Core i7: 4-Way CrossFire, 3-way SLI, Paradise?
Hardware Enthusiast’s Paradise
If you’re a fan of high-end hardware, insane graphics configurations, and equatorial heat, you’re going to love the platforms we set up in order to test Core i7’s gaming alacrity.
We’ve lined up the three fastest desktop platforms currently available—Intel’s Core i7 965 Extreme, Intel’s Core 2 Extreme QX9770, and AMD’s Phenom X4 9950. As we know, Core i7’s X58 chipset supports CrossFireX and SLI, so one board is able to yield numbers for all of our graphics configurations with this CPU. We used X48 for CrossFireX and Core 2 Extreme, swapping out for nForce 790i SLI Ultra when it came time to test SLI and Core 2 Extreme. The Phenom X4 setup supports CrossFireX-only, so our numbers were drawn from AMD’s 790FX/SB750 chipset combination. To each of these setups we applied a range of graphics subsystems.
- X58 (Core i7 Extreme): 1/2/3-way SLI using GeForce GTX 280s and 1/2/4-way CrossFireX using a single Radeon HD 4870 and two Radeon HD 4870 X2s
- X48 (Core 2 Extreme): 1/2/4-way CrossFireX using a single Radeon HD 4870 and two Radeon HD 4870 X2s
- 790i SLI Ultra (Core 2 Extreme): 1/2/3-way SLI using GeForce GTX 280s
- 790FX (Phenom X4): 1/2/4-way CrossFireX using a single Radeon HD 4870 and two Radeon HD 4870 X2s

DFGum Yep, i hafta say being able to switch brands of graphics cards on a whim and selling off the old is great. Knowing im going to be getting the preformance these cards are capable of (better price to preformance ratio) is nice also.Reply -
cangelini randomizerSLI scales so nicely on X58.Reply
Hey you even got a "First" in there Randomizer! -
randomizer cangeliniHey you even got a "First" in there Randomizer!And modest old me didn't even mention it. :lol:Reply -
enewmen Still waiting for the 4870 X2s to be used in these bechmarks. I thought THG got a couple for the $4500 exteme system. But still happy to see articles like this so early!Reply -

Go check out the benchmark pages man! Every one with 1, 2, 4 4870s. The 2x and 4x configs are achieved with X2s, too.
Oh, and latest drivers all around, too. Crazy, I know! =) -
enewmen cangeliniI found it, just read the article too quickly. - My bad.Reply
"A single Radeon HD 4870 X2—representing our 2 x Radeon HD 4870 scores—is similarly capable of scaling fan speed on its own. "
Hope to see driver updates like you said. -
spyde Hi there, my question regarding these benchmarks with the HD card is, "was a 2G card use or a 1G". I am about to buy a new system and was looking to buy 2 x HD4870X2 2G cards, but with these results its looking a bit ify. I hope you can answer my question.Reply
Cheers. -
Proximon That's a nice article. I especially like the way the graphs are done. everything is scaled right, and you get an accurate representation.Reply
