My vote is for How much speedup does a hyper thread give? (in theory).

I have always been interested in how much preformance hyper threading actually gives. In fact I often turn off hyper threading since increases the cache that is available for single threaded applications. It seems like Konrad has done alot of testing with hyper-threading and is very knowledgeable on the subject. Possibly we can talk to him about elaborating further on the subject or at the very least do some tests to see how hyper threading affects things your average user does (Photoshop, games etc..). Either way in it's current state the information within the answers is excellent.

  • Would you like to blog about it yourself or should we ask Konrad?

  • I would @ivo however I would not consider myself and expert on hyper-threading, Konrad may have alot more to offer here. I only started using Intel processors in my personal builds (actually my I5 2500k isn't even hyper threading) within the last 2 years. The only test PC I could use for this would be my Alienware with the I7 ULV and I don't think that processor would do it justice. Commented May 12, 2011 at 13:57
  • that's what's so great about blogging. You learn along the way :P Commented May 12, 2011 at 18:25
  • Unfortunately I don’t see a good way of testing in isolation the effect of hyperthreading on common applications. As far as I know this would require a pretty elaborate setup. Importantly, most programs don’t let you control whether multiple threads are used, and disabling hyperthreading needs to be done in the BIOS, which I don’t have access to on the machines that I could test on.

Restoring performance and estimating life of a used SSD drive?

How does a hard drive compare to Flash memory working as a hard drive in terms of speed?

I think it is an interesting topic considering the fact that many computers now ship with Flash Memory, like the MacBook Air. But will it be the thing that kills the hard drive?
