Now it’s the same with the processor in the iPhone 7. The reason why the performance of the dual core processor in the iPhone 6 is better than most quad core and octa core Android phones of that time is because the processor chip in was the best mobile chip in the world at that time. Here, the amount of water you can carry at once is analogous to the average number of instructions executed per clock cycle. Another stupid but simple analogy is, if you need to transfer the water from one water tank to another water tank using buckets, how much water can you carry at once and how much water a pro body builder can carry at once. Simply stated IPC is “the average number of instructions executed for each clock cycle”. ![]() ![]() Some overlooked but more important aspect are memory bandwidth and ability to execute threads in a more efficient way. For example, here’s the benchmark result of iPhone 6 with Samsung note 4 and HTC desire 820.ĭigging deeper we can find that the performance depends more on other factors than just core count and speed (frequency) of a processor chip. A simple and rather stupid but easy to understand analogy here, can two bodybuilders lift more or two skinny guys? It’s more or less the same thing. Simply speaking it’s not the core count that matters, but how much work can a single core do. ![]() So what defines the performance of a device is not core count? Hectare to Acre Conversion Table Hectare ġ5 ha = 15 × 2.4710538147 ac = 37.From the above statements we can conclude that it’s not the core count that matter, or else Apple iPhones would not be near any the performance of any Android phones much less outperform them. However, area measurements are typically not accurate enough for the difference between the two acre measurements to be detectable. The United States (US) uses both international as well as US survey acres (~4047 square meters), which vary based on which type of yard is used in the measurement. The most commonly used acre today, the international acre, is based on the international yard, which was defined in 1959.Ĭurrent use: Acres are used in countries including the United States, the UK, Ghana, India, Canada, and others. Before the metric system was adopted, many countries used their own versions of the acre. History/origin: In the Middle Ages, the acre was defined as the area that a yoke (pair) of oxen could typically plow within one day, using a wooden plow. ![]() It is defined as the area of 1 chain (66 feet) by 1 furlong (660 feet), which is exactly equal to 1/640 of a square mile, 43,560 square feet, or exactly 4046.8564224 square meters. Even though it is not an SI unit (just a unit accepted for use with SI) the SI brochure states that the use of the hectare is expected to "continue indefinitely." Acreĭefinition: An acre (symbol: ac) is a unit of land area used in the imperial and US customary systems. The "are" is still used in certain areas when referencing real estate, particularly in India, Indonesia, and a number of European countries.Ĭurrent use: Hectares are primarily used to measure land area around the world. The term hectare is derived from the metric prefix "hecto," denoting a factor of one hundred, and the metric area "are," a metric unit for measuring area that has fallen out of use in SI. History/Origin: The hectare was first introduced in 1795 as part of the metric system. One hectare is equal to 10,000 square meters and is equivalent to approximately 2.471 acres. It is primarily used to measure land area. Definition: A hectare (symbol: ha) is a unit of area that is accepted in the International System of Units (SI).
