Another disadvantage is that the instructions have to be split up to decide which core will execute them and the results have to be merged together again at the end, which slows the processor down a little. The most commonly used instructions and data are stored in the cache so that they are close at hand. The bigger the cache is, the more quickly the commonly used instructions and data can be brought into the processor and used. There are three main factors that affect how quickly a CPU can carry out instructions : clock speed cores cache Clock speed CPUs can only carry out one instruction at a time.
Cores A CPU is traditionally made up of a processor with a single core. They allow more dynamism and an easier flow when running things on your computer. Today, even smartphones have CPUs with multiple cores. Multi-core CPUs appear faster because they are able to take a much larger amount of workload than their single-core counterparts. They are very reliable at removing congestion. Think of them as runways at an airport.
The more of them you have, the easier it will be to get planes on the ground. Higher Clock Speed vs. Ok, so you now understand the benefits of a higher clock speed and the performance boosts more cores can offer. Do you go for a processor with a lower clock speed but more cores? Or one with more cores but a lower clock speed? Is a 12 core 3. These are the questions we will help you answer today. First off, if possible, you want to go for the one with the highest clock speed and the highest amount of cores.
But what does this all mean? Clock speed, multi core, hyper-threading, dual processor systems. Hopefully this will help you decide which processor is right for your system.
More cores, slower clock speed Pros Applications that support multi-threading will greatly benefit from having a higher number of cores at their disposal Increasing the amount of cores in your CPU is a cost effective way of increasing performance Multi-threading support for applications will continue to improve over time You will be able to run more apps at once without seeing performance drops Great for running multiple virtual machines Cons Lower single threaded performance than a higher clock speed processor Fewer cores, higher clock speed Pros Better single threaded performance Lower cost option Cons Fewer cores to split between applications Not as strong multi-threading performance The best thing to do in most cases is to look into the support your applications of choice provide for multi-threading.
A Quad Core at 2. This question comes up very often: For a given application, is it better to use a Dual Core at 3 GHz or a Quad Core having a lower frequency, as they are often offered at the same price? Until last year, the typical answer was: For applications running in parallel multi threaded as video encoding, file compression, Quad Cores proved to be the outstanding and it is always true. For gaming, however, the response was different: the games do not use all 4 cores of a quad, with rare exceptions such as Supreme Commander or GTA 4, it was better to take a Dual Core at 3 GHz or more.
But in , things have changed: 2 factors have change the rules for the Quad Core and games: Turbo mode from the new Intel I5 and I7 Core using the socket can automatically increase the frequency when just one or 2 cores are activated, depending on the applications.

While some instructions can be completed in one clock tick, it could, for instance, take four ticks to complete a multiplication operation. This would turn a processor that can, for instance, add at 4 GHz into one that multiplies at an effective speed of 1 GHz. The three factors identified here work together to determine how fast a given processor will operate.
Sixty-four-bit chips work on twice as much data at once as bit chips, giving them a significant performance boost. Processors with faster external clocks can also exchange data with the computer faster than those with slower external clocks. Finally, processors with more efficient instruction sets that can do more work in fewer clock cycles run more quickly than those that need more cycles to finish an instruction.
Once you've made all of those factors equal, compare processors to see which is faster by looking at the internal clock speed's gigahertz rating.
