Intel 12th generation Core is really powerful in terms of performance and power consumption, which has begun to make AMD really feel the pressure, and also let more players and users look forward to the upcoming release of more non-K series models.
However, compared with the popularity of the processor, the DDR5 memory brought by the first launch is tepid, mainly because the current price of DDR5 is too high, and there are often out-of-stock situations.
On the e-commerce platform, the price of two DDR5-4800 16GB requires two or three thousand yuan, at least four or five thousand at high frequencies, and even some exceed 10,000 yuan, which is more magical than the graphics card.
The reason for the high price of DDR5 memory, in addition to the management of the new generation of the first market, the power management chip PMIC is the "culprit", its price is 10 times more expensive than the DDR4 used, and the supply is very tight, the long 35-week procurement cycle, so that the industrial chain and shelves are constantly raising prices, the price of DDR5 memory is naturally rising.
Speaking of power management chip PMIC, this is a very critical change for DDR5.
As shown in the figure, the new product surrounded by multiple capacitors in the middle of the DDR5 PCB is a power management chip, which allows DDR5 memory to manage the operating voltage independently.
In the DDR4 era, it was still on the motherboard, and in the DDR5 era, it was moved to memory, which the JEDEC association, which is responsible for setting the standard, said that this was to "reduce the management delay" and also to further reduce the voltage from 1.2V to 1.1V.

In addition to the voltage reduction, DDR5 is still continuing the frequency, starting at 4800MHz, more than doubling compared to DDR4-2133, of course, the delay has also gone up, the current frequency is not enough to play the advantages of DDR5, need to wait until 6400MHz is popular.
In addition, DDR5 also splits the original 64-bits single-channel data transmission into two 32-bits, realizing the effect of a single memory dual channel. Although the performance is different from the traditional dual channel, the performance is not the same, but the transmission speed has still been improved.
Another exciting point is that DDR5 adds the On-die Ecc error correction function, which can further improve the stability of memory and reduce the probability of system crash and blue screen.

Overall, the improvement of DDR5 in all aspects is remarkable, but in the face of some force majeure, it is still in a more embarrassing situation, especially the price, it is difficult to connect with "incense".
Of course, I believe that those of you who have experienced the magical DIY market in the past two years have long been strange.
