AMD Fusion with Phenom II and HD4890?

[quadomatic]

Does the AMD fusion utility provide any sizable performance increase for games on computers using AMD Phenom II cpus and HD4890s (or HD5770s?)?

Just curious since I now have an AMD quad core and am looking to get an HD5830

Doesn't seem like a huge boost in games but certainly won't hurt to run it and any boost is a good boost.

If I recall correctly, AMD said part of the benefit is in non-frame rate related areas as well... such as level loading times.

I haven't tried Fusion but did play with Overdrive, and it's like a poor man's lobs.. or Turbo Boost. As for Overdrive, it lets you assign processor affinity, multipliers per core, and vCore on-the-fly. Imagine NV's control panel and replace the AA, AF, etc. with those and you get the idea.



If you look closely you can see it has assigned 3 cores for GRID at +1 multipliers. Interestingly it lowers the unused core's multi by -3. You have to be careful with AMD's profiles because I saw it raising the multi by +2. If you've already overclocked your CPU to the limit, that will obviously cause trouble. And overall I felt it was not polished enough and didn't bother with it for long.

On the other hand, the ability to assign affinity can definitely come in handy. I suggest to ignore AMD's profiles and try creating custom rules and see how it works.
