CPU technical issues, CPU architecture issues

90nm and 65nm refer to the manufacturing process.

In other words, 90nm uses 90nm copper wire.

65nm uses 65nm copper wire.

The finer the copper wire, the higher the requirements for the production process.

The main frequency is how fast the guy can run.

The doubling is how many times this guy can run.

The external frequency is just how fast you want this guy to run.

The core is what this guy is made of.

The name of the core is the core.

To use an analogy, let's take an Formula 1 car

1.The main frequency of the CPU is like the engine exhaust or power of the F1 car; The CPU architecture is like the aerodynamic design of the body of an F1 car;

2.Today's F1 cars only use liter V8 engines with more than 700 horsepower; Before 2005, the V10 engine was used, with more than 900 horsepower. But now F1 cars are not slowing down or even faster because the engine is less powerful!

This is because the aerodynamics of the body are even better.

3.It's the same with CPUs, Intel's CPU architecture is significantly better than AMD's, which leads to why Intel's low-clock CPUs are faster than AMD's high-frequency CPUs. For example:

The Intel i7 920 is much faster than AMD's Phenom II X4 975, despite only being clocked (and turbo clocking).

The simplest thing is that the structure of the chip's internal CPU is different from the excuse for connecting the external to the motherboard.

1. You don't know all your questions. Dual-core without P4 architecture, negligible.

The speed does not depend on the main frequency, and the main frequency can only reflect the speed of the homogeneous CPU. Different architectures cannot be compared together. It's like 100 dollars in the U.S. dollar and 100 yuan in the Japanese dollar have different purchasing power.

The speed can be measured by third-party testing software such as Super Pi as a reference for processing speed.

104W 46 seconds, E2140 104W 35 seconds.

Based on this parameter, the e2140 is 30% faster than the single-core speed by default. Counting the dual-core bonus, that's 160% faster

2.Hyper-threading is the virtualization of the CPU into 2, which can be seen as 2 50%. Acceleration when dealing with 2 tasks less than 50%. However, in the face of the CPU load task of video suppression, there is no acceleration effect.

3.For example, the i3 350 is now more popular. This CPU is dual-core hyper-threaded emulating 4 cores.

Let's assume that the default dual-core hyperthreading speed is 100

With hyper-threading turned off, the dual-core speed is still 100

Turn on hyper-threading, turn off a core (become single-core hyper-threading to simulate dual-core) and the speed is 50

This depends on your software support does not point out the dual-core, if it is not supported, it is a single-core fast, but this is completely based on the assumption of the landlord to answer, in fact, the landlord said "in addition to the exact same u" does not exist in reality! Let's make this clear! The single core is definitely P4, the Core has never produced a single core, and the dual core is definitely the Core.

1.Check whether the CPU is installed correctly, there is a small "triangle" pattern on the CPU slot, which corresponds to the small "triangle" pattern on the CPU.

2.Check whether the cooling fan is installed in place, check whether the screws are tightened, and twist lightly until it cannot be screwed; Buckle type, to the radiator level, tightly combined, no abnormal sound shall prevail.

3.Check whether the CPU cooler fan power plug is properly connected.

4.Check whether the main power plug and auxiliary power plug of the motherboard are connected properly.

5.Finally, check whether the motherboard accessories are connected normally.

Check to see if your sliver is compatible with your CPU (pay attention to the frequency of the sliver).

Can the hardware self-test? Still nothing.

Is your CPU plugged in? Is silicone grease smeared?
