Some sites show the 1070 as being faster, others have them as equal, some show the RX 480 edging out the 1070. When factoring in CFX scaling, power/heat/noise, and cost (at least here in the USA), it makes no sense to get two RX 480's at the same tie vs. one GTX 1070. Getting an RX 480 now with the thought of going CFX down the road is still a good option for those who don't care about the noise and heat output and can't afford $440+ today. All of this is especially considering the GTX 1070 can get 15% on air and the RX 480 currently gets about 5% on air.

Ok really, did anyone expect anything different from the second they saw the thread in the index?

Honestly dual 480 isn't the worst idea, but not the best. DX12 will have better support for MGPU soon now that Microsoft is making it easier to include support for multiple GPUs. You save a ton on a quality 1440p Freesync over GSync monitor. Anyone that bought 2x 4GB 480s at launch scored. Harder to sell the 8GB @ $240 each though, $480 vs $400.

So overall slower than Founder's Edition if you include the games that don't scale (many don't). Considering MSI Gaming X (example) is faster than Founder's Edition and can OC past Geforce GTX 1080 FE stock performance, no contest.

Exactly. Like I said, if someone buys an RX 480 today and then 9 months or 1 year later adds another, then good for them it's an easy upgrade path that gives them great performance most of the time. But buying two right now over 1 GTX 1070 is .... not the brightest idea.

One of the biggest reasons I am not a big fan of 250+ watt GPU setups. Anyone that says they don't notice a difference in room temperature (in a normal sized bedroom) after gaming for 1+ hours is full of crap.

They also tested ROTTR in DX12 vs DX11, same with Hitman, and neither have CFX support in DX12 but do in DX11 so scaling should be better overall.

Considering MSI Gaming X (example) is faster than Founder's Edition and can OC past Geforce GTX 1080 FE stock performance, no constest.

So your OP was using a card that is faster than a 1080 and you are comparing it to 480 CFX?

Are you saying that 1080 is a terrible buy then since that 1070 is faster? I mean it is much more expensive than CFX 480s.

MSI Gaming X is a few % faster than Founder's Edition (1070) at stock, for the same price ($449-459 right now):

Geforce GTX 1080 can overclock as well.

The 1080 FE is definitely not a value proposition and is accordingly overpriced. But in our unfortunate reality, it's priced just right because the crowd that wants the best performance possible is buying it as fast as it can be stocked.

Any way you look at it, even when 480 CF beats it in absolute FPS, it's not likely giving a better experience due to double latency and inconsistent frame times, not to mention heat, noise and power.

If you are choosing between the two, a single 1070 is definitely a better choice unless you have some specific need from the 480's you don't get with a GTX 1070.

Basically multi-GPU is still not implemented well enough to be an all-around solution. Nothing has changed. Years ago I would have predicted that the issue would have been solved between the driver and the API without begging game developers to do a bunch of extra work, but that's not happened. The burden of the fix lies on the hardware makers, imo, and they won't expend the resources.

Where are all the power, temp and noise graphs for that card when overclocked? Those always seem to get left out...

Still I'd like to see how a 1080 is a good buy when that card is $200 cheaper and beating it.

They are both using the old driver, 16.6.2 not 16.7.1 which lowered power usage.

The 1070 you are reviewing used a lot more power than stock, and that was before the OCing you are saying it does very well, which will increase power usage a lot.

Extra 25W for higher clocks on average, seems reasonable.



and that was before the OCing you are saying it does very well, which will increase power usage a lot.
By a lot you mean 14-15W, still significantly less than Radeon RX 480 CrossFire in all reviews?



So it would be a >120W gap with OC, thanks for the data.

Also as PCLab and TechPowerUp concluded it doesn't need to be overclocked to beat 2x RX 480 in many 2015/2016 games. Overclocking just puts it ahead in almost all titles, even those that scale well.

Sub 450watts dual GPUs with 8 GB of RAM is scary now? Wth?

Sensationalism at its finest. I'm sure my oc 2500k and oc r9 290 use about 150 watts more than that with just a single card.

Kind of meaningless without perf/watt as it's beating some of those card by more than it uses in power. Also rx480 can be undervolted pretty significantly. Most people can get down to 1070mV from 1150 on the core and the VRAM can do 800mv from 1V. And it's a no brainer because it actually boosts performance by increasing the power headroom.

A single card solution is still better.. but it's not a terrible idea for someone who decides to upgrade their monitor for instance and wants that extra boost down the line. It's an option they aren't going to have with a 1060.

You are right. Zero reason to buy a 1080 when you can buy that card instead.

Marketing thread and posts at its finest. Side note: Would choose the 1070 over xfire 480s.

Yea, to me this is a slam dunk for a single card solution. The only reason I would even consider a multi card solution is if there is no single card that gives enough power.
