Power draw in excess of 500 Watts shouldn't be an issue for anyone who is going to buy a setup like this as we expect them to have a good quality kilowatt unit installed.ĬrossFireX is really beginning to make some strides. At idle there's very little change when adding the second card. It comes as no surprise that under load the HD 5970 in CrossFire is going to start sucking down the power. We haven't added in any other cards for the simple fact that we want to clearly see the performance gains of adding the second card into the mix. In this article today we'll be simply looking at the CrossFireX configuration against the single HD 5970 to see just what kind of performance gains the setup gives us.

Looking across the bottom, you can clearly see that we have CrossFire enabled and four GPUs are up and running. With no package all we're going to be looking at the card and as you can see below, there's nothing that we didn't see with the Sapphire version of the card, albeit the lack of a sticker on top of the cooler. We'll also snag a quick GPU-Z screen shot to make sure CrossFireX is working before we simply get into the benchmarks. We'll have a quick peek at the card, just in case you haven't had a chance to see what's happening with it. Since the second card arrived from big red themselves, there isn't a whole lot to look at. For performance junkies, unless there are some real gains in this four GPU configuration, they're simply not going to be interested in the setup. We're not going to pretend we aren't excited about testing CrossFireX, nor are we going to pretend we don't expect some big numbers out of the setup.

You have to wonder what else there is to do? - We'll, that's easy install our second HD 5970 into the system and see how CrossFireX goes. crossfire has worked, and very well, granted not on ALL titles, but definitely a majority of them.So, we've looked at the HD 5970 in single form and we've also seen the massive OC potential of the card. I found the Vega crossfire was underwhelming however, imo the architecture just wasn't geared for it since even a vega gpu on it's own was struggling to be properly utilized. But by this time dx12 and vulkan were getting in most releases. initially running a pair of rx 470 cards was great, upgrading to 3x rx 580s was kicking the 1080 ti's teeth in anything dx11 and under. the GCN 1.2 clearly sorted stuff out with those cards.
However there are 3 cards out of the 200/300's that were phenominal with crossfire, i'd say the golden era of crossfire, the R9 285 Tonga and the R9 380 and 380x cards were amazing in crossfire. Crossfire tanked however on the HD7000 and r200s however, the GCN design seemed to throw a hefty wrench into the mix, basically all the R 300s were affected obviously due to the rebranding mostly. the hd6000 too since they were basically similar.
Crossfirex connector series#
The HD5000 series is the era in which crossfire really worked great. ALT+TAB back and forth was the most prevalent and often working solution, there are others that were more game specific, but pretty much any game worked with that solution if it wasn't functioning right on first loadup. Tons of games worked great, and while a lot of people think unreal engine based games, specially on the 3rd engine never worked, they did, VERY WELL, but i find it puzzling how many people didn't bother with the crossfire jumpstart fix, It was usually pretty evident when crossfire wasn't working "properly" or at all, either frame rates akin to a single gpu, or frame times that were shit due to the other gpu needing a smack in the back of the head to clock the fuck up. regardless, it was shortly after that, that the API changes kind of threw a wrench into things during the cold era of the HD2000's, though to be fair, the move to ribbon cables really was much nicer than the awkward external dongle. I'd say crossfire didn't get on it's feet until the Radeon x1900xtx cards launched, Of which i still have actually, i'm sure that mastercard could go for a premium price now. shall we say, pretty rough, understandably. There are more times where it was very functional than when it wasn't. As someone that has used every generation of amd gpu with crossfire.
