VisionTek Radeon HD 4870 X2 2GB Linux Review

Phoronix has tested VisionTek’s Radeon HD 4870 X2 2GB under Ubuntu 8.04.1 32-bit with the Linux 2.6.24 kernel and the latest ATI Catalyst 8.8. Catalyst 8.8 for Linux supports CrossFire, OverDrive overclocking, adaptive anti-aliasing, and other improvements. The benchmark suite used by Phoronix includes OpenGL titles like Doom 3, Quake 4, Enemy Territory: Quake Wars and the Phoronix Test Suite.

The conclusion of this test is the Radeon HD 4870 X2 isn’t quite as far as two Radeon HD 4870 512MB graphics cards linked together via CrossFire, but it’s darn close.

Best Video Cards For The Money: August 2008

If time is money, this article will save money your money: if you don’t have the time to research among the huge amount of reviews and benchmarks across the web, or if you don’t feel confident enough in your ability to make the right decision, this guide is for you.

Tom’s Hardware Guide has come to your aid with a simple list of the best gaming cards offered for the money:

For example in the range of 350$ to 500$, Tom’s Hardware recommends 2 radeon HD 4850 in Crossfire instead of one GeForce GTX 280. But if you have already a SLI motherboard, the best choice is 2 GeForce 9800 GTX in SLI.

Octa Crossfire with eight GPUs soon?

In AMD/ATI laboratory test, four Radeon HD 4870 X2 have been combined. But AMD will not release any drivers for such an Octa Crossfire bundle. In consideration of a motherboard that would have to be able to bear four dual slot graphics cards and the required scaling, Octa Crossfire should be seen as nothing more than a technical gimmick.

Radeon HD 4850 and 4870 CrossfireX Performance Test

Since Radeon series 4800 cards offer so much value, it might even be interesting to pair them in CrossfireX mode. AMDs ATI solution can be paired and matched as well. So today Guru3D has placed several cards together in CrossfireX mode.

No kidding it is sick how much performance these cards combined can push, the 2-way GPU scaling is just really superb. Crossfire with two series 4800 cards definitely makes more sense than NVIDIA’s high-end SLI money wise.

Six Months with ATI CrossFireX Technology

Eighteen months ago when nVidia’s GeForce 8800 GTX was king of the hill, a multi-GPU setup was either ostentatious and reserved only for the most die hard gamer if you were using a high-end card, or downright silly if you were pairing up midrange and lower. NVIDIA’s SLi initiative, started back with the GeForce 6 series, was basically a kludge designed to wring that last ounce of performance out of the cards of the era for the deep-pocketed enthusiasts. ATI’s CrossFire, when it debuted up until the release of the Radeon X1950 Pro, was an embarassment, offering poorer performance and compatibility than NVIDIA’s solution.

Four Radeon HD 4850s In CrossfireX

TweakTown has tested four Radeon HD 4850 in CrossfireX on the trusty 4GHz QX9650.

Read the review HERE.

Two cards really is the sweet spot for HD 4850s at the moment; we see some good gains over a single card and the cost is still relatively low compared to the competition.

AMD have a winner on their hands with the HD 4850; just don’t expect to see the same value for money as you start climbing the ranks with three or four cards. It could still be a while before we see these kinds of setups represent any form of value for money, much like NVIDIA with their Tri SLI GTX 280 setup.

AMD Radeon HD 4850 Crossfire

Guru3D has reviewed the new product of ATI, the Radeon HD 4850. Two graphics cards makers are in the spotlight: Force3D and PowerColor.

The Radeon 4850 features 800 shader processors, 40 textures units and a 55nm fabrication process.

The Verdict

At 199 USD this is just a bitching nice product. By releasing the Radeon HD 4850 not only you get a very feature packed and stuffed product,
you’ll also purchase a product that is competing with a GeForce 9800 GTX really well.

At this very moment, I’d pick up the Radeon HD 4850 for several reasons though. One of them is DX 10.1 support, the second one is slightly
(on average) better performance.

Back to the 4850 then, not everything about it is perfect though, sorry. The temperatures this card reaches are not really fun to observe,
80-85 Degrees C is normal for this card. Heat is dumped inside the PC due to the single slot cooler, and it certainly dumps a lot of heat.
