Futuremark 3DMark Vantage
3DMark Vantage is an updated and more demanding evolution over the package that it succeeded. Our tests cover the "Performance" setting of the benchmark. The application will output three scores. The first two are CPU and GPU scores, which are formed from various tests that will focus on either of the two (or both). On the basis of those scores, a final "Overall" score is then outputted with a "P" prefix beforehand to denote that the "Performance" setting was applied.
The results are quite interesting, showing the HD 4890 crossfire setup sitting in between a single HD 5870 and the HD 5870 Crossfire score. At any rate, the previous generation isn't struggling to hold it's own. It should be mentioned however that the end result of a synthetic benchmark does not always translate to similar outcomes in real games, so on that bomb shell let's have a play with...
Crysis Warhead is without a doubt one hard nut to crack, especially at higher resolutions and a dash of Anti Aliasing and Anisotrophic Filtering. Typically, this game is heavy on both CPU and GPU however the limitation at high resolutions skews the dependancy towards the latter. Depending on how well the drivers are optimised, Multi GPU scaling could vary greatly. But anyway, given the game's "tough" characteristics, we were eager to find out the end result.
Wow. Dare I say it? Has Crysis Warhead been defeated? Thanks to superb crossfire scaling, there was not even so much as a stutter even in denser scenery with plenty of explosions. Quite notably, the HD 4890 CrossfireX setup performs about as fast as a single HD 5870 and two of the latter offers considerable increases on top of that.
Far Cry 2
Far Cry 2, a slightly older hit but based on a fairly demanding engine also has a fair level of GPU dependancy at least particularly so at higher resolutions. This particular game features a fabulous benchmarking tool, which loops an intensive Far Cry 2 scene and gatherers minimum, maximum and average framerates accordingly. This allows for a more accurate comparison from one test item to another. As mentioned, we have set all Quality Settings to the highest possible within the tool.
Once again, CrossfireX scaling appears to be very reasonable. Far Cry 2 however doesn't appear to require it's horsepower in this particular scenario. Perhaps it may be of interest for 2560x1600 users?
Microsoft Flight Simulator X
Microsoft Flight Simulator X is part of a handful of games that are heavily CPU reliant. If you thought that this was bad, at initial release this game did not have multicore cpu support. I need not say anymore on that front, but with this in mind, the results that followed were not too surprising.
So if you're a Flight Simmer, do yourself a favour and opt for a single card solution and spend some of your savings on overclocking that Core i7 of yours to 4.0GHz and beyond
Call of Duty 4
Call of Duty 4 is one of the older games within our testing. Once again, all quality settings are set as high as possible and Dual Graphics Card support has been checked in game. Our particular CoD4 test is not terribly strenuous but the performance scaling is quite clear.
