Among the many hardware of DIY, the model of the CPU can be said to be the most friendly, after all, AMD and Intel can easily judge its positioning, even Meng Xin can see at a glance that the positioning of i9 is the highest, followed by i7, i5 and i3, even AMD here is the same, so there are many players aiming at i7/R7 and i9/R9.
But don't be happy, although it seems simple, but due to the difference in algebra, resulting in the actual i7 is not necessarily stronger than the i5, for example, the entry product i3-12100F in the 12th generation Core has a better overall performance than the i7-5960X, so simply looking at the i7 may not help you choose the right CPU for you.
In addition, the merchants have long looked at the new psychology, after all, want to use low prices in exchange for high performance is the mentality of everyone, so the i9 level CPU, i9 level game console is also born.
For Mengxin, who does not understand, seeing i9 is naturally a very high-end positioning, and the performance of i9 level will not be bad. But in fact, the merchant describes it this way just to clean up the inventory, and actually sells you just an old Xeon.
Taking a treasure and a certain Duoduo as an example, the CPU of the "i9-level host" configuration with a price of 3,000 yuan is E5-2673, and it is 12 cores and 24 threads in the core, which looks like the momentum of the i9, right? But what the merchant didn't tell you is that this CPU uses a 22nm process, and the main frequency is only 2.4GHz, so you can roughly know how its performance is.
If there is still hope for the performance of this CPU, in the DIM at a price and a penny, the retail price of the E5-2673 is currently around 250 yuan, do you still think it has i9-level performance?
Are all 99 frames you dare to believe?
For gamers, especially pay attention to the CPU frequency rather than the number of cores and threads, because most of the current games need high frequency to provide a better experience, and for multi-core optimization version is also 4 cores and 8 threads, that is, if the CPU main frequency is low, even if there are more cores and threads, it can not play a strength, your CPU is really not as good as i3.
In fact, in order to bring goods, play word games is not in the minority, for Meng Xin naturally can not let down their vigilance, if you want to buy a cheap assembly machine, or first learn about the relevant knowledge, have more understanding of the hardware and then buy will be more reasonable, to avoid greed and cheap to eat big losses.
