A guys dream come true, doing two of 'em !
Company: ATi technologies
Price: ~1050 USD
Hello everyone, and welcome to Guru3D.com's most delayed article ever. Yes, this article should have been posted early February where as now it's almost April *coughs*. Today we'll bring you a long awaited review on ATI's Radeon X1900 XT Crossfire as supplied by ASUS. Now briefly let me tell you what happened over the past couple of weeks.
First we had issues allocating an RD580 mainboard. Once we did allocate one we had an issue allocating another X1900 for our review. Once we allocated one we found out that there was a nasty BIOS issue with the RD580 mainboard. Once that was fixed we uncovered that *drum roll* our RD580 mainboard was broken.
So regretful .. not my style but hey this delay .. it really wasn't my fault you know ! Anyway, without further ado let me present you the products used in today's review as that well known manufacturer ASUS had a big part in today's article. To be able to handle all that luxurious rendering power ASUS supplied us with their all new ATI RD580 based A8R32-MVP Deluxe and an ASUS EAX X1900 Crossfire edition graphics card. We'll pair that card up to our reference card which is the fantastic ATI Radeon X1900 XTX 512MB.
But first things first, to the few that don't know it let me explain what terms such as SLi and Crossfire actually mean.
NVIDIA's SLI has been the company's best promotional idea since 2004. ATI on their end simply had to offer a rather bloodthirsty counter reaction which of course resulted into Crossfire. What do both solutions offer ? Two graphics cards rendering these little software applications that we call games. Why two graphics cards ? There's a number of reasons actually. It's cool, flashy, a nice experience when playing games but mostly ...it's annoying that you constantly have to upgrade your graphics card each year. Technology is moving so fast plus, well, let's face it .. the graphics chip/card manufacturers really love the fact that you need to buy a card each year. So a good alternative without spending too much money is to add a second similar generation graphics card to the one you already have in your PC and effectively double your brute rendering gaming performance. This is the concept that is ATI Crossfire. You take two similar graphics cards that you connect to each other and double up that horsepower in your PC.
There are some disadvantages .. the biggest one being your wallet as it is an incredibly expensive solution if you decide to buy the two cards at once. Next to that you'd be wise to buy a Crossfire ready mainboard or a mainboard with two x16 PCI-Express slots. Now let me sidetrack a little, here's a big advantage for ATI over NVIDIA, they do not force you the requirement of sticking to an ATI chipset based solution. Intel's 975i chipset for example can work fine also with the upcoming Catalyst 6.5 drivers (released early May).
What'll also make Crossfire expensive is the fact that you need a serious processor to be able to handle that brute force, you need a power supply that can handle all these components and you need to invest in two graphics cards. So all in all that is a rather hard struggle. It, however, is an extremely fun struggle though.
What we'll be doing today is this: We took a Crossfire mainboard (ASUS A8R32-MVP Deluxe) and started to configure it precisely the same as our main SLi graphics cards test PC to get you guys a nice overview of what Crossfire can do.
Guru's ... let the games commence !
Today's tested product is the shaggy Radeon X1950 Pro which comes with the newer IceQ3 cooling solution; a review on ATI's latest 12-pipe mid-range product which obviously was based off the R580 silicon, and is quite frankly a very credible graphics card as you'll learn in this article. The card features 36 Pixel Shaders units. And for roughly $219-239 you can pickup the 256MB version already.
Radeon X1650 XT & X1950 Pro & Crossfire
Primarily this is a Radeon X1650 XT Crossfire article, yet with included X1950 Pro Crossfire results as well. Ever since NVIDIA released the GeForce 7600 GS/GT cards earlier this year ATI has had a very rough time delivering a product that offers the same performance. They constantly were close but not close enough. ATI worked hard to finish up its new 80 nanometer products and despite a delay of all the 80 nanometer chips, it is finally ready in good quantities. The Radeon X1950 Pro for example is such a product.
HiS Radeon X1650 PRO review
The Radeon X1650 Pro utilizes the ATI RV535 graphics core, a new revision of the RV530 which was the basis of the X1600 series. What's new then you are asking ? Uhm, well nothing except a newer 80nm fabrication process. That 80nm process ensures cheaper production of the silicon and more importantly less heat and likely lower graphics core voltages. That means you can clock the core faster, which was done quite insignificantly for this model but the increase is there.
Radeon X1950 Pro 512MB Review
So today we'll be looking at the rather lovely Radeon X1950 Pro from this company, a review on ATI's latest 12-pipe mid-range product which obviously was based off the R580 silicon, and quite frankly is a very credible graphics card as you'll learn in this article. The card features 36 Pixel Shaders units. For $199 you can pickup the 256MB version already, it sounds like a great deal as it should offer at least twice the performance of a X1600 Pro.
