Vega 56 Electricity Cost of Ownership vs. GTX 1070

Nice, so unless you run the card at OC with full load for 8760 hours straight (24/7) , the difference is negligible, seeing as most users run for about 4 hours per day.

Would have been nice if they ran in balanced and power saver as I have a feeling it would be a wash, guesstimating would be about $16 more over a 1 year period. The RX draw more power via the 8pin connectors however draw significantly less through the PCIe slot.
 
they need to double it if you live anywhere you need air conditioning

300 watts of heat takes 300 watts of air conditioning to remove
 
Yeh it's not just about the power consumed and psu required, it's also about the heat dumped into your room.

No matter which way you slice it, vegas inefficiency is a pretty big negative.
 
PC has been proven just as efficient as space heater in generating heat from watts. In a few months you will be able to run the vega on watts you would otherwise be sending to your heater.

However, if your house is freezing and you already have a high performance gaming computer -or you simply want to know that your gaming addiction isn't actually increasing your power bill in the winter- our testing shows that a PC is just as efficient at creating heat as a space heater. In fact, you could even set the computer to mine bitcoins to make a heat generator that helps pay for itself! So when you wake up or get home to a freezing cold room, start up those games, folding@home programs, or benchmarks to get your room nice and warm. Its just as efficient as using a space heater, and much more entertaining.

Meh the whole power draw thing is such BS. People are massively over blowing this crap. Especially as multi-GPU becomes less of a thing.

Price/Performance ratios, Frame rates, Features and how loud the cooler is are all way more important.
 
Yeh heat and psu required are my main concerns, but even power consumption per year should be added to price.

I could just imagine Vega CFX in my summers.. LoL

I highly doubt most people even run for four hours a day, unless they're kids. Even if you play online games, you'd have to play four hours each and every day. Some people? Sure. Most people? No way.

I'd have to say over the course of a year I doubt I even average half an hour per day under full graphics load. When I play, I play longer than that, of course, but in reality I only play beat about one game per month. So, most of the time I'm idle at the desktop either doing productivity stuff, browsing the internet or watching a movie.

With that being said, the heat generated is no joke. At least 6/12 months of the year it's pretty hot where I live, and we rarely ever run the AC (it's not that hot and cools off at night). So, having a card pumping out a ton of heat is a definite minus.

i went from 7950 to 390X then to Fury Pro. My electric bill isn't affected much at all. Very very small difference. It's not really concerned for me. lol...but everything else is more hog since like AC central, dryer, etc by how much do you use them.

Well power is proportional to heat, so that is more heat that has to be dissipated meaning more noise. So yeah in one sense I agree that most people aren't going to notice the increase in their power bill, and therefore are overblowing the power consumption thing. On the other hand they are going to notice the extra heat and noise due to that power consumption, so yeah it isn't overblown. Oh and more heat = less time at max clocks which means less frame rates as well, so yeah i hear people care about that too.

Bill,

1w of power to a typical A/C can cool about 3.5w of heat. It is not a 1:1 ratio.

https://en.wikipedia.org/wiki/Coefficient_of_performance

In the winter you would not have to pay as much for heating so the difference would be solely the difference between the two cards. So depending where you live ~33% of the time you would have to cool the extra heat at 1/3.5 rate per watt increase used on Vega.

So for 100w, cooling would be around 30w additional to be added on top of the two card difference for 1/3 of the year. Basically add 10w over the difference.

Honestly, at the rate some upgrade their hardware for the next shiny thing that has maybe 10% improvement, be it a motherboard upgrade and CPU generation for socket 1151 ( Looking at you Demo but others as well...:p ;) ) , where even if they sell their "old" gear, they're still out of pocket by quite a bit, making a big deal of Vega's extra power consumption from a financial burden perspective is both strange and funny at the same time...:lol:
 
It's less the power, and more the heat output for the desired performance for me; living in a warm climate, in summer this thing will be a space heater that I do not want or need.

I will do 1080TI for now, and then see what Navi brings to the table.

Dear Navi,

Please bring steak. Big, thick, juicy steak. If you bring another cucumber salad, I'm not inviting you back.

Sincerely,

Motherboard.

it was ballpark :hmm:

I've only worked in HVAC since 1978
a typical 3.5 ton A/C draws 21 amps at 240 volts here on a 110f day or 5040 watts the more load from your computer you put on it the longer it runs in a cycle


and I live in Phoenix I have had to run my cooler on Christmas day :lol:

........

as for Vega
two fury x's warms my office so it is the hottest room in the house I sure don't want two hotter Vega's

Under those conditions, any high end card will output a lot of heat.....Even a GTX1080TI is a card rated at 250 watts TDP if it isn't overclocked, the vast majority of the power being fed into the card's GPU and ram switching their transistors on and off only comes out one way.......Yup, Heat.


I'd look at a GTX 1070 ( 145 watts TDP ) or at most a GTX1080 (180 watts TDP ), as the limit under a hot climate while still resorting to standard air cooling, and hoping to keep the system quiet even in those hot days.

:hmm: no one runs their card in fashion that it can't hit it's max stable stock clock 100% of the time do they? If you couldn't, you have a cooling problem you need to resolve asap.

It's an interesting thought though. Whats the exhaust temp coming out of these cards? And is really going to be a noticeable difference from it's competitors?
