"A peculiar alliance has recently come into life. Forces from the extreme left, the extreme right, environmentalist groups, trade unions of developed countries and some self-appointed representatives of civil society, are gathering around a common endeavour: to save the people of developing countries from... development."
- Ernesto Zedillo, former President of Mexico

Well, it was an engineering sample. I got it from an old friend at AMD. I had to upgrade the BIOS when I got it too to be able to use it, but once that was done it has worked just fine. I've been tormenting it a bit with my code though.

icastano,
well, I have a GF 6600 in the box now until I get a replacement card. Unfortunately it can't drive my 30" screen at its native resolution, so I'm in a double-pixel mode and everything is very large. Buying Nvidia would be an option if they had a better price/performance or better feature set. Currently AMD wins both of those. It happens that Nvidia has the better feature set, but I rarely see Nvidia beating AMD at price/performance.

Isn't 1.2 years a short time for card.
I suppose you are using it on the limits :>
Or maybe it is overheating.Is it on standard cooling?

Time to buy an NVIDIA board? :P

GPUs get better performane only if the amount of data is large enought and it depents on whether you are using it on the gpu. Good to have a good sse implementation

It's quite easy to demonstrate improvement on a specific experiment, I'm looking forward for real use case test. Mat4 product and inverse are such great topics

nice gain!

I'd love to see a fleshed out article about this- perhaps adding a GPU implementation for comparison

Sorry, I guess the post was a bit unclear. I actually implemented all the SSE stuff in MSVC first. But I also wanted to make sure it works in Linux before I go to great lengths with this idea since I want to keep cross platform compatibility. I only needed a few minor changes to make it compile and run fine under GCC in Linux so it looks like I'll keep this code.

ah - scratch last comment. you never said you needed to install linux in order to experiment with intrinsics... I misread.
