Aynu nidhaahno waxaad eegaysaa inaad soo iibsanayso Processor cusub oo aad si lama filaan ah u go'aansatid laba badeecadood oo labaduba isku mid ah oo warqad ku qoran, laakiin mid ka mid ah wuxuu leeyahay sifo loo yaqaan ' hyperthreading ' kan kalena ma laha.

Sida cad hyperthreading waa shay wanaagsan sababtoo ah waa inaad lacag dheeraad ah ku bixisaa, laakiin maxay qabtaa? Tan ugu muhiimsan, ma tahay wax ay tahay inaad^(you) daryeesho? Si aan uga jawaabno su'aalahan gubanaya, waa inaan u leexanno gaaban sida CPU-yada^(CPUs) ay wax u qabtaan.

Awood aan xadidnayn!

Xitaa haddii aanad dhammaan xiisaynaynin tafaasiisha farsamo ee wanaagsan ee tignoolajiyada kombiyuutarka, waxa laga yaabaa inaad hore u maqashay Sharciga Moore^{(Moore’s Law)} . Runtii maaha sharci dabiici ah, laakiin indho-indhayn ah in qaybaha aasaasiga ah ee wareegyada isku dhafan ay labanlaabmeen cufnaanta labadii sanaba mar ama wax ka badan.

Dhab ahaantii tani waxay ka dhigan tahay in waxqabadka CPU uu labanlaabmi doono labadii sanaba mar, taas oo ah heerka jibbaarada ee horumarinta. Haddii baabuurka adduunka ugu dheereeya uu labanlaab ka dheereeyo kii soo baxay laba sano ka hor oo isbeddelkaas uu sii socday muddo tobanaan sano ah, waxaan lahaan lahayn gawaari leh xawliga xiddigaha cilmiga sayniska. Markaa tani dhab ahaantii waa mid ka mid ah waxyaabaha ugu kacaanka badan ee ku saabsan tignoolajiyada kombiyuutarka.

Dhibaatadu waxay tahay in waxqabadka CPU aan lagu go'aamin cufnaanta qaybihiisa. Xawaaraha saacada, oo ah inta wareegyada xisaabinta buuxda ee ay ku samayn karto ilbidhiqsi, sida cad waa muhiim. Haddii aad qaadato CPU oo aad labanlaabto xawaarihiisa saacada, waxa uu samayn doonaa laba jeer sidoo kale. Ugu yaraan aragti ahaan.

Dhibaatadu waxay tahay, si kasta oo uu Processor-kaas u degdegayo, waxa uu markiiba samayn karaa hal shay. Waxa aan u aragno "multitasking" dhab ahaantii processor-ku wuxuu si degdeg ah ugu boodaa kumanaan shaqo oo kala duwan. Dhawr sano ka hor, waxaan bilownay inaan garaacno dhowr gidaar oo leben ah markii ay timaaddo samaynta hal processor si dhakhso ah oo dhaqso leh.

Haddaba, mid ka mid ah xalalka waxaa ka mid ahaa in Processor-kasta lagu dhejiyo wax ka badan hal CPU , si shaqooyinka kala duwan loo qaybsado. Maanta, CPU-yada^(CPUs) quad-core ayaa aad ugu badan qaabeynta guud.

Hyperthreading (HT) waa magaca Intel ee isla mar ahaantaana isku mar^{(simultaneous multithreading)} . Asal ahaan waxay ka dhigan tahay in hal xudunta CPU uu ka shaqeyn karo laba dhibaato isku mar. Macnuhu maaha in CPU -gu labanlaab ka shaqayn karo. Kaliya taasi waxay xaqiijin kartaa in dhammaan awoodeeda loo isticmaalo iyada oo la tacaaleysa dhibaatooyin badan oo fudud hal mar.

Nidaamkaaga qalliinka, mid kasta oo silikoon dhabta ah ee CPU udubdhexaadka ah wuxuu u eg yahay laba, markaa waxay ku quudisaa mid kastaa inuu shaqeeyo sidii iyagoo kala duwan. Sababtoo ah wax badan oo ka mid ah waxa CPU uu sameeyo kuma filna inay ka shaqeeyaan ilaa ugu badnaan, HT waxay hubisaa inaad lacagtaada ka helayso jajabkaas.

Yay tahay inuu danaynayo hyperthreading^{(Hyperthreading)} ?

