What are the good and bad of ZTE 1 2Ghz dual core phones?

ZTE's low-priced mobile phone is very good for general use. Compare great value. There are U880, U930, U950, and U to choose from, all of which are within 1,000 yuan, and the last three are quad-core machines.

Compared with the dual-core and quad-core of the mobile phone, of course, the quad-core is better, although the main frequency is lower, but the number of CPU cores is four, so the performance is better.

The performance of the CPU is mainly reflected in the following four aspects:

1. Number of cores: At present, most common computer configurations are dual-core, and the mainstream ones generally have quad-cores. But it can't be simply thought that dual-core is worse than quad-core, and there are other comparisons.

For example, the dual-core and four-threaded CPU of the i3 does not have to be worse than the quad-core. The number of cores of a CPU is one of the most important criteria for measuring CPU performance and is greater than anything else.

2. Look at the production process: The production process is also an important factor in judging the performance of the CPU. At present, 45nm CPUs have become popular, the previous generation was 65nm, and there are older 90nm (rare), and the latest mid-to-high-end CPUs have begun to adopt 32nm technology.

32 nm refers to the width of the wire connection between the transistor (referred to as the line width), which simply means that it can be on the same area of the chip"Squeeze"More transistors, more transistors leads to higher performance.

3. Look at the second-level cache: the CPU is in the computer"Run"Sometimes, because it runs too fast, other hardware such as memory can't keep up with it, so CPU manufacturers have introduced caches. Theoretically, Intel's CPU is more efficient, and the CPU can directly retrieve the number when it needs to retrieve some data.

4. Look at the main frequency: In the case that the first three are the same, the quality of the CPU can be judged by the level of the main frequency, mostly.

The CPU frequency is around the top, and the highest is not exceeded now, because if the main frequency is too high, the heat and power consumption will increase accordingly.

The dual-core you are talking about should mean the dual core of the A9 architecture or the Qualcomm S4 Quad core should be the current MediaTek A7 architecture quad core...

Personally, I think that the quad-core is stronger, although it is inferior to the main frequency of a single core and the performance of the architecture, but the advantage in power consumption is quite obvious, and there are 2 more cores, which can make up for the disadvantages of the main frequency of the architecture.

The maximum clock speed is the highest computing speed that this processor can achieve. Generally a little higher than said. For example, it is possible to achieve it at high voltages.

This is similar to overclocking a computer.

Regarding which is better, a 1GHz quad-core phone or a 2GHz dual-core phone, I can tell you for sure that the latter will be better, because his computing power is relatively strong, and there is also a problem involving threads.

For example, if you only open one program, this is a large game, and the others are not opened, then the performance of the latter will be much more prominent than the former, because just one program, the short-term processing power is stronger, and there are more things that can be calculated. If you change to the former, you may get stuck.

For example, if you have a lot of online games, the former will have an advantage.

All in all, in general, you can't open a lot of useless stuff in the background. This not only consumes power, but also wastes memory.

CPU performance is still good for 2GHz dual-core. But the phone also has to look at the random memory RAM. The bigger ones are better.
