Når du leder efter en ny computerprocessor at købe, falder du over tekniske detaljer såsom CPU -basisur eller CPU- boosthastighed. Undrede^(Did) du dig over, hvad det betyder? Mens alle processorer har et basisur (driftsfrekvens), der ligger inden for et par Gigahertz , annoncerer moderne processorer også højere turbo-boost-hastigheder. Uanset om du kigger efter AMD- eller Intel -processorer, viser de alle frem med deres turbo-boost-ure. Her er, hvad Turbo Boost betyder, når det kommer til processorer:

Hvad er processorens basisur?

Du bør først forstå, hvad processorens ( CPU - Central Processing Unit ) basisur er. Basisuret er en processors standardhastighed eller driftsfrekvens. Den måles i Gigahertz og fortæller dig, hvor mange milliarder beregninger den kan udføre på et sekund^{(The base clock is a processor's standard speed or operating frequency. It is measured in Gigahertz, and tells you how many billions of calculations it can perform in one second)} .

I computernes tidlige dage kørte processorer kun på deres basisur (frekvens), hvilket betød, at de havde en fast hastighed, som hverken gik op eller ned. Det betød også, at det var ret nemt at sammenligne processorer for at finde ud af, hvilken der var hurtigst. Generelt var en processor med et højere ur hurtigere end en processor med et lavere ur. For eksempel var en 3 GHz- processor hurtigere end en 2,5 GHz - processor, selvom andre ting såsom processorarkitektur eller mængden af ​​cachehukommelse^(Cache) kunne ændre balancen.

Hvad er processorens turbo-boost-ur?

Moderne processorer har dog også et ekstra turbo-boost-ur, som komplicerer tingene lidt. Hvad betyder turbo boost-uret? Nå, både AMD og Intel skaber i dag computerprocessorer, der kan justere deres hastighed afhængigt af, hvad du laver. Turbo-boost-uret er den maksimale hastighed, som en processor kan køre med^{(The turbo boost clock is the maximum speed at which a processor can run)} .

Du kan sige, at processorer, der kan turbo boost, overclocker sig selv, uden din indgriben. For eksempel kan en processor, der har en standardbasisfrekvens på 3,6 GHz og et turbo boost-clock på 4,6 GHz , såsom Ryzen 7 3700X , køre på 4,6 GHz , når du kører krævende apps eller spil, men kører kun ved 3,6 GHz i resten af ​​tiden. Processoren klarer kørehastigheden på egen hånd.

For at en processor kan nå sit højest vurderede turbo-boost-ur, skal et par betingelser være opfyldt:

• Strøm:^(Power:) Fordi en højere hastighed kræver mere energi, skal dit bundkort være i stand til at levere den nødvendige strøm, for at processoren kan køre på sin turbo boost-frekvens.
• Temperatur:^{(Temperature:)} Den højere mængde strøm, som processoren trækker fra bundkortet, betyder, at processoren også varmer mere. CPU'en^(CPU) skal således have et godt kølesystem, der kan holde sine temperaturer inden for rækkevidde. Ellers, hvis temperaturerne stiger for meget, går processoren i gasspjæld. Det betyder, at den automatisk sænker sin frekvens for at beskytte sig selv mod skader forårsaget af overophedning.
• Udnyttelse:^{(Utilization:)} For at nå sin nominelle turbo boost-hastighed skal din processor have en grund til at gøre det. Hvis dine apps eller spil ikke har brug for mere hastighed end basisuret, har processoren ingen grund til at øge til sit turbo boost-ur. Desuden, hvis ikke alle kernerne i din processor bruges aktivt, er der ingen grund til at aktivere turbo boost.

Desuden har moderne processorer mere end én kerne, som normalt går fra så få som 2 kerner og op til 16 kerner. Du kan blive fristet til at tro, at turbo-boost-hastigheden, der annonceres for din CPU , betyder, at den kan nå den maksimale frekvens på alle dens kerner, men det er måske ikke tilfældet. Nogle processorer kan kun nå det på en, to eller flere af deres kerner, så det er endnu mere kompliceret at forstå, hvad din CPU kan tilbyde. ^(CPU)En ting, du dog kan være sikker på, er, at mindst én af kernerne på din CPU kan nå turbo-boost-hastigheden^{(at least one of the cores on your CPU can reach the turbo boost speed)} på ethvert givet tidspunkt. Den mest almindelige situation er, at når en multi-core CPU når sine turbo boost-hastigheder på to af sine kerner, men de andre kerner bruger lavere ure.

