DDR Memory vs GDDR Memory as Fast As Possible 

"and linus has a beard" the most significant thing here

And 9 months after you commented this GDDR6 is the norm and DDR5 is months away

yes linus is very skinny

He does have a beard, he's kinda hot.

This somehow rhymes

That's the basic guide for beginners.

Yeah, as flippant as it sounds, it usually is the case, haha.

i still believe in this theory after watching the video

Somehow, that's true for most technologies, case in point 46 vs. 4G LTE and PCI vs PCI Express

I have ddr4

few months later......GDDR5X

Titan X pascal uses GDRR5X xD

Now 1080ti only gddr5

Oh

ok [APPLAUSE]

really????

I think of Straymav on twitch

So true

Great explanation. That helped alot more than most of what the video explained lol.

Thanks, the thing is about modulation that most people think of modulation of some thing of the past and dial up connections. But looking at USB 3.0, Firewire, HDMI, PCI-E an also in some extent memory busses/ports every single pin have a modulation unit (like a old dial up modem) attached to it. A dial up modem runs at

Probably something to do with the advertisement taking up almost as much time in the video as the explanation.

or the horse joke?

Hell I'd give a thumbs up for that. I love me some shitty jokes.

Advertisements are his way to earn money, without them you would not have this video...

pretty much otherwise its a big slice of your time for nothing. if it was you in his shoes you would do the same. it sucks tho i can buy pc parts from them i live in australia and parts here are way to expensive. but i value the reviews and build guides there verry good and to the point

Well your welcome to pay the channel to make content instead, until then, deal with it :/

lol @ ur profile pic xD

Easy way to get pictures. Go find an image you want. Right click then click save image as. BOOM! You now have the picture to use in your video and you don't pay a single cent for it. Shutterstock is a rip off and a useless service. Why would you need to pay for images when you can take them yourself or download them for free off google.

@@PlatinumEagleStudios pay for it and they will get rid off watermarks for u?

The best answer

In Japan they do!

Graphically it does better. But if one of the games starts taxing the CPU part it will start chugging very quickly.

the ps4 has a apu and so does the xbox one

Malachi Hart Which inside has Cores designated for Serial Computing and Parallel computing. A CPU part and a GPU part. An APU is a hybrid with to processors integrated into one. That still means that when the CPU part is taxed it will be hindered by the GDDR5 Memory.

i know i am, thank you.

It is, in all america

And Europe

NitroHamster I live in Europe and it's not that strange here.

At least in The Netherlands it is, thought it was pretty much the same but guess you are right :)

NitroHamster Dude i live in the netherlands and i can order a ''patatje zuurvlees'' with horse meet in it at any fast food store

thank linus very cool

That is why high frequency DDR ram creates such a drastic difference. This allows the GPU cores to run at a much faster pace, thus buffering through large files easier. High Frequency ram doesn't matter much with CPUs because that deals on a smaller scale there speeding things up may not be an option.

OK... the basic idea is that a CPU can run just by itself in a system, however a GPU can't. it is an add in card that is made specifically to handle graphics. as for clock speeds, most of the time is you turn your clock-speed higher your temperatures will go higher, and also GPU's are for a very particular use and so they would have more power than a CPU ONLY IN THAT PROCESSING CATEGORY. I hope this answered your question, if not I'm sure TQ will see your suggestion.

I guess the focus of his videos are for that kind of people man

well those small difference can be lost and hard to find for PC beginners even when they seems very obvious to the experts.. it's good to have a series where you can get a primitive info..

google the word noob and understand it before telling people that their noobs..

***** GabeN to that! It's amazing how confident the ignorant serfs seem when they boast about their PS4's GDDR5 RAM and how it beats PC's DDR3. Ughhh.

Nikolai Azerbaijan well it can be very beneficial but not in the sense of the hardware. with proper optimization having gddr5 can be a good choice. If game devs tap into huma, objects stored in the shared ram doesn't have to be sent through pcie lanes to the gpu. and there is less memory references to deal with, since the cpu data can be sent into memory can be instantly manipulated by the gpu (normally the data is sent from cpu into the frame buffer then the gpu gets to work on it)

***** He is correct, but to expand on, PC's have separate CPU's and GPU's. (you might not yet understand what the fuck im on about) The PS4 uses both CPU & GPU in one mechanic. its called something like APU. not to sure.

