CPU Basic Intro

Many of my friends are so confused about what kind of CPU they should buy? How to tell if a CPU match our needs? What factor should we consider? I list the following considerations you can refer to: ---1-1

1.High clock rate v.s. Multiple cores

Let's start with simple and rough suggestion: gamers need high clock rate & designers need multiple CPU cores. But why? Most of time, one main core deal with most tasks and the rest slightly supports it when computers are used for gaming. So the efficiency of cores plays a more critical role. But if you perform tasks regarding design and video editing, these actions are relatively related to multiple core processing. So even if you have multiple-core CPU but your software doesn't need that, your CPU would not be fully used. In summary, multiple-core CPU is not for sure the best. Likewise, high-clock-rate CPU is not the most ideal choice either.


These technologies mean when heat can be allowed to dissipate, CPU's core speed can rise to over the base frequency.

Which CPU Brand Is Recommended? Intel Or AMD?

Intel's and AMD's history

Many people ask which brand of CPU should they choose, Intel or AMD? Intel, for a long time, provides constant stability but is expensive. In contrast, AMD's products are cheap. So which one is better? I think there is no better one because it depends on your needs. But let's talk about these two brands' pros and cons. Starting with AMD, it used to be a CPU company that surpassed Intel. However, its product performance later lost its position in the market. Thereafter, its product series FX is definitely not recommended because their performance is low, they have so many problems, and they are too hot. There is nothing good about them. However, AMD's situation is totally different. Its recent product RYZEN's performance, because of its changed CPU structure, become as almost efficient as Intel's and are still cheap! Moving to Intel, since its Core i series was invented, has no fierce competition and has been innovating its product. Many people describe Intel as toothpaste. Every innovation of its performance is as with a squeeze of toothpaste. This is due to its cost reduction of heat sink medium "silicon" replaced from solder. However, it leads to a negative effect: higher heat. As a result, Intel's CPU temperature becomes higher than AMD's RYZEN. What's worse, it makes lots of noise. Therefore, it's hard to say Intel has an absolute advantage anymore. I would say now these two brands' competitivenesses are Intel >= AMD.
Brand Intel AMD
Performance wonderful great
Cost Performance Ratio average high
Heat Sink noisy, the ability to discard heat is underperformed quiet, the ability to discard heat is efficient
stability high average

Suggestion for beginners:

If you are hesitating to buy AMD or Intel, I wanna give you some advice on your decision. You can consider 1. usage of your computer 2. budget If we have the budget of Intel double-core CPU, we can buy AMD 4-core CPU or even 6-core CPU. So in terms of cost performance ratio, AMD is higher. In the past, I indeed assembled some computers, especially those for business purpose, with AMD's CPU. They are really cheap!! But if you computer is used for word processing, I recommend you to choose Intel because its stability and durance is better. I think its CPU is durable and at least so far there is nothing wrong with it. Although its warranty period is 3 years, it is basically durable for 5 years. In summary, I recommend that computers for word processing and basic functions can be installed with Intel i3 and that computers for design and games can be equipped with Intel i5 or i7. But if you are a gamer and care much about cost performance ratio, you should choose AMD's CPU as a part of your computer. After all, it's cheap, quiet, and has a low heat sink temperature.

Suggestions for pros:

Intel Intel's products lines can be classified as Core i, Pentium, and Celeron. Among these lines, Core i can be divided into i3/ i5/ i7/ i9 series. Celeron: (double-core & low clock rate), a low-end processor. Pentium: (double-core resembling four-core & average core speed), suitable for word processing Core I3: (four-core & high clock rate) Core I5: (six-core&average clock rate), suitable for intermediate gamers. Core I7: (six-core resembling 12-core & high clock rate), suitable for professional gamers. Core I9: (eight-core and 16 threads), expensive but performs efficiently How to read Intel's naming pattern? Intel CPU Intel: company name Core: brand i7: stands for difference in performance. Generally, the performance ranking is i9>i7>i5>i3. But it also depends on what your computer is used for. 6700: model number. 6 stands for the sixth version. 700 means product specification. If the last three digits become higher, the product is improved better. The last English character: stands for product line suffix. Different English characters have different meanings. K - unlocked. This kind of CPU is suitable for gaming but is more expensive. X - means the best! This kind of CPU is featured as the best performance but is the most expensive one. U - ultra-low power. Usually for thin laptops, such us Ultrabook. T - power-optimized. Battery is optimized and energy-saving AMD While AMD couldn't compete with Intel before, its RYZEN series recently released has breakthrough in performance and energy efficiency. Its price is reasonable, so it could be a good deal!(RYZEN has no integrated GPU) This series includes R7/R5/R3/APU. R7: (8-core resembling 16-core & clock rate could be low or high), is suitable for game and online streaming. R5: (4/6 core & clock rate could be medium or high), considering cost performance ratio, it fits the need of professional gamers. R3: (4-core & average clock rate), is suitable for intermediate gamers and word processing. How to read AMD's naming pattern? AMD CPU AMD: company name Ryzen: brand 1800: model number The last English character could mean: X: represents the technique of XFR, namely TURBO upgradation. It could overclock depending on processor temperature. S: low energy efficiency and has integrated GPU
