[:-?] Hyperthreading... hmmm

[BigWill]

I got my K series around about a year ago. I got one with a P4 so i wouldnt have to replace it for a while, - and to show off to my friends stuck with their x86 systems :smileygrin: .
Anyways, i ran some benchmarking software today, and according to the software and as a complete surprise to me, my system supports hyperthreading but its disabled .
So, my question is.. can i enable HT, is it safe, or am i trying to do something impossible.

They have locked out all the good stuff in BIOS 😞 . All i wanna so is enable hyperthreading to try it out , damn sony the mean buggers!... Nice laptops thou lol

I have a desktop with HT and you don't really notice the difference - some benchmarks may show it up but it's nothing special IMHO - better to get more GHz or more cache.

Also, HT makes the CPU work harder --> generate more heat. Not what you need in a laptop environment.

The thing is, its work only when the Software support it.

I have HT in my Desktop, it doesnt really make any difference, if you look on the pic I posted both sides of the processor went bonkers when I opened all the tabs in FF at once, just pretend the option is not there!!

You're right DT, more heat is just what you DON'T need

Hmmm, whether Intel will be able in future, to develop a great CPU like the Pentium3S was it? If you compare the power of all 3GHz Pentium 4 models, then you wouldn't notice any big different.

The good old Northwood with 3.06GHz beats them all. Like I said. They need 2MB level 2 Cache in order to compensate calculation faults. And the size of the Level 2 Cache is one reason, why they need so much energy.

True

It canbe in some circumstances, but in others it makes matters worse.

I guess Sony are being conservative with HT, I haven't seen many models that feature it, and in some that do, HT is disabled by default.

Unfortunately, what you soon become to realise is that Sony lock-down the system BIOS and disable many features such as RAM timings, SMART message announcements, PIO/UDMA modes etc...

I guess it's good for video editing
as one CPU handles video
while the other processes the audio