Tani waa su'aal kale oo noqon karta wax yar oo dhib badan laakiin dhab ahaantii waa mid fudud markaad jebiso. Marka hore^(First) , aan soo saarno hal shay oo ku saabsan hyperthreading oo had iyo jeer run ah. Haddii ay tahay inaad kala doorato laba processor oo xamili kara tiro isku mid ah oo xadhig ah, laakiin aan lahayn tiro isku mid ah oo koofiyado ah, raac CPU -ga leh koodhadhyo badan oo muuqaal ah.

Tusaale ahaan, haddii aad leedahay laba-core, hyper-threaded CPU iyo non-HT quad-core CPU , xulashada quad-core waa doorashada ugu fiican. Marka la eego in ay isku dhow yihiin midba midka kale ee hal-thread, waxqabadka asaasiga ah. Waa maxay sababtu? Sababtoo ah Quad-core CPU waxay leedahay qalab farsamayneed oo badan.

Khudaarta dhabta ah waxay timaadaa markaad haysato laba CPUs oo leh tilmaamo jireed oo isku mid ah, laakiin mid wuxuu leeyahay HT kan kalena ma jiro. Hadda su'aashayadu waxay la xiriirtaa software-ka aad rabto inaad ku shaqeyso. Haddii aad haysatid softiweer ka soo saari kara dunta ku filan si aad u isticmaasho xargaha HT sidoo kale, waxaad arki doontaa kor u kac weyn oo ku saabsan doorashada CPU ee leh hyperthreading. Si fudud^(Simply) sababtoo ah midna awoodda farsamaynta lama lumin oo qaybtu waxay u shaqaynaysaa meel u dhow awooddeeda buuxda inta ugu badan ee suurtogalka ah.

Haddii software-ka aad rabto inaad ku shaqeyso uusan dhalin dun ku filan si aad sidoo kale u isticmaasho qalabka farsamada ee HT, waxaad arki doontaa wax farqi ah oo ku saabsan waxqabadka.

Dhaqan ahaan hawlgallada sida samaynta CPU 3D , codaynta fiidiyooga, iyo wax-ka-beddelka sawirku waxay abuuri doonaan xadhig badan inta CPU -gaaga liita qaadan karo. Si kale haddii loo dhigo, codsiyo xirfadeed oo badan oo casri ah ayaa dun-gaajaysan. Tani waa sababta Hyperthreading lagu xaddiday CPU-yada^(CPUs) xirfadleyda ah sida i7 iyo wixii ka sareeya^{(i7 and up)} .

Codsiyada caadiga^(Mainstream) ah sida ereyada ereyada iyo daalacashada shabakadu ma samayn doonaan wax ka fiican oo ku saabsan hyperthreading, xitaa haddii ay dhalin karaan dun badan. Si fudud^(Simply) sababtoo ah baahiyaha codsiyadaas sida ay dadka badankiisu isticmaalaan xitaa ma siiyaan CPU-yada^(CPUs) heerka gelitaanka waqti adag.

Su'aasha Ciyaarta Weyn

Ciyaaraha fiidyowgu^(Video) waa codsi kale oo caadi ah kaas oo si cadaalad ah u necbayn Hyperthreading^{(Hyperthreading)} . Waqtiga qorista, sanadka 2019, matoorada ciyaarta fiidyaha ee ugu dambeeyay waxay bilaabayaan inay noqdaan dun culus. Taas oo la micno ah in CPU-yada^(CPUs) karti u leh HT ay si fiican uga shaqeyn doonaan iyaga. Magacyada hore ma arki doonaan wax faa'iido ah haba yaraatee, marka laga reebo dhowr ciyaarood oo nooca jilidda ah oo si culus u isticmaala AI ama hababka kale ee CPU-centric.

Taas miyay la macno tahay in kombayutarkaga soo socda ee ciyaaraha uu leeyahay Hyperthreading ? Shaydu waxay tahay, waxaan hadda u dhaqaaqeynaa suuqa guud ee CPU halkaasoo lix-, sideed- iyo laba iyo toban-core CPUs ay yihiin kuwa caadiga ah. Markaa, way aad u fiican tahay in la helo xudunta jireed oo badan halka ay suurtagal tahay.

Jawaabta Fudud

Waxaan rajeyneynaa in sharraxaadda sare ay si ku filan u caddaatay, laakiin aan u kala qaadno gunta hoose:

• Haddii aad qabato shaqo xirfad leh, dun-culus, arrimaha Hyperthreading
• Haddii aad tahay isticmaale guud, ha ka welwelin!
• Haddii aad tahay ciyaar-yahan, mudnaanta sii in aad yeelato koorasyo ​​badan dhismahaaga soo socda ee HT, laakiin hel HT marka lagu daro haddii qiimuhu sax yahay.

