everyone we're shooting another ask GN episode this one not from the normal studio we are still in California as of this shooting but I don't know if this will go out after we get home probably will so we're in Southern California now today visited MSI cyberpower NZXT will be visiting EVGA and I would power shortly couple companies for visiting cloud imperium games of course but we're not talking about that today today we're doing ask GN so it's always comments in the comment area below you have questions leave your questions down there I'll try and just the next time we tried to shoot this in a nicer area than the corner of the hotel room but the spineless rent-a-cop security guard didn't allow it so we're here first question is from Terrence McCann who says hey Steve when a graphics card is outputting 1600 x 900 signal to a 1920 x 1080 monitor what handles the stretching of the pixels so that it fits the whole scale of the display the monitor is it the monitor of the GPU also what is the process called that is called the scaling as I believe you even said in your you answer your own question and the question so it's called scaling and the process itself there are two components that handle it one is in the monitor ones in the GPU and which one gets used kind of depends on the application or what you've configured in Windows things like that so the the component specifically is called a scalar there are scalars and most monitors not all and there are scalars and GPUs if you have a laptop for example notebooks often don't have a scalar in the display Korean monitors a lot of the Korean 1440p monitors that are cheaper can it be cheaper by eliminating things like the scalar and so in those instances the laptop the Korean monitors that are cheaper when they don't have scalars they will rely on the GPU to handle the scaling of the the resolution so that's what that is and that's how that works on Windows one note here you can actually go through control panel and force it toys use the Jeep you for some reason you preferred that but it's not really not really that important just kind of a side note in case you needed to for some reason but basically the scalar whether there is one or not in a display is just a cost thing and the GPUs will have one if your monitor does not so that's all that's all there is to that answer very easy next question is from reps up who reps up 100 I think he says as a actually kind of big question is it true that GP reviewers use already existing results for newer benchmarks I came across this from another site i was curious to know if there's any truth to it and then goes on to quote whatever the other site is that says i'll be part of this i guess they say what you have to realize is that most big youtube channels keep previous results say the benchmark tarick's for ID and witcher 3 on day one of our x 480 released three months down the line they are testing a gtx 1060 and they get that number and plugins they're already existing results I can't speak for other sites or other channels I can speak for hours only and the way we do it is pretty specific so first of all every article that we published with the reviews which they're often video components for will have a test methodology section that section will define which drivers are used drivers are huge and performance so we take this into account I don't know what sites or channels don't I can't it's honestly not something i've looked into so it's i just i don't know what other people do but the way we do it is if i'm testing say let's take the 10 80s we just did all those liquid-cooled 1080s i knew i was going to be testing at least three 1080s over the span of about a month and i knew that there would be a driver update in that month so the decision we made was let's i don't know the exact driver number off the top my head but it is in the articles one of the seven to two or five seven one of those drivers but the decision we made was basically let's take that newest driver at the time for the first 1080 irie benched the founders edition card so it was retested we weren't taking results from May because that's not a good thing there's a couple factors to it let's go through that first so first of all taking old results often is okay for an old game like metro last light shadow of mordor things like that the reason you see sites like ours and others often using these games that are a few years old in addition to in our case new games like GTA 5 Mirror's Edge and doom is because they provide some level of stability so you can have these older games often don't need to retest them I will retest them at least once for every test pass just to make sure nothing's changed but the two factors that can change our drivers and the game newer games like doom doom is driving me crazy because it pushes a lot of performance changing patches every time one of those comes out we retest all of the cards that are on the bench and that's why every now and then you'll see a purge where we go from maybe 16 cards down to something like four or five I try to do a minimum of five so if you see that that is because there's been a performance change either in the driver and it was a necessary driver or in the game software and we can refuse the patch with games like Assassin's Creed syndicate which I've revived for vram testing the test data for Assassin's Creed syndicate doesn't really change based on the game because even though they haven't updated it recently we're not testing on the newest patch testing on an old one and that's because I'm refusing the patch that we can continue to use old data for cards that we no longer have access to because that's important in that use case so it really depends specifically on what's being tested as for the ten 80s I was talking about so we I knew I was going to be testing 310 80s i retested the founders edition that's for still a lot of work but we did not have to retest a lot of other stuff and