for INTEL Core Duo I want to know ... ... friends Qi Q

How to buy this? - In fact, this is a very large problems, especially some very unique market situation in China, for sale to consumers is definitely a big problem - from the QQ group and forum and look at all the exchanges, the dual core INTEL processor to understand the most vague, in the face of so many old and new dual-core CPU, how do we choose? Shanghai station we launched posts NB literacy series, took the first commercially available 18-INTEL dual-core CPU all out, give you the most comprehensive solution and analysis:
for INTEL Core Duo I want to know ... ... friends Qi Q: Core Duo mobile processors, including what CPU? [I have to ask]
A: First, the Core Duo is divided into one-and two generations, that is, Yonah (32 bit) and Merom (64 bit) Core ...

Duo mobile CPU
There are many users access to books just for the concept of dual-core is not clear - in the end Core Duo mobile processor "family tree" is like? - Here we put aside the specific parameters and the core, which for the entry-level consumers did not understand the meaning. We mainstream dual-core mobile processor INTEL list of shots for everyone, I believe you will be on the Core Duo has intuitive understanding of the family. Core 1 on behalf of the dual-core (Yonah core)
generation dual-core Core 2 Duo (Merom core)
so far all of the mobile Core Duo processor, which in the above list: the one Yonah core is Core 1 generation (32) - T2400 to the T2700 has been basically out of the market; Merom core Core 2 generation (64) - all current models are in the market. Both in the current INTEL 945 chipset gap of about 20% (MEROM strong performance), and Merom 64-bit technology. About 2 cache, front side bus, virtualization technology, frequency and other parameters of the analysis, we will be in the next few pages to find out more.
Comments: From the list above, we see the emergence of several new dual-core (T2060 T2080 T2350 T5300) is actually caused the greatest distress to the people, the face of cheap, new CPU, the performance choice, we how to choose? We see the following description.


NO.2 new dual-core performance? How to buy?
for the new dual-core I would like to know ... ... friends Qi Q: T2060 T2080 T2350 T5300 dual-core I can buy the new Why? [I have to ask]
A: The new dual-core has a fairly high cost, the price advantage and decent performance, worthy of selection.

INTEL Pentium Dual Core - T2060 dual-core processor
many friends will ask the new T2060 T2080 T2350 T5300 processor performance, they are only appeared in 2007, and INTEL official did not appear in the list of processors, we start to sort out the situation about the new dual-core: INTEL mobile dual-core processor - 8 new dual-core T2060 and T2080
we divided class (front side bus 533, secondary cache 1M), T2250 and T2350 as a class (front side bus 533, secondary cache 2M), T2300E is rather special, you can discuss it and T2300; the T5300 and T5200 are all Core 2 Duo, compared with the two: double check the same point than the market to buy the proposed low-cost dual-core T2060 T2080 CPU 5000-7500 yuan
the typical FSB 533 Cache 1M
worth two options, cost-effective in high-end T2250 T2350 CPU 6000-8000 yuan
the typical front side bus 533 cache 2M
2 Duo dual-core 1 on behalf of the most recommended stocks more than 7500 yuan T2300E T2300 Front Side Bus 667 or so
2 cache 2M
E-free virtualization technology does not affect the use of low-cost T5200 T5300 Core 2 Duo CPU 7000 of the typical element - 9500 yuan
FSB 533 entry-level two cache 2M
Core 2 Duo, cost-effective compared to see from the above list, INTEL cover the new dual-core Core Duo two generations, and in 5000 to 10,000 yuan a comprehensive coverage of prices, which squeeze the space for AMD very small. Haier A61 (T2060 dual-core) and 4800 yuan to 9500 yuan ASUS A8H53Fm, has been fully deployed INTEL Dual-Core. In accordance with the description of the table, the market is the most mainstream dual-core T2060 T2080 T2250 T2350 T5200 T5300, from left to right and gradually improve the performance.
LG R400 - T5300 T2080 dual-core exposure
Comments: several of the hottest new dual-core comparison and market conditions have been analyzed for everyone, and we hope to buy help. Here take a look at the specific parameters and performance analysis, mainly related to: 2 cache, front side bus, virtualization technology, frequency, etc. This is just the most contact with friends from doubts books content.

NO.3 2 cache, front side bus, virtualization technology, clocked at how to think?
for all CPU parameters I want to know ... ... friends Qi Q: CPU frequency is everything? Cache and bus on the performance? [I have to ask]
A: CPU overall performance and frequency is related to directly determine the frequency, but not help.

Core (below) and Core 2 (on) the performance comparison
First of all, frequency is not everything - from the above Core / Core 2 Duo comparison see, with the frequency of dual-core CPU, cache and architecture as two different conditions, will be very obvious impact on performance. In other words, the structure and other conditions being equal, the performance of high frequency high; in frequency only under the same circumstances (for Core and Core 2 Duo), a large high-performance cache. Core Duo ----------------------------- large horizontal comparison of different
again, to analyze 2 cache problem - same Core Duo, or the same Core 2 Duo, in the framework of the same circumstances, 4M and 2M secondary cache contrast, the former performance of the powerful are many; and emerging T2080 and T2060, with than the T2250 and T2050, while the secondary cache reduced from 2M to 1M, but the step so as to improve the structure and,be adjourned to the front" ... ..., at this time of the secondary cache becomes very small. That is, the secondary cache for INTEL dual core, the higher the performance is, but also by the structure and other effects. ----------------------------- FSB impact?
Next on front side bus, the most typical example is the T2050 and T2500, FSB 533 and 667, respectively, that T2050 is the T2500's front side bus is equivalent to shrinking Edition --- For front side bus of the shrinkage, in fact, very little performance impact, but the memory has involved the synchronization problem, nothing to do with the overall use, we do not have much to consider this issue front-side bus. -------------------------- Finally, the problem is the virtualization technology, this is not popular in 2007 Topics of the --- T2300 and T2300E, the two performance parameters are identical, but the latter does not support the VT virtualization technology, this technology is mainly used in professional applications, for our usual everyday applications will not be any impact.
