The above content is somewhat vague, so what is the performance of the new IVB processor? By testing the results, we can use a simple sentence to summarize: 22nm process of Ivy Bridge architecture processor, its computing power to achieve the I3=I5 (old), i5=i7 (old) completely beyond.
The performance of the cup is almost doubled, and the GPU improvements are obvious, with the mo
forget the imac or an all-in-one machine. The low version 5K Retina imac, priced at $2499 (Mainland China for 17988 Yuan), is equipped with a 3.5GHz Core i5 four processor, 8GB memory, 1TB Fusion drive hard disk and an AMD Radeon R9 m290x video card with a 2GB memory. In the Geekbench and Xbench test, the 5K Retina imac has a slight increase in performance over the older 27-inch imac with the 3.2GHz Core i5
future installed or select a computer friend, It is recommended that the computer with six generation CPU and DDR4 be preferred to get a better experience and not be eliminated easily.
Intel six Generation CPU What do you have? Here is a brief list:
Six generation Pentium series getting started processor recommended: Pentium G4400, Pentium G4500, etc.
Six Daicouri series mainstream processor recommended: i3 6100, i3 6300, i3 6320;
Six Daicouri series of high-end processors recommended:
With the advent of summer vacation, notebook computers will also usher in a peak sales, especially the students will enter the University of friends, are looking for a low-cost but also has a mainstream configuration and performance of students. Lenovo's recently launched IdeaPad U310 Touch seems like a good choice, with a MacBook-like metal fuselage design, with a touchscreen and Windows 8 system, and a good keyboard feel to the needs of students ' friends. So, this is the price of 549 dollars
We know that there are already several kinds of graphics cards, for example, independent graphics, core graphics, as well as integrated graphics, different graphics card positioning is different, a lot of friends for the core graphics, motherboard integrated graphics and independent graphics lack of knowledge, do not know what the difference between the three, the following article in the rookie friend for a brief summary, Hope to help you.
The difference between a core video card and a standal
In today's notebook market, the number of notebook models over 15.4 inches can be counted with two fingers. A large proportion of these products come from Hu Hongyu, and Aspire E5-771g-51t2 is one of the most interesting.
Acer's 17-inch notebook is equipped with the Intel Core I5-4120U processor, 8GB memory, Nvidia gtx840m Independent graphics, 1080p resolution. The official retail price for this device is 799 dollars, but the actual cost
One, using the SUMIF () formula of a single condition sum:
To count the data in column C, the statistical condition is that the data in column B is "conditional one". And put the results in cell C6, we just enter the formula in the C6 cell =sumif (B2:B5, condition one, c2:c5) to complete this statistic.
Two, sum () function +if () function nested way double conditional sum:
If the statistical production of the production of a class of quality of "qualified" product totals, and put the results

ATIV Q is a recent hybrid design by Samsung, from product design, configuration to function to give people a bright feeling. First, it has a unique reversible screen and ultra-thin fuselage, while the 13.3-inch screen also boasts stunning 3200*1800 resolution, with the latest Intel Haswell in the processor and the ability to run Windows 8.1 and Android simultaneously. These stunning features are tucked into a lightweight, slide-in body that is undoubtedly the most unique hybrid design computer o
after the release of Apple hardware we have to look at the Hong Kong Apple's website price, generally there are surprises, but this time by the renminbi exchange rate impact and Apple pricing strategy adjustment, Hong Kong Hong Kong MacBook Pro also has no obvious price advantage. In the new MacBook Pro price, the Hong Kong official website and the domestic official website specifications model Price almost the same. Make a comparison as follows:

Each thread has two instructions, 0-0 represents the first instruction of the first thread, 0-1 represents the second instruction o
Today I see some differences between integer and Int. Here I will record the following:
Int Is the Basic Data Type and directly stores data. integer is a packaging class and an object. It points to this object with a reference.
In Java, packaging classes are mostly used for conversion of various data types.
For example, when you need to put something in arraylist and hashmap, the built-in types such as int and double cannot be put, because the containers are all loaded with objects, which
the unique unit method, the unique remainder distinct method is used to determine the number of cells that can be filled in. The unique unit method is used to determine the number of cells that can be filled in. In addition, the unique unit method is easy to understand.
Compared with the candidate number method, the unique remainder equals the explicit uniqueness method. Although the explicit uniqueness method is the simplest and easiest method to use in the Candidate number method, it is the o
