Do CPUs that support hyper threading improve the performance of a computer?

Hyper-threading technology is really just a gimmick for processor manufacturers. Regardless of how much hyper-threading technology can theoretically improve, there are very few applications that can support hyper-threading technology ...... todayBasically, they are biased towards graphics, ** processing and other professional software, and game software is rarely supported. The application software is also only Office

2000、office

XP, etc.

That's up to your CPU! The higher the CPU performance (not performance), the greater the role of HT (Hyper-Threading Technology)!

Now out of the i7, high efficiency, plus HT, performance that is called one.

Strong!!!

It makes no difference.

Hyper-threading is only useful for programs that support multithreading.

Hyper-threading is also a virtual dual-core, let me explain.

Single-core is equivalent to.

1 cook. Serve a pot.

Dual-core equivalent.

2 cooks. Serve one pot each (2 pots).

Hyper-threading is comparable.

1 cook. Serve 2 pots.

Hyper-threading technology uses special hardware instructions to simulate two logical cores into two physical chips, so that a single processor can use thread-level parallel computing, which is compatible with multi-threaded operating systems and software, reducing the idle time of the CPU and improving the operating efficiency of the CPU.

If you're on the board.

CPU supports hyper-threading, that must be improved, you can look at task management, it will show the usage of 2 CPUs, the same level of CPU, of course, the sure block of hyper-threading technology.

No. The number of threads will naturally affect the speed, so it seems that the number of threads should be set as high as possible, which is wrong. Suppose that data is transmitted from the server to the user, the user and the server are compared to two small islands, and the number of threads is compared to the bridge between the two small islands.

However, if the bridge is built more than the two parties can bear, the user will not be able to accept the data of other servers, and the server will not be able to transmit data to other users, so the number of threads depends on the specific situation of the server and the user.

The CPU hyper-threading feature allows applications to use different parts of the chip at the same time. While a single-threaded chip can process thousands of instructions per second, it can only operate on one instruction at any one time. The hyper-threading technology can enable the chip to be multi-threaded at the same time, so that the chip performance can be improved.

In the processor with hyper-threading technology, there are also two physical cores, but with the support of hyper-threading technology, the independent physical cores are simulated into two logical cores, so that they have the ability to process four threads at the same time, which is the so-called "virtual quad-core".

In the official introduction of Intel, the performance of hyper-threading technology has been improved by 40%, but in actual use, the improvement is not so large, and it is quite good to increase it by 20%-30%.

Introducing hyper-threading technology:

Hyper-threading technology is Intel's unique technology, which aims to enhance the multi-threaded processing capability of the CPU, and the CPU can theoretically only handle one thread at a time per core, the dual-core CPU can handle two threads at a time, and the quad-core CPU can handle four threads at a time.

The instructions processed by the core in actual work are very complex, for example, some instructions need to be executed by the results obtained by other instruction operations, so there will often be threads "hanging and waiting" in operation, and at this time the core is idle, hyper-threading technology is to make full use of the idle time of the core to process another thread, and use the core resources as much as possible, so as to achieve the purpose of a single core to process two threads "at the same time".

Hyper-threading technology has very limited improvement in the multi-threading processing ability of the CPU, and the best way is to increase the number of CPU cores.

Hyper-Threading technology requires high frequencies to support, and if the frequencies are not high enough, the performance will be reduced, so the Core 2 series did not adopt this technology, and it was not re-enabled until the Core i series.

According to Intel's official statement, turning on hyper-threading will improve performance by 30%.

The i5 itself is a product of the i7 shielded hyper-threading. First of all, i7 is better than i5 performance is certain,It can be seen from the pricing,i5 and i7The price difference is about one-third,I don't think there is anyone better than Intel who knows its own CPU performance。

Good performance is the biggest advantage, and it doesn't get much more revealing than that. As for the number of threads, too much is useless, and in the end it depends on the overall performance. Is the i52500K weaker than the i72600 when overclocked to 5G?

I think two cores are enough if the performance is strong enough. Because no matter how many programs are running at the same time, only one of them can be used as the main program, and the others can be counted as running in the background. One of the cores of a dual-core CPU is used to run the main program, while the other programs are run by the other core.

As long as the performance of a single core is strong enough, both the foreground and background programs can be guaranteed to run at full speed, but the current CPU can't do that, so the number of cores needs to be increased to meet the demand. In addition, new programs are emerging all the time, and the requirements for CPU performance are endless.

The key is what multi-threading is used for, multi-threading is the core of the software virtualization, and ultimately undertakes the calculation, or relies on the physical core for lighter and more open loads, multi-threading can improve the ability by up to 40%, but most multi-threading can improve performance by 20%-30% in ordinary loads.

If it is an application with poor multi-threading optimization, there is not much improvement, such as i5 quad-core four-thread and i7 quad-core eight-thread, overclocking the same frequency, in many games, i7's multi-threading does not help much, the game frame rate is not much different Even i7 games with a lower frame rate than i5 at the same frequency have.

The speed of multitasking is fast, for example, if you play an online game, you can play 8 numbers, and if you operate it, 4 cores and 8 threads will be much faster than 4 cores and 4 threads, and the response will be smooth.
