【 Weak current College 】 how to view computer configuration is good or bad


For many beginners how to view your computer configuration is good or bad is a tangled, even sometimes there are still some misunderstanding, in order to let everyone on the hardware has a more in-depth understanding, here is my contribution is your own.

Motherboard

A look at the number of CPU cores

Now the mainstream is a dual-core, single-core (such as Pentium 4) has been discontinued, high-end, four-core.

Second look at the production process

Currently 45 nm CPU already popular, the previous generation is 65 nanometer, there are more old 90nm (rare). Production technology of 45-nanometer is the transistors and wires wiring between transistor's width (width), in short it is possible in the same area of the chip can squeeze more transistors, more transistors are associated with higher performance. Even if the number of transistors without increasing the size of the chip can also be a corresponding decrease, so power consumption and temperature can be much lower.

3 see the L2 cache size

CPU is the computer "run" the fastest, sometimes because it runs too fast, resulting in additional hardware, such as memory to keep up with his rhythm, so CPU manufacturer introduces caching this thing. See the L2 cache size to determine CPU is good or bad is intended for Intel CPUs, because Intel CPU on L2 cache dependency is relatively large, INTEL's CPU L2 cache key used to store data, while remaining at the level of the cache is the L2 cache of address, in the L1 cache are generally classified in these data, for example on the CPU needs A-Z, access these data directly from the L1 cache, in number of the access to data on the line, so to speak, like the L2 cache is a book's content, level cache is a directory of the book, which is why INTEL CPU L2 cache is particularly large, but especially small L1 cache. While AMD CPU design and Intel, AMD CPU level cache is used to save the most frequently used data and L2 cache is stored themore commonly-used data, so AMD CPU level cache and L2 cache almost. In theory, Intel's CPU efficiency higher CPU requires access to certain data of direct access numbers.

4 see the clock speed

In the previous three have the same case, you can judge the frequency of CPU is good or bad, most of the CPU clock speed is around 2.0GHz-3.0GHz now highest nor exceed 4.0GHz, because the clock speed is too high, heat and power will become larger.

Video card:

Current market graphics chip (GPU) producers have the NVIDIA and ATI both, that is, people usually say N card and A card. GPU video card status equivalent to the computer's CPU. We often say NNIDIA Geforce and ATI HD and is a series, Geforce to now has ten generations, the General said the video card model and when not to add this. Video card manufacturers is too much, but are used in the above two chips.

See the video card or bad main see [graphics chip, SP unit, manufacturing process, the core frequency], [memory frequency, Hin? * assertion li yu long meditation ⑾ source for ⑾ source ji Yuan naphthalene (ranking order, the more the previous more), specific points to be seen how the video work.

Motherboard:

The main watch chipset motherboard, Intel platforms like the common chipsets will not, without set out with P55, P45, P43, etc., with integrated video common G41, G43, G45, set display is the beginning of G. AMD platform motherboards now the mainstream is AMD7 Series chipsets, but also with G is with set out, for example 780G, 785G, 790G, 790GX, etc. And graphics see the motherboard is also working to specific look.

Other:

Hard disk rotational speed are now on the desktop computer, notebook 7200 RPM is 5400.

Memory frequency mainly in order to meet the CPU bandwidth line, for example, to use the CPU E5200, FSB (front side bus frequency) is 800MHz, bandwidth is 800MHz× 64 ÷ 8 = 6.4GB/s, if the CPU is overclocked, when the memory with a memory DDR2800MHz frequency to meet the bandwidth requirements for the CPU. If the E8400 CPU used, it is the FSB 1333MHz, in memory of a DDR2800MHz frequency memory will not be able to make full use of the CPU performance, time's up for dual-channel, two 667MHz frequency memory group dual channel just to meet the demand, if the E8400 overclocking is equipped with two 800 dual channel memory group.
