P series is a newly released Centrino 2 processor (P8600, P8400), but T series also has Centrino 2 platform. (T9600, T9400) On the whole, P series is superior to T series in performance, with more advanced technology and lower power consumption. However, Centrino's second-generation notebook has just been listed, and the price is relatively high. T series is generally enough, with better power consumption and heat control and higher cost performance. T and P are different from TDP. The thermal design power consumption of SP U series is lower than that of T, and T is 35W U. P is 25U. See what Intel says: T: mobile high performance-focusing on high performance P: optimizing energy efficiency, higher performance-focusing on high performance SP: optimizing energy consumption, SSF- focusing on energy saving LV: low voltage-low voltage version ULV: ultra-low voltage version QX: quad-core extreme- The main difference is that under the condition of the same frequency and the same price, the energy saving effect of P series is better and the performance of T series is better. The main difference between P series and T series lies in the different thermal power consumption. The P series is 25W, which is better than the T series' 35W. At present, the commonly used P-series CPUs are P7350, P8400, P8600 and P9500P9500, which are obviously higher than T7 and T8, while P8400, P8600 and the middle and low-end CPUs of T7 and T8 (such as T7300, T7500, T8 100) have certain advantages, but because of the secondary level, P processor is a new generation of Centrino 2 low-power processor released by Intel on July 15, 2008. The power consumption is reduced to 25W, but the performance is improved by 30% compared with that of T processor, and the graphics performance is improved by 10% ~. T starts with Centrino 1 generation U (except T9XXX), and P starts with real fast 2. T series refers to the notebook cpu with cpu power consumption of 35w. Before T2370, T-series CPU was 90nm, T2370 to T7 series were 65nm, and T8 and T9 series were 45nm. P series refers to the notebook cpu with cpu power consumption of 25w. P series starts from P7250, and all are 45nm processes. P-series cpu is released together with Centrino 2 platform, and its main feature is to reduce the power consumption of 10w, which makes the cpu generate less heat, work stably and last longer, but correspondingly, compared with T-series cpu with the same main frequency, its computing power is rarely reduced. There is no difference between the two series, Centrino 2 notebook and two series of cpu. T series emphasizes computing power, and P series emphasizes low power consumption. Therefore, general business will choose P series, and entertainment will choose T series. The TDP of p is 25WT. The TDP of p is 35WT. This series has Centrino 4.5 and 5 (Intel must call Fast 2. No way). P series are all Centrino 5 (Fast 2). Buy P series if you have enough money! This is the manufacturing process of two generations. One is 65NM, and the other is 45NM, which directly leads to differences in calorific value, battery life and other indicators. Of course, the front-end bus memory specifications, wireless network cards and other parameters are different. P series is not very expensive now. I suggest buying P. In terms of shopping, I am generally entangled and like to ask for trouble. Recently, I am thinking about opening a laptop, and my head is getting bigger and bigger. After surfing the Internet for a few days, I gained a lot of knowledge (you can never judge the performance of cpu simply by the number after T). In the face of such a dazzling array of dual-core cpu and such a rapid update of inter, I found a clue and shared it with you below. Please correct me if there is anything wrong. 1. Purchase principle: purchase on demand. Anyone who buys a cpu according to his own needs should know the main purpose of buying a computer. At present, the needs of the vast majority of users have not changed much from three or five years ago-downloading movies online, listening to music, working, playing some games such as qq and cs. At present, the performance of Celeron dual-core T 1600 is basically enough, while the Pentium dual-core T4200 with 45nm can fully meet the needs of most users. In other words, as far as the T-series processors are concerned, the models above Core 2 T6400 have excessive performance, so there is really no need to spend thousands of dollars more. If you are a gamer and want to keep pace with the times in large-scale games, then match the discrete graphics card with a slightly higher-end cpu to give full play to the performance of the discrete graphics card. There are many main indicators of 2.cpu performance, but we don't have to consider them one by one, otherwise you will be more worried than me. The main performance indicators are as follows: architecture (process) >; Main frequency > secondary cache > front-end bus >: I won't elaborate on the specific definitions and functions of these indicators in the process. Those who want to struggle can learn from themselves and expand their knowledge. My understanding is that architecture is the focus of consideration, because it symbolizes better production technology and higher scientific and technological content. Just like basketball shoes with the slogan of shock absorption, I personally think Adidas and Nike are not in the same class. Because of the different internal structure, Adidas' shock absorption technology can't catch up with Nike's zoom air cushion at present. If you want to buy a high-performance cpu, then the architecture should be your first consideration. However, the judgment of the architecture cannot be simply determined by the number after T. Unlike Core T5 series, Pentium T3 series and even Pentium T2 series, they are all merom architectures, and the latest T4, T6 and T8 are all penryn architectures. See the picture below published by zol for details. If the architecture is the same, then the main frequency is the focus of your consideration, which almost directly determines the running degree of cpu. When running a single task, the higher the main frequency, the faster the speed. If, like me, you like to run multiple tasks at the same time, such as opening N web pages while opening thunder here, then secondary caching is what you should consider. Process means power consumption, and power consumption means heat dissipation, which means the efficiency of cpu work and the life of battery. All of the above are based on one variable. But what if it is multiple variables? What about T3400 and T5800 or even T3400 and T6400? This is more complicated, but basically the indicators can be complementary. Now, after many tests, many players show that if the cpu is not running at full capacity, the gap between the two is not big, and the performance gap between the high-end Pentium dual-core and the low-end Core dual-core is 5- 10 percentage point. If your laptop is not flat (it's obviously not my style to open n programs at the same time) and the system is clean, it's almost negligible.
