Price–performance ratio

In economics and engineering, the price/performance ratio refers to a product's ability to deliver performance, of any sort, for its price. Generally speaking, products with a lower price/performance ratio are more desirable, excluding other factors.

Price–performance is often written as cost–performance or cost–benefit. 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.

Examples

Consumer and medical products

According to futurist Raymond Kurzweil, products start out as highly ineffective and highly expensive.

Gradually, products become more effective and cheaper until they are highly effective and almost free to buy. Some of the products that have followed this example include AIDS medications (which are now affordable to the majority of AIDS sufferers), text-to-speech programs, and digital cameras. However, products that rely primarily on paper (e.g., newspapers and toilet paper) and/or fossil fuels (e.g., electricity in most countries and petroleum gasoline for automobiles) have only increased in price.

Computer performance

Computer performance is characterized by the amount of useful work accomplished by a computer system or computer network compared to the time and resources used. Depending on the context, high computer performance may involve one or more of the following:

Technical and non-technical definitions

The performance of any computer system can be evaluated in measurable, technical terms, using one or more of the metrics listed above. This way the performance can be

Whilst the above definition relates to a scientific, technical approach, the following definition given by Arnold Allen would be useful for a non-technical audience:

Performance (film)

Performance is a 1970 British crime drama film directed by Donald Cammell and Nicolas Roeg, written by Cammell and starring James Fox and Mick Jagger of The Rolling Stones, in his film acting debut. The film was produced in 1968 but not released until 1970.

Plot

Chas (James Fox) is a member of an East London gang led by Harry Flowers (Johnny Shannon); his specialty is intimidation through violence as he collects pay-offs for Flowers. He is very good at his job, and has a reputation for liking it. His sexual liaisons are casual and rough. When Flowers decides to take over a betting shop, owned by Joey Maddocks (Anthony Valentine), he forbids Chas to get involved, as he feels Chas's complicated personal history with Maddocks (which is at least partly gay) may lead to trouble. Chas is angry about this and later humiliates Maddocks, who retaliates by wrecking Chas's apartment and attacking Chas. Chas shoots him, packs a suitcase and runs from the scene.

When Flowers makes it clear that he has no intention of offering protection to Chas but instead wants him eliminated, Chas decides to head for the countryside to hide but instead winds up hiding out in London, requesting that Tony (a trusted friend he refers to as 'Uncle') helps him get out of the country. He assumes a new name, Johnny Dean, and appears at the house of Turner (Mick Jagger), makes a clumsy attempt to ingratiate himself with Pherber (Anita Pallenberg), one of the female inhabitants, and moves in. Turner is a reclusive, eccentric former rock star who has "lost his demon", and who lives there with his female friends Pherber and Lucy (Michele Breton), with whom he enjoys a non-possessive and bisexual ménage à trois, and their child maid Lorraine (Laraine Wickens).

Price

In ordinary usage, price is the quantity of payment or compensation given by one party to another in return for goods or services.

In modern economies, prices are generally expressed in units of some form of currency. (For commodities, they are expressed as currency per unit weight of the commodity, e.g. euros per kilogram.) Although prices could be quoted as quantities of other goods or services this sort of barter exchange is rarely seen. Prices are sometimes quoted in terms of vouchers such as trading stamps and air miles. In some circumstances, cigarettes have been used as currency, for example in prisons, in times of hyperinflation, and in some places during World War 2. In a black market economy, barter is also relatively common.

In many financial transactions, it is customary to quote prices in other ways. The most obvious example is in pricing a loan, when the cost will be expressed as the percentage rate of interest. The total amount of interest payable depends upon credit risk, the loan amount and the period of the loan. Other examples can be found in pricing financial derivatives and other financial assets. For instance the price of inflation-linked government securities in several countries is quoted as the actual price divided by a factor representing inflation since the security was issued.

Price (surname)

Price is a patronymic name derived from the Welsh "ap Rhys" meaning "son of Rhys". The given name Rhys means "enthusiasm" in Welsh. It is a common surname among those of Welsh ancestry. At the time of the British Census of 1881, its frequency was highest in Radnorshire (38.2 times the British average), followed by Brecknockshire, Herefordshire, Monmouthshire, Flintshire, Shropshire, Denbighshire, Glamorgan, Carmarthenshire and Worcestershire. The surname has many other spellings including Priess, Priesz, and many others.

The name is thought to have originally been spelled "Pryce" and pronounced "Preese". Name experts believe that the change of the "y" to "i" and the subsequent change in pronunciation was originally an affectation meant to make the name seem more English and therefore more prestigious.