Ah. That explains it. Thank you.

The PS4 architecture is approximately 30% faster than a PC with everything matching. It does not have to copy or move the data around in the memory and both the CPU and GPU can work on it at the same time. It will take 12 months for the big 1st party devs to learn how to use it well though. The PS is a less powerful system than a top end PC but this build is literally the easiest system devs have ever had to work with. Sony is hoping that along with the VR headset the easy access for the devs. to the system will make it a must-have for all gamers.

The PlayStation 4 does use GDDR5, which really the main reason they put this down is because well as a Gamer you have no idea what the difference is... all you see is well GDDR5 has a 5, while DDR3 has a 3... 5 > 3 thus PlayStation Better! Or at least that is what the Marketing Dept. at Sony are hoping you will think. Now this gets a little tricky to explain, but basically the number assigned to them (i.e. DDR2, DDR3, GDDR5, etc...) actually relates to the number of lanes available. Image it like a Motorway (Freeway), with Data being the Cars on it. So obviously it makes sense that more Lanes = More Cars, so there for more Data! \o/ Only the thing is that the Motorway is powering Electric Cars running on it, so the more Lanes you have the Slower the Cars have to Drive because there is only so much Electricity to power them. As such while you might have 3 Lanes of Cars Driving at 100MPH on the DDR3 Motorway, on the GDDR5 one you have 5 Lanes driving at 70MPH. What is even more important here is what happens when these Cars reach their destination.... you can imagine this as a Toll Area at the end of the Motorway before entering the City (Processor) Now natively Processors only support 128-bit (i.e. 1 Lane) Data Bus, but when DDR 2 was introduced; AMD brought in Hyper-Transport, which allowed for 2x 128-bit ... this was later expanded when DDR 3 became available to 3x 128-bit. It actually does work almost exactly like a Toll Area too, handling several data lanes at once... serving each Lane so that they perfectly merge into a single Lane without any slow-down. Still if we were to say use GDDR4 / 5 instead, what we would end up with would be a Traffic Jam because there are too many Lanes of Traffic trying to Merge. GPUs don't have this issue as they natively run at 384 - 512-bit ... so there is no need to even have the Toll Area, especially as you match the GDDR3 - 5 with the native Bit Rate of the GPU. Now what was said in the Video about GDDR and DDR in terms of design, is well semi-true. Remember System Memory is by design more General Purpose, so whoever builds the PC can chose the specifications of your Memory. Low-Latency (measured in CLK Rating) is great for Multi-Task Environments, where-as you can also get High-Bandwidth (measured in CAS Rating) which is far better for Large Data Transfers (e.g. Gaming) With Graphics Memory, as you can no longer swap it out (used to be able to back in the 90s) really they just chose a setup based upon the price-range the card is aimed at. Budget Cards tend to get Latency Focused as they're assumed they'll be used for general Windows / Business / Multi-Media stuff, where-as Gaming / High End Cards tend to get Transfer focused to allow for massive file transfers. It is under the hood actually identical to System Memory, with the one exception it never supports additional features like XMP - which I'm just not going to explain here but it's basically a good way of getting Low-Latency Memory to also support Large Transfers. (extraordinary important for Gaming or Video Encoding) Still you might be wondering... "Alright, I think I understand how Memory works now - but this still doesn't explain why the Xbox One uses DDR3 while the PS4 uses GDDR5" And well, unfortunately I don't know the hardware specifications of the PS4 APU unfortunately - so I can't tell you if it's specially designed with a larger Native Bus than is usually on the A12 "Jaguar" APU to make use of the extra Data Lanes or if (and judging by what Sony have previously done) a simple case of an engineer / executive believing it is better thus it should have it regardless if there is a point or not. I could point to some absolutely puzzling design decisions about the PS3 and PS2 where to this day I still cannot explain to you why they would deliberately include something that could never properly be utilised by the system because of the hardware design. This said given that the PS4 does use the System Memory as a Shared GPU / CPU Memory Space, including where the Frame (Back) Buffer is stored (screen output) then it does make sense to use GDDR5. Microsoft on the other hand opted to include 32MB of eSRAM, which is basically dedicated memory built-in to the GPU component(s) of the APU to handle this then use the cheaper and more reliable DDR3. Which suits their console far more given it does run on Desktop Windows 8, so it realistically needs the Low-Latency a bit more than High Bandwidth. Really at the end of the day were not talking about a major difference right now in terms of performance, but in a couple of years when Developers are trying to really squeeze performance out of these machines the design of the Xbox One lends itself far better to this - while the PS4 has a good chance of being CPU (well APU I guess lol) bound in terms of Performance.

