I will use this list as reference: https://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units I assume that all GPUs with codename of either Oland, Cape Verde, Pitcairn or Tahiti should comply to GCN 1.0 spec, unless the microarchitecture has bee explicitly specified. Browsing eBay right now and it seems like there aren't (m)any cheap laptops with GCN 1.0 GPU on board. I found two candidates, but they are both kinda expensive: - http://www.ebay.com/itm/Dell-Inspiron-15R-7520SE-i7-quad-core-8GB-RAM-15-= 6-Full-HD-Radeon-7730M-2GB-/182134028932?hash=3Ditem2a6808ba84:g:7tcAAOSw= xehXOegi - http://www.ebay.com/itm/Asus-N56DP-DH11-AMD-A10-4600M-2-3GHz-8GB-1TB-AMD-= Radeon-HD-7730M-15-6-Win-8-/252203481042?hash=3Ditem3ab87fb7d2:g:qUsAAOSw= 7FRWZeTe At this point it might be fastest (and easiest?) to just get the cheapest possible motherboard with PCI-E, cheap CPU, add some RAM and then buy a separate GPU card. Getting a separate GPU PCI-E card is easy because they always sell them with the marketing name, and then you can be 100% sure what you are getting. With laptops the sellers rarely specify the exact GPU model in a way that it would be searchable. But I will keep looking for a laptop, if I find a laptop with GCN 1.0 GPU I'll post a reply in this list.

I have amdgpu loa= ding (and when I start dogfooding that will be the driver that gets all t= he use), but debugging it is taking a backseat to fixing support gaps in = i915. A GCN1 system would actually be ideal as that's something that will= only be supported by radeon - at least until the end of the year. >=20 > Thanks. >=20 > -M --x26SaubFbRLVgFpbVlgdcbbPoS4dXQPT4-- --LqRr2iviHtx2eKA18i5OwwjE0ddJ0vfdL Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iF4EAREIAAYFAldUeBwACgkQTBivhqtJa25WkgEApeJm8sDCIspNliHZOG5tBvDY smj6WBetdbkCrLNvJpMBAKiNnMOMFFk0d5zgCf13Z8LNxFgPoH+G465eqp7cyRrt =zkbY -----END PGP SIGNATURE----- --LqRr2iviHtx2eKA18i5OwwjE0ddJ0vfdL--