For at gøre tingene forvirrende er Turbo Boost navngivet anderledes af producenterne

Både AMD og Intel har teknologier, der styrer deres processorers base og turbo boost-hastigheder. For deres seneste serie af computerprocessorer (Ryzen 2000 og Ryzen 3000 ) kalder AMD det Precision Boost 2 . Du kan se et par detaljer om det på skærmbilledet nedenfor.

Startende med Intel Core i5 og i7 fra anden generation, bruger Intel Intel Turbo Boost Technology v.2.0 , og til de nyeste Core i7 og i9-processorer bruger den Intel Turbo Boost Max Technology v3.0 .

Hvorfor betyder turbo boost-uret noget (fordele)?

Den største fordel ved at have en processor, der kan turbo-booste^{(turbo boost)} , er, at den gør din computer hurtigere under hård belastning^{(makes your computer faster under heavy load)} . Hvis du kører et videospil eller en krævende applikation, øger din processor automatisk sit boost-ur og giver dig den bedste ydeevne, den kan. Det betyder bedre ydeevne, når det betyder mest.

Desuden er turbo boost en fuldstændig automatisk proces^{(turbo boost is a completely automatic process)} : din processor overclocker sig selv, uden at du behøver indgriben. Det virker bare, så alle får gavn af det, uanset om det er en hjemmebruger uden computererfaring eller en professionel, der arbejder med virksomhedsapps, der kræver stor processorkraft.

Sådan ser du om din processor er i turbo boost-tilstand

Hvordan kan du se, om din processor kører i turbo boost-tilstand? Du kan bruge en specialiseret app, der kan overvåge din CPU , som CPU-Z , eller du kan bruge Task Manager fra Windows.

Hvis du foretrækker ikke at bruge tredjepartsapps, skal du starte Task Manager^{(launch Task Manager)} . Du kan hurtigt åbne den ved at trykke på Ctrl + Shift + Esc tasterne på dit tastatur. Gå derefter til fanen Ydelse^{(Performance tab)} og vælg CPU i venstre side af vinduet. På højre side, under udnyttelsesgrafen, ser du nogle detaljer og realtidsoplysninger om din processor. Blandt dem fortæller Base-hastigheden^{(Base speed)} dig, hvad basisuret på din processor er, og Speed ​​viser dig dens aktuelle hastighed. Hvis værdien Speed ​​(2) er højere end Basishastigheden (1)^{(Base speed (1))} , betyder det, at din processor kører i turbo boost-tilstand. Her er, hvad vi ser, når en AMD Ryzen 72700 processor kører i turbo boost-tilstand:

Og her er et eksempel på en Intel Core i7-7700HQ-processor fra en af ​​vores bærbare computere:

På samme måde kan tredjepartsapps som CPU-Z vise dig den aktuelle hastighed på din processor i realtid. Hvis du kører en krævende app eller spil, og den aktuelle processorfrekvens er højere end dens basisur, som annonceret af producenten, betyder det, at din CPU kører i turboboost.

What is Turbo Boost or Precision Boost when it comes to processors?

When you look for a new computer processor to buy, you stumble upon tеchnicalitiеs such as CPU basе сlock or CPU bоoѕt speed. Did you wonder what that mеans? Whilе all processors have a base clock (operating frequency) that is in the range of a few Gigahertz, mоdern processors also advertise higher turbo boost speeds. Whether you're looking into AMD or Intel processors, all of them show off with their turbo boоst clocks. Here is what Τurbo Boost means when it comes to processors:

What is the processor base clock?

You should first understand what the processor (CPU - Central Processing Unit) base clock is. The base clock is a processor's standard speed or operating frequency. It is measured in Gigahertz, and tells you how many billions of calculations it can perform in one second.

In the early days of computers, processors only ran at their base clock (frequency), which meant that they had a fixed speed, that did not go up or down. It also meant that comparing processors to find out which was faster was fairly easy. In general, a processor with a higher clock was faster than a processor with a lower clock. For example, a 3 GHz processor was faster than a 2.5 GHz processor, although other things such as processor architecture or the amount Cache memory could alter the balance.

