Iibsashada kaadhka sawir-gacmeedka cusub waa mid ka mid ah farxadaha weyn ee lahaanshaha ciyaaraha ama PC kale oo waxqabadkiisu sarreeyo. Waxaad qaadan kartaa kombuyuutar aad hadda leedahay, oo, qayb yar oo ka mid ah kharashka mashiinka oo dhan, waxaad u cusboonaysiin kartaa heerarka garaafyada ee hadda.

Nasiib darro, inkasta oo ay tahay qayb muhiim ah oo ka mid ah waxqabadka ciyaaraha, GPU -gaagu kuma shaqeeyo si gooni ah. Waxay ku xidhan tahay qaybaha kale ee kumbiyuutarka ku jira inay shaqadooda si sax ah u gutaan, ama ma gaadhi karo awoodiisa buuxda. Tan waxaa loo yaqaan "dhalada dhalada" waana tixgalin muhiim ah marka la iibsanayo GPU cusub . Burburka u dhexeeya GPU -gaaga iyo CPU -gaaga hadda jira gaar ahaan waa walaac muhiim ah.

Nasiib wanaag waxaa jira dhowr qalab oo online ah oo loogu talagalay inay kaa caawiyaan inaad ogaato ciladda oo aad ku salayso go'aankaaga taas. Gaar ahaan, waxaanu eegi doonaa qalab dhamaystiran oo laga helo gpucheck.com .

Kahor intaanan qodin tillaabooyinka dhabta ah ee ku lug leh go'aaminta in cidhiidhi uu ka dhex jiro CPU -gaaga jira iyo ^(CPU)GPU -ga mustaqbalka , waxaan u baahanahay inaan si kooban u furno waxa cidhiidhigu yahay qaab la taaban karo.

Waa maxay Saxda Dhalada^{(Bottleneck Exactly)} -CPU-ga ?

Markaad ciyaareyso ciyaarta fiidyaha, qayb kasta oo ka mid ah kombuyuutarkaaga waxay ka shaqaynaysaa qayb ka mid ah nidaamka guud. CPU-gaagu guud ahaan wuxuu mas'uul ka yahay samaynta xisaabinta fiisigiska, waxay u qabataa fikirka ciyaarta AI, waxay maamushaa macquulka ciyaarta, maamusha animation iyo wixii la mid ah. GPU-gaagu waxa uu soo bandhigaa dhammaan muuqaallada aad aragto, oo ay ku jiraan dhammaan fiillooyinka joomatari, muuqaalada ku duudduuban, nalka iyo hadhyada.

Sida cad GPU -gu ma samayn karo qaab ciyaarta la siiyay haddii CPU -gu aanu dhammayn xisaabaadka uu u baahan yahay. Haddii dabeecaddaadu ay mindi ku tuurtay madaxa goblin, GPU -gu ma sameyn karo saameynta haddii CPU aysan u sheegin in mindidu ku dhufatay bartilmaameedka!

Gadaalku sidoo kale waa run. Haddii CPU la dhammeeyo xisaabinta, laakiin GPU -gu aanu dhammayn bixinta qaabkii hore, CPU waa inay sugtaa, laga yaabee xitaa inay daadiso shaqada sababtoo ah hadda ma khusayso.

Xaalad ay qayb ka mid ahi ay sugayso in qayb kale ay shaqadeeda dhammayso ka hor inta aanay u dhaqaaqin shaqadeeda, waxaad leedahay cidhiidhi. Asal ahaan^(Basically) , nidaamka oo dhan waa sida ugu dhakhsaha badan sida qaybta ugu gaabis ah ee silsiladda. Ciyaaraha fiidyaha tani waxay guud ahaan u muujisaa sida heer-beereed xaddidan qaybta gaabiska ah.

Qoorta dhalada ah miyay guud ahaan xun yihiin?

Maya! Dhab ahaantii, waxaa jira ku dhawaad ​​had iyo jeer^{(always )} caqabad ku ah nidaam kasta. Waa dhif iyo naadir in kombuyuutar kastaa si qumman u dheelli tiran xaalad kasta, iyada oo qayb kastaa ay si buuxda u soo jiidanayso awooddeeda. Markaa arintu run ahaantii maaha in nooc ka mid ah cidhiidhigu jiro, laakiin waa dhibaato in heerka ay qaybaha gaabinayaan waxyaabaha xaddidayaan ay tahay dhibaato.

