AI Thread Summary
The AMD Radeon™ HD7970 Graphics card offers 970 GFlops of double precision performance, making it a strong choice for applications like OpenFOAM and OpenCL, as well as custom CFD/CE projects. However, the distinction between the HD line and the FirePro V8800 lies primarily in driver optimization. The HD7970 is designed with gaming in mind, featuring drivers optimized for DirectX, which can still handle CAD tasks but may not be as efficient for professional applications. In contrast, the FirePro series is specifically tailored for CAD and other processor-intensive tasks, generally providing better performance in these areas despite potentially lower specifications on paper. The choice between the two should consider the specific software requirements and the importance of driver optimization for the intended applications.

HD7970 vs FirePro V8800

Is there any reason why I should not go with the AMD Radeon™ HD7970 Graphics? I mean it's a popping 970GFlops DP, which I think satisfies my needs and then some.

I will be working with OpenFOAM or OpenCL, and my own variant of CFD/CE with my own pre and post processing meshing suite. I don't know much about the drivers, because it isn't something I'm all that interested in, and so I'm not clear on what changes are made between the professional and the desktop drivers that affect performance. I assume much of this has to do with vector/scalar manipulation and optimizing the usage of the accumulators/registers.

I want to do a lot of this sort of thing!

I guess what I'm saying is, are the drivers tailored to the application, or the specific softwares themselves? Is it that the driver is tailored to CFE/CAD/CAE, or is it that the driver is tailored to Solid Works, AutoCAD, CATIA and so on . . . .

The HD line of cards have drivers built that are optimized for directX, mostly for gaming. Its still able to handle the demand of say CAD.
The firepro on the other hand is designed specifically for CAD and other processor intensive tasks and will generally perform better than the HD line even though on paper they might not appear to be as good.
 

Thread 'Is AI hype?'

In my discussions elsewhere, I've noticed a lot of disagreement regarding AI. A question that comes up is, "Is AI hype?" Unfortunately, when this question is asked, the one asking, as far as I can tell, may mean one of three things which can lead to lots of confusion. I'll list them out now for clarity. 1. Can AI do everything a human can do and how close are we to that? 2. Are corporations and governments using the promise of AI to gain more power for themselves? 3. Are AI and transhumans...

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
