HIS Radeon HD 4850 Review
Categories: Graphics Cards Tags: ATI, graphics video card, his, opengl, radeon hd 4850, review
I took the time this morming to publish the test of HIS’s Radeon HD 4850 I started on month ago. I must say that Radeon HD 4850 shows high OpenGL performances and as always, vertex processing is incredibly fast (see surface deformer benchmark). At idle, GPU temperature is around 70°C while under load the temperature reaches 93°C (3-minute test with GPU Caps Viewer burner).
The full test is available here: HIS Radeon HD 4850 Graphics Card Review.

The upcoming (october 2008 version) Catalyst graphics driver is available in BETA version. You can download the huge archive (~200Mb) here:
- Catalyst 8.10 BETA for Vista
- Catalyst 8.10 BETA for XP
As soon as the WHQL version is available, I will publish the OpenGL extensions because GPU Caps Viewer told me that Cat8.10 has around 115 extensions…
Here are the screenshots of my Radeon HD 4850 and Catalyst 8.10 BETA under XP32:

Catalyst 8.9: OpenGL Extensions – Radeon HD 4850
Categories: Catalyst, OpenGL Tags: catalyst, catalyst 8.9, extension, graphics driver, opengl, opengl 3, Programming, radeon hd 4850, video card
Here is the list of OpenGL extensions supported by the Catalyst 8.9 graphics drivers for the Radeon HD 4850 under Windows XP SP2 32-bit.
The release note says Catalyst 8.9 add the phase 1 of OpenGL 3.0 support. But what does it mean? Compared to Catalyst 8.8, Catalyst 8.9 bring only 3 new extensions:
- GL_AMD_texture_texture4
- GL_EXT_blend_equation_separate (OpenGL 1.5)
- GL_EXT_depth_buffer_float
GL_EXT_depth_buffer_float has the same role than NVIDIA GL_NV_depth_buffer_float. GL_EXT_blend_equation_separate is an OpenGL 1.5 extension and GL_AMD_texture_texture4 is not documented. But most of the new OpenGL 3 extensions quoted in the release note are not present in Catalyst 8.9 under Windows XP and Vista. Maybe AMD/ATI have introduced the same principle than NVIDIA, with a kind of OpenGL 3.0 activation somewhere (see here). But here again, no documentation is available. Or more simply, AMD want to show to the community that they do an effort to support the new major version of OpenGL, but any OpenGL 3 extension is currently available to developers. Communication is a tough art at ATI!
Catalyst 8.9, like Catalyst 8.8, still slow down the GPU when FurMark is detected (see here and here for more detail).
