RX 470D Advantages: Video memory bit wide, stronger performance;
GTX1050 TI Advantage: The core frequency is high, the power consumption is low, the price is cheap 100 yuan.

frequency of the linked table lookup, Binary lookup tree and AVL tree lookup. In Figure 3.4, some of the numbers are negative because the length value of the lookup exceeds the maximum numeric representation range of type int in C, resulting in an overflow.In Figure 3.5, there is a time-consuming comparison of four algorithms, which is generated by importing the experimental data from above into MATLAB. We can intuitively see the four algorithms, the

This article illustrates the comparison and analysis of file_get_contents and curl performance in PHP. Share to everyone for your reference. Specifically as follows:
In PHP if not careful to analyze performance will find that file_get_contents and curl two have a lot in common, they can collect file open file, but if a careful
uses Redis storage, performance is better than tair, and support data grouping, can be based on the product ID and user ID data merge.disadvantage: the same should be developed based on a C module Nginx module, later maintenance also need a little trouble.Tair LDB and Redis's pair test

Three serialization methods, json_encode, serialize, and igbinary, have been tested before. PHP5.5 has not been tested yet. This test is based on PHP5.5 and is a test case,Http://blog.csdn.net/hguisu/article/details/7651730The test cases are the same, but from this test home igbinary serialize test, as a

found through the Code test, the performance of try catch in a loop is higher than that in a loop, while I always thought that try catch outside the loop is better than that in a loop. In addition, JDK tests of different versions show that JDK 7 is better than JDK 6, but if try catch is not used, JDK 6 performs a little better than JDK 7. We hope to discuss this with you. The following is my test code. JDK 1.6.0 _ 34 x64 and JDK 1.7.0 _ 09 x64 ar

After reading the test results of the PCMark05 software, we will compare the performance of the Vista operating system and Windows XP operating system on the three main components of the video card, processor, and hard disk. For laptops with independent graphics cards, we fully tested their display performance. For Fujitsu P7230 with integrated graphics cards, we only tested 3DMark03.
