my friend bought a dell labtop, and it has Hyperthreading technology....hes asking me wtf that is..i said i'll find out by 2mor...

any idea's?
thanks

i was gonna post what rudebwoi posted as well. fishing for answers on DS to these kind of generic questions that can easily be answered by typing a simple query in google really is a bit annoying.

anyway, here's a short quote from an article

"hyper-threading (otherwise known as simultaneous multithreading technology or SMT) is the ability of one physical processor to execute two threads concurrently"

from http://www.2cpu.com/articles/42_1.html

Wow, soo fast!!!
5 mins...nicee.

thanks alot guys,

WHEEE
i have a p4 2.4 with HT and it OWNS

except when it comes to my tv card...when u try to watch tv with a HT enabled computer, it will crash invariably....


in sp2 there will be a fix for this from MICROSOFT
wheeee

i use sisoft sandra to benchmark with and without HT and the benchmarks speak for themselves...its good shit..mmm...HT....


the moral of this story is that HT owns...

HT is just Intels excuse for not getting a true home consumer aimed 64bit comp out in time to compete with AMD
Oh, and I never knew threads were circular, always thought they were sqaurish:P

DuperMan

...no it isn't! :P

:) Have a good day :P

IT IS IT IS IT IS!! *stamps feet*

Go suck down a coke, omo. :P Pepsi (wait, no make that River cola, heh)! Because I drank all the Coca Cola.

I love the HT ... In short it allows you to do whatever u want while ur doing things on your pc (which normally had to run alone)
I have a 3ghz 800fsb HT and its the most pc I have ever been truly happy with.

HT is just Intels excuse for not getting a true home consumer aimed 64bit comp out in time to compete with AMD
yeah right :)

Just as an example : there is no Amd, 64 bit or any bit processer that can rip a DVD and allow you to play a 3D memory hungry game without lagging (ex UT2004)
HT simply does :D

Had em Both A64 and P4 3ghz and the A64 Killed this piece of sh*t P4--
With the A64 with XP home i unpacked 4.3gb in 4 mins using WinRar the P4 is lucky to do it with a fresh install of XP pro in 15mins.
The A64 (though benchmarked lower on every site I read ) Ripped using DVD Shrink in about 1/2 the time of this P4(also the same DVDRW drive)
The Bench's usually only show you what you can do with the best hardware there is imaginable.
Both of mine --A64 was from Compaq -- P4 form Sony-- have the same shite hardware configurations on a lower scale though from those you read about.
Also this P4 runs so damn hot i am waiting for fire to come shooting out the sides of my case.
This P4 3.0ghz 800mhz fsb with 512mb DDR is only slightly faster than my Athlon T-Bird 1.0 Ghz @ 1.4Ghz with 1gb SDRAM -- but with winrar the T-Bird still kills the P4 in a side by side race --T-Bird 8 mins 28 seconds -- P4 15 mins 12 seconds both unpacking the same exact file with the same processes running.

hehehe

well first i thought ur reply was funny, because u seem to have a lot of anomosity towards p4 , maybe u felt cheated with the 64bit  ?  \o/
which is newer technology trying to prove itself with the old one..
real comparing should start when Intel release the 64 bit :-)
The way I see it , amds newest is still struggling with Intels old cpus !

anyway I have no idea what u were testing, but its surely not running with HT enabled,(I will assume that u know that dual channel memory has to be in place for HT to work)

ANYWAY
I am downloading and uploading at the moment, I am running a few other thinfgs i don't wish to share with everyone here.. and I decided to extract a 4,6 dvdr movie just to show u :)
eventhough its not even close to the times i normally get, if my pc was totally idle which never happens !!!

MY HT is enabled with Dual Channel (didn't really mean much bout HT technology here just the P4)---but---- My A64 COMPAQ still whooped that time you got with HT enabled --- also my 1GHZ T-Bird does only slightly slower than your P4 .
The reason i got rid of the A64 was the HDD burnt on me twice and Circuit City had no other A64 than the Compaq that i had already killed 2X. If they wouldn't have adopted a 15% restocking fee this P4 VAIO woulda been back the next day for an Athlon in a minute .
This is my 1st and last Pentium for sure:)


EDiT :
Also how can you say still struggling with old CPU's when both are new technology ?
And The EE seems to be a real waste of money (but than again Benchs done with unreal hardware configs)
And the new Dual Core Opteron will definately be something to compete with :)

You don't seem to trust the benchs done on the net.. so i wontt go there..
since i am always skeptic myself..
But generally speaking , nearly all say that the P4 is superior when it comes to applications, and the 64bit is better for gaming..
which in this case (extracting) it would mean that P4 should be faster.. but ur saying that u got better times (4.3gb in 4 mins ).. which would mean a 4.6 would take u 4½ min ..
while i did it in "6:40 something".. BUT i have my computer on near full load with lots of other things.. and this file was 300mb bigger anyway I don't think that i can do it in 4½ min anyway.
I never remember it being that fast with or without load !!

