Intel Core 2 Duo E6300 Bulk VS Intel Core 2 Duo E4500 Box

1.Main frequency: The main frequency is also called clock frequency, the unit is MHz, which is used to indicate the computing speed of the CPU.

The main frequency is determined by the external frequency and the frequency doubling, and its calculation formula is the main frequency of the external frequency * frequency doubling. The external frequency is the working frequency of the system bus; The frequency doubling refers to the multiple of the difference between the CPU external frequency and the main frequency. For example, if the external frequency of the Intel Pentium4 processor is 133 and the frequency is 23, the main frequency is 133*23

2.External frequency: The external frequency is the base frequency of the CPU, and the unit is also MHz.

The external frequency is the speed of synchronous operation between the CPU and the motherboard, and in most of the current computer systems, the external frequency is also the speed of synchronous operation between the memory and the motherboard.

3.FSB: The FSB frequency directly affects the speed at which the CPU can exchange direct data with memory.

Since the maximum bandwidth of data transmission depends on the width and frequency of all simultaneously transmitted data, i.e. the amount of data transferred (bus frequency * data bandwidth) 8. The difference between the frequency of the external frequency and the front-side bus: The speed of the front-side bus refers to the speed of data transmission, and the external frequency refers to the speed of synchronous operation between the CPU and the motherboard.

For example, 100MHz external frequency refers to the digital pulse signal at **10 million times per second, while the 100MHz front-side bus means that the acceptable data transfer amount of the CPU per second is 100MHz*64bit (8byte bit) 800MB s.

4.Frequency doubling coefficient: The frequency doubling coefficient refers to the relative proportional relationship between the CPU main frequency and the external frequency.

At the same external frequency, the higher the doubling, the higher the frequency of the CPU. But in fact, under the premise of the same external frequency, the CPU itself with high frequency doubling is not of great significance. This is because the data transmission speed between the CPU and the system is limited, and the CPU that blindly pursues high frequency doubling and obtains a high main frequency will have an obvious "bottleneck" effect - the ultimate speed of the CPU to get data from the system cannot meet the speed of CPU operation.

5.Memory bus speed: The CPU processes data from memory, and the main memory is memory.

Generally, the data placed on the external memory (disk or various storage media) must pass through the memory and then enter the CPU for processing. Therefore, the memory bus speed of the channel between the CPU and the memory is very important for the overall system performance. Since there is a greater or lesser difference in the speed of operation between the memory and the CPU, there is a L2 cache to coordinate the difference between the two, and the memory bus speed is the communication speed between the CPU and the L2 cache and memory.

6.Expansion bus speed: Expansion bus refers to the local bus installed on the computer system such as VESA or PCI bus, when we turn on the computer, we will see some slot-like things, these are expansion slots, and the expansion bus is the bridge between the CPU and these external devices.

After reading this, which one do you think is better?

It must be E6300 strong, but there may be fakes in bulk, and the ones that come directly with fans in boxes are **.

The Pentium dual-core E6300 is much stronger than the Core dual-core E6300.

The Pentium dual-core E6300 is a Wolfdale architecture, while the Core dual-core Conroe architecture. The Wolfdale is 45 nm and the Conroe architecture is 65 nm. The Besturn dual-core E6300 is more precise, with the same volume, integrating more transistors (computing units), and the computing efficiency is of course stronger.

In addition to that, the Pentium Dual-Core E6300 is, while the Core Dual-Core E6300 only. As the main frequency that dominates the computing speed, the Besturn dual-core is a lot higher, and the performance is obviously much stronger.

Although the Pentium dual-core is "named Pentium", it is actually an upgraded version of the front-end bus of the Pentium dual-core E5300, and the second-level cache version of the Core dual-core E7400 is two-thirds of the version, and the performance is stronger than all the Pentium and Core versions below the E7300 number. Although the Pentium dual-core E6300 is positioned as a low-end user, while the Core dual-core E6300 is a mid-to-high-end user, the Pentium dual-core E6300 was just released in 2009, while the Core dual-core was in 2006. The times are different, and the requirements for end-bit performance are also different.

At that time, some server processors Xeon may not be comparable to the current low-end processors in the family E5300, not to mention the Core dual-core E6300 vs. Pentium dual-core E6300.
