If it is P9 and T9 series. Most P9 is better than T9. But the top end is T9.

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 2 generation notebook has just entered the market, and the price is relatively high. T series is generally enough, and the cost performance is relatively high.
P has better power consumption and heating control.
T and p are the difference of TDP.
There is also SP U series, and the thermal design power consumption of P is lower than that of T.
T is 35W U and p is 25W U.
See what Intel says.
T: mobile high performance-focus on high performance
P: Power optimization, energy efficiency and higher performance-focus on high efficiency.
Sp: Power Optimization Performance SSF- Focus on Energy Saving
Low pressure: low pressure-low pressure version
Ulv: ultra-low voltage-ultra-low voltage version
Qx: Quad-Core Extreme-Quad-Core Extreme Performance
X: Extreme-Extreme Performance
The biggest difference between t and p is TDP…… ... ...
Performance depends on the specific model!
The main gap is the price.
At the same frequency, P series has better energy saving effect and T series has better performance.
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 P9500.
P9500 is significantly higher than T7 and T8 in all aspects.
P8400 and P8600 have some advantages over the low-end CPU of T7 and T8 (such as T8300, T7500, T8 100), but because the secondary cache is only 3M, it is difficult to say that the CPU with higher primary frequency is almost the same as the secondary cache.
T series processor is the mainstream processor model at present, but its calorific value is relatively high, reaching 35W, but it is also the mainstream processor at present.
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 T9XXX).
The beginning of p is really fast.
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 25W.
The TDP of t is 35W.
T series has Centrino 4.5 and 5 (I can't help it if it is 5 (Intel insists on calling it Fast 2).
P series are all Centrino 5 (Fast 2).
If you have enough money, buy P series!
This is the manufacturing process of two generations.
One is 65 nanometers and the other is 45 nanometers.
Directly lead 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.
When it comes to shopping, I'm usually obsessed and like asking 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.
2.2. Main indicators of CPU performance
There are many indicators, but we don't have to consider them one by one, otherwise you will be more troubled than me.
The main performance indicators are as follows: architecture (process) >; Main frequency > secondary cache > front-end bus >: processing procedure
I won't elaborate on the specific definitions and functions of these indicators. 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 many players have been tested many times, and it shows that if the cpu is not running at full capacity, there is not much difference between the two. 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. Here are a few articles I collected and compared with cpu testing for your reference:
1) Evaluate 45nm Penryn and 65nm Merom.
2)45nm is in power! Launch five new processor laptops
3) Evaluation 3)T3400 and T6400
4) authoritative and comprehensive cpu performance rankings abroad.
5) Comprehensively analyze the models of mobile CPU and graphics card.
