Koji je vaš omiljeni web preglednik? Da li^(Are) , kojim slučajem, koristite Google Chrome ? Koristite li Chrome 64-bitni ili 32-bitni Chrome? Ako još uvijek koristite 32-bitnu verziju, ali je vaš Windows 64-bitni, trebali biste razmisliti i o prelasku na 64-bitni Google Chrome . Pitate li se koji je najbolji, najbrži ili onaj s manjim zahtjevima sustava? Sve smo se to i mi pitali pa smo odlučili dobiti odgovor na ova pitanja. Proveli smo nekoliko mjerila, izmjerili potrošnju RAM-a^(RAM) , pretražili web u potrazi za informacijama i na kraju smo dobili ovaj članak. Ako želite znati koja je razlika između 64-bitne i 32-bitne verzije Google Chromea^{(Google Chrome)} , čitajte dalje:

Google Chrome 64-bit u odnosu na 32-bit - performanse u mjerilima

Započeli smo testiranjem dvije verzije Googleovog^(Google) web preglednika u nekoliko alata za usporedbu: HTML5 test , JetStream 1.1 , Peacekeeper , Basemark Web 3.0 , Octane 2.0 i MotionMark 1.0 . Svaki benchmark osim HTML5 testa pokrenut je tri puta, a mi smo zabilježili prosječnu ocjenu. Stroj koji smo koristili za testiranje je računalo srednje klase s prosječnim performansama po današnjim standardima: procesor AMD FX8350^{(AMD FX8350)} koji radi na 4,0 GHz , 8 GB DDR3 na 2133 MHz i AMD Radeon R9 270X video kartica s 2 GB GDDR5memorija. Koristili smo Windows 10 Professional verziju 1703 s Creators Update .

Rezultat HTML5 testa^{(HTML5 test)} je pokazatelj koliko dobro vaš preglednik podržava HTML5 standard i njegove povezane specifikacije. Kao što možete vidjeti iz sljedećeg grafikona, 64-bitna verzija Google Chromea^{(Google Chrome)} nudi istu razinu podrške za HTML5 standard kao i 32-bitna verzija. To je za očekivati ​​budući da uspoređujemo različite verzije istog preglednika.

Benchmark JetStream 1.1^{(JetStream 1.1)} pokreće testove kašnjenja koji mjere koliko brzo se web-aplikacije mogu pokrenuti i povećati na vrhunske performanse, te raditi glatko bez prekida. Također izvodi testove propusnosti koji mjere trajnu vrhunsku izvedbu web aplikacija. Najviši rezultati znače veću brzinu i bolje performanse. Kao što možete vidjeti na slici ispod, rezultati koje smo dobili nisu toliko različiti. Međutim, 64-bitna verzija Google Chromea^{(Google Chrome)} bila je 8% brža od 32-bitne verzije.

Zatim smo koristili Peacekeeper mjerilo^{(Peacekeeper benchmark)} koje je starije mjerilo, ali je i danas relevantno za web. Peacekeeper mjeri izvedbu preglednika testiranjem njegovog JavaScript renderiranja i njegove sposobnosti rukovanja uobičajenim JavaScript funkcijama. 64-bitna verzija Google Chromea^{(Google Chrome)} ponovno je pobijedila, s razlikom od 4%.

Sljedeći test koji smo koristili bio je Basemark Web 3.0 . Njime se mjeri sposobnost generiranja objekata u 2D i 3D-u i istovremeno brušenje više CSS operacija. Također govori koliko dobro preglednik podržava CSS3 , HTML5 , Flash i Silverlight te koliko brzo preglednik učitava stranice i šalje zahtjeve. U ovom testu, 64-bitna verzija Google Chromea^{(Google Chrome)} ponovno je bila pobjednik, s maržom od gotovo 6%.

