Ok, after various issues (if your luck is as legendarily bad as mine, don't start building a computer on a friday the 13th) I now have my Bulldozer rig working in a way I'm fairly happy with.
For the time being, the graphics card is an HD4830 that I had lying around, till the HD7770 comes along (and my bank account is replenished). By extrapolating the results of Micheal benchmarks with fglrx I'd say it's equivalent to the HD6670 performance-wise.
Right now dual-booting Xubuntu 11.10 32 bit and openSUSE 12.1 64 bit.
Quick observations so far:
- Turbo Core isn't working properly in any of those distros, although I've enabled it in UEFI. Frequency never goes over the nominal 3.3GHz on any of the cores.
- Temperature monitoring is a bit all over the place (with 10-15C spikes when loading a program), though I believe that it's because idle temps are wrong. Even with standard cooler and all cores maxed, the highest I've seen is 50C though. Which I find quite decent.
- Quick Unigine tests show a noticeable difference in performance between 32 and 64 bit: 950 vs 1130 respectively in windowed mode with tesselation off. The lower 32 bit score is the same in both Xubuntu and openSUSE. GCC-32bit lacking optimizations?
Of course I'll run PTS as soon as I get the time, though I thought you guys might want something specific?
