I want to buy a suitable Lenovo brand machine CPU 775 pin

I can tell you for sure: the 945 motherboard supports the full range of CPUs of the Ben 4, including the Pentium D, and the Pentium D920 is certainly a good choice.

You have to determine what chipset your host is based on.

But my experience has taught me that either VIA or SIS.

Then we can tell you what kind of CPU you can use

Overclocking, one of my classmates bought 80 yuan for more than enough to bring Call of Duty 6

775-pin CPU performance ranking ladder chart:Xeon (Xeon) CPU: is a microprocessor produced by Intel, which is used in:"Intermediate range"of business servers and workstations.

Up to eight Xeon processors can share a 100MHz bus for multiplexing on Intel's server boards. Xeon is designed for use on the Internet and for a wide range of data processing services, such as engineering, imaging and multi-data applications that require the rapid transfer of large amounts of data.

Performance metricsFor CPUs, the main indicators that affect its performance include the main frequency, the number of bits of the CPU, the cached instruction set of the CPU, the number of CPU cores, and the IPC (number of instructions per cycle). The so-called CPU frequency refers to the clock frequency, which directly determines the performance of the CPU, and can be overclocked to increase the CPU frequency to obtain higher performance. The number of bits of the CPU refers to the number of bits of floating-point number that the processor can calculate at one time, and in general, the higher the number of bits of the CPU, the faster the CPU will be able to perform calculations.

The main processor families are:

Pentium 4, Celeron D, Pentium D8, D9 series, Pentium E2, Pentium E5, E6, Core E4, E6, E7, E8, Core Q6, Q8, Q9

The Pentium 4 uses the LGA775 interface for the 5 and 6 series, and the classic model has the Pentium.

Celeron D adopts LGA775 interface, including Celeron D 331 and so on.

Uses a 915 chipset.

Besturn D8 adopts LGA775 interface, etc.

Pentium D9 adopts LGA775 interface, etc.

Uses 945 chipset.

Pentium E2 adopts LGA775 interface, etc.

Pentium E5 adopts LGA775 interface, etc.

Pentium E6 adopts LGA775 interface, etc.

The use of G31, G41, P31, P43, P45 Core E6 using LGA775 interface is etc.

The Core E7 uses the LGA775 interface, etc.

The Core E8 uses the LGA775 interface, etc.

Uses G31, G41, P31, P43, P45 chipsets.

Core Q6 uses LGA775 interface, Q6600 and so on.

Uses a 965 chipset.

The Core Q8 uses the LGA775 interface, etc.

The Core Q9 uses the LGA775 interface, and there are 9550 and so on.

Uses G31, G41, P31, P43, P45 chipsets.

The 775-pin CPU spans a lot, including the 775-pin Celeron D, the 775-pin Pentium 4, the 775-pin Pentium D, the 775-pin Core Celeron, the 775-pin Pentium E (dual-core), and the 775-pin Core 2 (all dual-core).

All of them are single-core, without remarks.

Now all CPUs are 775 pins, but maybe Intel will launch the next generation of products in the second half of the year, which is not 775 pins.

Ben 4, Ben D, Ben E, Core E, Core Q are all 775 pins, if you need to upgrade, it depends on the specific motherboard model.

Quad-core Q6600 is good... 1250 in bulk.

The cheap ones are E2160, and the boxed ones are 430

The good ones are E4500, 850

Intel's current full range of CPUs are 775-pin.

I'll add one more.

The best one is the Core 2 QX9770 Extreme.

Core 2 QX9770 Extreme Edition A must
