For Intel, the release of the 12th generation Core will be a new milestone, including a new hybrid architecture of large and small cores, 10nm SuperFin process and so on. In addition, the 12th generation Core also supports PCIe 5.0 and DDR5 memory first. Considering that there are currently no graphics cards or SSDs that support PCIe 5.0, its attention is naturally not as good as DDR5 memory.
Although DDR5 memory is listed with the 12th generation Core and Z690 motherboards, its market can only be described as "tepid", because of the high price of DDR5 memory and frequent out-of-stock. Even some DDR5 4800 16G*2 memory hangs out of the price of more than 10,000 yuan, which is enough to "match" the graphics card. The "culprit" that keeps the price of DDR5 memory high is not the memory chip, but the power management chip PMIC, which is currently in supply very tight.
Compared with the mainstream DDR4 memory at this stage, the chip used in DDR5 memory is about 10 times higher in price, coupled with the long 35-week procurement cycle, so that many merchants and process chains are beginning to raise prices, and the price of DDR5 will naturally rise.
The power management chip PMIC is a new component added to the DDR5 standard. From rainbow's tomahawk DDR5 4800 memory, which has been listed, it can be seen that the power management IC is located in the middle of the memory PCB, allowing the memory to manage the operating voltage autonomously. The DDR4 era was designed on the motherboard, and the PCB of the DDR4 memory only had particles or lamp beads. DDR5 moved the chip from the motherboard to the memory, which the JEDEC association called to "reduce the management delay", in fact, it did work, and the conventional operating voltage of the DDR5 memory was reduced from 1.2V in the DDR4 era to 1.1V in the DDR5.
In addition to voltage, the frequency of DDR5 has also increased dramatically. Taking the Battleaxe BattleAX DDR5 4800 mentioned above as an example, the reference frequency of the DDR5 has doubled to 4800MHz, which is more than double the frequency of DDR4 starting at 2133. At the same time, the original 64Bits single-channel data transmission of DDR5 is split into two 32Bits, and the effect of single memory dual channels is split. Although it is different from the traditional dual channel, the theoretical transmission speed is also improved. What is more exciting is that DDR5 also adds the On-die Ecc error correction function, which can improve the stability of memory and reduce the probability of blue screen.
Overall, the performance improvement of DDR5 is still very good. However, in the face of various force majeure factors, it is now in a more embarrassing situation. At the current price, the DDR5 series products are difficult to associate with "incense". Whether it is high, or gradually stable, I believe that you who have experienced the magical DIY market in the past two years have long been strange ~ ~