Haddii CPU -gaagu kaliya kuu ogolaado inaad hesho faa'iidada 98% ama 99% waxqabadka ugu badan ee GPU^(GPUs) -gaaga , taasi dhib maaha. Haddii aad kaliya helayso 70% awoodda GPU-gaaga sababtoo ah CPU gaabiska ah , waxaad lacag ku lumisay waxqabadka qalabka ma heli kartid iyada oo aan la casriyeyn.

Haddii GPU -ga cusubi uu bixinayo 100%, laakiin CPU -gaagu 50% oo kaliya mashquul yahay, waxay la macno tahay inaad ku xidhnayd kaadh dheereeya oo aad ku raaxaysan lahayd waxqabad ka sii fiican. In kasta oo, xaaladdani ay tahay mid aad u yar, marka la eego in aan sida caadiga ah u isticmaalno kombuyuutarradayada hawlo kale oo aan ahayn ciyaarista ciyaaraha fiidiyowga.

Markaa codsiyada kale waxaad weli ku raaxaysan doontaa faa'iidada awoodda CPU ee firaaqada ah. Ma aha in la xuso in aad haysato qol aad ku socodsiiso hawlo kale oo dheeraad ah iyada oo aan saameyn ku yeelan waxqabadka ciyaarta. Marka la soo koobo - GPU dhalo waa wanaagsan yahay, cirridka CPU^(CPU) ayaa xun.

Waxyaalaha Dheeraadka ah ee Saameeya Fasiraadda Qoorta Dhalada^{(Affect Bottleneck Interpretation)}

Waxaa jira wax ka badan oo lagu tarjumo darnaanta dhalada marka loo eego kaliya in la yiraahdo GPU X iyo CPU Y waa ciyaar xun. Taasi waa sababta oo ah noocyada kala duwan ee software waxay soo bandhigaan culeysyo kala duwan labada qayboodba.

Ciyaar si fudud u adeegsata hawlaha CPU waxay u oggolaan doontaa GPU -gaagu inuu ku duulo heer kasta oo uu maamuli karo. Kor u qaad jilitaanka degdegga ah ee ^(Load)CPU ama ciyaarta istiraatijiyad dhinaca kale, oo si lama filaan ah CPU -gaaga inta badan aan laga faa'iidaysanin ayaa beddelkeeda kor u qaadaya heerka cabbirka.

Dejinta aad u isticmaashid inaad ku ciyaarto waxay kaloo saameeyaan xisaabintan. Tusaale ahaan, ku ciyaarista xallinta sare waxay saaraysaa culays dheeraad ah GPU -ga , hoos u dhigaya sababtoo ah waxay qaadanaysaa waqti dheer in la burburiyo tirinta pixel sare. Mar kasta oo xallintu sare u kacdo, waxaa yaraanaya cilad-xumada CPU -gu .

Sababtoo ah wali waxay qabanaysaa isla shaqo isku mid ah, laakiin GPU -gu wax badan ayuu qabanayaa. Markaa haddii CPU -gaagu uu ku xaddidayo heerka jir ilaa 60 fireeem ilbidhiqsi marka uu ku ciyaarayo 1080p waxaad wali heli doontaa 60fps 1440p ama 4K, adiga oo u malaynaya in GPU -gaagu uu ku xidhan yahay.

See How Much Your CPU Bottlenecks Your GPU BEFORE You Buy It

Buying a new graphics card is one of the great joyѕ of owning a gaming or other high-performance PC. Yoυ get to take a computer you сurrently own and, fоr a fraction of a whole machіne’s cost, upgrade it to current graphical standards.

Unfortunately, despite being a key component to gaming performance, your GPU doesn’t work in isolation. It depends on the other components within the computer to do their jobs properly, or it can’t reach its full potential. This is known as “bottlenecking” and is a key consideration when buying a new GPU. A bottleneck between your GPU and existing CPU in particular is an important concern.