Hyperthreading waa tignoolajiyada weyn, laakiin maaha mid u qalma qiimaha qof walba. Hadda waa inaad ogaataa in "qof" uu adiga yahay iyo in kale!

What is Hyperthreading and Why Should You Care?

Let’s say you’re looking at buying a new processor and suddenly you have to decide between twо products that are both just about the same on paper, but one of them has a feаture called hyperthreading and the other doesn’t.

Clearly hyperthreading is a good thing because you have to pay extra for it, but what does it do? Most importantly, is it something that you should care about? To answer these burning questions, we have to take a short detour into how CPUs do their thing.

Unlimited Power!

Even if you aren’t all that interested in the fine technical details of computer technology, you’ve probably heard of Moore’s Law before. It’s not really a natural law, but an observation that the basic components of integrated circuits were doubling in density every two years or so.

In effect this meant that the performance of a CPU would double every two years, which is an exponential rate of improvement. If the fastest car in the world was twice as fast as the one that came out two years ago and that trend continued for decades, we would have vehicles with the speeds of science fiction starships. So this is actually one of the most revolutionary things about computer technology.

The problem is that the performance of a CPU isn’t just determined by the density of its components. It’s clock speed, which is how many full calculation cycles it can perform in a second, is obviously important. If you take a CPU and you double its clock speed, it will perform twice as well. At least in theory.

The problem is that, no matter how fast that processor works, it can only do one thing at a time. What we perceive as “multitasking” is actually the processor rapidly jumping between thousands of different jobs. A few years ago, we started hitting a few brick walls when it came to making a single processor faster and faster.

So, one of the solutions was to put more than one CPU in every processor, so that the various jobs could be divided between them. Today, quad-core CPUs are pretty much the mainstream configuration.

Hyperthreading (HT)is Intel’s name for simultaneous multithreading. It basically means that one CPU core can work on two problems at the same time. It doesn’t mean that the CPU can do twice as much work. Just that it can ensure all its capacity is used by dealing with multiple simpler problems at once.

To your operating system, each real silicon CPU core looks like two, so it feeds each one work as if they were separate. Because so much of what a CPU does is not enough to work it to the maximum, HT makes sure you’re getting your money’s worth from that chip.

Who Should Care About Hyperthreading?

This is another question that can be a little complicated but is actually pretty simple when you break it down. First, let’s put out the one thing about hyperthreading that’s almost always true. If you must choose between two processors that can handle the same number of threads, but don’t have the same number of cores, go with the CPU that has more physical cores.

For example, if you have a dual-core, hyper-threaded CPU and a non-HT quad-core CPU, the quad core option is the better choice. Given that they are close to each other in single-thread, single core performance. Why? Because the quad-core CPU has more physical processing hardware.

The real pickle comes when you have two CPUs with the same physical specifications, but one has HT and the other doesn’t. Now our question really has to do with the software that you want to run. If you have software that can spawn enough threads to use the HT threads as well, you’ll see a significant boost from opting for the CPU with hyperthreading. Simply because none of the processing capacity is being wasted and the component is working near its full potential as much of the time as possible.

If the software you want to run doesn’t spawn enough threads to also use the HT virtual cores, you’ll see literally no difference in performance.

Traditionally operations such as CPU 3D rendering, video encoding, and photo manipulation will create as many threads as your poor CPU can take. In other words, many modern professional applications are thread-hungry. This is why Hyperthreading has been restricted to professional-tier CPUs such as the i7 and up.

Mainstream applications such as word processors and web browsers aren’t going to perform any better with hyperthreading, even if they can spawn more threads. Simply because the needs of those applications as used by most people doesn’t even give entry-level CPUs a hard time.

The Big Gaming Question

Video games are another mainstream application that’s been fairly apathetic to Hyperthreading. At the time of writing, in 2019, the latest video game engines are starting to become more thread heavy. Which means HT-enabled CPUs will perform better in them. Older titles won’t see any advantage at all, with the exception of a few simulation-type games that make heavy use of AI or other CPU-centric processes.

Does that mean your next gaming PC should have Hyperthreading? The thing is, we are now moving into a mainstream CPU market where six-, eight- and twelve- core CPUs are the norm. So, it’s far better to have more physical cores where possible.

The Simple Answer

Hopefully the above explanation has been clear enough, but let’s break it down to the bottom line:

• If you do professional, thread-heavy work, Hyperthreading matters
• If you are a mainstream user, don’t worry about!
• If you are a gamer, prioritize having more cores in your next build over HT, but get HT in addition if the price is right.

Hyperthreading is a great technology, but it’s not worth the premium for everyone. Now you should know whether that “someone” is you or not!
