so the purpose of today's video is going to be to evaluate quad crossfire with dual Radeon 69 90s which you can see on my bench right now against Quad SLI with dual dual dual dual GTX 590 so those are about to go on the bench so I'm going to be using a different test platform from what I normally use this is a gigabyte g1 sniper motherboard and it is running with an Intel Core i7 980 X at 4.2 6 gigahertz or something like that so I'm well over 4 gigahertz I have 12 gigs a ddr3 1600 RAM I am using a different power supply as well but I bought my regular testing hard drive and then because my external drive broke I'm using a WD green drive for my steam file so that is the test bench I will be using to determine which of these configurations runs better you may have noticed already that it's a little on the warm side no not warm side it's a little on the loud side the reason for that is that you can see these rubber spacers that come on the 6990 S here yep now you can get that is to give it si you can see at the bottom it's very close together at the top it's slightly separated that gives it a little bit of a gap for that fan to intake air but it still has to work pretty hard to cool those two GPUs so it is a little on the loud side here you can see my Lost Planet 2 results I'm going to be comparing the quad crossfire against the Quad SLI and then if I have time I will also run individual 6992 X 590 numbers to compare against their dual graphics equivalents although that it's not equivalent at all so I've got most of my testing done I'm just running a Lost Planet 2 bench on the GTX 590 Quad SLI configuration so I've note about this particular video is the fact that I will be using a higher resolution than normal you can see my 1920 by 1080 monitor is actually back they're behind my 30-inch 2560 by 1600 monitor also because we are using very high end GPU configurations I will be using higher anti aliasing anisotropic filtering settings and I normally do so I'll be cranking up as high as they go for all of the games in my testing suite which will be Battlefield Bad Company 2 Crysis 2 metro 2033 and Lost Planet 2 so for the first three games I'll be doing my own custom run throughs recorded with fraps and for Lost Planet 2 amusing test B you can see here I have the GTX 590 s on the test bench they're not nearly as loud this is 69 90s although they do get toasty and they do get loud running in a configuration like this especially that top card although you can see the spacing is significantly more than we were seeing previously with our other config connection see all the way through it and both cards are able to sit straight in their slots you may ask why I chose to use the slots that are right next to each other on this board versus this one right here and the reason as you can see in the PCIe slot there is that this bottom slot is only wired for 8x so if I were to use these to high-end GPUs in the top and the bottom PCIe 16x slots on the g1 sniper I'd be running them at 16x + 8 X mode respectively and based on my recent testing with PCIe bandwidth I felt that was not really appropriate so I would have liked to use the 2 16 X slots which is what I've decided to do here so I will be back with the results once I'm finished running my single GTX 590 tests alright guys so I'm using the latest drivers available at the time of filming and benchmarking which is all on the same night tonight and here are the settings that I was using so Crysis 2 is obviously at maximum so the game that scaled the best out of the ones in my test suite was obviously Battlefield Bad Company 2 the 69 90s um actually scale more than a hundred percent which makes no sense but we'll just consider that within the margin of error and we'll call it a hundred percent scaling and then for the five 90s we saw almost 100% scaling something like ninety percent scaling so excellent scaling on that particular game 590 scale very very well in crisis to 6990 besides the flickering bug which made the game pretty much unplayable also didn't scale very well Ambu has some work to do on the crisis to performance of their 6990 but I'm sure that's something they'll resolve with a driver issue in the future Metro 2033 6990 scaled quite well adding another 50% performance to itself as well as the 590 590 actually scaled quite well as well but still fall short of the quad crossfire setup in terms of overall performance on Lost Planet 2 we see very poor scaling across the board and the 590 SLI beetle crossfire as well as on Battlefield Bad Company 2 the 590 Quad SLI wins so basically the objective today was not to determine a clear winner it was more to look at the state of quad GPU gaming as a whole I'm not going to say who but I will actually okay I've got blue screens with both solutions during my testing among other sort of random issues that did crop up so I'd go as far as to say that there's definitely some work to do on the drivers for both of these cards and but once that's resolved they definitely deliver some crazy performance numbers in the right scenarios remember these are all benchmarked at 2560 by 1600 so we're looking at that'll feel bad company 2 numbers well over 100 fps
