The first to step in AMD, Intel introduced a new processor, support LPDDR5!
HTTP: // www.eetop.cn/cpu_soc/6946240.html 2019.10 latest technological developments in the intel.
As we all know, now available in light of the standard memory to run for the LPDDR3, standard memory with this game as DDR4, and LPDDR4 and LPDDR4X used in mobile phones, notebook and does not carry. Because DDR 4 memory has the advantage of high-frequency, low-frequency performance even better than DDR3, it does not make sense with LPDDR 4 on the notebook. Pursuit of performance of the notebook directly on DDR 4 memory normal voltage, for example, Macbook Pro 15 inches, and the pursuit of thin and light notebook still use LPDDR 3, for example, MacBook Air.
So the question is, what LPDDR5 that? It LPDDR3 What is the difference?
LPDDR5 a gimmick?
Previously, JEDEC Solid State Technology Association released LPDDR5 running out of memory standard.
LPDDR5 bus rate of 6400 MT / s, the first edition is twice the LPDDR4, LPDDR4 frequency version than 4266MT / s 50% faster. To achieve this performance, LPDDR5 architecture has been redesigned, up to 16 Banks architecture and multi-clock architecture.
If a match is high-end smartphones common 64bit BUS, data can be transferred 51.2GB per second; replaced 128bit BUS PC, then, breaking 100GB per second should not be a problem.
LPDDR5 for smartphones, mobile tablets a variety of categories, such as ultra-extreme computing needs, even it provides for the automotive critical applications and design features.
LPDDR5 to reduce the overall system power consumption based on an operation by introducing two Data-Copy command and Write-X, reduce data transmission. To meet the automotive and related market demand for data reliability, LPDDR5 on the interface between the SoC and DRAM introduces support link error correction code (ECC) of.
LPDDR5 voltage and LPDDR4X are as 1.1V, a signal voltage is 250mV. Idle state, the current will be reduced by 40%, it can significantly reduce power consumption.
According to the IC manufacturers revealed Synopsys, LPDDR5 introducing differential clock WCK, GDDR5 like, so as to enhance the frequency without increasing the pin.
LPDDR5 VS LPDDR3
LPDDR3 application memory and LPDDR5 are standard on notebook computers. As already we talked about what is LPDDR5, now let us first understand what is LPDDR3, and then compare both come under in the end what is the difference now.
LPDDR3 memory is one of the existing standards, which is the third generation LPDDR RAM technology. Its data rate 1600Mbps, 50% faster than LPDDR2.
LPDDR3 difference LPDDR5 and is divided into the following points:
Bandwidth and minimum bandwidth LPDDR5 6400 MBit per second, and the bandwidth of the LPDDR3 3200 Mbit per second, the former is twice the latter. WCK clock, LPDDR5 joined the WCK clock function to enhance performance. WCK clock operating frequency is the clock frequency of twice or four times. ECC function, ECC error correction may be performed during read and write operations. DSM mode, a DSM mode, the IDD current LPDDR5 may be reduced by more than 40%. The modes are activated in the self-refresh state or an idle state. Under ideal conditions, DSM mode disables all input and output buffers and all internal circuits of the power supply . Channel, LPDDR5 each channel has 16 memory bank, and each channel is only 8 LPDDR3 Bank. LPDDR5 a single 32-bit channel, LPDDR3 the use of 16-bit two-channel. Voltage, LPDDR5 voltage of 1.1V, and the voltage is 1.2V LPDDR3
On the whole, LPDDR5 significantly enhance performance, lower power consumption than the previous generation a lot. In addition, it also added some new technology. Next-generation storage technology is the key to promote high quality images and video as well as ultra-high-definition gaming and machine learning.
Intel is not just to follow up on technology
LPDDR5 now represents the next generation of storage technology, presumably there will be many manufacturers to follow up on this technology, Intel is no exception. Why do you say?
Memory corresponding to the relay station, during use of the computer program is run in the computer memory, the memory effect is used to temporarily store data exchange apparatus cpu computed data, and a hard disk.
LPDDR5 bandwidth is increased, which helps improve the operating speed of the computer, to reduce the CPU write hard time to improve overall efficiency. For example: When you want to play a masterpiece 3A, LPDDR3 memory to load the game with 54 seconds, LPDDR5 may be as long as 10 seconds.
It would appear, LPDDR5 helps enhance computer performance. Intel introduced support LPDDR5 the processor is not just to follow up on technology, but also to seize the market, the introduction of new technology, attract more PC vendors to increase revenue.
AMD as Intel bigger competitors, and not to launch support LPDDR5 processor messages. This means that Intel can be the first step, to occupy more CPU market, ahead of a blow to the opponent.
Intel Tiger Lake equivalent skipped LPDDR4, adding support for direct LPDRR5 of. Another highlight is its 10nm process technology, not just squeezing toothpaste directly to AMD . The AMD Dacentrurus processors currently supported memory specifications are DDR4, launch next year, Renoir APU (7nm) supports LPDDR4X. Both of them in the end who is stronger, now still in doubt.
For PC makers, in marketing, LPDDR5 used to support the Intel processor , you can add a new selling point for the product, in order to attract more users to buy.
For the user, it can be used for better performance of the computer, thanks to Intel 's processors introduced support for LPDDR5 of. Users will trust the Intel of the CPU , the brand also increases the viscosity.
