The main basis for measuring the value of microcomputers is "performance-price ratio". Performance-to-price ratio, referred to as "cost-effectiveness", is the proportional relationship between the performance value and price value of a product. It is a quantitative measurement method that reflects the affordability of an item. The specific formula is "cost-effectiveness = performance/price". In the process of purchasing a certain product, it is more or less necessary to understand that the product is of good quality, low price, and cost-effective; therefore, cost-effectiveness is an important indicator when purchasing a product.

The main basis for measuring the value of microcomputers is "performance-price ratio".
The price/performance ratio is the ratio between the performance value and the price value of the product. It is a quantitative measurement method that reflects the affordability of the item. The full name of cost-effectiveness is performance-price ratio, which is a proportional relationship between performance and price. The specific formula is:Cost-performance ratio = performance/price.
Usually there is no comparison or less opportunity to compare on the same performance basis. Cost-effectiveness should be based on your product performance requirements, that is to say, meet the performance requirements first, and then discuss whether the price is appropriate. Since cost-effectiveness is a proportional relationship, it has its own scope of application and particularity, and cannot be generalized.
In the process of purchasing a certain product, you need to know more or less that the product is of good quality, low price, and cost-effective. Therefore, many customers regard cost-effectiveness as an important indicator when purchasing products. Its reasonable use will allow people to buy cheap and high-quality goods.
Loophole:
When people buy products, they will choose products with high cost performance. However, the price-performance ratio of a product should be based on the same performance, that is to say: if there is no identical performance as a basis for comparison, the price-performance ratio is meaningless.
There is a big loophole in the price/performance ratio. According to the formula of cost-effectiveness, we can know that cost-effectiveness is not a fixed value, but a proportional relationship. Generally speaking: high cost performance, same performance, low price; high performance, same price. Low cost performance, same performance, high price; low performance, same price.
But the price/performance ratio is not static.
A typical example of increased cost performance is today’s electronic products and information products. With the advancement of science and technology, the performance of electronic products has increased rapidly. However, due to the improvement of manufacturing level and the decrease of cost, the price of the same type of products has continued to rise. fell, resulting in an improvement in cost performance. Therefore, during the purchase process, if the merchant emphasizes how the price of a certain product is excellent compared to a certain product, and the price-performance ratio is extremely high, you should be careful. Maybe this big pie is a big trap for you; also, When the product price changes, you should not only pay attention to the change in product price, but also pay attention to the change in product performance (overall quality, number of accessories, etc.). Specifically, when you find a price change, you must find out why the change occurs and the main reasons for the change. Where, whether it is due to process improvement, promotion, clearance or other reasons, don't let the price/performance ratio confuse you.