Luckily there are a few online tools designed to help you detect bottlenecks and base your decision on that. Specifically, we’ll be looking at a comprehensive tool found at gpucheck.com.

Before digging into the actual steps involved in determining whether a bottleneck exists between your existing CPU and prospective GPU, we need to briefly unpack what a bottleneck is in practical terms.

What Is a GPU-CPU Bottleneck Exactly?

When you are playing a video game, every component of your computer is working on some aspect of the overall system. Your CPU is generally responsible for doing physics calculations, it does the thinking for the game AI, runs the game logic, manages animation and so on. Your GPU renders all the visuals that you see, which includes all the geometric wireframes, the textures wrapped around them, lighting and shadows.

Clearly the GPU can’t render a given frame of the game if the CPU hasn’t finished the calculations it needs. If your character has thrown a knife at a goblin’s head, the GPU can’t render the impact if the CPU hasn’t told it whether the knife hit the target!

The reverse is also true. If the CPU is done doing its calculations, but the GPU isn’t finished rendering the previous frame, the CPU has to wait for it, perhaps even dumping the work because it’s no longer relevant.

In a situation where one component is waiting for another to finish its job before moving on with its own work, you have a bottleneck. Basically, the entire system is only as fast as the slowest component in the chain. In video games this generally manifests as a frame rate limited by the slower component.

Are Bottlenecks Universally Bad?

No! In fact, there is almost always a bottleneck in any system. It’s incredibly rare for any computer to be perfectly balanced in every situation, with each component humming along at its full potential. So the issue really isn’t whether some sort of bottleneck exists, but rather whether the degree to which the slower components limit things is a problem.

If your CPU only lets you get the benefit of 98% or 99% of your GPUs maximum performance, that’s hardly an issue. If you’re only getting 70% of your GPU’s potential because of a slow CPU, you’ve wasted money on hardware performance you can’t access without yet another upgrade.

If your new GPU is giving 100%, but your CPU is only 50% busy, it means you could have hooked up a faster card and enjoyed even better performance. Although, this situation is less of an issue, given that we usually use our computers for tasks other than just playing video games.

So for other applications you’ll still enjoy the benefit of that spare CPU capacity. Not to mention having some room to run additional background tasks without affecting game performance. In short – GPU bottleneck good, CPU bottleneck bad.

Additional Factors That Affect Bottleneck Interpretation

There’s more to interpreting bottleneck severity than just saying GPU X and CPU Y are a bad match. That’s because different types of software present different loads on either component.

A game that makes only light use of CPU functions will let your GPU fly at whatever frame rate it can manage. Load up a CPU-intensive simulation or strategy game on the other hand, and suddenly your usually under-utilized CPU is tanking the frame rate instead.

The settings you use to play also influence this calculation. For example, playing at higher resolutions puts more strain on the GPU, slowing it down because it takes longer to crunch higher pixel counts. The higher the resolution, the less of a bottleneck the CPU becomes.

Because it is still doing the same work, but the GPU is doing more. So if your CPU is limiting frame rates to 60 frames per second when playing at 1080p you’ll still get 60fps at 1440p or 4K, assuming your GPU is up to it.

Checking For Bottlenecks With GPU Check

Now that we have the preamble out of the way, let’s actually do a virtual bottlenecking check.

• First, navigate to this page at GPU Check. Now, under first combination, choose the GPU you currently have as well as the CPU you currently have.

• Under desired quality setting, we are going to leave this under ultra, since that’s what setting we want to use in games. If you are aiming for something lower, adjust accordingly.
• Now under the second combination, choose the GPU you intend to buy. Finally, click use same processor.

• Then click Compare.

Let’s look at the results and interpret them. The most important number here is CPU Impact on FPS. This shows how much the CPU is holding back the GPU. With the old card, this figure was 10%, which is considered OK although it should preferably be less.

The new card is held back 20% by the CPU. Which means we are probably better off buying a slightly slower card, overclocking our existing CPU or upgrading the CPU at a later date.

Of course, in real terms this new GPU is between 36% and 39% than our current combination. The Overall Combination score shows us how good this is as an absolute performance combo at ultra settings.

Using this information, you should be in a position to make an informed choice about whether that prospective GPU is the right purchase for you.