But u also said that when u tested it , it took 15 min for the p4 and only 4 for the 64bit to extract a file so i will assume that u exagerated on both ;)

But all this talk is besides the point.. because HT still beats the AMD 64bit in performance ...and thats what all the benchmarking is all about...
HT can do 2 tasks at the same speed it would take to do one..

so lets say ur extracting a rar, and the 64bit can do it in "4min" while intels takes "7min"..
but while extracting ! The HT allows u to run games smoothly, rip movies whatever without u noticing that there are 2 parallel jobs at the same time...

my neighbor bought the amd 64bit, and when he asked me what i thought before... i said get it if u want to play games..  and i was right ! Its great and fast for gaming.. but try to extract or rip a movie (minimise it ) and start the game again ..then weep But u get to see every frame in the game nicely :)
and that was "Call of Duty" not some ram hungry game !!!!

needless to say with HT its not only possible, but works perfectly

My P4 weeps at anything i do in HT --- I cannot print a cover and burn DVDR with any kind of decent speed --- one prob I know this thing has ATM is 512 of pc2700 -- gonna get 1 gig of 3500 for this damn thing -- also the OEM sony board kinda sux but hey when they give no interest it saves me $$$$ when buying a new PC :)
But they were no Exaggerations on the time with WinRar.Just redid it with a 4.68 gb with no extra processes running --- 13mins 41 seconds.So a little better than previously but not much .IMO this thing ought to do a ton more than the A64 especially in the price difference.

Did you try extracting the movie on a disk other then your OS?
I have 2 disks, same speed and all that. On one without the OS running it takes me 1:15 min for 700 mb, on the other one with the OS on it running it takes met 4:30 min

@ScHiZo the difference in times u have is very big.. try moving the pagefile from the main OS holding disk.. maybe thats ur issue

@sn8khd28 "IMO this thing ought to do a ton more than the A64 especially in the price difference.
Ok first point we agree on tonight :) I also think that for the money differnce P4 should be a clear winner , but it obviously isn't.
13mins 41 seconds is like double the time and more than what it takes me..
now the memory I have maybe is the difference !!!
2x512= 1gb 3200 (400mhz) CL3 ,It was 512 before but i upgraded and thats when the HT started working and it did make a difference !
I think ur slower speeds are due to hardware issues ,like memory,hardisk,cooling etc... for ex my mobo is also an Intel... D865PERL (nothing special though)..
The 512 u have ,is it one memory stick ? If so .. then ur not running HT.

Like i said before, this is the first machine i have had, that i was really satisfied with, it boots very fast.. programs like photoshop start fast.. to log out and logon from one user to another takes a couple of seconds...more like the screen blinking.. u get the picture !
First i would strongly advise you to increase the ram ... and then test again

Ahhh now maybe you will see my point --2 sticks X 256 PC2700
BUUUUUT this is the exact same ram i had in the A64 (Maybe a different brand but otherwise the same)
So the true benchs IMO are on Lower configured PC's not the GoD ALMiGHTY's built by some to run a bench on .
Because MOST users I think are gonna buy off the shelf technology from Dell-Compaq-Sony...etc for around $1000.
I do wish i woulda just waited til i had cash and built another PC ( WHich is what my T-Bird is and is almost as fast as both the A64 and the P4 in comparison price and clock it actually kills em both lol)

Damn i'm stupid...
sorry, gonna wait 'till Intel releases a 64bit HT processor before i pass halfwitted eager fanboy judgement:)

DuperMan

I would pick a p4 over a amd 64 too, but for a very different reason.
For 2 clients I recently installed 30 amd's, and 22 p4-prescotts

amd= amd64bit 3000+ on asus k8v-deluxe with ati 9200
p4= p4 2.8E prescott on asus p4p800-vm (cheapo with onboard vga)
both with corsair ddr400 memory, and wd harddisks

all installed with windows XP home edition.
We always check the logfiles after installation of windows and drivers. About half of the amd's had some unexplainable errors in the logfiles, on 2 of them the installation failed, and we had to reformat the harddisk.... The other half worked fine.

The p4 all completed the installation without a single error.

I am not saying the cpu is to blaim, it probably isn't, but as long as there is no real good motherboard(meaning with not too many bugs)
I will stick to the athlon xp and p4

this is an awesome thread.  i really enjoyed reading it.  thanks a bunch for your opnions candyman & sn8k

oh and i agree with duperman :-P

since i still have a few yrs old pc, i'm well behind hardware developments :-)

i love pentium and dont think would ever consider amd, but that's me.

when the 64-bit processor development race took off, i distinctly remember that intel and amd took different approaches to it.  amd was developing the 64-bit from the 32-bit core (or whatever it might be called) which meant the ability to deliver faster to the market and make it very compatible with current 32-bit applications.  intel took the risk of actually doin' a "true" 64-bit processor, ie takin' longer to bring to market and not optimised for 32-bit, but kill amd in head to head benchmarkin' with 64-bit applications.

needless to say, i lost track of all that sometime ago :-)

@Candyman just moved the pagefile, but no speedchange at all :( I do know that if I put win2003AS on it that the rars extract at high speed, always less then a minute, any ideas?
