1 00:00:00,080 --> 00:00:07,919 When NVIDIA announced that its new Pascal consumer GPUs wouldn't be using 2 00:00:04,640 --> 00:00:10,480 HBM2 video memory, some folks were left 3 00:00:07,919 --> 00:00:15,120 feeling a little confused. However, that isn't to say that they didn't change 4 00:00:12,160 --> 00:00:22,080 anything about their VRAM, as these cards are using the also newly released 5 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 6 00:00:24,400 --> 00:00:32,680 its name, which might be trying to remind people of words like exciting, 7 00:00:30,279 --> 00:00:37,520 extreme, or expensive? Well, that might depend on 8 00:00:34,960 --> 00:00:43,680 who you buy your components from. So, instead, let's talk about what GDDR5X 9 00:00:40,640 --> 00:00:45,840 actually is. It's a type of video RAM 10 00:00:43,680 --> 00:00:51,200 which does things like hold textures, store images in frame buffers, provide 11 00:00:48,320 --> 00:00:55,440 the GPU with lighting information. In short, it holds the data that your GPU 12 00:00:53,120 --> 00:00:59,920 actually has to process so that your computer will display your game 13 00:00:57,440 --> 00:01:04,080 properly. But the arisen question is what's special about GDR5X in 14 00:01:02,160 --> 00:01:08,640 particular, and is it going to make your games look any better or run faster? 15 00:01:06,240 --> 00:01:12,240 Well, usually VRAM tends to matter more the higher the resolution your games are 16 00:01:10,560 --> 00:01:16,799 running at, making it especially important for multimonitor setups or if 17 00:01:15,040 --> 00:01:22,000 you're trying to run things with aggressive anti-aliasing or high-res 18 00:01:19,840 --> 00:01:26,560 texture settings. As these things require more stuff to be held in memory. 19 00:01:24,799 --> 00:01:31,040 And with games becoming ever more detailed and higher resolution monitors 20 00:01:28,560 --> 00:01:35,920 becoming more common and cheaper, quicker memory is also becoming more 21 00:01:33,200 --> 00:01:40,600 important. Graphics memory has placed an emphasis on wide bandwidth for a long 22 00:01:39,119 --> 00:01:47,439 time, but GDDR5X improves upon the existing GDDR5 23 00:01:44,720 --> 00:01:53,200 standard by allowing twice as much data to be accessed at one time, 64 bytes 24 00:01:51,119 --> 00:01:57,439 instead of 32. And while this may not sound like much, we should see overall 25 00:01:55,280 --> 00:02:04,240 transfer rates of around 10 gigabits per second or even higher per pin and nearly 26 00:02:00,640 --> 00:02:06,880 450 gigabytes per second of overall 27 00:02:04,240 --> 00:02:10,720 bandwidth while drawing less power than its predecessor. Pretty sweet. But slow 28 00:02:09,280 --> 00:02:17,760 down just a minute. What about that fancy new HBM that AMD came out with? 29 00:02:13,760 --> 00:02:19,920 Why is GDR5X a big deal then? While it's 30 00:02:17,760 --> 00:02:24,720 true that HBM, which you can learn more about here, has higher throughput and 31 00:02:22,720 --> 00:02:28,120 has a smaller footprint, which are both great things on your graphics card 32 00:02:26,400 --> 00:02:33,760 specifically, than GDR5X. GDR5X should be quite a bit 33 00:02:31,520 --> 00:02:40,239 easier, not to mention cheaper to implement than HBM since it's still 34 00:02:36,560 --> 00:02:42,640 quite similar to the ubiquitous GDDR5. 35 00:02:40,239 --> 00:02:47,360 And although both NVIDIA and AMD are heavily rumored to be moving towards HBM 36 00:02:45,120 --> 00:02:53,200 2.0 O for some of their upcoming architectures. GDDR5X might appear on 37 00:02:50,720 --> 00:02:58,000 more mid-range future graphics cards as well as the greater accessibility of 38 00:02:55,680 --> 00:03:02,800 high-res displays and the growing interest in virtual reality headsets 39 00:03:00,160 --> 00:03:08,400 will make high throughput VRAM increasingly important. Currently, GDR5X 40 00:03:06,640 --> 00:03:13,040 is only available on NVIDIA's new flagship, the GeForce GTX 1080, but 41 00:03:11,200 --> 00:03:19,040 don't be surprised to see it paired with more GPUs down the road. And whether 42 00:03:15,280 --> 00:03:20,800 you're going for GDDR5X or HBM, pay 43 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 44 00:03:22,640 --> 00:03:32,000 surround gaming, hook up an Oculus Rift or HTC Vive, or just really, really like 45 00:03:28,480 --> 00:03:34,720 things with X's in them. The MTO DSA 46 00:03:32,000 --> 00:03:39,200 sci-fi keycap set is available over on Massrop. It's a customizable keycap set 47 00:03:36,959 --> 00:03:42,879 that is set in the theme of the first person shooter game that you've never 48 00:03:40,799 --> 00:03:47,599 heard of, Counter Strike: Global Offensive. You'll have to pick whatever 49 00:03:45,519 --> 00:03:51,920 like kit and build you want to fit the layout and theme and schematic and 50 00:03:49,519 --> 00:03:56,319 whatnot of your keyboard, but that is very easy to do on their website and it 51 00:03:54,239 --> 00:04:00,239 supports tons of different layouts, even non-standard ones from various 52 00:03:57,920 --> 00:04:04,640 companies. So, you should be covered. You're also find even if you have like 53 00:04:01,760 --> 00:04:08,959 Nordic, German, UK, US layouts, all that kind of stuff. And additionally, 54 00:04:06,400 --> 00:04:14,000 Blizzard's Overwatch inspired novelties will be available as well. The base 55 00:04:11,200 --> 00:04:18,000 price is $39.99, but varies widely based on different options that are selected 56 00:04:15,760 --> 00:04:23,759 in the checkout as we just discussed. And we'll be launching the morning of 57 00:04:20,079 --> 00:04:23,759 June 13th. So go to 58 00:04:25,080 --> 00:04:30,479 draw.tequicky-mito and you can check all that kind of stuff out.
