Tech Things You Dont Know But Are Too Afraid To Ask.

[Snickerzz]

Well sometimes with strange things on google you dont get answers

 

Low is good it means less people had a broken part

or les people have bought the product :P 1 RMA since 2005! (only 1 product sold)

Hyper Threading is a way to create virtual cores. It is a bit tricky to explain, but I'll try to put it as easy as possible. Take for example an i5 quadcore and an i7 quadcore processor. Both are quadcores, but the i7 has Hyper Threading (HTT) which means it has 4 extra virtual cores. Of course those virtual cores are not real cores, but it is a way to make 1 core process two different threads at the same time by sharing the CPU parts which are idle because they are not used by thread 1 but can be used by thread 2. So basically the i7 is faster (most of the time) when processing a lot of data.

 

Here is the trouble I am having with HTT. You said "it makes 1 core two different threads at the same time". A virtual core is not as powerful as a physical core. This I know. So do you end up with one physical core and one virtual core or do you end up with two virtual cores (from 1 physical core)? I take it, it is the former. So with that, is the physical core less powerful now that you have to take some processing power and dedicate it towards the virtual core? So, is a single i5 core more powerful than an i7 core (2500k vs 2600k)? If you are not doing a lot of multi-threaded applications, would it be more beneficial to disable HTT?

 

Sorry if this is taking the thread off topic by focusing too much on one topic. PM if you feel it is.

Nah, its fine, i want people to get as much help as they need :D

No, a single i7 core will be just as powerfull as an i5 core (assumed they're the same cores on the same clock speeds). What you end up with is indeed one physical core and one virtual core /core. What HTT does is using the parts of the core that are not used by thread 1 for thread 2 which makes your core handle more threads/ certain amount of time compared to the i5 core. But in some cases HTT is the cause of reduced core performance compared to the performance of the i5 core for thread one. So you are right about disabling HTT when it isn't of much use to you. You'll end up with a modified i5 when you disable HTT because the i7 has more cache compared to the i5.

What does a Hyper Threading do?

 

Non HT CPU's have a single thread per core and HT CPU's have two threads per core, I think Intel demo'ed a chip with 4 threads per core a while ago

[Samdb]

The ones that flip out? 

 

They're there because I use them :P

Fair point :)

[joelthezombie15]

Fair point :)

I use them aswell.

[Samdb]

I use them aswell.

Well, I seem to be outnumbered.

[joelthezombie15]

Well, I seem to be outnumbered.

Yup. you are the weird one now.

The Doctor was massively outnumbered, look where he ended up :)

personally I am a shy people, I afraid to ask, talk, and say. But, I find out typing on forum is quite fun. Mabye you can locate my location but you dunno where and who am I.

What's with all these Intel sockets!!!!????

[rashdanml]

Why are there feet on the bottom of keyboards? I never seem to use them, is it just an ergonomic thing?

Variable height/angle for people who prefer it. It really helps to be as comfortable as possible while typing for extended periods.

I don't think there is really a "best" way to do it. I think its kinda like installing the mobo, some install the processor when the mobo is in the case and some don't, its really just preference, at least I'm pretty sure.

Thermal paste is actually not a preference, people just assume it is

but go ahead and spread it yourself, test it yourself and see what is best?

What do you mean? theres only like 3 in use right now. 1155 (Ivy and sandy) 1150(Haswell) 2011(sandy-E)

They seem to go through more than AMD though, esp. the last four years.  That's what I meant.  1366, 1156, 1155, 1150, 2011.

 

It confuses me somtimes. :(

Well only ones that are relevant are 1155, 1150, and 2011. the rest are old and arent used much anymore.

The fact that's three different sockets RIGHT NOW is what made me confused updating my system this year :P

[wtfxmitchell]

What does a Hyper Threading do?

it's just a virtual cpu core like this: your cpu has 4 cores but with hyper threading it still has 4 but acts like 8

i know it isn't precisly the same thing but it is in the same line

[Samdb]

Ya, with an annoying companion and poor story progression.

Touché

Well, on the red side there is AM3, AM3+, FM1, and FM2 that are still being used.

[joelthezombie15]

Okay here is another. What mouse sensors are good and what ones are bad?

[FireFox]

The different sockets aren't difficult to desypher, if there was more than 1,000 different sockets then fair enough lol

 

There are only three from Intel, 1150, 1155 and 2011 that are mainly used (disregarding older ones) and four from AMD, I don't see it as difficult or confusing :P
