Hey glad to see you guys back here on tech of tomorrow I'm Network your host we've got some exciting stuff going on today so what do we got going on today well you guys all know that AMD has finally released their official version of the HD 7990 and that said it was geared to be the fastest card in the world that's what they've been claiming well we're here to set those claims too right and we're going to show you a total bunch of benchmarks and stuff regarding the HD 7990 versus the top-of-the-line card from Nvidia their GTX GeForce 690 now both of these cards feature dual GPU technology on one piece of silicon and they're both considered the top of the line card from both companies so with that said let's jump in let's check out some comparisons and see who at the end of the day who really is the king of the frackin ring so let's start off folks with the GPU code name now the HD 7990 is the Malta it's based on the 20 an ohmmeter process and the GTX 690 is based on the GK 104 also again on the 28 nanometer process now let's talk about core clocks the HD 7990 is a core clock of a thousand megahertz the GTX 690 has a core clock of 950 megahertz but it boost to 1020 megahertz in its boost technology now let's move on to memory clocks the HD 7990 has a 1500 megahertz memory clock the GTX 690 has 1500 and to makers a slight little bump there to megahertz the HD 7990 has 4096 stream processors the GTX 690 has 3,000 72 CUDA cores now a lot of people ask this question over and over and over again I'm going to tell you straight up but I'm not the super most technical genius in the world but I can tell you this CUDA cores and stream processors are essentially the same type of things but basically CUDA cores are geared a lot more to run Adobe type program so if you're running things like Photoshop and stuff like that the CUDA cores are going to work better now anything with OpenCL on the other hand though you're going to get better perform it's off the stream processors so they are essentially the same thing just as some slight differences in the background architecture and how they work now let's talk about the memory interface now you have to remember that these cards are both like having a crossfire card or an SLI card on a single piece of silicon so they're both times two now the HD 7990 it has a 384-bit times two interface and the gtx 690 has a 256 times two memory interface now the HD 7990 it has a memory bandwidth of 288 gigabytes per second times to the gtx 690 of their hand has 192 point 3 gigabytes per second times 2 now I want to just mention something right off the bat a lot of people talk about micro stuttering and all that kind of stuff and you know that if you take you know just 2 2 gigabyte cards and you slept in the system you're not accessing the total 4 gigabytes of available memory but with these 2 cards you get the maximum amount of memory and you get to access at all so the GTX 690 it has 2 gigabytes of gddr5 memory times 2 but you can access all of that at the same time which is one of the more superior things about the designs of both the 7990 and the GTX 690 now the HD 7990 it has 3 gigabytes of gddr5 memory times 2 for a total available memory of 6 gigabytes now let's talk about TDP and the difference between the GTX 690 and the HD 7990 now the HD 7990 it requires 375 watts where the GTX 690 only requires 300 so hats off to the GTX they win this particular category now that we've compared the card spec to spec let's jump in and let's check out the benchmarks and see how the cards do in gaming whoo all right so you guys have seen it we've given you specs head-to-head and now we've given you performance head-to-head now you guys can see that the HD 7990 wins out in almost every test across the board there are a few they're different we'll get to that one thing you want to take note of though anything with OpenCL performance the HD 7990 just totally smokes and kicks ass now there are a few places where the GTX 690 actually wins in the heaven benchmark they win there that's very DirectX 11 heavy also in Batman which is a game geared you know for in video it actually shows better scores and that as well but overall you guys can see that the HD 7990 is actually a faster card and one thing it's kind of noteworthy is that the card actually does run a little bit cooler which is kind of strange you guys saw previously that the TDP value was less on the GTX 690 but in real-world heating we see the GTX 690 is about three degrees hotter than the 7990 running all the same tests in the same type of environment so you guys all know that these cards are both very very frakkin expensive and the differences between the two aren't backed significant yeah of course the HD 7990 ones and a few things and well it really should Nvidia kind of kick back on their laurels and they reached out in two different divisions of technology and kind of kind of just really sat back and wait to see what AMD has done okay AMD has come back to the table now and they have the faster car but the thing is you know as well as I do if you're an Nvidia fan damn do you're going to be going out and buying yourself in HD 7990 you're not going to give a if it has a few screens more for this that's not even going to matter to you but if you're just somebody who doesn't care it all about who makes the card you have no fan attachment whatsoever then you can see the 7990 might be a really good choice for you you just got to really take into consideration how much our advanced physics important to you how much is it because you're not going to get advanced physics using the HD 7990 yes you can install the driver something that gets touchy a lot of people still think that you cannot use physics on an AMD card well that's entirely not true what you do is you just go install the driver off the Nvidia site and you run it off of your CPU not your GPU that's the only real difference so if you're somebody though you think hey advanced physics is my cup of tea then you're really going to want me looking heavier at the GTX 690 now before we wrap this up all the information will be down there below the like button which I know you hit since you're there and we also have something really cool for you guys as well I've got this set of flux in your headphones over here from the people over at SteelSeries and we're going to be giving this away to one lucky person now how do you got to do that well all you got to do is share this video right down there once again buy that like button which I know you're going to be hitting and you'll get a chance to win these headphones and lastly let me just hear your guys opinions if you guys had all the money in the world and it didn't matter which card you guys would prefer to buy and why try to keep it simple and praise guys keep the fan blade comments out of there just leaving a comment that says oh and video wins by default AMD wins by default that's kind of really a quick attitude out take the time to actually think about it if you have the money and you could buy whatever you wanted what would you buy and why I'll pick a random winner out there and kick them down a schwag pack just for being involved with it so I'm Mel Rock this is buddy the dog we're going to head to the park and go to our you know dog thing and I'll see you guys back here on teka tomorrow where if you're not subscribed you're missing out