basically I picked the newest driver at the time of the start of the first car to reviewing which was the Seahawk and then evj as hybrid came out a new driver was out around the same time we refused that driver because it did not contain major game-changing performance optimizations that we're going to be relevant to our test but I still didn't want to download a new driver because now you're not a hundred percent sure it's in that driver package outside of what they list even though what was listed wasn't relevant to the test so we take the older driver from the seahawk test gigabyte extreme comes along there's a driver update still hanging there from the hybrid but not a new new driver just the one account the hybrid refuse that update we retest the or test for the first time the gigabyte card with the driver that was used for the Seahawk hopefully you're following basically carry the same driver through a series of tests find a stopping point which is the gigabyte extreme car that we just reviewed because i know i'm not looking at 10 ages for a little while and we call it there the next time we look at a 1080 depending on what's going on how the driver landscape has changed if there are specific game optimizing changes at that point we'll decide if we update retest the cards if we still have them or if we just use the existing drivers if nothing really has changed so that's how we do it another factor of this in order to keep some cards like the GTX 1060 in the case of the 1080 review we just did in order to keep some of those cards on the bench but still produce content on a timely manner sometimes we'll use for example in this case the press driver for the 1060 before it was released was used I think for the 1060 cards you find this in the methodology and then the other driver package is used for the 1080s it's all defined in the article the 1060 wasn't the focus and the patch did not contain the driver update to not contain optimizations that were relevant to our testing so we're able to get away with that but all that is very clearly defined and any time we're testing is the important part and it's how we're testing one card specifically against another all the 1080s all the ten 70s although our X 480 is or if we're looking at our x 40 verse 10 60 will download the newest patch drivers whatever for games for the drivers themselves update and then test based on that so I think that kind of explains the way we do it I can't speak for the other sites I can tell you that yes this is something I have taken into account since day one because I know there are big performance changes potentially from drivers and so that's that's all taken into account it is not always possible to use the latest drivers and still see all the cards on the bench in those cases if there are not major critical game optimizing changes then we'll use the older drivers so that's the towel that works next question is from Sergio Eduardo Flores amenah who says wouldn't integrated Ram drastically boost performance on integrated GPS this is in reference to last asked yen where we talked about HP i'm on cpus in the future on coprocessors or on whatever the answer to that is yes because the one of the biggest limiters of I GPS is the system memory speed so that's why you'll see it actually a legitimate performance gain from something like a 2400 or 2133 agar instead of RAM which is maybe 1600 if we're not going to extremely low so the answer that's yes it there's still a HP ms really freakin fast so there's still kind of a cap to where you start running into issues with the limit of C use or whatever depending on what I GPU are using die sizes of limitation certainly so it's there is a limit to basically diminishing returns on something like that theoretically it's not something that exists yet so it's all theory but yeah it would definitely increase performance on IDPs because they're most heavily limited by ram and then after that they're there compute units or equivalent next question Matt McGregor is actually last question for today i'm at mcgregor says love the in-depth QA videos can you question can you damage an aio water cooler 3-pin pump or four pin for that matter running non pwm with voltage control through basically external software speed fan in the cases question and then the next question was if no damage is caused from voltage reduction would it help prolong life of the pump running at slower speeds most of the time by reducing the voltage so i talked some people about this who engineer or at least work at the companies that engineer the pumps to get a clearer answer the answer is for the most part the ideal pump voltage is 12 volts and i guess you could lower it through a hardware or software solution but from what we've been told lowering the voltage to make the pump run at a lower speed won't necessarily prolong the pump life because the pump is spect to outlive basically everything else in the system what will fail first or will cause failure first is permeation of liquid through the tubes and through the system we talked to us before a lot of these coolers are expect to live about five years before they start losing too much liquid to remain at peak efficiency or they start failing the pump has a fluid ceramic bearing in it and that bearing is basically lubricated by the liquid going through the pump so once you start having permeation there's issues there but the pump itself won't fail just from running at 12 volts for its lifespan is the answer to that question I think in the most succinct way possible so that is all for this ask GN for more questions post them in the comments below I'll get to them next week or something hopefully we won't be chased away by a golf cart enthusiast looking out for the business parks interests and its water fountain that we thought looked like a good backdrop as always patiently commercial video how is that directly subscribe for more content I'll see you all next time you
