How hot do high end GPUs get?

[Okjoek]

I've used RX 460 and RX 480 GPU before and some games would make them give off a fair amount of heat and certainly made my room feel a little warmer than other rooms that didn't have a computer.

 

But let's say I were to get something in the weight class of a single Vega 64 which supposedly uses 295 watts. How much heat is that exactly? Like if you were into fairly small houses/apartments would you even need to worry about heating as long as the PC was optimally placed?

 

Probably a really inefficient way of heating a home, but what if you had the system mining something like Etherium or Monero whenever your not using it?

If you're talking about an entire living space, it's not a major concern. In a closed room with minimal circulation, you might encounter shifts in temperature of a couple degrees, but I wouldn't expect anything major. Ultimately the heat coming from a graphics card isn't that much different from, say, a space heater. A 500W space heater doesn't do a whole lot and is best left keeping a desk warm, while a 1500W heater would actually warm a room. A GPU consuming 200-400W is going to do less than a small space heater.

Something on the order of 300 W would definitely heat up a room, most likely by too much to remain comfortable, but it is not likely enough to heat a house, certainly not here at least.  As for efficiency, it's an interesting question.  It's nearly 100% efficient at turning electricity into heat, but so is a room heater, but a room heater doesn't output useful computations as a bonus.  The efficiency of turning whatever your grid uses (coal, solar, etc.) into electricity though is far lower than 100%, and this must be considered when comparing to something like a gas furnace.

depends on how hot the room is to you really... I'd like to have one for warming up my room when it dips below 0C outside tho

Back in the days when people put four high end GPUs in. It can heat up the room fast.

Thing is, if you're not looking at a temporary once-in-a-while heating solution, 100% is pretty bad with modern technology. I've got an air-to-air heat pump at home that gets 200-300% efficiency, depending on outside temp ("efficiency" should probably be in quotes here, but whatever, you get the point. Energy is moved, not created). Ground-to-water heat pumps, while really expensive to install and not doable in apartments, can reach over 600%. It might be fun to look at monero as a possible heating solution, but it is not a good one

Yup also definitely worth some consideration.
