优质性价比 excellent price-performance ratio
From Wikipedia, the free encyclopedia：
Price/performance is often written as price-performance. Even though this term would seem to be a straightforward ratio, when price performance is improved, better, or increased, it actually refers to the performance divided by the price, in other words exactly the opposite ratio to rank a product as having an increased Price/performance.