Octane 2.0 mjerilo je koje je razvio i održava sam Google . Ova referentna vrijednost mjeri izvedbu JavaScripta^(JavaScript) vašeg web-preglednika i izvodi niz testova koji pokrivaju najčešće slučajeve upotrebe koji se nalaze na webu. 64-bitna verzija Google Chromea^{(Google Chrome)} uspjela je postići rezultat koji je za gotovo 7% bolji od onoga što je postigla 32-bitna verzija.

Konačno, pokrenuli smo i MotionMark , mjerilo koje se usredotočuje na grafičke performanse. Testovi koje izvodi vizualno su bogati i dizajnirani da naglase grafički sustav, a ne JavaScript . Google Chrome 64-bit imao je performanse koje su bile 16% bolje od njegove 32-bitne verzije.

Google Chrome 64-bit u odnosu na 32-bit - potrošnja RAM-a

Potrošnja RAM^(RAM) memorije jednako je važna kao i performanse JavaScripta^(JavaScript) ili grafike, pogotovo ako koristite sporiji uređaj, s manje RAM-a^(RAM) od prosjeka. Da bismo vidjeli koliko je RAM memorije potrebno 64-bitnim i 32-bitnim verzijama Google Chromea^{(Google Chrome)} , učinili smo sljedeće:

• Koristili smo računalo srednjeg ranga s prosječnim performansama prema današnjim standardima: procesor AMD FX8350^{(AMD FX8350)} koji radi na 4,0 GHz , 8 GB DDR3 na 2133 MHz i AMD Radeon R9 270X video karticu s 2 GB GDDR5 memorije, sve radi na Windows 10 Professional verziji 1703 s ažuriranjem^(Update) za kreatore .
• Instalirali smo Google Chrome 64-bit, a zatim Google Chrome 32-bit , i za svaku od njih otvorili smo iste kartice. Pokušali smo kopirati scenarij iz stvarnog života, pa smo otvorili kartice za svaku od ovih web stranica: Gmail , Facebook , CNN , YouTube , BoredPanda i Digital Citizen - 2 kartice za nas. 🙂
• Za svaku web stranicu koju smo otvorili skrolirali smo njihov sadržaj koliko je to bilo moguće. To je značilo da je Facebook morao nastaviti učitavati sadržaj u svoj news feed sve dok više nije imao što za prikazivati, te je stao sa smiješnom porukom "Imat ćete više priča u News Feedu ako dodate još prijatelja." ^{("You'll have more stories in News Feed if you add more friends.")}U slučaju YouTubea^(YouTube) , nismo ga samo učitali, već smo u njemu pustili i video.

Po našem mišljenju, a nadamo se da i kod vas, sve navedeno treba dovesti do situacije što bliže stvarnosti. Kako bismo provjerili koliko RAM memorije koristi Google Chrome , koristili smo njegovu značajku Task Manager . To je zato što prikazuje detaljnije informacije o svakoj kartici otvorenoj u Google Chromeu^{(Google Chrome)} od informacija koje dobijete u Upravitelju zadataka^{(Task Manager)} u sustavu Windows.

Kada smo koristili 64-bitnu verziju, Google Chrome je pojeo nevjerojatnih 1,19 GB RAM memorije za učitavanje svih kartica koje smo gore nabrojali.

Kada smo koristili njegovu 32-bitnu verziju, Google Chrome je trebao samo 634 MB RAM memorije za učitavanje svih tih kartica.

Kao što možete vidjeti, u stvarnim situacijama, 64-bitna verzija Google Chromea^{(Google Chrome)} treba gotovo dvostruko više RAM memorije koju zahtijeva 32-bitna verzija. Nažalost, to nije dobra vijest za ljude koji koriste low-end uređaje, s nedovoljno RAM memorije.

