About gflops plz see http://www.xtremesystems.org/forums/...d.php?t=256633

Afaik HT lowers per core performace but 'raises' the core count. Meaning a i7 with HT off will have performace rating of 100 on 1 core meaning 400 on four and with HT on Per Core PFRating drops to 75 but core count jups to 8. Meaning Anything that uses up to 4 Cores will be faster on a non HT's i7 but anything that uses more than 4 cores will benefit from it.
Bold explanation.

An 4 Core Usage aplication =

4 Non HT'd cores 400
4 HT'd Cores 300

An 6 Core Usage aplication =

4 Non HT'd Cores 400
6 HT'd cores 450

An 8 Core Usage Aplication =

4 Non HT'd Cores 400
8 HT'd cores 600

This is of course only in case the Aplication Code is superb and it really uses the cores.

Simply taken. Video Compression, WCG , Rendering ... HT will profit
Anything Else, HT will drop performace.

That's why we see a Gflops Drop in Linx with HT on.

I observed 4 GHz i7 930 with HT on gives me about 51 ~ 52 GFLOPS , HT off gives me around 58 ~ 60

I talk too much
