A question about AMD CPU frequency

Generally, the CPU will have an error of about 10 up and down when explaining the nominal frequency.

AMD's frequency nominal is not the actual frequency, and the conversion of the CPU nominal *** and the actual frequency of different cores changes, for example, the actual frequency of the 462-pin Sempron 2600+ and the 754-pin Sempron 2800+ are both 1600MHz.

In addition, it needs to be reminded that the performance of the CPU is now measured not only by the frequency, although the frequency of the AMD processor is much lower than that of Intel, but the performance is not inferior to Intel.

Generally speaking, the results of the CPU-Z test are more accurate, after all, CPU-Z is a professional software for testing CPUs!

CPUZ is accurate, but you don't have to take it seriously.

Then 1200 is your CPU frequency, so it makes more sense.

Because your CPU frequency changes at any time, it may become immediately next time, and no software can be measured.

It's better to use CPU-Z, judging from some data you sent, your CPU main frequency should be , the outer frequency is 100MHz, and the frequency doubling is 12, which is 1200MHz

The frequency of the CPU is standard, and there will be errors! You don't have to care how much.

As long as you know the standard parameters, it's OK

The maximum frequency of AMD CPU all-core is called the maximum frequency of the CPU, which refers to the maximum turbo frequency of a single core.

The simultaneous turbo frequency of all cores will be a little lower than the maximum turbo frequency of a single core. The base frequency is just a parameter to measure the guaranteed full-load performance of the CPU, and now users don't need to look at it, and the current CPU will run at a lower frequency when the load is low, such as a few or two o'clock frequencies.

The highest frequency CPU is very cost-effective, and it is recommended to buy one or two models lower. Sempron 2800+ is a 462 interface that can be plugged in. In addition, who said that the Sshanlong does not have a 462 interface, and the Sempsaurus interface has +.

Frequency distribution histogram:

In the Cartesian coordinate system, the horizontal axis represents the sample data, the vertical axis represents the ratio of frequency to group spacing, and the size of each group of frequencies in the frequency distribution table is represented by the size of the corresponding rectangular area, and the statistical chart drawn from this is called the frequency distribution histogram. The frequency distribution histogram is a few important data methods.

Mean: The area of each small rectangle of the frequency distribution histogram * the sum of the abscissa of the midpoint of the base edge.

Median: Divides the histogram of the frequency distribution into two equal parts of the recessa parallel to the y-axis.

mode: The abscissa of the midpoint of the base edge of the highest rectangle in the frequency distribution histogram.

Addendum: In the graph, the area of each rectangle is equal to: the frequency of the corresponding groups.

The CPU frequency, also known as the default frequency, is the CPU design frequency, that is, the maximum frequency under maximum load. The default frequency on your graph refers to the maximum frequency of this CPU, which is the main frequency. Its main frequency is 3300Hz as shown on the picture

The current frequency refers to your CPU frequency of 1639Hz at the momentWhy does your APU go down to 1639Hz?That's because your APU's energy-saving technology is working.

This energy-saving technology is: full speed when your computer is doing heavy work, what is heavy work? For example, making pictures, such as playing games, such as compressing what files to decompress, what files to decompress, etc., then your main frequency will return to the maximum.

When you're just browsing the web or listening to music, the CPU frequency decreases.

The so-called default frequency is the frequency when the CPU is fully loaded, if you don't open large programs and a lot of things, the monitor can't run at a high frequency all the time, which will reduce the life of the CPU, so the current frequency is the frequency at which the current processor is running!

Silent frequency is the CPU design frequency, that is, the maximum frequency without overclocking, the current frequency is the real-time working frequency, if there are not too many tasks, of course, you don't have to fire at all, right?

One of the two is a network card and the other is a sound card.

Problem description: AMD 3000+, frequency, but not worse than inter(P4.

Or can someone explain? Why is AMD's performance so good at different frequencies?

Or explain how AMD's awesome technology works?

Analysis: 3000+This is called the PR value, which is a reference value used by AMD to compare Intel's frequency performance, compared to Intel's processor, the real frequency of AMD's processor will be much lower, because there is a problem of execution efficiency. Let's take a simple example.

Because Intel stretches the internal assembly line of the processor very long, it needs to improve the performance by increasing the frequency. AMD's processors can complete more tasks in one computing cycle, so they can achieve relatively high performance at lower frequencies.

Another point to note is that the latest Inter "Core" series CPUs have overcome the weakness of high frequency and low performance, and the performance at the same frequency has surpassed AMD's CPUs, which can be said to be a turning point for Inter.

Intel is all too common to say if it's P4 or even.

