Imagine this base configuration: 1-cpu board with a 4-core processor, performance is 100%.
How different from that configuration performance-wise will be:
- 2-cpu board with 4-core processors
- 1-cpu board with 8-core processor
The total number of cores in both configs is 8 and that's twice as many as in the base config, so my guess is their performance is supposed to be 200% of base config, but then I'm not knowledgeable enough in this area to make a decent guess.
Price is not my concern in this question, I just want to know how the performance changes if the total cpu core number increase is done within and outside a single processor.
My personal interest lies in gaming and game development. I don't know about other games, but my own games I try to make multithreaded, so they could take advantage of all those cpu cores on my pc.
It's dependent upon what it is your going to be doing, for example if your compiling code you want to be worrying about threads not cores. Performance is relative to application. Provide more detail and you get a more precious answer. – 50-3 – 2013-09-11T09:03:43.687
