This wasn't as easy to find out as I first thought, however I think you can. It has the AMD Radeon HD 6550D which apparently has 400 stream processors. So I am guessing it will, but you should make better checks before you buy it. If your computer you have now has a PCIe 2 slot you might want to think about buying a separate card if your interests are solely on cracking.

yes the docs say it is supported by opencl. so in theory, it should work. however, no one ever tested it

If someone test AMD Llano with oclhashcat, post result here.
I modified the oclExample.sh script to take arguments passed on the command line. Here is the performance with -n 800
chort@hydra:~/code/oclHashcat-lite-0.06$ ./oclExample.sh -n 800 -d 1 oclHashcat-lite v0.6 by atom starting...

Unfortunately, the APU paired with a 5870 (Cypress) decreases the h/s. I'm eagerly anticipating the next release of oclHashcat-lite that will allow running on mis-matched GPUs.

Do you try with oclHashcat-plus and wpa-wpa2 ?
But AMD Llano only allow CrossFire with HD 6450, 6570 or 6670

I've used it with -plus, not with WPA because I don't have any .PCAPs to use.
It doesn't need to be crossfired to work, just go into the BIOS settings and force the APU to be "always on." Then (on Linux at least) put a dummy plug in any card that you don't have hooked up to a monitor (on mine the APU is connected to monitor). Normally the BIOS will disable the APU if you have another graphics card installed and a monitor connected to the expansion card.

Yes I've tried with both GPUs currently (the default), but it slows down the 5870 too much. The 6550D runs full speed the entire time, but the 5870 stalls, goes to full speed, stalls, over and over. The overall speed is about 4/5 the speed of the 5870 by itself. I just tried on oclHashcat-lite-0.08 and the same is true
 It can still be helpful if you split a hash file into 1/6th and give 1/6 to the 6550D and 5/6 to the other GPU (or with -lite, do 5/6 of the brute-force space on one GPU, 1/6 on the on-die GPU, etc). |
