Hex i7 is probably the most cost efficient for high performance, otherwise use multiple Xeons if you have money to burn.xavier wrote:[*] What make - i7, Xeon, AMD?
At 32 you start running into OS issues...[*] How many cores - is there a limit in what AfterShot Pro can utilize?
In contrast to the initial hyperthreading that Intel had ages ago, the current chips do have a useful hyperthreading that is usable for AS.[*] Hyperthreading - does anyone have some data on its usefulness in AfterShot Pro?
If you want OpenCL support, get a server grade card, not the consumer cards.[*] Anything else I forgot?
As has been written so that the slightly smaller caches of AMD work well. But, a 6 core i7 will still outperfom an 8 core AMD, due to the hyperthreading which results in a runtime behavior of 12 cores.theWiki wrote:I would also consider the newer 8 core AMD processors. If you have an app that can use all their cores (like Aftershot) they can perform VERY well for the money.
The problem is, as soon as price enters the question, one needs to look at specific chips, as price goes up exponentially at the top end...xavier wrote:That was just to know if it would be better to invest on graphic card or a CPU, at a given price tag.
I am just starting to look around, I shouldn't have referred to a specific processor...
?Oh definitely, but those are $500-1000 CPUs and you can get the AMD FX-8350 for $200. The Motherboards for the Intel hex cores are little more expensive, too.afx wrote:... a 6 core i7 will still outperfom an 8 core AMD, due to the hyperthreading which results in a runtime behavior of 12 cores.theWiki wrote:I would also consider the newer 8 core AMD processors.

Ok, thanks a lot for all this information already - I really appreciate.afx wrote:Unfortunately, I don't know of any benchmarks that will show where the cross over point between CPU and GPU performance is. I'd love to see that....

I actually do. Although I've never done it before, it looks like a lot of fun.Dutchmm wrote:Re-reading your original post, it seems to me you aren't likely to want to build your own system.
The other bad news is that they usually take a huge margin (may be country-dependent... I'd have to check now I moved). I could always build a cheaper machine than the Dell equivalent, and use the difference to get a more powerful one with fancy silent parts (case, fans) - but in the end it always ended up more noisy than a Dell for some reason.Dutchmm wrote:The good news is that the PC makers get their components for much less than theWiki and I can buy them, because they buy in bulk. The bad news is that you will have to compromise on the "best fit" of features that you want.
A Lian Li case with with proper silent fans is really silent. I don't even hear the GPU fan in my box.xavier wrote:I could always build a cheaper machine than the Dell equivalent, and use the difference to get a more powerful one with fancy silent parts (case, fans) - but in the end it always ended up more noisy than a Dell for some reason.
It is. And not at all difficult.xavier wrote: I actually do. Although I've never done it before, it looks like a lot of fun.
you might be a Flemish speaker . I can recommend a store, too - I used to buy my components from azerty.nl, (despite their name they do not speak French 
). The components always arrived well packed.