Ostale stvari koje treba uzeti u obzir u vezi s 64-bitnim u odnosu na 32-bitni Google Chrome u pogledu brzine, sigurnosti i stabilnosti^{(Google Chrome)}

Kada je Google najavio lansiranje^{(Google announced the launch)} 64-bitne verzije Chromea^(Chrome) 2014. godine, podijelili su i neke informacije o tome što korisnici trebaju očekivati ​​od njega. Osim nešto brže izvedbe koju smo izmjerili u benchmarkovima, postoje i prednosti koje se ne mogu izmjeriti s ovakvim alatima za testiranje:

• Poboljšana brzina pri radu s grafikom i videom^{(Improved speed when dealing with graphics and video)} - 64-bitna verzija preglednika Google Chrome^{(Google Chrome)} poboljšava brzinu grafike i videa uključujući YouTube videozapise visoke razlučivosti^{(High Definition YouTube)} . Na primjer, VP9 kodek koji se koristi u videozapisima visoke razlučivosti na YouTubeu^{(High Definition YouTube)} pokazuje poboljšanje od 15% u izvedbi dekodiranja. Kao rezultat toga, brzina je poboljšana, a performanse se povećavaju za 25%, posebno u grafičkim i multimedijskim sadržajima.
• Bolja sigurnost^{(Better security)} - 64-bitna verzija preglednika Google Chrome^{(Google Chrome)} može iskoristiti prednosti novih sigurnosnih značajki koje su uključene u sustave Windows 8.1^{(Windows 8.1)} i Windows 10 . Na primjer, dodaje podršku za ASLR visoke entropije^{(High Entropy ASLR)} (Address Space Layout Randomization ), koji pruža dodatni zaštitni sloj i bolju obranu od tehnika iskorištavanja. ASLR se temelji na maloj šansi da napadač pogodi lokacije nasumično postavljenih područja. Sigurnost^(Security)povećava se povećanjem prostora za pretraživanje. Stoga je randomizacija adresnog prostora učinkovitija kada je više entropije (poremećaja) prisutno u slučajnim pomacima. To sprječava napadača da pouzdano skoči na određenu iskorištenu funkciju u memoriji. Dodatni bitovi prisiljavaju softver da koristi sve resurse za postizanje maksimalne obrane, poboljšavajući postojeće sigurnosne značajke.
• Poboljšana stabilnost^{(Improved stability)} - 64-bitni motori za renderiranje su gotovo dvostruko stabilniji od 32-bitnih motora, kada rukuju web sadržajem. Konkretno, stopa rušenja procesa renderiranja je gotovo 50% manja od one u 32-bitnoj verziji Google Chromea^{(Google Chrome)} .

Kasnije, krajem 2016., Google je objavio još jedan post na blogu^{(blog post)} u kojem je objavio da je 64-bitni Chrome počeo^(Chrome) koristiti Microsoftovu tehnologiju ^(Microsoft)vođene optimizacijom profila^{( Profile Guided Optimization)} ( PGO ), koja čini Chrome do 15% bržim na Windowsima^(Windows) , od verzije 53. Međutim, isto pojačanje dobivate ako koristite 32-bitni, ali samo u njegovoj verziji 54 ili novijoj.

Zaključak^(Conclusion) - Google Chrome 64-bitni vrijedi koristiti

Sigurno je reći da, kada se koristi 64-bitna verzija Google Chromea^{(Google Chrome)} , većina korisnika neće osjetiti nikakvu razliku u svom iskustvu pregledavanja weba. Što se tiče performansi, naši testovi su pokazali da se razlike mogu pronaći. Međutim, još uvijek su vjerojatno premalene da bi se osjetile u svakodnevnoj upotrebi. S druge strane, treba uzeti u obzir i faktor potrošnje RAM memorije. ^(RAM)Kao 64-bitni Google Chromejede otprilike dvostruko više memorije nego njegova 32-bitna verzija, to bi mogla biti teška tableta za progutanje za ljude koji koriste uređaje niže klase. Međutim, na kraju, vjerujemo da dodatne prednosti kao što su poboljšana stabilnost i sigurnost čine ovu nadogradnju vrijednom. To je osobito istinito ako gledate puno videa visoke razlučivosti ili igrate igrice u svom web pregledniku. Ako danas želite prijeći na 64-bitnu verziju Google Chromea^{(Google Chrome)} , idite na ovu stranicu^(page) i preuzmite je od tamo.

