ATI Radeon HD 4550: a $50 DirectX 10.1 Graphics Card

The Radeon HD 4550 is the level entry graphics card fron AMD/ATI. As the benchamrks show it, this card is not powerful for 3D gaming but is perfect for HTPC. The price is around US$50.-.

Radeon HD 4550 main specifications
– GPU: RV710 / 600MHz / 55nm
– Shader Processors: 80
– Texture Units: 8
– ROPs: 4
– Transistors: 242M
– Memory: 512M or 256M GDDR3 / 800Mhz / 64-bit
– DirectX 10.1 and OpenGL 2.1

Ray-tracing the way to go for game developers?

TG Daily has interviewed Daniel Pohl, an engineer who is making some impressive progress in ray-tracing research, about Intel’s ray-tracing efforts.

Q: What is Larrabee from your perspective. What is the underlying architecture and the programming model?
A: Larrabee was primarily built as a rasterizering processor. Therefore you have support for DirectX and OpenGL. But it will also be a freely programmable x86-architecture. That means you could, for example, write your own rasterizer with your own API, a ray tracer, a voxel renderer or combinations of those. You could also use it for non-graphical applications that benefit from parallelization.

Q: What API is Intel using to showcase ray tracing demos?
A: We wrote our own API. The shading system uses a HLSL-like syntax that allows you also to shoot new rays within a shader. Using that API the programmer has no need to manually multi-thread the rendering and does not need to optimize the shading with SSE as this is done by the shading compiler automatically.

Valve’s Source Engine Coming To Linux

There have been rumors since last year that Valve may be serious about porting Source games to Linux after Valve Software began seeking a senior software engineer with the responsibility of porting Windows-based games to the Linux platform. Valve Software has yet to officially announce Linux clients for any of its software, but at Phoronix we have received information confirming that Valve is indeed porting its very popular Source engine to the Linux platform.

Currently, the Source Engine uses Microsoft’s DirectX API (support for version 8.1, 9.0, and 10.0 with Source Engine 2007).
The Source Engine is designed to be highly modular, and this is hopefully how the OpenGL support will be introduced, which is needed for any Linux or Mac OS X support. The Source Engine does contain technological enhancements such as High Dynamic Range (HDR) rendering, a soft-particle system, an advanced AI system, and its physics capabilities originate from Havok 2.

Demoscene: Realtime Generation

Here is a nice prod from Smash (Fairlight) and Navis (ASD). This is a DirectX 9 prod and it requires a fast PS 3.0 graphics card.

Voici une belle petite production de deux pilliers de la demoscene, Smash (Fairlight) and Navis (ASD). C’est une démo DirectX9 et elle demande une carte graphique très véloce surtout avec les pixel shaders en version 3.0.

3DMark Vantage

3DMark Vantage le nouveau benchmark CPU/GPU de Futurmark est disponible depuis quelques heures sur les serveurs des sites 3D majeurs comme Guru3D. 3DMark Vantage est ciblé pour Windows Vista et DirectX 10 et utilise un tout nouveau moteur 3D pour exploiter au mieux la dernière API graphique de Microsoft.

Ce nouveau benchmark est disponible en 4 versions: une gratuite (trial) et 3 payantes:
– Basic: $6.95
– Advanced: $19.95
– Professional: $495

La version totalement gratuite est téléchargeable MAIS elle est extrêmement limitée puisqu’elle n’autorise qu’un seul lancement des tests, avec les réglages standards. Je pense que l’on devrait retrouver d’ici peu la version Basic (ou Advanced) en bundle avec certaines cartes graphiques…

Voici une petite compilation de liens pour vous aider à mieux exploiter 3DMark Vantage:

3DMark Vantage is the new industry standard PC gaming performance benchmark from Futuremark, newly designed for Windows Vista and DirectX10. It includes two new graphics tests, two new CPU tests, several new feature tests, and support for the latest hardware. 3DMark Vantage is based on a completely new rendering engine, developed specifically to take full advantage of DirectX10, the new graphics API from Microsoft.

This new benchmar is available in 4 versions:
– Trial: free
– Basic: $6.95
– Advanced: $19.95
– Professional: $495

The free version is downloadable BUT it’s very limited since only one launch is allowed with standard settings. I guess we should find soon the Basic version (or Advanced) as part of the bundle of some graphics cards…
