 Now while you may see something like this on my test bench and assume that this is going to be a video about three-way SLI scaling on the GTX 670, that is not actually the topic of this video. That will be a separate video where I'm going to do GTX 670 three-way versus Radeon HD 6970 three-way because the performance of these cards is pretty close, so I am very interested to see who scales better at a high resolution like 2560x1600. But no, this video is about temperatures, power consumption, and noise. Yes, those three things. The GTX 670 compared to its immediate competition, that is the GTX 680, the 7970, the 7950, the 7870, and the card that it replaces, the GTX 570. So one of the points that I just wanted to make to open this one up, that's why I have three cards on the bench right now, is that even with these three cards, we are drawing less than 100 watts from the wall at idle. This is with an overclocked 4.4 GHz, 3930, 3630K, 3930. Sorry guys, it's like four in the morning and I'm really tired. So it's a 3930K at 4.4 GHz with all the power saving features turned off, 16 gigs of RAM, SSD boot drive, big old XL ATX motherboard, three GTX 670s, and this is running off of a 1250 watt 80 plus cool power supply. So what that means is because this is a 1250 watt power supply, it's extremely inefficient at only 10% load. So in terms of actual power consumption, this system is probably in the neighborhood of about 80 watts at idle, which means these cards are pulling next to nothing at idle. This GTX 670 is very power efficient. I'm going to show you some graphs and charts as well as some audio clips comparing its cooler and its cooling characteristics as well as its power draw to its competition. Now I showed you guys in the introduction that the system is drawing less than 100 watts at the wall. So what that means is that when we have a single card drawing 70 watts from the wall, those two additional cards running in three-way SLI when they're idling are basically almost completely shut down, which is very, very cool. It makes for a much more efficient computing experience because you're not always going to be loading up all three cards with the latest 3D games. Sometimes you have to check your email, and it's great if you're not sucking a ton of power back and paying an immense electricity bill on account of your massive gaming rig. Again, this is totally labeled incorrectly, so I apologize for that. This is power in watts. And then less is better, in case you guys didn't know that. Okay, so what else we got here? So you can see that the GTX 670 is very competitive in terms of its performance per watt because it does outperform the HD 7950, and it performs a little bit less than the 7970, so it falls right into where it's supposed to be. The idle power is very, very, very exciting as well, and you can see it draws just a little bit less power than its older brother, the GTX 680, which stands to reason. When you compare it to the previous generation product, it smokes it not only in terms of performance but also in terms of both gaming load power as well as idle power. So how did I measure gaming load power? Using this guy right here, and then I would stand next to a particular car in Battlefield 3 in the underground parkade where I was getting very consistent power readings from all of the cards that were pretty near the peak that I was seeing during gaming, just glancing at my power meter the whole time. So that's how I'm measuring the maximum power. No, it's not 100% scientific, but it does give you a pretty good idea of what you're going to be able to expect from any of these given cards. And the way I was measuring idle power was just with my spreadsheet here open and nothing else happening. So all of these new fangled cards are so efficient at idle that we only really start to see some separation once they really get loaded up. Now let's talk temperatures. Now these are going to be a little bit tough to compare because the 7950 data especially is not going to be very similar to the other data because this is not using a reference cooler. This is using a Sapphire dual fan cooler that does a, as you can clearly see, significantly better job than the reference cooler that's on the 7970 right there, even accounting for the fact that the 7950 does not run as hot. So bear that in mind, these numbers are not directly comparable between the 670 and the 7950. So the 670 runs pretty much the same temps as its older brother. I measured these using pretty much the same method, so I'm taking the idle temperatures once it's idle at the desktop for, you know, five minutes or whatever and it's pretty much settled into a very flat line and load temps are taken when I'm looking at that same car. So that's after I've been benchmarking for about 15 minutes already with the games beforehand and then I get onto Battlefield 3 and I'm seeing at that point as well a very, very flat line so that's when the temperatures have completely equalized. So this gives you some idea what to expect from a reference card. However, even at launch for GTX 670, there are non-reference cards available already and I'm having trouble finding it right now but I have one lying around here somewhere there you go. Galaxy has a pretty sweet non-reference card at launch that has like a glowing GeForce GTX 670 logo thing going on and dual 92mm cooling fans and it looks just like beastly and everything. So bear that in mind guys, this is just based on reference cards, based on a non-overclocked card and I guess that's pretty much all there is to it. They run about what you would expect compared to similar competition like the HT7970, a little bit cooler at idle, a little bit hotter under load. Now guys you're going to see some clips of just close ups of the video cards like this. These are once again not scientific, these are not meant to evaluate the exact decibel level, noise level of these cards. They are meant to give you an idea of the idle and load signature of the noise so whether it's a low growl or whether it's kind of a high pitched squeal, that is what you guys can evaluate with these clips. It should give you some idea of the loudness of the cards but it's not scientific so just bear that in mind.
