Go up one level in this thread
A program can't be Hyper-threading enabled, a CPU can be. I would say a program is Multithreaded or SMP-enabled, or something along those lines. But that's just semantics, not really important :) I took his question to mean 'Will I see a boost in performance with HT on on a single proc.' There are a few apps that do slow down from what I've seen on the various pages, but like Ace's says, a vast majority show improvements, even with one CPU and single threaded apps. Anyways, the benches I've seen (see the bottom half of the Anandtech page I linked) provide evidence that this is the case, I haven't seen much to say that it isn't true. You could very well be right. And my curiosity is getting the better of me :) After I'm done having various engines check out the position at the root of this thread, I'll run some benches with some single-threaded apps. >Even if this were true with a chess engine (which I will require evidence to >believe) the answer to the topic "Is Fritz, shredder, or Junior hyper-threading >enabled?" is only "Yes" for SMP versions of those engines.
