WEBVTT 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 00:00:04.960 --> 00:00:09.800 SLI so go watch that this is the same 00:00:08.200 --> 00:00:16.640 except your cards from AMD and we call it Crossfire but that would be lazy and 00:00:13.559 --> 00:00:17.720 we strive for maximum professionalised 00:00:16.640 --> 00:00:21.640 around here and truthfully it's not that simple 00:00:20.039 --> 00:00:25.920 anyway there are some critical differences between SLI and Crossfire 00:00:23.760 --> 00:00:31.400 that I believe demonstrate a fundamental difference in philosophy between AMD and 00:00:28.760 --> 00:00:36.239 NVIDIA but first the basics both Technologies are pretty much a way to 00:00:33.600 --> 00:00:40.960 utilize more than one graphics card working in tandem in your PC to achieve 00:00:38.840 --> 00:00:46.160 nextg class performance that wouldn't otherwise be available with the current 00:00:43.039 --> 00:00:48.360 technology due to power thermal or other 00:00:46.160 --> 00:00:53.320 limitations think of it kind of like if you could buy two Xbox Ones bolt them 00:00:51.440 --> 00:00:59.079 together and actually run your games at 1080p burn anyway they both work with 00:00:56.719 --> 00:01:03.640 anywhere from two to three or even four compatible cards in one system and 00:01:00.879 --> 00:01:08.119 perform their best at high resolutions with graphically demanding games they 00:01:05.760 --> 00:01:12.759 also both dramatically increase the power consumption and heat output of 00:01:10.400 --> 00:01:17.759 your computer system without having a proportional impact on the performance 00:01:14.960 --> 00:01:21.680 you'll get in games in fact another thing they share in common is that if 00:01:20.079 --> 00:01:27.840 the game doesn't have a profile implemented they may not improve 00:01:23.400 --> 00:01:29.560 performance at all but with that said If 00:01:27.840 --> 00:01:35.240 you're looking for an experience that simply isn't available today by other 00:01:31.880 --> 00:01:37.280 means like butter smooth 4K or 1080p 00:01:35.240 --> 00:01:41.759 surround gaming then you're likely one of the folks that this solution was 00:01:39.040 --> 00:01:47.560 designed for all right so a moment ago I mentioned compatible cards this is 00:01:44.439 --> 00:01:50.240 differentiation Point number one for AMD 00:01:47.560 --> 00:01:55.040 while NVIDIA allows mix and matching of vendors and clock speeds you can SLI and 00:01:53.240 --> 00:01:59.920 EVGA reference card with an ASUS overclocked one they require you to use 00:01:58.200 --> 00:02:04.320 exactly the same Graphics process processor with the same memory 00:02:01.680 --> 00:02:08.679 configuration AMD on the other hand it's pretty Loosey Goosey you can mix vendors 00:02:06.479 --> 00:02:13.840 clock speeds RAM amounts and even the graphics processor as long as the cards 00:02:11.400 --> 00:02:20.480 are within the same architectural family so for example a 00:02:15.920 --> 00:02:22.879 7973 gig card can Crossfire with a 7950 00:02:20.480 --> 00:02:28.160 with 3 gig or even an r9280x with six gigs of RAM cuz they're 00:02:25.280 --> 00:02:33.360 all based on that same GPU differentiation Point number two for AMD 00:02:30.680 --> 00:02:37.800 is cost NVIDIA requires SLI certification for your cards to 00:02:35.080 --> 00:02:43.560 recognize your system as compatible and activate their Wonder Twin powers for 00:02:40.440 --> 00:02:46.120 that NVIDIA requires the qualifying PCI 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 00:02:49.319 --> 00:02:55.959 is plenty for pretty much any graphics card and they require the board 00:02:53.280 --> 00:03:00.159 manufacturer to pay a licensing fee you can find AMD Crossfire compatibility on 00:02:58.280 --> 00:03:04.360 product pages for like business business class boards basically anything goes as 00:03:02.560 --> 00:03:09.000 long as it's got a couple PCI Express 16x physical slots differentiation Point 00:03:07.200 --> 00:03:13.200 number three is something that's actually still a work in progress for 00:03:10.720 --> 00:03:18.360 AMD since the beginning of dual GPU Solutions with Voodoo SLI there's been 00:03:15.920 --> 00:03:24.040 some kind of connector attaching the cards with AMD r9290 series cards and 00:03:21.720 --> 00:03:28.920 presumably future ones as well all communication between the Cards is done 00:03:25.879 --> 00:03:31.120 over the PCI Express bus it's a higher 00:03:28.920 --> 00:03:35.360 bandwidth clean looking solution to the problem of how these cards can sync data 00:03:33.560 --> 00:03:39.760 with each other at high speed when they're working together finally 00:03:37.360 --> 00:03:44.680 differentiation Point number four is that AMD allows their cards their 00:03:42.080 --> 00:03:49.319 low-end cards to run in crossfire with the onboard Graphics of their apus which 00:03:46.760 --> 00:03:53.400 are CPUs that have strong onboard Graphics components although this 00:03:51.720 --> 00:03:57.599 solution still needs some work to be something that I'd really recommend and 00:03:55.599 --> 00:04:02.599 I guess that's it I guess that's the philosophical difference between AMD and 00:03:59.799 --> 00:04:07.599 NVIDIA NVIDIA locks things down which gives them tighter control over the 00:04:04.680 --> 00:04:12.519 consistency of the user's experience but AMD offers more flexibility and choice 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 00:04:14.400 --> 00:04:22.440 them speaking of things that aren't the best thing ever searching for 00:04:19.160 --> 00:04:25.479 royaltyfree images and videos to use in 00:04:22.440 --> 00:04:27.160 your projects we used to waste a ton of 00:04:25.479 --> 00:04:31.600 time trying to find images

the beginning there the SLI video I mentioned at the very start of this one 00:05:25.600 --> 00:05:32.560 has some great information about dual GPU configurations in general and this 00:05:29.960 --> 00:05:37.759 one was more meant to augment that one with a focus on the key differences for 00:05:35.039 --> 00:05:41.759 AMD users anyway like and share this video if you liked it dislike it if you 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 00:05:43.280 --> 00:05:50.080 the fastest possible team and as always don't forget to
