Michael Moore Posted September 12, 2007 Share Posted September 12, 2007 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 Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted September 12, 2007 Share Posted September 12, 2007 Get the quad. Quote The Paint.NET Blog: https://blog.getpaint.net/ Donations are always appreciated! https://www.getpaint.net/donate.html Link to comment Share on other sites More sharing options...
Michael Moore Posted September 12, 2007 Author Share Posted September 12, 2007 Thanks Rick. I was thinking that even with the drop in speed that the 2X cores would be better, but that was just a WAG on my part. cheers, Michael Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted September 12, 2007 Share Posted September 12, 2007 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."

trippdoctor Posted September 13, 2007 Share Posted September 13, 2007 I would wait for AMD to come out with there new CPU I believe they are going to making up to a 8 core CPU. I know they have a quad on the market right now. Quote Trippdoctor | PDN Fanatics | Get Paint .NET Link to comment Share on other sites More sharing options...
Rick Brewster Posted September 13, 2007 Share Posted September 13, 2007 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.
