yes. but what SSE3 perf is showing me.
is the only performance improvement gonna come from this. is in software coded for the new AVX SSE4 additions which finally made use of what was likely available in the processors already. either too hard to code for, with the lazy programmers.
making it appear like this generation is improving on die performance. while its really more optimizing the available then actual rawr performance gains from more compute units.

would these improvements shown , go beyond the software used, or be equal for improvements for all the alternatives.

cause if it only improves the performance with 1% of the software you use. but if you switched all your software, then you could get upto 10%?

That's an ugly abuse of math, AVX code is up to 100% faster than SSE3 so if you switch you get that boost +10%. And in some cases a simple recompile will get you a significant chunk of that gain. As for lazy coders, optimizations can lead to incorrect output, computers do these equations by brute force, optimized code tends to work by simplifying what you can get away with. But sometimes when your code is solid you have to draw a circle and treat it like a square to speed things up (note exaggeration). Not every good optimization can be figured out in time to ship a product.

To be honest I think you can't get more SSE3 out of the Intel architecture, every sse port works crazy fast now, Intel and AMD may only have core width left to them as a tool to improve performance in that area.