That generation architecture problem. It's easy to boost the frequency of Intel. But the performance is poor.

As a result, it can only be compared with the AMD K8 core Athlon 3000+ Athlon 3000+ is actually only about about the same frequency.

Of course, the world is different now. Intel's Core series since the P3M architecture has been improved。。。

The frequencies are generally lower than AMD's Athlons, but the performance is not bad at all. led to the once high-end speed dragon price reduction of 1000 yuan overnight...

Therefore, if the CPU is the same architecture, it mainly depends on the main frequency and cache front-side bus.

If the CPU architecture is different, then it depends on the performance evaluation. It's not that the main frequency is high, the speed is fast.

Intel's new i-series The lowest i3 530 frequency is not high, but its architecture is advanced, and it can kill all the E-series dual-core CPUs of its own Core 2 cores in seconds, and the lead is not small.

I suggest that the landlord take a look at the hardware evaluation and make up for the basics.

The QX9650 of the Core 2 in it can have been extinguished by the AMD family a long time ago, and there is no need for the i series to shoot. -So the architecture of the Core 2 is so advanced that it will kill A, but in terms of cost performance, will it be much higher than AMD's.

Since you understand it so well. What else do you want to ask?。。 How to price is entirely a business act. Manufacturers will formulate a reasonable ** according to the performance and positioning of their own CPUs.

Why AMD is now dual-core** very cheap, and the 3-core is against the Core dual-core. Use 6 cores to deal with i5 and** have to be a little bottom. Of course, motherboards are also relatively inexpensive.

It's not that the performance is not bad. Good value for money though. But on the high-end, it is not Intel's opponent at all.

In particular, the foreign DIR market is generally a high-end market. The characteristic of our country is the pursuit of cost performance. Many foreigners are looking for the highest performance.

I believe. If history plays out again. AMD has come up with a strong performance. I will still adjust the ** very high. The Athlons of the year are an example.

By the way, quote below. I'm talking about i3 is a second all on the dual-core, including the intel home。。。 Don't get me wrong, he's just a dual-core CPU.

It also depends on the process architecture and caching.

In the P4 era, AMD's architecture is good, so AMD's CPU runs faster than I in the same period (P4's high frequency and low energy are known to everyone on earth).

That's the previous P4 architecture is not good, CPU depends on the architecture, cache, number of cores, production technology nm, main frequency, bus frequency, on the whole. The current Core 2's QX9650 can already destroy the AMD family, and there is no need for the i series to shoot.

It's very simple, I'll calculate it for you: memory frequency = CPU external frequency x (memory clock: external frequency) x2, simply put, DDR800 = 200 external frequency x 400 200 x2, for example, how did DDR2 generation 533 come from.

AMD generally doesn't have the kind of bottlenecks that Intel has. As long as the data transmission and bus transmission are matched, it will do.

The external frequency of the CPU is irrelevant to the frequency of the memory, the CPU processes data, the memory stores data, and the larger the memory, the busier the CPU.

It doesn't make much sense to explain it on the detail page, and the next professional software has been tested to know it, hehe.

What money buys what hehe.

1500+ The actual frequency is 133MHz x 10 (1333MHz);

1600+ The actual frequency is 133MHz x (1400MHz);

1700+ The actual frequency is 133MHz x 11 (1467MHz);

1800+ The actual frequency is 133MHz x (1533MHz);

1900+ Actual frequency is 133MHz x 12 (1600MHz);

2000+ The actual frequency is 133mhzathlonxp processor nominal frequency and the actual frequency conversion calculation formula:

Nominal Frequency = 3 * Actual Frequency 2-500

Actual frequency = 2 * nominal frequency 3 + 333 x (1667MHz);

The 2100+ actual frequency is 133MHz x 13 (1733MHz);

2200+ The actual frequency is 133MHz x (1800MHz);

2400+ The actual frequency is 133MHz x 15 (2000MHz);

The 2600+ CPU has two external frequencies, please check which frequency you want to use before adjusting.

The 2600+ actual frequency is 133MHz x 16 (2133MHz); The 2600+ actual frequency is 166MHz x (2083MHz);

The actual frequency of the 2700+ is 166MHz x 13 (2167MHz.)

4000+ 5200+ is just the model marked by AMD 4000+ 90nm nm is 2,2g 65nm is The frequency is not calculated It is set at the factory, the doubling and external frequency, the landlord can only view it through CPU-Z.

Generally, CPU-Z detection is a more authoritative standard, as for the other suggestion, ignore it.

Second, the bandwidth of memory and CPU and HT are generally 5 times that of the external frequency, according to the ** you provide, your current memory can fully make your CPU fully perform.
