Something for Tim
I looked through tons of notebooks with A10 chips and integrated HD graphic, this should just work with the open driver (it is mostly 7660G)?
Then there are a lot of notebooks with an extra dedicated AMD Radeon HD 7970 to use AMD Radeon™ Dual Graphics (like SLI/Crossfire?). Would this be supported in the open driver or does it use Crossfire (and will probably never be supported*), which isn't supported if I check the matrix?
I understand HD 7xxx is radeonsi, does it work at all yet or are the missing features 'just' about performance?
* I used to have an HD 4770 crossfire setup in the past, when just the open driver came out and nothing happens since then with the open driver...
Thanks guys, I found some interesting benchmarks:
It looks the CPU related tests are faster with the binary driver, so it uses the GPU to support CPU related load which the open driver doesn't yet?
OK, Fedora 17 with Linux-3.5, x-server 1.12 and ati-driver 6.14...
Nope. The x264 etc differences are due to something else, perhaps the different kernel.so it uses the GPU to support CPU related load which the open driver doesn't yet?
There doesn't yet exist magic technology to run something built for a cpu on a gpu.
The Intel CPU is faster in all tests except the 'Flexible IO Tester', where it lacks behind the apu. Does that imply, the apu is more responsive under load? Like in this video (Llano chipset, not Trinity) Notebook Test: AMD Llano vs Intel Sandy Bridge
The Intel CPU Speed advantage is between 0% (FFmpeg) to 100% (x264).
$143.68 vs $570 (chip price only on amd.com the desktop version and intel.com the mobile version)
Graphic tests cannot be compared, though I am happy that my 6970m with open drivers can compete with the Catalyst driver on the integrated GPU (not mentioning OpenArena, but totally playable ). The dedicated AMD card would be working well in both laptops. The versions of the open radeon driver and x-server are too low to support the integrated GPU, this is why it says LLVMPipe.
See the decoder ring below the feature matrix.
