CPU optimization for PDN


Recommended Posts

Our benchmarks show very impressive scaling based on the number of cores in a system.

After working with PDN for the last couple of weeks I'm obviously going to have to replace my 5-6 year old 1.8M P4 system soon. :) At my price point I can consider either an Intel Core 2 Quad Q6600 2.4Ghz or a Core 2 Duo E6850 3.0Ghz.

I'm wondering how much difference I'd see between running PDN as the sole active application on the duo 3.0 vs the quad 2.4. I don't have the knowledge to judge if two cores at a 25% higher speed would be more productive for PDN than 4 cores at the slower speed.

Since I prefer to not change PCs more than every 5-6 years I'd like to optimize the spec as much as possible before getting a new one.

Thanks for the advice,

Michael

Yeah I've done a lot of work to make sure that, where appropriate or possible, Paint.NET is optimized for "N" threads instead of a static number like 2 or 4. Everything from the effect rendering harness, layer blending/composition, gradient tool, etc. ... it's all "N-threaded."

AMD only has a quad core server processor right now. The desktop chip won't be available until later this year, and an 8-core processor is a long ways away. (An 8-core system, aka workstation, comprised of two 4-core processors, is another story ... still very expensive.)

You really cannot go wrong with a Core 2 Quad at this point (Q6600, Q6700, QX6850). I personally have a QX6700.
