WEBVTT 00:00:00.080 --> 00:00:07.919 When NVIDIA announced that its new Pascal consumer GPUs wouldn't be using 00:00:04.640 --> 00:00:10.480 HBM2 video memory, some folks were left 00:00:07.919 --> 00:00:15.120 feeling a little confused. However, that isn't to say that they didn't change 00:00:12.160 --> 00:00:22.080 anything about their VRAM, as these cards are using the also newly released 00:00:19.560 --> 00:00:26.720 GDDR5X. So, what's special about it other than the fact that it has an X in 00:00:24.400 --> 00:00:32.680 its name, which might be trying to remind people of words like exciting, 00:00:30.279 --> 00:00:37.520 extreme, or expensive? Well, that might depend on 00:00:34.960 --> 00:00:43.680 who you buy your components from. So, instead, let's talk about what GDDR5X 00:00:40.640 --> 00:00:45.840 actually is. It's a type of video RAM 00:00:43.680 --> 00:00:51.200 which does things like hold textures, store images in frame buffers, provide 00:00:48.320 --> 00:00:55.440 the GPU with lighting information. In short, it holds the data that your GPU 00:00:53.120 --> 00:00:59.920 actually has to process so that your computer will display your game 00:00:57.440 --> 00:01:04.080 properly. But the arisen question is what's special about GDR5X in 00:01:02.160 --> 00:01:08.640 particular, and is it going to make your games look any better or run faster? 00:01:06.240 --> 00:01:12.240 Well, usually VRAM tends to matter more the higher the resolution your games are 00:01:10.560 --> 00:01:16.799 running at, making it especially important for multimonitor setups or if 00:01:15.040 --> 00:01:22.000 you're trying to run things with aggressive anti-aliasing or high-res 00:01:19.840 --> 00:01:26.560 texture settings. As these things require more stuff to be held in memory. 00:01:24.799 --> 00:01:31.040 And with games becoming ever more detailed and higher resolution monitors 00:01:28.560 --> 00:01:35.920 becoming more common and cheaper, quicker memory is also becoming more 00:01:33.200 --> 00:01:40.600 important. Graphics memory has placed an emphasis on wide bandwidth for a long 00:01:39.119 --> 00:01:47.439 time, but GDDR5X improves upon the existing GDDR5 00:01:44.720 --> 00:01:53.200 standard by allowing twice as much data to be accessed at one time, 64 bytes 00:01:51.119 --> 00:01:57.439 instead of 32. And while this may not sound like much, we should see overall 00:01:55.280 --> 00:02:04.240 transfer rates of around 10 gigabits per second or even higher per pin and nearly 00:02:00.640 --> 00:02:06.880 450 gigabytes per second of overall 00:02:04.240 --> 00:02:10.720 bandwidth while drawing less power than its predecessor. Pretty sweet. But slow 00:02:09.280 --> 00:02:17.760 down just a minute. What about that fancy new HBM that AMD came out with? 00:02:13.760 --> 00:02:19.920 Why is GDR5X a big deal then? While it's 00:02:17.760 --> 00:02:24.720 true that HBM, which you can learn more about here, has higher throughput and 00:02:22.720 --> 00:02:28.120 has a smaller footprint, which are both great things on your graphics card 00:02:26.400 --> 00:02:33.760 specifically, than GDR5X. GDR5X should be quite a bit 00:02:31.520 --> 00:02:40.239 easier, not to mention cheaper to implement than HBM since it's still 00:02:36.560 --> 00:02:42.640 quite similar to the ubiquitous GDDR5. 00:02:40.239 --> 00:02:47.360 And although both NVIDIA and AMD are heavily rumored to be moving towards HBM 00:02:45.120 --> 00:02:53.200 2.0 O for some of their upcoming architectures. GDDR5X might appear on 00:02:50.720 --> 00:02:58.000 more mid-range future graphics cards as well as the greater accessibility of 00:02:55.680 --> 00:03:02.800 high-res displays and the growing interest in virtual reality headsets 00:03:00.160 --> 00:03:08.400 will make high throughput VRAM increasingly important. Currently, GDR5X 00:03:06.640 --> 00:03:13.040 is only available on NVIDIA's new flagship, the GeForce GTX 1080, but 00:03:11.200 --> 00:03:19.040 don't be surprised to see it paired with more GPUs down the road. And whether 00:03:15.280 --> 00:03:20.800 you're going for GDDR5X or HBM, pay 00:03:19.040 --> 00:03:24.879 attention to what kind of VRAM is in your next card if you want to get into 00:03:22.640 --> 00:03:32.000 surround gaming, hook up an Oculus Rift or HTC Vive, or just really, really like 00:03:28.480 --> 00:03:34.720 things with X's in them. The MTO DSA 00:03:32.000 --> 00:03:39.200 sci-fi keycap set is available over on Massrop. It's a customizable keycap set 00:03:36.959 --> 00:03:42.879 that is set in the theme of the first person shooter game that you've never 00:03:40.799 --> 00:03:47.599 heard of, Counter Strike: Global Offensive. You'll have to pick whatever 00:03:45.519 --> 00:03:51.920 like kit and build you want to fit the layout and theme and schematic and 00:03:49.519 --> 00:03:56.319 whatnot of your keyboard, but that is very easy to do on their website and it 00:03:54.239 --> 00:04:00.239 supports tons of different layouts, even non-standard ones from various 00:03:57.920 --> 00:04:04.640 companies. So, you should be covered. You're also find even if you have like 00:04:01.760 --> 00:04:08.959 Nordic, German, UK, US layouts, all that kind of stuff. And additionally, 00:04:06.400 --> 00:04:14.000 Blizzard's Overwatch inspired novelties will be available as well. The base 00:04:11.200 --> 00:04:18.000 price is $39.99, but varies widely based on different options that are selected 00:04:15.760 --> 00:04:23.759 in the checkout as we just discussed. And we'll be launching the morning of 00:04:20.079 --> 00:04:23.759 June 13th. So go to 00:04:25.080 --> 00:04:30.479 draw.tequicky-mito and you can check all that kind of stuff out.
