Radeon HD5770 CrossFireX Performance

This article is all about answering one question: how well does the Radeon HD 5770 scale in CrossFireX. Benchmark Reviews has already investigated and published reviews for two video cards based on the HD5770 "Juniper" chip; an engineering sample from ATI and a production card from XFX. They both acquitted themselves quite well, and we included some CrossFireX test results in the XFX review, using two cards strapped together on an Intel P45 platform. This time we take a look at how 1, 2, and 3 cards work together on our new Windows 7 test suite, with an AMD 790FX motherboard.

Looking at our earlier reviews of the Radeon HD5770, we already know that two of them in CrossFireX soundly beat a single NVIDIA GTX285. So, this article is not about comparing the 5770 to other cards; we've already done that. What we're interested in is how well CrossFireX works once you get past the initial surge of dual cards. Is adding a third card a waste of time, or is it just as effective as adding the second card?

Stick around, as we test out all three configurations on a series of eight challenging benchmarking tools. I can promise you a few surprises.

About the company: ATIATI_Radeon_Logo_300.jpg

Over the course of AMD's four decades in business, silicon and software have become the steel and plastic of the worldwide digital economy. Technology companies have become global pacesetters, making technical advances at a prodigious rate - always driving the industry to deliver more and more, faster and faster.

However, "technology for technology's sake" is not the way we do business at AMD. Our history is marked by a commitment to innovation that's truly useful for customers - putting the real needs of people ahead of technical one-upmanship. AMD founder Jerry Sanders has always maintained that "customers should come first, at every stage of a company's activities."

We believe our company history bears that out.

# TV is max 1080pBruceBruce 2010-11-27 20:57
I don't know of any Sony Bravia TVs that will display 1920 x 1200. The newest ones will max out at 1920 x 1080. If you have the video card trying to drive this TV with 1920 x 1200, either the TV or the video card is probably freaking out. Try setting the video resolution to 1920 x 1080 if you have one of the newer 1080p TVs. If it's am older unit it's 720P and 1366 x 768 pixels.

Ronald ren i have the xfx video cards running in xfire and the same msi motherboard and a 600watt ocz PSU, and i too have the same issue. No matter what game i am running (is playable in crossfire) it seems i get slower performance in crossfire and my single radeon 5770 runs faster. i know with t that mobo it is a 16x lane but when ran in crossfirex it will make the cards 8x X 8x in their respective lanes. Have you ever resolved the issue? I can't figure it out.
