digits that the CPU can process at a time.
32-bit: The 32-bit computer's CPU can process up to 32-bit data at a time
64-bit: that is, the processor can run 64-bit data at a time.
CPU level (i386, i586, i686, x86_64)
This is widely used in Linux. This is not the case in windows.
The CPU in Intel Pentium MMX and AMD K6 is called i586, while the 32-bit CPU after intel celon and AMD athlon (K7) is called i686. Currently, 64-bit is called x86_64.

Recently, compare the query performance of xpath and JCR-SQL2 in jackrabbit, although JCR no longer recommends the use of xpath from version 2.0, but in terms of the query performance, XPath seems much higher than the JCR-SQL2
The following are the comparison results.

little slower than Delphi's windows IDE. On an athlon 1.2ghz machine equipped with an NVIDIA geforce2 Graphics Accelerator card, it is almost smoke.
At first glance, kylix is like an extraordinary Windows Delphi ide running on Linux. In fact, from context-related help, gorgeous code editor and pop-up syntax wizard menu to drop-down and drag-and-drop Form Designer, every detail of it has been improved. This is not suitable for programmers engaged in c
Disks and soft sound cards may not be supported. Therefore, if another independent frequency generator is used to keep the PCI frequency at 33 MHz without being affected by the CPU outbound frequency, the frequency locking effect will be achieved, in this way, you can enjoy the super frequency with peace of mind. Therefore, a motherboard With insufficient overclocking functions is not suitable for a CPU suitable for overclocking. Let's talk about it now, for example, C4 2.0g, xp1800 +, duron 14

Many people may ask questions about AMD dual-core CPU patching. Here we will provide you with all the patches and setup tutorials.
Thank you, author sunny615.
Users who need dual-core patching: as long as they meet the following requirements, dual-core patching should be applied.
1. Use AMD's dual-core CPU. Including 3600X2, X 2... and so on.
2. Use the Microsoft windows xp operating system.
The following four patches are available:

The CPU architecture is a specification set by the CPU manufacturer for the same series of CPU products. The main purpose is to distinguish different types of CPU. Currently, the CPU on the market is mainly divided into two camps: one is the intel series CPU and the other is the amd series CPU. Two CPUs of different brands have different product architectures. Currently, common intel series CPU products include socket 423, socket 478, and socket 775; amd cpu products have common architectures su
