ATI Radeon HD 4850 Linux Performance

The chaps overs at Phoronix have analyzed the performance of the Radeon HD 4850 under Linux.

Read the complete article HERE.

While the ATI Radeon HD 4800 series was greeted with same-day Linux support, this first-cut Linux support clearly isn’t as well optimized as the Windows driver.
Alternatively, to this point they may have spent all of their resources tuning the DirectX performance and have forgone tuning the OpenGL side.

What’s the explanation for the Radeon HD 4850 on Linux falling so far behind their competitors? According to AMD engineers the Linux driver has yet to be well optimized.

Radeon HD 4870


Radeon HD 4850

FurMark has been used to stress Radeon HD 4870 and 4850′s GPUs.

Final words
So, numbers can talk for itself. With the price tag $199(HD 4850) and $299 (HD 4870), RV770 is the BEST bang for the buck. Compare to GTX 260, A $299 only HD 4870 is a smarter choice. Yes, using this kind of word seems quite biased, but if you read all numbers from our review you will see my point.

Compare to GTX 260, HD 4870 is only 3/4 of its price while test items show the card have almost the same firepower!

HD 4850’s rival is 9800GTX, and we can see while their price keeps the same, HD 4850 have more than 15% leading.

TechSpot has published a review about ASUS’s Radeon HD 4850 Extreme.

Read the review HERE.

Final Thoughts
Overall the Radeon HD 4850 has proven to be a real winner, and possibly one the best $200 graphics cards we have ever reviewed. The power consumption levels are excellent, performance was amazing, and hopefully with some decent cooling the overclocking will improve as well.


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.
