I run mainly 3d apps and have no need to run 12 threads when I only have 6 cores. If I wanted 12 cores I would have bought 2 proccessors each with 6 cores.
Article : On the 3D content creation part, CineBench 10 registered a neat boost of about 17% when HT is enabled. Overall, HT is good for numerous applications out there that are multi-threaded but we aren't seeing any benefits for the latest games out there now.
The only negative effects they posted were on games not rendering or other applications.
Other article: Contemporary video codecs in Core i7 platforms run remarkably fast. It is obviously due to Hyper-Threading technology that allows the CPU to process 8 threads at the same time.
Although Adobe Photoshop is not one of those applications that can load any number of processor cores (physical and virtual) equally efficiently, the advantage of Core i7 processors is beyond doubt here, too. We see the same thing in another graphics editor â€“ Paint.Net.
The third part, "Rendering" was the only expection:
We have no complaints about Core i7 performance during work in different 3D modeling applications. However, when we got to AutoCAD engineering suite, AMD Phenom II X4 955 suddenly outperformed all Intel solutions. Even the frequency increase didnâ€™t help Core i7 family to win the leadership in this test.
I'm no expert, but everything I've ever read or seen has shown the advantages of HTing in certain applications, especially rendering, editing, and 3D applications.
Looking for more input on this.
