD.

After reading through more reviews and such, I still think I will be picking up an RX 480, but waiting for an AIB card. It is significantly faster than my old 7950 in many of the games that I play. And power consumption is way less than my 7950, which over clocked is hitting ~275W.

Hopefully will be able to grab a nice Sapphire, or maybe the PowerColor Devil (if priced decently).

The funniest thing is 1070 >> 480 and yet consumes less power, except price it has nothing going for it.
That's a pretty poor argument. The whole purpose of nvidia or amd existing is to make money. One of them is trying to extract at minimum 100% more money for their products. I'm not sure about you but I'm for keeping the extra $250 in my wallet and turning down settings ever so slightly.

I hope this is an early drivers issue : the RX480 is slower than its older brethren.
I am sure it is.

Yeah,from the technical perspective that's a major drawback.
On desktops it can be overlooked by most for the price,both are completely different price and performance segments. But yeah it sure is sad how much it is behind Nvidia in perf/W.

Huh? what you do with your money is only your business but what I said was about architectural efficiency . You can't have a card which is slower still consumes more power, see the problem here? I am not in market for either 1070/80.

I think it's clear what people are saying. A $200-40 card is the best performance per dollar or whatever currency you have. That's it. Done. Finished.

If you're having a hard time understanding that, no one can help you.

Got it. Thanks for clarifying. In the meantime, if someone wants more than decent 1080p performance and/or barely adequate 1440p performance and minimum VR performance, AMD has nothing for them. ALSO, if rumors are true, in about two weeks RX 480 will no longer have a noticeable perf/$ lead, making the 8gb version inferior in just about every metric. Soooo..... I see how it's working out great to AMD's advantage.

This is turning into a pretty poor card TBH, the power consumption is too high and the performance is too low, it's basically a price reduced 970 that seems to do way better in DX12. There so far behind pascal it gives me some pretty serious doubts what kinda chip vega will need to be mm wise to beat the 1080.

Absolutely, it seems Polaris is just catching up/slightly exceeding Maxwell.

You talk as if another competitor has been released. Can you please link me to 1060 card for sale? If so, we can certainly debate these useless measures.

I was dead set on getting one this winter to use as a stop gap for 6-9 months, but that is seriously in doubt now. If GP106 192-bit rumors are true, I think it'll be 10% faster with 6gb vram for $249. Then again, if Nvidia really is supply constrained due to TSMC then it could be $279 and in that case I'd probably just try to get a used GTX 980 for ~$250 that destroy's RX480 oc vs. oc.

You were not seriously going to get one. Cut the crap...

So much hostility.

In AMD's case, I hope they can sell a bunch of these. Reading some other forums, seems public opinion turned on them.

Guess you can't solely rely on "its $240+" anymore. That hype monster sure got the best of everyone. Woof.

Be interesting to see if AIB's can even hit the allegedly clocks or it's going to be ugly.

Quick summary of my learnings that I have posted in the Ethereum thread.

For mining, they are VRAM bandwidth limited. You can drop the GPU to 950mhz @ 900mV and maintain the same speed.

Memory Speed vs MH/s at stock memory voltage and GPU clock
2100MHz - 26.1MH/s
2150MHz - 26.7MH/s
2200MHz - 27.3Mh/s
2250MHz - crash

Power consumption (estimated by GPU temperature, not exact numbers) falls off of a cliff when running at 950mhz/900mV. From throttling (3x in a full size case) to <70* C at full fan speed.

Gm107 is not gm206 arch. Different.
206 is cut down 204.
A 1060 is technically superior and for that the shareholders will profit. The card will have terrible perf value.
Lets wait and have a look at tpu value chart.

I wonder if it is constrained by 32 ROPs vs 64 from the previous generation?

Sure I was. I said so myself several times. Making comparisons to GK104 and Pitcairn when GTX 680 came out, I figured 390x performance was reasonable at 1440p. That would have been a slight regression vs. GP104 when comparing GK104 with Pitcairn.

But nope. We're looking at 390 levels with absolutely no headroom and GTX 1070 power consumption. Like I said, unless Nvidia prices remain elevated or the used market doesn't come down in price, I'll likely get a ~$250 GTX 980. If used 980's are $280+, then I will look into a $199 RX 480.

I think my 7950B is more like 230-250ish watts, I was really hoping this card would be around 390X performance and at 150ish watts, seems to be 15% slower and close to 180W.

price is actually to high for me in Canada anyways seems to be >300 for the 8GB.

It's 100% cheaper than the competitors offering. In my case I bought the $199 4gb which gives similar performance as the 8gb version. So it's $199 vs $430. 116 % price difference

GM107 and GM206 are both Maxwell. 206 had updates over 107, but nothing that should have decimated the perf/w that GM206 scored.

You're right though; lets wait to see if and when GTX 1060 comes out, and where it lands on the value chart.

I perfectly agree vega should have been cancelled and have said so weeks/month ago. You are the first one besides me as i have read have said so.

Looking at the power efficiency of this, and what it'll mean for where they can scale Vega to, you do have to wonder how on earth they're going to get there R&D money back.

Part of the issue here mind, could well be the better binned chips going to the 'core' things like mobile/semi custom things etc.
