Processor Series Model

According to the market positioning of CPU products, CPU manufacturers determine a series of models that belong to the same series of products to facilitate classification and management. In general, the series models can be said to be important identifiers for distinguishing CPU performance.

The early CPU series models did not have a clear distinction between high and low end, such as Intel's Pentium and Pentium MMX for the mainstream desktop market and the Pentium PRO for high-end server production; AMD's K5, K6, K6-2 for the mainstream desktop market. And K6-III and K6-2+ and K6-III+ for the mobile market and so on.

With the development of CPU technology and IT market, Intel and AMD, two major CPU manufacturers for the purpose of market segmentation, invariably subdivide their own CPU products into high and low end, so as to segment the market by the level of performance. . The difference between high- and low-end CPU series models is nothing more than the secondary cache capacity (usually only a quarter of the high-end products), FSB, front-side bus frequency, supported instruction set, and support for special technologies. Importantly, basically, low-end CPU products are considered to be a shrinking version of high-end CPU products. For example, Intel's Celeron series has only a 128KB L2 cache and a 66MHz and 100MHz FSB in addition to the original product without a second-level cache, which is much lower than the Pentium II/III/4 series of its current generation. While AMD's Duron still has only 64KB of L2 cache, the FSB is always an order of magnitude lower than its current generation of Athlon and Athlon XP.

After the CPU series was divided into high and low end, the two major CPU manufacturers respectively launched their own series of products. In terms of desktop platforms, there are Intel Pentium II, Pentium III, and Pentium 4 for the mainstream desktop market, and the Celeron series (including the I/II/III/IV generation) for the low-end desktop market; and AMD faces the mainstream. Desktop markets Athlon, Athlon XP, Duron and Sempron for the low-end desktop market, and more. In terms of mobile platforms, Intel has mobile Pentium II, Mobile Pentium III, Mobile Pentium 4-M, Mobile Pentium 4 and Pentium M for high-end mobile markets and Mobile Celeron and Celeron M for low-end mobile markets; AMD is also facing Mobile Athlon 4, Mobile Athlon XP-M and Mobile Athlon 64 in the high-end mobile market, and Mobile Duron and Mobile Sempron for the low-end mobile market.

At present, the series models of the CPU are further subdivided into three types: high school, low school, and high school. In the case of desktop CPUs, for Intel, the high-end is the dual-core Pentium EE and the single-core Pentium 4 EE, the midrange is the dual-core Pentium D and the single-core Pentium 4, and the low-end is the Celeron D. Celeron has been eliminated (commonly known as Celeron IV); and AMD, the high-end Athlon 64 FX (including single-core and dual-core), the middle is the dual-core Athlon 64 X2 and single-core Athlon 64, At the low end is Sempron. For notebook CPUs, the Intel high-end is the Core Duo, the mid-range is the Core Solo and the Pentium M is about to be eliminated, and the low-end is the Celeron M; and for the AMD, the high-end is the Turion 64. The mobile Athlon 64 is in the middle, and the Mobile Sempron is in the low.

However, when buying a CPU product, it is important to note that the level of CPU performance is differentiated by the serial model only for the same period of time. Everything is relative, and today's high end is tomorrow's mid-end and acquired low-end. For example, the old high-end Pentium 4 and Pentium M have now been reduced to mid-range products, and AMD's Turion 64 will be reduced to mid-range products after the Turion 64 X2 is released. In addition, some series models have a very large time span. For example, Intel's Pentium 4 series has been in existence for six years since its release in November 2000. At that time, the high-end Pentium 4 was far behind its performance. Celeron D. And low-end CPU products have also appeared in many overclocking performance known or can modify the fine, such as Intel's early Celeron 300A, the middle of the Latin core of the Celeron III series, and now the Celeron D series, etc. And so on; AMD also has early Duron because it can rely on connecting Golden Bridge and modified to Athlon and Athlon XP is popular, the mid-term Barton core Athlon XP 2500 + and now 64-bit Sempron 2500 + are known for overclocking performance. The performance of these low-end products after modification and overclocking is not worse than that of the mainstream high-end models in the same period, and the price/performance ratio is very high.
