The main technical features of Pentium III The Intel Pentium p III processor adds 70 instructions-streaming SIMD extension-which significantly enhances the performance required for processing advanced images, 3D, audio streaming, video and speech recognition. The product aims to greatly enhance the Internet experience, allowing users to browse realistic online museums and shops and download high-quality videos. The processor integrates 9.5 million transistors and adopts 0.25 micron technology.
Pentium III Xeon processor Intel Pentium III Xeon processor was produced in 1999.
Intel Pentium III Xeon processor expands Intel's products for workstation and server market, providing additional performance to support e-commerce applications and high-end business computing. This processor integrates 70 SIMD instructions of Intel Pentium III processor, which significantly enhances the performance of multimedia and video streaming applications. The advanced cache technology of Intel Pentium III Xeon processor accelerates the transmission of information from the system bus to the processor and greatly improves the performance. Processors are designed for systems with multiprocessor configurations.
Main technical features of tualatin Pentium P3-S tualatin Pentium P3-S uses 5 12K full-speed L2 cache, and its core voltage version is1.45v.
Tualatin, let's look back on such a period of history, which can make us more aware of tualatin's position: in the genealogy of Pentium III, a * * * has gone through three generations of cores, and the first generation Pentium III of 1999 adopted Katmai core based on 0.25 micron production technology. Compared with the previous Pentium 2, the biggest difference is that it supports the brand-new SSE multimedia instruction set. This earliest Pentium III processor uses 5 12KB external half-speed cache. At the beginning of 2000, due to the introduction of 0. 18 micron production technology, the processor architecture has undergone tremendous changes. The original external second-level cache can be easily integrated into the kernel, and it is a full-speed second-level cache (that is, an 8-way joint mechanism with the same speed as the main frequency of the processor), so the second generation Pentium III and Coppermine Pentium III were born. Two different versions of the front-end bus frequency, 100MHz and 133MHz, are adopted, which are denoted by "e" and "EB" respectively. Although the capacity of the secondary cache is reduced from 5 12K to 256K, the higher working frequency of the secondary cache makes up for the performance loss caused by the reduced capacity of the secondary cache. So who is the terminator in the copper mine? Is the processor of the aforementioned "tualatin" core.
The story about the birth of the beautiful rainbow tualatin is fleeting;
Tualatin is a transitional product from Pentium III to Pentium 4 and a substitute for copper mine. Its birth is very dramatic. Everyone knows that the first desktop processor that broke through 1Ghz in history was introduced by AMD, which made a proud Intel lose face. Coupled with the success of AMD Athlon processor in the market, this is what Intel did not expect. So AMD and Intel started a speed race.
But at this time, Intel was in big trouble. Pentium III, the core of copper mine, has a problem in the key position of crossing 1GHz, and AMD's processor can continue to speed up without changing the architecture. Unwilling to lose to AMD, Intel crustily skin of head launched the Pentium III copper mine of 1. 13GHz, hoping to save its image. However, after the introduction of this CPU, it was found that the Pentium III copper mine of 1. 13GHz was seriously unstable and had huge defects. Results 1. 13GHz Pentium III copper mine was recalled in less than one month after sale, so people called 1. 13GHz Pentium III copper mine "slag". For a long time, Intel kept silent about 1. 13Ghz.
Under such circumstances, Intel Letters hastily launched the first generation Pentium 4 with Willamette core (423-pin socket), while the previous Pentium III-S(370-pin socket) and the Pentium III-S with tualatin core (370-pin socket) also appeared. An unimaginable thing happened, because tualatin adopted a more advanced 0. 13 micron process and a 2-level full-speed cache of 5 12k. In terms of performance and execution efficiency, it far exceeds Willamette Pentium 4 with the older 0. 18 micron process and 256K external L2 cache. In other words, Pentium III-S is better than Pentium 4! This is the last thing Intel wants to see. The painstakingly cultivated Pentium 4 market has actually been threatened by Pentium 3. In addition, Intel once said: "socket370 is the framework to be eliminated", so if the socket370 tualatin introduced by Intel at this time is stronger than the 423-pin Willamette Pentium 4, wouldn't it be a renege? Helpless to give up what one favours, tualatin Pentium III-S turned to the server field and notebook field, and hardly appeared in the retail market. However, Intel will not throw away this excellent kernel in vain, so it put the * * * version of tualatin Pentium III-S- tualatin Celeron (that is, the third generation Celeron) into the market, becoming the killer weapon of Intel's low-end market. A total victory, defeating the dragon of AMD, the leader of the low-end market. Dragon immediately withdrew from the market, and AMD turned to the low-end AthlonXP 1700+ and 65700+.
