CPU model problem, what model is this CPU?

Athlon, Core, and Pentium are all series names.

Intel's current CPU main series models are:

Intel Pentium dual-core series, the specific models are:

Intel Pentium dual-core E5200, E5300, E5400, but the main frequency is different, everything else is the same. The default external frequency of this series is 200MHz, the front-end bus frequency is 800MHz, the secondary cache is 2M, the E5 series are the latest 45nm production process, and the old 65nm Pentium E2 series has been discontinued, so let's not talk about it.

Intel Core 2 dual-core series, the specific models are:

Intel Core 2 dual-core E7200, E7300, E7400, the default external frequency of this series is 266MHz, the front-end bus frequency is 1066MHz, and the L2 cache is 3M, all of which are made of 45nm technology.

Intel Core 2 dual-core E8200, E8300, E8400, E8500, E8600, E8 series default external employment is 333MHz, front-side bus frequency is 1333MHz, L2 cache is 6M, and they are all made of 45nm process.

Three-core products, from the four-core shielding one core, the main frequency, the interface.

am2+。The performance is okay.

Looking at the information in the first picture, it seems that it is the Pentium 4 517, which was released in the third quarter of 2005, and now it is no longer valuable, and the motherboards that can be matched are basically broken.

PS: Look at the second row is the brand series, and the third line starts with the model 517.

It dragged on for so long and finally grinded it out The workstation went to ASUS for repair because of a problem with the motherboard, and it is estimated that it will take another week

CPU is a very large-scale integrated circuit, which is the computing core and control unit of a computer.

Previous CPU models were distinguished by frequency, such as P4

In other words, its frequency is, for example, AMD2000+, which means that its best frequency is equivalent to.

However, the current CPUs have canceled the distinction by code frequency, and those AMD5000+ or Intel7750 are just a code name, and the order of production is distinguished by the size of the number.

Generally speaking, there is only one processor with different numbers that means that the large number is an upgraded version of the small number, and it is customary for the latter to increase the frequency of the processor, thereby increasing the main frequency, and the performance is slightly higher than the former, which can be considered to be the latter frequency doubling.

After testing, the quality of a CPU core reaches the standard of 870, the so-called 870! A batch of CPUs are ranked and numbered in turn! The same goes for graphics cards, hard drives, and memory!

The 860 and 870 are contemporaneous products! q3'09

So the 860 is a slightly worse CPU! The 8xx lower limit in the same period!

Speaking of the second generation i3 2100, there is only this model in this series at the beginning! It shows that at least 2100 is the formal standard of i3, and then the technology matures, and there is! It can only be said that it is getting better and better, and it is not necessary to say that the 2100 is a slightly inferior product!

860 and 870 cannot read out the parameters, which can only mean that the clock frequency of 870 is higher than that of 860, 870 is 860.

The 860 and 870 are just the models 8 with it, the Intel 5 series, the 60 and 70 are what I said above.

Core i7 620 Mobile.

2 cores and 4 threads.

Power consumption: 25W3 level cache 4MB

From above, it's the Intel Core i7

Intel Core i7 This one is the CPU

To give you a simple explanation, if the landlord understands, please give it to me.

In the past, there was a law of computers, which said that every 18 months, the performance of a computer doubles, and **decreases by half. This performance refers to the main frequency of the CPU, and it used to be true that the higher the frequency, the better.

Later, the main frequency of the CPU increased higher and higher, and the heat generated became larger and larger, and the bottleneck was encountered! So it's no longer the dominant frequency.

At this time, everyone thought of other technologies to improve the performance of the CPU, and the L1 cache and L2 cache came into being. In previous years, the L2 cache was either none, or 512KB or something, and the current CPU L2 cache has reached 2MB.

There are other techniques that can improve the performance of the CPU, such as the front-side bus frequency and so on.

I hope you understand what I'm saying.

It is better to give it to fish than to give it to fish, the model of the CPU, the frequency doubling, the bus frequency, and the overall performance ranking, please see this**:

The main frequency is indeed the first factor affecting the CPU, but the bus frequency, frequency doubling, nanotechnology, and CPU architecture also deeply affect the performance of the CPU, so some CPU with the main frequency can even do more than the CPU with the main frequency, and it is more expensive than him!
