i aint sure bout this either, i just ordered an i7 from pc specialist only to change it to an i5 after i read this on the steinberg website.
For an overview on how Hyper-Threading actually works, please see this Wikipedia article (external link)
So how does Hyper-Threading affect the performance in our applications?
We have found that - depending on the system environment - having Hyper-Threading (HT) enabled can lead to performance issues and spikes in the VST performance meter. At very low latencies, even dropouts may occur.
If you are running a single Pentium 4 CPU system, enabling Hyper-Threading results in an increase of processing power.
If you are running a Xeon HT multi-processor system (not all Xeon models support HT) or a Pentium Extreme Edition dual-core system, you should disable HT in the BIOS.
The same applies to the new Intel i7 (“Nehalem”) processors that re-introduced Hyper-Threading. We are currently investigating using an Intel i7 with HT enabled in conjunction with our sequencers. As long as our tests are still ongoing, we recommend turning off Hyper-Threading if any performance issue appear. On PC you can still disable the HT in the BIOS.
so i quickly went online and changed my order to an i5 (messing in bios is over my head) only to then find a few threads that suggest steinberg are talking out their blow hole as most seem to get the benefits of H.T, i dont know enough about computers to take the chance so i’ve stuck with i5 but it would be nice to know the deciding factors in which make it work or not
overall this is good advice although sometimes not. my new pc was only gonna have 8gig ram but ended up with 16gig, totally overkill for my purposes but the difference in price was about £35, so why not, it only makes it more future proof, i just think its the same with i5 vs i7