Google Chrome 64-bit: Is it better than the 32-bit version?

What's your favorite web browser? Are you, by any chаnce, using Google Chrome? Do you use Chrome 64-bit or Chrome 32-bit? If you are still using the 32-bit version but your Windows iѕ 64-bit, you should сonsider switching to the 64-bit Google Chrome as well. Do you wonder which is best, or the fastest, or the one with thе lesѕer system requirements? Wе аsked ourѕelves all that tоo, so we decided to get an answer tо these questions. We ran several benchmarks, we measured RAM consumption, wе scoured the web fоr information, and we ended up with thіs article. If you want to know what'ѕ different between the 64-bit and 32-bit versions of Google Chrome, read on:

Google Chrome 64-bit vs. 32-bit - Performance in benchmarks

We started by testing the two versions of Google's web browser in several benchmarking tools: HTML5 test, JetStream 1.1, Peacekeeper, Basemark Web 3.0, Octane 2.0, and MotionMark 1.0. Each benchmark except the HTML5 test was run three times, and we recorded the average score. The machine we used for testing is a mid-range computer with average performance by today's standards: AMD FX8350 processor running at 4.0 GHz, 8GB of DDR3 at 2133MHz, and an AMD Radeon R9 270X video card with 2GB of GDDR5 memory. We used Windows 10 Professional version 1703 with Creators Update.

The HTML5 test score is an indication of how well your browser supports the HTML5 standard and its related specifications. As you can see from the following graph, the 64-bit version of Google Chrome offers the same level of support for the HTML5 standard as the 32-bit version. This is to be expected since we are comparing different versions of the same browser.

The JetStream 1.1 benchmark runs latency tests which measure how quickly web applications can start and ramp up to peak performance, and run smoothly without interruptions. It also runs throughput tests which measure the sustained peak performance of web applications. The highest results mean faster speed and better performance. As you can see in the screenshot below, the results we got are not that different. However, the 64-bit version of Google Chrome was 8% faster than the 32-bit version.

Next, we used the Peacekeeper benchmark which is an older benchmark, but it is still relevant to the web today. Peacekeeper measures the browser's performance by testing its JavaScript rendering and its ability to handle commonly used JavaScript functions. The 64-bit version of Google Chrome was the winner again, with a difference between scores of 4%.

The next test we used was Basemark Web 3.0. It measures the ability to render objects in 2D and 3D and crunch multiple CSS operations at a time. It also tells how well the browser supports CSS3, HTML5, Flash and Silverlight and how fast the browser loads pages and send requests. In this test, the 64-bit version of Google Chrome was again the winner, with a margin of almost 6%.

Octane 2.0 is a benchmark developed and maintained by Google themselves. This benchmark measures the JavaScript performance of your web browser, and it runs a series of tests which cover the most common use cases found on the web. The 64-bit version of Google Chrome managed to get a result that's better by almost 7% than what the 32-bit version achieved.

Finally, we also ran MotionMark, a benchmark that focuses on graphics performance. The tests it runs are visually rich, and designed to stress the graphics system rather than JavaScript. Google Chrome 64-bit had a performance that was 16% better than its 32-bit version.