What is the processor turbo boost clock?

Modern processors, however, also have a second turbo boost clock, that complicates things a bit. What does the turbo boost clock mean? Well, both AMD and Intel nowadays create computer processors that can adjust their speed depending on what you are doing. The turbo boost clock is the maximum speed at which a processor can run.

You can say that processors that can turbo boost, overclock themselves, without your intervention. For example, a processor that has a standard base frequency of 3.6 GHz and a turbo boost clock of 4.6 GHz, such as the Ryzen 7 3700X, can run at 4.6 GHz when you are running demanding apps or games, but only runs at 3.6 GHz in the rest of the time. The processor handles the running speed on its own.

In order for a processor to reach its highest-rated turbo boost clock, a few conditions have to be met:

• Power: Because a higher speed requires more energy, your motherboard must be able to deliver the power necessary for the processor to run at its turbo boost frequency.
• Temperature: The higher amount of power drawn by the processor from the motherboard means that processor also heats more. Thus, the CPU must have a good cooling system that can keep its temperatures in range. Otherwise, if the temperatures go up too much, the processor goes into throttle mode. That means that it automatically lowers its frequency to protect itself from damage caused by overheating.
• Utilization: To reach its rated turbo boost speed, your processor must have a reason to do that. If your apps or games do not need more speed than the base clock, the processor has no reason to increase to its turbo boost clock. Also, if not all the cores of your processor are actively used, there is no reason to activate turbo boost.

Furthermore, modern processors have more than one core, usually going from as few as 2 cores and up to 16 cores. You might be tempted to think that the turbo boost speed advertised for your CPU means that it can reach that maximum frequency on all of its cores, but that might not be the case. Some processors can reach it only on one, two or more of their cores, so understanding what your CPU can offer is even more complicated. However, one thing that you can be sure of is that at least one of the cores on your CPU can reach the turbo boost speed at any given time. The most common situation is that when a multi-core CPU reaches its turbo boost speeds on two of its cores, but the other cores use lower clocks.

To make things confusing Turbo Boost is named differently by manufacturers

Both AMD and Intel have technologies that control their processors' base and turbo boost speeds. For their latest series of computer processors (Ryzen 2000 and Ryzen 3000) AMD calls it Precision Boost 2. You can see a few details about it, in the screenshot below.

Starting with Intel Core i5 and i7 from the second generation, Intel uses Intel Turbo Boost Technology v.2.0, and for the latest Core i7 and i9 processors, it uses Intel Turbo Boost Max Technology v3.0.

Why does the turbo boost clock matter (benefits)?

The main benefit of having a processor which can turbo boost is that it makes your computer faster under heavy load. If you run a video game or a demanding application, your processor automatically increases its boost clock and gives you the best performance it can. That means better performance when it matters most.

Furthermore, turbo boost is a completely automatic process: your processor overclocks itself, without needing any intervention from you. It just works, so everyone gets to benefit, whether a home user with no computer experience or a professional who works with enterprise apps that require heavy processing power.

How to see if your processor is in turbo boost mode

How do you see if your processor runs in turbo boost mode? You can use a specialized app that can monitor your CPU, like CPU-Z, or you can use the Task Manager from Windows.

If you prefer not to use third-party apps, launch Task Manager. You can quickly open it by pressing the Ctrl + Shift + Esc keys on your keyboard. Then go to the Performance tab and select CPU on the left side of the window. On the right side, under the utilization graph, you see some details and real-time information about your processor. Among them, the Base speed tells you what the base clock of your processor is, and Speed shows you its current speed. If the Speed (2) value is higher than the Base speed (1), it means that your processor is running in turbo boost mode. Here is what we see when an AMD Ryzen 7 2700 processor runs in turbo boost mode:

And here's an example of an Intel Core i7-7700HQ processor from one of our laptops:

Similarly, third-party apps such as CPU-Z can show you the current speed of your processor in real time. If you are running a demanding app or game, and the current processor frequency is higher than its base clock, as advertised by its manufacturer, then it means that your CPU is running in turbo boost.

What is the Turbo Boost or Precision Boost speed of your processor?
