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. For example, Core i5 runs at 2. According to a test performed by Hardware Magazine No. The answer is clear in Opt for Quad Core, preferably with Hyper Threading, whatever your applications! It all depends on how many pieces each task can be split up into.
In such a case, having the 8-core CPU I mentioned earlier would give you an advantage. If you use multi-threaded applications which require lots of multitasking, place a priority on the number of cores in your CPU.
Should you desire something more straightforward like gaming, you may not need a whole lot of cores, but would want to have as much clock speed as possible.
Business Simulation in Server CPU Models In today business' calculation, then we'll, all meaninglessly seem, would consider and talk about money, right? How it would benefit us more and more. That is relevant and acceptable, indeed. Why would such 'multi cores' cost us a lot? Yes, because parallel process is very expensive not just only in its technology. Price would never lie. So, we have to carry on with the economical Xeon E3 right? Absolutely Bold Yes for the economical. It may be tempting to buy a processor because it advertises a fast clock speed.
Clock speed refers to the number of cycles that a processor executes per second. A cycle is a unit of measurement during which a processor executes instructions.
If you see a processor that has a rating of 3. You may have seen the terms dual-core or quad-core when reviewing processors. A dual-core chip consists of two processors while a quad-core chip contains four. Like their single-core counterparts, multi-core processors also perform faster when they have higher clock speeds.
Store technicians can offer purchasing advice if you visit electronic stores, while online review sites can help when you shop online. A faster processor performs simple tasks more quickly than a slow one and it makes sophisticated applications quick enough to be practical.
The processor itself is not the only factor involved in a computer's performance however, memory and hard drive speed also come into play. In the computer, a master timing circuit called the "clock" drives the processor. The first microprocessor, the Intel , had a clock speed of kHz, whereas modern examples run at about 3GHz. Although the clock frequency sets the processor speed, you cannot increase the frequency indefinitely; at some point the circuits can't keep up and the processor stops working.
Also, higher speeds produce more heat and overheating may become a major problem. A faster processor can run more sophisticated software and a greater number of tasks overall.