Google Chrome 64-bit vs. 32-bit - RAM consumption

RAM memory consumption is just as important as JavaScript or graphics performance, especially if you are using a slower device, with less RAM than average. To see how much RAM memory is needed by Google Chrome's 64-bit and 32-bit versions, we did the following:

• We used a middle-range computer with an average performance by today's standards: AMD FX8350 processor running at 4.0 GHz, 8GB of DDR3 at 2133MHz, and an AMD Radeon R9 270X video card with 2GB of GDDR5 memory, all running on Windows 10 Professional version 1703 with Creators Update.
• We installed Google Chrome 64-bit and then Google Chrome 32-bit, and for each of them, we opened the same tabs. We tried to copy a real-life scenario, so we opened tabs for each of these websites: Gmail, Facebook, CNN, YouTube, BoredPanda, and Digital Citizen - 2 tabs for us. 🙂
• For each website that we opened, we scrolled their contents as much as it was possible. That meant that Facebook had to keep on loading content into its news feed until it had nothing to show anymore, and stopped with a funny message of "You'll have more stories in News Feed if you add more friends." In the case of YouTube, we did not just load it, but we also played a video in it.

In our opinion and we hope that in yours too, all of the above should make for a situation as close to reality as possible. To check how much RAM memory is used by Google Chrome, we used its Task Manager feature. That is because it shows more detailed information about each tab opened in Google Chrome than the information you get in the Task Manager found in Windows.

When we used the 64-bit version, Google Chrome ate a whopping 1.19 GB of RAM memory to load all the tabs we enumerated above.

When we used its 32-bit version, Google Chrome needed only 634 MB of RAM memory to load all those tabs.

As you can see, in real life situations, the 64-bit version of Google Chrome needs almost twice the RAM memory required by the 32-bit version. Unfortunately, that is not good news for people who use low-end devices, with not enough RAM memory.

Other things to consider about Google Chrome 64-bit vs. 32-bit regarding speed, security & stability

When Google announced the launch of the 64-bit version of Chrome, in 2014, they also shared some information about what users should expect from it. Besides the slightly faster performance we have measured in benchmarks, there are also advantages that cannot be measured with such testing tools:

• Improved speed when dealing with graphics and video - the 64-bit version of Google Chrome improves the speed of graphics and video including High Definition YouTube videos. For example, the VP9 codec used in High Definition YouTube videos shows a 15% improvement in decoding performance. As a result, speed is improved, and the performance increases by 25%, especially in graphics and multimedia content.
• Better security - the 64-bit version of Google Chrome can take advantage of the new security features that are included in Windows 8.1 and Windows 10. For example, it adds support for High Entropy ASLR (Address Space Layout Randomization), which provides an extra protection layer and a better defense against exploitation techniques. ASLR is based upon the low chance of an attacker guessing the locations of randomly placed areas. Security is increased by increasing the search space. Thus, address space randomization is more efficient when more entropy (disorder) is present in the random offsets. This prevents an attacker from reliably jumping to a particular exploited function in memory. The extra bits force the software to use all the resources to obtain maximum defense, improving existing security features.
• Improved stability - 64-bit rendering engines are almost twice as stable as the 32-bit engines, when handling web content. In particular, the crash rate for the rendering process is nearly 50% smaller than that of the 32-bit version of Google Chrome.

Later on, in late 2016, Google published another blog post in which they announced that the 64-bit Chrome has started using Microsoft's Profile Guided Optimization (PGO) technology, which makes Chrome up to 15% faster on Windows, as of version 53. However, you get the same boost if you are using the 32-bit, but only in its version 54 or newer.

Conclusion - Google Chrome 64-bit is worth using

It is safe to say that, when using the 64-bit version of Google Chrome, most users will not feel any difference in their web browsing experience. Performance-wise, our tests have shown that the differences are there to be found. However, they are still probably too small to be felt in daily use. On the other hand, there's also the RAM memory consumption factor to consider. As the 64-bit Google Chrome eats roughly twice as much memory as its 32-bit version does, it may be a tough pill to swallow for people who use lower end devices. However, in the end, we believe that the additional benefits such as the improved stability and security make this upgrade worthwhile. This is especially true if you watch lots of high-definition videos or you play games in your web browser. If you want to switch to the 64-bit version of Google Chrome today, go to this page and download it from there.
