7. Core 2 Duo
The Core 2 Duo series adopts a new naming rule, which consists of a prefix letter plus four digits, in the form of Core 2 Duo letter + xxxx, for example Core 2 Duo E6600 and so on.
The prefix letter in the number represents the range of the processor TDP (thermal design power consumption). Currently, there are four types: E, T, L and U. "E" means that the TDP of the processor will exceed 50W, mainly for desktop processors; "T" means that the TDP of the processor will be between 25W-49W, and most mainstream mobile processors are T series; "L" It means that the TDP of the processor is between 15W and 24W, which is the low-voltage version; "U" means that the TDP of the processor is lower than 14W, which is the ultra-low voltage version. The products that have been released so far are only E series and T series, and L series and U series will be added around the end of 2006.
Among the four digits after the prefix letters, the first digit from the left represents the product series, and odd numbers are used to represent mobile processors, such as 5 and 7, etc., in the case of the same prefix letters The larger the number below, the higher the specifications of the product series. For example, the specifications of the T7x00 series are higher than the T5x00 series. Use even numbers to represent desktop processors, such as 4, 6, 8, etc. If the prefix letters are the same, the numbers The larger the number, the higher the specifications of the product series. For example, the specifications of the E6x00 series are higher than those of the E4x00 series. The following three digits indicate the specific product model. The larger the number, the higher the specifications. For example, the E6700 specifications are higher than the E6600, and the T7600 specifications are also higher than the T7400.
8. Core 2 Extreme
The Core 2 Extreme series also adopts a naming rule similar to the Core 2 Duo, which still consists of a prefix letter plus four digits, such as Core 2 Extreme X6800 and so on.
Currently, there is only one prefix letter "X", but unlike the Core 2 Duo series, the prefix letter in the number does not represent the range of the processor TDP (thermal design power consumption), "X" The meaning is "Extreme", which means extremely fast and top-notch, indicating that this is the top-notch PC processor.
Among the four digits after the prefix letter, the first digit from the left still represents the product series. When the prefix letters are the same, the larger the number, the higher the specification of the product series. Currently, there is only one 6 series. At the end of 2006 An 8 series will also be added, the front side bus will be increased to 1333MHz FSB and a quad-core design will be adopted. The following three digits indicate the specific product model. The larger the number, the higher the specification.

All Mobile Pentium 4-M series are directly marked with frequency, such as Mobile Pentium 4-M 2.0GHz, etc. The higher the frequency, the higher the frequency. Indicates the higher the specification.
3. Mobile Pentium 4
All Northwood core products in the Mobile Pentium 4 series are directly labeled with frequencies, such as Mobile Pentium 4 2.66GHz, etc. The higher the frequency, the higher the specification. The higher the number, only some models in this series support hyper-threading technology; while all Prescott core products are marked with three digits, in the form of Mobile Pentium 4 5xx, such as Mobile Pentium 4 538, etc. The larger the model number, the higher the number. Indicates that the higher the specifications, all models in this series support hyper-threading technology.
4. Celeron M
The Celeron M series are all marked with three digits, in the form of Celeron M xxx, and some models will also add a suffix letter (usually J , which represents support for hardware anti-virus technology EDB). Among the three digits of the product number, the first digit is used to distinguish the CPU core, where 3 represents the Banias core or the Dothan core, and 4 represents the Yonah core; the second digit represents the specific product model, and the larger the number, the higher the specifications. , for the Celeron M 3xx series, the second digit also has the function of distinguishing the CPU core. Those below 5 are Banias cores, while those above 5 are Dothan cores; the third digit is used to indicate the core voltage. Among them, 0 represents the normal voltage version, and 3 represents the ultra-low voltage version. For example, Celeron M 360J is the normal voltage version of the Dothan core and supports EDB, Celeron M 333 is the ultra-low voltage version of the Banias core, Celeron M 423 is the ultra-low voltage version of the Yonah core, and so on.
5. Pentium M
Early Pentium M products (all Banias cores) directly use frequency markings, and some products also use letter suffixes, where LV stands for low voltage. version, while ULV stands for ultra-low voltage version, such as Pentium M 1.3GHz LV and so on.
