Updated OpenCL list? Getting new hardware...

Hi there,
I'm getting some new hardware. A few of the options involve Intel's 4400HD chipset which has OpenCL support. Some have dedicated RAM, some have Shared RAM.

The list on this page is a bit out of date:


Just wondering if OpenCL will help me or not (because I have the choice between a Core i5 and i7 and the configuration changes just to get that are fairly ridiculous in price vs. probable performance).

Thanks!

  I'd like to see an updated list as well. I have an R9 280x and I see 0% GPU utilization with CO 7.2.1 on Windows 7 x64, with OpenCL set to 'Auto' (and the latest non-beta Catalyst Suite).
  
  I am not sure if the list is outdated, or if they in fact have not yet started supporting newer cards.

  Hi
  
  I would opt for a i7 and a SSD that's large enough to hold the files you want to cull.
  In a desktop it's easy to add a GPU afterwards, but I would look out for a mainboard with PCIe 3.0, this doubles the IO speeds to the GPU versus the older PCIe 2.0.
  
  
  openCL is not used for some things, like local adjustments etc. More cores (real or HT ones) are used by c1. A similar i7 would add 50% speed to a i5.
  
  I'f also read that for AMD boards the openCL has to be recompiled with every start from C1 and takes a few minutes...

  I agree with Alain.
  
  Right now a decent, recent i7 chip offers plenty of processing potential for those situation where OpenCL is not available. Or not much help due to the relatively immature development cycle so far.
  
  Moreover, so far as I can tell, the underlying architecture for i7 based systems seems to offer more than you can be sure to find in an i5 based system.
  
  Bear in mind that in a year or two these comments may well be entirely out of date and meaningless - but some other comparative reference will have come along to take their place.
  
  HTH.
