The first step is to explain the terms as a prerequisite for discussing with you:
"PGA": Generally refers to the situation where the original cpu has its own pins. The u pins are made from the original factory, and the quality and workmanship are guaranteed by testing, which is relatively stable and reliable;
"BGA": It means that the cpu does not have pins when it leaves the factory, and the pins are welded through secondary processing in the later stage. Due to the uneven quality of the post-adding process, the quality of the cpu of the bga is unpredictable. Some will be close to the original quality, but some will appear. Poor contact, resulting in unstable operation of u.
"Official version cpu": It is a symbol of quality, stability and security, but it is generally more expensive.
"Es version of cpu": that is, engineering sample goods, which are usually sent by U factory to major customer manufacturers for testing and R&D. The es version is divided into a display version and a non-display version. The display version is also the "positive display" version or "qs" version mentioned on Taobao. This version of u can see the full model of u in the computer properties. , Same as the official version display, except that there will be an (es) mark. It can be said that the qs version of the cpu is infinitely close to the official version of u, and the quality is generally better and more stable. The undisplayed version of u, that is, the ordinary es version of u, is of mixed quality, some are more stable, and some are more problematic.
"Step": It is the revised version of the cpu, because the pre-factory cpu cannot be perfect, it is inevitable that there will be some bugs, such as some functions are not supported, or the heat is relatively large, or even the operation is unstable. This needs to be corrected The cpu process has been improved to a certain extent, just like the sp patch released by the windows system. It can be seen from this that the performance and quality of the u released in the later period is better, and of course it is updated. For example, the e8435 is a profound example. The 8435 stepped in the early release is c0, the rated power is 55w, and the heat is huge; but after the later revision The rated power of the e0 version 8435 becomes 44w, and the heat is significantly reduced. It is also for this reason that the price of CPUs with lower stepping steps is more expensive than the earlier ones, but generally speaking, there are reasons to be expensive.
"TDP": Rated power. This data directly affects the heat generation of the cpu and the standby time of the notebook. In theory, the lower the tdp, the better, but a too low tdp will affect the performance of u, so to find a balance between heat and performance, it is to choose A homework to do when u.
"U's process process": The unit is nanometers, generally 45nm, 32nm. The lower the process technology, the higher the integration and the lower the calorific value, which is easily overlooked as one of the parameters for selecting u.
Other data, such as front-side bus, L2** cache, FSB, multiplier, etc., are more common, so I won’t go into details here. . .
-There is one point that needs special explanation. It does not mean that the official version of u is all pga, and the pin and the version of u have nothing to do.
Finally, summarize the quality ranking of u in various situations (for reference only):
The latest step of the official version of pga (the final home of Miren)》
qs version of pga latest step (strongly recommend cost performance)》
The official version of pga old stepping (recommended) "
The latest step of the official version of bga (recommended)"
es version of pga latest step (recommended) "
The official version of bag old stepping, qs version pga old stepping, qs version bga new stepping (if you need to buy, you must carefully test in depth)"
es version of pga old stepping, es version of bag new stepping (not recommended to buy)"
qs version of bga old stepping, es version of bga old stepping (the worst and most prone to problems, the cheapest u, strongly not recommended, self-masochistic and scientific madman ignore)
Okay, let’s get to the point, and talk about the difference between the three u:
1. First of all, performance, x9100, t9900 and e8435 are exactly the same, all 3.06, 1066, 6m, there is nothing to entangle with, the same is the same, I have used 9100 and 8435.
2. Then talk about positioning and difference.
The x9100 is the supreme version of u. The common feature of the supreme version is that it does not lock the frequency multiplier. If your machine can super double the frequency, this u is god. His price is more expensive because of this. But as far as I know, there are very few notebooks that support overclocking.
The t9900 is the pinnacle of the t series. The biggest difference from the x9100 is the frequency multiplication lock. Of course, the difference between power consumption and heat will be discussed below. The current price is also very expensive, and most of them are post-stitched bga, which makes people worry about stability, and I have not tried it.
e8435 is more complicated. It was originally used on Apple's all-in-one machine macmini, but it can also be used on notebooks. The price is very affordable, mostly the official version of pga.
In fact, from the perspective of frequency multiplication, the 9900 and 8435 are exactly the same, and both are the 9100 with the multiplier version.
3. Talk about power consumption and heat generation.
9100tdp is 45w, 9900 is 35w, e0 version 8435 is 44w, c0 version 8435 is 55w, so the calorific value is 9900 "8435 (e0) "9100 (e0) "9100 (c0) "8435 (c0 ).
According to my usage, the temperature of the everest grilled chicken on my m50 is 75 degrees for the 9100 of the e0 version and the 8435 of the e0 version, and it is about 55 degrees for daily use. The 9100 and 8435 of the c0 version have not been tried, and the 9900 has not been tried.
But one thing is very clear, the c0 version of 8435 is very hot, and many brothers say 90 degrees +, and some even 100 degrees. Seriously, it is not recommended to buy this u at a cheap price.
Because I have used t9800e0, the fever of t9800 is indeed a lot lower, with an average of 5-8 degrees, so it is inferred that the fever of t9900 may be about 5 degrees lower than the 8435 and 9100 of e0
ConclusionThis is the end of the related introduction about q9000 and qx9300. Please correct me if there are any deficiencies.
