Asus Extreme Radeon HD 4850 review

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.

Naixela released two demos “geometry shader painterly rendering” and “geometry shader tessellation” taking advantage of Shader Model 4 (inclusive source code).

- Geometry Shader Painterly Rendering Demo
Renders a scene into color, position, and normal textures, and then outputs the scene as a large number of brush strokes covering the screen using the geometry shader.

- Geometry Shader Tessellation Demo
Tessellates a heightfield based on distance to the viewer using the geometry shader.

How to run OpenGL programs broken by ATI Catalyst 7.12+

Be the first to comment - What do you think?  Posted by JeGX - at 09:53

Categories: Catalyst   Tags: , ,

In December 2007, ATI removed 22 extensions from OpenGL in Catalyst 7.12. Unsurprisingly this mashed a bunch of applications. A workaround is to put a copy of atioglxx.dll 7.11 into folders of applications that stopped working.

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 refines its approach to Stream Computing

Be the first to comment - What do you think?  Posted by JeGX - 2008/06/20 at 17:13

Categories: Programming   Tags: , , , ,

Just like Nvidia, AMD provides developers with a high-level application programming interface (API) to tap into its latest graphics processors for non-graphics compute applications. Unlike Nvidia, though, AMD doesn’t make very much noise about what it’s doing in that area. Curious, the guys at The Tech Report got on the phone with AMD Stream Computing Director Patti Harrell and asked her to shed a little light on AMD’s Stream Computing initiative.

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.

Read the full review HERE

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.