Leyvin360 Wow. Impressive explanation.

Your comment is just as pointless, watch the video and stop letting a comment section upset you.

***** Oh come on, is doesn't get you annoyed when they do that?

wolfstar Lol why do people get annoyed at people who do that?? You wouldn't even see it if you clicked on the video 5 minutes later....

I honestly don't give a fuck. I'm more annoyed that people don't recognise the redundancy in posting a pointless comment about yet another pointless comment.

***** You don't have to be rude jeez.

OS and apps aren't really a benchmark of the underlying system...

SirLugash maybe Not but goes to show that GDDR5 can run better.

Some laptop gpus use ddr3 because its cheaper

actually its ddr3 because gddr3 is just and older version of gddr5

Quiet console peasant, this realm is for master racers.

Why would Microsoft do anything that serves as an improvement in performance when they know how intelligent their customers are?

The Xbox One and PS4 both use the same APU from AMD, but indeed different memory. These APU's are customised by Sony and Microsoft. I think that it depends from the operating system these consoles are running.

I pretty sure, but not 100% sure that the ps4 shares system ram and graphic ram.

***** it does, but PS4 works differently than a PC, even if it uses similar parts

toteu000 No, not really. The PS4 uses an APU, which is a graphics card and CPU in the same thing (It's more complex than that, is basically the idea). Computers have these (A lot of the AMD CPUs are really APUs). And if I shoved 8 GB of GDDR5 into a computer with an APU and no graphics card (The reason people like APUs is that they do graphics better than simply a CPU, so that they don't need a GPU as much), it would basically work the same as a PS4. But that would be dumb.

***** The "but but" was the non so subtle hint at sarcasm but perhaps too much for some...

tmar23 Except it actually DOES bring a pretty big performance improvement. What Linus failed to mention is that memory latency is mostly related to its controller - and every developer that has had something to say about the PS4's performance has only given praise to its memory architecture, so we can cross latency out.

not for people like Linus and entrepreneur company.

It's a service for companies that produce loads of video footage content. Think about all the B-Roll you see on your local news for example (footage not of the person talking), the $250/month is a hell of a lot less than it would cost them to film all of that themselves.

stryk187 sure i know what b-roll is but when I see it on the news it happens to be locally that shutterstock wouldnt have

***** I just meant local news as a general example of what type of company would have need of a service such as that, rather than an example of one that would use shutterstock specifically. Probably not the best example, but you get the point, I hope :)

Yes, and before that, everyone thought RDRAM would make sdram obsolete. DDR is still sdram, so, so much for that idea.

I remember putting the 30 pin SIMMs in my 386, and being psyched about the new 72 pin SIMMs in my parents' new 486. If DDR RAM makes you an old fart, I must be ancient. :)

philipx550 ADHD is great, it is not a disease at all

Not being able to focus on things that one doesn't like is absolutely common. Best would be to exchange with others who are enthusiasts as well?

philipx550 I have the same problem, but when is it ''ADD level''?

philipx550 I also have problems with focusing. When I'm not interested in something I usually go in day dreaming mode in less than a minute. I also get distracted a lot, for example when someone tells me a story but somehow I lose focus and then I have to ask questions like, what did you say, I didn't hear you, again please? Not sure if that's just me or if I have ADD. btw, did you got diagnosed by a doctor?

philipx550 My parents don't really think I have ADD because they don't notice it. I got myself tested at a clinic (there are no results yet) but right then (a couple of months ago) I couldn't really explain what my problems were. (For example. someone would ask me what my problems were and I would only say that I couldn't really focus well (I suck at explaining things). What happens after you get diagnosed with ADD? And do you have any tips and tricks that I could use?
