Radeon HD 4870 X2: Four Cards Compared

Comparison Of Graphic Chips And Test Configurations

HIS and Sapphire sent Radeon HD 4870 X2 cards set to reference clock rates—any additional overclocking was performed in our own lab. All settings were set via the AMD graphics driver. As a baseline for analysis, the HIS card was tested with both normal frequencies and overclocked. All models with increased frequencies are marked “OC.”

When we started benchmarking for this project, we were using the most current drivers for this test, Catalyst 8.10 from AMD and Nvidia’s beta driver 180.42. On the following page, we will talk about the difficulties and problems we noticed with Catalyst 8.10. The Nvidia beta driver is stable with single cards and the Intel chipset (X38), but with SLI on the nForce 780i, we sometimes experienced problems in Assassin’s Creed and Mass Effect causing the whole system to freeze. As far as performance is concerned, the latest Catalyst 8.11 drivers improve frame rates in Far Cry 2 and Stalker: Clear Sky, according to AMD.

The standard CPU for our graphic card charts is an X6800 Extreme Edition running at 2.93 GHz, which is comparable to an E6750 or E8200. For this high-performance test we used a quad-core CPU, which runs at 3.67 GHz, overclocked using the multiplier with settings of 11x333 MHz. If you’ve read the article Wake 3D Power Wake-up, you already know all the steps we took: in order to find the highest overall result, the fastest double chip card should get the fastest CPU partner. We had to choose between an E8500 at 3.8 GHz and the over clocked quad core CPU with 3.67 GHz; the latter turned out to be faster by 3.5%.

Not only do we have four super-fast Radeon HD 4870 X2s to test, but also a list of 31 other graphics configurations including CrossFire and SLI setups. If you're in the market for AMD's fastest card available, you'll want to see this.

"Because of accessories and price, Sapphire is our best-buy recommendation."
One slight warning about sapphire though. If you have problems, don't expect their support team to help you before you've solved the problem yourself!

I made a ticket regarding some issues with my 4870 on august 7th, and received a reply on the 26th of september! That's 46 days to address an error they simply stated would go away with a bios upgrade from their homepage!

As for the article, I actually liked the detailed driver errors they encountered. Not that I liked the errors themselves, but I liked them being explained. Usually you just read 'after spending some hours resolving driver errors ....' without getting any wiser.

Wow, AMD cards consume power like a Detroit SUV. I like Nvidia GTX 2xx series’ Toyota Prius like efficiency at idle.

Why didnt they use the GTX260 Core 216? its like way better than the regular GTX260. And i just read yesterday that Nvidia was only going to make GTX260 Core 216 now. http://www.fudzilla.com/index.php?option=com_content&task=view&id=10497&Itemid=1

Why didn't they try using core i7 (extreme maybe)

Hmm your right. Power house vs crippled mouse.. yeah your analagy sucked im sure mine did to but all i saw from what you typed was i like weak stuff dont give me more power.

seems to me if you are going to be comparing the highest end cards and even crossfire them for 4x you would have the highest resolution as one of the options. i would think people considering going x2 in crossfire would consider a 30" screen.

don't get me wrong, i liked the article but would have liked to have seen the resolution spectrum hit the top.

It's nice to see the 9800GX2 included in the tests. I was considering the 4870x2 due to all the rave reviews but they never had the comparison like this against my current 9800GX2. I won't be getting new card anytime soon it seems. Thanks.
