Intel PentiumD945 is indeed a dual-core processor, but it only solders the two processing cores together, there is no intelligent architecture, the improvement is not large, and the power consumption is extremely difficult to control, so it is called a false dual-core. In contrast, the dual-core processor X2 series of contemporaneous AMD was called true dual-core. But then Intel launched the Core series processor and the subsequent i5 7 intelligent processor, which completely solved this problem, and at the same time greatly improved the cache, front-end system bus frequency, and power consumption control, and the current Core processor series are all true dual-core, so I don't recommend you to buy a Pentiumd processor.

Intel and AMD's CPU dual-core architecture and technical implementation are different, in fact, the performance of the two is about the same, if you have to say who is real and who is fake, then AMD's dual-core is closer to the real dual-core.

D945 is indeed a fake dual-core, and all Pentium D dual-core, Intel divides the CPU core with only one core into two with software, and it becomes two virtual cores, which is the so-called fake dual-core, but this approach can still improve performance to a certain extent for CPUs with only one core. These dual-cores are different from the current mainstream dual-core, whether it is Intel or AMD's mainstream dual-core, it is a real dual-core, it is a real two physical cores, running your software will have two rings, and all Pentium D is only one ring.

Looking at the name, Ben D 945 should be a dual-core processor, you can use CPU-Z to check the number of cores.

As for the truth or falsehood, it is just a play on words, two cores are two cores, and there are many reasons for whether it is done on a chip, including cost, technical characteristics, etc.

Your phenomenon could be the cause of the software or settings.

There is nothing in the CPU and there is a core that has not been turned on, the D945 is dual-core, or you bought a fake at the time?

It's a dual-core, but it's a fake dual-core.

It's just a combination of two cores. Not really dual-core.

I recommend a four-heatpipe Yellow Sea Deluxe Edition, which costs less than 100 yuan.

However, I would recommend that you replace the Pentium D as soon as possible. This thing can't afford to hurt ——— quote an Internet saying.

If you're experiencing Pentium D, I don't have anything to say purely for tossing.

From a practical point of view, it is not as good as selling Ben D directly, on the E2140, the ultra-overclocking performance is good, and the temperature power consumption is much smaller than that of Ben D.

Yes, I was this chip with this U at that time.

Needless to say, absolutely yes

Dual-core. There is actually nothing to compare with each other, AMD's CPU has always been known for its high cost performance (performance to ** ratio), but the disadvantage is that it generates a lot of heat.

Intel's CPUs are expensive but generate little heat.

Generally amd's equivalent of Intel I don't know why, I just see it on computer enthusiasts)

You can right-click on my computer, click on the properties, and there is the relevant information you want!!

AMD Athlon(TM)64X2 Dual Core Processor3600+ is dual-core, and it belongs to the boutique in the low price, with strong overclocking potential, and belongs to the CPU with low supply and consumption, which is generally considered to be better than the Ben D series!!

It's dual-core, and you can see 2CPU running in the task manager.

Without overclocking, the PD820 performs like the 3800+x2.

Recently, AMD has come up with a "true dual-core" concept — a plan that would make potential competitors more uncomfortable than uncomfortable.

To be fair, the "true dual-core" is not rigorous, because whether it is AMD or Intel, its dual-core processor does integrate two processing cores, but the coordination between the two cores and the connection with the surrounding units are different, so that the overall architecture and computing efficiency of their respective processors are different, but this does not exist in the strict sense of the true and false dual-core proposition, it can only be said that there are superior and inferior, if any party accuses the other party of being a "pseudo-dual-core", it will be contrary to the facts, and it seems too domineering, Guilty of unfair competition.

AMD is naturally not so stupid, but he seems to be too happy, proud, and crazy about his high-performance dual-core architecture, if he doesn't say something about it, he really wronged himself, treated himself badly, wasted his "money" in vain, and even had a sense of destroying the heavens, so he launched this "true dual-core" concept while promoting what advantages his architecture has, although it is not very clever, but it is indeed ruthless enough: saying that he is a "true dual-core" does not make people logically deduce" Only oneself is a 'true dual-core'", that is, it is not the same as identifying others as a "pseudo-dual-core", so it avoids the suspicion of exclusive competition; But this is a bit "domineering" after all, but it is a little hidden, because according to the principle of psychological suggestion, people who come into contact with the concept of "true dual-core" are likely to subconsciously and preconceived that only those who have "true dual-core" have "true dual-core", while others are all "pseudo-dual-core" or at least have a great suspicion of "pseudo-dual-core". AMD's "domineering" non-explicit nature may make Intel more bitter and difficult to distinguish, unwilling not to respond, and rushing to respond positively may make people think that there is a lack of self-confidence and no silver here, and it is a feeling that is more uncomfortable than uncomfortable.

In fact, the equally implicit and exclusive "domineering" "Intel Inside" has also overwhelmed AMD for many years (that seems to imply that only computers with this logo are authentic computers), and now AMD is nothing more than a bad breath in the new battlefield with its own way of returning to others. Of course, Intel is also fighting back, and the author noticed that the slogan on Intel's lightbox advertisement is "I'm dual-core", but this seems a bit pale and weak, if it is changed to "Dual-core!" Look at my "isn't it more "anti-domineering"?

Manufacturers have the reason and the right to choose this means of competition, and consumers should always remind themselves that they should neither blindly obey nor deliberately resist psychological cues - compare, analyze, and listen to themselves!

False refers to the support of hyper-threading technology, which can be simulated into a dual-core, and the performance of the computer is not significantly improved. It also occupies resources, resulting in machine jams.

Individually, D945 is more powerful, and it should also be matched with hardware such as motherboards, E2180 doesn't seem to be seen much now, and it was still very mainstream when it first came out of the dual core.

Of course, the E5400 is good, it is not a product of the times. D945 was considered a high-end product at the beginning of the dual-core era,E5400Although it is also counted in the Pentium family,Compared to i3 i5 i7 is definitely inferior,But compared to the previous generation of D945 performance is much stronger,Power consumption is also much better,It seems to be 45nm。。。

D945 has been discontinued in September 2007, E5400 is the most popular CPU around 2010, although E5400 in the main frequency is lower, but E5400 from the architecture and technology, and power consumption are D945 can not be compared.

So the E5400 is certainly much better than the D945.

Don't change itE5400It's better, the performance is also good, it doesn't matter if the main frequency is low, the first-level cache is twice that of 945, and the production process is much better and energy-saving.
