Random memory is one of
the most important components of your computer, and in fact, this component is
found in most smart devices in general, that is, your smartphone also includes
random memory, as well as your home gaming device, and perhaps some other accessories
and devices starting from the watch Smart TV and Smart TV! These memories are
used to store files that the device needs to download very quickly, as we know,
but today we will talk about a more specialized topic, which is the difference
between modern technologies for DDR4 and DDR5 RAM.
In this article, we will
tell you all the information you need to decide whether to use these new RAM,
or stick to DDR4 memories, so this article is of interest to you if you intend
to assemble a new device of course, especially since DDR5 RAM will not support
previous generations Backward Compatibility.
Differences between DDR4 and DDR5 RAM: Speed
The first difference
between these two types of random memory is the bandwidth, or let's say
"speed", this term is the literal translation of the term Bandwidth,
which you have certainly come across before as long as you are interested in
the fields of computers and hardware, and the memory bandwidth is measured
based on the speed of data transmission between The processor, the storage disk
of any type and between the same memory in sequential operations of course, and
as you can guess, the more bandwidth in the RAM, the faster and more efficient
it will work.
Currently deployed DDR4
memory provides bandwidth of up to 3.2 Gbps for each of its pins, while DDR5
will come with almost double this number, i.e. 6.4 Gbps.
In addition to the
above, the new DDR5 RAM technology will provide double frequency as well, as we
all know, the DDR4 memories in our devices offer a primary frequency in the
range of 1600 to 3200 MHz, and some of the leading RAMs offer between 4000 and
5000 MHz, while DDR5 memories will provide numbers up to 8400 Megahertz! These
will range from 3200 to 6400 MHz as initial frequencies, but will reach the
huge number of 8400 MHz in the most expensive and powerful models.
DDR5 power consumption compared to DDR4
The second difference
between these two types of RAM is power consumption, and here we note that the
evolution between DDR5 and DDR4 is really big and noticeable. In DDR4 RAM, the
power management process was done by the motherboard itself, but in DDR5
memory, the process would be done through a separate chip called PMIC (Power
Management Integrated Circuit).
This means that the
random memory will be smarter and will receive only the power it needs, no more
and no less, and this will eventually lead to an adaptive power consumption
with the quality of your use and not a constant power consumption, and in
general, DDR5 memory will be more professional in terms of managing and saving
energy and electricity.
Channel architecture in DDR5 RAM
Here we encounter
another big difference between the two generations, and you may have heard of
the term Dual Channel or even Quad Channel or Quad Channel, which is done by
placing your random memories in the motherboard in a binary or quadrilateral
and in a specific order, and this technology contributes greatly performance
boost, especially with Ryzen chips. The technical basis for this process is
that the memories in Dual Channel mode are distinctly interconnected with the
central processor, and it is then able to access different sectors of data
inside the random memories.
The revolutionary and at
the same time strange change in DDR5 memory is that each chip will be dual
channel in nature! That is, placing only one chip in your motherboard will mean
that you are using the Dual Channel feature without a problem, and the more chips,
the greater the number of channels accordingly, and the memories will often
differ in terms of dealing with this feature from each of the companies
producing within the technical field.
The difference between the RAM capacity in DDR4 and DDR5
This is the last big
difference between the two types of RAM we are talking about, which is the
total space - or capacity - for each chip separately, and here we note that the
current DDR4 chips have a maximum capacity, as they accept up to 16 * 16 GB,
i.e. a total 265 GB, which equals 32 GB, but the situation for DDR5 will be
different, as each chip will support up to 1024 GB, which is a total of 128 GB.
This
means that the DDR5 memory will have a capacity of 128 GB for one piece of RAM!
It is a very huge number, and taking the feature of its support for
Dual-Channel in the form of a single memory, it means that in the future we may
be able to buy a single 128GB RAM chip that supports Dual Channel!
The
aforementioned are the main differences between the two types of memories, and
perhaps now you want to know what you should do!
Here, the mind is more likely to stay with the current DDR4 memory, especially since it still works excellently. On the other hand, the aforementioned differences may be more important for a person with a very professional use and not an ordinary user or player.
