Why are assembled computers so cheap on Taobao? What’s the trick?

Faced with the dazzling array of assembled computers on Taobao, many people wonder why their prices are so low. PHP editor Xiaoxin launched an investigation into this and revealed the tricks behind Taobao’s low prices for assembled computers. Interested friends may wish to continue reading to find out.

Why are computers on Taobao so cheap? Because there is a lot of foreign garbage, second-hand refurbished, washed motherboards, and mining cards in it. Let me analyze for you why it is so cheap.

Foreign garbage configuration

Speaking of foreign garbage, in fact, when it comes to computer installation, it mainly refers to Xeon series CPUs and South China’s X series motherboards. These CPUs are basically server CPUs, except for the first generation Apart from the classic E3, there are basically not many advantages at E5, especially with the recent emergence of the third generation Ryzen, the number of cores and threads has become the same as that of the server level. Nowadays, many Taobao hosts are advertised as I7 level hosts, with performance comparable to I7. In fact, it is completely a gimmick, because if you look at their accessories in detail, they are basically all kinds of Zhiqiang E5 garbage series. Although you see other There are a lot of cores and threads, but if you look at its main frequency, we know that the basic main frequency hovers around 2.5GHZ. You must know that this main frequency is basically higher than that of the Core generation.

So a friend wants to ask, wouldn’t it be more powerful if there are more cores? They have 8 cores and 16 threads. If you open the hardware manager and look at the row of cores, you will be scared to death. But what I want to say is that except for those of us who generally work in post-production and need multi-core multi-tasking, in fact, our general applications are still It can only work on one core, and most applications are not ideally optimized for multiple cores, unless your computer is often in multi-tasking mode. Let’s talk about the games we like, especially large-scale 3A-level games. These large-scale stand-alone games are very sensitive to the main frequency of the CPU. For the sake of stability, server CPUs generally do not have very high clock speeds. Except for the E3 series, which is an exception, you cannot compare other server CPUs with consumer-level CPUs. There are also high-frequency Zhiqiang series CPUs, but they are really expensive.

The price of these server CPUs is generally not high. Coupled with the ECC series DDR3 memory sticks, a 32 GB memory stick only costs 1,780 yuan, plus South China's 300 to 400 yuan fast ones. The motherboard is paired with some flagship graphics cards from two or three generations ago. Although it is a flagship graphics card, after all, it has been a long time and its price is basically not very expensive.

Renovation, mining card hardware

Another reason is that various Internet cafes have eliminated machines or mining cards, which have been refurbished after secondary recycling. On the surface, they are basically indistinguishable from newly purchased ones. Second, they are second-hand after all, and the applicable environment of these things at that time was basically not very good. The general price of these things is much lower than the normal price.

Finally, OEM manufacturers have flowed computer raw parts into the market for various reasons. These items are basically sold at second-hand prices, so these accessories are also quite cheap.
