What is the difference between the low power version of the processor and the standard voltage versi

The low-voltage version of the CPU, sacrificing part of the performance, consumes less power than the standard voltage CPU of the same model, saves more power, has a longer battery life, and is mostly used in notebooks. Therefore, the low-pressure version and the standard pressure plate are distinguished.

At present, low-power computer accessories are mainly reflected in CPU and memory modules

1. CPU:

1. The naming is different.

Low notebook CPUs often have a U ending in their names, such as i5-4200u, while standard voltage notebook CPUs are usually named with an M ending, such as i5-3230M.

U-series low-power notebook processors typically consume 15W or 28W, while standard-voltage notebook processors typically consume 35W or higher, and low-power CPUs can bring longer battery life.

Low-power notebook processors tend to be clocked at less than 2GHz, while standard-voltage processors are usually clocked at more than 2GHz, and in terms of performance, standard-voltage CPUs are a notch higher than low-voltage CPUs.

For example, the performance of the low-voltage notebook processor i5-4200U is basically equivalent to the performance of the fourth-generation standard voltage i3-3210mi processor, and the performance is basically reduced by one notch.

2. Memory module:

1. Difference in power consumption

Standard DDR3 memory uses a working voltage, while DDR3L memory uses an operating voltage.

For example, a 4G DDR3L 1600 notebook memory will save 2W power consumption compared to DDR3YesSave 4W power consumption.

2. Performance differences

The power consumption of DDR3L memory is 15% lower than that of DDR3 standard memory, and the reduction of power consumption will naturally lead to a decrease in performance. Through testing, DDR3L memory performance is lower than DDR3 memory, but the difference between the two is not too big.

3. Differences

3. Summary:

According to the above, it can be concluded that low power consumption is lower than the standard version in terms of performance, and the battery life will be longer due to low power consumption in notebook applications, but the low power consumption CPU and memory module are higher than the standard voltage; The performance of the standard voltage is higher than the performance of the low power consumption, ** is a little lower, but the battery life will be shortened with high power consumption. It depends on personal preference.

Resources.

The laptop needs to decide whether the low-power version or the standard voltage version is better according to the actual performance needs.

From the performance point of view, it is definitely the standard voltage version of the CPU that is dominant, but a variety of low-power CPUs have developed on the market with their own logic, and low-power CPUs are more suitable for many office notebooks. In terms of game performance, the low-voltage version of the i5 and i7 CPUs can also drive relatively large games, but the performance is weaker than that of the same generation of standard pressure CPUs, roughly equivalent to the level of the previous generation of standard pressure CPUs, for example, the low-voltage i5-4200U is equivalent to the level of i5-3210M.

From the point of view of power consumption, the advantages of low-power processors are more obvious,Aside from the Atom series whose performance can only meet the netbook,U series low-power processor power consumption is generally between 15W 28W,And the standard voltage processor is generally above 35W,Reflected in the battery life is about an hour of battery life gap,The more extreme Core M processorTDP power consumption is as low as,Xiaomi Mi Air equipped with Core M processor can even reach about 8 hours,Complete coverage of a working day's working time。

It is recommended to choose a low-power CPU for office use, which can not only extend the battery life, but also have incomparable advantages in thin, portable and heat dissipation.

No. First of all, the nominal power consumption of the processor is called thermal design power consumption, that is, it is used for the heat sink, and the heat sink is configured according to how many watts of heat. It's not that the power consumption of the CPU is great! This is sometimes a big gap with CPU power consumption......

Secondly, the voltage of the low-power processor will generally be reduced, and the power consumption is actually the voltage and current, and the current requirement is better in the case of frequency increase, to put it bluntly, the low-power processor is to reduce the voltage and current at the same time, thereby reducing the power consumption ......

The difference between the processor of the notebook and the desktop is very large, they will change the architecture to achieve lower power consumption, and the reduction in power consumption must be accompanied by a decrease in performance, the power consumption of the mobile processor is more than 2 3 compared to the desktop, so the natural loss of performance is much lower than the low-power version of the desktop level!

Of course, the above answer is ...... I understand that the low-power version you are talking about is that 605e or something like thatIf you're talking about the E350 450, that's another story.

Here it is. Japanese cars are good, still.

American cars. Good.

Issue. 1: We need to figure out what is low power consumption and what is standard voltage.

Low power consumption: To put it bluntly, it's the processor.

Frequency. Relatively low, so the most direct benefit is:

Low power consumption. Power saving, relatively stable operation.

Standard voltage: with low power consumption.

On the contrary, the main frequency.

High, high power consumption, high power consumption, high heat.

2: Depending on how you use the computer, if it's just an ordinary office plus a mini-game**, the most important thing is that you often carry your laptop out and want the battery to last longer, then choose a low-power laptop.

If you have a laptop fixed at home, or if you use it at work, and often.

Play. Large online games, required.

Use. Make a large one.

Just advise. Use.

normal voltage.

Computer. 3: Computer.

Follow. Cars, like cars, are all hardware facilities. Look at the owner.

What to use, what kind of computer to choose, for different groups of people.

It's all about desktop CPUs, such as Intel's CPU with the word T, and AMD's CPU with E.

First of all, the nominal power consumption of the processor is called thermal design power consumption, that is, it is used for heat sinks, and the heat sink is configured according to how many watts of heat sail hold. It's not that the power consumption of the CPU is great! This is sometimes a big gap with CPU power consumption......

Secondly, the voltage of the low-power processor will generally be reduced, and the power consumption is actually the voltage and current, and the current requirements are better in the case of frequency increase, to put it bluntly, the low-power processor is to reduce the voltage and current at the same time, so as to reduce the power consumption ......

The difference between the processor of the notebook and the desktop is very large, they will change the architecture to achieve lower power consumption, and the reduction in power consumption must be accompanied by a decrease in performance, the power consumption of the mobile processor is more than 2 3 compared to the desktop, so the natural loss of performance is much lower than the low-power version of the desktop level!
