1 00:00:00,040 --> 00:00:08,200 so I could just be a total Butthead and say well I made a video about NVIDIA's 2 00:00:04,960 --> 00:00:09,800 SLI so go watch that this is the same 3 00:00:08,200 --> 00:00:16,640 except your cards from AMD and we call it Crossfire but that would be lazy and 4 00:00:13,559 --> 00:00:17,720 we strive for maximum professionalised 5 00:00:16,640 --> 00:00:21,640 around here and truthfully it's not that simple 6 00:00:20,039 --> 00:00:25,920 anyway there are some critical differences between SLI and Crossfire 7 00:00:23,760 --> 00:00:31,400 that I believe demonstrate a fundamental difference in philosophy between AMD and 8 00:00:28,760 --> 00:00:36,239 NVIDIA but first the basics both Technologies are pretty much a way to 9 00:00:33,600 --> 00:00:40,960 utilize more than one graphics card working in tandem in your PC to achieve 10 00:00:38,840 --> 00:00:46,160 nextg class performance that wouldn't otherwise be available with the current 11 00:00:43,039 --> 00:00:48,360 technology due to power thermal or other 12 00:00:46,160 --> 00:00:53,320 limitations think of it kind of like if you could buy two Xbox Ones bolt them 13 00:00:51,440 --> 00:00:59,079 together and actually run your games at 1080p burn anyway they both work with 14 00:00:56,719 --> 00:01:03,640 anywhere from two to three or even four compatible cards in one system and 15 00:01:00,879 --> 00:01:08,119 perform their best at high resolutions with graphically demanding games they 16 00:01:05,760 --> 00:01:12,759 also both dramatically increase the power consumption and heat output of 17 00:01:10,400 --> 00:01:17,759 your computer system without having a proportional impact on the performance 18 00:01:14,960 --> 00:01:21,680 you'll get in games in fact another thing they share in common is that if 19 00:01:20,079 --> 00:01:27,840 the game doesn't have a profile implemented they may not improve 20 00:01:23,400 --> 00:01:29,560 performance at all but with that said If 21 00:01:27,840 --> 00:01:35,240 you're looking for an experience that simply isn't available today by other 22 00:01:31,880 --> 00:01:37,280 means like butter smooth 4K or 1080p 23 00:01:35,240 --> 00:01:41,759 surround gaming then you're likely one of the folks that this solution was 24 00:01:39,040 --> 00:01:47,560 designed for all right so a moment ago I mentioned compatible cards this is 25 00:01:44,439 --> 00:01:50,240 differentiation Point number one for AMD 26 00:01:47,560 --> 00:01:55,040 while NVIDIA allows mix and matching of vendors and clock speeds you can SLI and 27 00:01:53,240 --> 00:01:59,920 EVGA reference card with an ASUS overclocked one they require you to use 28 00:01:58,200 --> 00:02:04,320 exactly the same Graphics process processor with the same memory 29 00:02:01,680 --> 00:02:08,679 configuration AMD on the other hand it's pretty Loosey Goosey you can mix vendors 30 00:02:06,479 --> 00:02:13,840 clock speeds RAM amounts and even the graphics processor as long as the cards 31 00:02:11,400 --> 00:02:20,480 are within the same architectural family so for example a 32 00:02:15,920 --> 00:02:22,879 7973 gig card can Crossfire with a 7950 33 00:02:20,480 --> 00:02:28,160 with 3 gig or even an r9280x with six gigs of RAM cuz they're 34 00:02:25,280 --> 00:02:33,360 all based on that same GPU differentiation Point number two for AMD 35 00:02:30,680 --> 00:02:37,800 is cost NVIDIA requires SLI certification for your cards to 36 00:02:35,080 --> 00:02:43,560 recognize your system as compatible and activate their Wonder Twin powers for 37 00:02:40,440 --> 00:02:46,120 that NVIDIA requires the qualifying PCI 38 00:02:43,560 --> 00:02:51,239 Express slots to run at 8X minimum even though these days a 4X PCI E gen 3 slot 39 00:02:49,319 --> 00:02:55,959 is plenty for pretty much any graphics card and they require the board 40 00:02:53,280 --> 00:03:00,159 manufacturer to pay a licensing fee you can find AMD Crossfire compatibility on 41 00:02:58,280 --> 00:03:04,360 product pages for like business business class boards basically anything goes as 42 00:03:02,560 --> 00:03:09,000 long as it's got a couple PCI Express 16x physical slots differentiation Point 43 00:03:07,200 --> 00:03:13,200 number three is something that's actually still a work in progress for 44 00:03:10,720 --> 00:03:18,360 AMD since the beginning of dual GPU Solutions with Voodoo SLI there's been 45 00:03:15,920 --> 00:03:24,040 some kind of connector attaching the cards with AMD r9290 series cards and 46 00:03:21,720 --> 00:03:28,920 presumably future ones as well all communication between the Cards is done 47 00:03:25,879 --> 00:03:31,120 over the PCI Express bus it's a higher 48 00:03:28,920 --> 00:03:35,360 bandwidth clean looking solution to the problem of how these cards can sync data 49 00:03:33,560 --> 00:03:39,760 with each other at high speed when they're working together finally 50 00:03:37,360 --> 00:03:44,680 differentiation Point number four is that AMD allows their cards their 51 00:03:42,080 --> 00:03:49,319 low-end cards to run in crossfire with the onboard Graphics of their apus which 52 00:03:46,760 --> 00:03:53,400 are CPUs that have strong onboard Graphics components although this 53 00:03:51,720 --> 00:03:57,599 solution still needs some work to be something that I'd really recommend and 54 00:03:55,599 --> 00:04:02,599 I guess that's it I guess that's the philosophical difference between AMD and 55 00:03:59,799 --> 00:04:07,599 NVIDIA NVIDIA locks things down which gives them tighter control over the 56 00:04:04,680 --> 00:04:12,519 consistency of the user's experience but AMD offers more flexibility and choice 57 00:04:10,640 --> 00:04:17,320 even if some of these options aren't the best thing ever at least you can pick 58 00:04:14,400 --> 00:04:22,440 them speaking of things that aren't the best thing ever searching for 59 00:04:19,160 --> 00:04:25,479

kind of serious at the beginning there the SLI video I mentioned at the very start of this one 75 00:05:25,600 --> 00:05:32,560 has some great information about dual GPU configurations in general and this 76 00:05:29,960 --> 00:05:37,759 one was more meant to augment that one with a focus on the key differences for 77 00:05:35,039 --> 00:05:41,759 AMD users anyway like and share this video if you liked it dislike it if you 78 00:05:39,639 --> 00:05:45,360 disliked it leave a comment if you have something to say to me or the rest of 79 00:05:43,280 --> 00:05:50,080 the fastest possible team and