Later Banias core products and all Dothan core products are marked with three digits in the form of Pentium M 7xx. Some models will also be added with a suffix letter (usually J, which represents supported hardware Antivirus technology EDB). In the 3-digit product number, the first digit indicates the processor product series, 7 represents Pentium M; the second digit indicates the specific product model, the larger the number, the higher the specification; the third digit indicates the front-end Bus frequency or core voltage, where 0 represents the normal voltage version of 533MHz FSB, 5 represents the normal voltage version of 400MHz FSB, 8 represents the low-voltage version, and 3 represents the ultra-low voltage version, both the low-voltage version and the ultra-low voltage version 400MHz FSB.
For example, Pentium M 733J is an ultra-low voltage version that supports EDB, Pentium M 738 is a low-voltage version, Pentium M 765 is a normal voltage version of 400MHz FSB, and Pentium M 760 is a normal voltage version of 533MHz FSB.
6. Core Duo and Core Solo
Core Duo and Core Solo also adopt a new naming rule, which consists of a prefix letter plus four digits, in the form of Core Duo letter + xxxx, some models will also use the form of adding a letter suffix after the number (usually E, which means that virtualization technology Intel VT is not supported), such as Core Duo T2300E and so on.
The prefix letter in the number represents the range of the processor TDP (thermal design power consumption). Currently, there are three types: T, L and U. Among them, "T" represents the TDP of the processor between 25W-49W, and most mainstream mobile processors are T series; "L" represents the TDP of the processor between 15W-24W, which is the low-voltage version. ; "U" means the TDP of the processor is lower than 14W, which is the ultra-low voltage version.
Among the four digits after the prefix letter, the first digit from the left represents the product series, and can also indicate the number of cores of the processor, where 1 represents a single-core Core Solo and 2 represents a dual-core Core Duo; the following three digits represent the specific product model. The second digit represents the specific specifications of the product. If the prefix letters are the same, the larger the number, the higher the product specifications; the third digit represents Front-side bus frequency, 0 represents the normal FSB frequency in the series, and 5 represents the FSB frequency one level lower than 0. For example, Core Duo L2400 is a dual-core low-voltage version, while Core Solo T1350 is a single-core normal voltage version and the FSB frequency is one level lower (533MHz FSB) than the ordinary T series (667MHz FSB), etc.
3. Server and workstation platforms
Before 2006, server and workstation platform processors, whether they were Xeon, Xeon MP or Itanium 2, directly used the frequency marking method. The problem is that when processors have different core types, front-side bus frequencies, L2 and L3 cache capacities, supported features, etc., it is impossible to distinguish between different models of processors simply by relying on the marked frequencies. . For example, Xeon 2.0GHz has two core types: Foster and Prestonia. The former is a 0.18um process and a 256KB L2 cache, while the latter is a 0.13um process and a 512KB L2 cache. The Xeon 2.0GHz Prestonia core is also divided into Socket 603 interfaces. The 400MHz FSB version and the 533MHz FSB version of the Socket 604 interface; , and the third-level cache of the Potomac core Xeon MP 3.0GHz is also divided into two versions: 4MB and 8MB. In view of the above disadvantages, Intel learned from the successful experience of using processor numbering on desktop and mobile platforms, and officially began to use processor numbering on server and workstation platforms in 2006.
Server and workstation platforms have four-digit processor numbers. The first number on the left represents the processor family. The larger the number, the higher-end the processor family. Among them, 5 represents Xeon, 7 represents Xeon MP, and 9 represents Itanium 2.
The second digit represents different product series in the same processor family, and can also be used to distinguish different processor cores. The larger the number, the later the series of products are released, more advanced, with higher specifications and higher performance For example, the Xeon 5000 and 5100 series are Dempsy core and Woodcrest core respectively, and the Xeon MP 7000 series and 7100 series are Paxville core and Tulsa core respectively. The latter is released later than the former and has stronger performance. The third digit represents the specific product specification model. The higher the number, the higher the specification. For example, Xeon 5160 is better than Xeon 5150. The main purpose of the fourth digit is to distinguish the front-side bus frequency when the frequency of the same series of products is the same. For example, the Xeon MP 7040 and 7041 have the same frequency of 3.0GHz. The former is 667MHz FSB and the latter is 800MHz FSB; the fourth digit Another use is to mark the low-voltage version. The method is the same as the mobile platform processor number, which is represented by 8 and 3. For example, Xeon 5148 and Xeon 5140, Xeon 5063 and Xeon 5060, except that the core voltage of the former is lower than that of the latter. Other parameters are the same as the latter.
This is INTEL, AMD and VIA also have their own naming rules.
